The remains of a British Columbia woman missing for a dozen years have been found on a rural property in Vanderhoof, the RCMP said Monday.

The announcement of the discovery came 12 years to the day after Madison Scott was reported missing by a family member.

Police have said she was 20 years old when she was last seen early in the morning of May 28, 2011.

She had been at a party celebrating a friend’s birthday at Hogsback Lake outside Vanderhoof, in central BC

RCMP said in a news release issued Monday that Ms. Scott’s remains were found “days ago” in the search on the property but couldn’t say exactly when and where they were located.

North District RCMP said officers were on scene executing a search warrant on the property.

Police said Ms. Scott’s remains have been positively identified by the BC Coroners Service, and the family has been told and has asked for privacy.

RCMP Corporal Madonna Saunderson said the discovery was a “significant development” for the ongoing investigation, and foul play has not been ruled out.

The police issued a statement Sunday on the anniversary of her disappearance saying they needed the public’s help in finding her.

“Early in the investigation, the police determined that it was out of character for Madison not to be in contact with her family and or friends,” said the statement.

It said the young woman was vibrant, free-spirited, loyal and kind.

“When not working hard at her parents’ family business, Madison immersed herself in family, friends, hockey, softball and photography. This year, Madison would be 32 years old. She would likely be immersed in her career and may even have gotten married and had children,” the police statement said.

The family has offered a $100,000 reward for any information leading to the arrest and laying down of charges of those responsible for her disappearance.
