I cant find the audio at the moment - but I swear - at least one version of the “Engineer’s” call - you can hear the person they are talking to - and they seem aware of the situation - and says something like “he’s on 32” - as if they are talking to someone else.
I think the MB staff knew exactly where the shooter was, and therefor who it likely was. I am not seeing where that information was passed on to the LVMPD.
It seems LE went to the scene without that valuable information and from scanner transcript I don’t see when they were actually given the information.
