BENTON — A 38-year-old Marion man has been sentenced in federal court to 10 years in prison, after he earlier pleaded guilty to a crack cocaine conspiracy.

Tommy T. Langston, a/k/a “G,” was sentenced on an indictment charging conspiracy to distribute 28 grams or more of crack cocaine.

In addition to being sentenced to 120 months in federal prison, he was ordered to serve 8 years of supervised release, and fined $400.00.

The offense occurred between October 2014 and July 2015, in Williamson and Jackson Counties. Evidence at the plea and sentencing hearings established that Langston was involved with others in the distribution of crack cocaine in the Marion and Carbondale areas.

During the investigation, Langston sold crack cocaine to confidential sources working for law enforcement. At sentencing, the judge found that Langston was responsible for the distribution of 154.2 grams of crack cocaine.

Co-defendant Tammy R. Whitton has previously been sentenced to 120 months in prison for her role in the crack cocaine conspiracy.

Two co-defendants have pleaded guilty to their roles in the crack cocaine conspiracy and are awaiting sentencing. One co-defendant has pled not guilty and is awaiting trial.

The ongoing investigation is being conducted by the Southern Illinois Enforcement Group, Drug Enforcement Administration, Jackson County Sheriff’s Office, and Carbondale Police Department. The Williamson and Jackson County State’s Attorney’s Offices also assisted in the investigation.
