Kerry Max Cook: Death Row, DNA Evidence, and 2024 Exoneration

Kerry Max Cook is a Texas man who spent nearly 20 years on death row for the 1977 rape and murder of Linda Jo Edwards in Tyler, a crime he did not commit. After three trials, two reversed convictions, and a 1999 no-contest plea that freed him without clearing his name, the Texas Court of Criminal Appeals formally declared him actually innocent on June 19, 2024, 46 years after his original conviction.¹ He has since filed a federal civil rights lawsuit against the City of Tyler, Smith County, and fifteen current and former officers.

The 1977 Murder and Cook’s Arrest

Linda Jo Edwards was a 21-year-old secretary at Texas Eastern University. She was found raped and murdered in her apartment in the summer of 1977, four days after meeting Cook, then 20 years old. Local outrage was intense, and Tyler police moved fast to make an arrest.²

The evidence tying Cook to the killing was thin: a single fingerprint on a sliding glass door. At trial, Tyler police sergeant Douglas Collard testified that the print had been left within six to twelve hours of Edwards’s death, placing Cook at the scene near the time of the murder. Collard later admitted the testimony was false. Fingerprints cannot be dated that way, and he said the district attorney had pressured him to say otherwise.³

Prosecutors also called a jailhouse informant, Edward “Shyster” Jackson, who testified that Cook had confessed to him in a shared cell. Jackson’s account was fabricated. Prosecutors showed him crime scene photos so his story would include accurate details, gave him Valium to help him pass a polygraph after he initially failed, and quietly reduced his own first-degree murder charge to involuntary manslaughter in exchange for his cooperation. He served two years.⁴

The victim’s roommate, Paula Rudolph, had initially told police she saw a slender, tanned man with silver, medium-length hair in Edwards’s room the night of the murder. She assumed the man was Edwards’s boyfriend, a married professor named James Mayfield. Cook had brown, shoulder-length hair. By the 1978 trial, Rudolph identified Cook from the witness stand.⁵

Death Row and Two Decades of Reversals

Cook was convicted and sentenced to death in 1978. Smith County District Attorney A.D. Clark III called Cook a “little pervert” at trial and told jurors he “wouldn’t be surprised if he didn’t eat [the victim’s] body parts.”⁶

The case then cycled through the appellate courts for almost two decades. The conviction was affirmed in 1987, but the U.S. Supreme Court vacated that opinion in 1988, and in 1991 the Texas Court of Criminal Appeals reversed the conviction due to an improper psychiatric evaluation regarding future dangerousness.⁷ A 1992 retrial ended in mistrial after jurors, during deliberations, found a stocking inside the leg of the victim’s jeans. Prosecutors had argued Cook stole it as a “souvenir.” The theory collapsed.⁴

A third trial in 1994, prosecuted by Clark’s successor Jack Skeen, produced another conviction and death sentence.⁸ In 1996, the Texas Court of Criminal Appeals reversed it, finding that “prosecutorial and police misconduct has tainted this entire matter from the outset.”⁶

The time in between was brutal. The Texas Court of Criminal Appeals later described Cook’s years on death row as “nothing short of torturous.”⁴ He was sexually assaulted, forcibly branded with tattoos by other inmates, and attempted suicide in 1990, leaving a note that read, “I really was an innocent man.”⁹

The 1999 No-Contest Plea and the DNA Result

Facing a possible fourth trial in 1999, Cook took a no-contest plea to a reduced murder charge. The deal was unusual. It required no admission of guilt and let him maintain his factual innocence.¹⁰ He accepted it to avoid another death sentence after more than 20 years behind bars, and he did not know that DNA results were about to undercut the state’s entire case.⁶

Two months after his release, DNA analysis of semen on the victim’s underwear excluded Cook. It matched James Mayfield, Edwards’s married ex-lover and former supervisor. The plea freed Cook but left him a convicted murderer in the eyes of the law. “I don’t have any rights left,” he said of living under that status.⁹

What the Evidence Showed About James Mayfield

Mayfield was a 44-year-old married professor whose seventeen-month affair with Edwards had cost him his job at Texas Eastern University and strained his marriage. Edwards had surprised him at his home the night she was killed.⁵

Rudolph had told investigators from the start that she thought the man in the apartment was Mayfield. Witnesses confirmed he often wore white tennis shorts matching what she described. DNA later established that his semen was on Edwards’s underwear.⁷

Investigators also learned Mayfield owned a copy of The Sexual Criminal by J. Paul de River, a law enforcement text with graphic illustrations of sexual mutilation murders that mirrored Edwards’s wounds. He had failed multiple polygraphs. His alibi rested only on his wife and daughter, the latter described by police as a “pathological liar” who had allegedly threatened to kill Edwards days before the murder.⁷

In April 2016, under a grant of complete immunity, Mayfield gave a sworn deposition admitting he had perjured himself across multiple trials and hearings. He acknowledged that he had lied for decades about when he last had sex with Edwards, conceding it had happened the day before her death rather than weeks earlier.¹¹ He was never charged with the murder.

The 2024 Exoneration Ruling

On June 19, 2024, the Texas Court of Criminal Appeals issued Ex Parte Cook, WR-84,565-01, setting aside Cook’s conviction and declaring him actually innocent.¹

Judge Bert Richardson, writing for the majority, described a case “riddled with allegations of State misconduct” and “marked by bookends of deception,” pointing to “uncontroverted Brady violations, proof of false testimony, admissions of perjury, and new scientific evidence.” Richardson wrote that several of the state’s actions went “beyond gross negligence and reach into the realm of intentional deception against the tribunal.” The court concluded: “After being incarcerated on death row for almost twenty torturous years, we hold that Cook has met the burden required for actual innocence and relief is hereby granted.”³

The 2015 filing that led to the ruling had come from the Innocence Project and the Innocence Project of Texas, with attorneys Nina Morrison, Barry Scheck, Gary Udashen, and Bruce Anton representing Cook. It cited six rounds of DNA testing excluding him, the evidence pointing to Mayfield, and allegations that Smith County officials had withheld favorable evidence and ordered the destruction of a highly probative piece of evidence shortly after Texas passed a law that would have let Cook request DNA testing.¹⁰

The Federal Civil Rights Lawsuit

On November 14, 2024, Cook filed a federal civil rights suit in the U.S. District Court for the Eastern District of Texas against the City of Tyler, Smith County, and fifteen current or former law enforcement officers. The case (No. 6:17-cv-00333-JDK) alleges due process violations, malicious prosecution, destruction of evidence, and conspiracy under 42 U.S.C. § 1983.¹²

The amended complaint accuses officers of fabricating a psychological profile, falsifying fingerprint analysis, coercing false statements from jailhouse informants, destroying biological evidence, and systematically suppressing evidence pointing to Mayfield. Cook is seeking compensatory and punitive damages and has requested a jury trial. His attorneys are Anand Swaminathan, Jon Loevy, and Alison Leff of Loevy + Loevy.¹³ In a statement with the filing, Cook said his pursuit of justice was not only for himself but “for the many others who have suffered injustice at the hands of Smith County’s dark history.”¹²
