Authorities captured Preston Boan, a 21-year-old Celina man who severely beat his own grandparents with a wooden dowel last week, in Caddo County of western Oklahoma just after five o'clock Thursday morning. Witnesses said he had been staying in a roadside park for the past two days.
He is being held at the Caddo County Jail awaiting extradition back to Celina, Texas.
Police say that's where Boan lived with his grandparents, Fred and Willie Green, until he snapped last Friday.
Police also recovered the truck he was driving. There is still no word on a motive for this violent crime.
