TULSA, Okla. – A former chief financial officer for a company with offices in Oklahoma pleaded guilty in federal court after failing to pay over to the IRS $3.6 million in income and FICA tax withholdings and for embezzling more than $130,000 from the company. Paul B. Bowker, 60, a British national, fled the United States three years ago after being charged with the crimes. The U.S. Attorney’s Office eventually received a tip that led to Bowker’s arrest by local authorities in the United Kingdom. The Justice Department's Office of International Affairs worked with officials from the United Kingdom to ensure Bowker's extradition to the United States for prosecution.
