PALATKA, Fla. (AP) --Sheriff's investigators say they're trying to determine how a 4-year-old boy had access to a gun he used to shoot his mother as she drove a pickup truck in north Florida.
The shooting happened Tuesday afternoon.
Putnam County Sheriff's spokesman Joseph Wells says 31-year-old Jamie Gilt of Jacksonville owns the gun.
A deputy saw her behaving frantically inside the truck, which was stopped partially in the road. The deputy then saw she'd been shot in the back.
Wells says Gilt told deputies her son had accidentally shot her. She was taken to a hospital, but her condition wasn't available Wednesday.
Gilt appears to manage a Facebook page called Jamie Gilt for Gun Sense. The page says it aims to "protect and expand" Second Amendment rights and features pro-gun memes and videos.
Wells says investigators haven't been able to interview her.
It is a misdemeanor under Florida law for someone to store or leave a loaded gun where a child has access.
The boy is with relatives. The Florida Department of Children and Families is also investigating.
