A suburban Philadelphia high school senior posed as a teenage female to get more than 100 fellow teens to send him nude photos of themselves, officials said Thursday.

Monsignor Bonner Catholic High School student Derrick Jones targeted boys – some in middle school – by leading them to believe they were communicating with a girl named “Haley” through various social media channels, according to Delaware County District Attorney Jack Whelan and Darby Township Police Chief Regina Price.

Jones, an 18-year-old from Glenolden, used platforms such as Instagram, Kik, WeChat and Snapchat, was found when investigators tracked his IP address. Even after he spoke to authorities, he continued to target victims, officials said.

Investigators said Jones targeted 136 people – about 60 of whom are identified as local males. Once he had the nude photos, Jones posted them from fake accounts in hopes to extort more photos from the victims; he sent graphic images to one of the victim’s own family to shame him, officials said.

“Haley” is a real girl who had her identity stolen by Jones, investigators said.

A judge on Thursday arraigned Jones on dozens of counts, including child pornography and harassment. Jones posted $5,000 bail. He couldn’t immediately be reached for comment.

Jones faces expulsion from school, Whelan said.
