Hotel Pool Ceiling Collapse - York, Nebraska
Hotel Pool Ceiling Collapse - York, Nebraska
(OP)
Looks like this one didn't get mentioned. One of those pictures looks alarmingly like the 2x4 ceiling was glued to a concrete floor above. In a natatorium? Yikes. Resulted in the death of a 10 year old boy.

As the article states, nobody knows who is supposed to conduct the investigation on why this happened. You see that often in smaller communities. They barely have enough staff to review plans and issue building permits, but never enough to make sure the old buildings are still safe to occupy.
RE: Hotel Pool Ceiling Collapse - York, Nebraska
I DO hope the potential crime scene was closed up.
The possible crime could have been in attaching the dropped ceiling to the concrete in a thoroughly and notably improper manner. If that "method" was easy enough to see, the building inspector could also be charged.
There was a death due to a construction failure, and I'm not sure that "It was an accident." should be as far as it goes.

A quick Google search says that the statute of limitations would be less than 7 years. And the hotel opened...12 years ago? So there's unlikely to be a criminal case. May not be a civil case against the design team, either. Against the hotel for failing to maintain the structure...that might have teeth.
RE: Hotel Pool Ceiling Collapse - York, Nebraska
Good point on the statute of limitations. In Nebraska, it's 3 years for manslaughter.
However:
"Generally, the statute of limitations starts when the crime occurs. But in circumstances where it's difficult to discover the crime or a victim might be particularly scared to report it, the law might delay the starting of the time clock or extend the limitations period."
It's certainly difficult to discover the crime if the ceiling is still glued up and the kid is alive. As in 3 years ago. This could argue for a much more recent start date.
"Against the hotel for failing to maintain the structure..."
Was there any evidence that the ceiling needed maintenance?
Did the builder leave maintenance instructions with the owner that the owner did not follow?
Are there any well known maintenance demands for a sheet rock ceiling?
I DO appreciate that the problem could be a damp environment, as you noted.
At the VERY least, the State contractor's board should be down there to investigate whether the contractor should lose his license.
Around here, we had the (in)famous Berkeley balcony collapse, where several people died. There WAS a criminal investigation for that one.

favorfamily (sorry - typed the original on my phone) and suggest theyforfile a complaint with the engineering board. Might shake something loose...RE: Hotel Pool Ceiling Collapse - York, Nebraska
With the Berkeley collapse that I mentioned above, it appears that the only thing that got a real investigation started was the continuing pressure from the families of the dead people. They (rightfully) raised hell about it. When I wanted information on what happened over at the site, I found that the Irish papers had better coverage than here (they were mostly visiting Irish students).
I recommend the parents friends and family of the kid do the same, and not give up. "Easy for me to say" (I just said it), but I think it would get results IF they're in the mood. I hope they are.

Here's a picture showing our set-up next to the hotel prior to the start of the event:

And just for interest, here's a better shot of my camera set-ups:

And for anyone who's never experienced a total solar eclipse, this is what it looked like during the period of totality:

And while I'm at it, here's one of the better shots I got of the eclipse itself (note that there was a bit of overcast that day, but it was still an amazing experience):

Probably worth noting that it's not just a damp environment that's a problem. There are glues for that. Some decent ones available at home depot (though I wouldn't want to hold up a ceiling with them, even in a dry environment).
A natatorium is an incredibly corrosive environment. It may not reach a level to harm your health (though some do - some pools make my eyes burn just looking at them), but there's still chlorine in the air. It attacks everything. There have been a few pool roof failures over the years as well as major repairs done because the engineers involved didn't understand the environment that was going to be placed inside the structure. It's pervasive and will cause corrosion in things we typically consider immune to corrosion. Here's an article that looks at varying levels of service for stainless steels in and around pools.

These form when the Cl reacts with organics (mostly skin cells and urine).
Those of us that work with SS are forever concerned about chloride stress corrosion cracking.
In a normal Cl environment (rural coastal) there is a fairly reliable threshold temperature for CSCC.
In chloramines the temperature requirement drop from ~150F to 80F.
With plain steels the big risk is that they start to corrode and then the hydrogen from the corrosion causes cracking.

Mayybbeeeee.
Looking at the "after" picture:
I can see spots of "glue" on the upper surface of a lot of the sheetrock. This implies that SOME of the sheetrock was glued directly to the concrete ceiling.
I also see wood framing BELOW that sheetrock. That is, from the top, we have concrete, sheetrock, framing, more sheetrock.
I believe this room had a full sheetrock ceiling glued up to the concrete--wall to wall. Then the soffits were built underneath.
I see a lot of "nails" protruding from a 2x4 over on the middle left. I believe that 2x4, and others, was "nailed" up onto the sheetrock/concrete ceiling, further framing was installed to define the soffit, and then sheetrocked itself.
What those "nails" were is of interest. They clearly pulled out.
And the glue didn't do much to keep the top layer of sheetrock on the concrete, did it?
It does not appear that there were any hangers cast into the concrete.
It's quite possible that the soffit was an afterthought.
