History of Illinois Prisons

The origins of the Illinois prison system date back to the 1800s. Here is a brief overview of the major historical developments:

  • 1827 – Illinois State Penitentiary opens in Alton. It was the first state prison built in Illinois.
  • 1833 – Stateville Correctional Center opens in Joliet. It is still one of the largest maximum security prisons in Illinois today.
  • 1858 – Joliet Correctional Center, originally known as Illinois State Penitentiary, opens. It was notorious for its poor conditions and abuse of prisoners.
  • 1860s – Cook County Jail opens in Chicago. It serves as the main jail for Cook County to this day.
  • 1920s – Illinois abolishes its convict lease system which had leased prisoners out to private companies as cheap labor.
  • 1930s – Stateville introduces several rehabilitation programs including education, vocational training, counseling, and religion.
  • 1960s – Several riots occur in Illinois prisons due to poor living conditions and overcrowding issues. Reforms were enacted.
  • 1970s – Illinois prison population grows rapidly leading to serious overcrowding issues again. More prisons are constructed.
  • 1980s-90s – “Tough on crime” policies lead to dramatic rise in Illinois incarceration rates. Medical care issues, gang violence, and staffing shortages plague prisons.
  • 2010s – Illinois prisons remain overcrowded. Solitary confinement practices draw criticism. Efforts begin to reduce prison population.

This history highlights the rapid growth of the Illinois prison system along with recurring issues such as overcrowding and poor living conditions. Rehabilitation and reform efforts have only sometimes succeeded in improving the system.

Controversies and Issues Facing Illinois Prisons

Illinois prisons contend with many systemic issues and controversies including:

Overcrowding

  • Almost all Illinois prisons hold more inmates than their design capacity, putting a strain on staff and infrastructure.
  • Overcrowding contributes to increased violence, rapid spread of illness, and poor access to programs for inmates.
  • Prison population exploded due to “tough on crime” policies from the 1980s-1990s.
  • Electronic monitoring, custody alternatives, sentence reductions and other reforms are aimed at reducing overcrowding.

Solitary Confinement

  • Illinois used prolonged solitary confinement practices that kept inmates in near total isolation for years.
  • Led to mental illness, suicides, self-harm among inmates in solitary units like Pontiac and Tamms.
  • Reforms have limited solitary to shorter periods and require mental health monitoring.

Staffing Shortages and Healthcare

  • Illinois prisons experience high staff vacancy rates for correctional officers and healthcare professionals.
  • Resulted in dangerous conditions where inmate needs went unmet. Some facilities were under temporary federal oversight.
  • Low salaries make hiring difficult. Current employees face high risks of burnout and trauma.

Violence and Inmate Deaths

  • Both inmate-on-inmate violence and use of force by staff has resulted in deadly outcomes.
  • Several prisons reported spikes in homicide and suicide rates in recent years.
  • Poor supervision, gang activity, overcrowding and availability of contraband weapons cited as factors.

Rehabilitation and Recidivism

  • Critics argue prison programs are underfunded and fail to adequately prepare inmates for release.
  • Budget cuts during Illinois’ financial crisis from 2015-2017 led to further program reductions.
  • Illinois’ recidivism rate of around 48% leaves room for improvement.

Addressing these systemic issues remains an urgent priority if Illinois hopes to run humane, rehabilitative and cost-effective prisons in the long run. Ongoing reforms seek to create lasting change.

Notable Inmates of Illinois Prisons

Illinois prisons have housed many notorious and famous inmates over the years. Here are a few high-profile examples:

  • John Wayne Gacy (Stateville Correctional Center) – The “Killer Clown” was one of the most infamous serial killers. He sexually assaulted, tortured and murdered 33 teenage boys and young men between 1972-1978. He was convicted in 1980 and executed by lethal injection in 1994.
  • Richard Speck (Stateville) – In 1966, Speck killed eight student nurses from South Chicago Community Hospital in a horrific mass murder. His natural life sentence spared him the death penalty. He died of a heart attack in prison in 1991.
  • Charles Manson (Stateville) – The cult leader of the Manson Family served time at Stateville in the 1960s for auto theft and skipped parole. He later orchestrated the 1969 murders of Sharon Tate and others in California.
  • Dennis Hastert (Rochester Correctional Center) – The former Speaker of the U.S. House of Representatives served time for illegally structuring bank transactions to pay hush money related to his sexual abuse of teenage boys years earlier. He was released in 2020.
