2-year old Texas boy shoots and kills self with father's gun

A man and his 2-year old son were in the father's bedroom, in Corsicana, Texas, when his son found a loaded, unsecured handgun.  The boy discharged the gun, hitting himself in the head, and died soon after.

The father was in a walk-in closet only feet away.

From an article:

Kinsler Allen Davis was taken to Navarro Regional Hospital and then flown by helicopter to Children's Medical Center in Dallas, where doctors pronounced him dead just after 11 p.m. The boy was less than a month away from his third birthday.  

A preliminary investigation shows the boy found the handgun inside a bedroom and fired it. The bullet hit him in the head, Chief Bratton said. The boy's father was in a walk-in closet in the bedroom where the boy was, feet away from where the accident occured. Initially, the chief reported the father to be in another room but he later said that was incorrect. .... 

Bratton urged gun owners to take extra precautions to prevent accidents like this in the future.
"Even if you have a lot of experience with firearms you still need to take additional precautions to ensure this doesn't happen," he said. 

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