FAIRBANKS - Alaska State Troopers have released the name of the officer who fatally shot a naked man holding a knife.
Officials say the trooper, Gary Tellep, and three medics responding to a 911 call Tuesday found Thom G. Gruenig with a knife in his hand. After Gruenig refused commands to drop the knife, Tellep fatally shot the man.
Authorities then discovered the body of Gruenig's 66-year-old mother, Kathryn, who had been fatally stabbed.
Officials say substance abuse may have been played a role in Gruenig's behavior. Troopers found thousands of small nitrous oxide containers in the home. Nitrous oxide, commonly used by dentists, can cause depersonalization, dizziness, euphoria and mild hallucinations.
