(KMZA)--A St. Mary's man is going to federal prison, sentenced Thursday to five years behind bars for tax evasion.

According to U.S. Attorney Tom Beall, 71-year-old David Pflum was also ordered to pay more than $8.4 million in restitution.

Pflum, the owner of Coil Springs Specialties, was found guilty in January on one count of tax evasion and one count of obstructing the Internal Revenue Service.

During the jury trial, the prosecutor presented evidence that Pflum submitted false documents claiming he had less than $475 in assets and his income was $470 a month. In fact, he owned more than $2 million worth of real estate and his income was more than $16,000 a month. He urged renters, buyers and others indebted to him to ignore collection efforts by the IRS.
