A former Jay High School custodian confessed to authorities he molested a 16-year-old student multiple times over the past six months on school grounds, a prosecutor said Friday.

Adam Wolfe, 45, of Jay, is charged in Delaware County District Court with four counts of second-degree rape, three counts of second-degree rape by instrumentation, three counts of forcible oral sodomy and three counts of sexual battery, Assistant District Attorney Nick Lelecas said.

Wolfe was in jail Friday in lieu of $730,000 bail.

Wolfe was suspended from his job, and then resigned, Jay Police Chief Mike Shambaugh said.

According to an affidavit for his arrest, Wolfe initially befriended the teen and gave her gifts of candy and soda.

He is accused of raping her beginning in December in the art classroom, his custodial office and the computer classroom, the affidavit states.

Wolfe told authorities the victim "just makes me weak” and he was "unable to resist her.” The victim repeatedly "objected to each one of his (Wolfe) sex acts” and at times Wolfe did stop because he felt guilty the victim was crying out "that what he was doing to her was hurting her,” authorities said.
