The bill H. 5191 is a concurrent resolution introduced in the South Carolina General Assembly to honor Detective William A. Singleton by naming a portion of Black Street in Rock Hill, York County, as "Detective William A. Singleton Memorial Street." The designated section runs from Albright Road to Orange Street, and the resolution requests the Department of Transportation to erect appropriate signs or markers at this location to commemorate his legacy.

Detective Singleton, who served in the Rock Hill Police Department, was killed in the line of duty in 1968 while attempting to protect a civilian from gunfire. His actions not only saved a life but ultimately cost him his own. The resolution highlights his dedication to law enforcement and his sacrifice, noting that he was posthumously inducted into the South Carolina Law Enforcement Hall of Fame in 1980. The resolution aims to ensure that his memory is preserved and honored within the community.
