The woman injured in Wednesday evening’s collision on the Alaska Highway was medevaced to Vancouver in critical condition.

A hospital spokesperson said this morning her condition has been upgraded to stable.

A baby less than a year old in the same vehicle, a Honda Civic that ended up on the side of the road with the front driver’s side smashed in, was assessed by paramedics on scene and didn’t require further medical attention.

The two-vehicle collision occurred at about 6:45 p.m. near Trails North in Porter Creek.

The jaws of life were used to extricate the 25-year-old woman and infant from the car.

Witnesses reported seeing the driver of the other car, a Toyota Corolla, flee the scene on foot.

The suspect was found nearby by Whitehorse RCMP.

He was arrested and transported to Whitehorse General Hospital for treatment of injuries believed to be from the collision, police said in a news release issued later Thursday.

Ian Moore, 48, of Whitehorse has been charged with:

• failing to provide a breath sample;

• failing to stop at the scene of an accident; and

• causing bodily harm by street racing.

He was scheduled to appear in court this afternoon for a bail hearing.

The cause of the collision is still under investigation.

Alcohol consumption is believed to be a contributing factor, police said.

They are also investigating the possibility that a third vehicle was involved in the incident, and that two vehicles were street racing.

The Alaska Highway was partially closed at the time while an RCMP collision analyst worked on scene.

Anyone with any information about the collision is asked to contact Whitehorse RCMP at 667-5555.
