TAMPA, Fla. (AP) - Two Tampa area men have been sentenced for taking part in a tax scheme to defraud the IRS.
The U.S. Attorney's Office says 54-year-old Gregory F. Guido and 78-year-old George B. Calvert were sentenced this week for conspiracy to defraud, commit wire fraud and illegal monetary transactions. Guido received nine years. Calvert was sentenced to seven years.
Jurors found them guilty on June 21.
The St. Petersburg Times ( ) reports that from 2003 to 2006 the men identified landfills and claimed they had the rights to any methane gas produced there. Prosecutors say they sold the rights as fraudulent tax credits.
Authorities say they faked engineering reports and landfill purchase agreements to make the operation look legitimate.
Co-conspirator Robert Henry Anderson's sentence was reduced after he aided in the investigation.
