A Canadian man arrested while crossing the border with $520,000 in cash remains in Spokane County Jail after appearing in U.S. District Court today.

Richard Paul Neumeyer, 66, of Kelowna, B.C., told federal agents he'd been transporting cash into the United States for a fee after he was arrested Friday at the border crossing in Laurier, Ferry County, according to court documents.

Federal agents say they found the cash - $510,000 in U.S. currency and $10,000 Canadian - in two hidden compartments in the floor of his 2006 Volvo about 11 a.m. Neumeyer said he had only $1,600 in cash when he arrived at the crossing, the U.S. Customs and Border Protection said.

When first interviewed by law enforcement about 7:25 p.m. Friday, Neumeyer said he was driving to Las Vegas for a three or four-day vacation but he had no plans once there and hadn't secured a hotel room, according to court documents filed today. He reportedly confessed to transporting cash - for a 2 percent cut - to Wickenburg, Ariz., about 60 miles northwest of Phoenix, 45 minutes into the interview.

Border records show Neumeyer crossed through Laurier on Jan. 7, Feb. 8, March 6, and April 21, according to court documents. He told federal agents he made $9,000 his first trip and $10,000 his second trip.

Neumeyer is to return to court on Thursday for a bail hearing on one count of failing to report currency under the Currency and Foreign Transaction Reporting Act.
