police officers heading towards the bellagio. they're all going from the mandalay bay right now literally passing tropicana heading towards the bellagio where they just had more reports of an active shooter. >> and what's your sense with the shots that you witnessed, where did you think those shots came from? did you feel they came from high up, another floor, many floors above you? >> i mean, in vegas, all the concrete and the echoes, i can't really tell. it took me a minute to even realize they were shots. i mean, you're just not used to hearing that. >> yeah, and brian, give us a sense for people that don't know las vegas where is the bellagio in relation to mandalay bay? are they in close vicinity of each other? >> i would say within a half a mile. the blocks seem a lot larger here.
