Tenure Summary
Mark Agbaosi has risen through the Georgia Department of Corrections from correctional officer to Warden over a 15‑year career. GPS records attribute 56 deaths to the facilities where he held leadership roles — 46 at Georgia Diagnostic and Classification State Prison and 10 at Dooly State Prison. Two federal civil‑rights lawsuits naming him as a defendant are currently pending, and a third lawsuit was filed during his tenure as Deputy Warden.What happened on their watch
Agbaosi began his career at the Georgia Diagnostic and Classification State Prison in 2010 as a correctional officer, later serving as a sergeant, captain, and unit manager at the same facility before being promoted to Deputy Warden in 2023. Across those years, GPS counts 46 deaths at Georgia Diagnostic. The record shows that during his time as Deputy Warden alone, more than 30 people died at the prison. Among them were Carrell D. Johnson, whose death according to an AJC investigation was caused by “chopping injuries of the head and sharp‑force injuries of the torso,” and Elmer W. Pless, who the same investigation found died of strangulation. The facility operated under extreme strain: reports document that the prison held 4,540 people — 568% of its original 800‑person design capacity — and infrastructure had been widely vandalized. During this period, AJC investigations revealed that officer Vera Jackson admitted receiving thousands of dollars to provide a death row inmate with information on upcoming shakedowns, another inmate was found with 35 contraband cellphones, and a newly arrived prisoner possessed a homemade shank and a cellphone within days. A lawsuit, Thrift v. Caldwell, was filed in January 2024 while Agbaosi served as Deputy Warden, and GPS also received reports alleging medical neglect for prisoners with chronic conditions.Agbaosi became Warden of Dooly State Prison in January 2025. GPS attributes 10 deaths to his tenure there. Several were homicides: Joshua Parrott died of strangulation, Horario Philmore was listed as a homicide, and a user report states that Darrow Brown was “killed on the walk while being escorted back to his building … by a member of the Crips gang.” Other deaths with publicly reported causes include Timothy Glenn Williams (listed as “Natural/Drug OD”), while the cause for Dexter Andres Levy, Paul Counts, Willie Mote, Marshall Davis Crews, Orlando Perez Glass, and Samuel Jacob Blackmon remains unspecified. Violent incidents marked the first year: gang‑related fights on March 23, April 1, and May 22, 2026, sent multiple inmates to hospitals, some by helicopter, and prompted a statewide lockdown. An investigation found housing units with no officer supervision for hours or entire shifts. In December 2025, a corrections officer cadet was caught trying to smuggle 640 grams of pure methamphetamine into the prison; he pleaded guilty. Inmate Abraham Rivas was charged with running a phone‑fraud scheme from Dooly, and according to news reports he claimed that correctional staff were aware of similar scams. Allegations of medical neglect surfaced in an AJC report, and a family member told Georgia Public Broadcasting that medical staff “put his father’s treatment ‘on the back burner,’ contributing to his death from sepsis.” The lawsuit Robertson v. Agbaosi was filed against him in February 2025, and Miller v. Holt was filed in August of the same year.
