A day after two people were killed and two others injured in a serious collision on Highway 63, family of two people involved shed light on the occupants of one of the vehicles.

CTV News has learned the occupants of one of the vehicles were Juliette Germain, 52, and Jayden Rosario, 7.

Germain was pronounced dead at the scene – Rosario, her grandson, remains in critical condition in hospital.

On Sunday, Boyle RCMP said the crash happened about one kilometre north of Wandering River on Highway 63 that morning.

Police said at the time that the vehicle Germain was driving pulled out in front of another vehicle going in the opposite direction – and the collision happened at highway speed.

Of the two occupants of the other vehicle, a 28-year-old male passenger was pronounced dead at the scene, the 26-year-old driver of that vehicle was rushed to hospital in Lac La Biche with life-threatening injuries.

The Germain family said Juliette was in the area for a family reunion, and a number of members of the family were on their way to church at the time.

Her father said he turned onto the highway just before his daughter – and saw the collision unfold through his rear-view mirror.

He admitted his daughter made an error, but the family maintains fewer deaths would occur on the highway – often called the “Highway of Death” – if the highway was twinned.

RCMP also said driver error is to blame for the crash.

The Minister of Transportation said the province is working on twinning the highway.

“We are trying to do everything we can, we are very active on the file,” Minister Ric McIver said. “This is one of those very odd accidents, if someone is turning left, and the road was twinned, there would actually be more lanes to get passed safely than there is now.”

Jayden Rosario will turn 8 next month.

The names of the other two people involved in the crash have not been released.
