The daughter of a pastor is in critical condition after being accidentally shot in the back of the head at a church in Florida.

Pastor Tim Kelley announced on Grace Connection Church's Facebook page on Sunday that the prognosis for his daughter, 20-year-old Hannah Grace Kelley, was not good.

"Please pray the swelling to goes down in her brain," he wrote.

The Pinellas County Sheriff's Office told WTSP that church member Moises Zambrana, who works as a security guard, was in a closet showing two other men the safety features on his 9mm handgun. Although Zambrana had removed the clip, he had failed to remove the round in the chamber. The gun went off and fired through a wall, striking Hannah Kelley in the back of the head.

"There's a little concerned that, you know, it happened, but it was accidental," church member Tony Diehl said. "I mean, nobody was intended -- nobody came to shoot anybody. It just happened."

Authorities say that Zambrana has a permit for the weapon and did not break any laws. No charges have been filed.
