In Gainsville, Florida, a three-year old child who was home with two other children and an adult who was not his parent, took a loaded gun from an unlocked case and shot himself.  The child later died at the hospital. 

“Well, the case is still under investigation, but what we know at this point, it was likely an accidental occurrence,” a police sergeant said. “The fact that he got a hold of it obviously meant it was in an area that shouldn’t have been. However, you know, how it got there and why it was there was still being determined,” he added.
