Shapiro conducted a devastating cross-examination of Detective Vannatter, methodically exposing critical failures in evidence handling, documentation, and the accuracy of his search warrant affidavit. Key problems emerged including the Rockingham glove appearing in no detective's notes, an unrefrigerated blood sample transported on a car seat for two hours, and the defense argument that handwritten notes showed no blood was found on the socks on June 13, with blood detected only during phenol testing weeks later. Darden's redirect attempts could not fully rehabilitate the detective, and the day ended with Kato Kaelin beginning his testimony.
