Pennsylvania University soccer star Karoline Heintz and her boyfriend Royce Moser were having a discussion about their relationship when, according to Royce, Karoline said something that made him mad. Royce excused himself, telling Karoline, he has something for her, and goes inside his father's house. When he returns to Karoline, he stabs her in the chest with a knife. Joseph Scott Morgan and Dave Mack talk about the case of the mamma's boy who stabs his girlfriend then runs to his mother for help cleaning up the mess....all the while claiming "the devil made me do it".
