A U.S. District Court judge has sentenced a Charleston gang member to 33 years in prison without parole in the ambush-style killing of the gang’s leader.

U.S. Attorney Bill Nettles and 9th Circuit Solicitor Scarlett Wilson stated Tuesday that Cephus Mitchell, 21, was sentenced by Judge P. Michael Duffy based on his guilty plea to the following charges: The murder of Jamar Gathers, shot to death in the Bridgeview Apartment Complex on Aug. 21, 2010; use and discharge of a firearm in a driveby shooting; and participation in a drug conspiracy.

Court documents list Mitchell as part of a loosely organized criminal street gang known as B-Mob that sold drugs out of the Bridgeview Apartment Complex in Charleston. Gathers was considered the leader of the organization.
