The suspect who allegedly shot a New Hampshire police officer has been killed in a gunfight with authorities, officials said Sunday.

Matthew J. Masse, 38, allegedly opened fire on family members and the responding officer Saturday afternoon in Raymond, sparking a massive manhunt that included road closures and a shelter-in-place order.

“There was an exchange of gunfire between Mr. Masse with his rifle and the officers,” the state Attorney General’s Office said. “Following that exchange, Mr. Masse was found deceased by officers when they approached his location.”

An autopsy has been scheduled for early this week to confirm his cause and manner of death, the office added.

The incident erupted shortly after 1:30 p.m., when Masse reportedly shot his relatives with a long gun and then fired at responding police. A Nottingham Police Department officer was hospitalized with non-life-threatening injuries, officials said.

The suspect — described as a middle-aged white male who is 5 feet, 11 inches tall and weighs 202 pounds — reportedly had active felony warrants for attempted arson at his family’s home on Thursday.

After the shooting, Masse fled into a wooded area, triggering a large-scale manhunt, officials said, and K-9 units were deployed and officers were “working feverishly with other agencies” in an all-hands-on-deck search.

During the attempted arrest, an exchange of gunfire broke out. Authorities later found Masse dead at the scene, with his long gun recovered nearby.
