LOS ANGELES – A former security screener who helped smuggle drugs through Los Angeles International Airport has been sentenced to more than 6 1/2 years in federal prison.

Prosecutors say Naral Richardson was sentenced Monday for conspiracy.

In his March guilty plea, Richardson acknowledged that he arranged for couriers to carry more than150 pounds of marijuana, cocaine and methamphetamine through Transportation Security Administration checkpoints in suitcases.

Prosecutors say Richardson received as much as $1,000 for each trip.

He was fired by the TSA three years ago and is the last of seven defendants to be sentenced.

Three other former TSA screeners and three drug couriers previously received prison terms.
