HARTFORD, Conn. (AP) - A 16-year-old girl was stabbed to death inside a Connecticut high school Friday, and police took a teenage boy into custody and are investigating whether the attack stemmed from her turning down an invitation to be his prom date.

Emergency responders were called to Jonathan Law High School in Milford, about an hour's drive from New York City, around 7:15 a.m. Staff members and paramedics performed life-saving measures on the girl, but she was pronounced dead shortly before 8 a.m. at Bridgeport Hospital, police said.

A 16-year-old boy was taken into custody. His name wasn't released because of juvenile offender laws, said Police Chief Keith Mello. Investigators are looking into reports that the boy stabbed the girl after she declined to be his date for the junior prom, which had scheduled for Friday night but was postponed because of the stabbing.
