Last night, at around 9:30 pm, Prairie Mountain RCMP responded to a single-vehicle rollover in the RM of Rossburn.
The vehicle contained four people from Waywayseecappo First Nation and it was travelling west on Road 144 when it left the road and rolled several times. One of the occupants was thrown from the vehicle.
A 45-year-old female and a 31-year-old male were pronounced dead on the scene.
A 47-year-old male and a 32-year-old male were taken to hospital with non-life threatening injuries.
Police believe that the occupants were not wearing seatbelts, and speed is considered a factor in the accident.
RCMP continue to investigate.
