Not really.
It could mean that Brenda had been in there -- which opens up all kinds of possibilities. Or, maybe it was the boys.
And then there's the "when?' part of that to ponder.
Corrupted / planted evidence? We wouldn't tend to assume that sort of thing, but why wasn't the hand-print found on the first visit? Other things, as well.
The entire sequence of events strikes me as very odd. I'm not inclined toward being "conspiratorial". For example, I never did believe that JFK shot Martin Luther King.
Still, there are a quite a few things in the evidence that seem "off". Maybe someday someone will make a list. It includes just about everything. There is very little that seems solid or to stand too well on its own, even without a close look.
ALREADY BEEN DONE. The website is called STEALTH NINJA DAVE !.
Jaded created and hosts the website and has all the evidence listed, and tons of other stuff.
WARNING! If you go there, you might learn more than you ever knew possible!
HELP JADED, I can't find the link to post for HARRY to use to get to your SITE !!!!!
