The chief suspect in the murder of three armoured vehicle guards has arrived in Edmonton and will appear in court on Thursday.

Travis Baumgartner was flown out of Surrey, B.C. and arrived in Edmonton shortly before 2 p.m. local time. An RCMP plane arrived at the city's airport, and shortly after, three police cars, one with blacked-out windows, drove away.

An RCMP spokesperson would not confirm that Baumgartner had arrived in Edmonton. However, one of the force's planes arrived at the city's airport just before 2 p.m. local time.

Three police cars, one with blacked-out windows, were then spotted driving out of the airport.

Baumgartner is expected to face three counts of first-degree murder and one count of attempted murder related to a fourth guard who is in critical but stable condition.

Baumgartner is expected to be charged with four counts of armed robbery.

Police allege Baumgartner was part of a crew of five G4S security guards who were re-loading an ATM machine at the University of Alberta's Edmonton campus early Friday morning, when the robbery took place.

After a two-day manhunt, Baumgartner was detained by U.S. border officials late Saturday night attempting to cross the border near Abbotsford, B.C. into Washington. He was then arrested by RCMP officers.

He had no passport and was carrying over $300,000 in cash in his pickup truck at the time.

Baumgartner had been held in a remand centre in Langley, B.C. until Wednesday.

On Tuesday, the wife of the guard who survived the attack, provided an update on his condition through the Canadian Forces, saying Matthew Schuman remains in critical but stable condition.

The woman, has asked to have her surname withheld, said her husband opened his eyes at least once and squeezed her hand.

She said she is cautiously optimistic that Schuman's condition will improve.
