Acoustic echo which closely follows the original firing pattern with less intensity. This proves that in the absence of evidence people will just make stuff up.

Acoustic echo. That's what I was wondering about.

BUT, at the same time -- does that adequately explain it?

It sure would be nice to be able to access the resort's video monitoring recordings, wouldn't it? To see if there was anyone else who had entered into the same room(s) during the same days the shooter was there. But even then, there would need be capability of verifing there was not a small monkey wrench adjustment made to the recordings themselves (to hide the presence of another shooter, or shooters).

And there we go, in what I just said -- an example one of the kind of doubts that makes way for continuance of conspiracy theories.
