Media investigations over the years, however, including my own for The Huffington Post and Reason magazine, have revealed that both Hayne and West have contributed critical evidence that led to the convictions of people who were later exonerated, and routinely and flagrantly flouted the ethical and professional standards of their respective fields. West, for example, once claimed he could match the bite marks in a half-eaten bologna sandwich found at a murder scene to the teeth of the prime suspect. In a more recent case, Hayne claimed the bullet wounds in a murder victim showed that two people held the gun when it was fired, not one. In the Mabry case, West used bite-mark analysis to nab an innocent man for Mabry’s murder. That man spent nearly a year in jail. But the Mabry story also shows that the victims in this scandal include not just the wrongly accused, but the families of the victims, the future victims of the actual perpetrators, public officials like Roseman, and even entire towns.

Mississippi officials have thus far resisted calls for a thorough review of Hayne and West’s work. In particular, the Mississippi Supreme Court has shown little concern over the possibility that Hayne and West may have put an untold number of innocents behind the razor wire at Parchman penitentiary. Neither has Attorney General Jim Hood, whose office continues to defend convictions won primarily on the testimony one or both of the men have given on the witness stand. To concede there’s a problem would implicate many state officials who used the two men during tenures as prosecutors. It would also open hundreds, perhaps thousands of cases to review.
