Police say a chainsaw-wielding Tennessee father had to have his leg amputated after his son ran him over with a lawn mower.
Officers were called to a home in Bristol, Tennessee, and found 76-year-old Douglas Ferguson bleeding from his head and leg.
A preliminary investigation indicated that he tried to attack his son with a running chainsaw while his son mowed the yard. His son, who was not identified, ran over his father with the lawn mower as a way to defend himself.
Detectives said the father and son had an ongoing feud.
Ferguson was charged with attempted second-degree murder and violating probation.
