BETHANY, Okla. (AP) — Police in suburban Oklahoma City say a 16-year-old boy facing a manslaughter charge claims he accidentally shot a younger teen while they played with a pistol, but that he initially said it happened in a drive-by shooting.

The shooting happened Sunday when the teens were alone at a home in Bethany, along Oklahoma City's western border. The Oklahoman reports the 15-year-old boy was shot in the chest and initially told police he didn't know who shot him. He died later a hospital.

The older boy later acknowledged that they had been playing with a gun. A court affidavit filed by police says the older boy said he did not know the weapon was loaded. He was arrested Monday on complaints of manslaughter and reckless conduct with a firearm.
