Edmonton police are confirming that the man wanted in a deadly armoured car heist at the University of Alberta has been apprehended. Travis Baumgartner, 21, was stopped at a border crossing in Lynden, Washington, south of Abbotsford, B.C. Officers say he was still driving his dark blue F-150 pickup truck and was alone at the time of the arrest. On Saturday afternoon, police said an "international manhunt" was launched following Friday morning's deadly shooting, where three G4S guards were killed and another was wounded. Police have said Baumgartner was the fifth member of the crew reloading bank machines at a mall and residence. Efforts are now being made to bring him back to Alberta to face three counts of first-degree murder and one count of attempted murder. In a release, Edmonton police say news of the arrest has brought some solace and relief to the G4S family, who are "still in a state of shock". A news conference is now slated for Sunday afternoon at 1pm MST to update the situation.
