Day 75 featured extensive direct examination of DOJ DNA analyst Gary Sims, who presented RFLP analysis showing blood on Simpson's socks matched Nicole Brown and blood inside the Rockingham glove matched Ronald Goldman. The day was largely technical and procedural, but punctuated by defense objections over evidence handling practices, the implications of items tested by defense experts, and the prosecution's presentation of DNA matches without accompanying population frequency statistics. Cotton was excused after contentious rulings on her population frequency testimony.
