We know that without the swift and brave actions of first responders the scale of damage would have been much greater. We know that in the midst of chaos and fear people acted to protect and save others – those they knew and those they did not.
In the coming days, we will hear more of these stories as we grieve for the victims of this unspeakable tragedy.
We’re working with law enforcement in every way possible. At the moment, we are deferring communications about the investigation to the FBI and Las Vegas Metro PD.
Please pray for all the victims of this horrific event, our Las Vegas community, and all our employees who are working tirelessly to provide support at a very difficult time."
