Hit by a Truck at Age Three
Kinison wasn’t like his brothers, probably because of the accident he had when he was three. Kinison got hit by a truck when he was only three years old, and the result was that it left him with “40 percent brain damage.” His parents were told that their son had mal epilepsy, but he didn’t have any seizures.
