Zachary Lee McCauley, 29, of Kentucky, was charged this week with trafficking a minor, sexual exploitation of a minor, criminal solicitation, and related crimes in connection with a sex trafficking scheme involving a 13-year-old Buckingham Township (Bucks County) girl, The Philadelphia Inquirer reported.

According to the story, the girl thought McCauley was a teenage boy when he befriended her on Snapchat last fall.

Over time, he persuaded her to send nude photos and videos and later created a fake dating profile for her on Grindr in which she pretended she was 18. Eventually he coerced her to have sex with two men who responded to the profile, police said, threatening to harm the girl’s mother if she didn’t comply with his demands.

The men who responded to the Grindr profile and sexually assaulted the girl—Jon Van Ingen, 67, of Doylestown, and Randy Quinn, 42, of Coopersburg, Lehigh County—have also been arrested and charged with statutory sexual assault. They were released on $150,000 unsecured bond, The Inquirer said.

The investigation began when the girl’s mother contacted police after seeing news reports in February about Matt Wills, a Hulmeville man charged with producing child pornography and sharing it online. The mother was also concerned after she caught her daughter taking risque photos, at which point she confiscated her iPhone.

A month later, the mother found pornographic pictures of her daughter and messages from McCauley on the girl’s new phone.

The girl met with Van Ingen twice in October, and on their second meeting, the two had sex in the back of his truck while it was parked in a school parking lot, The Inquirer said. Quinn had sex with the girl twice, once in a park and another time in a motel in Doylestown. Both occasions were streamed to McCauley through Snapchat.
