A recording of dispatch radio calls shows that emergency workers were expressing concern about severe weather just minutes before winds ripped through the Indiana State Fair and caused a fatal stage collapse.
WTHR-TV in Indianapolis obtained recordings of Marion County dispatch communications from the night of Aug. 13, when thousands of fans were waiting to see a concert by country music group Sugarland.
In one excerpt, workers are warned about five minutes before the collapse that severe weather was moving in and advises them to seek shelter if necessary. Two minutes later, another dispatcher asks if concert fans have been released from the grandstands.
Fair officials have said they were preparing to order an evacuation when the stage rigging collapsed into the grandstands. Seven people died.
