Imagine that. The people who knew him best, who knew what types of areas he would like, who probably told LE exactly where to look, who were the first into the area after the water receded, were the people to find the articles. How could that be possible. ahh, I see, they have been keeping his stuff hidden in the raised garden box out back to get it weathered and then mailed it to an accomplice to hide in the swamp, so they can then, dah dah dah, find his dead body. I don't see the risk of prison being enough to do that.
So what dastardly scheme are you proposing that fits your skepticism?
