Solitary Confinement

Brief written June 7, 2026 from GPS Intelligence System data.

The Architecture of Isolation: Georgia’s SMU and Tier II System

The United Nations Nelson Mandela Rules define solitary confinement as 22 or more hours per day without meaningful human contact, and declare that any period exceeding 15 consecutive days constitutes torture. Georgia’s Special Management Unit (SMU) at the Georgia Diagnostic and Classification State Prison (GDCP) has long operated in flagrant defiance of this standard. A comprehensive review by the nonprofit Georgia Prisoners' Speak (GPS) found that in the most restrictive cellblocks of the SMU, prisoners were confined for 22 to 24 hours a day in windowless 6-by-9-foot cells, with meals passed through a slot in the steel door. A small exterior window was covered by a shield, and the unit was perpetually saturated with the stench of feces and mildew. As of July 2017, 78% of the unit’s 182 residents—141 individuals—had been held in isolation for more than two years; 44% had exceeded four years, and 26% had spent more than five years in these conditions. The class-action lawsuit Gumm v. Jacobs (later Gumm v. Ford) documented that some prisoners were released directly from the SMU to the community at the expiration of their sentences, with no transitional programming.

This is not a relic of the past. GPS reporting describes conditions today that track closely with those documented a decade ago. Timothy Gumm, the lead plaintiff, was held in the SMU for 7.5 years despite 14 separate recommendations over four years that he be transferred out. Johnny Mack Brown endured nine years in the unit, and Robert Watkins served between eight and ten. The SMU’s stated mission—to “rehabilitate close security offenders back into general population prisons through structure, programming, incentives, and education”—is belied by the reality on the ground. Dr. Craig Haney, a leading national expert on solitary confinement, inspected the SMU in 2017 and described it as “one of the harshest and most draconian” units he had ever seen “in decades of conducting evaluations.” He found prisoners who were “among the most psychologically traumatized persons” he had ever assessed in that context, and warned that the psychological harm inflicted on some inmates “may be irreversible and even fatal.”

Georgia’s Tier II facilities—Hancock, Hays, Macon, Smith, Telfair, Valdosta, and Ware State Prisons—extend the isolation regime across the state. Their placement criteria include being a leader in a major disturbance, possession of a firearm or explosive device, or simply having multiple disciplinary infractions for assaultive behavior. GDC’s own fact sheet defines Tier II as a program where offenders “must have at least one” of a list of markers that can include an escape involving violence, participation in a riot, or being deemed a threat to facility safety. The reality on the ground is often more banal: GPS has documented reports that gang labeling can “stick” even after formal debriefing, amplifying the risk and duration of solitary confinement for those affected.

A 100-Page Contempt: The Gumm v. Ford Litigation

The most sustained legal challenge to Georgia’s solitary confinement regime began with a handwritten pro se complaint filed by Timothy Gumm in February 2015, after he had spent five years in the SMU following a failed escape attempt. The Southern Center for Human Rights (SCHR) and Kilpatrick Townsend & Stockton LLP later took up the case, and in January 2019 the parties entered into a sweeping settlement agreement. Its terms required a minimum of three hours per day of out-of-cell time in common areas, plus one hour of outdoor recreation; computer-based education; tablets in cells; mental health evaluations; food consistent with general population standards; a general 24-month cap on SMU confinement; and committee review of transfer readiness six to twelve months before release. The agreement also mandated $425,000 in attorney’s fees.

GDC never fulfilled its obligations. In April 2024, Chief Judge Marc T. Treadwell of the U.S. District Court for the Middle District of Georgia issued a 100-page contempt order detailing “flagrant” violations. The court found that GDC officials had falsified compliance documents, describing them as “not only insufficient but also unreliable.” Prisoners testified in the proceedings that they were denied showers, out-of-cell time, programming, cell clean-outs, and access to kiosks and book carts. One prisoner described a cell where the toilet was broken and filled with feces and urine from prior occupants; he was forced to urinate in a cup and pour it in the sink, or defecate on toilet paper and dispose of it on his food tray, with no mattress, no clothing, and freezing temperatures. The GDC attorney did not refute this testimony.

Judge Treadwell’s order further documented that GDC placed individuals in “strip cells” upon arrival at the SMU, taking their clothing and leaving them naked or near-naked for hours or days. The court concluded that GDC was “running a four-corner offense” with no intention of complying. It imposed $2,500 in daily fines (totaling $75,000 per month for six months), extended the settlement agreement, appointed an independent monitor at GDC’s expense, and ordered the agency to pay the plaintiffs’ enforcement costs. Extremely low staffing levels at the SMU had made even outdoor exercise impossible except when tactical officers were temporarily present.

This was not the first contempt finding. A prior ruling in April 2024 had already found that 40% of individuals held in solitary under New York’s HALT Act (a model law often cited for comparison) would have been held longer than permitted, and 24% were held without sufficient evidence. The Gumm settlement was originally designed to prevent exactly these constitutional violations—the court had found in 2019 that the prospective relief was “necessary to prevent violations of the inmates’ constitutional rights.” The gap between the settlement’s text and its implementation is a window into the systemic dysfunction of GDC oversight.

Mental Illness, Self-Harm, and the Suicide Pipeline

The deadly intersection of solitary confinement and mental illness is starkly documented in GPS’s research. As of 2017, 39% of SMU residents had a diagnosed mental illness. Dr. Haney testified that 70 of the 180 inmates then held there were designated mentally ill, and that it was “dangerous” to house them in such conditions. The academic literature, summarized in a 2025 meta-analysis of 171,300 inmates published in PLOS One, demonstrates significantly greater psychological distress, more psychiatric symptoms, and greater need for mental health services among those held in disciplinary confinement. In New York City’s jail system, researchers found that though only 7.3% of admissions included any solitary confinement, those individuals accounted for 53.3% of all acts of self-harm and 45% of potentially fatal self-harm. After controlling for other factors, people in solitary were 6.9 times more likely to self-harm. A separate study of 5,038 adolescent incarcerations found that a ban on solitary reduced self-harm gestures from 4.2% to 3.4%.

The consequences are lethal. GPS has independently tracked 1,816 deaths in GDC custody since 2020, many occurring in isolation cells. In July 2025, Sheqweetta Vaughan, a 32-year-old postpartum mother with documented postpartum depression on psychotropic medication, was found decomposing in segregation cell H-19 at Lee Arrendale State Prison. The cell temperature was in the 90s Fahrenheit. A neighboring prisoner reported hearing Vaughan call for medical help around 6 a.m. on July 8—more than 28 hours before her body was discovered. The pathologist stated decomposition was inconsistent with required 30-minute welfare checks. The GBI could not determine the cause or manner of death. In March 2026, Denecia Nichelle Randall, 28, died by suicide by hanging at Pulaski State Prison while in lockdown. Miguel Angel Duran, 44, died by suicide in segregation at Central State Prison that same month. Calvin Earl Noble, 25, died by suicide in a one-man cell at Macon State Prison in August 2025. Justin Waymon Hollingsworth, 43, died by suicide in segregation at Rogers State Prison in June 2025. Stephen Prochaska died by suicide at Augusta State Medical Prison—the system’s Level IV/V mental health facility—in January 2025.

Half of all prison suicides occur among the 6 to 8 percent of the population held in solitary confinement. The pattern is so established that it has generated an “observation cell paradox”: suicide watch cells are disproportionately filled with prisoners transferred from segregation units, cycling between isolation and crisis intervention rather than receiving sustained mental health care. The corrections industry has long documented that housing individuals in shower stalls dramatically increases suicide risk. At Smith State Prison, an inmate was held in a 3.75-by-6.75-foot shower stall with no mattress, toilet, ventilation, heat, or water for nearly three days; he ultimately hanged himself.

Despite this, GDC has not publicly disclosed suicide and self-harm data by tier and facility. The agency stopped publishing cause-of-death data after February 2024, making independent verification nearly impossible. The mental health classification system (Mental Health Levels I–V) is an administrative caseload count, not a clinical prevalence estimate. Centurion Health, the private corporation that has held the state’s mental health contract since 1997 (and was awarded a $2.4 billion, nine-year, no-bid consolidated medical contract in 2024), has its own performance metrics hidden from public view. The state ranks 48th in the nation for adult access to mental health care, 51st for the share of adults with mental distress unable to see a doctor due to cost, and 48th for the share of adults with substance use disorder not receiving treatment.

Violence, Staffing Collapse, and the DOJ Findings

The U.S. Department of Justice launched a statewide civil investigation of Georgia’s prisons in September 2021 under the Civil Rights of Institutionalized Persons Act (CRIPA), after earlier investigations focused on LGBTI sexual abuse. The October 2024 findings report—93 pages long—declared that conditions in Georgia prisons violate the Eighth Amendment’s prohibition on cruel and unusual punishment. The report documented that GDC “fails to protect incarcerated people from violence and harm by other incarcerated people” and “from harm caused by sexual violence,” and that it “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.”

The scale of dysfunction is staggering. From January 2022 to April 2023, more than 1,400 violent incidents were recorded across 24 close- and medium-security prisons; 19.7% involved a weapon, 45.1% resulted in serious injury, and 30.5% required offsite medical treatment. Over the six-year period 2018–2023, GDC reported 142 homicides—48 in the first three years and 94 in the latter three years, a 95.8% increase. The 2019 prison homicide rate for Georgia was 34 per 100,000, nearly triple the national state-prison rate of 12 per 100,000. By 2025, the pace had accelerated: GPS reporting shows homicide investigations outpacing the prior year’s record, with June 2025 identified as the deadliest month on record.

The DOJ found that GDC’s staffing vacancy rate systemwide was approximately 50%, with rates exceeding 70% at the ten largest facilities. Without sufficient officers, even basic escorts to medical care became impossible, and victims “bled out from treatable stab wounds, waiting for a guard escort.” Vulnerable prisoners were forced to sleep in hallways, shower stalls, or outside after others took their assigned beds. Queer and transgender prisoners reported being placed in solitary after reporting sexual assault—a punitive response to victimization. An LGBTI-identifying person at Hancock State Prison was beaten and stabbed to death by gang members on May 22, 2022, after repeatedly asking to be moved because their life was in danger. A bystander who tried to apply pressure to the victim’s wounds was transferred to another prison the next day for protective custody.

Assistant Attorney General for Civil Rights Kristen Clarke described the findings in stark terms: “People are assaulted, stabbed, raped and killed or left to languish inside facilities that are woefully understaffed. Inmates are maimed and tortured, relegated to an existence of fear, filth and not so benign neglect.” GDC Commissioner Tyrone Oliver disputed the findings, claiming the DOJ “fundamentally misunderstands current challenges of operating any prison system.” U.S. Senators Jon Ossoff and Raphael Warnock demanded swift action. As of February 2025, DOJ and Georgia had not reached a formal resolution, and the DOJ Civil Rights Division has since been largely dismantled, leaving federal enforcement uncertain.

The violence is fueled by a torrent of contraband. GPS research has documented over 1,015 GDC staff and civilians investigated or arrested for introducing contraband since July 2010. The Atlanta Journal-Constitution documented more than 425 GDC employees arrested for crimes on the job between 2018 and mid-2023, the majority for contraband smuggling. Federal operations like Ghost Guard (2016, 46 indicted officers), Ghost Busted (2023, 76 defendants), and Skyhawk (2024, 150 arrests including eight GDC employees) have repeatedly exposed networks in which guards earned $500–$1,000 per smuggled cell phone and facilitated large-scale methamphetamine and fentanyl trafficking from inside prison cells. Synthetic cannabinoids, undetectable by standard drug tests, cause at least 13 deaths in Georgia prisons, with a single paper-soaked square selling for up to $400. The DOJ’s 2024 report noted a “steady stream of contraband cellphone videos and photographs appearing to show assaults, incarcerated people with injuries, weapons, and incarcerated people who seem to be under the influence of illicit drugs—all while inside Georgia prisons.” The result is a lethal mix: at least 49 drug overdose deaths occurred in Georgia prisons between 2019 and 2022, up from two in 2018, with methamphetamine identified as the leading cause. In at least 44 cases, GDC classified deaths as “natural” or “undetermined” when medical examiners later ruled them accidental overdoses—mirroring the broader pattern of underreporting the DOJ identified.

Data Blackout and the Unseen Crisis

Understanding the full scope of Georgia’s solitary confinement system is made deliberately difficult. GDC does not publicly publish current restrictive-housing population counts by tier and facility. There is no Georgia-specific per-bed cost data for restrictive housing—GDC’s annual budget submissions do not line-item the SMU or Tier II programs. The agency has not produced—to the DOJ or in response to legislative inquiry—facility-by-facility mental health classification data on a regular cadence. Suicide and self-harm incidents by placement type are not disclosed. Length-of-stay distributions for restrictive housing are unavailable. Drug seizure totals by facility and year are not aggregated publicly; naloxone administration data does not exist; prescription drug diversion inside prisons is not documented.

The state’s classification system understates true clinical need. The roughly 1,200 individuals classified as having “poorly controlled” mental illness and the 45 in “active crisis” represent only the most acutely identified subset; as the DOJ findings make clear, psychiatric staff are not consistently present across facilities. The GDC’s mental health unit inventory has been reconstructed by GPS from facility fact sheets, DOJ findings, and AJC reporting, because the department itself has not published a comprehensive version. There is no public audit of GDC’s compliance with the standards of the National Commission on Correctional Health Care, no published recidivism data isolating the seriously mentally ill, and no disaggregated dataset on pre-trial mentally ill defendants in county jails awaiting GDC transfer. The state’s refusal to expand Medicaid means most released individuals with mental illness are uninsured, with no continuity of care.

Aggregate Signals: Patterns Across Georgia Facilities

GPS’s internal intelligence system, which aggregates anonymized reports from incarcerated individuals, family members, and legal sources, shows persistent patterns that track the documented systemic failures. Over the past twelve months, GPS records show 27 reports of due-process violations in solitary-confinement placements across six facilities—led by Johnson State Prison, Augusta State Medical Prison, and GDCP—at severity levels ranging from high to critical, with 11 cases advancing to formal external complaints to entities including the Eleventh Circuit Court of Appeals and the DOJ Civil Rights Division. Additionally, GPS records show 8 reports of unattended mental health crises in solitary confinement at two facilities, all at critical or high severity, concentrated at GDCP and Johnson State Prison in the most recent six-month window.

These signals are not outliers; they are the granular reflections of the structural collapse the DOJ described, where disciplinary hearings lack due process, mental health emergencies go unaddressed for hours or days, and the only recourse for families is to elevate complaints to external oversight bodies already stretched beyond capacity.

The Longer Arc: From In re Medley to the Mandela Rules

The recognition that prolonged solitary confinement causes severe psychological harm is not new. In 1890, the U.S. Supreme Court in In re Medley observed that prisoners held in isolation fell into a “semi-fatuous condition,” became “violently insane,” or committed suicide. More than a century later, the Supreme Court has yet to definitively rule on the constitutionality of long-term solitary confinement for the non-mentally-ill. Justice Kennedy, concurring in Davis v. Ayala (2015), noted that “years on end of near-total isolation exact a terrible price” and suggested that “the judiciary may be required… to determine whether workable alternative systems for long-term confinement exist.” Justice Sotomayor, concurring in the denial of certiorari in Apodaca v. Raemisch (2018), wrote that such conditions come “perilously close to a penal tomb.”

The doctrinal foundation for protecting the mentally ill from solitary was laid in Madrid v. Gomez (1995), where a federal district court in California held that placing seriously mentally ill prisoners in the Pelican Bay SHU was unconstitutional, likening it to “the mental equivalent of putting an asthmatic in a place with little air to breathe.” The Third Circuit in Williams v. Secretary Pennsylvania DOC (2024) held that it is “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.” The Fourth Circuit in Porter v. Clarke (2019) became the first federal appellate court to hold that prolonged solitary confinement on death row violates the Eighth Amendment. The Eleventh Circuit, which governs Georgia, has not issued a published opinion squarely holding prolonged solitary unconstitutional—leaving the question open and the state’s practices in a constitutional gray zone.

International standards are unequivocal. The Mandela Rules, adopted by the UN General Assembly in 2015, prohibit indefinite solitary confinement and classify any period exceeding 15 consecutive days as torture or cruel, inhuman, or degrading treatment. UN Special Rapporteurs on Torture have repeatedly stated that prolonged solitary confinement amounts to psychological torture. Several U.S. states have enacted reforms: New York’s HALT Act caps solitary at 15 consecutive days and bans the practice for vulnerable populations; Connecticut and Nevada have adopted 15-day maximums; Colorado, Delaware, North Dakota, and Vermont have functionally eliminated restrictive housing. The American Psychiatric Association, the American Public Health Association, and the National Commission on Correctional Health Care all oppose prolonged solitary confinement of the seriously mentally ill. Georgia has enacted none of these protections.

Georgia’s historical arc offers a sobering precedent. In 1972, African American prisoners at Georgia State Prison (GSP) in Reidsville filed Guthrie v. Evans, a class-action lawsuit that led to 13 years of federal court oversight—the most comprehensive set of remedial decrees ever imposed on a single U.S. prison facility. Judge Anthony Alaimo’s orders addressed racial segregation, overcrowding, disciplinary due process, medical and mental health care, and virtually every aspect of prison operations. Yet when the Prison Litigation Reform Act of 1996 enabled termination of consent decrees, the apparatus of reform was dismantled. GSP itself was closed in 2022, and the state’s homicide rate behind bars has since risen from 8 in 2017 to 38 in 2023. The Gumm litigation now occupies the same institutional space, with its settlement enforced by a court that has already documented falsified records and systematic non-compliance. The reforms of one era become the unfulfilled mandates of the next.

The state has signaled its preferred response. In October 2025, Governor Brian Kemp announced a $1.6 billion investment in new prison construction and expanded isolation units—a hardened approach that prioritizes walls over staffing, programming, or mental health care. Georgia’s annual corrections budget already exceeds $1.62 billion, and yet the DOJ found systemic underfunding of core functions and a vacancy rate that makes safe operations impossible. The trauma endured by the nearly 50,000 people in GDC custody—and the thousands more cycled through solitary confinement each year—is both the predictable consequence and the intended product of a system that has chosen punishment over protection.
