Authorities say a deadly tornado that wreaked havoc in the small city of Greenfield, Iowa, left four people dead and nearly three dozen injured, while a fifth person was killed elsewhere. The twister that tore through the city on Tuesday was rated at least an EF-3 by the National Weather Service and was so destructive that it took authorities more than a day to account for the area’s residents. Officials believe the number of people injured is likely higher. The deadly twister was spawned during a historic tornado season in the U.S. April had the second-highest number of tornadoes on record in the country.
