I took some days off from the case and
@Tortoise 's excellent wedding dress box post was what stayed into my mind
For a long time I have believed Chase is sock puppeting the case via his counsel. So if you want to know what really happened, you just need to look at what is sensitive to Chase.
The graveside knife & rape. The wedding dress box. The 19K. Chick-Fil-A etc etc etc
These are all artefacts of the real crime.
This is poor man's Barry Roux + Oscar Show
In any crime, there are a certain number of mistakes made by the prosecution and especially by the witnesses. The puppet master seeks to reconstruct his defence in these areas of uncertainty. So our dear friend Oscar P nearly skated for murder because of an honest mistake whereby multiple witnesses confused cricket bat bangs with gun shots. Everything flowed from it, to the point that direct line of site witnesses were told that the women they heard screaming for many minutes was in fact poor Oscar.
This case is the same, except the first iterations are much clearer to us. Back when Summer was a nasty piece of work and it wasn't Joey in the border crossing video. But of course we can't pretend it was Summer anymore. So now Dan is the proxy.
Chase never has any agency in all this. He variously never answers the last call, which he also never remembers. He doesn't remember if/why would he be driving at 9.30pm. The invisible man.
Fascinating stuff.
