A man has been charged in the death of two people in their 20s last Friday.
A 42-year-old Elnora man faces two counts of dangerous operation causing death, impaired operation causing death, impaired operation of a motor vehicle and refusal to provide a sample.
The collision occurred on Highway 21, just north of Trochu.
Investigators determined that two cars were going northbound on Highway 21 when the second car rear-ended the first, causing it to drive across the road where it was hit by an oncoming semi-truck.
The two occupants of the first car, a 20-year-old female and a 21-year-old male, were declared deceased at the scene.
The 42-year-old has been remanded into custody and will be appearing in Drumheller Provincial Court on June 24.
