Item 2-2.2.1, swabs from the middle of the yellow exercise band
Katarina Stashyn interpreted the yellow-band middle sample as a two-person DNA mixture and reported a likelihood ratio of 1.5 nonillion for Dawson Clancy. She explained that shared family DNA affected the results and that, assuming Dawson was a contributor, Callan and Patrick could not both be present in that mixture.
