Adam Clayton Lyle Jones, 23, of Gulf Breeze, Florida, was last seen by family on March 31, 2011, when he left home around noon driving a light blue Oldsmobile Delta 88. He reportedly took only a laptop and left other belongings and clothes at home. His last known destination was the Grand Canyon; his car was located at the south rim visitor center on May 5, 2011.

Rangers found an itinerary in the vehicle showing plans to visit cities in California and Denver, Colorado. Adam did not own a cellphone and his family did not file a missing person report until the car was discovered. Extensive searches around the Grand Canyon produced no sign of him, and no definitive evidence explains his disappearance.

Does anyone have information about Adam’s travels in March–May 2011 or remember seeing that Oldsmobile Delta 88 at the Grand Canyon?
