Sherri Leigh Green, 39, was found dead on September 17, 2009, inside her family’s cabin in the Old Campground area of Wasagaming in Riding Mountain National Park. Her body was discovered by one of her sisters and a brother-in-law; Wasagaming RCMP were called that evening and the investigation quickly expanded beyond the local detachment. An autopsy was performed in Winnipeg on September 19 and authorities publicly confirmed her death was a homicide, but police have not released the cause or manner of death.

Green was born in Brandon on August 23, 1970, and had worked in home care before retraining as a long-haul truck driver. She volunteered at Brandon General Hospital, assisted with community Christmas meals and enjoyed visiting Riding Mountain for camping and scenic drives. Media attention later included a man who identified himself as her boyfriend, Ontario trucker Mark Williton, who gave investigators a statement and denied involvement; he was never arrested or charged.

No arrest or charge has been publicly reported and the case remains an unsolved homicide. If anyone knew Sherri, her movements in early September 2009, or has information about the cabin at Wasagaming, please come forward.
