Georgia Diagnostic and Classification State Prison

Georgia Diagnostic and Classification State Prison is a prison for adult male inmates located near Jackson, Georgia. It can house a maximum of 2,487 inmates. The mission of the facility is to ensure public safety and effectively house offenders while operating a safe and secure facility. 

This prison conducts diagnostic processing for male offenders, houses offenders assigned to the 90-Day (S.T.E.P -Segregated Transition Educated Program), house offenders Under Death Sentence (UDS), and carries out state ordered executions. It also houses a Special Management Unit (SMU), consisting of 192 beds.

The housing consists of eight cell blocks containing both double-bunked and single-bunked cells. There are also seven dormitories, 256 general population inmates, medical unit, and a 17-bed S.T.E.P (Segregated Transition Education Unit) for sex offenders who are close to being released. This facility also houses a C.E.R.T. Team, Tactical Squad, and a Fire Station.

This facility is the central hub where sentenced felons begin the process of being admitted into the Georgia State Correctional System. Numerous county jails are paid for by the state to house sentenced felons until space becomes available in the prison system. 

Sentenced felons may spend years in local jails until housing space becomes available in the state prison system. While at GDCP, inmates are either in the process of being classified and tested, or they are assigned as a "permanent." 

Inmates who are 'permanents' will serve their entire sentence at the GDCP, while the remainder of inmates will be tested and then moved to other prisons based on their classifications.

The Georgia Diagnostic and Classification State Prison is the largest prison in the state, and it holds the state execution chamber as well as Georgia’s death row for male inmates. 

The "Death House" is an isolated structure where state ordered executions are carried out. The "house" is a single-entrance fortified building, accessed only through the prison yard. Upon entry to the Death House, witnesses to executions are immediately put in an observation room, approximately 20' X 20', with three 16' long wooden benches to seat them. 

When seated, a glass window is seen directly in front of the first row of benches. An access door to the left of the viewing window leads to the execution room. Immediately to the right of the observation room (but still within it) is a storage area that houses the non-functional electric chair (nicknamed "Old Sparky") that was used before the implementation of lethal injection.

The 50th convicted killer executed in Georgia since 1973 was Roy Willard Blankenship on June 23, 2011; it was the first execution carried out using a new sedative, pentobarbital, replacing sodium thiopental. 

In March 2011, agents with the U.S. Drug Enforcement Administration seized Georgia's supply of sodium thiopental, which attorneys for several death row inmates said Georgia had improperly imported from a pharmacy operating out of the back of a driving school in England. Hospira Inc. of Illinois, the only U.S. company that manufactured sodium thiopental, said in January it would stop making the drug after Italy objected because the European Union has banned the export of drugs used for death penalty.
