Tl;dr: 75-yo old woman attacks the employees over a sandwich, rips hair from one of them, put that hair in her purse, calls the police and dies.

At that point, two other employees intervened, and as they were pulled apart, a “chunk of hair” was pulled from the shift lead’s head, “leaving a raw area.”

Once separated, the employees got behind the counter and Grayson sat down, taking a phone call. She was seen picking up the shift lead’s hair and putting it in her bag, police said.
