A Waterloo man has been found guilty in the murder of a Grundy Center man in Floyd County, according to KWWL. 29 year old Armando Adame III was found guilty Wednesday for the October 25, 2017 murder of 27 year old Michael Johns. Adame and Johns were driving around when they began to argue. Eventually Adame stopped on a gravel road, pulled Johns from the car and shot him in the head with a sawed off shotgun. Adame faces a mandatory sentence of life in prison without parole when he is sentenced at a later date.
