SBM, BBMAs I posted above, that interview is from 1998. I have found nothing about a key hidden outside mentioned in the earlier interviews given in April of 1997.
This interview with PR I find quite interesting, as it underscores how inconsistent they were with so many things. And as is mentioned, that one paragraph of comment from PR is literally nonsensical. In JR's interviews with police and they are discussing his having to break a window to get in the house and more than once, he has never mentioned a hidden key elsewhere. He never mentions Pierre.
...
that's the second time i've noticed where PR, on a fairly important point, gives an answer that sort of dissolves into gibberish. the other one being her nonsense non-answer about the cell phones. do people think that's a deliberate tactic? say something that feels like an answer to people who aren't paying close attention, but essentially just muddying the waters for people who are?
at any rate, claiming they had a spare key hidden outside that was now missing is an untestable theory that conveniently creates reasonable doubt out of thin air. ... IF we believe her. and with no prior mention of this key in earlier statements to police, i don't believe her.
