On the morning of March 22, 2014, 25-year-old Antwan Mario Dixon of Camden, South Carolina was found slumped in the driver’s seat of a 1999 Ford Taurus that was burning in a ditch near the intersection of Black River Road and Pathfinder Trailer. Deputies say Dixon was pulled from the vehicle and airlifted to Palmetto Richland Hospital in Columbia, where medical staff discovered a gunshot wound to his head. He died about 12 hours after being rescued.

Investigators treated the case as a homicide after finding multiple bullet holes in the car and numerous spent shell casings on the roadway, indicating shots were fired before the crash and fire. The Kershaw County Sheriff’s Office interviewed witnesses and people who had been with Dixon earlier that morning. Authorities later identified 22-year-old Robert Wendell Simon as a person of interest; Simon surrendered on April 1, 2014, and was arrested and charged with Dixon’s murder.

If anyone saw activity near Black River Road and Pathfinder Trailer that morning or knew Dixon’s movements before the crash, please share what you know with investigators.
