What would happen to a body, tied to an anchor, dropped over the Mariana Trench?

With all this talk of James Cameron visiting the bottom of the Mariana Trench, I got to thinking, what happens to sailors, who drown, and end up sinking to the bottom of the ocean? 

First, do their bodies actually sink? Or do they just float on the surface? 

Second, if they do sink (let's tie them to a small anchor, just in case), do they just keep going until they hit the ocean floor? Or is it that the water eventually becomes so dense that at some point they stop and become suspended?

The density of water actually would hardly change at all no matter how deep you go since water is nearly incompressible.  With a weight the body would sink right to the bottom, but it would not be crushed in any visible way since there aren't many air pockets in a body.  It will just rest on the bottom, decomposing incredibly slowly, as things do at the depth.  Primarily it would be eaten by scavengers.
