Doug Bruce has been found guilty on all counts in his criminal tax fraud case.
Jurors heard closing arguments Wednesday after eight days of testimony. They deliberated for less than four hours before coming to the guilty verdict.
Douglas Bruce, the author and proponent of the constitutional amendment called the Taxpayer Bill of Rights was found guilty of evading state taxes, filing a false return, and attempting to influence a public servant and failing to file a return between 2005 and 2010.
During testimony, prosecutors alleged that Bruce owes taxes on $178,000 interest gained on the millions he deposited into the anti-tax charity that he operated and which he used to support ballot initiatives.
Bruce argued that none of the interest ended up in his pocket and says the state filed the case out of revenge for his political views.
Bruce is scheduled to be sentenced at 1:30 p.m. on February 13, 2012 in Denver District Court. He could face up to six years in prison or up to $500,000 in fines on attempt to influence a public servant, a class-four felony and the most serious charge Bruce faced. The maximum sentence he faces for all charges is 12 years.
