Report records dated January 2026 state Dooly held 1,593 people in a facility designed for 500, with correctional officer vacancies averaging 50% statewide, and a November 2025 investigation described housing units with no officer supervision for hours or entire shifts. Media and submission records during his wardency describe repeated violence: a gang-related dormitory fight injuring five inmates (March 23–24, 2026); a gang-related fight injuring six inmates with three airlifted (April 1, 2026); a gang-related fight injuring nine inmates that prompted a statewide lockdown of all GDC facilities and Memorial Day visitation cancellations at Dooly, Washington, Ware and Hancock (May 22, 2026); a three-inmate altercation with one hospitalized (June 7, 2026); and a statewide lockdown following a gang-related fight that left nine injured (June 11, 2026). Unverified GPS web submissions describe stabbings and lockdowns across 2026, a mass stabbing with multiple injured, and a person transported to a hospital after a head injury. An April 7, 2025 allegation states an inmate named David was beaten by Lt. Fudge and a CERT team after requesting a protective transfer, and an October 1, 2025 event record states inmate Zeary "Blue" Davis was stabbed at the facility.

Other allegations at Dooly during his wardency: GDC cadet Julius Deshawn Williams Jr. was found with 640 grams of methamphetamine intended for an inmate, pleaded guilty in December 2025, and was sentenced August 20, 2026 to 10 years plus five years supervised release, per WGXA and the U.S. Attorney's Office for the Middle District of Georgia. Abraham Rivas was charged with an organized scheme to defraud and grand theft for impersonating a Flagler County Sheriff's Office deputy to obtain $1,000 routed to his prison commissary account (WALB, Wesh.com, News-journalonline.com); Rivas claimed other inmates ran similar scams and that correctional staff were aware.
