State Police say the man killed Thursday afternoon in an armed confrontation with Troopers was 61 year old John Knudsen. He was shot and killed after he fired a shot from a handgun in the direction of troopers, who were outside his HOLLIS home. Knudsen came to the front doorway of his house, made comments to police, and then fired a shot. Trooper Tyler Stevenson returned fire and shot Knudsen. Stevenson is a nine year veteran of the State Police and a member of the tactical team, which had responded to the scene, along with negotiators. As is standard procedure, Stevenson was placed on administrative leave with pay.
