This episode covers the defense's presentation of expert testimony from ARCA in the Karen Reed retrial. Dr. Daniel Wolfe demonstrated that a thrown glass could cause the taillight damage and that the alleged impact speed was insufficient to cause O'Keefe’s skull fracture. Prosecutor Hank Brennan’s cross-examination regarding holes in O'Keefe’s sweatshirt sparked a mistrial motion, which was denied. Dr. Andrew Rentschler then provided biomechanical analysis supporting the defense’s alternative theory before the defense rested its case.
