VERNON — A fire that destroyed the garage where a township woman was found beaten to death just days after that crime has been ruled suspicious, a fire investigator said Saturday. The fire late Thursday destroyed the garage at 4918 Bushnell Campbell Road where Tricia Wade, 31, was found June 27 bludgeoned to death. Her boyfriend, Nathan A. Riggs, 26, is being held in the murder. Saturday Vernon Township fire Chief Lawrence Foltz said no one has been living at the home since the murder. Now investigators from the Trumbull County Sheriffs Office, the state Fire Marshal’s Office and his department are looking into the cause of the blaze. The fire gutted the garage, which was unattached to the mobile home at the address. Yellow crime scene tape surrounded blocked off the garage after the fire which came the same day a Trumbull County Grand Jury indicted Riggs on charges of aggravated murder and gross abuse of a corpse. Deputies arrived about 4 a.m.
