The defense methodically challenged the prosecution's evidence collection procedures through four key witnesses. Willie Ford testified he saw no socks in Simpson's bedroom during his crime scene video walkthrough, while Detective Luper revealed a brown glove was improperly moved before being photographed. Detective Mulldorfer exposed that the Bronco's storage at Viertel's impound lacked required access logs. Housekeeper Josephine Guarin established Simpson's whereabouts and testified he called her from Knott's Berry Farm the night of the murders.
