4-year old Florida boy finds loaded gun and shoots self in head

A 4-year old boy was at his Orlando, Florida home with two others (an adult and a juvenile aung) when he found a loaded, unsecured gun.  He then discharged the gun, hitting himself in the head.

He is in critical condition.

From an article and video:

The child was shot around 9:30 a.m. at the Los Roble Condos off Silver Star Road.  

The child was taken to Arnold Palmer Hospital and was listed in critical but stable condition. 

A 911 caller reported the shooting, and Fire Rescue personnel began "rescue efforts," according to the Orange County Sheriff's Office. 

Deputies said two others, including an aunt, were in the home at the time of the shooting.  The boy's mother, however, was at work, deputies said. 

The Department of Children and Families is now involved in the investigation. 

It's not yet known how the shooting unfolded, and an investigation is ongoing.

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