He explained one of his guns was removed from a safe sometime this weekend after someone tried to break into his home. Samuel claims the unloaded gun was then returned to a safe.

“But it was unloaded, I mean the gun was not loaded. Unloaded,” he said. “I don’t know because I wasn’t there. The police are investigating everything and I just ran to the hospital, I don’t know what’s going on.”

Authorities say multiple guns were found inside the home. But it’s not yet clear how the boy got possession of the weapon that was used in the shooting.

The boy is charged with aggravated assault, reckless endangering and related offenses. His name hasn’t been released.
