Lt. Doug Nolte says the man was found dead in the backyard of the house in southeast Wichita on Monday night.
He is the same age as a man who was arrested Sunday when the boy was taken to a hospital after he was grazed by a bullet. The child was treated and released.
Police allege the man began playing “quick draw” with two boys, using his .22 caliber handgun, and accidentally fired a shot. A 14-year-old boy was not injured.
