text: Testimony of Harold Davis 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 Lieutenant 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.
  Subsequent appellate proceedings, however, failed to establish the falsity of Harold Davis's original testimony. According to the Tennessee Court of Criminal Appeals, Davis's testimony at a 2002 hearing can be "best summarized" by the following exchange:
  Prosecutor: You're not saying you lied, right?
  Davis: Right.
  Prosecutor: Ok. In the trial, you're not saying-
  Davis: Right.
  Prosecutor: -You lied about that?
  Davis: Right. I'm not saying that.
  Prosecutor: You just don't know.
  Davis: I just don't remember. I just don't know . . . .I didn't lie
  The U.S. Court of Appeals, reviewing previous appellate decisions to decide a request for a stay of execution on May 4, 2007, found that, "The Tennessee courts . . . concluded that [the evidence] did not show that Davis lied at the trial. The state trial court found that the testimony did not amount to a recantation and did not show that Davis had lied during the trial."
