Shirley Ann Waquan, a 39-year-old member of the Mikisew Cree First Nation, vanished from downtown Fort McMurray, Alberta. She was last seen on July 1, 2007, and reported missing on July 5, 2007. At the time she had brown shoulder-length hair, brown eyes, a scar on her cheek, a tattoo reading SHIRL on her right wrist, missing several teeth, and scars on both hips. She sometimes used the names Dawn Robin Waquan or Shirley Anne Waquan.

Originally from Fort Chipewyan, Shirley had traveled to Fort McMurray for a medical appointment and did not return. She was known to be struggling with addiction and homelessness and was living in a wooded encampment in the city. Her son Shain reported her missing after his release from incarceration; he died in August 2022 without learning what happened to his mother. The Wood Buffalo RCMP opened an active investigation and conducted ground and water searches with Alberta Fish & Wildlife but found no trace. Very little public information has been released since.

Did anyone in Fort McMurray or Edmonton know Shirley or see her around late June and early July 2007?
