A former Central Bucks School District substitute teacher faces 15 to 30 years in federal prison after his arrest on child pornography charges.

Eric Sanville, 39, of Norwood in Delaware County, was taken into federal custody Thursday, Aug. 27, on a charge of manufacturing and attempting to manufacture child pornography, according to a criminal complaint filed in the U.S. District Court for the Eastern District of Pennsylvania. Sanville worked as a long-term substitute in the Central Bucks School District from 2013 to 2016, the Bucks County Courier Times reported.

He most recently worked as a special education teacher at Gwynedd Square Elementary School in Lansdale, part of the North Penn School District in Montgomery County.

Federal prosecutors allege Sanville used two Snapchat accounts to pose as a 13-year-old boy and solicit sexually explicit images from girls ages 9 to 13. The investigation began after the National Center for Missing and Exploited Children forwarded multiple Cyber Tipline reports to authorities in July and August 2025.

According to the criminal complaint, Sanville allegedly chatted with about 25 individuals who identified themselves as minors. He allegedly told them he wanted to start a group chat for kids ages 9 to 13 and asked them to send nude photos before he would grant access.

Two victims are described in the complaint. One, who lives in Sweden, told investigators Sanville directed her how to pose for photos and videos. She believed she was communicating with a 14- or 15-year-old boy. A second victim told investigators that when she said she just wanted to chat, Sanville replied he was looking for "more than that" and asked her to show more of her body, according to the complaint.

FBI agents interviewed Sanville while executing a search warrant at his home on Aug. 27. He allegedly admitted to using Snapchat accounts to contact underage girls and to portraying himself as a teenage boy, according to the complaint.

He remains in custody.

The Central Bucks School District has not issued a public statement about Sanville's prior employment. Authorities have not indicated any Central Bucks students were among the alleged victims.

The North Penn School District posted a statement on its website Thursday night confirming the educator had been placed on leave, barred from district property and told not to contact students. The district said authorities found no evidence that North Penn students or district technology were involved.

Sanville had his first court appearance Thursday, according to CBS News Philadelphia. No date for a grand jury proceeding has been announced.
