A Columbus man was sentenced Thursday to 135 months in prison for his role as a supplier in a large-scale drug-trafficking and money-laundering conspiracy.

Levi Winston, 50, of Columbus, pleaded guilty on May 2, 2013 to charges of conspiracy to possess and distribute more than 1,000 kilograms of marijuana and money laundering. Judge Frost sentenced Winston to 135 months on each count and ordered the sentences to run concurrently.

During the course of the investigation, a known drug trafficking organization transported several tons of marijuana from Mexico to central Ohio. Winston and his associates hid large quantities of the drugs inside tractor trailers and industrial machinery. On October 17, 2011, HSI special agents and task force conducted a controlled delivery of 1,798.12 pounds of marijuana to a warehouse that Winston had rented located in Gahanna, Ohio. Winston and several of his associates were later arrested on conspiracy to distribute illegal drug charges.

In addition to the nearly 2500 pounds of marijuana seized by investigators in Columbus, the cooperation of several individuals and intelligence gathered during the investigation of this conspiracy has directly led to the seizure of an additional 3500 pounds of marijuana worth more than $3 million dollars in several other jurisdictions across the United States.
