(AP) INDIANAPOLIS - An engineering review has found that stage rigging that collapsed and killed seven people during last summer's Indiana State Fair wasn't built strong enough to meet state building codes.
Scott Nacheman, of engineering firm Thornton Tomasetti, told the state fair commission Thursday that the metal rigging structure didn't meet requirements that it withstand wind gusts of 68 mph.
Nacheman says gusts reached an estimated 59 mph when the rigging collapsed onto fans awaiting a performance by the country duo Sugarland. Dozens of people were also injured in the Aug. 13 collapse.
The state hired Thornton Tomasetti to review the stage structure and Washington-based Witt Associates to investigate the fair's emergency plans and response. Both firms are presenting reports to the fair commission.
