— A woman was accidentally shot in the head on Saturday outside a gun show in Raleigh, according to authorities.

Wake County Sheriff Donnie Harrison said three people were inside a pickup truck around 10:15 a.m. outside the Dixie Gun and Knife Show at the N.C. State Fairgrounds when the shooting happened. The driver, identified as 30-year-old William Daniel Glosson, of Cameron, had just bought two guns from the show.

Glosson, who has a concealed-carry permit, handed one of the unloaded guns to Lasonya Judd, who was sitting in the back seat, and he also handed her a loaded gun he already had in the truck. As Judd was looking at the guns, she accidentally fired one, and the bullet struck Alyssa Lewis Glosson, 29, in the back of the head while she was sitting in the truck's passenger seat.

"He handed it to the lady in the backseat. He says, look at this, and somehow or another when she grabbed it, the gun went off, discharged," Harrison said. "It looked like it might have hit the seat rest, so that could have stopped some of the impact."

Alyssa Glosson, who is married to William Glosson, was talking with emergency personnel when she was put in the ambulance to be taken to WakeMed. Authorities said the bullet hit the seat before striking Alyssa Glosson.

In a 911 call, the William Glosson said the gun went off accidently and "grazed" his wife's head. He said she had a headache and neck pain, but he described her as conscious and breathing.

The shooting on Saturday is the second accidental shooting at the same gun show in the last three years. In 2013, a 12-gauge shotgun discharged while its owner removed it from its case at a security checkpoint at the entrance to the show, according to previous reports.

Two people were shot in the incident—one in the hand and the other in the right torso.

Harrison said hopefully a lesson can come from the incident.

"Don't be handling a loaded firearm unless you know what you're doing," he said.

The shooting closed the show for a day, but it was reopened the next. Glosson was treated and released.
