Police believe an SUV with four people inside lost control on the gravel road and rolled into a swampy ditch, where it landed upright in water.

Three people — a 21-year-old female driver, a 21-year-old female passenger and a male under the age of 18 were able to get out of the vehicle on their own, but told first responders a fourth person was still missing.

Police and EMS found the 21-year-old victim underneath the vehicle suffering from life-threatening injuries. She was rushed to hospital but later died.

RCMP say they’re sending condolences to the families and friends of all involved.
