PETERS TOWNSHIP, Pa. — Hundreds turned out Sunday at Trinity United Methodist Church in McMurray for a candlelight vigil honoring 18-year-old Karoline Heintz. The Peters Township graduate, who was preparing to begin her freshman year at PennWest California, was killed Wednesday night. People leaving the church described the service as somber but fitting. “Karoline had a lot of support from the community,” said Alexandra Brooks, who works for Domestic Violence Services of Southwestern PA. “It was really clear that there were a lot of people who knew her, but it was also very clear that there were a lot of people who were here to support the family and support her.” State police say Heintz’s boyfriend, Royce Moser, stabbed and killed her following an argument. Authorities allege he then recruited his mother, Rachel Moser, to help move Heintz’s body and clean up the crime scene. In a statement released last week, Heintz’s family said “This is a parent’s worst nightmare. Karoline was loved by all. She was a kind, smart, beautiful girl. We want justice for our ‘sweet’ Karoline.” Sunday’s gathering was one of two vigils held in Heintz’s memory. A church in Elizabeth Township also hosted a vigil Sunday evening.
