Item 52 — Bundy Blood Drop Five-Probe RFLP Result
Item 52, a Bundy blood drop discussed as having a Cellmark five-probe RFLP match to Simpson. Witnesses and counsel reported frequencies beginning at 1 in 170 million, with upper figures ranging from 1.2 billion to 2.2 billion. Testimony and argument gave differing DNA-quantity figures, including approximately 200–250 nanograms and approximately 25 nanograms; Dr. Gerdes challenged the result as potentially contaminated based on the latter figure. Counsel cited the result in opening and closing arguments, while objections were sustained to some cross-examination references concerning Cellmark's testing and DNA quantity.
