If only there was a good young’un with a gun to stop the bad one with a gun. Boy, 6, kills his brother, 3, while playing with guns in a Chicago area home.

Moments earlier, a judge ordered Michael Santiago, 25, held on $75,000 bail on child endangerment charges stemming from the shooting Saturday night in the family’s home in Humboldt Park.

The boys had been playing in the home in the 1000 block of North Francisco Avenue around 9 p.m. when the 6-year-old saw the handgun atop a refrigerator, took it and fired it in the direction of his brother, Eian Santiago, hitting him in the head, police said.

Santiago, a manager at a Papa Ray’s Pizza restaurant, was at work and his girlfriend, the victim’s mother, was with her 1-year-old child getting milk from a store. Hector Salgado was at the home and heard the gunshot, authorities said.
