An Eastern Iowa man has pleaded guilty in federal court to mail fraud and using fire to commit a felony. Federal prosecutors say James Marvin Plower of Olin faces at least 10 years in prison and up to 30 years. At a plea hearing Friday in federal court in Cedar Rapids Plower said he made up a scheme to defraud his insurance company. He set fire to his home in Martelle and submitted an insurance claim asserting the fire was accidental. He collected more than $66,000 from the insurance company.
