We won’t find one single point of failure,
~~~~~~~~~~~~~~~~~~~~~~~~~
The video of the collapse indicates that the center section closest to the pool dropped first... but the rest of the building dropped straight down almost immediately after. Then about 10 seconds later, the ocean side section went down and it followed the same pattern of the south (pool) side dropping first to be followed almost immediately by the rest of the building....so that in both cases, both sections essentially came straight down. What that tells me is that the entire support structure was weak as stink but in all cases of failures, something goes first and in this case, it was the support structure closest to the pool that let loose first. Since the rest was already weak (overloaded) the transfer of load put it over the top and down it came.
I agree with everything except that the pool is in the sw corner. The only thing left standing is the entire west side and the tip that turns south. The entire north and east side is gone. Furthest from the pool
I found this. It shows north and west sides. You can see parking entances.

Yup, and according to the PE's report, that area near the pool appears to have had the most structural damage that, if wasn't fixed soon, would "cause the extent of concrete deterioration to expand exponentially"
It looked that way to me as well, and once a progressive collapse is in motion, it’s well, progressive.
But the forensics will evaluate everything, including the video evidence, and there’s plenty of concrete and rebar on site to test and evaluate. This will be the topic of discussion and study at ACI, ASCE, ICC etc. for quite a few years.
