2 year old Pennsylvania toddler kills 11 year old sister

A 2 year old toddler has killed his sister with a gun left unsecured in a home. From an article:

Jamara Stevens, 11, was shot and killed in Philadelphia over the weekend by her 2-year-old brother.

Police say the gun was left in the house by their mother’s boyfriend, and on Saturday morning, one of the three Stevens’ children discovered the .357-caliber handgun on top of the refrigerator and brought it upstairs.

The toddler found it, pointed the loaded and cocked gun at Jamara and fired the weapon.

Every gun in the hands of a child must first pass through the hands of an adult.
