(tasteofcountry.com) A fan who was critically injured during a stage collapse at the Indiana State Fair in 2011 has undergone successful surgery to replace a portion of her skull that has been missing since the horrifying accident.

Andrea Voss Vellinga of Pendleton, Ind. suffered traumatic brain injury on August 13, 2011, when she went to see her favorite group, Sugarland. Vellinga had special passes to a VIP seating section called the Sugar Pit — right next to the stage — but high winds caused the temporary rigging to implode and fall into the audience. Seven people were killed and 58 others were injured. Vellinga was one of the most critically injured of the survivors, suffering multiple broken bones and skull trauma so severe that she had to be identified by her wedding ring and boots. (More)
