There is a new technology DNA testing that is to do with pubic hair. Apparently the main problem in the past has been that in most cases the perpetrators pubic hair didn't have roots as it was 'shedding' hair and partly degraded.
One element that doesn't degrade is bacteria.
Females have on average 76 sorts of bacteria and males 73.
The bacteria mix is like a microbial fingerprint maybe this is how Hart got nicked and KK and CG got linked.
Another reason for pursuing this line of research is that perpetrators have been outwitting police by being more forensically aware wearing condoms and taking them away to dispose of else wear etc.
Thank you so much for this information.
My first instinct is to think that they subsequently found pubic hairs on CG they were able to test. However, if they had a solid DNA profile from KK from the beginning I would assume that any DNA they got from CG or JR at the beginning would match that. So maybe they only got pubic hairs (or something else that couldn't be tested comprehensively at the time/something with different forensic information) from KK as well and that wasn't tested until later.
However, I still wonder then how familial DNA and a subsequent direct test on BRE would link to everything. Unless it's a case of "A links to B which links to C which links to D".
