Ex-Boy Scout Explains Why He Murdered Scout Leader.

You Won’t Believe How The Court Reacts!

A New Jersey man admitted in court to fatally stabbing the Boy Scout leader who he says repeatedly molested him as a child — to thunderous applause in the courtroom.

Clark Fredericks pleaded guilty Wednesday in Newton, N.J., to passion provocation manslaughter in the brutal slaying of retired correction officer Dennis Pegg three years ago.

Pegg was stabbed more than 20 times in his neck, chest and stomach, authorities say.

“From the time I was 8 years old until I was 12 years old, I was sexually assaulted and raped by Dennis Pegg,” Fredericks told the court in his impassioned plea, CBS in New York reported.

“It started with him wanting to touch my scar that I had through open-heart surgery at the age of 6,” Fredericks continued. “It progressed to wrestling matches and eventually led to him raping me.”

Fredericks told the court that Pegg had told him he had sexual relations with one of Fredericks’ friends, who would later commit suicide in 1983, CBS reported. Fredericks said that Pegg, a “respected law enforcement officer,” threatened to kill him if he “told anyone about our secret,” CBS reported.

Child pornography was found on Pegg’s computer, NJ.com reported.
