What I am puzzled about is why Denise and Brian continue to live in the same house as Denise and Mike did. With the whole town talking about them for 10 years, one would have thought they would have moved by now. Given that Denise had so much insurance money paid out, why didn’t she move anyway. Most people getting $1.5million would buy a bigger, better house. There has to be a very good reason why she is staying where she is and the only reason I can think of is that there is some evidence at that house that Denise does not want anyone to find. A new purchaser may go digging in the wrong place and find something they didn’t expect. There doesn’t seem to be any evidence that Mike left the house that morning; maybe he didn’t. Could Mrs Williams get a warrant for a search? Is it possible to check for seismic activity from all that time ago? Why else would someone with that much money stay in a place where so many are talking behind her back? it doesn’t make sense to me.
