College soccer player allegedly killed by boyfriend who blamed ‘demon;’ his mom accused of cover-up

Karoline Heintz, an 18-year-old incoming freshman on the Pennsylvania Western University soccer team, was allegedly stabbed to death by her boyfriend Royce Moser, whose mother then allegedly helped her son after the attack.

Moser, 18, allegedly said during an interview with investigators that a “demon” took over and instructed him to stab his girlfriend, according to court documents.

Pennsylvania State Police said Heintz met with her boyfriend outside his father’s residence in North Strabane to talk.

“She spoke with him while sitting in her vehicle in his driveway. During the conversation he got angry by something she said to him, but he could not remember what. He then had a ‘demon take over’ him and tell him to stab Karoline,” the suspect allegedly conveyed during an interview with investigators, according to court documents.

“He told her ‘wait I have something for you’ and went inside of the residence to get a knife. He then came back outside and stabbed her in the chest. She fell out of the vehicle and he attempted to drag her to the back of her car. He put her in the back hatch of the vehicle and then got in the driver seat,” the criminal complaints say.

Authorities say the 18-year-old Moser then called his mother, Rachel, who allegedly proceeded to assist him after the stabbing.

Rachel Moser allegedly told him to come to her house. When he arrived, she allegedly told her son to pull the car into the garage and that she would help him clear the vehicle with disinfectant spray, according to court documents.

“She then gave him latex gloves and told him to follow her vehicle toward the university. They left the victim’s vehicle in the parking lot and he got in her car to leave,” the criminal complaints state. “She took the knife that was used to stab the victim and put it in a garbage bag to be put in the trash outside of her residence. She put his clothes into the washing machine.”
