Mark Randall Davis was 20 and a Texas A&M student when he was last seen on January 15, 2007, in Tyler, Texas, while home for winter break. He had recently switched his major from chemical engineering and economics to Spanish and had stopped attending most classes except Spanish. Family members found he was gone early that morning; his wallet, cell phone, money and a note saying they would never see him again were left at home. He took his father’s green and silver 2005 Expedition mountain bike, which was also missing.

Before his disappearance Mark showed signs of depression and had seen a therapist who did not consider his condition severe. In the days prior he appeared withdrawn and uncertain about his future, and his parents said he might have been thinking about moving to Latin America, though his passport was left behind and never renewed. Several unconfirmed sightings followed but no solid leads have surfaced and the case remains open.

If anyone saw Mark or the bike around Tyler in mid-January 2007, can you share what you remember?
