First responders radio in that they are at the end of a hallway on the 32nd floor but are cautious to avoid fire from other first responders.
\"We are going to be peeking out into the hallway. Those officers down the hallway are going to need to acknowledge so we don't have a crossfire,\" one says.
11:20 p.m.
Police dispatch recordings hear first responders breach suite 135 on the 32nd floor of the Mandalay Bay hotel.

\"Tonight has been beyond horrific. I still dont know what to say but wanted to let everyone know that Me and my Crew are safe. My Thoughts and prayers go out to everyone involved tonight. It hurts my heart that this would happen to anyone who was just coming out to enjoy what should have been a fun night. #heartbroken #stopthehate,\" he writes.
