A South Carolina trooper says he found a kilogram of cocaine in a suspect's prosthetic leg, after he pulled over a vehicle for driving slow in the fast lane.

The Anderson Independent-Mail reports trooper Brad Davis testified at a preliminary hearing Friday that he felt an odd bulge when he patted down Glodualdo Moreno Lojan. Davis says a plastic bag was stuffed between Lojan's leg and his prosthesis.

Lojan and two others in the car face cocaine trafficking charges.

Davis says he pulled over the car with Texas plates in July for traveling 50 mph in the left lane on Interstate 85.

Lojan's attorney, Kurt Tavernier, says the car should not have been stopped, since 50 mph is over the minimum highway speed.

The three remain in jail without bond.
