At the 1982 trial, the case of the prosecution rested heavily on the testimony of Harold Davis, who claimed that he had been just 10 feet away from the crime scene and saw Philip Workman shoot Lt. Oliver. In November 1999, Harold Davis retracted his testimony, claiming that he called in the false lead to collect money to support his drug habit. Davis claims that he was threatened that harm would come to his family members should he change his testimony. Several other eyewitnesses have testified that they did not see Davis at the scene and the police report on the crime scene never noted Davis's presence. Steve Craig, an eyewitness to the shooting who did not testify at the trial due to illness, signed a statement in 1995 that he had a clear view of the parking lot and that he had not seen Davis.
