Brief Quote / Description of Testimony

The victim was a B secretor and Dominguez was an O secretor. Two stains had B and H antigens, consistent with the victim. The analyst testified that Dominquez could not be eliminated and that type O secretors are 36 percent of the population. Due to masking, none in the population could be eliminated. For another stain, the testimony was valid, where having detected only H antigens, the victim could be eliminated but Dominguez could not. See Part II.A.1 for a description of the problem of masking and non-quantification and discussion of similar cases.
