Briane Grey, acting special agent in charge of the DEA in Los Angeles, said the scheme was particularly reprehensible because it took place at LAX.

“The defendants traded on their positions at one the world’s most crucial airport security checkpoints, used their special access for criminal ends, and compromised the safety and security of their fellow citizens for their own profit,” he said in a statement.

The indicted screeners are Naral Richardson, 30, and Joy White, 27, who were both fired by TSA last year; and John Whitfield, 23, and Capeline McKinney, 25, both currently employed as screeners. All four have been taken into custody, and face up to life in prison if convicted.
