A Denver District Court judge sentenced Jack Thomas to 10 years probation for failing to pay more than $60,000 in state taxes, penalties and interest.

Thomas, a Black Forest resident and commercial airline pilot, did not pay state taxes between April 2004 and April 2008. Thomas defended himself throughout his trial by alleging erroneous issues, including that he did not earn any wages as defined by the government, said Colorado Attorney General John Suthers.

A Denver jury convicted Thomas of evasion of taxes, a class five felony; fraud by check, a class six felony; forgery of checks, a class five felony and filing a false tax return, a class five felony.
