OPINION
NIERENGARTEN, Judge.Appellant Carl White appeals his conviction of first degree criminal sexual conduct. We affirm.
FACTS
On the evening of January 29,1984, K.H. left her home intending to walk to a friend’s house. She accepted a ride from a man driving a maroon-colored car. She talked and smoked Benson & Hedges cigarettes with the driver, “Kevin”, and agreed to ride around with him. They left the downtown Minneapolis area, eventually passing a Sperry Univac facility where they parked behind a building with some white tanks. Kevin told K.H. to remove her clothes. K.H. objected and started to walk away from the car but was struck on the back of her head by a fist and knocked to the ground. She saw Kevin holding a tire wrench in his hand. Kevin ordered K.H. back into the car and told her to remove her clothes. When K.H. established she was menstruating by removing her tampon and discarding it outside the car, Kevin said he would take her home.
Instead, Kevin parked behind an old building in the downtown area and told K.H. to perform oral sex on him. Although K.H. complied for a few moments, Kevin ordered K.H. into the back seat, told her to remove her clothes, and then had sexual intercourse with her. Kevin later drove K.H. back to the street where he picked her up. K.H. noted the license plate number as Kevin drove away.
When K.H. returned to her apartment she did not wake her boyfriend but called the police to whom she explained the details of the assault, described Kevin’s clothes and physical characteristics, his car, and its license plate number. K.H. also described several items in Kevin’s car including a speedometer with large lettering, an orange disc with the word “stop” hanging from the rear view mirror, a maroon pillow, soft seats, and an empty glove compartment.
A hospital sexual assault examination did not indicate any injuries or bruises and there was no evidence of semen. K.H.’s clothing was not torn or scuffed.
The car was registered to Carl White’s sister-in-law. White’s brother told the police he had lent the car to White who later was arrested at his parents’ restaurant when he arrived driving the car.
The car was impounded and searched, and several items were seized from the car including an orange disc with the word “stop” hanging from the rear view mirror, a maroon pillow, and several Benson & Hedges cigarette butts from the ashtray. The police did not find a tire wrench in the car. A lab analysis of a stain on the back seat showed that the stain did not contain either blood or seminal fluid. None of K.H.’s fingerprints were found in the car. Analysis of the nine cigarette butts indicated that seven cigarettes were smoked by a blood type 0 “nonsecretor.” White is a blood type 0 nonsecretor. One of the cigarettes was smoked by a blood type 0 secretor. K.H. is a blood type O secretor.
White voluntarily told the police he had been driving the car for the past month, but that he had not loaned the car to anyone other than his girlfriend. He denied knowing K.H. White said that he went to his parents’ restaurant at about 6:00 p.m. on January 29 to prepare meat, left the restaurant at about 8:30 p.m. and drove to a bar where he stayed until 11:15 or 11:30, and then returned to the restaurant where he stayed for about forty-five minutes, arriving home about 12:30 a.m.
On February 3, K.H. identified White from a lineup consisting of White and five other black males. Although K.H. initially told the police her assailant did not have *199any facial hair, her formal statement to the police indicated that her assailant had a beard. White had a small beard. The police attempted to locate the building with the white tanks where K.H. said she discarded her tampon. Although they could not find that site, they did locate the place where the actual assault occurred.
White was charged with two counts of criminal sexual conduct. He pled not guilty and asserted an alibi defense claiming he was preparing meat at his parents’ restaurant on the night of the assault. His parents testified that they talked to White in the restaurant between 7:30 and 7:45 p.m. on their way to church but did not see White at the restuarant when they returned home at about 10:00 p.m. The next day the meat, which required five hours preparation, was prepared as usual and was in the refrigerator. White’s girlfriend testified White arrived home at about 12:30 a.m.
White was convicted of first degree criminal sexual conduct.
ISSUES
1. Was the appellant denied due process of law when the trial court excluded evidence of the victim’s venereal disease and failed to strike the victim’s identification testimony?
2. Did the prosecutor’s statements during closing argument deny the appellant his right to a fair trial?
3. Was the evidence sufficient to support the appellant’s conviction of first degree criminal sexual conduct?
4. Did the sentencing court err by denying the appellant’s motion for a downward departure from the presumptive sentence under the sentencing guidelines?
ANALYSIS
1. Due Proces Claims
White claims he was denied due process of law because the trial court excluded evidence that K.H. had a venereal disease at the time of the assault. He also argues that the trial court should have striken K.H.’s identification testimony.
Excluded Testimony
A criminal defendant must be provided a meaningful opportunity to present a complete defense. California v. Trombetta, 467 U.S. 479, 485, 104 S.Ct. 2528, 2532, 81 L.Ed.2d 413 (1984). Persons accused of crimes may be denied due process rights if material exculpatory evidence is not presented to the jury. Brady v. Maryland, 373 U.S. 83, 87, 83 S.Ct. 1194, 1196, 10 L.Ed.2d 215 (1963).
K.H. had gonorrhea of the anal area at the time of the assault. White’s test results for veneral disease were negative. White argued that the evidence of K.H.’s gonorrhea and his lack of veneral disease was admissible as probative evidence of the assailant’s identity and White’s lack of involvement. White asserted he was linked to the assault only by K.H.’s identification of White and the car. The State argued the evidence was irrelevant because there was no allegation of anal intercourse and that the evidence was prejudicial to K.H.
The record suggests the trial court decided the evidence was inadmissible because of foundation problems since mislabeled lab samples made it unclear whether K.H.’s venereal disease was located in the anal or vaginal area.
Under very limited circumstances, evidence of a victim’s venereal disease might be admissible to prove identity. See Minn.R.Evid. 404(c)(1); State v. Mason, 152 Minn. 306, 310, 189 N.W. 452, 453 (1922) (the trial court could admit evidence of the victim’s venereal disease to prove she was assaulted by the defendant who had venereal disease). However, evidence is not admissible unless it also is relevant. See Minn.R.Evid. 402. Even then, relevant evidence may be excluded “if its probative value is substantially outweighed by the danger of unfair prejudice, confusion of the issues, or misleading the jury * * *." Minn.R.Evid. 403 (emphasis added). See Minn.R.Evid. 404(c)(2)(C) (evidence of a victim’s previous sexual conduct may be admissible if “its probative value is not sub*200stantially outweighed by its inflammatory or prejudicial nature”).
We cannot conclude that the court erred by excluding evidence of K.H.’s venereal disease. The relevancy of the evidence is questionable and, in light of the apparent mislabeling of test samples and the impossibility of retesting K.H. for venereal disease, we do not believe defense counsel could establish proper foundation for the evidence.
Identification Testimony
Sometime between the initial mistrial of this case and the trial in August 1986, the State lost the photograph of the lineup from which K.H. first identified White as the assailant. The record does not indicate that the lineup was prejudicial or suggestive. At the Rasmussen hearing, the court had the lineup photograph before it, concluded there was nothing suggestive about the lineup procedures, and denied White’s motion to suppress the identification testimony. The evidence did not possess “an exculpatory value that was apparent before the evidence was destroyed.” Trombetta, 467 U.S. at 489, 104 S.Ct. at 2534. The trial court did not err by failing to strike K.H.’s testimony describing her out-of-court identification of White.
In addition the trial court did not err by refusing to strike K.H.’s in-court identification because, under the circumstances, we cannot conclude there was a “substantial likelihood of misidentification.” See Neil v. Biggers, 409 U.S. 188, 201, 93 S.Ct. 375, 383, 34 L.Ed.2d 401 (1972). K.H. had ample opportunity to view White during the approximately two hours she spent with him, including time when she was not alarmed or suspicious. Although K.H. originally said White did not have a beard, she readily identified him when she viewed him at the lineup three days after the assault. See State v. Reichenberger, 289 Minn. 75, 79, 182 N.W.2d 692, 695 (1970) (“the task of weighing [witness] credibility was for the jury,” not the appellate court); State v. Beard, 380 N.W.2d 537, 541 (Minn.Ct.App.1986), pet. for rev. denied, (Minn. Mar. 3, 1986) (“minor inconsistencies between [the victim’s] testimony and her previous statements are not grounds for reversing the jury’s guilty verdict”).
2. Closing Argument
White also argues that the prosecutor improperly suggested to the jury that the State need not prove certain elements of the crime.
[T]he Due Process Clause protects the accused against conviction except upon proof beyond a reasonable doubt of every fact necessary to constitute the crime with which he is charged.
In re Winship, 397 U.S. 358, 364, 90 S.Ct. 1068, 1073, 25 L.Ed.2d 368 (1970).
“[T]he state cannot shift to one accused of a crime the burden of proving his innocence.” State v. Townsend, 259 Minn. 522, 529, 108 N.W.2d 608, 613 (1961). Although White argues it was improper and objectionable for the prosecutor to suggest during closing argument that certain elements of the crime might be deemed established because White denied any involvement in the assault, the argument did not deprive White of a fair trial. The prosecutor’s references to White’s prior statements to the police were not improper, and both the prosecutor and defense counsel told the jury on several occasions that the State has the burden of proving White’s guilt beyond a reasonable doubt, that the State was required to prove White was the assailant, and that each of the elements of the crime had to be proven beyond a reasonable doubt. In addition, it appears that the statements were neither obvious nor important to defense counsel because he failed to object when the statements were made. See State v. Spencer, 311 Minn. 222, 230, 248 N.W.2d 915, 920 (1976). Further, at defense counsel’s request, the trial court instructed the jury that White was not required to testify and that the jury should not draw any adverse inferences from the fact that White did not testify.
“The propriety of a prosecutor’s final argument is a matter within the sound discretion of the trial court.” State v. Parker, 353 N.W.2d 122, 127 (Minn.1984) (citation omitted). The trial judge is in the best position to determine whether an improper *201statement has had an adverse effect on the jury. See State v. Johnson, 277 Minn. 230, 235, 152 N.W.2d 768, 772 (1967), cert. denied sub nom., Johnson v. Minnesota, 390 U.S. 990, 88 S.Ct. 1190, 20 L.Ed.2d 1297 (1968). The trial court’s instructions adequately mitigated any adverse affect the prosecutor’s statements might have had on the jury.
3. Sufficiency of the Evidence
White asserts that the evidence does not support his conviction of first degree criminal sexual conduct. A conviction may be upheld and the verdict of a trial court
will not be disturbed where, upon review of the record, it appears that the evidence, direct and circumstantial, viewed most favorably to support a finding of guilty, was sufficient for the jurors to reach that conclusion.
State v. Otten, 292 Minn. 493, 494, 195 N.W.2d 590, 591 (1972) (citations omitted).
There is sufficient evidence from which the jury could conclude beyond a reasonable doubt that White was the assailant and guilty of first degree criminal sexual assault. K.H. was emotionally upset and crying after the assault; she reported the assault immediately; she described the assailant’s car as well as several items in the vehicle; lab analyses indicated she could have smoked cigarettes found in the ashtray and the site where K.H. was assaulted was located. Finally K.H. positively identified White as the assailant when she viewed him at the police lineup three days after the assault. “On review, this court will assume that the jury believed the State’s witnesses and disbelieved any contradictory testimony.” Beard, 380 N.W.2d at 541.
Jf. Presumptive Sentence
White contends the sentencing court erred by denying his motion for a downward departure from the presumptive sentence under the sentencing guidelines because the court allegedly was unfamiliar with the specific facts of his case. The sentencing judge indicated that he imposed the guideline sentence primarily because he did not preside at White’s trial and did not have an opportunity to hear the evidence or the facts presented at the trial.
The record indicates that the sentencing judge adequately apprised himself of White’s circumstances and the facts of the case and reviewed the presentence investigation and psychological report. The judge did not abuse his discretion by declining to depart from the presumptive sentence.
DECISION
The appellant was not denied due process of law when the trial court excluded evidence of the victim’s venereal disease and refused to strike the victim’s identification testimony. The prosecutor’s closing arguments did not deprive the appellant of a fair trial because, under the circumstances, the jury was adequately apprised that the State had the burden of proving the appellant’s guilt beyond a reasonable doubt. There was sufficient evidence from which the jury could conclude beyond a reasonable doubt that the appellant was the assailant and guilty of first degree criminal sexual conduct. The sentencing judge did not abuse his discretion by declining to depart from the presumptive sentence because the judge was sufficiently apprised of the facts and circumstances of the case.
Affirmed.
