I agree 100% Lovely but what the source of the dna the only thing I can think of would be saliva. The problem is BDD wont release the dna reports and even then they can't identify the source of the dna.
Which brings us to how do we know the dna under her fingernails match or is consistant with the dna in her panties and what about the hair it was a pubic hair right it could be dna tested to see if it's consistant with any of the other samples.
