Four spectators were killed and 40 people were injured after a strong wind struck an outdoor concert stage last August 13,2011 at Indian State Fair, few minutes before country music duo Sugarland was set to perform.
An amateur video from witnesses is enough to describe how strong the wind was and how it devastated the stage where thousands of people were ready to hype up.
Sugarland sent a twitter message, saying " We are all right. We are praying for our fans,and the people of Indianapolis. We hope you'll join us. They need your strength."
After the incident, rescuers and some other folks helped each other to rush the injured ones and finally they have discovered four casualties.
