Alfonso James Spikes, a 61-year-old man from Miami, has been identified as the victim whose remains were discovered in the Florida Keys nearly four decades ago. In a breakthrough that highlights the power of modern forensic science, the Monroe County Sheriff’s Office, along with the Florida Department of Law Enforcement and the Monroe County Medical Examiner’s Office, confirmed his identity using advanced DNA sequencing and genetic genealogy.
Spikes’ body was originally found on May 4, 1988, off County Road 905 in north Key Largo under deeply troubling circumstances. His remains were in an advanced state of decomposition, wrapped in three sheets and concealed beneath trash. At the time, investigators were unable to determine who he was, and despite extensive efforts, the case eventually went cold. The medical examiner ruled the cause and manner of death as undetermined, though probable homicide was suspected.
Authorities believe Spikes was last seen in April 1988 after leaving his Miami home to meet an unidentified individual. Exactly how he ended up in Monroe County remains unclear, leaving lingering questions that investigators continue to pursue.
After a renewed effort began in December 2023, initial DNA testing yielded no leads. However, by June 2025, officials turned to more advanced methods, including genetic genealogy. By March 2026, those efforts paid off with a positive identification.
The investigation remains ongoing, and anyone with information is urged to contact authorities as they continue seeking long-awaited justice.
