A 15-year-old boy and his 14-year-old stepbrother were playing with a revolver when it apparently accidently fired, critically wounding the younger teen in the head Sunday morning in southeast Houston, officials said.

The shooting happened about 11:40 a.m. at a home in the 8100 block of Bonner near Bliss, according to the Houston Police Department.

Police said the wounded teen was rushed to Ben Taub General Hospital and was in critical condition.

The other boy was not hurt.

Police said the older stepbrother initially told investigators a man had come into the home, shot the younger teen and then left.

However, police said, the older boy later admitted that he had found a handgun and he and the other teen were handling it. He had his finger on the trigger when he handed the gun to his stepbrother and the trigger was accidentally pulled. The revolver fired.

The boy said he tossed the gun into a nearby body of water after the shooting. The HPD Dive Team has so far been unable to find the weapon.

Police did not release details about where the boy said he found the revolver or where he had tossed it.

The older teen was questioned and released to his parents.
