According to the criminal complaint, the victims’ mother told investigators the assaults happened in August or September of 2016 while Petrill was staying in her family’s apartment.

Police say he was a friend of her boyfriend, and the couple was not aware that Petrill was a registered sex offender.

She also told police that one of her sons “was left alone with Petrill several times.” Petrill stayed at the family’s apartment for about one week.

The victims, ages 13 and 15, had been diagnosed with autism and have limited ability to communicate. The boys’ mother told police she had no idea the boys had been abused.

“Something came to light at a doctor’s appointment,” Greensburg Police Capt. Robert Stafford said.

Police say Petrill has prior convictions for indecent assault in 2000, 2002 and 2005. He also has prior arrests for failure to comply with registering as a sex offender in both 2014 and 2016.

Authorities believe he may be staying in Philadelphia and has ties to Westmoreland County.

Anyone with information on Petrill’s whereabouts is asked to the City of Greensburg Police at 724-834-3800.
