Summary based on the NamUs case record (MP65162) and 2 other sources
Martin Franklin Blue, a 61-year-old man from Miami, Florida, was last seen on July 19, 2018. His disappearance was sudden, and no one has heard from him since that date. Blue, who did not have any known mental or physical disabilities, had not reported to work or contacted anyone after his disappearance, raising concerns about his safety and well-being. There is very little information available regarding the circumstances leading to his disappearance, and investigators have not uncovered significant leads.

Standing at 6'4" and weighing 240 pounds, Blue's case remains open, and law enforcement has requested the public's assistance in locating him. The Miami-Dade Police Department continues to investigate the case, but so far, no further details have been made public regarding potential sightings or developments in the investigation.

Anyone with information is encouraged to contact local authorities to help provide answers in this case.
