Brief Quote / Description of Testimony

Victim and Brown were both O secretors. Stains also type O. The analyst testified “I detected the presence of ‘H’ antigens [on the victim’s panties] and that indicates Type-O. And this is the only antigen which I detected, which indicates that it came from either a Type-O secretor or a nonsecretor.” The analyst told the jury that 46.5% of the population could have been the donor. Absent quantification, that statistic regarding a subset of the population was irrelevant and misleading. The relevant statistic was that 100 percent of the population could have been the semen donor.

Quotes from prosecution arguments

“And the things that were presented to the police by Mr. Brown were the ways that he made entry into the house, the fact that he grabbed the victim by her left arm, a description of the couch, a description of the house itself, a description of how the victim was dressed that night, things that only someone who was there would have known. Not things that are going to be printed there in the newspaper that he could have read about, but only things that a person who would have been there would have known.”
