BANGOR (AP) – A British woman’s swim across the St. John River from Canada has landed her in the Penobscot County Jail.

Katharine Mary Hiscox, 33, was detained following her appearance Monday in U.S. District Court on charges of entering the United States without inspection and being in the country after deportation.

Hiscox, whose hometown was not listed in court documents, did not enter a plea to the charges. If convicted, she faces up to two years in prison and a fine of up to $250,000.

The woman, also known as Kate Pagram, was deported in January from Atlanta and barred from re-entering the United States.

Hiscox allegedly swam across the river Saturday night and was soaking wet when she knocked on the door of a home in Fort Kent sometime between 11 and 11:25 p.m., according to court documents.

The homeowner called police Sunday morning to report that he had driven the woman to the Blue Sky Hotel in Madawaska. U.S. Border Patrol agents arrived at the hotel only to find that she had checked out 30 to 45 minutes earlier.

After an alert to border officials, agent Dennis Harmon followed a Madawaska-based taxi heading south on U.S. 1 in Littleton about noon Sunday with a female passenger. When the cab pulled into a gas station and convenience store in Houlton and the driver went inside, Harmon approached the cab, he said in an affidavit.

“The passenger opened her door and when I asked, the passenger stated that she was a citizen of Great Britain. She spoke with an English accent. I asked her how she had entered the country and she said she swam across the St. John River. I then asked her if she had been admitted by a Customs and Border Protection Inspector and she answered no,” Harmon wrote.

Hiscox and a female traveling companion from the United States had been staying last week at a hotel in Edmundston, New Brunswick, according to court documents, and Hiscox said her friend was unaware of her plans to enter the United States illegally.

Hiscox allegedly told agents that the two women planned to meet Saturday night in Fort Kent, but they apparently missed each other. The American woman’s car was being inspected at the Fort Kent border crossing at 11:29 p.m., about the time Hiscox was being driven to the hotel, according to court documents.

Inside the car, agents found a subpoena for the state of North Carolina for Kate Pagram, a tax bill from Somerset, England, for Catherine Hiscox, an Internet printout for two English bank accounts held by K.M. Hiscox and suitcases containing women’s clothing in two different sizes.

Because she was a U.S. citizen and did not possess any contraband, Hiscox’s friend was allowed to enter the country and no charges were filed against her.
