Officers said the shooting happened inside a home where two children were playing and one of them got ahold of a gun.

“It appears at some point, a small child found a gun, pointed the gun at a sibling, and accidentally shot the sibling," said MSgt. Gary Knight with the Oklahoma City Police Department. “It’s heartbreaking when anyone innocent gets hurt, but especially a 4-year-old child."

Emergency responders arrived after a caller told 911 dispatchers that the young child had been shot.

“The one who was shot is 4 years old, he was critically wounded, he was transferred to OU Medical Center, Children’s Hospital," Knight said. “This is a tough one for people to work and see," Knight said.

There are many unknowns about the incident, such as who was at home with the kids and who called 911 to report the situation.

“It’s unclear exactly what all circumstances led to the small child finding a gun, that’s something we’re still looking at," Knight said.
