Martin, U.S. Attorney for the Middle District of Tennessee.The verdicts stem from the attempted delivery of nearly 900 pounds of marijuana to the defendants’ family farm in Sparta on March 28, 2007.Agents and officers with the Tennessee Bureau of Investigation (TBI) tracked the marijuana to the farm, where the defendants were arrested as they began to unload it.
