Kelvin James Coker, the 60-year-old father, arrived at his son’s home armed with a handgun and confronted him about the earlier shooting, the report said. The son reportedly aimed his shotgun at his dad who was inside a truck at the time. His father "drew his handgun, fired a shot and struck Nicholas." The 32-year-old, who was reportedly hit in the torso, returned fire and hit his father in the neck. Both died at the scene. The report said that deputies have been called to the family property in Wagarville over the years and as recently as last week.
