A 16-year-old girl was assaulted and killed by a classmate Friday morning at a Milford, Connecticut, high school, authorities said, reports CNN.
The attack occurred in a hallway at Jonathan Law High School around 7 a.m. and was witnessed in part by a school staff member, who attempted "life-saving measures" with others, Milford Police Chief Keith Mello said.
Maren Sanchez, a junior, was pronounced dead at Bridgeport Hospital at 7:43 a.m., Mello said.
The police chief didn't provide a motive but said investigators are looking into rumors a boy was angry because Sanchez had declined to go to the prom with him. The prom, scheduled for Friday night, has been postponed.
