COLUMBUS, Ohio — Female students were being paid for sex at the high school where two boys assaulted a developmentally disabled classmate in the auditorium, a social worker claims in a police report.

The social worker learned of the situation through a girl who said she had been paid to have sex with boys at Mifflin High School, according to the report obtained by The Columbus Dispatch on Tuesday.

A week before the developmentally disabled girl was assaulted March 9, the social worker told an assistant principal about the student’s claims, which included girls prostituting themselves for $10 in the auditorium and allowing sex acts to be videotaped, the report says.

The assistant principal, Vincent Clarno, “smirked and said he hears crazy stories all the time,” the report says.

Clarno was assigned to another school by Superintendent Gene Harris after the assault was reported to police by the girl’s father. Clarno declined to comment about the police report when contacted by The Dispatch.

The school investigator “was given that information and he tried to substantiate it, and was not able to do that,” Harris said.

The report was released the same day a teenager who pleaded guilty in the case was ordered to remain in a juvenile detention center.

Franklin County Juvenile Magistrate Douglas Shoemaker said the Ohio Department of Youth Services can hold 16-year-old Timothy Armistead until he is 21 if he does not cooperate with officials.

Armistead is serving an 18-month sentence for felonious assault after he pointed a gun at and threatened a person in July.

Prosecutors said Armistead and another student, Brandyn Hobbs, 15, forced a 16-year-old girl to perform oral sex on them while another student videotaped.

Prosecutors dropped charges of rape, kidnapping and sexual battery as part of a plea deal after the girl’s family decided they did not want her to have to testify. Hobbs and Armistead pleaded guilty to delinquency counts of felonious assault in November.

Hobbs is to be sentenced Feb. 9. Franklin County Prosecutor Ron O’Brien has said the teen likely will receive probation.

Both teens were expelled, and the girl now attends another school.

Regina Crenshaw, who was fired from her job as Mifflin’s principal, has been charged with failing to report a sex crime, a misdemeanor.

Some teachers and administrators, including Crenshaw, have claimed there was an unwritten school district rule that discouraged employees from calling police to avoid media attention, which the district has denied.

Crenshaw’s attorney, Toki Clark, said her client did not know about the social worker’s claims.
