On Monday, December 13, 2004, Stephan Mitchell Adams completed a final examination at Northeastern State University (NSU) in Tahlequah, Oklahoma.

Stephan told his girlfriend that he was giving a man a ride to Keys, Oklahoma, and that he would call her right back. Stephan intended to visit his mother in Webbers Falls, Oklahoma. Since this date, Stephan has missed work, other final examinations, and has had no contact with his family or friends. Stephan’s absence is considered suspicious. (Information retrieved from FBI.gov)
