Sugarland Concert Stage Collapse Leaves at Least Four Dead (Video)

High winds caused the tragic accident at the Indiana State Fair.

A massive gust of wind turned a festive concert at the Indiana State Fair into a tragic event on Saturday night. At least four people died and dozens were injured when a strong wind blew through the concert venue just before Sugarland was to take the stage.

Winds on Saturday night were estimated between winds between 60 and 70 mph.

The Indianapolis Department of Public Safety posted on its Twitter page the death toll and wrote that 40 people had been taken to hospitals in the area. An unknown number are in critical condition.
