Was some closer and some distant? That’s what some are hearing. But the person is traveling in the car and the perp was firing from two sides.
Other thing is the flashing light some believe is muzzle fire on the 4th floor.
I think some were echos. And if he went from window to window it would change the sound.
It sure sounded like an M-60 though. But now we know it probably wasn’t an M-60. We’ll never know for sure.
There sure are a lot of pieces to put together.
As far as I can tell from the photos there do not seem to be any windows broken out below the floor from which the wingnut was shooting. That would indicate to me that there was no second shooter from Mandalay Bay.
