CHARLESTON, W.Va. -- The multi-platinum selling duo Sugarland is in Charleston to give depositions about last year's Indiana State Fair stage collapse that killed seven and injured dozens.

On Aug. 13, 2011, a wind gust estimated at 60 to 70 miles per hour toppled the roof and the metal scaffolding holding lights and other equipment. The stage collapsed onto a crowd of concertgoers awaiting a show by the country group.

Lawsuits have been filed against Sugarland, the fair and companies involved with building the stage.

Band members Jennifer Nettles and Kristian Bush were in Charleston Thursday and Friday to give court-ordered depositions.

Ann Keil, a reporter with Fox 59 News in Indianapolis, said the band stopped in Charleston en route to their next tour date in Pikeville, Ky., where they will perform Friday.

Keil and other Indianapolis news trucks parked along Summers Street outside the Summit Conference Center waiting for Nettles to arrive. Her deposition was scheduled for 3 p.m. Thursday. Bush will be deposed at 9 a.m. Friday.

Dozens of attorneys entered the conference center, some representing family members of the victims and others representing production companies. Nettles slipped in the back of the building, not giving reporters a chance to ask questions.

Keil said she made the more than 5-hour drive Wednesday and would stay the night again in Charleston on Thursday.

"A top state fair official claims the band twice refused to cancel the show even though they were warned about bad weather," Keil said. "They're being sued to discover who's responsible and to what degree."

Also Tuesday, an engineering report was released stating the stage that collapsed wasn't built strong enough to meet state building codes, according to The Associated Press.
