New Hampshire State Trooper Nathan Sleight justified in using deadly force against John Madore, who killed a security guard before being shot.

New Hampshire State Trooper Nathan Sleight was justified in using deadly force to fatally shoot John Madore at New Hampshire Hospital in November, according to a report by the state attorney general. The incident occurred after Madore, a former patient at the hospital, killed a security guard, Bradley Haas. The report states that Sleight's conclusion that Madore posed an immediate deadly threat was "objectively and reasonably sound." Madore had a history of mental health issues and had previously been a residential treatment patient at the hospital.
