EAST ST. LOUIS — Five southern Illinois residents, including a Mt. Vernon woman, have been indicted in a one-count superseding indictment, charging conspiracy to distribute 28 grams or more of crack cocaine.

32-year-old Keenon J. Farr, a/k/a “Keeno,” 30-year-old Roderick L. McClain, a/k/a “Big Bama,” and 35-year-old Jeffery L. Cain, a/k/a “Fatz,” all of Carbondale, along with 35-year-old Tommy T. Langston, a/k/a “G,” of Herrin, and 45-year-old Tammy R. Whitton, of Mt. Vernon, are charged with conspiracy to distribute 28 grams or more of crack cocaine.

The indictment alleges that the offense occurred between October 2014 and July 2015, in Williamson and Jackson Counties. Farr and McClain made their initial appearances in federal court in Benton on September 17, 2015.

They are currently being held without bond pending a September 22, 2015, detention hearing. Cain, Langston, and Whitton have previously made court appearances and are being held without bond pending a November 14, 2015, jury trial.

If convicted, the crack cocaine offense carries a penalty of a minimum of 5 years to a maximum of 40 years in federal prison, to be followed by 3 years’ supervised release, and a $5,000,000 fine.

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.

The case is assigned to Assistant United States Attorney Amanda A. Robertson for prosecution.
