HOUSTON (AP) -
A suspected drug dealer has been arrested for the death of his 4-year-old son who Houston authorities say picked up his father's gun and shot himself.
Police determined the gun had been stolen in a burglary two years ago.
Twenty-year-old Marquiez Deshon Pratt is being held Monday under $50,000 bond on charges of injury to a child by omission and possession of a controlled substance with intent to deliver. A court appearance is set for Tuesday.
Investigators said Pratt was asleep Sunday when his son, Jaiden, picked up the .40-caliber semiautomatic pistol that was nearby and shot himself in the stomach.
Pratt was outside his apartment when police arrived, handed the boy to officers and ran back inside. Police who chased him found marijuana, crack cocaine, scales and other items.
