A jury found a Morris County man guilty Thursday of sexually assaulting an 11-year-old girl during a sleepover at his home, authorities said.

Richard Perry, 48, of Oak Ridge was found guilty of two counts of sexual assault and endangering the welfare of a child, the Morris County Prosecutor’s Office announced Friday.

Perry’s crimes occurred on Oct. 2, 2016 when he touched the niece of a friend on the breasts and vagina during the sleepover, according to a release from the prosecutor’s office.

The girl immediately told her aunt that Perry touched her and the aunt contacted the police, officials said.

Perry is scheduled to be sentenced on Jan. 17, 2020, when he will face a minimum sentence of five years in state prison. He must also register as a sex offender.
