A onetime-senior state parole officer – who oversaw parole officers who supervised sex offenders – pleaded guilty on kiddie porn charges in Brooklyn federal court today, authorities said.

James Leone, 50, was arrested at his Long Island home in September after federal law enforcement agents searched his computer and found graphic photos and videos of children being abused, according to court documents.

Leone pleaded guilty to accessing child pornography with intent to view, confirmed Robert Nardoza, a spokesman for the US Attorney’s Office in Brooklyn.

He faces ten years in prison.

Before he became a parole officer, Leone worked as a New York City child abuse investigator, according to court documents.

The images Leone downloaded depicted girls ten or 12 years old being sexually abused by their parents and brother, according to court documents.

Leone remains in home detention on $500,000 bond, court documents and Nardoza said.

A woman who answered the phone at Leone’s home in Bethpage said he wasn’t there and said, “I don’t think he’s going to be talking to any reporters today.”
