OMG, waaaaay back when this case was fresh I was absolutely convinced Drew had somehow had Stacey cremated. My way of thinking then was that he couldn't have made a bonfire and burned her up (but...might get noticed/ caught with a fire) then I googled and found out it takes a very high temp for a body to be cremated and reduced to ashes. It COULD be done as a bonfire but it would have to be an intensely hot fire, would take hours and hours, etc. I even went so far as to call a funeral director I knew and asked what the chances were that a cop could talk someone into cremating a body in their crematorium, say if he had info on a funeral director he could use against him and blackmailed him into burning Stacey's body "off the books", so to speak. He said its highly regulated and not likely but not impossible.
So its still niggling there in the back of my mind, if he had a 'professional' cremate her to get rid of her body.
Who knows? I am pretty sure DP will NEVER tell what he did with Stacey's body, even if he gets 60 years for killing Kathleen.
