Jonathan P. Ryker, a coach at Rockstar Cheer in Southampton, became the center of an investigation in August 2022, when authorities in Medford Township got a tip that he sent explicit content to a minor on social media, New Jersey State Police said.
During the 8-month investigation, detectives were able to identify another one of Ryker's victims — also a student at Rockstar Cheer, police said.
Ryker was charged with sexual assault, endangering the welfare of a child, and aggravated criminal sexual contact. He was lodged in Burlington County Jail pending a detention hearing.
Ryker is active on TikTok, where he shares cheer content with his 25.1K followers.
