Abstract

Our description of Cellmark Diagnostics' error in the case of People v. John Ivan Kocak (Superior Court of San Diego County, California, No. 110465) was based on a transcript of sworn testimony by a Cellmark Diagnostics witness. During direct and cross examination, this witness testified that Cellmark had found an STR DNA profile consistent with Mr. Kocak's profile in what was purported to be a mixture of semen and blood on a cotton cloth that had been used by a rapist to wipe himself after a sexual assault. The testimony provided powerful support for the prosecution's contention that Mr. Kocak was the source of that stain.
