Bucks County District Attorney David Heckler says the Middletown Township officer was justified in shooting 64-year-old Michael Devine inside his home in the early morning hours of Feb. 23.
Heckler said Wednesday that Devine reported a nonexistent burglary in order to get police to the house, then approached them with a large carving knife and threatened their lives.
Heckler said Devine had been depressed and family members had removed a handgun from the home over fears he might be suicidal.
