Middlesex District Attorney Marian Ryan said an investigation has found that two officers who shot and killed a suspect in Lowell, Massachusetts, were justified in the use of deadly force.
Jose Perez, 39, of Lowell, was shot and killed by police after he charged at officers with a knife and meat cleaver on Cambridge Street on March 26. Two 911 callers said Perez was "threatening to kill everyone."
Ryan said the investigation conducted by her office, Massachusetts State Police and Lowell Police also determined that there was no criminal conduct involved in Perez's shooting.
