From an article:
Investigators tell Channel 3 that upon their arrival they found a child suffering from a significant bullet wound to the back of the head.
It was reported to police that the juvenile was with a friend and the two were handling a loaded firearm when the friend pulled the trigger of a small caliber revolver and accidentally struck the victim in the back of the head.
Investigators say the child was conscious and talking to officers and was brought to the hospital by his mother and is currently being treated for the injury that is believed to be non-life threatening
Investigators did recover the weapon. The investigation is ongoing and more information will be released when available.The article doesn't say how the children got hold of the gun.
Every gun in the hands of a child must first pass through the hands of an adult.
