I agree that what has already happened, has happened- except for my own clarification and analysis of course, which I am admittedly OCD about, lol. The more people that understand the challenges facing SAR dogs and handlers and LE, the better.
My other thought is that it is
not necessarily a moot point at this point, actually. The blood found at the scene is cadaveric scent.
It's certainly been awhile... but a properly trained HRD K9 could scent off of that. Arduous, but possible. If Holly had an injury, wound or any other scent DNA evidence at the site- and was not Kimstered from the site where she was last seen... seems like we might have a new option to work with. Kwim?
