As the aftermath of the deadliest mass shooting in American history continues to unravel, at least 59 have been confirmed dead and 527 injured following Sunday night’s Las Vegas massacre. From a high floor window of a Las Vegas hotel, a gunman opened fire on an outdoor concert festival on Sunday night (October 1), leading thousands of horrified concertgoers to run for cover.

Country star Jason Aldean was the headliner of Sunday night’s show, which was the final night of the Route 91 Harvest Festival, and it was during his concert when gunfire erupted into the crowd.

It is unclear what caused the gunman, identified as Stephen Paddock, 64, to inflict such a massacre. According to police, Paddock killed himself after firing on concertgoers. According to the Las Vegas Metropolitan Police Department, police found an arsenal in the gunman’s hotel room, including about 23 firearms and about hundreds of rounds of ammunition.

In a statement about Sunday’s mass shooting, organizers of the Route 91 Harvest relayed a similar message that translates with what several famous names shared online: “We will not let hate win over love.”

“On behalf of the entire Route 91 Harvest Family, we are completely devastated by the event that occurred Sunday night. Our deepest sympathies go out to the injured and the deceased and their loved ones. Senseless violence has claimed the souls of our fans and we have little in the way of answers,” reads the statement. “Our eternal gratitude goes out to the LVPD (Las Vegas police department), emergency services, security guards, and fans for their selfless acts of bravery while trying to help those in need.

“While we will try and move forward, we will never forget this day,” the message continues. “We will not let hate win over love. We will not be defeated by senseless violence. We will persevere, and honor the souls that were lost. Because it matters.”
