On the morning of February 17, 2008, Marilyn Bergeron (born December 21, 1983), left her family's home in Quebec City, Quebec, Canada, for what she said was a walk.
She did not return.
An automated teller machine (ATM) security camera in Loretteville recorded her attempting to withdraw money early in the afternoon; she was last seen almost five hours after leaving home at a coffee shop in Saint-Romuald.
Many sightings of her have been reported since then, especially in areas of Ontario just outside Quebec, but none have been confirmed.
Quebec City police (SPVQ), who continue to investigate, have theorized that Bergeron committed suicide.
Her family, who has put up a reward for information leading to the resolution of the case, believes she may have instead met with foul play.
As a result, they have retained former provincial justice minister Marc Bellemare to press their case.
Crime journalist Claude Poirier has also devoted an episode of his Historia series Poirier EnquĂȘte to the case.
In 2017, a friend who knew Bergeron in Montreal confirmed that she had grown increasingly fearful and reclusive there in the two months before her disappearance.
He said he had asked her if she had been raped or witnessed a crime.
She said what had happened to her was "worse" than that, but refused to elaborate.
