A stage collapsed during a powerful storm at the Indiana State Fair, sending steel scaffolding into the terrified crowd below and killing at least four people among fans awaiting a performance by the country band Sugarland. The collapse Saturday evening happened moments after an announcer warned of the advancing storm and gave instructions on what to do in event of an evacuation. Witnesses said a wall of dirt, dust and rain blew up quickly like a dust bowl and a burst of high wind toppled the rigging. People ran amid screams and shouts, desperate to get out of the way.Hundreds of concert-goers rushed afterward amid the chaos to tend to the injured, many with upraised arms seeking to lift heavy beams, lights and other equipment that blew down onto the crowd.
