4-year-old shoots self while playing with gun

A 4-year-old Dayton, Ohio boy found an unlocked, loaded gun and unintentionally shot himself in the leg.

From an article:

The grandfather was in charge of watching the boy.  He was cited on a charge of child endangerment.

Children Services was called to the home and took custody of a second child in the home.

Police said the child was removed because of the lack of supervision, but also because of the deplorable conditions found in the home.
