A woman and two children are dead, and a third child is in critical condition, following a crash on Thursday in eastern Alberta. The woman was behind the wheel of an SUV and crossing Highway 16 at Range Road 14, west of Lloydminster, when her vehicle was struck by a westbound semi truck around 7:30 p.m. She died at the scene. The children – aged five, eight and nine – were taken to hospital in critical condition. The eight-year-old remained in critical condition as of Friday afternoon. Mounties say speed and alcohol were not factors but are still investigating. The highway was closed overnight.
