Authorities in Waupaca County have released the identity of a man fatally stabbed in Iola last month. 42 year old Bradley Trinwith of Mukwonago died at Waupaca’s ThedaCare Hospital after being stabbed in the neck during a fight, according to a criminal complaint. 23 year old Tyler Knutson of Iola has been charged with first degree intentional homicide in the death. The complaint says the fight followed a road rage incident near downtown Iola. Both Knutson and Trinwith were passengers in the vehicles involved. Those vehicles pulled into nearby driveways where the fight ensued. Knutson is alleged to have pulled out a pocket knife and stabbed Trinwith. Knutson and his family argue he was acting in self-defense. Knutson is being held on 500-thousand dollars cash bond. He is due back in court next Tuesday.
