TUCSON, Ariz. -- A Tucson man already serving a 12-year sentence for using a chemical weapon on a dissatisfied customer of his power-washing business has been sentenced to more prison time.
Federal prosecutors say 50-year-old Todd Russell Fries has been sentenced to a 60-month prison term, with 20 months to be served consecutive with his previous 151-month sentence.
A federal jury in August found Fries guilty on two counts of possession of unregistered explosive devices.
Agents served a search warrant at Fries' home in 2011 and found 24 explosive devices in a bedroom.
Fries was convicted in October 2012 of the chemical weapons charges, which stemmed from a 2009 incident.
He was accused of placing a chlorine chemical device at the home of a former client with whom he had a billing dispute.
