It wa Del Rio that told us the shell casings were there, and that LE had no interest in them. I assumed at the time they might have interviewed him at the site, and he saw them. I agree that those casings were important, in that if we are dealing with a hunter that also discovered this blind ( on private property) that they too might have left shell casings behind. As it has been discussed, a good number of hunters pick up their shell casings, but had they left some behind as well it would indicate other people using the blind. I asked Del Rio if he saw any other spent shells during his hunts there, and he did not recall seeing any. That is not to say there weren't any there as shotguns eject spent shells, in some cases quite a ways, that might be overlooked when cleaning up. It is my experience that duck hunters favor a particular type of ammunition, and might have that same brand if you will in their possesion. If a POI had that same ammunition it would certainly curcumstantially tie that person to the site. As a result I would have collected everything. Just my opinion. Has LE ever said anything about shell casings? Or in fact that this was a duckblind?
