In the fall of 2003, Felipe Santos, a 23-year-old undocumented migrant worker from Mexico went missing after a minor fender bender in Naples, Florida. Three months later, 27-year-old Terrance Williams disappeared from the same stretch of road. Both were men of color and both were last sighted in the back of a police car, driven by the same white Sheriff's deputy. Today, we bring you the first episode of "The Last Ride," an investigative series exploring why, nearly 20 years later, these disappearances remain unsolved.
