Recent Cases of Possible Mistaken Executions
Since the death penalty was reinstated in 1976, there have been inmates with reasonably credible claims of innocence who were nevertheless executed, some without a full review of those claims. In 1992, for example, Roger Keith Coleman made headlines with his dual plea that he was innocent and that no court would review his evidence.40
Coleman's representation at trial was shoddy. On appeal, his new attorneys misread the state statute governing the time for submitting an appeal and filed their brief a day too late. The Virginia state courts held that this late filing was the same as no filing and refused to review his issues. The federal courts then said that he could not raise a federal claim because he had waived his state review. Finally, the Supreme Court said that he could not complain that it was his attorney who erred, since he was not entitled to an attorney in the first place.41 Coleman was executed without a full review of his innocence claims.
Leonel Herrera may have been innocent, but he was not innocent enough to satisfy the Supreme Court.42 A former Texas judge submitted an affidavit stating that another man had confessed to the crime for which Herrera was facing execution. Numerous other pieces of new evidence also threw doubt on his conviction. Still, the Court said that at this late stage of his appeal, he needed an extraordinary amount of proof to stop his execution. He was executed in Texas in 1993.
Another kind of innocence was illustrated in the case of Jesse Jacobs, who was executed in Texas on January 4, 1995.43 Jacobs had been convicted and sentenced to death after the state had put on evidence to show that he was the actual killer in an abduction ending in murder which also involved a co-defendant. At the later trial of the co-defendant, the state reversed its story and said it was the co-defendant, not Jacobs, who pulled the trigger. In fact, the prosecution used (and thus vouched for) Jacobs's own testimony that he did not do the shooting and did not even know that his co-defendant had a gun. The co-defendant was also convicted, though not sentenced to death. Despite the admission by the prosecution that the arguments they made at Jacobs's trial were false, Jacobs was executed.
Jacobs was not innocent in the full sense of the word. He had admittedly participated in the underlying crime, but it is doubtful that the jury would have sentenced him to death if the prosecutors had acknowledged that he was not directly involved in the actual murder. Three Supreme Court Justices were highly critical of this deception on the prosecution's part. Justice Stevens wrote: "It would be fundamentally unfair to execute a person on the basis of a factual determination that the state has formally disavowed. I find this course of events deeply troubling."44
Senator Arlen Specter, an ardent death penalty supporter and former district attorney, was also distressed at this development, and in addressing the Senate he warned against such impositions of the death penalty in "a callous or unreasonable fashion."45 The European Parliament likewise passed a resolution expressing "shock" at this execution; there were no votes opposing the resolution.46
The recent execution of Coleman Wayne Gray in Virginia is another example of improper state tactics used to tip the balance toward a death sentence. At the time of Gray's sentencing hearing, the state circumvented the rules of disclosure and at the last minute raised the prospect of other notorious offenses by Gray (even though he had not been charged in these alleged offenses). With no chance to adequately refute these allegations, Gray was sentenced to death. Federal District Court Judge James Spencer found the state's action unfair, but found himself constrained by the new Anti-Terrorism and Effective Death Penalty Act of 1996 from granting Gray any relief. He wrote: "One cannot morally support the death penalty without some assurance, by evidence or faith, that the ultimate penalty is imposed fairly." Gray was executed on February 26, 1997.47
