Walter had suggested they “go up to the room for a cup of coffee, a smoke, and a little chitchat.” As Walter studied Dunn’s gaunt face and hollow eyes in the yellow lamplight, he recalled his misgivings of the night before. A man weakened by grief and self-pity could not bring his son’s murderer to account. Walter smiled to himself as Henry VI came back to him: “Oft have I heard that grief softens the mind, And makes it fearful and degenerate; Think therefore on revenge and cease to weep.”

A man’s grief could not be denied but it must be “set apart. The pain had to come out first.” Walter tented his fingers beneath his gaunt face. As Dunn spoke, Walter’s small blue eyes varied from steely interest to the softness of utmost patience. The angel of vengeance took many forms; in such a conference, it began with Walter as the ferryman poling parents of murdered children through blood tides of woe.

Dunn had been working late on that Sunday evening in his Bucks County, Pennsylvania, home office when the phone rang. He thought, It must be Scott. The Sunday calls from his twenty-four-year-old son, who had moved to Lubbock, Texas, to make a new life for himself, were a father’s joy. Dunn had urged the move; Lubbock was his beloved childhood home, a friendlier, more wholesome place than the East Coast, a place for Scott to start over. Scott had struggled in school in the East. He tried the U.S. Air Force, then tried community college in Texas and dropped out, but after that things started to come together for him. He had a good job, a job he loved and excelled at. Scott had always shown a mechanical gift. Even as a boy he could take apart anything and put it back together. Now in Lubbock, he got a job in an electronics store installing stereos-and became a star at it. He was a West Texas stereo cowboy. The region had rodeo-style competitions in which the “cowboys” vied for prizes, money, and prestige for the fastest installations and highest quality sound. Scott dominated the competitions. He’d found a way to maintain sound quality at unheard-of volumes by stacking ice on the system. His trophies filled the store. An athletic six foot two, 195 pounds with blond good looks, “The Iceman” also starred in the store’s TV commercials. Women came into the shop to meet him. He’d loaded his own car-an ’87 Camaro he called “Yellow Thunder”-with the finest stereo equipment, and took it booming down the prairie highways. He’d recently told his father he was bringing home for Thanksgiving a young woman named Jessica, a bright, lovely Mississippi State University student-his soon-to-be fiancée.

But the flat, cold voice on the line was someone he’d never heard of.

Her name was Leisha Hamilton.

“Are you Scott Dunn’s father?” she asked.

She was Scott’s live-in girlfriend, she said. She’d found Dunn’s name on a telephone bill. Scott had been missing for four days and she was concerned.

Dunn was confused. “The only girl Scott ever told me about was Jessica.”

Scott had moved out completely, Hamilton said. He’d taken all his clothes and just left. Even the bed they shared was gone. The only thing he’d left behind was his car, still parked at the office. When Dunn heard that he felt a chill. “I knew then something was really wrong,” Dunn said. “Scott would never go anywhere without his car. It was his baby.”

Hamilton called again, and Dunn recorded her call. Now Walter asked to hear the tape. “She sounds so cold,” Dunn said, as the atonal voice filled the room. “I’ve never heard anything like it.” Walter raised an eyebrow, but said nothing.

The police regarded Scott’s disappearance as a missing person case, but when his son hadn’t returned two weeks later, Dunn flew to Lubbock to push the investigation. Walter listened to Dunn describe his torment when he realized his son had been murdered.

Police ran a luminol test in Scott and Leisha’s emptied bedroom to detect any blood that might have been cleaned off the whitewashed walls. Luminol detects traces of blood as diluted as one part per million. When sprayed on the walls in darkness, even blood that had been cleaned up would interact with the chemical and glow with a blue luminescence for thirty seconds.

The walls glowed as if they had been painted blue. Huge waves and spikes of blood splashed halfway up the wall. There were blood splatters on the door, blood splatters almost to the ceiling. The room was a chamber of horrors. A blood bath had occurred there. DNA tests showed it was Scott’s blood.

Jim’s voice broke as he showed Walter the luminol test photos. Scott had died in that room, Jim was now convinced.

Police, too, were convinced they had a murder on their hands. But if Scott had been killed, they couldn’t find his body.

They’d combed the prairie with cadaver dogs and helicopters, turned over half the city dump, even brought in psychics, to no avail. “In Texas, the state can’t bring murder charges without a weapon, body, or body part,” the DA told Dunn. “You don’t have a case.”

With no body, police flailed trying to find suspects. They’d interviewed everyone Scott knew, including his colleagues at the car-stereo installation shop, but nobody stood out. Leisha was being very cooperative with the police. She didn’t know why Scott had up and gone, although she speculated that he may have run off with another woman-women adored Scott. She had no idea how her bedroom had become soaked with Scott’s blood.

The police thought she wasn’t being completely forthcoming, but they figured she was scared and they hoped to coax her into greater trust. They didn’t want to frighten her into not cooperating. There was no way the helpful, petite, twenty-eight-year-old woman committed murder.

Dizzy with grief, Dunn had pressed every power from the FBI in Washington to the governor of Texas, George Bush, to take an interest in the case, to no avail. He stalked the West Texas prairie looking for the body himself, and spent hours talking to psychics in Baltimore and Philadelphia.

Dunn went to Texas and took Hamilton out to dinner to form an alliance with her in his cause. After that, Leisha kept calling, but her phone calls grew darker. One day she’d say she loved Scott and was doing all she could to find him; in warm tones, she expressed deep sympathy for Jim. The next day, she’d sound vague and distant, hinting that she might know where Scott’s body was, but Jim would never find him. Growing suspicious of Hamilton and frustrated by the police, Dunn did his own sleuthing. He traveled to New Mexico to investigate reports that Leisha had once been jailed for passing bad checks. But he was always eager to hear from her. Of everyone in the West Texas world where Dunn had sent his son, she seemed to know Scott best. Since she was the closest to Scott, Hamilton said, she thought it was only fair that she get his car. She kept pressing Dunn to give her the keys.

The thin man sitting in the Queen Anne chair had said nothing for almost three hours.

Dunn’s voice cracked. “Well, Mr. Walter, what do you think I should do? Is there a case here?”

Walter stubbed out his cigarette and stared hard at Dunn.

“Jim, aren’t you tired of being the grieving father?”

Dunn’s mouth fell open. “I… I thought that was what I was supposed to be.”

Walter shook his head. His jaw was clenched.

“No! You’re supposed to be goddamn mad! That bitch murdered your son! Let’s go get her!”

Dunn sat stunned as the profiler stared at him, awaiting a response.

Slowly, Dunn’s gaunt face creased in a big, toothy smile.

“I’m in,” he said.

But Walter still had concerns about Dunn’s emotional frailty, and he addressed them immediately.

“First we must encapsulate the difference between your emotional issues and the things we need to do with solving the case,” he said. “As for your love or anger or hatred or whatever else, you must express these things in terms of your son, but not let it bleed over into the case because it dilutes it and you start to misplace emotion into the structural issues and you don’t know where you’re at. I certainly don’t have a problem chatting with you about internal things, things that are important, but we need to do business on a different plane. We need a cold, businesslike approach.”
