POPLAR BLUFF, Mo. (AP) — Authorities say a father has accidentally shot and wounded a southeast Missouri teen with a muzzleloaded gun.

The Daily American Republic reports that 17-year-old Kaitlyn Elise Pullam, of Poplar Bluff, was taken to St. Louis Children’s Hospital in critical condition after Monday’s shooting.

The girl’s mother told officers she had brought home two .50-caliber muzzleloaded guns from a cabin.

Butler County sheriff’s investigator Randle Huddleston said the girl’s father thought they were unloaded. He picked one of them up, and while handling the firearm, he inadvertently squeezed the trigger, and it went off.

Authorities say the bullet went through the wall of the girl’s bedroom. Butler County Sheriff’s Sgt. Brandon Lowe says the bullet went through the girl’s shoulder and that shrapnel hit her in the face and chest.
