"..immigration officials say the Connors didn't make a mere navigation error, with Customs and Border Protection agents telling Fox News in a statement Wednesday that authorities first spotted the vehicle around 9 p.m. on Oct. 2 and proceeded to track it through video surveillance as it drove on Avenue 0 in Canada before it "turned south and entered the U.S. illegally, by slowly and deliberately driving through a ditch onto Boundary Road in Lyndon, Washington."
Officials say the car continued to travel west on Boundary Road before the vehicle was finally pulled over by a Border Patrol agent "a short time later." All seven people inside the car were identified as citizens of the United Kingdom, and were arrested for entering the U.S. illegally.
Immigration officials said that, while the family members were being processed, records revealed two adults in the group had been "previously denied travel authorization to come to the United States...."
