Stage rigging collapsed after a storm gust Saturday night, trapping at least a dozen and killing five people during a concert at the Indiana State Fair.

The outdoor stage was set up for the Sugarland concert.

Dave Lindquist, music journalist for The Indianapolis Star, reported on Twitter, “Tragedy at fair concert. Entire stage collapses on track.” He also wrote that “perhaps a dozen injured people have been removed from track on stretcher-type boards.”

Concertgoer Amy Weathers told Lindquist, “It was like in slow motion, you couldn’t believe it was actually happening,” he tweeted.

The lead singer for the country band Sugarland says members are heartbroken.

Nettles has issued a statement saying the band is “stunned and heartbroken for the fans and their families in Indiana. We hold those injured in our prayers at this very sad time. There are no words. It is tragic.”

Luckily, Sugarland wasn’t on stage when it collapsed.
