once again, joanne chambers blood dna matched the dna from the stamps and the envelope flap. >> you could see how all five genetic markers line up perfectly between the dna of joanne chambers and the dna from the back of the postage stamps. >> the odds of someone in the random u.s. population having the same combination of five genotypes tested was 1 in 14,925. >> the match was fairly significant in that that's a small community there, so it's unlikely that too many people are going to be walking around with a similar dna pattern. >> despite the second dna test, the prosecution refused once again to drop their case against paula nawrocki. during the trial, the prosecution presented the circumstantial evidence against paula nawrocki, including the
