Solitary Confinement

Brief written July 16, 2026 from GPS Intelligence System data.

Georgia’s prison system has long relied on solitary confinement as a tool of control, most notoriously in the Special Management Unit (SMU) at the Georgia Diagnostic and Classification State Prison (GDCP). A tiered system of restrictive housing—from Tier I to the SMU’s Tier III—has subjected thousands of incarcerated people to isolation so extreme that it has drawn a rare civil contempt ruling, a 93-page Department of Justice findings report, and comparisons to torture by United Nations experts. In the SMU, prisoners are confined in 54-square-foot cells for 22 to 24 hours a day, often for years, with devastating psychological consequences. Despite a 2019 federal settlement mandating reforms, a 2024 contempt order found GDC officials falsifying compliance records, placing people in strip cells, and stalling “with no desire or intention to comply.” This analysis draws on court records, DOJ findings, clinical research, GPS’s own investigative reports, and mortality data to map the architecture of isolation and its human cost.

The Architecture of Isolation: The SMU and Tier II/III Segregation

At the Georgia Diagnostic and Classification State Prison, the state operates its Tier III Special Management Unit—a six-cellblock facility where prisoners are confined to single-bunked cells the size of a parking space, each roughly 6 feet by 9 feet. Per GDC’s own policy (SOP 209.09, effective April 2025), the Tier III Program is a minimum 13-month incentive-based regimen for people who have committed violent, disruptive, or predatory acts. Yet the reality, documented in federal court and expert testimony, is a system of near-total sensory deprivation that can last for years. Dr. Craig Haney, a leading prison conditions expert, inspected the SMU in 2017 and described it as “one of the harshest and most draconian” solitary confinement facilities he had seen in decades, “as chaotic and out-of-control as any such unit I have seen in decades of conducting evaluations.”

Conditions inside the SMU, established in Gumm v. Ford litigation and a subsequent contempt order, include cells with no outside light—a small exterior window is covered by a shield—solid metal doors with only a narrow glass window, and a constant din of yelling and banging mixed with the permeating stench of feces, dampness, and mildew from in-cell showers. For the most restrictive cellblocks, prisoners were confined for 22 to 24 hours per day without books or personal property, and prohibited from leaving their cells for at least 90 days upon arrival. Meals passed through a slot in the door. As documented by the DOJ, chronic understaffing made outdoor exercise and programming impossible—systemwide correctional officer vacancy rates hovered around 50%, and exceeded 70% at the ten largest facilities.

At the time of the Haney inspection, the SMU held 182 men. A staggering 78% (141) had been in isolation for more than two years; 44% (80) for more than four years; and 26% (47) for more than five years. Named plaintiffs like Timothy Gumm, Johnny Mack Brown, and Robert Watkins endured 7.5, 9, and 8 to 10 years respectively inside the SMU. These durations brazenly exceed international norms and even the general 24-month cap that GDC accepted in the 2019 settlement—a cap it frequently ignored. GDC’s Tier II placement criteria at Hancock, Hays, Macon, Smith, Telfair, Valdosta, and Ware State Prisons cast a wide net, and the 90-day review cycles eclipse the United Nations Mandela Rules’ 15-day threshold for prolonged solitary confinement by an order of magnitude.

The Mental Health Toll: “Irreversible and Even Fatal Harm”

The psychological consequences of prolonged isolation are neither new nor contested. The U.S. Supreme Court recognized as early as 1890 that solitary could drive prisoners into a “semi-fatuous condition” or make them “violently insane.” Modern clinical research confirms damage that is severe and dose-dependent. A 2025 PLOS One meta-analysis of 171,300 inmates found that disciplinary confinement significantly elevated psychological distress, psychiatric symptoms—including self-harm, thought disorders, and obsessive-compulsive symptoms—and the need for hospitalization. Dr. Stuart Grassian identified a specific “SHU syndrome” marked by hypersensitivity to stimuli, perceptual distortions and hallucinations, panic attacks, cognitive impairment, paranoia, and impulse control problems. In severe cases, Grassian documented florid delirium, a confusional psychosis with intense agitation and fear.

In Georgia, the SMU became a reservoir of mental illness. Dr. Haney’s 2017 expert report found that 39% of SMU prisoners (70 of 180) carried a diagnosed mental illness, yet they remained locked away. Haney warned that conditions created “a significant risk of very serious psychological harm” and could produce “irreversible and even fatal harm.” He described encountering “a cell block full of inmates with serious mental illness; a man who had been locked for months inside a pitch-black cell; and another man, naked and psychotic, whose cell was covered in blood.”

Across the system, segregation concentrates suicide and self-harm. In the iconic Kaba et al. study of New York City jails, although only 7.3% of admissions included solitary confinement, these individuals accounted for 53.3% of all self-harm acts and were 6.9 times more likely to self-harm after controls. GPS’s mortality records, which have tracked 1,849 deaths in GDC custody since 2020, reveal a sequence of deaths inside Georgia’s isolation units. Miguel Angel Duran, 44, died by suicide in “the hole” at Central State Prison on March 1, 2026. Denecia Nichelle Randall, 28, hanged herself in lockdown at Pulaski State Prison on March 30, 2026. Justin Waymon Hollingsworth, 43, hanged himself in segregation at Rogers State Prison in June 2025. Calvin Earl Noble, 25, died in a one-man cell at Macon State Prison in August 2025. Stephen Prochaska died by suicide inside Augusta State Medical Prison—the state’s highest-level mental health facility—in January 2025. And Sheqweetta Vaughan, 32, a postpartum mother on psychotropic medication, was found decomposing in her 90-degree segregation cell at Lee Arrendale State Prison on July 9, 2025, more than 28 hours after she had called for medical help—a timeline inconsistent with required 30-minute welfare checks.

The observation cell paradox is well-documented: suicide watch cells disproportionately fill with prisoners transferred from segregation, cycling between isolation and crisis intervention. The DOJ found that queer and transgender prisoners were placed in solitary after reporting sexual assault or during mental health crises, turning isolation into a punitive response to vulnerability. The systemic backdrop magnifies these tragedies. Georgia ranks 48th nationally for adult mental health care access, 51st for adults unable to see a doctor due to cost, and 48th for mental health workforce availability. The state has not expanded Medicaid. GDC awarded Centurion Health a $2.4 billion, nine-year no-bid contract for medical and mental health services in 2024. A forensic competency backlog of over 500 people awaiting evaluation and more than 700 awaiting hospital beds pushes mentally ill defendants into the prison system by default. Crucially, GDC stopped publicly reporting cause-of-death data after February 2024, further obscuring the true toll.

Legal Battles: Gumm v. Ford, the DOJ Investigation, and a Contempt Finding

The modern legal fight over solitary in Georgia began with a handwritten complaint. In 2015, Timothy Gumm, serving a life sentence and confined in the SMU since a 2010 escape attempt, filed a pro se civil rights lawsuit. The Southern Center for Human Rights and Kilpatrick Townsend & Stockton LLP later joined as class counsel. Dr. Haney’s 2017 expert report laid bare the SMU’s inhumanity, leading to a landmark settlement in January 2019. The agreement required a general 24-month cap on SMU confinement, three hours of daily out-of-cell time plus outdoor recreation, mental health evaluations before and during placement, tablets in cells, access to programming and books, and a prohibition on housing mentally ill people at Level III or above in the SMU. The court found the relief “necessary to prevent violations of constitutional rights.”

Compliance was a fiction. In a 100-page order on April 19, 2024, Chief Judge Marc T. Treadwell held GDC in civil contempt, finding that officials had been “running a four-corner offense and had no desire or intention to comply with the Court’s injunction; they would stall until the injunction expired.” The court documented widespread non-compliance: 40% of individuals were held beyond the time permitted by a similar statute; 24% were held without sufficient evidence; officers placed arriving prisoners in “strip cells,” leaving them naked or near-naked for hours or days; one prisoner testified to a broken toilet filled with feces, no mattress, no clothing, and freezing temperatures—testimony the GDC attorney did not refute. Compliance documents were “not only insufficient but also unreliable”—falsified. The court imposed daily fines of $2,500 ($75,000 per month) for six months, appointed an independent monitor at GDC’s expense, and extended the settlement. Two years earlier, an incarcerated person died of dehydration in a restrictive-housing cell at Calhoun State Prison after staff shut off his water and locked the food flap; his body was found seven to eight hours later.

Simultaneously, the U.S. Department of Justice pursued a statewide investigation under the Civil Rights of Institutionalized Persons Act. Launched in 2016 focusing on sexual abuse, expanded in 2021 to encompass protection from violence, and further expanded in April 2024 to include restrictive housing and disciplinary practices, the investigation culminated in a 93-page findings report on October 1, 2024. The DOJ concluded that Georgia prisons violate the Eighth Amendment. Explicitly, the report found that “GDC fails to control violence even in its segregated housing units and exposes incarcerated persons to an unreasonable risk of harm due to its inappropriate use of segregated housing.” Assistant Attorney General Kristen Clarke stated that incarcerated people are “assaulted, stabbed, raped and killed or left to languish inside facilities that are woefully understaffed … maimed and tortured, relegated to an existence of fear, filth and not so benign neglect.” GDC disputed the findings, and Senators Jon Ossoff and Raphael Warnock demanded swift action. As of early 2025, no formal resolution had been reached, and the DOJ’s restrictive-housing-specific findings—the prong expanded in 2024—have not yet been released, leaving the full scope of federal scrutiny pending.

The constitutional landscape remains unsettled. The Eleventh Circuit, which covers Georgia, has no published opinion squarely holding prolonged solitary unconstitutional. However, in 2024 the Third Circuit held in Williams v. Secretary that “it was clearly established that someone with a known preexisting serious mental illness has a constitutional right not to be held in prolonged solitary confinement without penological justification,” and the Supreme Court denied certiorari. The Fourth Circuit held long-term death row solitary unconstitutional in Porter v. Clarke (2019), while the Fifth Circuit declared in Hope v. Harris that solitary does not violate the Eighth Amendment “no matter how long it is imposed.” The foundational 1995 case Madrid v. Gomez established that solitary confinement of the mentally ill is per se cruel and unusual punishment—a standard Georgia’s SMU violates daily.

International Standards and the Reform Chasm

The United Nations Nelson Mandela Rules, adopted in 2015, define solitary confinement as 22 or more hours per day without meaningful human contact and treat any isolation beyond 15 consecutive days as prolonged solitary confinement, which two successive UN Special Rapporteurs on Torture have declared amounts to torture. Georgia’s SMU, where people are held for years in lightless cells with negligible human contact, stands in stark violation.

Other U.S. states have moved toward compliance. New York’s HALT Solitary Confinement Act limits solitary to 15 consecutive days and bans it for people under 21, over 55, pregnant, or with serious mental illness, mandating four hours of daily out-of-cell programming. Connecticut and Nevada set 15-day maximums; Massachusetts, Virginia, and New Jersey enacted comprehensive reforms with strict caps. Colorado, Delaware, North Dakota, and Vermont have eliminated restrictive housing entirely. California’s Ashker settlement ended indeterminate solitary at Pelican Bay and capped stays at five years. Data show these reforms can achieve dramatic reductions without a surge in violence: North Dakota achieved a 74% reduction in solitary, Oregon between 55.7% and 73.9%.

Georgia, however, has doubled down on punitive isolation. In late 2025, the state announced a $1.6 billion investment to build new prison walls and isolation beds, a “hardened” management model. In the same period, California invested $239 million to pilot the “California Model” at Valley State Prison and San Quentin, a rehabilitation-first approach centered on programming and step-down. International norms further highlight the gap: the United Kingdom’s independent prison inspectorate conducts regular inspections, and Germany’s prison law mandates resocialization as the singular goal of incarceration.

Transparency Failures and the Data Black Hole

Accountability is stymied by a near-total lack of public data. GDC does not disclose restrictive-housing population counts by tier and facility, nor suicide and self-harm incidents by tier, nor mental health classification breakdowns of the isolation population. The agency’s internal Friday Reports—which contain classification data—are not published. There is no public per-bed cost for the SMU or Tier II programs. GDC stopped reporting cause-of-death statistics after February 2024, making it impossible for analysts to accurately track homicides and suicides. The DOJ’s 2024 findings confirmed that GDC “inaccurately reports these deaths both internally and externally, and in a manner that underreports the extent of violence and homicide.” No public audit of GDC’s compliance with National Commission on Correctional Health Care standards exists, and other data gaps—such as no disaggregated pre-trial mentally ill defendant data—obscure the full scope of harm.

Ongoing Harm: What GPS Records Show

GPS’s intelligence system, which aggregates anonymized reports from incarcerated people and their families, documents a sustained pattern of rights violations and unattended mental health crises tied to solitary confinement. Over the past 12 months, 35 separate sources across eight facilities—including the GDCP SMU, Johnson State Prison, Calhoun State Prison, and Baldwin State Prison—reported due-process violations in restrictive housing placements, many rated as critical or high severity. Concurrently, 11 sources across three facilities reported mental health crises going unattended, with the GDCP SMU, Johnson State Prison, and Augusta State Medical Prison most frequently cited. These signals, alongside the contempt findings and the DOJ investigation, indicate that the systemic failures are not historical artifacts but present, ongoing realities for people trapped in Georgia’s isolation units.
