Joplin's St. John's Regional Medical Center is the only building still standing for miles in the tornado-ravaged city. Sunday's tornado claimed the lives of five of the 183 patients there.

CNN's Ali Velshi talks to Gary Pulsipher, CEO of the Center, and Dr. Sean Smith, Emergency Room Technician.

Ella Smith and her husband sought refuge in the basement of their Joplin home when the tornado was bound to hit. Their home was destroyed and collapsed ontop of them; the two were pulled out from under the rubble and survived.
