I find it hard to believe that he hasn't either confided in someone or slipped implicating himself (he slipped in an early interview by speaking of Tracey in the past tense before her car was even found). I think we're dealing with a sociopath - one that has gotten away with this for as long as he has by pure luck alone (definitely not intelligence). There are some that don't believe he's capable (denial) of such a thing - he's apparently very good at hiding his ugliness. We haven't had a search in a while (Sept) - but will probably be back out there as soon as we can all get together and pinpoint an area of interest. We have bits and pieces to go on, but it should be enough to target a specific area as we've done in the past. We're determined to see him .... LE is aware of the keys .. they know what the deal is, it's just a matter of getting the evidence that they need to make a solid case one that will hold up in court - don't want the case to fall apart b/c he can only be tried once.
