According to a Riverside, Ohio police sergeant, “a 3-year-old got ahold of his father’s weapon and accidentally shot himself in the leg.”  The boy found the gun in a bedroom and brought it to the living room where he was playing with it when it went off.  The boy’s father was home at the time. 

Firearm safety is of the “utmost importance,” especially when children are in the home, the sergeant said. “If you’re going to own firearms, buy a safe. Secure them, keep them unloaded if you’re not going to put them in a safe. Your children are most important.”

Ohio does not mandate gun locks or gun safes.
