Stephen Craig Lund was 32 when he was last seen in Tampa, Florida, on August 4, 1979. He had told his family in Illinois he planned to return by July 4, 1979, but he never arrived. Reports indicate he was believed to be traveling with Suzanne Schultz, then 17, who had told her family from Tampa she would be home by August 4 but also never reached her destination.

In September 1979 a U-Haul trailer belonging to them was found abandoned in Chicago, Illinois. Aside from that discovery, there has been no confirmed trace of either Lund or Schultz and the disappearances remain unsolved. If anyone knew Stephen or Suzanne, their travel plans, or saw that U-Haul in or around Chicago in September 1979, please share what you know.
