Did Texas execute an innocent man?

From The New Yorker by David Grann:

The fire moved quickly through the house, a one-story wood-frame structure in a working-class neighborhood of Corsicana, in northeast Texas. Flames spread along the walls, bursting through doorways, blistering paint and tiles and furniture. Smoke pressed against the ceiling, then banked downward, seeping into each room and through crevices in the windows, staining the morning sky.

Buffie Barbee, who was eleven years old and lived two houses down, was playing in her back yard when she smelled the smoke. She ran inside and told her mother, Diane, and they hurried up the street; that’s when they saw the smoldering house and Cameron Todd Willingham standing on the front porch, wearing only a pair of jeans, his chest blackened with soot, his hair and eyelids singed. He was screaming, “My babies are burning up!” His children—Karmon and Kameron, who were one-year-old twin girls, and two-year-old Amber—were trapped inside.

Willingham told the Barbees to call the Fire Department, and while Diane raced down the street to get help he found a stick and broke the children’s bedroom window. Fire lashed through the hole. He broke another window; flames burst through it, too, and he retreated into the yard, kneeling in front of the house. A neighbor later told police that Willingham intermittently cried, “My babies!” then fell silent, as if he had “blocked the fire out of his mind.”

Diane Barbee, returning to the scene, could feel intense heat radiating off the house. Moments later, the five windows of the children’s room exploded and flames “blew out,” as Barbee put it. Within minutes, the first firemen had arrived, and Willingham approached them, shouting that his children were in their bedroom, where the flames were thickest. A fireman sent word over his radio for rescue teams to “step on it.”

...........................

Todd Willingham, looking on, appeared to grow more hysterical, and a police chaplain named George Monaghan led him to the back of a fire truck and tried to calm him down. Willingham explained that his wife, Stacy, had gone out earlier that morning, and that he had been jolted from sleep by Amber screaming, “Daddy! Daddy!”

“My little girl was trying to wake me up and tell me about the fire,” he said, adding, “I couldn’t get my babies out.”

While he was talking, a fireman emerged from the house, cradling Amber. As she was given C.P.R., Willingham, who was twenty-three years old and powerfully built, ran to see her, then suddenly headed toward the babies’ room. Monaghan and another man restrained him. “We had to wrestle with him and then handcuff him, for his and our protection,” Monaghan later told police. “I received a black eye.” One of the first firemen at the scene told investigators that, at an earlier point, he had also held Willingham back. “Based on what I saw on how the fire was burning, it would have been crazy for anyone to try and go into the house,” he said.

.......................................

Fire investigators, meanwhile, tried to determine the cause of the blaze. (Willingham gave authorities permission to search the house: “I know we might not ever know all the answers, but I’d just like to know why my babies were taken from me.”) Douglas Fogg, who was then the assistant fire chief in Corsicana, conducted the initial inspection. He was tall, with a crew cut, and his voice was raspy from years of inhaling smoke from fires and cigarettes. He had grown up in Corsicana and, after graduating from high school, in 1963, he had joined the Navy, serving as a medic in Vietnam, where he was wounded on four occasions. He was awarded a Purple Heart each time. After he returned from Vietnam, he became a firefighter, and by the time of the Willingham blaze he had been battling fire—or what he calls “the beast”—for more than twenty years, and had become a certified arson investigator. “You learn that fire talks to you,” he told me.

He was soon joined on the case by one of the state’s leading arson sleuths, a deputy fire marshal named Manuel Vasquez, who has since died. Short, with a paunch, Vasquez had investigated more than twelve hundred fires. Arson investigators have always been considered a special breed of detective. In the 1991 movie “Backdraft,” a heroic arson investigator says of fire, “It breathes, it eats, and it hates. The only way to beat it is to think like it. To know that this flame will spread this way across the door and up across the ceiling.” Vasquez, who had previously worked in Army intelligence, had several maxims of his own. One was “Fire does not destroy evidence—it creates it.” Another was “The fire tells the story. I am just the interpreter.” He cultivated a Sherlock Holmes-like aura of invincibility. Once, he was asked under oath whether he had ever been mistaken in a case. “If I have, sir, I don’t know,” he responded. “It’s never been pointed out.”

Vasquez and Fogg visited the Willinghams’ house four days after the blaze. Following protocol, they moved from the least burned areas toward the most damaged ones. “It is a systematic method,” Vasquez later testified, adding, “I’m just collecting information. . . . I have not made any determination. I don’t have any preconceived idea.”

The men slowly toured the perimeter of the house, taking notes and photographs, like archeologists mapping out a ruin. Upon opening the back door, Vasquez observed that there was just enough space to squeeze past the refrigerator blocking the exit. The air smelled of burned rubber and melted wires; a damp ash covered the ground, sticking to their boots. In the kitchen, Vasquez and Fogg discerned only smoke and heat damage—a sign that the fire had not originated there—and so they pushed deeper into the nine-hundred-and-seventy-five-square-foot building. A central corridor led past a utility room and the master bedroom, then past a small living room, on the left, and the children’s bedroom, on the right, ending at the front door, which opened onto the porch. Vasquez tried to take in everything, a process that he compared to entering one’s mother-in-law’s house for the first time: “I have the same curiosity.”

In the utility room, he noticed on the wall pictures of skulls and what he later described as an image of “the Grim Reaper.” Then he turned into the master bedroom, where Amber’s body had been found. Most of the damage there was also from smoke and heat, suggesting that the fire had started farther down the hallway, and he headed that way, stepping over debris and ducking under insulation and wiring that hung down from the exposed ceiling.

As he and Fogg removed some of the clutter, they noticed deep charring along the base of the walls. Because gases become buoyant when heated, flames ordinarily burn upward. But Vasquez and Fogg observed that the fire had burned extremely low down, and that there were peculiar char patterns on the floor, shaped like puddles.

Vasquez’s mood darkened. He followed the “burn trailer”—the path etched by the fire—which led from the hallway into the children’s bedroom. Sunlight filtering through the broken windows illuminated more of the irregularly shaped char patterns. A flammable or combustible liquid doused on a floor will cause a fire to concentrate in these kinds of pockets, which is why investigators refer to them as “pour patterns” or “puddle configurations.”

The fire had burned through layers of carpeting and tile and plywood flooring. Moreover, the metal springs under the children’s beds had turned white—a sign that intense heat had radiated beneath them. Seeing that the floor had some of the deepest burns, Vasquez deduced that it had been hotter than the ceiling, which, given that heat rises, was, in his words, “not normal.”

Fogg examined a piece of glass from one of the broken windows. It contained a spiderweb-like pattern—what fire investigators call “crazed glass.” Forensic textbooks had long described the effect as a key indicator that a fire had burned “fast and hot,” meaning that it had been fuelled by a liquid accelerant, causing the glass to fracture.

The men looked again at what appeared to be a distinct burn trailer through the house: it went from the children’s bedroom into the corridor, then turned sharply to the right and proceeded out the front door. To the investigators’ surprise, even the wood under the door’s aluminum threshold was charred. On the concrete floor of the porch, just outside the front door, Vasquez and Fogg noticed another unusual thing: brown stains, which, they reported, were consistent with the presence of an accelerant.

The men scanned the walls for soot marks that resembled a “V.” When an object catches on fire, it creates such a pattern, as heat and smoke radiate outward; the bottom of the “V” can therefore point to where a fire began. In the Willingham house, there was a distinct “V” in the main corridor. Examining it and other burn patterns, Vasquez identified three places where fire had originated: in the hallway, in the children’s bedroom, and at the front door. Vasquez later testified that multiple origins pointed to one conclusion: the fire was “intentionally set by human hands.”

By now, both investigators had a clear vision of what had happened. Someone had poured liquid accelerant throughout the children’s room, even under their beds, then poured some more along the adjoining hallway and out the front door, creating a “fire barrier” that prevented anyone from escaping; similarly, a prosecutor later suggested, the refrigerator in the kitchen had been moved to block the back-door exit. The house, in short, had been deliberately transformed into a death trap.

The investigators collected samples of burned materials from the house and sent them to a laboratory that could detect the presence of a liquid accelerant. The lab’s chemist reported that one of the samples contained evidence of “mineral spirits,” a substance that is often found in charcoal-lighter fluid. The sample had been taken by the threshold of the front door.

The fire was now considered a triple homicide, and Todd Willingham—the only person, besides the victims, known to have been in the house at the time of the blaze—became the prime suspect.

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 mid-August, 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 findings, and plans to release its own report next year. Some legal scholars believe that the commission may narrowly assess the reliability of the scientific evidence. There is a chance, however, that Texas could become the first state to acknowledge officially that, since the advent of the modern judicial system, it had carried out the “execution of a legally and factually innocent person.”

Just before Willingham received the lethal injection, he was asked if he had any last words. He said, “The only statement I want to make is that I am an innocent man convicted of a crime I did not commit. I have been persecuted for twelve years for something I did not do. From God’s dust I came and to dust I will return, so the Earth shall become my throne.”
