sarx, thank you for joining us!
So it sounds like the cadaver dogs alerting at the boat ramp just indicates a likelihood of a deceased person there at some point, with no real indicators of how long ago it might have happened (and no indication of the identity, of course, based on your #1 response).
I imagine that lingering scents can really confound an investigation at times. This scent could be from someone months or even years ago, right?
Honestly, a single point is not generally a body dumping ground, though anything is possible, and there have been cases where a dog has alerted on a search and it ended up being a different victim than who they were looking for, but it's not all that common.
What the dog is trained on in terms of water scenting would give answers/clues as to whether it was fresh or old. And of course, there is always the chance of a false alert. I can only call a dog's alert 100% accurate if a find happens because of their work.
