ATLANTA (AP) — A former security worker has pleaded guilty in a plot to smuggle drugs through the Atlanta airport.

U.S. Attorney Sally Quillian Yates says the guilty plea was given by 26-year-old Timothy G. Gregory, a former Transportation Security Administration employee. Yates says Gregory tried to smuggle cocaine through security at Hartsfield-Jackson International Airport.

Yates says an undercover officer provided Gregory with five kilograms of fake cocaine and $5,000 in May. Gregory delivered the fake drugs through a TSA checkpoint to another undercover officer in the terminal.

Yates says Gregory agreed to transport another 10 kilograms of fake cocaine in August.

Gregory was indicted in August on three counts of drug trafficking.

Gregory faces a maximum of life in prison and fines up to $10,000,000. Gregory’s sentencing is scheduled for Dec. 18.
