Ohio leads the nation in property insurance claims for the theft of copper and other metals, an industry-supported organization that fights insurance fraud says. The National Insurance Crime Bureau says Ohio property owners made 2,398 such claims during the three-year period from 2009 through 2011. Nationwide, such claims broke the 25,000 mark over the same period, an 81 percent jump from the three-year period from 2006 through 2008. Texas ranked second in the number of metals theft claims, followed by Georgia, California and Illinois.
