After a raging fire consumed four blocks of boardwalk previously spared by Hurricane Sandy on the Jersey shore, local investigators are asking the public for any photographs taken before or immediately after the blaze. On Friday morning, Gov. Chris Christie told press the investigation would take days, but he would not speculate on the what sparked the fire, which is thought to have destroyed at least 30 businesses in the popular tourist area. Initial reports point to a Kohrs' ice cream shop. "Our hearts are broken," the owners said in a statement.
