Very interesting documentary, but left me with more questions than answers after watching all 4 programmes. Clearly, the programme was made with a bit of bias, given its focus on the ex-defence lawyer working for Murdoch, but it made a lot of good points, enough to really make the case very questionable indeed without the DNA evidence. And that evidence, also questionable, only the spot on the t-shirt as a cast-iron match, and that's small enough to have been a contact transfer.
I'm generally one who believes strongly in DNA as an indicator, but they sure made a good point that if the incident happened as Lees says, why was there only one tiny speck of DNA on her? Indeed I'd ask, if it happened as she said, why was there not large quantities of DNA of anyone on her? Which only adds to the questions and doubts about her account of the whole thing, having read this thread I know a bit about the no other footprints, the van being moved near her without her hearing, disappearing/species-changing dog, etc etc.
The whole thing leaves me with a lot of doubts about Murdoch's guilt, although equally, it's not impossible that he could've done it, and he certainly is an unpleasant man who was probably well capable of it. I struggle to believe Lees' story, yet I know myself that I'd be terible at recalling things, come across badly, want to avoid the media, give off poor body language, etc etc. I'd be a terrible witness, which means I try to be more understanding of people in her situation... however when no evidence appears to actually corroborate her version of events, it's a bit hard to believe. I have a feeling this is one that'll never be fully solved unless Peter Falconio himself pops up to explain all; after all, there's no evidence that he's actually dead...
