Jacob Olivier, 23, was last seen on August 24, 2011, when he drove alone into Everglades National Park near Homestead, Florida, in a dark green 1998 Isuzu Hombre. Surveillance footage showed him arriving at about 1:00 p.m., and his cell phone last pinged at 4:45 p.m. that day. Rangers found his truck abandoned at the Pine Glades Lake trailhead on August 27 with no sign of Jacob nearby.

His family did not know he was in Florida until the vehicle was located. No drugs were found in the truck despite a past history of drug use and rehabilitation. A gun case was in the vehicle but no firearm was inside. An extensive search of the Everglades was conducted and was called off in September 2011 with no significant leads. There have been no confirmed sightings since, only unconfirmed reports placing him in the Savannah, Georgia, area.

What information might help explain why Jacob traveled to the Everglades or where he went after his phone last pinged at 4:45 p.m.?
