ADA, Okla. (KTEN) — A Pontotoc County man is jailed pending charges from an investigation into the death of his brother.

On Friday, August 4, deputies were dispatched to a residence on County Road 1530, east of Ada, after receiving reports of shots fired around 8:30 p.m.

They found Paul Carpenter lying in a pool of blood inside the home.

"There were two small children in the residence at the time of the shooting," said Pontotoc County Sheriff John Christian. "I believe they observed, if not the shooting itself, but the deceased body on the floor, which was their grandfather."

John David Carpenter, the victim's younger brother, was also in the home. John Carpenter admitted to deputies that he had used a .22 caliber rifle to shoot Paul Carpenter.

"The person that was alive in the residence said that he had shot his brother due to his brother trying to kick the door in to his bedroom to make entry, and that he was in fear for his life," Christian said.

John Carpenter, 50, was arrested for previous warrants; and additional charges are pending as the Oklahoma State Bureau of Investigation reviews the case.

"Any time there's a homicide, or there's a deceased person — in this situation, somebody's been shot — I call in OSBI," Christian said. "They have the tools, the lab, the technicians to work a crime scene and do it thoroughly."

John Carpenter is being held at the Pontotoc County Justice Center on outstanding warrants, including a former felon in possession of a firearm along with pending charges linked to the homicide investigation. Bond was set at $250,000.
