The Devil & Sherlock Holmes: Tales of Murder, Madness & Obsession Page 9
Seeking to bolster their theory of the crime, prosecutors turned to John Lentini, the fire expert, and John DeHaan, another leading investigator and textbook author. Despite some of the weaknesses of the case, Lentini told me that, given the classic burn patterns and puddle configurations in the house, he was sure that Lewis had set the fire: “I was prepared to testify and send this guy to Old Sparky”—the electric chair.
To discover the truth, the investigators, with the backing of the prosecution, decided to conduct an elaborate experiment and re-create the fire scene. Local officials gave the investigators permission to use a condemned house next to Lewis’s home, which was about to be torn down. The two houses were virtually identical, and the investigators refurbished the condemned one with the same kind of carpeting, curtains, and furniture that had been in Lewis’s home. The scientists also wired the building with heat and gas sensors that could withstand fire. The cost of the experiment came to twenty thousand dollars. Without using liquid accelerant, Lentini and DeHaan set the couch in the living room on fire, expecting that the experiment would demonstrate that Lewis’s version of events was implausible.
The investigators watched as the fire quickly consumed the couch, sending upward a plume of smoke that hit the ceiling and spread outward, creating a thick layer of hot gases overhead—an efficient radiator of heat. Within three minutes, this cloud, absorbing more gases from the fire below, was banking down the walls and filling the living room. As the cloud approached the floor, its temperature rose, in some areas, to more than eleven hundred degrees Fahrenheit. Suddenly, the entire room exploded in flames, as the radiant heat ignited every piece of furniture, every curtain, every possible fuel source, even the carpeting. The windows shattered.
The fire had reached what is called “flashover”—the point at which radiant heat causes a fire in a room to become a room on fire. Arson investigators knew about the concept of flashover, but it was widely believed to take much longer to occur, especially without a liquid accelerant. From a single fuel source—a couch—the room had reached flashover in four and a half minutes.
Because all the furniture in the living room had ignited, the blaze went from a fuel-controlled fire to a ventilation-controlled fire—or what scientists call “post-flashover.” During post-flashover, the path of the fire depends on new sources of oxygen, from an open door or window. One of the fire investigators, who had been standing by an open door in the living room, escaped moments before the oxygen-starved fire roared out of the room into the hallway—a fireball that caused the corridor to go quickly into flashover as well, propelling the fire out the front door and onto the porch.
After the fire was extinguished, the investigators inspected the hallway and living room. On the floor were irregularly shaped burn patterns that perfectly resembled pour patterns and puddle configurations. It turned out that these classic signs of arson can also appear on their own, after flashover. With the naked eye, it is impossible to distinguish between the pour patterns and puddle configurations caused by an accelerant and those caused naturally by post-flashover. The only reliable way to tell the difference is to take samples from the burn patterns and test them in a laboratory for the presence of flammable or combustible liquids.
During the Lime Street experiment, other things happened that were supposed to occur only in a fire fuelled by liquid accelerant: charring along the base of the walls and doorways, and burning under furniture. There was also a V-shaped pattern by the living-room doorway, far from where the fire had started on the couch. In a small fire, a V-shaped burn mark may pinpoint where a fire began, but during post-flashover these patterns can occur repeatedly, when various objects ignite.
One of the investigators muttered that they had just helped prove the defense’s case. Given the reasonable doubt raised by the experiment, the charges against Lewis were soon dropped. The Lime Street experiment had demolished prevailing notions about fire behavior. Subsequent tests by scientists showed that, during post-flashover, burning under beds and furniture was common, entire doors were consumed, and aluminum thresholds melted.
John Lentini says of the Lime Street Fire, “This was my epiphany. I almost sent a man to die based on theories that were a load of crap.”
Hurst next examined a floor plan of Willingham’s house that Vasquez had drawn, which delineated all the purported pour patterns and puddle configurations. Because the windows had blown out of the children’s room, Hurst knew that the fire had reached flashover. With his finger, Hurst traced along Vasquez’s diagram the burn trailer that had gone from the children’s room, turned right in the hallway, and headed out the front door. John Jackson, the prosecutor, had told me that the path was so “bizarre” that it had to have been caused by a liquid accelerant. But Hurst concluded that it was a natural product of the dynamics of fire during post-flashover. Willingham had fled out the front door, and the fire simply followed the ventilation path, toward the opening. Similarly, when Willingham had broken the windows in the children’s room, flames had shot outward.
Hurst recalled that Vasquez and Fogg had considered it impossible for Willingham to have run down the burning hallway without scorching his bare feet. But if the pour patterns and puddle configurations were a result of a flashover, Hurst reasoned, then they were consonant with Willingham’s explanation of events. When Willingham exited his bedroom, the hallway was not yet on fire; the flames were contained within the children’s bedroom, where, along the ceiling, he saw the “bright lights.” Just as the investigator safely stood by the door in the Lime Street experiment seconds before flashover, Willingham could have stood close to the children’s room without being harmed. (Prior to the Lime Street case, fire investigators had generally assumed that carbon monoxide diffuses quickly through a house during a fire. In fact, up until flashover, levels of carbon monoxide can be remarkably low beneath and outside the thermal cloud.) By the time the Corsicana fire achieved flashover, Willingham had already fled outside and was in the front yard.
Vasquez had made a videotape of the fire scene, and Hurst looked at the footage of the burn trailer. Even after repeated viewings, he could not detect three points of origin, as Vasquez had. (Fogg recently told me that he also saw a continuous trailer and disagreed with Vasquez, but added that nobody from the prosecution or the defense ever asked him on the stand about his opinion on the subject.)
After Hurst had reviewed Fogg and Vasquez’s list of more than twenty arson indicators, he believed that only one had any potential validity: the positive test for mineral spirits by the threshold of the front door. But why had the fire investigators obtained a positive reading only in that location? According to Fogg and Vasquez’s theory of the crime, Willingham had poured accelerant throughout the children’s bedroom and down the hallway. Officials had tested extensively in these areas—including where all the pour patterns and puddle configurations were—and turned up nothing. Jackson told me that he “never did understand why they weren’t able to recover” positive tests in these parts.
Hurst found it hard to imagine Willingham pouring accelerant on the front porch, where neighbors could have seen him. Scanning the files for clues, Hurst noticed a photograph of the porch taken before the fire, which had been entered into evidence. Sitting on the tiny porch was a charcoal grill. The porch was where the family barbecued. Court testimony from witnesses confirmed that there had been a grill, along with a container of lighter fluid, and that both had burned when the fire roared onto the porch during post-flashover. By the time Vasquez inspected the house, the grill had been removed from the porch, during cleanup. Though he cited the container of lighter fluid in his report, he made no mention of the grill. At the trial, he insisted that he had never been told of the grill’s earlier placement. Other authorities were aware of the grill but did not see its relevance. Hurst, however, was convinced that he had solved the mystery: when firefighters had blasted the porch with water, they had likely spread charcoal-lighter fluid from the melted container.
Without having visited the fire scene, Hurst says, it was impossible to pinpoint the cause of the blaze. But, based on the evidence, he had little doubt that it was an accidental fire—one caused most likely by the space heater or faulty electrical wiring. It explained why there had never been a motive for the crime. Hurst concluded that there was no evidence of arson, and that a man who had already lost his three children and spent twelve years in jail was about to be executed based on “junk science.” Hurst wrote his report in such a rush that he didn’t pause to fix the typos.
“I am a realist and I will not live a fantasy,” Willingham once told Gilbert about the prospect of proving his innocence. But in February, 2004, he began to have hope. Hurst’s findings had helped to exonerate more than ten people. Hurst even reviewed the scientific evidence against Willingham’s friend Ernest Willis, who had been on death row for a strikingly similar arson charge. Hurst says, “It was like I was looking at the same case. Just change the names.” In his report on the Willis case, Hurst concluded that not “a single item of physical evidence . . . supports a finding of arson.” A second fire expert hired by Ori White, the new district attorney in Willis’s district, concurred. After seventeen years on death row, Willis was set free. “I don’t turn killers loose,” White said at the time. “If Willis was guilty, I’d be retrying him right now. And I’d use Hurst as my witness. He’s a brilliant scientist.” White noted how close the system had come to murdering an innocent man. “He did not get executed, and I thank God for that,” he said.
On February 13th, four days before Willingham was scheduled to be executed, he got a call from Reaves, his attorney. Reaves told him that the fifteen members of the Board of Pardons and Paroles, which reviews an application for clemency and had been sent Hurst’s report, had made their decision.
“What is it?” Willingham asked.
“I’m sorry,” Reaves said. “They denied your petition.”
The vote was unanimous. Reaves could not offer an explanation: the board deliberates in secret, and its members are not bound by any specific criteria. The board members did not even have to review Willingham’s materials, and usually don’t debate a case in person; rather, they cast their votes by fax—a process that has become known as “death by fax.” Between 1976 and 2004, when Willingham filed his petition, the State of Texas had approved only one application for clemency from a prisoner on death row. A Texas appellate judge has called the clemency system “a legal fiction.” Reaves said of the board members, “They never asked me to attend a hearing or answer any questions.”
The Innocence Project obtained, through the Freedom of Information Act, all the records from the governor’s office and the board pertaining to Hurst’s report. “The documents show that they received the report, but neither office has any record of anyone acknowledging it, taking note of its significance, responding to it, or calling any attention to it within the government,” Barry Scheck said. “The only reasonable conclusion is that the governor’s office and the Board of Pardons and Paroles ignored scientific evidence.”
LaFayette Collins, who was a member of the board at the time, told me of the process, “You don’t vote guilt or innocence. You don’t retry the trial. You just make sure everything is in order and there are no glaring errors.” He noted that although the rules allowed for a hearing to consider important new evidence, “in my time there had never been one called.” When I asked him why Hurst’s report didn’t constitute evidence of “glaring errors,” he said, “We get all kinds of reports, but we don’t have the mechanisms to vet them.” Alvin Shaw, another board member at the time, said that the case didn’t “ring a bell,” adding, angrily, “Why would I want to talk about it?” Hurst calls the board’s actions “unconscionable.”
Though Reaves told Willingham that there was still a chance that Governor Perry might grant a thirty-day stay, Willingham began to prepare his last will and testament. He had earlier written Stacy a letter apologizing for not being a better husband and thanking her for everything she had given him, especially their three daughters. “I still know Amber’s voice, her smile, her cool Dude saying and how she said: I wanna hold you! Still feel the touch of Karmon and Kameron’s hands on my face.” He said that he hoped that “some day, somehow the truth will be known and my name cleared.”
He asked Stacy if his tombstone could be erected next to their children’s graves. Stacy, who had for so long expressed belief in Willingham’s innocence, had recently taken her first look at the original court records and arson findings. Unaware of Hurst’s report, she had determined that Willingham was guilty. She denied him his wish, later telling a reporter, “He took my kids away from me.”
Gilbert felt as if she had failed Willingham. Even before his pleas for clemency were denied, she told him that all she could give him was her friendship. He told her that it was enough “to be a part of your life in some small way so that in my passing I can know I was at last able to have felt the heart of another who might remember me when I’m gone.” He added, “There is nothing to forgive you for.” He told her that he would need her to be present at his execution, to help him cope with “my fears, thoughts, and feelings.”
On February 17th, the day he was set to die, Willingham’s parents and several relatives gathered in the prison visiting room. Plexiglas still separated Willingham from them. “I wish I could touch and hold both of you,” Willingham had written to them earlier. “I always hugged Mom but I never hugged Pop much.”
As Willingham looked at the group, he kept asking where Gilbert was. Gilbert had recently been driving home from a store when another car ran a red light and smashed into her. Willingham used to tell her to stay in her kitchen for a day, without leaving, to comprehend what it was like to be confined in prison, but she had always found an excuse not to do it. Now she was paralyzed from the neck down.
While she was in an intensive-care unit, she had tried to get a message to Willingham, but apparently failed. Gilbert’s daughter later read her a letter that Willingham had sent her, telling her how much he had grown to love her. He had written a poem: “Do you want to see beauty—like you have never seen? / Then close your eyes, and open your mind, and come along with me.”
Gilbert, who spent years in physical rehabilitation, gradually regaining motion in her arms and upper body, says, “All that time, I thought I was saving Willingham, and I realized then that he was saving me, giving me the strength to get through this. I know I will one day walk again, and I know it is because Willingham showed me the kind of courage it takes to survive.”
Willingham had requested a final meal, and at 4 P.M. on the seventeenth he was served it: three barbecued pork ribs, two orders of onion rings, fried okra, three beef enchiladas with cheese, and two slices of lemon cream pie. He received word that Governor Perry had refused to grant him a stay. (A spokesperson for Perry says, “The Governor made his decision based on the facts of the case.”) Willingham’s mother and father began to cry. “Don’t be sad, Momma,” Willingham said. “In fifty-five minutes, I’m a free man. I’m going home to see my kids.” Earlier, he had confessed to his parents that there was one thing about the day of the fire he had lied about. He said that he had never actually crawled into the children’s room. “I just didn’t want people to think I was a coward,” he said. Hurst told me, “People who have never been in a fire don’t understand why those who survive often can’t rescue the victims. They have no concept of what a fire is like.”
The warden told Willingham that it was time. Willingham, refusing to assist the process, lay down; he was carried into a chamber eight feet wide and ten feet long. The walls were painted green, and in the center of the room, where an electric chair used to be, was a sheeted gurney. Several guards strapped Willingham down with leather belts, snapping buckles across his arms and legs and chest. A medical team then inserted intravenous tubes into his arms. Each official had a separate role in the process, so that no one person felt responsible for taking
a life.
Willingham had asked that his parents and family not be present in the gallery during this process, but as he looked out he could see Stacy watching; whatever calm he had obtained was lost, and with his last breaths he cursed her. The warden pushed a remote control, and sodium thiopental, a barbiturate, was pumped into Willingham’s body. Then came a second drug, pancuronium bromide, which paralyzes the diaphragm, making it impossible to breathe. Finally, a third drug, potassium chloride, filled his veins until his heart stopped, at 6:20 P.M. On his death certificate, the cause was listed as “Homicide.”
After his death, his parents were allowed to touch his face for the first time in more than a decade. Later, at Willingham’s request, they cremated his body and secretly spread some of his ashes over his children’s graves. He had told his parents, “Please don’t ever stop fighting to vindicate me.”
In December, 2004, questions about the scientific evidence in the Willingham case began to surface. Maurice Possley and Steve Mills, of the Chicago Tribune, had published an investigative series on flaws in forensic science; upon learning of Hurst’s report, Possley and Mills asked three fire experts, including John Lentini, to examine the original investigation. The experts concurred with Hurst’s report. Nearly two years later, the Innocence Project commissioned Lentini and three other top fire investigators to conduct an independent review of the arson evidence in the Willingham case. The panel concluded that “each and every one” of the indicators of arson had been “scientifically proven to be invalid.”
In 2005, Texas established a government commission to investigate allegations of error and misconduct by forensic scientists. The first cases that are being reviewed by the commission are those of Willingham and Willis. In August, 2009, the noted fire scientist Craig Beyler, who was hired by the commission, completed his investigation. In a scathing report, he concluded that investigators in the Willingham case had no scientific basis for claiming that the fire was arson, ignored evidence that contradicted their theory, had no comprehension of flashover and fire dynamics, relied on discredited folklore, and failed to eliminate potential accidental or alternative causes of the fire. He said that Vasquez’s approach seemed to deny “rational reasoning” and was more “characteristic of mystics or psychics.” What’s more, Beyler determined that the investigation violated, as he put it to me, “not only the standards of today but even of the time period.” The commission is reviewing his conclusions, and plans to release its own report. The commission will likely narrowly assess the reliability of the scientific evidence. But some legal scholars believe that its findings could eventually lead to Texas becoming the first state to acknowledge that, since the advent of the modern judicial system, it had carried out the “execution of a legally and factually innocent person.”
