More details are emerging about the arrest of Travis Baumgartner, 21, at the Lynden, Washington U.S.-Canada border, south of Abbotsford, B.C.
Mike Milne is with U.S. Customs and Border Protection.
He says Baumgartner arrived on Saturday afternoon in a blue pickup truck with Alberta license plates.

Milne says their automated plate readers read the plates and identified Baumgartner as an armed and dangerous suspect.
Milne says the young man from Sherwood Park surrendered without incident and a substantial amount of money was then discovered in his truck.
"A large sum of Canadian currency was found in the vehicle," remarked Milne. "Over $330,000 worth of Canadian currency. Mr. Baumgartner is currently being processed for removal from the United States and he, along with his vehicle and any evidence found will be turned over to Canadian law enforcement authorities for processing."
Milne expected Baumgartner to be turned over to Canadian authorities late Saturday night.
He says Baumgartner was unarmed, with no guns found in his vehicle.
Baumgartner was wanted on Canada-wide warrants on three counts of first degree murder and one count of attempted murder.
He stands accused of the fatal shootings of three of his fellow co-workers as they loaded an ATM at the University of Alberta.
At last report a fourth armored guard shot at the Hub Mall early Friday morning was in critical condition in hospital. (td, kdr)
