The deadliest mass shooting in modern U.S. history left at least 59 dead and more than 520 people injured after a gunman opened fire on crowd of 22,000 concertgoers during a country music festival on the Las Vegas Strip.

A post on Klymchuk's Facebook page says she got engaged in April, and was in Vegas with her fiancé.

"Susan was wonderful with the kids and the staff and was an integral part of the school community here," said Jake Finch, the public information officer for the district. "She was the hub of everything that happened at the school. If a kid is sick, she's the one calling the parents and no matter how chaotic things got here, she was always smiling."
