We've learned two people have been pronounced dead after a terrible crash on the TransCanada Highway Sunday afternoon west of Moose Jaw, near Parkbeg.

The initial investigation has revealed that the eastbound truck was carrying four people from out of province when it left the road and rolled just after 2pm, claiming the lives of two passengers. STARS sent a helicopter to the scene and took the driver along with another passenger to hospital.

No names have been released and RCMP have not said where the travellers were from.
