Search warrants returned in sex abuse case against University of Oklahoma social work professor

According to court records, Pellebon had been the subject of a DHS investigation in 2001.

A “restricted” report completed 10 years ago by the state agency revealed Pellebon had been suspected of inappropriate conduct with a former Norman police officer's daughter.

Records show the suspect would lie in bed with the girl, who was 11 at the time, with the door closed when the officer wasn't home.

DHS closed the investigation as “unfounded” when the officer's daughter failed to give a statement.

The Norman Police Department never investigated Pellebon's alleged behavior in 2001, court records show.

The police officer said he and Pellebon had become friends through church, but that the DHS inquiry had caused a “rift” between the two men's families.

The officer also reportedly told investigators the suspect's ex-wife, Champa Pellebon, called his family shortly after the 2001 investigation and told them she had found child pornography on her then-husband's computer.

Pellebon, who is on paid leave from the university, is free on $75,000 bail. He has not returned phone messages and emails seeking comment.
