Hours after gun-rights advocate Jamie Gilt bragged on Facebook that her 4-year-old son “gets jacked up to target shoot,” the same child accidentally turned his mother into a target, shooting her in the back.

The 31-year-old Jacksonville woman was driving down a road in Putnam County, Fla., on Tuesday when her son managed to get hold of a gun while he was sitting in the back seat of the vehicle, according to a statement released by the Putnam County Sheriff’s Department.

Officials told the Florida Times-Union that the child fired a .45-caliber handgun that he found on the truck’s floor into the driver’s seat.

“She was shot through the seat and the round went through her back,” Sheriff’s Capt. Joseph Wells told the Times-Union. “There was a booster seat in the back of the vehicle, but, however, the boy was not strapped in when the deputy got to them.”
