Fatal Attack and Immediate Aftermath
Eighteen-year-old Royce Moser told Pennsylvania State Police that “demons” compelled him to stab his 18-year-old girlfriend, Karoline Heintz, a freshman defender on the PennWest California soccer team. Heintz arrived at Moser’s North Strabane residence on Wednesday night, was asked to wait in the driveway, and after a brief argument Moser entered the house, retrieved a kitchen knife and stabbed her in the chest. He placed her body in the rear hatch of her Jeep Cherokee and drove it to his mother’s home in Beallsville, where she helped clean the car, launder his clothes, and instructed him to shower before returning the Jeep to the scene near the California Borough library. Heintz’s body was discovered in the trunk early Thursday.
