A man was shot and killed in an argument at a home north of Willow.
Alaska State Troopers say 61-year-old Ronald Gunter was struck in the head when a man he was arguing with pulled out a pistol.
Troopers told the Anchorage Daily News (http://bit.ly/su0kTc) that the man fired a single shot Sunday night, apparently in an attempt to try and put a stop to the fight.
Prosecutors reviewed the case and made a preliminary decision not to arrest the suspected shooter.
Troopers say the investigation is continuing.
