A Tucson man was sentenced to 10 years in state prison Monday after being found guilty of a chemical bomb attack.
Todd Russell Fries, former owner of Burns Power Washing, is already serving time in federal prison for earlier convictions in the same case.
He was sentenced Monday in Pima County Superior Court on state charges after a jury found him guilty in March of two counts of attempted first-degree murder. He also was convicted of 22 other charges, including arson, kidnapping, aggravated assault with a deadly weapon, and endangerment.
The charges stemmed from an elaborate campaign of terror aimed at two former clients of Friesβ company on Tucsonβs northwest side.
The plot began with a dispute over a few hundred dollars and culminated with the burning of chlorine tablets mixed with other chemicals outside a coupleβs home in 2009. Their front door was sealed so they had to escape the house through a back door, where the found another smoking device.
The fire spewed a chlorine plume that prosecutors said spread a mile wide over the neighborhood.
Friesβ campaign against the couple also included writing anti-Semitic graffiti on their home, as well as spreading used oil and placing a dead coyote on their driveway. Prosecutors said during the trial that Fries used similar tactics against another client.
After a search warrant was executed on Friesβ home, authorities found books on revenge that were an βinstruction manual for this case,β prosecutors said.
Fries is already serving a 17-year prison term in federal prison for convictions in 2012 and 2013 of unlawful possession and use of a chemical weapon, providing false information to federal agents and possession of unregistered destructive devices.
His term in state prison will begin after he completes his time in federal prison.
