ALLENTOWN, Pa. (AP) — Police say an 86-year-old man is behind bars after fatally shooting his son at the eastern Pennsylvania home they shared.

Allentown police say Roy Tarboro shot and killed 54-year-old Rickey Tarboro on Monday evening in the midst of the megastorm that slammed the region.

Roy Tarboro was arraigned on homicide charges and held without bail.

Police did not discuss the circumstances of the shooting but Rickey Tarboro’s live-in girlfriend tells The Morning Call of Allentown the older man had dementia.

It was not immediately clear if Roy Tarboro had an attorney.
