Michaelle Marie Champagne, a 29-year-old Belgian native, vanished after two brief contacts in 1993. The family’s last confirmed communication was a March 9 call from Washington D.C. saying she had arrived safely from Belgium and planned to sightsee before returning to Spokane. Agencies also cite an unconfirmed sighting by her then-boyfriend on June 1, 1993, and the boyfriend later told police they split on March 17 and that he last saw her in June riding a motorcycle in the Spokane area.

Her live-in boyfriend did not report her missing until September 8, 1993. Investigators found he had used her credit cards, sold furniture from storage and a jointly owned car in the months after her disappearance, and stayed alone in a Spokane motel after returning from Washington D.C. Detectives consider homicide a possibility. DNA from her parents and brother was collected in 2011 to compare with unidentified remains, but the case remains unsolved.

What can readers who knew Michaelle, her movements in Spokane, or the people she spent time with in early 1993 add to this investigation?
