Police said Sunday that triple-murder suspect Travis Baumgartner is being held in custody in Langley, B.C and anticipate he will be transferred back to Edmonton within the next week.
EPS Supt. Bob Hassel said five homicide detectives and three forensics investigators flew into Langley Saturday night and are currently sifting through evidence and interviewing Baumgartner.
Baumgartner, 21, was arrested without incident around 4 p.m. Saturday at the Lynden, WA U.S.-Canada border south of Abbotsford, B.C.
"I'm very happy with the way that it ended, that it ended peacefully," Hassel said.
"We're extremely grateful to the RCMP and the border officials of Lynden, Washington and all of our policing partners who helped bring this dangerous suspect into custody in such a quick manner."
Police say Baumgartner attempted to cross the border using his Alberta driver's license.
Automatic license plate scanners alerted border patrol officials.
"Our officer in the booth got an instant warning that this vehicle is associated to someone armed and dangerous," said Thomas Schreiber with U.S. Customs and Border Protection.
"Our officers extracted Mr. Baumgartner from the vehicle. He complied with our orders."
Officials searched Baumgartner's truck and did not find any weapons, however a backpack with around $330,000 in cash was discovered.
Police say Baumgartner was arrested by RCMP on Canada-wide warrants for three counts of first-degree murder, one count of attempted murder, and four counts of armed robbery.
They expect Baumgartner to appear in B.C. court Monday to answer to those warrants before he can be brought back to Edmonton and formally charged.
Another media update is scheduled for Monday morning.

Baumgartner is a G4S Security armoured guard suspected to have shot and killed three of his armoured guard colleagues and put a fourth guard in hospital with life-threatening injuries.
Baumgartner spent nearly 36 hours on the run, prompting an international manhunt.
G4S employees Michelle Shegelski, 26, Brian Ilesic, 35, and Eddie Rejano, 39, were shot and killed in HUB Mall at the U of A Friday.
A fourth victim Cpl. Matthew Schuman, 26, remains in hospital with life-threatening injuries.
News of Baumgartner's arrest left a sense of relief and some comfort for some families of the victims.
The families were notified of the arrest by police.
Shegelski's uncle told CTV News shortly after the arrest that they're happy the suspect has been caught but it does little to ease the pain they've had to endure.
"It's a little bit of a sense of relief but the fact remains that Michelle's gone and was taken from us," said John Ernst, Shegelski's uncle.
"We're just trying to deal with that loss."
Police say news of the arrest has brought some level of relief to the G4S family.
"We applaud the dedication of the Edmonton Police Service, and other law enforcement agencies in apprehending Travis Baumgartner today," G4S spokesperson Robin Steinberg said in a statement.
"Our thoughts remain with the families and friends of the victims and also with the Baumgartner family."
Steinberg said G4S is conducting their own detailed investigation into the incident.
