A Kearney man will have surgery on an eardrum damaged by a blast of illegal explosives before he begins his jail sentence. 31-year-old Scott Rhone was sentenced to 30 days in jail and three years of probation for felony possession of a destructive device on Tuesday. He also was sentenced on two drug counts. Authorities say Rhone was injured when he ignited a metal tube filled with powders he purchased at a gun show. Rhone told the judge the surgery is scheduled for next month, so the judge ordered Rhone to report to Buffalo County Jail on Jan. 7.
