Authorities: Hofstra Student Was Killed by Police Authorities say a police officer's bullet killed a New York college student during the response to a home invasion at an off-campus home. Nassau County homicide squad Lt. John Azzata said Saturday night that Andrea Rebello was killed by a police officer as she was being held in a headlock by a masked intruder. Nassau County Police Department/AP Photo Azzata says the police officer opened fire as Dalton Smith made a motion to fire at the officers early Saturday morning. Azzata says the officer fired eight shots, hitting Smith seven times and Rebello once in the head, killing her. Earlier Saturday, police said Smith had an extensive criminal history and was wanted on a parole violation related to a first-degree robbery conviction.
