Loaded gun magazine with inscription discovered on flight
No additional items of concern were found, and the flight departed safely by 7:56 p.m. AP
A passenger boarding a Frontier Airlines flight in Atlanta made a startling discovery — a loaded gun magazine marked with mysterious initials — prompting a multi-agency investigation, authorities confirmed.
The incident occurred Sunday around 4:30 p.m. aboard an Airbus A320 parked at Hartsfield-Jackson Atlanta International Airport. According to the Atlanta Police Department, a traveler found the magazine containing ten hollow-point rounds near seat 7A while the aircraft was preparing for its return flight to Cincinnati. The magazine was reportedly engraved with the initials “K H.”
Police coordinated with the Transportation Security Administration (TSA), Department of Aviation, Department of Homeland Security, Frontier Airlines security, and Atlanta Police K-9 units to secure the area. All passengers were deplaned, the aircraft was thoroughly searched, and everyone on board was re-screened.

Authorities said no additional items of concern were found, and the flight was cleared for departure at 7:56 p.m. The FBI has been notified and is assisting with the ongoing investigation.
Frontier Airlines told Fox 5 Atlanta that the magazine and ammunition were later determined to belong to a law enforcement officer who had been aboard an earlier flight on the same aircraft.
“A subsequent investigation confirmed that the ammunition belonged to a law enforcement officer who was on an earlier flight on the same aircraft,” Frontier said in a statement. “The ammunition and magazine were taken into custody by the Atlanta Police Department, and the property owner was referred to Atlanta P.D. to retrieve his items.”
However, an Atlanta police source told the outlet that investigators have not yet independently verified that account.
“I’ve heard of a lot of delays and canceled flights, but I’ve never heard of this before. This is brand new,” passenger Terry Foster told reporters.
The investigation remains active as federal and local authorities work to confirm how the loaded magazine was left aboard the plane and whether any security protocols were breached.
