A manhunt was underway Sunday for a 23-year-old Connecticut man who police say attacked three people in the past two days, killing two of them.

Peter Manfredonia, of Newtown, was believed to be armed, state trooper Christine Jeltema told reporters at a news briefing Sunday afternoon.

“At this time we do not believe he is in the area,” Jeltema said.

Family identified Ted Demers, an artist and Marine veteran, as the person who was killed and said he and Manfredonia were strangers, WFSB-TV reported.

The station quoted Demers’ wife as saying her husband went to his barn to look at a motorcycle belonging to the suspect.

Jeltema said overnight Saturday, Manfredonia stole shotguns, a handgun and a truck from the owners of another house in Willington. That person, a man, was not hurt, she said.

The trooper said the truck was found crashed and abandoned in Derby on Sunday morning.
