We're all pretty familiar with the term "multi-tasking".....but this is not a good example. 26 year old Benjamin Christensen, of Belmont Street, Carbondale set buildings on fire...then battled the flames as a volunteer fire fighter. He was sentenced in Lackawanna County court to ten to 20 years. The fires caused millions of dollars of damage and included the Fiorelli Plaza blaze on Main Street in Peckville in March of last year. A fellow volunteer suffered a heart attack fighting that one. Christensen's co-defendant, Robert Woolaver is doing 4 to 16 in a state slammer.
