A Milwaukee father faces charges of recklessly endangering safety after an incident where one of his sons shot the other. Prosecutors maintain it’s not the first time 27-year-old Joshua Walls put his children in harm’s way. Walls tells police he was holding the gun for a friend. His two-year-old son found the weapon behind a cable box and handed it to his four-year-old brother. The older boy accidentally fired the gun. Drugs were also found in the home. The victim required surgery for a wound to his foot.
