A Pennsylvania college soccer star was allegedly stabbed to death by her boyfriend, who claimed “demons” told him to do it — and got his mom to help him dispose of the body, according to police.

Karoline Heintz was found ᴅᴇᴀᴅ in the back hatch of her Jeep Cherokee at around 12:30 a.m. Thursday, just outside the Pennsylvania Western University campus in California, Pa.

Heintz, an incoming freshman on the university’s women’s soccer team, had met up with her boyfriend, Royce Moser, after she attended a family party earlier in the evening, Pennsylvania State Trooper Rocco Gagliardi told reporters.

The couple got together at Moser father’s home in North Strabane Township, where they began talking about their relationship inside her car before the discussion turned a “little bit south.”

“They’re a younger couple talking about how relationships can continue maybe in a college setting. Somewhere that conversation probably goes a little bit south,” Gagliardi said. “Towards the end of that conversation between boyfriend and girlfriend, he goes inside and grabs a large knife from the kitchen.”
