Local and federal agents worked for three months to arrest two men who they say trafficked large quantities of marijuana from Atlanta.

The investigation by West Alabama Narcotics Task Force and the Federal Bureau of Alcohol, Tobacco, Firearms and Explosives ended with two arrests and the recovery of 15 pounds of suspected marijuana on Tuesday, said Lt. Teena Richardson, Tuscaloosa Police spokeswoman.

Gordon Jamal Shannon, 31, of Ellenwood, Georgia, and Jeffery Lee Warren, 30, of Atlanta, were both charged with trafficking marijuana.

They were being held at the Tuscaloosa County Jail with bond set at $1.5 million each.

Shannon and Warren were driving in separate cars on Interstate 20/59 on Tuesdsay when agents tried to stop them. Shannon, driving a Hyundai Elantra, attempted to flee but was eventually stopped in Tuscaloosa County, Richardson said.

Warren, who was following Gordon in a Dodge Challenger, exited the interstate but also was stopped by an officer.

The suspected marijuana was recovered from the Hyundai that Shannon was driving, Richardson said.

Officers smelled raw marijuana as they approached the vehicle and summoned a drug dog that alerted on the vehicle. Agents recovered 15 pounds of suspected high-grade marijuana valued at $52,500 from the back seat, Richardson said.
