Reuters reports that Guyard-Guillot, 31, fell during the final scene in which performers engage in a battle approximately 70-feet high while wearing safety harnesses attached to a cable. "I am heartbroken," said Cirque du Soleil founder Guy Laliberté in a statement. "I wish to extend my sincerest sympathies to the family. We are all completely devastated with this news. Sassoon was an artist with the original cast of KÀ since 2006 and has been an integral part of our Cirque du Soleil tight family. We are reminded, with great humility and respect, how extraordinary our artists are each and every night. Our focus now is to support each other as a family."

A statement on the company's Facebook page reads, "Our thoughts are with her family and the entire Cirque du Soleil family." The company is currently working with the appropriate authorities and is offering full cooperation.

Guyard-Guillot also taught at a school called Cirquefit, a Las Vegas program for children. Donations are being accepted for "the children's future" and can be made at ForSasoun.com.
