Thanks to all for bringing this interesting information back to the forefront.
I was absolutely chilled to look at the DCasey search video again; even after all this time has passed, the effect has not lessened.
LolaMoon08, thank you very much for the list of time markers in the vid and a focus on specific materials such as pavers and fabric. That is very useful information and I've bookmarked your post as a "keeper."
Many have raised several interesting points about why DCasey did not do anything further (if he did indeed find the remains, which I tend to believe). All of them sound plausible. And yes, it is very interesting that the video seems cut/redacted....
One thing that crossed my mind as I was reading ANewsJunkie's timeline post was this claim by Todd Macaluso:
"Substantial evidence" sounds like "material evidence" to me. And yet Baez was (is) still following the TES search angle:

I am getting mixed signals/conflicting info here and really going out on a limb with some speculation.

But here goes: Information from DCasey may have been crucial to two key Defense alternative narratives.
Story 1. The remains were there. But, with some fudging and "creative imagining," the timeline could be muddled so as to exculpate their client. Perhaps Macaluso was working this angle? Again, a huge speculation on my part.
or, possibly:
Story 2. The remains were not there. DCasey, agreeable chap that he is, could insist that he did not find anything at all. Perhaps Baez was working on this angle, which could possibly be buttressed by what he deems to be an insufficiency on TES's part.
There are some tantalizing loose ends, though, as others have pointed out upthread. State has listed DCasey as a witness (what a story he might tell!). Defense has not deposed DCasey. The latter is very interesting indeed. jmo
This Macaluso stuff has me really stymied. Of course, he could have been just spinning his theories (like me lol). But "substantial evidence"? Just thinking aloud, as it were. Carry on!
Now, back to DCasey....
