November 19, 2006. Littleton, Colorado. First Lieutenant Nonnie Dotson, a 33-year old nurse with the United States Air Force, has travelled from San Antonio, Texas to Colorado with her infant daughter and is saying with her brother, Tony Dotson. Nonnie leaves Tony’s residence in order to presumably travel to a nearby shopping center, but she never returns. Even though police track Nonnie’s cell phone signal and her scent to a nearby field, no trace of her can be found. Investigators explore a number of different angles, including the possibility that Nonnie was harmed by a stalker, the estranged father of her child, and even her own brother, but she remains a missing person. On this week’s episode of “The Trail Went Cold”, we explore a baffling unsolved disappearance in which the victim seemingly vanished into thin air.
