A massive tornado tore through Joplin, Missouri, killing at least 89 people and carving a mile-wide path of destruction through the city. The Joplin tornado hit at around on May 22, destroyed at least 2,000 homes and businesses. The death toll is expected to rise as rescue and cleanup efforts continue. [Update: the Joplin tornado death toll has risen to 116 so far.]
St. John's Regional Medical Center, the main hospital in the region, was hit directly by the tornado; its roof was torn off and all of its windows were smashed. Missouri Governor Jay Nixon has declared a state of emergency, and FEMA is sending an emergency management team to Joplin.
