delivered the opinion of the court:
During the early morning hours of August 2, 1972, a Chicago police officer, responding to a radio call concerning a battery victim, entered an apartment on the south side of the city. He found a dead man lying in a bed. It was apparent that the cause of death was traumatic injury to the skull and face. In due course, William Tennant (defendant) was indicted for the murder of the deceased. After trial by jury, defendant was found guilty and sentenced to a term of 15 to 30 years. He has appealed to this court.
Defendant has raised three contentions: he was denied due process when the trial court permitted a transcript of the testimony of a deceased witness (Willa Watson) given at a preliminary hearing to be *1036read in evidence; the evidence was not sufficient to prove him guilty beyond a reasonable doubt and the trial court erroneously refused an instruction tendered by defendant pertaining to an admission and instead gave an instruction tendered by the State regarding a confession.
The People contend that the evidence given by Willa Watson at the preliminary hearing was properly admitted; defendant was proved guilty beyond a reasonable doubt and the jury was properly instructed with reference to the statements of guilt made by defendant.
When the officer originally came to the apartment, there was no response to his knock. He left and shortly thereafter received a second call concerning the same addess. He was then admitted to the third floor apartment by Herbert Cross, a blind person. The apartment, originally six rooms, has been modified for use as four sleeping rooms with a common kitchen and bathroom. The front entrance door may be locked but not the rear door. Also, there are no functioning locks on the doors of any of the individual rooms.
It appears from the testimony of the officer that he found the body in one of the rear bedrooms which was ordinarily occupied by defendant. The deceased was lying face up in the middle of the bed. There was blood spattered onto the bed and on the wall. There were traumatic injuries to the head and face. The defendant was then absent. He came in while the officer was speaking to a lady named Willa Watson. She occupied two rooms in the front part of the establishment with Harry Housely. A man named Peter Reeves occupied a room located to the rear.
After the officer had entered the apartment, he awakened Willa Watson and Harry Housely. When Miss Watson appeared she was dressed in a nightgown and her head was bandaged. She identified the deceased.
The officer had a conversation with defendant. When defendant approached, the officer noted some red spots on his clothing and on his shirt near the collar and close to the shoulder. He also saw a red substance near the fly and on the right leg of defendant’s trousers. Upon examination of the bathroom, the policeman found a red substance which he described as being a “blood-type” in the basin. There was also a dress soaking in the bathtub in water which had “a reddish tint.” Watér similarly tinted was found in a small bucket in the bathtub. Willa Watson told him that she had received a head wound earlier in the week and that her dress was stained with blood. After receiving Miranda warnings, defendant stated that he had been at his sister’s apartment. When he returned, he got into his bed and laid down next to the deceased. He then nudged the deceased so that he could request some money for the purchase of wine. Receiving no response, he then looked closely at de*1037ceased and observed his condition. He then got out of bed and called the police. He said that he had made two calls to the police station. At the officer’s request he removed and surrendered his clothes.
The officer then spoke with Peter Reeves who lived in the same flat. In his room the officer noted a piece of metal some 3 feet long leaning against the door of the refrigerator. He gave this piece of metal to the technicians. They dusted it but told him that they could find no fingerprints, although there was a reddish stain on the end portion of the bar. The officer also noted a few drops of a “red substance” on the floor some 3 to 5 feet inside the room occupied by Willa Watson.
Over objection by defendant, the trial court permitted the reading to the jury of a transcript of the testimony given by Willa Watson at a preliminary hearing against defendant, held August 17, 1972. The parties stipulated that Willa Watson died in Chicago on January 3, 1973, before commencement of trial.
She had testified for the State and she was cross-examined by counsel for defendant. Her testimony was that she had known defendant for 6 years but knew the deceased for 6 months. She, defendant and deceased had spent the evening and early morning hours together drinking on the back porch of the apartment. The deceased left the others about 2:30 a.m. At about 3 o’clock she went to bed. At that time she saw the deceased sleeping in defendant’s bed. She was awakened when defendant knocked on her door and asked her if he could come in to get some clothes which she kept for him. She could not estimate when that occurred. Defendant came in, got his things and left, carrying the metal bar. She then heard defendant say “get out of my bed # # with tire addition of an obscenity.
Defendant later reentered her room and threw “the iron pipe” down on her bed or by her bed. He later came back and got the piece of iron once more. It was hers and she had used it to hold the broken door of her refrigerator closed. It was found by the police in the room of Peter Reeves. At the request of the police, she identified the piece of iron as being hers. She stated that it was a part of an iron bed rail, cut to a length of about 2 feet. The cross-examination of this witness by counsel for defendant took approximately 12 pages of the record, while the direct examination took 9 pages. No substantial differences of any kind were developed by the cross-examination.
Two homicide investigators of the police department also came to the apartment that morning. After examination of the scene, they returned to the police station where they took statements from Willa Watson and Peter Reeves. These statements were then typed and signed by the witnesses. That same morning they interviewed defendant. One of the in*1038vestigators gave defendant legal warnings which defendant said that he understood. The investigator further testified that defendant then told him he had not been home all night but he had been at his sister’s home. Defendant then made a statement to the investigator quite similar to that which he had told the first police officer concerning his alleged discovery of the death of deceased.
At defendant’s request, he then left the room unaccompanied to get some water. When he returned, the officer told him that he knew from his investigation that defendant had been in the apartment all evening drinking with the other tenants. After further talk, defendant stated that he would tell the truth and he said that he beat the deceased with the angle iron and killed him. This entire conversation and questioning took approximately 10 or 15 minutes. Aside from deleted expletives, the defendant told the officer that he killed the deceased because he was “picking on him.” The investigator asked defendant if he would repeat that statement to an Assistant State’s Attorney which defendant said he would.
Marshall Weinberg, then an Assistant State’s Attorney, was in private practice when he testified. He testified that he introduced himself to defendant and asked him if the police had advised him of his constitutional rights. After receiving an affirmative answer, the witness again advised defendant of his rights. He asked defendant if he was the one who had struck and killed the deceased and defendant “indicated that he had done it.” He asked defendant why he had killed the man. Defendant responded that the deceased “had taken my food stamps and other things.” The witness testified that apparently defendant and deceased were roommates. Defendant told him in effect that he had occupied the room and that the deceased was an interloper.
In further conversation, the defendant stated that he had struck the deceased with an iron bar. Mr. Weinberg then suggested to defendant that a court reporter be called so that he could repeat his statement and have them written. Defendant then said that before he would sign anything he wished to talk to an attorney. The witness further testified without objection that he then went to his office and made a written memorandum of the statement given him by defendant. Two days later this memorandum was typed by a secretary and signed by the witness. It was exactly the same as his handwritten version. The memorandum was marked as an exhibit. It was the subject of cross-examination by counsel for defendant. The court sustained a defense objection and rejected this exhibit. Additional cross-examination of this witness by counsel for defendant will receive later consideration.
The parties stipulated that if a certain pathologist for the coroner were *1039called he would testify that death of the victim was caused by a skull fracture which resulted in brain laceration.
Evidence for the defense showed that the police laboratory had found that blood of the deceased was type “O”. The same type of blood was present on the bed where the body was found and near the collar of defendant’s shirt. The front of the shirt and defendant’s trousers both showed blood types of “O” and “A” so that these tests were not conclusive. The metal bar above described also had blood types “A” and “O” but predominantly “A” so that it could not be classified as type “O”.
Defendant’s niece, Barbara Hunter, some 17 years old, testified that, commencing midnight of August 1, 1972, defendant visited the home where she lived with her aunt. She stated that defendant had spoken briefly to her and her aunt but had fallen asleep because he had been drinking. When defendant left, at about 4 a.m., the witness was watching a picture on television. She watched Channel 9 and continued her viewing until 6 or 6:30 a.m. The parties stipulated that, if called, personnel from this station would testify that the station “signed off” that morning at 3:10 a.m. plus 30 seconds. The aunt of this witness was in the hospital at the time of trial.
Defendant testified that the angle iron had been used on Willa Watson’s refrigerator. He had helped her close the refrigerator with it before noon on August 1. He did not see it again until it was found in the room of Peter Reeves. Defendant testified that he had worked as a welder but eye surgery had terminated his employment. The parties stipulated that an examination of defendant’s eyes in August of 1972 found that he had glaucoma and the lens of his left eye was gone. The sight of this eye was poor and even with glasses the vision of his right eye was 20/60. On August 2, his glasses had been broken and they were being repaired.
Defendant further testified that he had helped the janitor in the building until about 8 o’clock on the evening of August 1. Some three hours later he walked to his sister’s home and spoke to her and his niece. He dozed off and awakened about 4 a.m., when he left. On the way home he passed a clock near a window which showed 4:15 a.m. At home he lay down in his bed next to deceased. Deceased had stayed with him before as they were friends. He could not see in his room because of the absence of his glasses and because the switch on his room light did not work. He then opened his refrigerator door which gave some light and leaned over close to the face of the deceased. He went over to Willa Watson and asked her about deceased because the face had appeared “wet.” He then called the police twice. When he saw them arrive, he returned to the apartment from where he had gone to use the telephone.
Defendant testified that he had spoken with the police officers and *1040with the State’s Attorney but he denied that he had told any of them that he had struck or killed deceased. The State’s Attorney gave him a paper to sign but he could not read it without his glasses so he refused to sign.
The first point raised by defendant is directed to the propriety of reading to the jury the testimony of the deceased Willa Watson given at the preliminary hearing. We have above summarized this testimony and have shown the extent of the cross-examination.
Defendant’s brief virtually concedes that no rights of a defendant are violated by reading the previous testimony of a deceased witness if “at the preliminary hearing or former trial, the accused had been accorded an adequate opportunity to cross-examine such witness.” (People v. Coburn, 20 Ill.App.3d 60, 63, 313 N.E.2d 270, quoting the general rule from 3 Wharton’s Criminal Evidence § 650, at 371-374 (13th ed. 1973).) Defendant, however, raises the point that cross-examination at a preliminary hearing can never be full and adequate because under Illinois law defense counsel has no right to discovery until after this hearing. (Supreme Court Rule 411, Ill. Rev. Stat. 1973, ch. 110A, R. 411.) If this contention were accepted, testimony of a witness who died after the preliminary hearing could never be used. It seems more logical and reasonable to permit the use of this testimony provided that there was no significant limitation upon the free exercise of the right to cross-examine by counsel. This statement of the rule was approved by the United States Supreme Court in California v. Green, 399 U.S. 149, 165, 166, 26 L.Ed.2d 489, 90 S.Ct. 1930, where the Court noted that the rights of defendant’s counsel were not “significantly limited in any way in the scope or nature of his cross-examination of the witness Porter at the preliminary hearing.” This rule has been firmly adopted in Illinois. For us to review the many decisions which so hold, in addition to Coburn, would be a needless repetition. We find an excellent statement of the rule and a listing of the applicable authorities in the recent decision by this court in People v. Beathea, 24 Ill.App.3d 460, 465, 466, 321 N.E.2d 458.
We find no constitutional problem flowing from the use of the prior recorded testimony. Admission of such testimony in a proper case has long been an exception to the basic constitutional right of confrontation of the prosecution witnesses. (See Barber v. Page, 390 U.S. 719, 722, 20 L.Ed.2d 255, 88 S.Ct. 1318.) Nor can a situation involving a deceased witness be equated with a situation involving a witness who is simply missing. In the latter type of case, the State must prove that it has made an actual and. good faith effort to locate the missing witness. (People v. *1041 Payne, 30 Ill.App.3d 624, 332 N.E.2d 745.) In the case of the deceased witness, we are not concerned with prosecution good faith but simply with a preliminary determination as to whether the defendant has had an ample opportunity to cross-examine the witness as a test of reliability. As pointed out in Beathea, “the testimony of a witness at a preliminary hearing is admissible into evidence at trial when the witness is unavailable without fault on the part of the State and when ample opportunity to cross-examine had existed at the preliminary hearing.” 24 Ill.App.3d 460, 465.
No case has been called to our attention, nor do we believe one exists, holding that an additional duty must be imposed upon the trial court to make a predetermination concerning reliability of the testimony. Following this rule would simply add another and unnecessary burden to the function of the trial court which would be obliged, in every such instance, to conduct a complete trial within a trial with the result dependent directly upon an evaluation of the testimony of the absent witness in connection with all of the other evidence. This task would be far more burdensome than hearings on admission of confessions or identifications both of which can be decided only on testimony pertinent to the specific inquiry. This would be an infringement upon the function of the jury to determine credibility of all of the witnesses.
In the case before us, the cross-examination of the witness Willa Watson at the preliminary hearing was detailed and complete. There was no significant limitation of any kind upon the full and free right of cross-examination as actually exercised by defendant’s counsel at the preliminary hearing. Thus, we are dealing with a situation in which the rights of defendant were not violated by reading the transcript of her testimony to the jury. If we were to adopt the blanket and inflexible ruling of exclusion urged upon us by defendant, the result reached would be contrary to the authorities above noted and to the many cases therein cited.
In considering the sufficiency of the evidence to prove guilt beyond a reasonable doubt, defendant relies upon several collateral contentions. Defendant first points out the alibi evidence supplied by his own testimony and that of his niece. The contention that the State was unable to refute the alibi is not entirely correct as the rebuttal evidence regarding the time that the television station, which defendant’s niece said she was viewing, ended its broadcast, does tend to discredit her testimony. In addition, defendant first told the police that he had been visiting his sister at the time but this is contradicted by his own subsequent confession repeated to a police officer and to an Assistant State’s *1042Attorney. In addition, defendant’s alibi was badly shaken by the testimony of the deceased WiUa Watson regarding his activities in her presence at the time in question.
It is correct that when a defendant has presented proof of an alibi he is not bound to prove this defense beyond a reasonable doubt. The burden of proof remains upon the State to prove the defendant guilty as charged beyond a reasonable doubt. (People v. Brown, 52 Ill.2d 94, 105, 106, 285 N.E.2d 1.) However, there is no obligation on the trier of fact, be it court or jury, to believe alibi testimony. (People v. Jackson, 54 Ill.2d 143, 149, 295 N.E.2d 462.) In addition, the fact that there is alibi evidence which conflicts with the proof adduced by the State does not in itself require that this court reject the verdict of the jury. Despite the presence of alibi testimony in the record, it remains “the function of the jury to make a determination of tire credibility of the alibi witnesses and of the weight to be given to the totality of the testimony.” See People v. Brown, 52 Ill.2d 94, 105, 106.
Defendant next urges that, having failed to call other available witnesses, the State must accept the risk of possible negative inferences being drawn by their failure to do so. It has frequently been held that the State “is not obliged to call every witness who might testify concerning evidence of the crime.” (People v. Farnsley, 53 Ill.2d 537, 545, 293 N.E.2d 600.) This rule is also set forth in People v. Davis, 19 Ill.App.3d 848, 312 N.E.2d 343, cited by defendant. It is conceivable that failure of any litigant to call a designated witness could correctly become the subject of negative inference but it does not appear that such inference was actually made at trial or could properly have been made. Defendant directs this contention at the failure of the State to caH Peter Reeves and the blind man Herbert Cross. There is nothing in this entire record to indicate that Cross had any knowledge of any material fact or was ever questioned on these matters. Reeves, the other witness, made a statement to the police which was disclosed to defendant in the answer to his discovery motion filed by the State. If this statement contained evidence which would have been helpful to defendant, there is no showing that this witness was not readily available to defendant and his address was listed in the discovery response.
Defendant urges that testimony by the former Assistant State’s Attorney was prejudicial to defendant. The State’s Attorney testified on cross-examination by defense counsel regarding the function of the Felony Review Unit to which he was assigned and also expressed the opinion that he would not approve a case for prosecution if it was “other than a good case.” This subject was not brought out or covered in any *1043manner on direct examination. Defendant cites and depends upon cases such as People v. Cepek, 357 Ill. 560, 192 N.E. 573, where the prosecutor made an improper closing argument concerning his opinion of guilt; People v. Adkins, 16 Ill.App.3d 394, 306 N.E.2d 709, which involved a similar situation and People v. Mostafa, 5 Ill.App.3d 158, 274 N.E.2d 846, where a former Assistant State’s Attorney testified on direct examination regarding his opinion as to whether a crime had been committed by a third party. None of these authorities are applicable here.
In the case before us, all of the testimony of the former Assistant State’s Attorney, to which defendant now takes exception, was deliberately and intentionally brought out by defendant at trial. This is conceded in defendant’s reply brief which states that this was expressly brought out by defendant and was “an effective job of revealing the witnesses’ interest in the case.” The cases are numerous in taking the most logical position that “a defendant may not interject an issue into his case and then contend that the bringing of it to the attention of the jury was erroneous.” (People v. George, 49 Ill.2d 372, 379, 274 N.E.2d 26. See also People v. Burage, 23 Ill.2d 280, 282, 283, 178 N.E.2d 389.) The defendant here, as a matter of tactics, himself elected to bring the alleged bias of the witness before the jury by this cross-examination. Now that this strategy has failed, defendant is not in position to make a complete turnabout and attempt to benefit from alleged error which he himself purposely created. People v. Dixon, 37 Ill.2d 416, 226 N.E.2d 608.
Considering the general argument regarding proof of guilt beyond a reasonable doubt, we come to the conclusion that the evidence amply supports the verdict reached by the jury. The testimony of Willa Watson places defendant on the premises during the crucial hours in direct contradiction to his alibi. This testimony also shows that defendant, after drinking for some time, entered her room and spoke briefly to her. He left with some of his clothes and the iron bar. She had also noticed the deceased occupying defendant’s bed a short time before. She heard defendant swear violently at the deceased and order him to leave the bed. She testified that defendant then reentered her room, threw the iron pipe down and left, but that he later came back and removed the pipe. This is corroborated by defendant’s own confession regarding his anger toward the deceased. The physical evidence shows blood spattered on defendant’s clothes in several areas. Some of this was shown by tests to be of the same type as that of deceased. Also of convincing probative importance is the confession made by defendant after he had made contrary statements to the police. In addition, there is defendant’s confes*1044sion to the former Assistant State’s Attorney. It is true that defendant denied these confessions but there is strong conflicting testimony by two witnesses.
In this appeal, as in most other similar situations, it is possible to raise various arguments concerning the weight of the testimony as counsel for defendant have done. Most of these arguments may readily be explained by counterarguments. For example, defendant points to the lack of fingerprints or blood of the same type as the deceased upon the angle iron. Someone apparently was responsible for cleaning this weapon which seemed from the evidence actually to be the murder weapon. Defendant first brought the angle iron back to Miss Watson’s room, then came out and removed it and it was found by the police in the room of Peter Reeves. The argument regarding defendant’s poor eyesight is advanced. It is true that this unfortunate condition would create sympathy for defendant’s plight but this does not rebut the evidence that defendant was actually the killer. It is also true that defendant called the police twice to report the presence of the dead body. This evidence in itself does not tend to exonerate defendant.
As regards the presence of the bloody dress soaking in the bathtub, this is at least partially explained by the statement made by Willa Watson concerning her head wound at or about that time. Similarly the stains on the floor in her room may logically be explained by the evidence that defendant threw the bar down on the floor. Also, failure of the record to explain each and every factual detail is not as important as is the weight of the totality of the evidence tending to prove defendant guilty.
It is only in the rarest case that the evidence of guilt is so overwhelming that no argument to the contrary and no conflict in the evidence appears. In our opinion, this record presents the usual case of conflicting evidence which went to the jury after a trial free from substantial error in which the jury was properly instructed. The jury in this case had the duty “to judge the credibility of witnesses, weigh the testimony and determine matters of fact. Tire determination of the jury will not be disturbed unless the evidence is so unsatisfactory as to justify a reasonable doubt of guilt.” (People v. Benedik, 56 Ill.2d 306, 310, 307 N.E.2d 382.) This principle has been described by the Supreme Court as axiomatic. People v. Glover, 49 Ill.2d 78, 84, 273 N.E.2d 367.
It is true that where the evidence “ # is not sufficient to remove all reasonable doubt of the guilt of the defendant and to create an abiding conviction that he is guilty, the conviction will be reversed.’ ” (People v. Hister, 60 Ill.2d 567, 573, 328 N.E.2d 531.) Our study of the record here convinces us that the verdict of guilty is amply supported by the evidence. In such a situation, we cannot “ * * lightly take *1045the step of reversing a jury’s determination of guilt’.” People v. Hister, 60 Ill.2d 567, 573.
Tire remaining point raised by defendant involves a classification of the evidence by the police and the former State’s Attorney regarding defendant’s own statements to them concerning his guilt. Defendant tendered an instruction relating to admissions. (IPI — Criminal No. 3.06.) The court refused this instruction and instead gave the jury one tendered by the State concerning a confession. (IPI — Criminal No. 3.07.) Both of these instructions, aside from respective use of the words “admission” and “confession,” told the jury that it was their duty to determine whether defendant made the admission, or confessed, and if so what weight should be given thereto with consideration of all of the circumstances under which the admission or confession was made.
There is a distinction in law between an admission and a confession. Actually an admission is not a complete acknowledgment of guilt as is a confession. A confession has been defined as “a comprehensive admission of guilt or of facts which necessarily and directly imply guilt.” (People v. Rollins, 119 Ill.App.2d 116, 131, 255 N.E.2d 471, leave to appeal denied, 43 Ill.2d 398.) In the case before us, both of these statements by defendant are indeed comprehensive admissions of guilt and of facts which necessarily and directly show guilt. Defendant told both of his interrogators that he had killed the deceased. He included a statement of the murder weapon and even went so far as to state the reasons for his attack upon the victim. In this situation, no complicated set of facts is required to constitute a “comprehensive admission of guilt.” We therefore conclude that the statements of defendant were correctly classified as confessions and that the jury was properly instructed. A recent case citing Rollins and reaching the same conclusion in response to the same argument is the opinion of this court in People v. Green, 30 Ill.App.3d 1000, 333 N.E.2d 478.
The judgment appealed from is accordingly affirmed.
