Disneyland employee Carrie Barnette has been identified as one of the 59 killed in the Las Vegas shooting on Sunday night, Disney CEO Bob Iger confirmed in a statement on Monday evening.

Jessica Milam, another Disney employee, was also injured in the attack, the statement added.

“Our hearts go out to everyone impacted by the tragic events in Las Vegas – the victims of violence, the witnesses, and the friends and families mourning loved ones,” reads the statement. “We are especially heartbroken over the loss of one of our own to this unconscionable and senseless act. Carrie Barnette had been a member of the Disney California Adventure culinary team for ten years and was beloved by her friends and colleagues. Our thoughts are with her family, along with our support, during this incredibly difficult time. Another valued Disney cast member, Jessica Milam, was also seriously injured and we are praying for her recovery.”

More than 500 people were injured when a gunman opened fire on attendees of the Route 91 Harvest Music Festival near the Mandalay Bay Hotel and Casino in Las Vegas on Sunday night. The gunman, Stephen Paddock, was found dead in his hotel room.

Given the number of victims killed, the shooting is the deadliest in modern U.S. history.
