Police say a Knoxville man who successfully sued one of his sons for the shooting death of his wife has been assaulted by his other son. 55-year-old Billy Dean Carter was arrested Wednesday (7/1) and charged with assaulting his father, 74-year-old Bill Carter. Police say the younger Carter knocked his father to the ground and kicked him twice on a road near the elder Carter’s home following an argument. You might remember that in 2017, a jury ordered another of Bill Carter’s sons, Jason Carter, to pay $10 million to the estate of his mother, 68-year-old Shirley, who died in 2015 from two gunshot wounds fired by a rifle. Jason Carter was later acquitted of murder in the case.
