David Grann’s New Yorker story about Cameron Todd Willmingham asked whether Texas executed an innocent man in 2004. Willmingham may not have been the first: Claude Jones was executed in Texas 10 years ago for a liquor-store murder, based on a single hair that was found at the scene of the crime. But a recent DNA analysis has shown that the hair did not belong to Jones and it may have belonged, in fact, to the murder victim. Jones was a career criminal who never admitted to the crime. As his execution neared, he pushed then Governor George W. Bush for a DNA test on the hair, but Bush’s office never brought Jones’ request to the governor’s attention. During Jones’ trial, a forensic expert looked at the hair under a microscope and said it could have been Jones’, but not the victim’s; a DNA test was never performed before Jones’ execution.
