So sorry coyotebc, sounds like they had all been trying to do the right thing to manage a safe night. I figure it's going to be a long, hard, intense few weeks of woulda/coulda/shoulda's...

Best I can say is they don't have to try and figure this out/go through this alone...nothing wrong with getting some support from folks who deal with tragic events like this on a regular basis...they can help them through it and make some sense of this disaster...

Many thought and prayers to you and yours...
