In 1978 Kerry Max Cook was sentenced to death for the murder of Linda Jo Edwards in Tyler, Texas. In 1999, Cook - whose conviction had been reversed for egregious misconduct - agreed to plead no contest to second degree murder and be released. Soon after, DNA tests determined that semen from the victim's clothing came from her married lover, James Mayfield. This April, Mayfield admitted that he committed perjury at Cook's trial. On June 7, the charges were dismissed. Under Texas procedure, Cook will be officially exonerated after the Texas Court of Criminal Appeals formally grants his petition for a writ of habeas corpus.
