A man accused of starting a fire on purpose that killed a man in a Waterloo home has been found guilty. 59-year old John Walter Spooner had been on trial the last two weeks for arson, following an August fire that claimed the life of 60-year old Tony Grider. Spooner will be tried separately for first-degree murder at a later date and is set to be arraigned on those charges later this month. Waterloo Police say that he admitted details of the crime to others on scene. Additional video footage showed him carrying a gas can and lighter near the home when the fire started.
