Defendant was indicted for the murder of Mrs. Doris Gillie and was tried capitally at the 8 August 1988 Criminal Session of Superior Court, Durham County. The jury found defendant guilty of first-degree murder on the theories of premeditation and deliberation and of felony murder, guilty of discharging a firearm into occupied property, and guilty of attempted robbery with a dangerous weapon. Following a sentencing proceeding pursuant to N.C.G.S. § 15A-2000, the jury recommended a sentence of death for the murder conviction. On 25 August 1988, the trial court sentenced defendant to death in accordance with the jury’s recommendation for the murder. Defendant was also sentenced to consecutive terms of ten years for discharging a firearm into occupied property and forty years for attempted robbery with a dangerous weapon.
Defendant brings forward numerous assignments of error relating to both phases of his trial. After a careful consideration of these assignments, as well as the transcript, record, briefs, and oral argument, we find no error in the guilt determination phase of defendant’s capital trial; however, we find that the trial court erred in denying defendant’s motion to. dismiss the charge of attempted robbery with a dangerous weapon, and we therefore vacate the judgment as to this conviction. As this is the basis for the only aggravating circumstance found by the jury in the capital sentencing phase, we must also vacate the sentence of death and impose a life sentence.
The evidence presented by the State tended to show that in the late afternoon of Wednesday, 19 August 1987, two teenagers, Eric Jeffrey and Lee Percell, met with defendant, who had just moved into the neighborhood with his pregnant girlfriend, Karen Curtis. Percell, Jeffrey, and defendant talked for a while and then decided to go to the store to buy some beer or wine. Defendant first went to his house to get some change, and then the men started to walk to the store. After making their purchases, the three men stopped at several houses on the way back, including the Parker residence. There, Jeffrey testified, two people were fighting with each other on the porch. Defendant went onto the porch to see what was going on and recognized one of the occupants, Patricia Parker, from school. He started “coming on strong” to her. Defendant then showed her and her brother a large pistol *369which he was carrying in a gym bag. He put the gun away and left with Percell and Jeffrey.
The men then continued on to the “Greenhouse,” a group home, to talk to some of the residents. Defendant pulled up his shirt and revealed a pistol in his waistband. After questioning, defendant told one of the residents, Erica Joyner, that the gun was real. Ms. Joyner took the gun and handed it to Percell. Ms. Joyner testified that Percell said the pistol was his and that Percell put the pistol in his pants before they left. After the weapon had been shown to the young women, they went back inside the house. Jeffrey and Percell walked off, and defendant caught up with them. While walking, according to Jeffrey, defendant asked Jeffrey and Percell if they were “down to make money.”1 When Jeffrey replied no, defendant called him a “pussy” and a “chicken.” Jeffrey said he could be that. Percell started laughing; as defendant waved the pistol in Jeffrey’s face, defendant demanded to know why Percell was laughing. Defendant then left the two and walked toward the Durham Gospel Center. Jeffrey testified that, about five minutes after defendant left them, they heard the sound of shots.
After the Wednesday night prayer service at the Gospel Center, Mrs. Doris Gillie had sent her two children home with some friends. Mrs. Gillie stayed later to talk to some friends and went to the parking lot at about 8:45 p.m. on 19 August 1987. Another attendee, Eddie Sarvis, went to the parking lot at the same time. As he left the parking lot, Mr. Sarvis saw Mrs. Gillie’s headlights behind him. He heard a shot just as he pulled out of the lot. He thought Mrs. Gillie’s car had misfired and continued to leave. As he turned the corner, he heard three more quick shots, and then he backed up. He saw two persons running down the street. Mr. Sarvis went back toward the church and saw Mrs. Gillie’s car still in the lot. He drove into the lot and then saw that Mrs. Gillie’s window was shattered. He sent his sister, who was with him, for help.
Mr. Sarvis attempted to assist Mrs. Gillie, who was wounded but still in the car with her seat belt on. The car was in park with the doors locked. Mr. Sarvis reached through the shattered window, opened the door, and "attempted to remove Mrs. Gillie, *370who was trying to talk, from the vehicle. Before being removed from the vehicle, Mrs. Gillie lapsed into unconsciousness. Mr. Sarvis attempted CPR until the ambulance arrived. Without regaining consciousness, Mrs. Gillie died shortly after arriving at the hospital as the result of two gunshot wounds. The forensic pathologist recovered a .38-caliber slug from her body during the autopsy. He noticed no powder burns on her clothes.
Meanwhile, Jeffrey and Percell had gone back to Percell’s home and were sitting on the front porch when defendant came up. Defendant told them he had shot someone and “had to kill them.” Later that evening, defendant ran into them again and told them not to tell anyone what he had done.
Crime scene investigators found several bullet holes in the interior of the vehicle consistent with the shots being fired into the vehicle through the driver’s window and in a downward angle. Skid marks and broken glass suggested that Mrs. Gillie had moved the vehicle in an attempt to escape. Her pocketbook was found unopened on the front passenger seat. Her body was between the purse and the shattered driver’s window.
Later, the police, with the consent of Karen Curtis, searched the home she shared with defendant. The police found a shell casing in a closet. Additionally, the police obtained a .38-caliber pistol in a “mock takedown.”2 The ballistics expert opined that the slug recovered from Mrs. Gillie’s body, as well as the shell casing, had been shot from the recovered .38-caliber pistol. However, the expert could not say the cartridge casing was from the Gillie murder.
On 20 August 1987, defendant was arrested and gave a statement denying involvement in the killing. After learning from the police that Erica Joyner had told them about his waving the pistol around, he admitted that he had shot the gun at the urging of Percell and Jeffrey but claimed that he did not mean to shoot Mrs. Gillie. The State was allowed to offer, over objection, a statement that defendant made thereafter: “You see, I’m going to get a psychiatrist. I’m going to beat you. You see, I’ve told you what *371you want to hear but with a psychiatrist, I’ll beat you. Now, take me to jail.”
While incarcerated in Durham County jail, a fellow detainee, Richard Bradshaw, overheard defendant and another inmate talking. The inmate asked defendant if he had shot the woman he was charged with killing. Defendant replied that “he had burned her and that ... if it hadn’t been for some bitch seeing him earlier that day, he wouldn’t be in jail, seen him with the gun.” Defendant also stated that the police would not be able to locate the gun.
Defendant presented evidence through Lee Percell and his attorney to show that while defendant, in fact, announced his intent to “burn” someone, he did not mention robbery. Percell’s attorney testified that Percell had consistently said that defendant had stated that he was going to “burn somebody” but that defendant had said nothing about robbery. No psychological or psychiatric evidence was presented at the guilt phase of the trial.
At the sentencing phase, the State relied on its guilt phase evidence to prove the aggravating factor of attempted robbery with a dangerous weapon. Defendant’s evidence focused on his mental condition. Defendant presented mitigating evidence through his father; Brad Fisher, a clinical psychologist; and William Hussey, a former counselor at a rehabilitation program that defendant had attended.
Pretrial Issues
I.
[1] Defendant contends that the trial court erred in allowing the capital case against him to proceed without the appointment of additional counsel to assist him and that this violated the mandate of N.C.G.S. § 7A-450(bl). We disagree. On 21 August 1987, defendant appeared in District Court, Durham County, where the court found that defendant was indigent and “not financially able to provide the necessary expenses of legal representation.” The court appointed one attorney, E.C. Harris, to represent defendant. Later, attorney Harris moved to withdraw as counsel for defendant on the grounds that attorney Tim Oates had been retained by defendant’s family to represent defendant. On 5 October 1987, the court allowed Harris’ motion to withdraw. From that time forward, attorney Oates alone represented defendant.
*372On 22 March 1988, defendant appeared in court, represented by Mr. Oates, as the case was calendared for trial in Superior Court, Durham County. During this proceeding, the district attorney raised the issue of defendant’s representation, and the following exchange occurred:
[STATE]: I want to address one other situation. Mr. Oates has made an appearance as counsel of record and during the course of the preliminary proceedings in this matter there was a questions [sic] as to who would be representing Mr. McDowell. He, my impressions is [sic], has been retained by Mr. McDowell’s family to represent Mr. McDowell.
Mr. OATES: That’s correct.
[STATE]: Since this is a capital case, quite honestly, I want the record to reflect that ... he is Mr. McDowell’s choice and because [General Statutes chapter] 7A, as the Court knows, allows proceedings for indigents in which there is also additional counsel situation available, I would like for the record to reflect before we get too far along what the status is and where we are.
COURT: Let me ask the defendant, Mr. McDowell. Mr. McDowell, is Mr. Oates seated with you at the table your attorney in the trial of this easel
Mr. McDowell: Yes, sir.
COURT: Are you satisfied with him? The State’s attorney indicated that your family retained Mr. Oates and you consider him retained for you and you accept him as your lawyerl
MCDOWELL: Yes, I do.
COURT: Thank you.
[STATE]: Your Honor, I think he probably is otherwise indigent because of his situation and I take it by this that he is waiving any additional counsel because of his indigent status and Mr. Oates is his counsel of record.
[COURT]: Do you understand, Mr. McDowell, and I will ask you the same question. You may be indigent and cannot afford a lawyer yourself. Mr. Oates is your attorney and he is retained by your family to represent you[J that you waive any other rights that you may have to an additional court *373 appointed lawyer and you accept Mr. Oates as your attorney, is. that corrects
Mr. McDOWELL: Yes, sir.
(Emphasis added.)
On appeal, defendant assigns as error the failure to appoint additional counsel on his behalf in a timely manner. N.C.G.S. § 7A-450(bl) specifically provides that “[a]n indigent person indicted for murder may not be tried where the State is seeking the death penalty without an assistant counsel being appointed in a timely manner.” (Emphasis added.) This Court has noted that this section was passed due to a “special concern for the adequacy of legal services received by indicted indigents.” State v. Hucks, 323 N.C. 574, 577, 374 S.E.2d 240, 242 (1988). The right to the appointment of additional counsel for indigent defendants in- capital cases is statutory, not constitutional. State v. Locklear, 322 N.C. 349, 368 S.E.2d 377 (1988). An indigent person for whom the State must provide counsel is defined as one “who is financially unable to secure legal representation and to provide all other necessary expenses of representation.” N.C.G.S. § 7A-450(a) (1989) (emphasis added). The trial court makes the final determination of indigency, and this may be determined or redetermined by the court at any stage of the proceeding at which an indigent is entitled to representation. N.C.G.S. § 7A-450(c) (1989).
Here, defendant was found indigent by the trial court on 21 August 1987 and was subsequently represented by court-appointed counsel E.C. Harris. However, by the 22 March 1988 proceeding, defendant had obtained private counsel, attorney Oates, retained by members of his family, and E.C. Harris had been allowed to withdraw as court-appointed counsel. During the pretrial proceeding, defendant explicitly accepted attorney Oates as his counsel of his own choosing. We hold that from this point on in the pretrial proceeding, defendant was not an indigent within the meaning of N.C.G.S. § 7A-450(a), as he had, through his family, secured private representation and therefore was not entitled to the appointment of assistant counsel.
II.
[2] Defendant contends that the trial court erred in not conducting an inquiry to determine whether defendant had voluntarily and intelligently withdrawn his notice of intent to present an insanity *374defense. We disagree. .On the first day of trial, defense counsel, pursuant to N.C.G.S. § 15A-959, filed a notice of intention to present an insanity defense. Shortly before jury selection, defense counsel informed the court that he had decided not to rely- on the insanity defense, and the following discussion took place:
[COURT:] ... I need to tell the jury if [insanity] is to be presented as an affirmative defense, and I wanted to talk to your client about it up one side and down the other.
[Defense Counsel]: We have. We have, Judge.
COURT: The defendant is nodding his head, yes.
[DEFENSE Counsel]: Judge, I have talked to his parents. I have talked with his psychiatrist in the past, psychologists. I have talked with experts in the Willie M field, and at this time I am informing [the district attorney], Judge, that we are not at this stage of the proceedings, the trial itself, [going to] put in an insanity defense.
COURT: If not now, when?
[DEFENSE Counsel]: Well, your Honor, if he’s convicted not as an insanity defense, but obviously it is a mitigating factor, but there are a lot of things that will show up at that time if it comes to that stage, Judge.
COURT: Okay.
[District Attorney]: It is my impression that he is withdrawing the notice that was filed.
COURT: Insanity, of course, is an absolute defense. If the jury finds insanity, they find the person not guilty by reason of insanity.
[DEFENSE Counsel]: But Mr. McDowell, his parents, like I said, and the people that I have talked with, I do not feel that we could convince the jury of that, Judge.
COURT: And, of course, the burden of proof is on the defendant, not beyond a reasonable doubt, but simply to the satisfaction of the jury, but, nevertheless, it is a major strategic decision.
[DEFENSE Counsel]: And a very difficult decision in this case, Judge.
*375COURT: I know, but you have talked it over with your client in detail and with his family?
[Defense Counsel]: Yes, sir.
COURT: And he has made the decision. He does not want to present that affirmative defense.
[Defense Counsel]: Is that correct? (Asks [defendant])
[Defendant]: Yes, sir.
[Defense Counsel]: He says, yes, your Honor.
(Emphasis added.) Additionally, after the presentation of all evidence, but before the defense rested, the court, out of the presence of the jury, again made inquiry of defendant to make certain that defendant continued to agree to his pretrial decision not to present further evidence of various psychiatric witnesses, and he said he did.
A claim of insanity is an affirmative defense to a crime and does not require a formal inquiry as set forth in N.C.G.S. § 15A-1022, even when a defendant decides to waive his right to plead not guilty. State v. Avery, 315 N.C. 1, 337 S.E.2d 786 (1985). We find that the record reflects sufficient inquiry by the trial court, both prior to jury selection and after the close of defendant’s evidence, of both defendant and his lawyer, to determine that the decision to withdraw the notice of his intention to present an insanity defense was knowingly concurred in by defendant.
III.
[3] Defendant further contends that the trial court erred in denying defendant’s motion to suppress the search of his apartment and improperly admitted into evidence the shell casing seized from the apartment which he shared with Karen Curtis. We disagree.
N.C.G.S. § 15A-222(3) provides that the consent needed to justify a search and seizure may be given “[b]y a person who by ownership or otherwise is reasonably apparently entitled to give or withhold consent to a search of [the] premises.” State v. Moore, 316 N.C. 328, 333-34, 341 S.E.2d 733, 737 (1986). The record reflects that the apartment was listed in Karen Curtis’ name. She lived there and paid the rent and utilities from her welfare check. Defendant was listed on the utilities form as her roommate. There was only one bedroom, which she shared with defendant, and only one closet, in which their clothes were commingled. Defense counsel conceded *376during voir dire that Curtis “had an equal right in that apartment,” but he asserts that the search was not based upon lawful consent because Curtis did not have sufficient mental ability to voluntarily consent to the search. We find that Curtis possessed common authority with defendant over the searched premises.
When the validity of a consent to search is questioned, the trial court must conduct a voir dire hearing to determine if the consent was voluntarily given. State v. Fincher, 309 N.C. 1, 305 S.E.2d 685 (1983). “Consent” is defined as “a statement to the officer, made voluntarily and in accordance with requirements of G.S. 15A-222, giving the officer permission to make a search.” N.C.G.S. § 15A-221(b) (1988). In determining whether a consent to search is “voluntary” or a product of duress or coercion, express or implied, the trial court looks to the totality of the circumstances. State v. Brown, 306 N.C. 151, 293 S.E.2d 569, cert. denied, 459 U.S. 1080, 74 L. Ed. 2d 642 (1982).
Here, the trial court conducted an extensive voir dire and heard testimony concerning the events surrounding the signing of the consent form. The trial judge found as facts the following: When the police arrived at the apartment with the arrest warrant for defendant, no one was home. When Karen Curtis arrived at the apartment, the officers identified themselves, told her they had a warrant for defendant’s arrest, and requested permission to search the apartment but stated that she had the right to refuse. After Detective Smith read Curtis the form for permission to search without a search warrant, she signed and dated it and said she understood it. Curtis told the officers that defendant had the key but that a window was raised and they could take the screen off the window. After gaining entry into the house, the officers and Curtis went into the bedroom, where the shell casing was found in the closet. Curtis then made a written statement to Detective Smith which included the prior day’s activities and that she fully and freely and with complete understanding consented to the search.
The trial court also found that Curtis, a twenty-two-year-old woman who is mentally retarded, dropped out of high school in the twelfth grade but can write her own name and can read to some extent. The court further found that she continues to have legal custody of her child and has never been declared legally incompetent.
*377Defendant presented testimony during the voir dire hearing from Mary Ann Rowe, Curtis’ social worker, which tended to show that Curtis is mentally retarded. Rowe stated that Curtis may have been able to understand if an officer told her that she had a right to not let him in the apartment, but that she “responds favorably to any authority” and that she does not have the will to disagree with someone in authority. Rowe also stated that Curtis is very “exploitable by others, and needs protection.”
This Court has held that a person’s subnormal mental capacity is but one factor to be considered in determining whether a knowing and intelligent waiver of rights has been made. See State v. Fincher, 309 N.C. 1, 305 S.E.2d 685. Despite the testimony cited by defendant as indicative of Curtis’ limited mental abilities, there is sufficient evidence in the record that she understood the nature and consequences of her action in signing the form and that she voluntarily consented.
The trial court concluded that Karen Curtis freely, knowingly, intelligently, willingly, and voluntarily gave consent to the search of the apartment; that she was not just submitting to authority; and that the officers acted in good faith without any knowledge of any possible mental limitations that Karen Curtis might have. We find that the trial court’s findings of facts are supported by voir dire testimony and that these findings fully support the legal conclusion that Karen Curtis’ consent to the search was voluntarily and intelligently given, free from any duress or coercion. We hold that the trial court correctly ruled that the spent shell casing seized pursuant to the search was admissible.
■Jury Selection Issues
IV.
[4] Defendant next contends that the trial court erred in excusing juror Lennie for cause based on his stated opposition to the death penalty. During the trial court’s initial statements to three jurors during voir dire, juror Lennie interjected the following:
I read something in the newspaper relating to the facts of this case that seemed to indicate . . . that I might not be acceptible [sic]. I don’t believe in either an individual’s or a society’s rights to kill someone in the death penalty.
*378Thereafter, the court specifically directed the following question to the jurors:
Is there anything about capital punishment which is one of the two that the jury is to consider in phase two, the death penalty, that is such that any of you feel that you could perhaps not give both sides the same fair trial and fair consideration on that issue?
Juror Lennie raised his hand. The court asked the juror his thoughts on this issue. Juror Lennie responded:
Well, sir, as far back as I can remember I have not believed in the death penalty. I just think that is something that should not be imposed upon another person.
The trial court then directed the following questions to juror Lennie:
COURT: And, Mr. Lennie, how about you, sir? Do you believe that you could simply automatically vote against the imposition of the death penalty without regard to the evidence that might be developed at the trial itself?
Mr. LENNIE: I can’t conceive of a circumstance where I would vote for the death penalty.
[COURT:] So I take it that as far as you’re concerned that you feel that you would automatically vote for the imposition of the death penalty without any regard to any evidence that might be developed at this trial?
Mr. Lennie: Yes, sir.
(Emphasis added.) While the answer to the last question by the court, containing an obvious lapsus linguae, implies that juror Lennie would automatically vote for the death penalty, when read with the previous questions, it is obviously understood that juror Lennie would be ««able to vote for the death penalty. Without objection, juror Lennie was excused. Defendant argues that there was an insufficient showing that juror Lennie could not follow the law of North Carolina regarding the death penalty.
In Wainwright v. Witt, 469 U.S. 412, 83 L. Ed. 2d 841 (1985), the United States Supreme Court held that a prospective juror may be removed for cause due to his views about the death penalty if those views would “ ‘prevent or substantially impair the perform*379anee of his duties as a juror in accordance with his instructions and his oath.’ ” Id. at 424, 83 L. Ed. 2d at 851 (quoting Adams v. Texas, 448 U.S. 38, 45, 65 L. Ed. 2d 581, 589 (1989)); see also State v. Price, 326 N.C. 56, 388 S.E.2d 84, vacated on other grounds, --- U.S. ---, 112 L. Ed. 2d 7 (1990).
In the case sub judice, juror Lennie explicitly stated that he could not conceive of a circumstance in which he would vote for the death penalty. We find that juror Lennie’s answers clearly show that he could not follow the law or instructions of the trial court if to do so would result in a death sentence. We hold that the trial court did not err in excusing juror Lennie for cause.
V.
[5] Defendant contends that the trial court erred in excusing prospective juror Smith ex mero motu without any showing that juror Smith was not qualified. During voir dire, the trial court asked prospective juror Smith some preliminary questions concerning his knowledge of the case. See N.C.G.S. § 15A-1214(b) (1988). Juror Smith stated that he had read about the killing soon after it happened, and again on the day before jury selection. When asked by the trial judge whether he had formed an opinion as to the guilt or innocence of the defendant, juror Smith denied having formed an opinion but stated: “The one thing that strikes me was about the way the defense was planning to operate struck me as unusual, that there was some change. I read that part and that just struck me as unusual, but as to guilt or innocence, no. That was my feeling. It was just unusual.” After his statement, juror Smith stated he could put out of his mind what he had read about the case. The trial court excused juror Smith after the questioning without objection from either party.
Because the trial judge has the opportunity to see and hear a juror and closely observe his demeanor on voir dire and to make findings based on the juror’s credibility and demeanor, he has discretion to ultimately determine whether the juror could be fair and impartial. State v. Kennedy, 320 N.C. 20, 357 S.E.2d 359 (1987). A trial judge may, in the exercise of his own discretion, excuse a juror even without challenge from either party. State v. Waddell, 289 N.C. 19, 220 S.E.2d 293 (1975), vacated in part on other grounds, 428 U.S. 904, 49 L. Ed. 2d 1210 (1976). A trial judge’s decision as to a juror’s competency to serve is not subject to reversal *380absent a showing of abuse of discretion. State v. King, 311 N.C. 603, 320 S.E.2d 1 (1984).
Here, juror Smith stated that, from what he read, the way in which the defense was planning to operate struck him as unusual. Thus, juror Smith expressed an opinion that was possibly prejudicial to defendant. We find that the trial court’s action in excusing juror Smith did not amount to an abuse of discretion and therefore was not error.
VI.
[6] Defendant further contends that the trial court erred in allowing defendant himself to make the decision to pass juror Carr and to strike juror Covington and in not requiring defense counsel to exercise judgment independent of defendant’s decision in jury selection. Defendant argues that because he was unprepared to represent himself and the trial court made no inquiry regarding this decision, a new trial is required. We disagree.
Tactical decisions at trial, other than the right to testify and plead, are generally left to attorney discretion. Brown v. Dixon, 891 F.2d 490 (4th Cir. 1989), cert. denied, — U.S. —, 109 L. Ed. 2d 545 (1990); State v. Luker, 65 N.C. App. 644, 649, 310 S.E.2d 63, 66 (1983), aff’d as to error, reversed as to harmlessness of error, 311 N.C. 301, 316 S.E.2d 309 (1984) (“[WJhether and how to conduct cross-examinations, what jurors to accept or strike, and what trial motions to make are ultimately the province of the lawyer . . . .”). However, this does not mean that the client has no input into tactical decisions. See Clanton v. Bair, 826 F.2d 1354 (4th Cir. 1987) (trial counsel was found to have performed effectively when he gave a seemingly lucid client great deference in deciding whether to have psychiatric evaluation), cert. denied, 484 U.S. 1036, 98 L. Ed. 2d 779 (1988). In a case filed today, State v. El Amin Ahmad Ali, 329 N.C. 394, 407 S.E.2d 183 (1991), this Court, after a complete analysis of defendant’s sixth amendment right to counsel, concluded that where defense counsel allowed defendant to make a decision not to peremptorily challenge a juror, against the recommendations of both his attorneys, the client’s wishes must control. Contrary to El Amin Ahmad Ali, in the case sub judice, the record reveals that counsel and defendant were not in conflict as to whether to pass or strike these jurors, but simply that defense counsel gave deference to his client’s wishes.
*381In the matter now before the Court, the questions asked of juror Carr revealed that he knew the prosecutor in high school but not well; that he was middle aged, attended church, and worked at Burroughs Wellcome; and that he would consider either life imprisonment or the death penalty, depending on the circumstances of the crime, but that he would have to listen to all of the evidence. After defense counsel passed juror Carr because his client liked him as a prospective juror, the trial court asked defendant the following:
[COURT:] Your lawyer has advised you that while he has [the] right to simply make that decision[,] he has told me, as I understand it, that he is going to pay great attention and consult with you as to- each and every juror, and I’ve noticed him doing that, and so your wishes will be followed pretty much since this is your trial. Is that pretty much correct?
Mr. McDowell: Yes, sir.
Here, defendant acknowledged that his attorney had the right to make the decision regarding jury selection. We find that defense counsel, simply by consulting with defendant regarding potential jurors, did not relinquish his authority as “attorney” but merely gave deference to his client’s wishes in making his tactical decision to pass juror Carr.
Defendant also complains that defense counsel simply excused another juror, Covington, without questioning her. Defense counsel stated that he was excusing the juror because defendant’s family had some reservations about this juror. Defense counsel further remarked that defendant was “emphatic” about excusing juror Covington, although it would be defendant’s last peremptory challenge. The decision not to question juror Covington does not show a failure to act as counsel, as the State had already extensively questioned the juror. The questions posed by the State were sufficient to give defense counsel enough information to make an informed decision. We find that defense counsel acted within the range of competent counsel in excusing the juror without questioning her.
In both instances, defendant has failed to show that defense counsel was ineffective in giving deference to defendant’s wishes during jury selection. Although defense counsel took defendant’s feelings into consideration, he did not abdicate his role as effective *382counsel. We find that the trial court did not err in permitting defendant to give input into the voir dire decision-making process and that defendant was not denied effective assistance of counsel. Cf. State v. El Amin Ahmad Ali, 329 N.C. 394, 407 S.E.2d 183 (defendant not denied effective assistance of counsel where defendant made a decision to accept a juror, against the recommendations of both his counsel); State v. Davis, 101 N.C. App. 12, 398 S.E.2d 645 (1990) (not prejudicial error, if error at all, to allow a criminal defendant to call a witness over the recommendation of his attorney). This assignment of error is without merit.
Guilt Phase Issues
VII.
[7] Defendant contends that the trial court erred in allowing him personally to make the decision whether to present any psychiatric evidence at the guilt phase. We disagree. Defense counsel gave notice on the first day of trial that he intended to introduce expert testimony on whether defendant had the requisite mens rea for the crimes. Dr. Brad Fisher, a clinical psychologist, was available to testify for defendant and to present evidence on the issue. After reviewing the expert’s testimony presented at the sentencing proceeding, defendant argues that the evidence would have cast doubt during the guilt phase as to whether defendant formed the intent to kill after premeditation and deliberation.
At the close of defendant’s evidence at the guilt phase, the question arose as to whether defendant would present any psychiatric “defense.” Defense counsel addressed the court:
Your Honor, at this time that is the extent of our evidence. I would like to, at this time, request the court . . . obviously the defendant at this time has a choice to take the stand on his own behalf. And I would like the Court to inquire and put on the record what he’s indicated to me his desires are which are not to take the stand and not to put on any further evidence.
(Emphasis added.) The trial court then addressed defendant personally:
COURT: And as to the offering of other evidence besides yourself, your lawyer has talked to you about that?
A: Yes. sir. he has.
*383COURT: All right. There has . . . some mention has been made on a pretrial basis according to . ... made aware by your lawyer that you have seen various psychiatrists in connection with possible testimony in this case. And the possibility that they might offer evidence which might be pertinent or relevant on Phase One as well as Phase Two. You’re [sic] lawyer has gone over that with you, right?
A: Yes, sir.
COURT: And he’s told you the pros and cons of that decision too, is that correct?
A: Yes, sir, he has.
COURT: Has that all been explained in the presence of your parents too?
A: Yes, sir. In the presence of my parents and without my parents. So, I understand what he was talking about.
COURT: And what decisions do you want to make, sir, in regards to calling any other witnesses other than the two that have testified? Do you want any other witnesses to testify here for you in this guilt or innocence phase?
A: Well, I know that there would be a physician that would testify for me. So, he was one but my attorney I don’t think he has anybody else.
COURT: I want to make sure you don’t misunderstand me. A: Not in this phase.
COURT: Okay. This phase . . . deals with guilt or innocence. A: Yes, sir.
COURT: Phase Two if reached deals with life or death. You heard me explain that to all prospective jurors at great length when we had jury selection.
A: Yes, sir, I did.
COURT: And this phase right here deals with guilt or innocence. It’s your own choice that your lawyer will not call a psychiatrist or any other witnesses for you in this phase we’re in right now.
A: Yes, sir. That is correct.
*384It is undisputed that the type of defense to present and the number of witnesses to call is a matter of trial tactics, and the responsibility for these decisions rests ultimately with defense counsel. See Jones v. Barnes, 463 U.S. 745, 77 L. Ed. 2d 987 (1983); Brown v. Dixon, 891 F.2d 490 (4th Cir.). Prior to the trial court’s inquiry of defendant, defense counsel stated, “at this time that is the extent of our evidence.” The record indicates that counsel had made the determination not to call any psychiatric witnesses and then requested that the court enter into the record that defendant knew of his right to testify and present further witnesses. We find that this inquiry did not reveal that the attorney was forgoing his responsibility in determining whether to present psychiatric evidence but only that there was agreement between defendant and his attorney.
VIII.
[8] Defendant next contends that the trial court erred in allowing a witness’ statement to be read to the jury since the statement contained additional material not testified to by the witness at trial. We disagree. In his testimony at trial, the witness, Eric Jeffrey, said defendant asked if Jeffrey and Percell “were down to make money,” to which Mr. Jeffrey replied, “No. No.” The State asked if defendant had not said something else before walking off. Mr. Jeffrey denied that he did, except to call them “chicken.” The State then called Mr. Falcone, Mr. Jeffrey’s attorney. The trial court allowed Mr. Falcone to read to the jury a statement that he took from Mr. Jeffrey concerning the killing. In this statement, Mr. Jeffrey had stated that defendant had also “said he was going to get him some money even if he had to burn somebody.”
This Court has previously held that prior statements of a witness can be admitted as corroborative evidence if they tend to add weight or credibility to the witness’ trial testimony. State v. Coffey, 326 N.C. 268, 389 S.E.2d 48 (1990); State v. Ramey, 318 N.C. 457, 349 S.E.2d 566 (1986). New information contained within the witness’ prior statement, but not referred to in his trial testimony, may also be admitted as corroborative evidence if it tends to add weight or credibility to that testimony. Id. However, the State cannot introduce prior statements which “actually directly contradicted . . . sworn testimony.” State v. Burton, 322 N.C. 447, 451, 368 S.E.2d 630, 632 (1988). The witness’ trial testimony that defendant had said nothing else after calling him “chicken,” when the pretrial *385statement detailed the additional comment, is not the type of contradiction that would render the pretrial statement inadmissible. Cf. State v. Howard, 320 N.C. 718, 360 S.E.2d 790 (1987). We find that witness Jeffrey’s statement to his attorney did not contradict his trial testimony and was consistent with and strengthened the events testified to at trial. We hold that the trial court did not err by allowing the statement to be read to the jury by Jeffrey’s attorney.
IX.
[9] Defendant contends that he was denied the effective assistance of counsel when his attorney conceded his guilt to the jury. We disagree and find that the inquiry conducted by the trial court and counsel on the record with defendant was sufficiently specific to meet the requirements set forth in State v. Harbison, 315 N.C. 175, 337 S.E.2d 504 (1985), cert. denied, 476 U.S. 1123, 90 L. Ed. 2d 672 (1986). When defense counsel was about to make his closing argument at the guilt phase, the trial court addressed defendant:
Now, you have entered a plea of not guilty in this case. Do you understand that?
[Defendant]: Yes, sir.
COURT: Now, under the case law your lawyer cannot argue to this jury anything other than flat not guilty unless you specifically authorize him to say something else. In other words, if it is your secret hope that they convict you of second degree murder and not first degree murder, if it’s your secret hope that something else will happen other than flat not guilty, you’re going to have to specifically authorize your lawyer to argue that to the jury.
Because unless you specifically authorize it, he can only argue to this jury that they should turn you loose on everything across the board. The case law squarely says that . . . pleading guilty, in other words, without you filling in a transcript of plea, for him to argue anything by way of a lesser included offense to this jury. I don’t care what you do, I care less, but it’s going to be on the record whatever decision you want to make about your lawyers [sic] argument.
Do you understand all the things I told you?
[Defendant:] Yes, sir.
*386PEFENSE COUNSEL]: I will review it with him again, Judge.
COURT: And what’s more, if, during your lawyers [sic] argument, you find he’s exceeding his authority from you, you better raise your hand and I’ll stop him and I’ll send the jury out so we can make sure the only arguments to the jury is [sic] within the authority you granted.
The court then informed defense counsel that “unless I hear otherwise from him, unless he raises his hand, I’m going to assume that whatever you say to this jury is what he’s authorized you to say.”
During his argument, defense counsel admitted that defendant shot Mrs. Gillie. He then conceded that defendant intentionally fired into an occupied vehicle. Defense counsel argued that defendant’s statement is that he “shot in the car, didn’t realize the woman was there or hit her and [he] kept shooting.” He continued to argue that defendant shot the pistol in order to show his “manhood.” Defendant now argues that although the lawyer, at one point, argued that the correct punishment should be involuntary manslaughter, he conceded all the elements of first-degree murder on two theories.
After the argument in which certain concessions were made, the court asked defendant:
I need to inquire of the defendant. Did your lawyer argue to the jury what you wanted him to argue?
[DEFENDANT]: Yes, sir, he did.
COURT: Did he say anything to the jury[,] anything you didn’t want him to tell or didn’t authorize him to [do]?
[Defendant]: No, sir, he didn’t.
This Court has held that any concession of a client’s guilt absent a consent by defendant to do so constitutes ineffective assistance of counsel per se. State v. Harbison, 315 N.C. 175, 337 S.E.2d 504 (relying on Earl Wayne Wiley v. Sowders, 647 F.2d 642 (6th Cir.), cert. denied, 454 U.S. 1091, 70 L. Ed. 2d 630 (1981)). In a subsequent opinion in Elmer Lee Wiley v. Sowders, 669 F.2d 386 (6th Cir. 1982), the Sixth Circuit Court of Appeals clarified its earlier holding, concluding that “an on-the-record inquiry by the trial court to determine whether a criminal defendant has consented to an admission of guilt during closing arguments represents the preferred practice. But we did not hold in Wiley, [647 F.2d *387642,] and we do not now hold, that due process requires such a practice.” 669 F.2d at 389. This Court has previously declined to set out what constitutes an acceptable consent by a defendant in this context. However, we have remanded a case to the superior court for an evidentiary hearing for the sole purpose of determining whether defendant knowingly consented to trial counsel’s concessions of defendant’s guilt to the jury. State v. Thomas, 327 N.C. 630, 397 S.E.2d 79 (1990).
In the case sub judice, the trial court informed defendant of the need for his authorization and was told on the record that counsel and defendant had discussed the arguments. The trial court then gave defendant instructions on an unobtrusive way to stop any argument which went beyond the scope of defendant’s grant of authority. Finally, after the argument, defendant expressly stated that the attorney had said what he had wished him to say. We find that defendant’s consent to his attorney’s argument was in compliance with the requirements of Harbison.
Where a knowing consent to such an argument has been demonstrated, as in the case at bar, the issue concerning ineffective assistance of counsel should be examined pursuant to the normal ineffectiveness standard set forth in Strickland v. Washington, 466 U.S. 668, 80 L. Ed. 2d 674, reh’g denied, 467 U.S. 1267, 82 L. Ed. 2d 864 (1984), and State v. Braswell, 312 N.C. 553, 324 S.E.2d 241 (1985). The circumstances of this case indicate that the attempt by defense counsel to admit matters demonstrably proved but to negate the one charge that would be the foundation for the aggravating circumstance during the sentencing phase was reasonable trial strategy. Here, defendant admitted in a voluntary pretrial statement that he fired the shots which killed Mrs. Gillie. Defendant stated he did not intend to hurt anyone, but the “accident” claim in his admission was contradicted by the evidence. To negate the attempted armed robbery charge, defense counsel was forced to call a witness who stated defendant intended to “burn” someone to prove his manhood but had said nothing about robbery. Given these facts, it is arguable that defense counsel made a strategically reasonable argument.
Defense counsel admitted that “we came in this courtroom and pled not guilty as a procedural matter” and went on to state “[w]e’ve not tried to deceive you or play the shell game with you or try to say someone else did it.” Counsel admitted that defend*388ant’s “evidence shows you that, in fact, [defendant] did, in fact, go to the back of the Gospel Center . . . and shot Doris Gillie.” He also stated, “I’m not going to stand up here and argue . . . [that] you can’t find from the facts presented in this court, [that] you shouldn’t find[,] that [defendant] shot into that occupied vehicle.” He noted that, if defendant’s statement were believed, “he’s guilty of manslaughter.” Defense counsel noted other evidence and said, if believed, “then I guess you can find first degree murder.” We find that the argument was a reasonable tactical decision by defense counsel and hold that defense counsel was not ineffective when he, with defendant’s consent, conceded defendant’s guilt to particular aspects of the crimes.
X.
[10] Defendant contends that the trial court erred in its instructions to the jury on premeditation and deliberation because the instruction allowed the jury to convict defendant on theories not supported by the evidence. We disagree. The court listed the evidentiary factors from which the jury could infer premeditation and deliberation to include lack of provocation, infliction of lethal wounds after the victim was made helpless, and grossly excessive force.
Each factor upon which the jury is instructed as circumstantial proof of premeditation and deliberation must be supported by competent evidence. State v. Zuniga, 320 N.C. 233, 357 S.E.2d 898, cert. denied, 484 U.S. 959, 98 L. Ed. 2d 384 (1987). However, this Court has held that the appropriate standard for review for unobjected-to instructions, as in the case at bar, is plain error. State v. Oliver, 309 N.C. 326, 307 S.E.2d 304 (1983). We find that, when viewed in the light most favorable to the State, there is sufficient evidence to support submitting each of these factors.
First, as to the evidence on the lack of provocation, the record does not reflect any showing whatsoever of provocation by Mrs. Gillie. Defendant’s admission concerning shooting this stranger did not suggest that she was in any way argumentative or confrontational. See State v. Jackson, 317 N.C. 1, 343 S.E.2d 814 (1986), vacated on other grounds, 479 U.S. 1077, 94 L. Ed. 2d 133 (1987). Second, the evidence showing that one shot, then a series of three shots, fired into a vehicle while Mrs. Gillie sat, strapped into the driver’s seat, is sufficient to show the infliction of lethal blows after the victim was killed or rendered helpless. State v. Barbour, 295 N.C. 66, 243 S.E.2d 380 (1978). Finally, the evidence is con*389sistent with excessive brutality in firing a disabling shot into the victim and then, as she slumped defenseless, shooting at her three more times, striking her at least once. State v. Forrest, 321 N.C. 186, 362 S.E.2d 252 (1987). We hold that the trial court correctly instructed on premeditation and deliberation.
XI.
[11] Defendant contends that the trial court erred in denying his motion to dismiss the charge of attempted armed robbery due to the insufficiency of the evidence. We agree and therefore vacate the conviction of attempted robbery with a dangerous weapon.
The motion to dismiss must be allowed unless there is substantial evidence of each element of the crime charged. State v. Brown, 310 N.C. 563, 313 S.E.2d 585 (1984). Attempted armed robbery is the unlawful attempted taking of personal property from another by use of a firearm or other dangerous weapon. See State v. Smith, 300 N.C. 71, 265 S.E.2d 164 (1980). “Substantial evidence is evidence from which any rational trier of fact could find the fact to be proved beyond a reasonable doubt.” State v. Sumpter, 318 N.C. 102, 108, 347 S.E.2d 396, 399 (1986). The evidence must be viewed in the light most favorable to the State, and the State is entitled to every reasonable inference that is drawn therefrom. State v. Earnhardt, 307 N.C. 62, 296 S.E.2d 649 (1982). However, “[e]vidence is not substantial if it arouses only a suspicion about the fact to be proved, even if the suspicion is strong”’ State v. Reese, 319 N.C. 110, 139, 353 S.E.2d 352, 368 (1987).
The State relies upon the testimony of Eric Jeffrey and Lee Percell, both of whom were also charged in connection with these crimes, to support the attempted armed robbery charge. Both of these witnesses testified to defendant’s possession of the pistol. However, the evidence of defendant’s intent provided by these witnesses is insufficient to support a reasonable inference of attempted armed robbery. In a pretrial written statement to his lawyer which was admitted into evidence for corroborative purposes, Jeffrey said that defendant had stated, “He was going to get him some money even if he had to burn somebody.” According to Mr. Jeffrey at trial, defendant only asked him and Percell if they were “down to make money.” When Jeffrey replied no, defendant called him a “pussy” and a “chicken.” Jeffrey said he could be that. Percell started laughing; as defendant waved the pistol in Jeffrey’s face, defendant demanded to know why Percell was *390laughing. Jeffrey’s testimony about “money” was contradicted by Mr. Percell, who testified that defendant had stated he was going to “burn” somebody but said nothing about robbery. Additionally, Mrs. Gillie’s purse was left undisturbed on the front seat of her car, which tends to contradict the State’s theory that defendant killed Mrs. Gillie in an unsuccessful attempt to take her purse. Even viewing the evidence in the light most favorable to the State, the evidence only supports the theory that defendant was attempting to prove his manhood but is insufficient to support a reasonable inference of defendant’s guilt of armed robbery. We find that the record is insufficient to show more than a suspicion that defendant attempted to rob Mrs. Gillie. We hold that the trial court erred in denying defendant’s motion to dismiss the charge of attempted robbery with a dangerous weapon and therefore vacate this conviction.
Penalty Phase Issue
XII.
[12] Finally, we address defendant’s contention that the trial court erred in submitting the aggravating circumstance in the capital sentencing phase that the killing was committed during an attempt to commit a robbery with a dangerous weapon. We agree and must therefore vacate the sentence of death and impose a sentence of life imprisonment.
The sole aggravating circumstance submitted to the jury during the sentencing phase was that the murder “was committed while defendant was engaged in an attempt to commit robbery with a dangerous weapon.” Because there was insufficient evidence to support defendant’s conviction for attempted armed robbery, we find that there was insufficient evidence to support this aggravating circumstance. The sentence of death shall be vacated and a sentence of life imprisonment imposed in lieu thereof, where, as in the case sub judice, the record does not support the jury’s findings of any aggravating circumstance upon which the sentencing court based its sentence of death. N.C.G.S. § 15A-2000(d)(2) (1988); State v. Hamlet, 312 N.C. 162, 321 S.E.2d 837 (1984).
In conclusion, we find no error in defendant’s conviction of discharging a firearm into occupied property or in defendant’s conviction of first-degree murder. Judgment is vacated in the attempted robbery with a dangerous weapon conviction. Additionally, the *391death sentence is vacated, and defendant is hereby sentenced to imprisonment in the State’s prison for the remainder of his natural life. Defendant is entitled to credit for days spent in confinement prior to the date of this judgment. The Clerk of Superior Court, Durham County, shall issue a commitment accordingly.
87CRS20386, discharging a firearm into occupied property: No error;
88CRS18602, attempted robbery with a dangerous weapon: Vacated;
87CRS20381, first-degree murder: Guilt-innocence determination phase: No error; Sentencing phase: Death sentence vacated and sentence of life imprisonment imposed.
