Karoline Heintz update: Who is boyfriend, Royce Moser? Charges against him and his mother Rachel in focus

Royce Moser, a young athlete, has been accused of fatally stabbing 18-year-old PennWest California soccer star Karoline Heintz. According to reports, he allegedly took his mother's help later to dump the body. Moser and Heintz were in a relationship, but Moser did not attend the same university as Heintz. Their relationship took a turn for the worse when Moser is said to have taken the conversation "a little bit south" and, upon returning to his home, allegedly stabbed Heintz in the chest with a large kitchen knife.

Following the incident, Moser drove the Jeep, in which Heintz had fallen out of, to his mother's house in Beallsville, Washington County. It is alleged that Moser's mother, Rachel Moser, helped him clean up the crime scene, including washing his clothes and the car with disinfectant spray. Rachel Moser claimed that her son was influenced by "demons" to commit the act, and she expressed remorse for her son's actions.
