OPINION
BUSSEY, Judge:The appellant, Clark Allen Davis, was convicted of three (3) counts of the crime of First Degree Rape, After Former Conviction of a Felony, in the District Court of McIntosh County, in Case No. CRF-83-122 and was sentenced to thirty (30) years’ imprisonment for each of the three counts, and he appeals.
On August 24, 1983, R.N., J.H. and R.G., all of whom were sixteen (16) years old, ran away from the United Methodist Children’s Home and hitchhiked to R.G.’s aunt’s house. R.G.’s aunt and her common law husband, later identified as the appellant, were the only people in the house. After appellant ate a meal, the five watched television for awhile and then went to a truck stop. The aunt and appellant told the three girls to go inside and flirt with the men and sleep with them for money. At this point, both R.N. and J.H. observed a gun in the aunt’s purse. None of the girls solicited anyone while at the truck stop; thus, after a short while, they left the truck stop and returned to the house. Once they were back at the house, they watched television for awhile, and then decided to go to sleep. The girls changed into nightgowns, and J.H. and R.G. went into the back bedroom. Appellant told R.N. to stay in the living room with him. Appellant then told R.N. to lay down on the couch, and appellant had intercourse with her notwithstanding the fact that she said no and tried to push him off. R.N. testified that she did what he said because she was afraid of the gun that was in the purse a few inches away. *848Subsequently, R.N. went back into the bedroom and went to bed. Later the same night, appellant came into the room and again had intercourse with R.N. against her will. He then got on top of J.H., who was sleeping in the same bed, and had intercourse with her against her will. Appellant left the room, but returned once again toward morning and raped R.N. for the third time. When appellant departed for the last time, the two girls got dressed and left the house.
The girls were later picked up by the police for hitchhiking, and R.N. was returned to her mother. Later, she was transported to an Oklahoma City hospital where she was examined by a doctor. The examining physician testified that she examined R.N. and found non-mobile sperm from a vaginal washing.
The State also presented the testimony of a criminologist with the Oklahoma State Bureau of Investigation (O.S.B.I.) who testified that he analyzed the contents of the rape kit and the blood type of R.N. and appellant and determined that only twelve (12) men out of one hundred could have perpetrated the crime, and that appellant was included in that group.
An O.S.B.I. agent testified that he questioned appellant on October 14, 1983, and that at that time he advised appellant of his Miranda rights. He stated that appellant basically told his side of the story during the interview.
Appellant’s chief witness was Carolyn Stevens, R.G.’s aunt, and she testified that she slept with appellant on the night of the crimes, and that nothing happened in her house that night or she would have heard it. The appellant did not testify.
For his first assignment of error appellant contends that he did not have a public trial in violation of his rights under the Sixth Amendment to the United States Constitution in that spectators were excused from the courtroom during the testimony of the victim, R.N.
While it is true that there is a strong preference for public trial, this preference does not preclude a limited closure from the public where there is a clear need for excluding certain persons or classes. Neal v. State, 86 Okl.Cr. 283, 192 P.2d 294 (1948); Shipman v. State, 639 P.2d 1248 (Okl.Cr.1982).
In the instant case, the trial judge cleared the courtroom of spectators only during the testimony of R.N. In granting the prosecution’s motion to clear the courtroom during her testimony, the trial court stated:
Court will grant the motion and exclude the general public for the following reasons for cause; one, the age of the alleged victim is fifteen years if she was in a juvenile proceedings the public would be excluded anyway; secondly, the defendant will have a right to confrontation, the jury will be there and can observe the demeanor and trustworthiness of the witness and I don’t see that the defendant is prejudiced by it; exceptions allowed. (Tr. 7.)
After a thorough examination of the record before us, we are of the opinion that the trial court did not abuse its discretion in granting the prosecution’s motion, since the closure was carefully limited, and the appellant suffered no apparent prejudice. Accordingly, this assignment of error is without merit.
The appellant also alleges that he did not have a public preliminary hearing in violation of his right to a public trial. However, we reject this contention for the same reasons stated in our analysis of the first assignment of error.
Next, appellant argues that the trial court erred when it failed to suppress agent Hogan’s testimony concerning his custodial interrogation of appellant because his attorney was not present during the interrogation. We disagree.
In the present case, agent Hogan testified that when he interrogated appellant he informed him of his Miranda rights, and that appellant stated that he understood them, and waived them. Moreover, none of the statements made by appellant were in*849criminating, but were simply a recitation of his version of what transpired on the night of the crimes. Appellant suffered no prejudice as a result of the admission of the testimony; consequently, any error was harmless. Selsor v. State, 562 P.2d 926 (Okl.Cr.1977). We find no error.
In another assignment of error appellant maintains that the serologists probability testimony was without foundation and so prejudicial to appellant that his conviction must be reversed. However, appellant failed to interpose a timely objection to this testimony at trial; thus, the alleged error was waived. Roberts v. State, 568 P.2d 336 (Okl.Cr.1977).
As his fifth assignment of error, the appellant contends that the evidence is insufficient to support his conviction. When the sufficiency of the evidence presented at trial is challenged on appeal, the proper test is whether, after viewing the evidence in the light most favorable to the State any rational trier of fact could have found the essential elements of the crime beyond a reasonable doubt. Jackson v. Virginia, 443 U.S. 307, 99 S.Ct. 2781, 61 L.Ed.2d 560 (1979).
In the present case, both victims testified that appellant had sexual intercourse with them against their will. The testimony of each victim corroborated the testimony of the other. Additionally, the testimony of the examining physician was that he observed non-mobile sperm in a vaginal washing obtained from R.N. Viewing this evidence in the light most favorable to the State, we find that a reasonable trier of fact could have found the elements of first degree rape beyond a reasonable doubt. This assignment of error is without merit.
As his final assignment of error, the appellant alleges that the State improperly introduced evidence of other crimes. He argues that the State erroneously put on testimony that appellant took the victims to a truck stop for purposes of prostitution. However, this assignment was not properly preserved for review by this Court in that no objection was made to this testimony at trial. See Boyd v. State, 572 P.2d 276 (Okl.Cr.1977). This assignment of error is without merit.
Accordingly, the judgments and sentences are AFFIRMED.
