The Devil & Sherlock Holmes: Tales of Murder, Madness & Obsession Page 8

  Another inmate, Ernest Ray Willis, had a case that was freakishly similar to Willingham’s. In 1987, Willis had been convicted of setting a fire, in West Texas, that killed two women. Willis told investigators that he had been sleeping on a friend’s living-room couch and woke up to a house full of smoke. He said that he tried to rouse one of the women, who was sleeping in another room, but the flames and smoke drove him back, and he ran out the front door before the house exploded with flames. Witnesses maintained that Willis had acted suspiciously; he moved his car out of the yard, and didn’t show “any emotion,” as one volunteer firefighter put it. Authorities also wondered how Willis could have escaped the house without burning his bare feet. Fire investigators found pour patterns, puddle configurations, and other signs of arson. The authorities could discern no motive for the crime, but concluded that Willis, who had no previous record of violence, was a sociopath—a “demon,” as the prosecutor put it. Willis was charged with capital murder and sentenced to death.

  Willis had eventually obtained what Willingham called, enviously, a “bad-ass lawyer.” James Blank, a noted patent attorney in New York, was assigned Willis’s case as part of his firm’s pro-bono work. Convinced that Willis was innocent, Blank devoted more than a dozen years to the case, and his firm spent millions, on fire consultants, private investigators, forensic experts, and the like. Willingham, meanwhile, relied on David Martin, his court-appointed lawyer, and one of Martin’s colleagues to handle his appeals. Willingham often told his parents, “You don’t know what it’s like to have lawyers who won’t even believe you’re innocent.” Like many inmates on death row, Willingham eventually filed a claim of inadequate legal representation. (When I recently asked Martin about his representation of Willingham, he said, “There were no grounds for reversal, and the verdict was absolutely the right one.” He said of the case, “Shit, it’s incredible that anyone’s even thinking about it.”)

  Willingham tried to study the law himself, reading books such as “Tact in Court, or How Lawyers Win: Containing Sketches of Cases Won by Skill, Wit, Art, Tact, Courage and Eloquence.” Still, he confessed to a friend, “The law is so complicated it is hard for me to understand.” In 1996, he obtained a new court-appointed lawyer, Walter Reaves, who told me that he was appalled by the quality of Willingham’s defense at trial and on appeal. Reaves prepared for him a state writ of habeas corpus, known as a Great Writ. In the byzantine appeals process of death-penalty cases, which frequently takes more than ten years, the writ is the most critical stage: a prisoner can introduce new evidence detailing such things as perjured testimony, unreliable medical experts, and bogus scientific findings. Yet most indigent inmates, like Willingham, who constitute the bulk of those on death row, lack the resources to track down new witnesses or dig up fresh evidence. They must depend on court-appointed lawyers, many of whom are “unqualified, irresponsible, or overburdened,” as a study by the Texas Defender Service, a nonprofit organization, put it. In 2000, a Dallas Morning News investigation revealed that roughly a quarter of the inmates condemned to death in Texas were represented by court-appointed attorneys who had, at some point in their careers, been “reprimanded, placed on probation, suspended or banned from practicing law by the State Bar.” Although Reaves was more competent, he had few resources to reinvestigate the case, and his writ introduced no new exculpatory evidence: nothing further about Webb, or the reliability of the eyewitness testimony, or the credibility of the medical experts. It focussed primarily on procedural questions, such as whether the trial court erred in its instructions to the jury.

  The Texas Court of Criminal Appeals was known for upholding convictions even when overwhelming exculpatory evidence came to light. In 1997, DNA testing proved that sperm collected from a rape victim did not match Roy Criner, who had been sentenced to ninety-nine years for the crime. Two lower courts recommended that the verdict be overturned, but the Court of Criminal Appeals upheld it, arguing that Criner might have worn a condom or might not have ejaculated. Sharon Keller, who is now the presiding judge on the court, stated in a majority opinion, “The new evidence does not establish innocence.” In 2000, George W. Bush pardoned Criner. (Keller was recently charged with judicial misconduct, for refusing to keep open past five o’clock a clerk’s office in order to allow a last-minute petition from a man who was executed later that night.)

  On October 31, 1997, the Court of Criminal Appeals denied Willingham’s writ. After Willingham filed another writ of habeas corpus, this time in federal court, he was granted a temporary stay. In a poem, Willingham wrote, “One more chance, one more strike / Another bullet dodged, another date escaped.”

  Willingham was entering his final stage of appeals. As his anxieties mounted, he increasingly relied upon Gilbert to investigate his case and for emotional support. “She may never know what a change she brought into my life,” he wrote in his diary. “For the first time in many years she gave me a purpose, something to look forward to.”

  As their friendship deepened, he asked her to promise him that she would never disappear without explanation. “I already have that in my life,” he told her.

  Together, they pored over clues and testimony. Gilbert says that she would send Reaves leads to follow up, but although he was sympathetic, nothing seemed to come of them. In 2002, a federal court of appeals denied Willingham’s writ without even a hearing. “Now I start the last leg of my journey,” Willingham wrote to Gilbert. “Got to get things in order.”

  He appealed to the U.S. Supreme Court, but in December, 2003, he was notified that it had declined to hear his case. He soon received a court order announcing that “the Director of the Department of Criminal Justice at Huntsville, Texas, acting by and through the executioner designated by said Director . . . is hereby DIRECTED and COMMANDED, at some hour after 6:00 p.m. on the 17th day of February, 2004, at the Department of Criminal Justice in Huntsville, Texas, to carry out this sentence of death by intravenous injection of a substance or substances in a lethal quantity sufficient to cause the death of said Cameron Todd Willingham.”

  Willingham wrote a letter to his parents. “Are you sitting down?” he asked, before breaking the news. “I love you both so much,” he said.

  His only remaining recourse was to appeal to the governor of Texas, Rick Perry, a Republican, for clemency. The process, considered the last gatekeeper to the executioner, has been called by the U.S. Supreme Court “the ‘fail safe’ in our criminal justice system.”

  One day in January, 2004, Dr. Gerald Hurst, an acclaimed scientist and fire investigator, received a file describing all the evidence of arson gathered in Willingham’s case. Gilbert had come across Hurst’s name and, along with one of Willingham’s relatives, had contacted him, seeking his help. After their pleas, Hurst had agreed to look at the case pro bono, and Reaves, Willingham’s lawyer, had sent him the relevant documents, in the hope that there were grounds for clemency.

  Hurst opened the file in the basement of his house in Austin, which served as a laboratory and an office, and was cluttered with microscopes and diagrams of half-finished experiments. Hurst was nearly six and a half feet tall, though his stooped shoulders made him seem considerably shorter, and he had a gaunt face that was partly shrouded by long gray hair. He was wearing his customary outfit: black shoes, black socks, a black T-shirt, and loose-fitting black pants supported by black suspenders. In his mouth was a wad of chewing tobacco.

  A child prodigy who was raised by a sharecropper during the Great Depression, Hurst used to prowl junk yards, collecting magnets and copper wires in order to build radios and other contraptions. In the early sixties, he received a Ph.D. in chemistry from Cambridge University, where he started to experiment with fluorine and other explosive chemicals, and once detonated his lab. Later, he worked as the chief scientist on secret weapons programs for several American companies, designing rockets and deadly fire bombs—or what he calls “god-awful things.” He helped patent what has been described, with only slight ex
aggeration, as “the world’s most powerful nonnuclear explosive”: an Astrolite bomb. He experimented with toxins so lethal that a fraction of a drop would rot human flesh, and in his laboratory he often had to wear a pressurized moon suit; despite such precautions, exposure to chemicals likely caused his liver to fail, and in 1994 he required a transplant. Working on what he calls “the dark side of arson,” he retrofitted napalm bombs with Astrolite, and developed ways for covert operatives in Vietnam to create bombs from local materials, such as chicken manure and sugar. He also perfected a method for making an exploding T-shirt by nitrating its fibres.

  His conscience eventually began pricking him. “One day, you wonder, What the hell am I doing?” he recalls. He left the defense industry, and went on to invent the Mylar balloon, an improved version of Liquid Paper, and Kinepak, a kind of explosive that reduces the risk of accidental detonation. Because of his extraordinary knowledge of fire and explosives, companies in civil litigation frequently sought his help in determining the cause of a blaze. By the nineties, Hurst had begun devoting significant time to criminal-arson cases, and, as he was exposed to the methods of local and state fire investigators, he was shocked by what he saw.

  Many arson investigators, it turned out, had only a high-school education. In most states, in order to be certified, investigators had to take a forty-hour course on fire investigation, and pass a written exam. Often, the bulk of an investigator’s training came on the job, learning from “old-timers” in the field, who passed down a body of wisdom about the telltale signs of arson, even though a study in 1977 warned that there was nothing in “the scientific literature to substantiate their validity.”

  In 1992, the National Fire Protection Association, which promotes fire prevention and safety, published its first scientifically based guidelines to arson investigation. Still, many arson investigators believed that what they did was more an art than a science—a blend of experience and intuition. In 1997, the International Association of Arson Investigators filed a legal brief arguing that arson sleuths should not be bound by a 1993 Supreme Court decision requiring experts who testified at trials to adhere to the scientific method. What arson sleuths did, the brief claimed, was “less scientific.” By 2000, after the courts had rejected such claims, arson investigators increasingly recognized the scientific method, but there remained great variance in the field, with many practitioners still relying on the unverified techniques that had been used for generations. “People investigated fire largely with a flat-earth approach,” Hurst told me. “It looks like arson—therefore, it’s arson.” He went on, “My view is you have to have a scientific basis. Otherwise, it’s no different than witch-hunting.”

  In 1998, Hurst investigated the case of a woman from North Carolina named Terri Hinson, who was charged with setting a fire that killed her seventeen-month-old son, and faced the death penalty. Hurst ran a series of experiments re-creating the conditions of the fire, which suggested that it had not been arson, as the investigators had claimed; rather, it had started accidentally, from a faulty electrical wire in the attic. Because of this research, Hinson was freed. John Lentini, a fire expert and the author of a leading scientific textbook on arson, describes Hurst as “brilliant.” A Texas prosecutor once told the Chicago Tribune, of Hurst, “If he says it was an arson fire, then it was. If he says it wasn’t, then it wasn’t.”

  Hurst’s patents yielded considerable royalties, and he could afford to work pro bono on an arson case for months, even years. But he received the files on Willingham’s case only a few weeks before Willingham was scheduled to be executed. As Hurst looked through the case records, a statement by Manuel Vasquez, the state deputy fire marshal, jumped out at him. Vasquez had testified that, of the roughly twelve hundred to fifteen hundred fires he had investigated, “most all of them” were arson. This was an oddly high estimate; the Texas State Fire Marshals Office typically found arson in only fifty per cent of its cases.

  Hurst was also struck by Vasquez’s claim that the Willingham blaze had “burned fast and hot” because of a liquid accelerant. The notion that a flammable or combustible liquid caused flames to reach higher temperatures had been repeated in court by arson sleuths for decades. Yet the theory was nonsense: experiments have proved that wood and gasoline-fuelled fires burn at essentially the same temperature.

  Vasquez and Fogg had cited as proof of arson the fact that the front door’s aluminum threshold had melted. “The only thing that can cause that to react is an accelerant,” Vasquez said. Hurst was incredulous. A natural-wood fire can reach temperatures as high as two thousand degrees Fahrenheit—far hotter than the melting point for aluminum alloys, which ranges from a thousand to twelve hundred degrees. And, like many other investigators, Vasquez and Fogg mistakenly assumed that wood charring beneath the aluminum threshold was evidence that, as Vasquez put it, “a liquid accelerant flowed underneath and burned.” Hurst had conducted myriad experiments showing that such charring was caused simply by the aluminum conducting so much heat. In fact, when liquid accelerant is poured under a threshold a fire will extinguish, because of a lack of oxygen. (Other scientists had reached the same conclusion.) “Liquid accelerants can no more burn under an aluminum threshold than can grease burn in a skillet even with a loose-fitting lid,” Hurst declared in his report on the Willingham case.

  Hurst then examined Fogg and Vasquez’s claim that the “brown stains” on Willingham’s front porch were evidence of “liquid accelerant,” which had not had time to soak into the concrete. Hurst had previously performed a test in his garage, in which he poured charcoal-lighter fluid on the concrete floor, and lit it. When the fire went out, there were no brown stains, only smudges of soot. Hurst had run the same experiment many times, with different kinds of liquid accelerants, and the result was always the same. Brown stains were common in fires; they were usually composed of rust or gunk from charred debris that had mixed with water from fire hoses.

  Another crucial piece of evidence implicating Willingham was the “crazed glass” that Vasquez had attributed to the rapid heating from a fire fuelled with liquid accelerant. Yet, in November of 1991, a team of fire investigators had inspected fifty houses in the hills of Oakland, California, which had been ravaged by brush fires. In a dozen houses, the investigators discovered crazed glass, even though a liquid accelerant had not been used. Most of these houses were on the outskirts of the blaze, where firefighters had shot streams of water; as the investigators later wrote in a published study, they theorized that the fracturing had been induced by rapid cooling, rather than by sudden heating—thermal shock had caused the glass to contract so quickly that it settled disjointedly. The investigators then tested this hypothesis in a laboratory. When they heated glass, nothing happened. But each time they applied water to the heated glass the intricate patterns appeared. Hurst had seen the same phenomenon when he had blowtorched and cooled glass during his research at Cambridge. In his report, Hurst wrote that Vasquez and Fogg’s notion of crazed glass was no more than an “old wives’ tale.”

  Hurst then confronted some of the most devastating arson evidence against Willingham: the burn trailer, the pour patterns and puddle configurations, the V-shape and other burn marks indicating that the fire had multiple points of origin, the burning underneath the children’s beds. There was also the positive test for mineral spirits by the front door, and Willingham’s seemingly implausible story that he had run out of the house without burning his bare feet.

  As Hurst read through more of the files, he noticed that Willingham and his neighbors had described the windows in the front of the house suddenly exploding and flames roaring forth. It was then that Hurst thought of the legendary Lime Street Fire, one of the most pivotal in the history of arson investigation.

  On the evening of October 15, 1990, a thirty-five-year-old man named Gerald Wayne Lewis was found standing in front of his house on Lime Street in Jacksonville, Florida, holding his three-year-old son. His two-story wood-frame home was engul
fed in flames. By the time the fire had been extinguished, six people were dead, including Lewis’s wife. Lewis said that he had rescued his son but was unable to get to the others, who were upstairs.

  When fire investigators examined the scene, they found the classic signs of arson: low burns along the walls and floors, pour patterns and puddle configurations, and a burn trailer running from the living room into the hallway. Lewis claimed that the fire had started accidentally, on a couch in the living room—his son had been playing with matches. But a V-shaped pattern by one of the doors suggested that the fire had originated elsewhere. Some witnesses told authorities that Lewis seemed too calm during the fire and had never tried to get help. According to the Los Angeles Times, Lewis had previously been arrested for abusing his wife, who had taken out a restraining order against him. After a chemist said that he had detected the presence of gasoline on Lewis’s clothing and shoes, a report by the sheriff’s office concluded, “The fire was started as a result of a petroleum product being poured on the front porch, foyer, living room, stairwell and second floor bedroom.” Lewis was arrested and charged with six counts of murder. He faced the death penalty.

  Subsequent tests, however, revealed that the laboratory identification of gasoline was wrong. Moreover, a local news television camera had captured Lewis in a clearly agitated state at the scene of the fire, and investigators discovered that at one point he had jumped in front of a moving car, asking the driver to call the Fire Department.
