Jon Kevin Neff, 34, disappeared from Altamonte Springs, Florida, after leaving his parents’ home on Spring Lake Road on the morning of June 15, 1997, to work as a cook at the nearby First Watch restaurant. He phoned his workplace between 9:30 and 10:30 a.m. to say he would be late but never arrived, and he did not pick up his daughter later that day.

The next day picnickers in a remote area of Seminole Forest near the Wekiva River reported seeing a man matching Neff’s description sitting in a blue 1986 Oldsmobile Calais. The car was confirmed to be his, later found locked and abandoned at that location with his pager on the front seat. No signs of struggle were reported and an extensive search of the area produced no further clues.

Neff had been struggling with drug addiction and faced an outstanding cocaine-possession warrant; he had gone missing briefly before, but not for this length of time or without contacting his daughter. Investigators suspected foul play, and the case remains unsolved. Did anyone who knew Jon or who was in Seminole Forest that weekend see anything that could help explain his disappearance?
