MANNING — The Manning Police Department fired officer Alexander Dukes on Wednesday, Oct. 21, 2026.
In 2010, the Sumter County Sheriff’s Office dismissed Dukes after nearly 15 years of service. About five months later, the Manning Police Department hired him.
His 2026 dismissal followed a State Law Enforcement Division review connected to his son, Antwone Dukes. Antwone Dukes faces two murder charges in the Oct. 6, 2026, shootings that killed Keywaun Clark, 20, and Derek Parson, 19, outside a Dollar General on Race Track Road in Sumter County.
According to South Carolina Criminal Justice Academy records, Alexander Dukes treated his son’s wound at home after the shooting and sent him to the hospital without calling 911. The records also describe texts suggesting he passed along roadblock and traffic-stop information, a failed polygraph, and a SLED review of possible misconduct in office. The Academy suspended his certification Oct. 8, 2026. As of late October 2026, he had not been charged with a crime. The claims described in the Academy records remain allegations.
Chief Sean Briley said the department placed Dukes on leave after outside agencies alerted it, then fired him after learning more.
