Barmaid ...
Knoxy's DNA was all over the house ... but not in Meredith's bedroom.
Meredith evidently valued her own space, and Amanda respected that.
The bra clasp ...
After six weeks (!) of investigation, the prosecution had found none of Amanda's DNA in Meredith's bedroom ... none ... nada ... not a single, teeny bit.
There was only one possible conclusion ... Amanda had never been at the scene of the crime.
But Gulio Mignini wasn't having any of that. He was srong, but he wasn't going to admit it.
So they went back, and found the bra clasp, which had been kicking around on the floor of the flat for over six weeks, hoovering up all sorts of mixed DNA ... several different people!
It was bagged by an officer who admitted he had (1) handles items belonging to Amanda, and (2) failed to wear gloves to collect the bra clasp.
There was ALL SORTS of DNA on there. Evidentially, it proved nothing whatsoever.
But it didn't need to.
Amanda's lack of presence was already thoroughly proven.
But ... Mignini's so-called "DNA expert" supposedly managed to find a bit of Amanda'a DNA (or was it Raf's?) from among the assorted DNAs on the bra clasp.
The prosecution claimed this proved their case.
The Appeal judges have confirmed that it did no such thing.
