Richard Williams was 40 when he was found dead in the driveway of his Charleston, South Carolina, home on the evening of June 3, 2015. He had suffered fatal gunshot wounds, and investigators determined the shooting occurred during a drug deal that turned violent.

Police identified 35-year-old Walter Williamson of North Charleston as the person responsible for the shooting. Williamson was arrested and charged in connection with Williams’ death; court proceedings followed. The case concluded in April 2018 when Williamson pleaded guilty to voluntary manslaughter and received a 15-year prison sentence.

Anyone who knew Richard, his movements in Charleston in 2015, or has information about the circumstances of the deal or the shooting is asked to come forward.
