Fred and Willie Green are recovering Friday afternoon after police say their grandson beat the couple Friday morning with a wooden dowel and then fled the scene. It happened at the Greens' home on County Road 90 in Celina.
Authorities are not sure what caused the argument that sent their 21-year-old grandson Preston Boan over the edge. They did say he beat both of them severely.
Seventy-four-year-old Fred Green is listed in fair condition at a Presbyterian hospital in Plano, and his 78-year-old wife, Willie Green, was carelifted to Baylor Medical Center in Dallas. Her condition is unknown as of Friday afternoon.
Boan is still on the loose, and police are asking for help from the public.
The suspect is said to be driving a white 2004 Ford Ranger pickup with Texas license plate numbers 88B-BG5. If you have any information you are asked to call the Collin County Sheriff's Department at 972-547-5350.
The Collin County Sheriff's Department is still investigating into what led to this bizarre chain of events.
