An emergency worker searches a Walmart store that was severely damaged by a tornado in Joplin, Mo., on Monday, May 23, 2011. Fire chief Mitch Randles said about 25 to 30 percent of the city was damaged, and said his own home was among the buildings destroyed as the twister swept through the city of about 50,000 people some 160 miles south of Kansas City."It cut the city in half," Randles said.
