The Indiana State Fair Commission last week appointed consultant Thornton Tomasetti to investigate the Indiana State Fair stage collapse that killed six people and injured dozens more.
The consultant previously investigated the 2007 collapse of the I35-W bridge in Minnesota, which killed 13 people. The firm will look into the events that triggered the accident on 13 August. A sixth person died on Friday from injuries sustained in the accident, according to reports.
Officials and the organiser of the fair have said that the collapse was caused by a “freak” gust of wind, which it could not have prepared for.
