A Southwest Airlines baggage handler has confessed to stealing five firearms from checked bags, according to a story from The Hill.

Mark Hunter, of St. Louis, was sentenced to six months in prison and three years of probation, the newspaper reported.

A Southwest Airlines passenger reported his pistol missing from his baggage. Federal agents compared the dates of other firearm thefts to Southwest’s employee  schedules.

“Records indicated that Hunter was working and had access to baggage from which other guns had been reported stolen,” the Department of Justice wrote.

Hunter was interrogated by federal employees and confessed to the theft of five firearms from the checked luggage he handled while working at the St. Louis airport.

An investigation into the thefts was conducted by the Manchester Police Department, the Bureau of Alcohol, Tobacco, Firearms and Explosives, the Department of Homeland Security and the Transportation Security Administration.
