The Canadian border guard shot in her booth at the Douglas Border Crossing in Surrey, B.C. is in stable condition in hospital, police said Wednesday.

The female guard, identified as Lori Bowcock, was airlifted to hospital Tuesday after being shot by the lone gunman entering Canada from the United States.

It appears the bullet struck her in the neck, RCMP said.

She remains in "stable" condition, said Sgt. Jennifer Pound of the RCMP’s Integrated Homicide Investigation Team.

Peter Leon, of the Ontario Provincial Police, told CTV News that Bowcock had previously worked as a dispatcher at the OPP's communications centre in London, Ont.

“As an organization she was part of before, we are concerned with her well-being and her recovery,” Leon said. “Our thoughts go out to her family at this time.”

The male suspect, reportedly named Andrew Crews, was driving a white van with Washington state licence plates, but it’s unclear whether he actually owned the vehicle. The vehicle was traced to a home in Bremerton.

Politicians in British Columbia and Washington have said that both jurisdictions will work together on the shooting investigation, which includes surveillance tape and witness testimony.

Washington Governor Chris Gregoire said Tuesday that she considers the Canadian guards at Douglas Border Crossing an “extension of the Washington family.”

Luc Portelance, President of the Canada Border Services Agency, has called the incident a “profound reminder of the risks that border services officers assume every day.”

A source at the Customs and Immigration Union that represents Canadian border guards told CTV News that a male suspect shot himself in the head and the bullet hit the guard accidentally, but police said they are still treating the incident as an attempted homicide.

The Douglas Border Crossing, which links Surrey and Blaine, Washington, is also known as the Peace Arch border. About 4,800 vehicles pass through the crossing during peak periods.

The crossing remained closed to traffic Wednesday morning. DriveBC, a travel information agency, estimates the crossing will re-open at 4 p.m.
