A complaint filed Tuesday alleges the boy used a .22-caliber revolver to shoot the man Saturday in Delaware County in central Ohio.

The boy called police and calmly told a dispatcher about the shooting. His mother then took the phone and said between screams and sobs that she and her son had been threatened with a gun.

The Delaware Gazette reports a defense attorney said in court that the child doesn't have a history of violent behavior.

Defense attorney Michael Cox declined to comment to The Associated Press on Tuesday.

A judge has ruled to keep the boy in detention.
