A Fort Stewart soldier has been charged with cocaine trafficking as part of a drug investigation at the southeast Georgia Army post.

Pvt. 1st Class Mario Figueroa remained jailed Wednesday following his arrest last week. Liberty County sheriff's Maj. Jeff Hein said the arrest followed a three-month investigation by military and civilian authorities.

Fort Stewart officials said in a news release other soldiers were apprehended Tuesday on suspicion of drug crimes, but did not say how many or if they were being charged. Fort Stewart spokesman Kevin Larson declined to comment further.

Hein said investigators questioned the soldiers and several were cleared of wrongdoing.

It was not immediately known if Figueroa had an attorney. In Georgia, someone can be charged with cocaine trafficking for possessing 28 grams or more.
