Almost a year after a tornado leveled large portions of Joplin, Missouri, new footage from a hospital security camera shows the devastation as it occurred.
St. John's Medical Center was among the most heavily damaged buildings in Joplin. Winds of 200 miles per hour ravaged the interior. The footage shows chairs and tables swept up and tossed against the ceiling and walls. No people appear in the 36 seconds of video.
