to sierra's family or to investigators. they wanted the case to go to trial. they have no doubt this revolutionary piece of dna technology would have put blake russell behind bars for a long, long time. quaal: the nice thing about this is that it will create a picture of this person, and not based on someone's memory, but actually based on the dna in the case, which doesn't change. mancuso: it was everything. it was her fighting and giving us the evidence. it was the coroner swabbing the dna. it was our analyst monica running the dna and staying on it. i'm just very proud that we have people that are dedicated like monica who are willing to challenge new technology. to challenge new technology it's still sometimes unbelievable how awesome technology and scientists and how we were able to solve this
