A teen girl asks her boss to be moved off the late shift at Burger King because she is afraid. Just before that change is set to take place, 19-year-old Kristal Bayron-Nieves is shot and killed during a robbery. An armed and masked robber enters the restaurant at 116th Street and Lexington Avenue, around 1 a.m. demanding cash. He is given $100. He then shoots the teen in the stomach, killing her, pistol-whips a male customer before punching a female manager in the face, according to police said. No arrests made so far.
