Elito Castro, 53, was last seen in Jacksonville, Florida, on July 25, 1988.

The Jacksonville Sheriff’s Office maintains a Cold Case Unit and has revisited Castro’s file as part of broader efforts to re-examine unresolved disappearances from the 1980s and 1990s. Investigators note the limitations of forensic technology at the time and say advances in DNA and other methods could eventually produce new leads.

Anyone with information, however small, about Elito Castro’s whereabouts or movements before July 25, 1988, is asked to contact the Jacksonville Sheriff’s Office.
