An American truck driver has been arrested and charged with the possession, importation and creation of child pornography at the Beaver Creek border crossing.

Aaron Finn, 56, from Oregon, had delivered a shipment of plants to Alaska from the southern U.S. when he was detained by Border Services agents on May 28.

Finn was referred for a secondary examination at the Beaver Creek border crossing, during which his travel history was reviewed, Faith St. John, a Canadian Border Services Agency communications officer, told the Star today.

St. John said a secondary examination is part of the normal customs process.

Anytime a border agent wants to ask a few more questions, the person is referred for a secondary check.

After reviewing the trucker's travel history, the border agents discovered he frequented countries including Cambodia, Thailand and the Philippines, "source countries of child sex tourism and child pornography,” the RCMP said in a statement released today.

An examination of Finn's vehicle and its contents found suspected child pornography on his computer, which included "a number of nude images of (Finn) with young females.”

Finn was then arrested by Beaver Creek RCMP. He is currently being held in Whitehorse.

The RCMP are working with the Canada Border Services Agency, the B.C. RCMP Integrated Child Exploitation team, U.S. Homeland Security and the U.S. Attorney's Office to complete the investigation.

Sgt. Don Rogers of the Whitehorse RCMP said today Finn does not appear to have a previous record in Canada.

An estimate of the ages of the children involved was not available.

However, Const. Patrick Poulin of the Beaver Creek RCMP said, "You have to have sufficient grounds to believe that those females or males were under the age of 18; they appeared to me to be under 18.”

Poulin was not sure how many pictures Finn was allegedly in possession of.

"The search has to stop when you have sufficient evidence that a crime has been committed,” he said.

A search warrant is then obtained and the evidence is sent to a specialized lab.

There, a more complete assessment of what the electronics contain will be conducted.

When the lab completes its assessment, there will be a better understanding of where the pictures were taken, the ages of the victims and the quantity, said Poulin.

Finn is scheduled to appear in court June 13.

In 2011, 5,200 commercial vehicles and 280,000 passenger vehicles passed through the Beaver Creek border crossing.
