Borden, J.
The defendant, Raymond Cerilli, appeals1 from the judgments of conviction, after a jury trial, of the crimes of kidnapping in the first degree in violation of General Statutes § 53a-92 (a) (2) (A), sexual assault in the first degree in violation of General Statutes § 53a-70, attempt to commit sexual assault in the first degree in violation of General Statutes §§ 53a-70 and 53a-49 (a) (2), risk of injury to a child in violation of General Statutes § 53-21, and failure to appear in the first degree in violation of General Statutes § 53a-172.2 The defendant claims that: (1) the trial court [559]*559denied him due process of law by refusing to instruct the jury regarding the issue of identification; (2) the conduct of the New Haven police department resulted in the denial of his rights to confront witnesses, to the effective assistance of counsel and to due process of law by destroying or failing to produce crucial evidence; and (3) the trial court denied him due process of law by erroneously instructing the jury regarding the offense of failure to appear. We conclude that there was no reversible error, and we affirm the judgment.
The jury could reasonably have found the following facts. In October, 1987, the defendant lived in an apartment in Hamden, with his fiancee, Theresa Zumbo, and her daughter. On October 23, 1987, at approximately 9 p.m., the defendant and Zumbo, whose daughter was staying that evening with Zumbo’s mother, picked up a friend, Etta Goldberg, at her residence in the West-ville section of New Haven, and drove in the defendant’s car to “Sally’s,” a bar in New Haven. The [560]*560defendant’s car was a 1982 Malibu Classic, burgundy in color, with an automatic transmission, four doors and bench seats. There was a broken “piece” on the inside of the front passenger side door. The car was missing a glove compartment, and there were wires protruding from the glove compartment area.
The defendant, Zumbo and Goldberg stayed at the bar until approximately 2 a.m. Before they left, however, the defendant and Zumbo got into an argument that continued until they arrived at Goldberg’s residence. Zumbo and Goldberg entered Goldberg’s house and the defendant left. At approximately 2:30 a.m., Goldberg drove Zumbo to Zumbo’s mother’s house, where Zumbo spent the rest of the night. At some time before 3:15 a.m., the defendant returned to Goldberg’s house looking for Zumbo. Goldberg told him that she was at her mother’s house but refused to let him use the telephone to call Zumbo. At approximately 3:15 a.m., the defendant called Zumbo at her mother’s house from another telephone, but Zumbo refused to talk with him.
Meanwhile, N. W., the fourteen year old victim; and her friend, Raquel Reeves, were in the Westville section of New Haven, having visited friends. At approximately 3 a.m., they were walking toward downtown New Haven. As they reached Whalley Avenue, the defendant drove up to them and asked them if they wanted a ride. They accepted, and sat in the front seat of the defendant’s car. The victim sat next to the defendant and Reeves sat next to the door.
After starting to drive toward downtown, the defendant told the two girls that, because his car was not registered, he would have to drive on back roads so as not to be seen by the police. Thereafter, he stopped the car and told the girls to leave the car because he was going to take the highway. As Reeves left the car, the defend[561]*561ant put his arm around the victim’s neck, preventing her from leaving the car, and drove away onto a highway at a high rate of speed. When the victim began to scream, the defendant told her to stop or he would cut off her head. Reeves went to a nearby hospital and contacted the police.
During the drive, the victim was crying and asked the defendant why he was doing this to her. He told her that this would teach her not to be out so late, and that this would be a lesson to her. He also put his hand inside her shirt and touched her chest, and would not stop doing so when she told him to stop. She asked him to stop the car and let her out, but he refused.
After leaving the highway, the defendant, who was wearing a New York Giants sweatshirt, took another New York Giants sweatshirt from inside the car, wrapped it around the victim’s head and pushed her down in the seat. He continued to drive, and eventually parked the car on a hill. The defendant led the victim, the sweatshirt still wrapped around her head, out of the car, over a gravel surface, up some wooden steps, through two doors that the defendant opened with keys, and into a room where the defendant removed the sweatshirt from the victim’s head.
The victim was in a living room with wall-to-wall carpeting. The defendant brought her through a kitchen, which contained a double-door refrigerator, into a hallway that opened onto a bedroom on each side and a bathroom at the end. The defendant took her into one of the bedrooms. That room contained a waterbed with a wooden headboard, a dresser arranged kitty-cornered, two closets—one with sliding doors, containing women’s clothes—and a plaque on the wall that looked like it came from a bar. The lights were on.
The defendant ordered the victim to take off all of her clothes. She complied because she feared for her [562]*562life. The defendant removed his clothes, put a blanket on the bed and turned off the lights. He made the victim lie down on the bed. He tried to put his penis into the victim’s mouth but she refused. He then penetrated her vagina with his penis, but he could not maintain an erection. The defendant then began to insert his fingers into the victim’s vagina. He took some cream from the headboard, put the cream on his hands, inserted all his fingers into her vagina, and made a fist and pushed it into her vagina. When the victim began to scream, the defendant put a pillow over her head and told her to “shut up.” The victim heard a tearing sound in her vagina and felt herself begin to bleed.
When the defendant saw the blood, he told the victim to get dressed. The defendant then put the sweatshirt back over the victim’s head and led her back to the car. After driving for approximately ten minutes, he stopped the car, pushed the victim out and drove away. The victim removed the sweatshirt and left it on the street, where it was later retrieved by the New Haven police.
The victim walked to a gas station, where the police were called. The victim was taken by ambulance to the hospital, where she underwent surgery for a laceration of the vagina that extended the full length of the vaginal canal. This injury was consistent with a fist having been made inside the vagina.
At approximately 6:30 a.m., the defendant called Zumbo and they reconciled. After he picked her up at her mother’s house, they returned to their apartment. Zumbo noticed that the quilt was off the bed. The defendant said that he had spilled tea on it, that he had washed it and that it was in the dryer. The defendant had never washed the bedding or quilt before because that was ordinarily Zumbo’s responsibility. Zumbo checked the dryer and found the quilt in it.
[563]*563On November 2, 1987, after the victim had been released from the hospital, in the company of the police she identified the defendant’s car. She also positively identified the defendant from a twelve person photographic array as the person who had kidnapped and assaulted her. On the same day, Reeves also identified the defendant’s car and photograph.
The defendant was arrested later that day and brought to the New Haven police department where, after waiving his Miranda rights,3 he denied any involvement with the victim. He admitted owning the car identified by the victim and Reeves, however, and told the police that only he and Zumbo had access to it. He also told the police that he had been with Zumbo in their apartment from 7 p.m. on October 23, 1987, until the next morning.
Later that evening, the New Haven police searched the defendant’s apartment, and seized a jar of Vaseline petroleum jelly from the master bedroom and two New York Giants sweatshirts. They also took numerous photographs of the interior of the apartment and the exterior of the building.
I
The defendant first claims that the trial court denied him due process of law by refusing to instruct the jury specifically on the issue of identification. It is undisputed that the court did not give a specific instruction on identification.4 Relying on our language in State v. Tatum, 219 Conn. 721, 733 n.18, 595 A.2d 322 [564]*564(1991),5 the defendant argues that, although neither the victim nor Reeves was uncertain of her identification of the defendant, their testimony regarding that identification and the defendant’s car was so confused and inconsistent6 that, “given the defense reliance on the [565]*565theory of misidentification, it was reversible error for the trial court to refuse to instruct the jury specifically that the State bore the burden of proving identification beyond a reasonable doubt.” The defendant further contends that “it was incumbent upon the trial court to give the cautionary identification instruction requested by the defense,”7 and since that instruction [566]*566was not given, the “defendant was denied due process of law by the failure of the court to instruct on identification . . . .” We disagree.
[567]*567Neither State v. Tatum, supra, nor any of the other cases upon which the defendant relies; see United States v. Telfaire, 469 F.2d 552 (D.C. Cir. 1972); State v. Pollitt, 205 Conn. 132, 531 A.2d 125 (1987); State v. Davis, 198 Conn. 680, 504 A.2d 1372 (1986); State v. McKnight, 191 Conn. 564, 469 A.2d 397 (1983); supports the defendant’s argument that an identification instruction is constitutionally required. Indeed, we have recently held that “[e]ven if [a] court’s instructions were less informative on the risks of misidentification than they might have been, the issue is at most one of instructional error rather than of constitutional error. A new trial would only be warranted, therefore, if the defendant could establish that it was reasonably probable that the jury was misled.” State v. Tillman, 220 Conn. 487, 501, 600 A.2d 738 (1991); see also State v. Anderson, 20 Conn. App. 271, 281, 566 A.2d 436 (1989), cert. denied, 213 Conn. 813, 569 A.2d 549 (1990) (no constitutional right to instruction on fallibility of eyewitness identification).
We agree with the defendant that a specific instruction on identification was warranted because his theory of defense was misidentification and because there were sufficient instances of lack of clarity and sufficient inconsistencies in the identification testimony of the victim and Reeves. See footnote 6, supra. We conclude, however, that any such instructional lacuna did not constitute reversible error. This is not a case where the conviction turned on the “uncertain, unclear or inconsistent” eyewitness identification of the defendant by the victim and Reeves. (Internal quotation marks omitted.) State v. Tatum, supra, 733 n.18. There were sufficient certainties and consistencies in the testimony of the victim and Reeves, sufficient evidence corroborating that testimony and strong evidence of consciousness of guilt so that there was no reasonable probability that the jury was misled.
[568]*568First, shortly after the crimes, both the victim and Reeves selected the defendant’s photograph from among an array of twelve photographs. Both these identifications were positive, and the defendant has not challenged the fairness of that procedure. Moreover, they both positively identified the defendant at trial.
Second, despite the inconsistencies in the victim’s and Reeves’ descriptions of the assailant, there were also elements of consistency with the defendant’s appearance. They both described the defendant as a stocky white male, in his thirties, with curly, shoulder length hair. In one of her pretrial statements to the police, the victim also described the color of the defendant’s hair as “real dark brown, almost like a black,” his eyebrows as thick and separated rather than running together, and his hands as “like rough for construction workers.”8
Third, both the victim and Reeves positively identified the defendant’s car. Reeves accurately described the broken piece on the interior of the front passenger side door, and they both accurately described the missing glove compartment and exposed wires.
Fourth, the victim accurately described both the exterior and the interior of the defendant’s apartment. She described the apartment as being on a hill, with a gravel approach and several wooden steps leading to the front entrance, which consisted of two separate doors that had to be opened. She described the layout of the interior: a living room with wall-to-wall carpeting, leading to a kitchen with a double-door refrigerator; then a hallway off of which were two bedrooms and at the end of which was the bathroom. She*also described the bedroom in which the assault took place as containing a waterbed, two closets—one of which contained [569]*569women’s clothes—a dresser kitty-cornered, and a plaque on the wall that looked like it came from a bar. All of these descriptions were consistent with the photographs9 taken by the police and with Zumbo’s testimony.
The victim’s testimony was also corroborated by a jar of Vaseline petroleum jelly and two New York Giants sweatshirts that the police seized from the defendant’s apartment. The victim’s testimony that she had bled on what she described as the blanket the defendant had put on the bed was corroborated by Zumbo’s testimony that, although the defendant had never washed the bedding before, when she arrived home on the morning of the assault she found that he had washed and dried the bed quilt.
Fifth, there was evidence that the defendant was in the Westville section of New Haven, in his car, around the time of the abduction of the victim. He left Goldberg’s residence at some time between 3 a.m. and 3:15 a.m., and the abduction took place some time shortly after 3 a.m.
Sixth, there was strong evidence of consciousness of guilt on the defendant’s part. The alibi he offered to the police when he was arrested, specifically, that he had been home with Zumbo the entire evening prior to and the morning of the crime, was contradicted by Zumbo’s testimony regarding her own whereabouts and those of the defendant and of Goldberg during the time period in question. Further, there was evidence of his flight from the state, his fear of returning to face the charges, his initial refusal to waive extradition, and his escape from jail in New York.
[570]*570Furthermore, it is not reasonably probable that the jury was misled by the court’s failure to instruct the jury precisely as the defendant requested because the court complied in part with the defendant’s request to charge on the issue of identification. State v. Tillman, supra. That request; see footnote 7, supra; contained essentially four elements: (1) a focus on the importance of identification as one of the most important issues in the case, and the requirement that the jury be satisfied beyond a reasonable doubt that the defendant was the perpetrator; (2) the capacity and opportunity of the witnesses to observe the perpetrator; (3) whether the identification of the defendant, subsequent to the offense, was the product of the witnesses’ own recollection; and (4) an assessment of the credibility of the witnesses under general standards governing credibility.
Although the charge did not specifically refer to the first factor, the court did advert to that factor by instructing the jury that it must be satisfied beyond a reasonable doubt that the defendant had committed the crimes charged.10 With regard to the second factor, the court specifically instructed the jury that, in weighing the credibility of the witnesses, it should consider their “ability to observe objectively, and to remember and [571]*571relate [their] observations here accurately.” The court gave no instruction specifically aimed at the third factor, but that omission was perfectly appropriate because the defendant had made no claim that the pretrial identifications of the defendant by the victim and Reeves were tainted. In fact, after filing a challenge to those identifications, the defendant withdrew the challenge because the evidence indicated no suggestiveness in the identification process. Finally, with regard to the credibility of the witnesses, the trial court gave a thorough and accurate instruction on the principles of credibility of witnesses. The court, therefore, complied substantially with two of the four factors suggested in the defendant’s request to charge. It adverted as well to one of the remaining factors, and the third remaining factor was not pertinent to the evidence in the case.
In sum, although there were certain inconsistencies and instances of lack of clarity in the victim’s and Reeves’ identifications of the defendant, there were also significant and reliable certainties in those identifications, significant and reliable corroborating evidence, and significant evidence of the defendant’s consciousness of guilt. Furthermore, the court complied in part with the defendant’s request to charge on those identifications. Under all these circumstances, it is not reasonably probable that the jury was misled regarding the issue of the identification of the defendant as the perpetrator of the crimes charged.
In place of this analysis, the dissent offers a general exegesis on the dangers of cross-racial eyewitness identification. It is difficult to discern, however, precisely what governing principle the dissent does employ to reach its conclusion of reversible error in this case. Apparently the dissent’s argument, offered without supporting authority, is that whenever there is a cross-racial identification and the trial court does not give [572]*572a Telfaire-type instruction, a new trial is required regardless of the facts of the case. United States v. Telfaire, 469 F.2d 552 (D.C. Cir. 1972). Nowhere, of course, does the dissent refute—or, indeed, even discuss—the six fact-based factors in this case that, even apart from the trial court’s partial compliance with the defendant’s request to charge, undercut any reasonable probability that the jury was misled by the trial court’s failure to give a specific identification instruction.
II
The defendant next claims that he was denied his rights to confront and cross-examine witnesses, to the effective assistance of his counsel, and to due process of law because the New Haven police destroyed or failed to produce crucial evidence.11 The evidence that he claims was destroyed or not produced in violation of his rights consists of the original tape recording of a police interview with the victim,12 the 911 and all dispatch tapes, certain Polaroid photographs the police took of the defendant upon his arrest, and sketches of his nose purportedly made by Reeves. The defendant’s claims do not withstand analysis in the light of the facts in the record.
On November 23,1987, the defendant filed a motion to preserve evidence requesting in pertinent part a court order to the state and the New Haven police department “to take all reasonable step[s] to preserve all documents, including all tapes, transcriptions or [573]*573other recordings of all telephone calls to the police from the complaining witness or any other witness reporting this incident (including 911 calls originally reporting the incident), all dispatcher tapes . . . and any and all other . . . tapes and photographs pertaining to this case . . . .” The court, Ronan, J., granted, in part, this motion on December 7, 1987.13
Shortly before the trial, in November, 1990, the defendant filed a motion in limine to prohibit the testimony of the victim and of certain police officers, based upon claims that the police had improperly erased a tape of an interview with the victim and the twenty-four hour reel-to-reel tape recording of all communications with the New Haven police department on October 24, 1987. The pretrial hearing on this motion yielded the following evidence.
In the early morning hours of October 24,1987, after the abduction of the victim, Reeves went to Yale-New Haven Hospital and reported the incident to a police officer there. After the victim had been released by the defendant, the victim went to a gas station on State Street, where the attendant called the police. The victim testified that she had gotten on the telephone and said, “I just got raped.” She further testified that the police had asked her if she were N.W., and when she had responded, “Yeah,” the police had said, “We’ve got Raquel down here now. Where you at?” The station attendant then took the phone and gave the police their location. The victim was then transported by ambulance to the hospital, where she gave a limited description of her abductor.
[574]*574The following day, Detective Ralph Dinello, of the New Haven police department, interviewed the victim at the hospital. This interview was not tape recorded, but was reflected in Dinello’s subsequent report. On October 26,1987, Dinello interviewed the victim a second time at the hospital. This interview was tape recorded on a cassette recorder.
The cassette tape of the victim’s October 26, 1987 interview was later given to Barbara Coughlin for transcription. Coughlin was an administrative assistant in the New Haven police department investigative services unit. In accordance with the procedures in place in 1987, after transcribing the tape Coughlin placed it in Dinello’s mail slot. Although Dinello believed he then returned the tape to the evidence room, a search of that room failed to disclose it. In fact, at that time, such tapes were often erased and reused.14 Thus, although the tape was not available to the defendant, the forty-two page transcript of the interview with the victim was available.
That transcript discloses certain gaps because some parts of the tape were inaudible. Coughlin’s practice in transcribing a tape was as follows. If she reached an inaudible part, she would listen to it several times in an attempt to discern what was on it. If she was still unable to hear the words, she would ask someone else in the office to listen to it. If that procedure proved unavailing, she would leave a blank space in the transcript.
The pretrial hearing also disclosed that on November 2,1987, the victim and Reeves positively identified [575]*575the defendant from a photographic array, and also gave statements that were stenographically recorded. These statements, which were not tape recorded, were available to the defendant. Furthermore, on November 4, 1987, the victim gave another tape recorded statement to the police. Both the twenty-nine page transcript and the tape of this statement were available to the defendant.
Regarding the reel-to-reel tape, Lieutenant Stephen Jankowski testified in the pretrial hearing that he had not received notification that the tape was to be preserved. He further testified that the tape had been erased and reused in its regular rotation, in accordance with the police department’s practice in 1987. Thus, this tape was not available to the defendant.
The trial court, McKeever, J., denied the defendant’s motion in limine. The court found that, although the tape of the victim’s October 26,1987 interview and the reel-to-reel tape had been intentionally destroyed, they were not destroyed in bad faith. The court also concluded that the unavailability of these tapes did not prejudice the defendant sufficiently to warrant preclusion of the testimony of any witness.
During the trial, two additional matters arose. On the basis of a police report dated November 9, 1987, the defendant discovered that when he had been initially arrested, the police had taken Polaroid photographs of the defendant showing his hands, face and full body, and that the photographs were missing. The defendant moved to dismiss the information, claiming that the missing photographs were “critical for the defendant’s use in regard to the identification testimony by all parties in this case.” The court denied the motion. The court concluded that the defendant had not been prejudiced because his police “mug shot,” taken on the same day, served the same essential pur[576]*576pose as the missing photographs. The court also noted that the defendant could have taken his own photographs at the time.
Also, during the trial Reeves testified that, while she was at the hospital immediately after the abduction, she had “tried to draw [the defendant’s] nose, you know, the shape of his nose” on several pieces of paper, but she did not know whether the police had taken the drawings or what had happened to them. Dinello testified that he had not received any sketches from Reeves and could not recall receiving any sketches from other police officers. At no time during the trial did the defendant make a claim or file a motion regarding these purported sketches.
In its instructions to the jury, the court charged, in accordance with the defendant’s request, that although the state is not required to produce all the available evidence in the case, if the jury found that there was evidence available only to the state that the state “would naturally have produced,” the jury could, but was not required to, draw an inference that the evidence was unfavorable to the state. The court specifically related this instruction “to the audio tapes and photographs” that had not been made available to the defendant.
A
Against this factual background, we turn first to the defendant’s claim regarding the tape of the victim’s October 26,1987 statement. The defendant argues that the erasure of that tape “denied the defendant an opportunity to fully cross-examine the victim and the only eyewitness on the inconsistencies in the crucial description of the defendant, the automobile, the apartment, the route [they traveled], and the whereabouts of the house where [the victim] was assaulted,” and that the state “has not carried its burden of establishing that [577]*577the non-production of this crucial evidence was harmless beyond a reasonable doubt.” We disagree.
There is no question that the tape was a “statement” of the victim and, therefore, disclosable to the defendant pursuant to Practice Book §§ 749, 750 and 752. “We have recently set forth the analysis to be applied in such cases. [I]f a case involves intentional, but not bad faith, destruction of the statement of a state’s witness, an automatic sanction of striking that witness’ testimony is not required. [State v. Williamson, 212 Conn. 6, 15-16, 562 A.2d 470 (1989)]. State v. Johnson, 214 Conn. 161, 168, 571 A.2d 79 (1990). Rather, under such circumstances, it is appropriate that the court weigh the culpability of the state for its failure to make disclosable material available on the one hand, against any resulting prejudice to the defendant on the other. State v. Myers, [193 Conn. 457, 469, 479 A.2d 199 (1984)]; State v. Shaw, [185 Conn. 372, 386, 441 A.2d 561 (1981), cert. denied, 454 U.S. 1155, 102 S. Ct. 1027, 71 L. Ed. 2d 312 (1982)]. State v. Santangelo, [205 Conn. 578, 587-88, 534 A.2d 1175 (1987)]; State v. Mullings, [202 Conn. 1, 10, 519 A.2d 58 (1987)]. State v. Williamson, supra, 14. This approach gives broad discretion to the trial court. Id. Where . . . the destruction of a witness’ statement, although not in bad faith, is deliberate, the state properly bears the burden of establishing harmlessness. Id., 18. . . .” (Internal quotation marks omitted.) State v. Belle, 215 Conn. 257, 267-68, 576 A.2d 139 (1990). In this context, “bad faith” means “ ‘a deliberate act done with intent to deprive the defense of information.’ ” Id., 265 n.8.
Furthermore, absent a showing that the defendant’s constitutional right of confrontation was violated by the erasure of the tape, the state need only prove that it was more probable than not that the nonproduction was harmless. Id., 271. Where, however, the state’s failure to produce material to which the defendant was [578]*578entitled so adversely affects the defendant’s ability to cross-examine the witness that it “infringe[s] upon his constitutional right of confrontation,” the state must prove harmlessness beyond a reasonable doubt. Id., 269.15
The defendant does not challenge the trial court’s finding that the erasure of the tape was not done in bad faith. We therefore must determine whether the trial court abused its broad discretion in weighing the state’s culpability against the prejudice to the defendant. We conclude that the court did not abuse that discretion in refusing to preclude either the victim or any of the police officers from testifying. We also conclude, contrary to the defendant’s claim, that (1) the failure of the state to produce the tape did not deprive him of his right of confrontation, and (2) it is more probable than not that the erasure of the tape was harmless.
The culpability of the state, while not minimal, was not egregious. Contrary to the suggestion of the defendant that the tape was erased “in contempt of [579]*579a direct order of the Superior Court,” there is nothing in this record to indicate that the tape was erased after December 7, 1987, when the trial court granted the defendant’s motion to preserve evidence, or that the police received notice of the order.
Nor is it wholly accurate to state, as the defendant does, that the erasure was “a dramatic illustration of the continued behavior of the New Haven Police Department to destroy evidence ... in direct contravention of the rulings of the appellate courts of the State.” It is true that certain of our cases in which the New Haven police department had lost or erased tape recordings of witnesses’ statements predated the conduct of the police in this case. See, e.g., State v. Mullings, 202 Conn. 1, 5-11, 519 A.2d 58 (1987) (erasure of tape recording of witness’ statement harmless error); State v. Myers, supra, 466-69 (erasure of tape of victim’s anonymous telephone call to police harmless error); State v. Shaw, supra, 384-87 (loss of tape not reversible error because unavailability of tape unintentional and prejudice slight). It is also true, however, that we recognized in State v. Mullings, supra, 9, that “our holding in Myers could reasonably have been interpreted ; excusing the erasure of tapes so long as a verbatim transcript was preserved,” and that the decisions in other cases involving the New Haven police department postdated the conduct of the police in this case. See, e.g., State v. Belle, supra; State v. Johnson, supra; State v. Kelly, 208 Conn. 365, 545 A.2d 1048 (1988); State v. Santangelo, supra, 589-91.
The prejudice to the defendant, moreover, was slight. First, despite the argument of the defendant to the contrary, we can perceive no prejudice resulting from the gaps in the transcript. Considering the pains that Coughlin had taken in attempting unsuccessfully to discern what the victim had said in the inaudible portions of the tape, there is no reason to think that, had the [580]*580tape itself been available, the defendant would have been any more successful in discerning that inaudible material. Furthermore, the defendant had available for use in his cross-examination of the victim the forty-two page transcript of that interview, the tape recording and twenty-nine page transcript of her subsequent interview, and the transcript of her pretrial testimony. Thus, “impeachment materials available to the defendant were in ample supply.” State v. Joly, 219 Conn. 234, 247, 593 A.2d 96 (1991). Finally, the court instructed the jury that it could draw an inference adverse to the state from the failure to produce the tape. Under these circumstances, we conclude that the failure to preserve the tape in question did not violate the defendant’s right of confrontation, and that it was more probable than not that the erasure of the tape was harmless.
B
We also agree with the state that the erasure of the reel-to-reel tape containing the victim’s statement to the police during the telephone call from the gas station was harmless. The only significant statement the victim made in that telephone call was that she had just been raped. That was wholly consistent with all of her pretrial statements and testimony, and with her testimony at the trial. The defendant’s suggestion that the loss of this tape hindered his ability to pin down the time of the assault is not supported by the record. There was in evidence a copy of the police complaint card indicating that at 3:56 a.m. Reeves notified the police from Yale-New Haven Hospital that the victim had been abducted. Therefore, the police were already aware of the complaint when the telephone call from the gas station took place. Thus, the trial court did not abuse its discretion in declining to bar the victim’s testimony because of the erasure of the reel-to-reel tape.
[581]*581c
With regard to the loss of the Polaroid photographs of the defendant, we also agree with the state that the trial court did not abuse its discretion in declining to bar the testimony of any of the policemen. Although the photographs would have been relevant and might have been helpful to the defendant, there is no evidence that they were lost through bad faith on the part of the police. As the trial court noted, the mug shot of the defendant taken on the same day served as something of a substitute for these photographs, and there was nothing to preclude the defendant from having his own photographs of himself taken in order to preserve photographs of his distinctive tattoos for demonstrative evidence later. Furthermore, the defendant was able to cross-examine both the victim and Reeves extensively, and the trial court’s instruction, permitting the jury to draw an inference adverse to the state, specifically referred to the photographs. Under these circumstances, the loss of these photographs did not deprive the defendant of his right of confrontation regarding any witness.
D
Finally, the defendant’s unpreserved claim regarding the purported loss of Reeves’ sketches of the assailant’s nose founders on the first prong of State v. Golding, 213 Conn. 233, 239, 567 A.2d 823 (1989), namely, that there must be an adequate record to review such a claim. Although Reeves testified that she had tried to draw the defendant’s nose, she did not know whether the police had taken her drawings. Dinello testified, however, that he had not received any such sketches and that he could not recall ever receiving such sketches from other police officers. Since the defendant raised no claim at trial regarding this issue, [582]*582the trial court had no opportunity to determine whether any such sketches had in fact been made or delivered to the police. Accordingly,, the defendant cannot prevail on this claim. Id.

The defendant’s final claim is that, with regard to his conviction for failure to appear, the trial court deprived him of due process of law by instructing the jury that the state need not prove an intentional failure to appear. We agree with the defendant that the trial court’s instruction was improper, but we also agree with the state that, under the facts of this case, the error was harmless beyond a reasonable doubt.
On February 3, 1988, the defendant had been released on a combined real estate and professional surety bond for the kidnapping and sexual assault charges filed against him. The defendant’s grandmother owned the real estate partially securing the bond. Thereafter, he received personal notice, served by a sheriff, Of a bond modification hearing scheduled for April 21,1988. The professional bondsman also specifically told the defendant of the April 21 court date. This was the first scheduled court appearance after his release. On the morning of April 21, the defendant told Zumbo that he would be in court, but he did not appear. Zumbo, the defendant’s grandmother and the bondsman appeared in court. The court ordered the bond forfeited and the defendant rearrested.
Thereafter, the defendant telephoned Zumbo several times but refused to tell her where he was. In June, 1988, he picked up Zumbo and her daughter in New Haven and they left the state. When Zumbo told the defendant to turn himself in, he responded that he was afraid of going to jail.
[583]*583In July, 1988, the defendant was arrested in a motel room in Easton, New York, where he had been staying with Zumbo, and charged with being a fugitive from justice. He told the arresting officers that he would not waive extradition because he did not want to face the pending charges. Two weeks later, he escaped from the county correctional facility in New York, and was captured approximately thirty-six hours later. On May 3, 1989, he was returned to the custody of Connecticut law enforcement officials to stand trial on these charges.
The court instructed the jury that the state was obligated to prove beyond a reasonable doubt the following essential elements of the crime: (1) the defendant had been released on bail upon the condition that he appear personally in court at a future given date; (2) the defendant was required to appear in court on April 21, 1988, in connection with the charges of kidnapping, unlawful restraint and risk of injury to a child; and (3) the defendant wilfully failed to appear as required. In this connection, the court also charged that “an act is done willfully if done knowingly, intentionally, and deliberately.”
The court then stated as follows: “You are instructed, however, that the State need not prove an intentional failure to appear. The mere showing by the State that the defendant failed to appear on his scheduled date is sufficient to establish a prima facie case.” It is this language, to which the defendant took proper exception, that the defendant claims, and the state does not seriously dispute, improperly “relieved the State of the burden of proving intent or state of mind beyond a reasonable doubt.”
We agree with the Appellate Court that “[i]n order to prove the ‘wilful’ element of General Statutes § 53a-172, the state must prove beyond a reasonable [584]*584doubt either that the defendant received and deliberately ignored a notice to appear or that he intentionally embarked on a course of conduct designed to prevent him from receiving such notice.” State v. Candito, 4 Conn. App. 154, 157, 493 A.2d 250 (1985). The challenged language in the court’s charge improperly either eliminated wilfulness as an issue or shifted the burden of proof on that issue to the defendant. It therefore ran afoul of the principles of Sandstrom v. Montana, 442 U.S. 510, 99 S. Ct. 2450, 61 L. Ed. 2d 39 (1979), and Francis v. Franklin, 471 U.S. 307, 105 S. Ct. 1965, 85 L. Ed. 2d 344 (1985).
As the defendant concedes, however, that determination does not end the inquiry because such an error is harmless if “ ‘the reviewing court may confidently say, on the whole record, that the constitutional error was harmless beyond a reasonable doubt.’ ” Rose v. Clark, 478 U.S. 570, 576, 106 S. Ct. 3101, 92 L. Ed. 2d 460 (1986), quoting Delaware v. Van Arsdall, 475 U.S. 673, 681, 106 S. Ct. 1431, 89 L. Ed. 2d 674 (1986).16 This record establishes such harmlessness.
The evidence of the defendant’s wilfulness in failing to appear was undisputed and overwhelming. After his release on bond, his professional bondsman twice gave him personal notice of the April 21, 1988 court date. On the morning of April 21 he acknowledged to Zumbo his obligation to appear. Thereafter, he called Zumbo several times but refused to tell her where he was. In June, 1988, he left the state with Zumbo and her daughter, and when she urged him to turn himself in to the [585]*585Connecticut authorities, he said that he was afraid of going to jail. After his arrest in New York, he refused to waive extradition because he did not want to face the charges pending against him here, and approximately two weeks later he escaped from jail in New York. Under these circumstances, there is no reasonable possibility that the jury was misled into convicting him without also finding that his failure to appear was wilful.
The judgment is affirmed.
