New Facts: Moser Claims 'demon' Made Him Stab Heintz

Royce Moser, 18, stabbed his girlfriend, 18-year-old Karoline Heintz, in the chest during an argument outside his father's house. He later admitted he got angry and that a demon took over and told him to stab her.

After she fell, Moser put Heintz into the rear hatch of her Jeep Cherokee and drove to his mother's home; his mother cleaned the vehicle, provided latex gloves and followed the car when it was returned. An AirTag in Heintz's car showed it in a parking lot near the California Public Library; the vehicle was found with blood inside and outside and Heintz's body in the rear hatch.

The knife used was recovered in a garbage bag matching the description Moser gave, and surveillance captured Moser driving the victim's vehicle with his mother's car following. Royce Moser faces criminal-homicide and related charges; Rachel Moser faces counts that include hindering apprehension of a fugitive, and both are charged with tampering with evidence, abuse of a corpse and obstruction.
