A plaque honoring those killed was unveiled during a small, solemn ceremony near the grandstands Thursday morning, RTV6's Derrik Thomas reported.

Special Section: Indiana State Fair Stage Collapse

"In memory of those lost on Aug. 13, 2011 … may the Hoosier spirit continue to reside in all of us," the plaque reads.

It also lists the names of those killed -- Alina BigJohny, 23; Nathan Byrd, 51; Glenn Goodrich, 49; Jenny Haskell, 22; Christina Santiago, 29; Meagan Toothman, 24; and Tammy VanDam, 42.

Andrea Vellinga, who suffered serious head injuries in the collapse, attended Thursday's dedication.

"I think it was a great way to honor everyone who passed away at the concert we were at," she said.

But BigJohny's family was upset at how the ceremony was handled, saying the member of the State Fair Commission were late and didn't speak with the victims' families.

"The only word that comes to my mind is 'disrespectful.' I just don't feel like they are trying to understand or have any compassion," said BigJohny's sister, Christy Collins. "If you knew my sister and how much she meant to our family and her friends and how many lives she touched, to see her name on a little plaque in front of that is not justice for anything."

BigJohny’s mother, Polly BigJohny, said more could be done to honor the victims.

"I think it's pathetic. It’s not enough for any of the victims,” she said.

State Fair spokesman Andy Klotz said the plaque was respectfully created to honor the victims’ lives.

"The plaque is something we think is respectful and consistent with other things we've done at other places here at the fairgrounds where we’ve had unfortunate incidents. We think this is something that will help people pay their respect,” Klotz said.

Seven people were killed and more than 40 were injured when rigging above the grandstands stage collapsed onto the crowd awaiting a performance by Sugarland.

On Thursday, the Indiana State Fair Commission approved a new emergency management plan based on recommendations from emergency management consultant Witt and Associates.

The plan calls for the fair’s chief operations officer to decide whether to postpone or cancel events during an emergency.
