delivered the opinion of the court:
On November 2, 1988, defendant Nancy Rish was convicted by a *1108jury of first-degree murder and aggravated kidnaping. She was sentenced to a term of natural life imprisonment for murder and a concurrent 30-year term for kidnaping. This court affirmed defendant’s convictions and sentences on direct appeal. People v. Risk, 208 Ill. App. 3d 751, 566 N.E.2d 919 (1991). Defendant then filed a postconviction petition which, along with a subsequent amended petition and two supplemental petitions, raised 16 separate claims. Twelve of the claims were dismissed at the second, pleading, stage. The remaining four claims proceeded to the third stage for an evidentiary hearing and, ultimately, were also dismissed. Defendant appeals from the denial of eight of her claims, seven of which were dismissed without an evidentiary hearing. We affirm in part, reverse in part, and remand.
FACTS
A detailed recitation of the evidence was set forth in our decision on direct appeal of this case. See Risk, 208 Ill. App. 3d at 754-67, 566 N.E.2d at 921-30. We therefore relate only those facts necessary to a general understanding of the case and the issues presented.
On September 2, 1987, Stephen B. Small was kidnaped and a ransom demand was sent to his home. Small’s sister called the police, who immediately initiated an investigation. The investigation focused on Danny Edwards and the defendant, who lived together in a townhouse in Bourbonnais.
On September 4, a search warrant was executed for the townhouse. That evening, Edwards led the police to a rural area where Small’s body was recovered. It appeared that Small had been placed in a wooden box which had been fitted with a PVC pipe designed to give him air for 24 to 48 hours. The box also contained a light connected to an automobile battery, a one-gallon jug of water, candy bars, gum, and a flashlight. Small’s wrists were handcuffed and the box was buried. The coroner later determined that his death was caused by “asphyxia due to suffocation.”
That same night, the police arrested defendant and held her at the station for questioning. Defendant requested a specific attorney, J. Scott Swaim, who had previously represented her, and she was given an opportunity to obtain his counsel. The defendant did not know that Swaim was friends with the victim. The two had socialized at dinner parties and entertained together on several occasions. However, Swaim did not inform defendant of his friendship with Small prior to or at any time after undertaking representation.
For the next four days, between September 4 and September 8, the police questioned defendant with counsel present. Eight statements were elicited concerning her knowledge and actions in the early *1109days of September. None of the statements was totally consistent with any other.
On October 1, defendant was charged by indictment with first-degree murder and aggravated kidnaping for her alleged role in Small’s death. On November 2, 1988, defendant was tried by a jury. No direct evidence was presented linking her to the kidnaping or death of Small. However, the State was able to enter defendant’s eight inconsistent statements into evidence. Witnesses were also presented who testified that they had seen her at various times with Edwards when he was purchasing some items that were ultimately found with Small’s body. Other witnesses reported that they had observed her at various related locations during the course of the kidnaping and ransom calls. Lastly, the State submitted evidence that Edwards had used their garage to build the box in which Small’s body was found. The jury found defendant guilty on both counts, and the trial court sentenced her to a term of natural life imprisonment and a concurrent 30-year term.
After this court affirmed defendant’s convictions and sentences and her petition for leave to appeal to the supreme court was denied, defendant filed a postconviction petition. Following a substitution of counsel, a 12-claim amended petition was submitted. A separate supplemental petition was also filed, adding two additional claims. The circuit court held an evidentiary hearing on four of the claims. Ultimately, all 14 of the claims were dismissed.
Defendant then filed a second supplemental petition, raising two more claims, but these were also dismissed without an evidentiary hearing. Defendant’s motion for reconsideration was denied.
On appeal, defendant challenges the dismissal of eight of her post-conviction claims, arguing them as four issues: (1) whether she was denied due process because the prosecutor presented allegedly false contentions to the jury; (2) whether the trial court erred in finding that two discovery violations were not material within the meaning of Brady v. Maryland, 373 U.S. 83, 10 L. Ed. 2d 215, 83 S. Ct. 1194 (1963); (3) whether claims of ineffective assistance of counsel at custodial interrogation were inappropriately dismissed at the pleading stage; and (4) whether defendant is entitled to sentencing relief pursuant to Apprendi v. New Jersey, 530 U.S. 466, 147 L. Ed. 2d 435, 120 S. Ct. 2348 (2000).
ANALYSIS
The Post-Conviction Hearing Act (Act) (725 ILCS 5/122 — 1 et seq. (West 2000)) provides a three-step process for adjudication of petitions for postconviction relief. At the first stage, the circuit court does *1110not decide the petition on the merits; instead, without input from the State or further pleadings from the defendant, the court determines if the petition presents the gist of a claim for relief, that is, whether the petition contains sufficient facts upon which a meritorious constitutional claim could be based. See People v. Gaultney, 174 Ill. 2d 410, 675 N.E.2d 102 (1996). At this first stage, “all well-pleaded facts that are not positively rebutted by the original trial record are to be taken as true.” People v. Coleman, 183 Ill. 2d 366, 385, 701 N.E.2d 1063, 1073 (1998).
If the court does not dismiss the petition at the first stage, it will, in the second stage, appoint counsel to represent an indigent defendant who requests legal assistance, and counsel will have an opportunity to amend defendant’s postconviction petition. See 725 ILCS 5/122 — 4 (West 2000). The State may then file a motion to dismiss, and the court will determine whether an evidentiary hearing on the merits of the defendant’s petition is warranted. See 725 ILCS 5/122 — 5 (West 2000). A defendant is not entitled to an evidentiary hearing as a matter of course; it is required only when the allegations of the petition, supported where necessary by the trial record and affidavits, make a substantial showing of a constitutional violation. People v. Ward, 187 Ill. 2d 249, 255, 718 N.E.2d 117, 123 (1999); People v. Henderson, 171 Ill. 2d 124, 140, 662 N.E.2d 1287, 1296 (1996). In making this determination, all well-pleaded facts in the defendant’s petition and any accompanying affidavits are taken as true. People v. Caballero, 126 Ill. 2d 248, 259, 533 N.E.2d 1089, 1091 (1989). Mere conclusions, however, are insufficient to require a hearing under the Act. Coleman, 183 Ill. 2d at 381, 701 N.E.2d at 1072. The evidentiary hearing and a determination on the merits is the third and final stage of postconviction proceedings. See 725 ILCS 5/122 — 1 through 122 — 8 (West 2000); see also People v. Patton, 315 Ill. App. 3d 968, 735 N.E.2d 185 (2000). In considering plaintiffs appeal, we have divided our analysis of defendant’s postconviction claims into two separate sections, according to the appropriate standards of review.
Claim Subject to Deferential Review
Brady Violation
We first consider the denial of count III, alleging a violation of Brady v. Maryland, 373 U.S. 83, 10 L. Ed. 2d 215, 83 S. Ct. 1194 (1963). Since this count survived to the third stage for an evidentiary hearing, we will not disturb the circuit court’s ruling unless it is manifestly erroneous. See Coleman, 183 Ill. 2d at 385, 701 N.E.2d at 1074.
Defendant asserts that the prosecution committed a Brady viola*1111tion when it presented James Witvoet as an identification witness, but failed to disclose that criminal proceedings were pending against him. At the time he testified, two charges of illegal operation of a migrant labor camp were pending against Witvoet in Kankakee County. Each count was a petty offense, with a minimum fine of $100 and a maximum fine of $500. Defendant maintains that the State’s omission was prejudicial to her case because the criminal charges could have been used to impeach Witvoet’s testimony.
We do not find defendant’s assertion tenable. Although the government is obligated to turn over evidence in its possession that is favorable to the accused, the evidence must be material to guilt or punishment. See Brady, 373 U.S. at 87, 10 L. Ed. 2d at 218, 83 S. Ct. at 1196-97. Evidence is material only if there is a reasonable probability that, had it been disclosed to the defense, the result of the proceeding would have been different. A “reasonable probability” is a probability sufficient to undermine confidence in the outcome. Pennsylvania v. Ritchie, 480 U.S. 39, 57, 94 L. Ed. 2d 40, 57, 107 S. Ct. 989, 1001 (1987).
In this case, the prosecutor’s failure to disclose Witvoet’s pending criminal charges was not a Brady violation because the criminal charges were not material to defendant’s guilt. Witvoet testified that he was driving with another person in an area near the crime scene when he saw a van similar to one owned by Edwards. Witvoet saw two people in the van: a male with dark hair and another individual with dishwater blonde hair, similar to defendant’s. However, Witvoet was unable to say whether the blonde passenger was a man or a woman.
As the circuit court noted, when a witness has a pending criminal charge, the concern is that he may testify falsely in return for leniency. Witvoet first reported his observations to the police in September of 1987; he was not charged criminally until 10 months later, in July of 1988. His testimony at trial was consistent with his earlier report to the police. There is no indication that Witvoet altered his testimony to gain favor with the State. Indeed, Witvoet testified at the postconviction hearing that the charges did not affect his testimony because he knew that the State had mistakenly charged him instead of his father, James Witvoet, Sr. Witvoet believed that the charges would ultimately be dismissed, and they were, in January of 1989, for that reason. There were no plea negotiations with the State’s Attorney prior to dismissal.
Of course, the relevant question is not whether Witvoet’s testimony was affected by the criminal charge, but whether the result of the trial was undermined by defendant’s inability to impeach Witvoet with those charges. Given the lack of gravity of the charges,
*1112their timing, Witvoet’s professed lack of concern, and the absence of any plea bargain, we believe the impeachment value of the charges was extremely low. Accordingly, we find that the circuit court’s ruling that the State’s discovery violation was not material was not manifestly erroneous. The denial of count III of defendant’s postcon-viction petition is affirmed.
Claims Subject to De Novo Review
The following seven claims will be reviewed de novo, since no deference is extended to the trial court when no evidentiary hearing has been held. Coleman, 183 Ill. 2d at 388-89, 701 N.E.2d at 1075.
Ineffective Assistance of Counsel Defendant challenges the dismissal of count I of her petition, which alleged that her right to counsel was violated during custodial interrogation. She complains that her attorney at the interrogation, J. Scott Swaim, had an interest in the case that was adverse to her own. Specifically, she claims that Swaim was a close friend of the victim, Stephen Small. In addition, Swaim had been the attorney for a Kankakee police officer involved in the case, Detective Robert Anderson. These two conflicts, the defendant argues, motivated Swaim to allow her to give eight inconsistent statements over the course of the four-day interrogation, statements that were later used by the prosecution at trial.
The defendant argues that both the fifth amendment to the United States Constitution (U.S. Const., amend. V) and article I, section 10, of the Illinois Constitution (Ill. Const. 1970, art. I, § 10) entitle her to conflict-free counsel during custodial interrogation. The circuit court, noting the limited nature of counsel’s function under the fifth amendment, found no violation, stating:
“The point of the [flifth amendment, including the Miranda warnings, is to prevent police coercion of criminal suspects. It is clear to the [c]ourt on the record before it, that Ms. Rish was advised of her Miranda warnings, including her right to remain silent and her right to stop the questioning at any time. Swaim was with her throughout, police questioning, stopping it occasionally and instructing her not to answer some questions. This would fulfill the purpose of the [flifth amendment — to insure the [defendant knew her rights, and to insure that any statements she made were the product of her voluntary choice and not the product of police coercion. The [c]ourt therefore finds that there was no [flifth amendment violation here.”
We agree that a defendant’s right to counsel under the fifth amendment does not include the same guarantee of effective assistance *1113of counsel contained in the sixth amendment but, rather, only protects a defendant from coerced confession. However, we believe that the Illinois Constitution entitles those subject to custodial interrogation the right to conflict-free counsel. Ill. Const. 1970, art. I, §§ 2, 10. In Illinois, the right to the assistance of counsel has historically been afforded a certain degree of judicial solicitude and due process protection. People v. McCauley, 163 Ill. 2d 414, 441, 645 N.E.2d 923, 937 (1994). “The State’s due process guarantee [citation] provides the general basis for an accused’s right to the assistance as well as presence of counsel during any custodial interrogation.” (Emphasis added.) McCauley, 163 Ill. 2d at 441, 645 N.E.2d at 937. This right has not been found satisfied by the mere formality of the appointment of an attorney, but has required effective representation. McCauley, 163 Ill. 2d at 442, 645 N.E.2d at 937. “[D]ue process of law requires that an accused shall be given the benefit of counsel.” (Emphasis in original.) McCauley 163 Ill. 2d at 441, 645 N.E.2d at 937.
Effective assistance of counsel has long been recognized to include the right to the undivided loyalty of counsel, free from conflicting interests or inconsistent obligations. People v. Walker, 253 Ill. App. 3d 93, 107, 624 N.E.2d 1353, 1363 (1993). Although this right can be waived, it is well settled that a defendant must first be adequately informed of a conflict’s significance before the right will be deemed to have been waived. See People v. Coleman, 301 Ill. App. 3d 290, 301, 703 N.E.2d 137, 145 (1998).
In this case, the defendant alleges she was denied information material to a knowing and intelligent decision to waive her right to the presence of an attorney wholly committed to her interests. She claims that her attorney offered no explanation to ensure her understanding of the potential significance of his personal relationship with Small and that, in fact, defense counsel did not disclose this relationship at all during the four days defendant was subject to police interrogation.
“Due process essentially requires ‘fairness, integrity, and honor in the operation of the criminal justice system ***.’ ” McCauley, 163 Ill. 2d at 441, 645 N.E.2d at 937, quoting Moran v. Burbine, 475 U.S. 412, 467, 89 L. Ed. 2d 410, 450, 106 S. Ct. 1135, 1165 (1986) (Stevens, J., dissenting, joined by Brennan and Marshall, JJ.). In a situation such as this one, where counsel for a criminal suspect possibly labors under a serious conflict of interest, one which potentially places him in a position adverse to that of his client, the fairness that is fundamental to our system of justice is suspect. The defendant had a right to expect that her requested counsel was acting completely in her interests. Such was not necessarily the case here. The allegations *1114raised on the pleadings are sufficient to state a claim for ineffective assistance under Illinois due process guarantees. It was improper for the trial court to dismiss the claim without first holding an evidentiary hearing.
The trial court must hold a hearing on the claim raised by the defendant and should apply the test for ineffective assistance developed in Strickland v. Washington, 466 U.S. 668, 80 L. Ed. 2d 674, 104 S. Ct. 2052 (1984). In that test, the defendant first must establish that her counsel’s performance was so deficient that the representation fell below an objective standard of reasonableness. Strickland, 466 U.S. at 688, 80 L. Ed. 2d at 693, 104 S. Ct. at 2064. She also must demonstrate that there is “a reasonable probability that, but for counsel’s unprofessional errors, the result of the proceeding would have been different.” Strickland, 466 U.S. at 694, 80 L. Ed. 2d at 698, 104 S. Ct. at 2068. We adopt this test for ineffective assistance claims under the Illinois Constitution since many courts have substantial experience applying it, from its wide use as the standard for ineffective assistance under the sixth amendment to the United States Constitution.
We find that the circuit court erred in its dismissal of count I of defendant’s postconviction petition. Accordingly, we reverse and remand for an evidentiary hearing and for the application of the Strickland test. We do so despite the fact that, in dismissing count I, the circuit court made an alternative finding that if Strickland was applicable, attorney Swaim was not ineffective. That determination was made without benefit of an evidentiary hearing. Defendant is entitled to such a hearing because her attorney’s undisclosed conflict of interest constitutes a substantial showing of a constitutional violation under the Act.
Defendant also challenges the circuit court’s dismissal of counts II and XIII of her postconviction petition. Those counts involved allegations of ineffective assistance because of her trial counsel’s failure to raise a sixth amendment claim of custodial, preindictment ineffective assistance of counsel at trial and again on direct appeal. The circuit court dismissed both counts, finding the absence of a sixth amendment right to counsel at that time. Defendant claims error, asserting that adverse judicial proceedings had begun because of the State’s decision to prosecute her shortly after she was taken into custody.
We reject this challenge. The sixth amendment states in relevant part that “[i]n all criminal prosecutions, the accused shall enjoy the right to *** have the Assistance of Counsel for his defence.” U.S. Const., amend. VI. However, the sixth amendment does not attach *1115until at or after the initiation of adversarial judicial proceedings, whether by way of a formal charge, prehminary hearing, indictment, information, or arraignment. People v. Garrett, 179 Ill. 2d 239, 247, 688 N.E.2d 614, 618 (1997). In this case, the circuit court appropriately dismissed defendant’s sixth amendment claim, because the right had not yet attached. None of the identified adversarial judicial proceedings had yet begun.
We also reject defendant’s argument that adverse judicial proceedings had already begun due to the State’s implementation of a decision to prosecute her. We acknowledge that the level of prosecutorial involvement may be considered in determining whether a defendant’s sixth amendment right to counsel has attached. See Garrett, 179 Ill. 2d at 248, 688 N.E.2d at 618. However, we do not find this argument meritorious, because defendant has not cited to any portion of the record which supports her allegation that the prosecution had reached a decision to prosecute her shortly after she was taken into custody. Although she directs our attention to a transcript of Sergeant William Willis in which he stated that the State’s Attorney’s office was involved in the preparation of the search warrant affidavit, defendant provides no authority to support the proposition that this conduct would constitute a level of prosecutorial involvement justifying the attachment of the sixth amendment right to counsel. We affirm the dismissal of counts II and XIII of defendant’s postconviction petition.
Due Process
Defendant also challenges the dismissal of her claim (count IV) that prosecutorial misconduct resulted in a violation of due process. At trial, the prosecutor asserted during his closing arguments that defendant had lied in her testimony. She had testified that Detective Erickson threatened her at the police station immediately following her arrest by asserting that she could potentially receive the electric chair if convicted. The prosecutor claimed that defendant’s story about the incident was a perjured fabrication, because Erickson was not at the police station on the day of her arrest, and he denied having had such a conversation with defendant at any other time or place. However, one year after trial, Illinois State Police Sergeant William Willis stated in a television appearance that he was the officer who had made the “threat” against her while at the station.
Defendant contends that the prosecution’s argument constituted a knowingly false allegation of perjury that violated her due process rights. In support, she asserts that, as a matter of law, any information known by the police is automatically imputed to the prosecution.
Contrary to defendant’s contention, knowledge by police officers is *1116not automatically imputed to the prosecution in a per se manner. Rather, the imputation requires an individualized focus on the factual circumstances. Among the factors to be considered would be the reasonableness of such imputation, whether the failure to transmit such knowledge up the informational chain was inadvertent or intentional, and whether any real prejudice occurred. People v. Robinson, 157 Ill. 2d 68, 80, 623 N.E.2d 352, 358 (1993).
In this case we are uncertain whether Willis’s knowledge should be imputed to the prosecution. One factor weighing against such attribution is that defendant helped to create the problem by misidentifying the maker of the statement as Detective Erickson. As the circuit court noted:
“If [defendant] had correctly identified Sergeant Willis, the State would have confronted him, and the truth would have come out. If she had not identified any one at all, and merely said it was a policeman, the State could then have inquired of everyone involved in the investigation. But when she says it was Detective Erickson and Erickson denies it, there is no obligation on the State to then conduct a further investigation of anybody involved in her questioning. This Court has seen Sergeant Willis testify in court. He is nowhere near the size of Detective Erickson. There is no explanation in the record how the Defendant came to identify the maker of the alleged threat as Detective Erickson.”
On the other hand, because no evidentiary hearing was held, we do not know whether Willis intentionally hid his knowledge from the prosecution, nor do we know whether he told any other officers or investigators about the incident. Under the circumstances, we believe that an evidentiary hearing is necessary. We therefore reverse the dismissal of count IV of defendant’s postconviction petition and remand for such a hearing.
Brady Violation
We next consider defendant’s challenge to the dismissals of counts IX and X of her postconviction petition. Count IX argued that a Brady violation occurred when the State knowingly made a false argument to the jury in its closing arguments regarding her alleged purchase of distilled water. Count X also averred a Brady violation in closing arguments because of the State’s failure to disclose a laboratory report relating to the distilled water.
One week prior to trial, the Illinois State Police forensic science laboratory returned a report to the State’s Attorney’s office that no analysis of the liquid found in the jug next to Small’s body could be done because of possible contamination of the sample by the forensic science laboratory equipment. Defendant asserts that the report would *1117have enabled the defense to impeach the connection between herself and the liquid found in the box where Small had been buried.
We believe the State committed a discovery violation when it failed to hand over the laboratory report to the defendant. Defendant requested the results of any testing pertinent to the case, and the attending forensic scientist was disclosed by the State as a possible witness. However, we find that the State’s failure to divulge the report was not material within the meaning of Brady, because even had the report been divulged, there is no reasonable probability that it would have affected the outcome of the proceedings. See Ritchie, 480 U.S. at 57, 94 L. Ed. 2d at 57, 107 S. Ct. at 1001 (evidence is material only if there is reasonable probability that results of proceeding would have been different).
Three witnesses testified concerning the issue of distilled or bottled water. Linda Forestier, a hardware store clerk, testified that a man and woman similar in appearance to Edwards and the defendant entered the store together on or about August 31, 1987. The woman asked if the store sold distilled water. Forestier replied that it did not and directed the couple to a grocery store. On cross-examination, For-estier was unable to identify the defendant as the woman in the store that day.
Donna Jordan, an employee of Convenience Food Mart in Bour-bonnais, testified that defendant, who was a regular customer, came into the store with a man who asked for bottled water. This occurred between August 29 and September 1, 1987. On cross-examination, Jordan stated that she was not sure that the defendant was in the store on the same night that the man came in to buy the water.
Arlene Bires, a clerk at Ruffin’s Super Value in Aroma Park, testified that on September 3, 1987, Edwards came into the store and bought a few gallons of water and five or six candy bars. The defendant was not with Edwards.
The jug found with Small’s body was not placed into evidence at trial by either party. Although the State informed the jury that some water was found with Small, no connection was ever established between the water the codefendant purchased and the water found in the box. Neither party focused on the water in closing arguments. Given the extremely low probative value of the testimony concerning the water, we do not believe that the State’s failure to disclose the laboratory report had any impact on the trial. Accordingly, we affirm the dismissal of counts IX and X of defendant’s postconviction petition.
Apprendi
Finally, defendant contends that the trial court erred in dismiss’ *1118ing count XVI of her postconviction petition, which argued that her extended-term sentence based on the aggravating factor of exceptionally brutal or heinous behavior indicative of wanton cruelty violated Apprendi v. New Jersey, 530 U.S. 466, 147 L. Ed. 2d 435, 120 S. Ct. 2348 (2000). The circuit court declined to address the merits of her claim, reasoning that Apprendi should not be applied retroactively to cases on collateral review. We agree. Our supreme court recently held in People v. De La Paz, 204 Ill. 2d 426, 791 N.E.2d 489 (2003), that Ap-prendi does not apply retroactively. We therefore affirm the dismissal of count XVI.
CONCLUSION
For the reasons stated above, we affirm the denial of count III of defendant’s postconviction petition and the dismissal of counts II, IX, X, XIII and XVI. We reverse the dismissal of count I, alleging ineffective assistance, and count iy alleging prosecutorial misconduct, and remand for an evidentiary hearing. Affirmed in part and reversed in part; cause remanded.
