COLUMBIA, S.C. — A deputy working security at a gun show in South Carolina fatally shot a customer who fired on him on Saturday, November 14, authorities said. The shooting happened at the Jamil Temple event center in Columbia, where the South Carolina Arms Collectors Association was holding a gun and knife show.

The Lexington County deputy was wounded in the exchange and was taken into surgery, the Lexington County Sheriff's Office said in a statement. The sheriff's office said the deputy was in stable condition. The person who fired on the deputy was killed; officials have not released that person's name.

A heavy response at the Jamil Temple

A photograph released by the sheriff's office showed law-enforcement vehicles and yellow tape outside the Jamil Temple on Saturday as authorities responded to the shooting. Local reporting from the scene described a large law-enforcement response at the event center, at 206 Jamil Road in the Harbison area of Columbia, just off Interstate 26 near St. Andrews Road, and said the Columbia Police Department was assisting. The sheriff's statement carried by AP did not itself confirm those scene details.

What officials have not said

The sheriff's office did not release any additional information about the shooting in its statement — no time for the shooting, no name for the deputy or for the person killed, and no account of what happened in the moments before the customer opened fire. The Associated Press said the South Carolina Arms Collectors Association did not immediately respond to an email and a phone call seeking comment.

The show's own rules ban loaded weapons

According to the rules for the gun show posted on its website, loaded weapons are banned at the event except for on-duty police officers, and all weapons must have their actions secured. How a customer came to fire a weapon at a show run under those rules is one of the central questions the investigation will have to answer — officials have not yet addressed it.

The venue

The Jamil Temple is owned by the Shriners and is frequently rented out for public events, including gun shows, jewelry expos and roller derbies. On Saturday it was hosting the gun and knife show organised by the South Carolina Arms Collectors Association, a collectors' event where firearms and knives are displayed and traded under the show's posted safety rules.

What happens next

The sheriff's office is expected to release the identities of the deputy and the person killed, and a fuller account of the confrontation, as the investigation continues. The deputy remains in stable condition after surgery. Until officials publish those details, the confirmed record of this shooting is the short one above: a customer fired on a deputy working security, the deputy fired back, and one person is dead.
