Distinguishing Feature: The Arizona State Prison Complex, Florence, is one of Arizona’s largest prisons and it houses some of the state’s most dangerous criminals.  The state’s death chamber is located at the Arizona.  

The Arizona State Prison Complex Florence, sometimes referred to as the Florence State Prison, though the actual Florence State Prison building has been closed, is one of the largest prisons in the Arizona Department of Corrections public prison system.  The state of Arizona also has inmates in privately operated prisons.  

Six Housing Units:

Central Unit - level 5 security
East Unit - level 3 security North Unit - level 2 security
South Unit - level 3 security
CB-Kasson - level 5 security
Globe - level 2 security
Tempe St. Lukes - level 2-5 security

The inmate population at the Arizona State Prison Complex Florence is tremendously varied.  They range from level 2 to level 5 security risks.  Level 2 offenders are considered low risk and area given a wide variety of opportunities for prison programming, including the opportunity to work off-site.  Level 5 offenders are considered high risk. In addition, death row and the state’s death chamber are located at this facility. 

The living conditions at the Arizona State Prison Complex in Florence vary from unit to unit.  However, prison understaffing has led to dangerous conditions for the guards and the inmates.  There is currently a lawsuit by guards pending against the state of Arizona, alleging that understaffing led to the conditions that permitted inmates to assault and seriously injure these guards.  Amnesty International has also criticized the living conditions at the prisons, due to overcrowding and extended periods in solitary confinement.

Because Arizona State Prison Complex Florence is actually divided into a number of different living units, not all of the inmates at the prison are eligible for all of the rehabilitation or other programs offered in the prison.  Therefore, it is important to look at prison programming by unit.  In the Central Unit, inmates are able to participate in prison work programs and the ABE and GED education programs.  In the Kasson Unit, inmates can participate in ABE and GED education programs.  They can also participate in special education programs, mandatory literacy programs, media programs, Title One, design for living, and alcohol education programs.  In the East Unit, inmates are prepared for reentry into society with cognitive restructuring classes, domestic violence classes, re-entry classes, parenting classes, and back to basics classes.  They can also participate in a poetry workshop.  In the North Unit, inmates can participate in ABE, GED, and ICVC programs.  They can also work in the prison and on outside work crews.  In the South Unit, inmates can participate in ABE and GED educational programs.  Vocational training includes a classic car restoration program.  They can also participate in two workshops sponsored by Arizona State University: Fiction Workshop and The Structure of Language.  These inmates have the greatest work opportunities at Florence, and can participate in construction technology, welding technology, wood and metal refurbishing, and metal fabrication programs.  They also have access to treatment programs including: re-entry curriculum, cognitive-thinking for a change, cultural diversity, conflict resolution, domestic violence, AA, back to basics, and S.M.A.R.T.  At the Globe Unit, inmate education programs include: mandatory education, GED, Chapter 1 literacy, college distance learning, parenting classes, and distance learning.  These inmates may also be on outside work crews and work with a variety of local government entities including the Arizona State Land Fire Crew. 

There are a number of prisoner work opportunities and the prisoners work on local work crews, work in a machine-shop, restore vehicles, fabricate metal, and refurbish wood and metal. 

The prison was originally constructed in 1908 by prisoners who lived in tents while they were building the prison.  This prison contained the state’s death chamber, which was originally a hanging scaffold.  This was replaced by a gas chamber after an unsuccessful hanging.   

Placidio Silvas, one of the suspects in the famous series of murders known as the Ruby Murders, and one of the subjects of the largest manhunt in United States history was incarcerated at Florence and scheduled for execution, but he escaped.
