Donald Thompson was an LAPD officer who testified as a witness in both the criminal and civil trials. In the criminal trial, he testified that he had visited the Bundy scene and looked around Rockingham, and that he did not believe it was wrong to handcuff the defendant after Detective Vannatter's statement, given what Thompson knew and had seen that day. His testimony also addressed the Bronco at Rockingham and measures used to protect a crime scene, while his civil-trial examination formed part of broader questioning about police procedures and evidence handling at Bundy and Rockingham on June 13, 1994.
