Just a few years before Paris Hilton was sent to a school for troubled teens in Southern California in the mid-1990s, a convicted child rapist and child killer was suspected in the disappearance of two boys at the school.

Her documentary, “This is Paris,” shines a light on “therapeutic” boarding schools and the abuse some students — like Paris — say they suffered in them. They are using the hashtag #breakingcodesilence to draw attention to the issue.

The first school that Hilton was sent to, CEDU in Running Springs, Calif., may have been a hunting ground for James Crummel, a convicted child rapist and murderer. For awhile, before he hung himself in prison in 2012, California Department of Justice investigators were looking into whether Crummel was responsible for the disappearances of at least two boys from the school, according to the Alpenhorn News in Running Springs.

“That’s also what we heard,” Adam Eget, coordinator for the Comedy Store in LA and a former student at CEDU told The Post. “They think a few kids there were murdered by Crummel.”

Eget told podcaster Joe Rogan about his experiences at what he called the “cult” in May. He said that Hilton reached out to him after.

Crummel lived with a Newport Beach, Calif., psychiatrist, Burnell Forgey who was contracted to the CEDU school in Running Springs. At least two kids disappeared from the school during the time Crummel was visiting Forgey, who is now deceased. The school closed in 2005.

A California Department of Justice investigator was reportedly looking into the case in 2009. The DOJ did not return calls as to the status of the case.
