The Cirque du Soleil family is mourning the tragic loss of one its own. After an accident during a Saturday, June 29 performance of Ka at the MGM Grand Las Vegas, acrobatic performer Sarah Guyard-Guillot died at age 31. The Paris-born performer was one of the acrobats suspended by a wire during the show's "Final Battle" scene; she somehow slipped from her safety wire and plummeted about 50 feet to the pit below.

"(The artist) was being hoisted up the side of the stage and then just plummeted down," eyewitness Dan Mosqueda, told the Las Vegas Sun. "Initially, a lot of people in the audience thought it was part of the choreographed fight. But you could hear screaming, then groaning, and we could hear a female artist crying from the stage."

Reportedly the first death in the 30-year-history of the worldwide Cirque du Soleil performance franchise, Guyard-Guillot was pronounced dead at 11:43 p.m. Saturday at University Medical Center.
