I hope they have kept an eye on that spot ever since Zerilii's statements became public, as to make sure the remains wouldn't be moved, in case it's there...
I bet the Feds have been watching it. It would be funny for them to bust some 75 year old out there with a shovel and a partially dug hole(s). If I were on surveillance and I saw someone head out there with a shovel, I would let them dig a while before I made a move. I hate digging holes.
I have heard that guys used to plant a tree on top of their corpse hole. That way in 5-10 years there is an established root system obfuscating corpse recovery.
