I think they keep regular business hours but I wouldn't be surprised if the autopsy was being done this weekend--the thing I am unsure of relates to how much of the results will be made public--not sure who makes the decision on this.
I don't know who makes that call either, Helplessly....but maybe someone on this board will.
I just hope Shane's family gets any answers they need. Sadly, I know answers still won't bring their beloved son back, but hopefully they will get them.
