The young girl told the adult that Talbert made her take all her clothes off for the "oil rubdown" and then sexually assaulted her, police said.
The woman contacted police and investigators spoke to the now 14-year-old girl. She told officers the abuse started when she was 12 years old.
She claimed Talbert also sexually assaulted her in public, in the shower at Cross Creek park and gave her multiple oil rubdowns.
Houston Borough, Oakdale Borough and the Washington County Sheriff's Office all told WPXI that Talbert doesn't work there anymore.
He's still listed on the website for the Pittsburgh Technical College as one of its public safety officers, though the chief of police told WPXI he doesn't work there anymore either.
Talbert, 56, is charged with felony rape of a 12-year-old and involuntary evident sexual intercourse.
According to the criminal complaint, the victim told police Talbert had photos of another girl on his phone. No word from troopers if there could be more charges filed in the case.
