Oh, picky, picky
My guess is that if a DNA match were found in known contacts, the DA wouldn't rule it out as innocent contact, because of the circumstances in which the DNA was found.
Well, with this DA, that wouldn't shock me. Seems to me you're putting an awful lot of faith in someone who let herself get snowed by Michael Tracey! Children are messy, filthy little things who need a lot of supervision. That DNA was found in areas that, due to JonBenet's unique circumstances, any number of things might account for, it's hardly conclusive.
Matching DNA under JBR's fingernails and in her underwear is pretty dam^ed incriminating circumstances for a rape homicide, doncha think?
If this were a rape-homicide, I'd be the first to agree with you, Holdon.
