That shaggy-haired couple would have to be a lot more than anonymous. There was not s single hair or fiber or print that came from ANYONE outside the family. The DNA? Well, the DNA from her fingernails has to be completely discounted because of the fact that the nail clippers the coroner used were not sterile, not used properly, and may have also been used on other bodies. That DNA found there may have belonged to the poor old man in the next drawer over.
The DNA in her panties has been referred to as the donor's BLOOD. It was not. It was DNA found on the crotch of the panties (along with fibers from JR's wool shirt) in the area where JBR's blood was also found. This, along with the "new" touch DNA from the waistband of the longjohns, may have been put there in a way that had nothing to do with the crime. It was skin cells. If JBR, or someone who handled her clothing that night (both parents have stated they did so) touched something also touched by the donor, then that would be a way for the skin cells to transfer to the clothing. The DA's office has allowed the misconception that "unknown male DNA" means ADULT male DNA. It does not. DNA cannot tell the age of the donor, with the exception of certain things like semen, where the donor would have to be over the age of puberty by the nature of the sample. That DNA could have come from any of the male children at the White's that day, as well as any male child at the R home that day (The Rs have admitted that their son had friends over Christmas Day). Those children, now grown, have to be tested to be excluded as the donor as well, and this doesn't mean they were the KILLER. That's why Lacy's statement was so harmful to this case.
