Caldwell, Antoine Galen

Tenure Summary

Antoine Galen Caldwell’s career with the Georgia Department of Corrections began in 2000 as a sergeant at Dooly State Prison, where he rose through lieutenant, chief of security, and deputy warden of security by 2005. After a stint in audits and compliance, he returned to facilities as warden at Wilcox State Prison (2013, 2016), then moved to Johnson State Prison as warden from 2017 through 2021. He was promoted to warden of Georgia Diagnostic and Classification State Prison in January 2022, serving until the end of June 2023, when he took an assistant regional director role. Caldwell later became North Regional Director and, in 2026, Deputy Director for Field Operations.

During Caldwell’s tenures as the facility-lead warden at two prisons—Johnson and Georgia Diagnostic—GPS records attribute a total of 61 deaths to those facilities: 27 at Johnson and 34 at Georgia Diagnostic. An Atlanta Journal-Constitution investigation documented multiple homicides inside both prisons during his watch. A 2021 beating death at Johnson led to a $4 million settlement paid by the state in 2026, while a pending federal civil rights lawsuit names Caldwell directly. Broader systemic failures—severe overcrowding, staff shortages, contraband, and gang violence—were reported by the AJC and a Department of Justice investigation overlapping his leadership periods.

What happened on their watch

Wilcox State Prison (2013, 2016)
GPS records show no deaths attributed to Caldwell’s two separate wardenships at Wilcox. No lawsuits or intel reports from those years are tied to him.

Johnson State Prison (2017–2021)
Caldwell served as warden throughout this five-year period, during which the prison recorded 27 deaths. Per GPS records, those who died included Richard Forrest (36), Horace Kittles (73), Charles Bryson (60), and Tommy Henderson (35). According to an AJC investigation, at least two were homicides: Jerry L. Brown, 61, died of stab wounds and blunt-force injury to the face in November 2020, and David Lamar Henegar, 44, was killed by manual strangulation and blunt-force trauma to the head on October 16, 2021. Three lawsuits were filed in 2020 while Caldwell was warden—Carey v. The Georgia Department of Corrections, Nance v. Oliver, and later a separate civil action by Henegar’s family—alleging failures to protect incarcerated people. The AJC reported that prison staff ignored Henegar’s screams and other inmates’ pleas during a five-hour fatal attack, housed him with a mentally ill cellmate who had previously assaulted him, and kept Henegar in custody beyond his release date due to an administrative delay. GPS intel records note that the state settled the Henegar lawsuit for $4 million in 2026.

Georgia Diagnostic and Classification State Prison (January 2022–June 2023)
In his 18 months as warden at Georgia Diagnostic, 34 deaths occurred. GPS records list, among others, Kenneth Matthews (62), William Welland (40), Robert Carlton Savage (43), Elden Lamb (43), and Russell Lamar Nelson (58) in the first half of 2023 alone. An AJC homicide investigation identified multiple violent deaths: Carrell D. Johnson, 32, died of chopping injuries of the head and sharp-force injuries to the torso; Elmer W. Pless, 65, was strangled; Boyd Williams, 64, was manually strangled with blunt-force head trauma; Daniel Charriez, 46, died from delayed complications of a traumatic brain injury. Allegations in AJC and other news reports, cited in GPS intelligence, described a prison operating at 568% of its original design capacity, with almost every part vandalized, and gang-related violence routine. An officer admitted taking bribes from a death-row inmate, and a newly convicted person was found with a shank and contraband phone within days. A DOJ investigation, as reported by the AJC, found that Georgia’s prisons were riddled with regular violence and sexual assault. Caldwell was not named in any death-related lawsuits from this facility at the time, though Thrift v. Caldwell, a pending civil rights case filed in 2024, names him as a defendant.
