During this tenure, reports reaching GPS describe gang-related fights — including one on May 22, 2026 in which nine incarcerated people were injured and GDC placed all its facilities on lockdown, with visitation cancelled at Dooly and three other prisons — an altercation involving three people on June 7, 2026, repeated reported stabbings across 2026, and an April 2026 gang-related fight in which six were hospitalized and three airlifted. A November 2025 report described housing units with no officer supervision for hours or entire shifts; January 2026 reports described 1,593 people held in a facility designed for 500 with roughly 50 percent vacancy rates and inadequate medical, food-service and staffing infrastructure. An October 2026 inside report to GPS alleged a roughly 17-hour gap between the evening meal and breakfast against a policy maximum of 14 hours, and other reports described a tactical squad entering a housing unit overnight and a disturbance in which about a dozen officers entered a unit and an incarcerated person was reportedly struck. An inmate report from August 21, 2026 states an incarcerated person was reported dead at Dooly with cause unconfirmed and the facility in lockdown. WGXA reported that former GDC cadet Julius Deshawn Williams Jr. smuggled 640 grams of methamphetamine into the prison; he was sentenced August 20, 2026 to 10 years plus five years supervised release. WALB and Wesh.com reported that Abraham Rivas was accused of impersonating a Flagler County Sheriff's Office deputy to defraud a Florida resident of $1,000 sent to his commissary account, and that Rivas claimed staff were aware of inmate scams — an allegation attributed to him. Event records also describe an inmate named David beaten by Lt. Fudge and a CERT team on April 7, 2025 after requesting protection from gang threats, Zeary "Blue" Davis stabbed in October 2025, and Deputy Warden Charles Hudson bitten by an inmate in December 2025. An anonymous Facebook comment alleged a multi-week commissary shortage in 2025.
