TAMPA, Fla. (AP) - A 3-year-old boy died after shooting himself with his uncle's gun in a Tampa apartment.
Hillsborough County Sheriff's officials say the boy's uncle, 29-year-old Jeffrey D. Walker, was arrested late Tuesday and charged with culpable negligence.
Sheriff's spokeswoman Debbie Carter says Jadarrius Speights found the unsecured 9 mm handgun in a backpack in a bedroom he shared with his uncle. The child's parents - Jasmine Bell and Trentin Speights - were in the bedroom with the child when the gun went off.
Officials say Walker purchased the gun at a gun shop in the Tampa area and has a concealed weapons permit.
Authorities say a 911 call came in at 7:10 p.m. The boy was taken to Florida Hospital Tampa, where he died.
