Thirteen members of a prison-based methamphetamine distribution ring have been convicted and sentenced following a multi-year federal investigation. Authorities say state inmates Edward Kelvin Pope, David Wilson, and Kevin Josue Campos Rivera coordinated drug trafficking operations from Central State Prison in Macon, working with federal inmate Jose Santos Isaola Cisneros at the Federal Correctional Institution in Atlanta to distribute methamphetamine through couriers and distributors across north Georgia. Pope, known as “Paw Paw,” was already serving a life sentence plus 70 years for armed robbery, kidnapping, and other violent crimes at the time of the offenses.
