The mansion on Hillside Avenue had been dark for weeks. Throughout December 1971, neighbors in the affluent town of Westfield, New Jersey, watched as lights burned continuously in the windows of the grand Victorian estate known as Breeze Knoll. Classical music drifted from within. But no one ever seemed to be home.
When police finally entered the 19-room mansion on December 7, nearly a month after the List family had last been seen, they found a scene that would haunt investigators for almost two decades. Lying in neat rows on sleeping bags in the ballroom—beneath an ornate Tiffany skylight—were five bodies: Helen List, 46; her children Patricia, 16, John Jr., 15, and Frederick, 13; and the family matriarch, 85-year-old Alma List.
The killer had left behind a five-page confession letter explaining his methodology and motives. But John Emil List, the 46-year-old patriarch who had carefully murdered each member of his family with methodical precision, had disappeared without a trace.
The Perfect Family, Crumbling
To the outside world, the Lists embodied post-war American prosperity. John List, a bespectacled accountant and Army veteran, taught Sunday school at the local Lutheran church. His family attended services faithfully. The mansion, with its marble fireplaces and ballroom, seemed to announce their success to the world.
But beneath the veneer, the foundation was collapsing. List had lost his job at a bank earlier that year. Unable to face the humiliation of unemployment—or worse, welfare—he had spent months pretending to go to work, sitting at the train station reading newspapers while secretly draining his elderly mother’s bank accounts to keep up with the mortgage.
The deception couldn’t last forever. As bills mounted and his family remained oblivious, List arrived at a solution that he would later claim was an act of mercy: he would kill them all.
A Day of Systematic Slaughter
The morning of November 9, 1971, began like any other. List saw his three children off to school. Then he walked into the kitchen where his wife Helen was drinking her morning coffee and shot her in the back of the head. He climbed the stairs to the third floor and killed his mother as she lay in bed.
When Patricia and Frederick returned from school that afternoon, he shot them as they entered the house. But List wasn’t finished. He made himself a sandwich, closed out his remaining bank accounts, and drove to his son John Jr.’s soccer game. He cheered from the sidelines, gave the boy a ride home, and then shot him in the chest.
In the letter he left for his pastor, List explained his twisted logic: the world was full of evil and poverty, and his family might turn away from God if they faced hardship. By killing them, he believed he was ensuring their place in heaven. But List showed no willingness to face earthly consequences for his actions.
He spent the night in the mansion surrounded by the bodies of his family. The next morning, he systematically cleaned the crime scene, canceled deliveries, notified the children’s schools they would be on an extended vacation, and used scissors to cut his face out of every family photograph in the house. Then he turned on the radio to a religious station, left the lights burning, and walked out the door.
The Vanishing Act
For eighteen years, John List simply ceased to exist. His car was found at JFK International Airport, but there was no record of him boarding any flight. With every photograph of him destroyed, investigators had nothing to show potential witnesses. The trail went cold almost immediately.
List had reinvented himself as Robert Peter Clark. He moved to Denver, where he worked as an accountant and attended church regularly—the same habits that had defined his previous life. In 1977, he met a woman at a church social. They married in 1985. His new wife knew nothing of his past.
Meanwhile, the case haunted Westfield. Breeze Knoll mysteriously burned to the ground nine months after the murders, though investigators never determined the cause. Even decades later, local children reportedly refused to walk past the property where the mansion once stood.
An Artist’s Intuition
In 1989, desperate prosecutors made contact with the television show “America’s Most Wanted.” But there was a problem: how do you hunt for a man when you don’t know what he looks like after nearly two decades?
Producer Michael Linder turned to Frank Bender, a Philadelphia forensic sculptor with an uncanny ability to visualize how people aged. Working from old photographs and psychological profiles, Bender created a clay bust showing how List might appear in middle age. He gave him a hawk-like nose, bushy eyebrows, and thick horn-rimmed glasses—theorizing that List would cling to the same style of spectacles from his younger years as a reminder of better times.
When “America’s Most Wanted” aired the episode on May 21, 1989, 22 million viewers saw Bender’s sculpture. The response was immediate.
One tip came from a woman in Richmond, Virginia. Her neighbor, an accountant named Robert Clark who attended church faithfully, looked remarkably like the bust. Authorities followed up, and on June 1, 1989—just eleven days after the broadcast—police arrested John List. His eighteen-year disappearing act was over.
“Without Remorse and Without Honor”
At his 1990 trial, defense attorneys argued that List suffered from post-traumatic stress disorder from his military service in World War II and Korea, and that he had been experiencing a midlife crisis. Psychologists testified about his mental state. But the prosecution’s case was overwhelming: five innocent victims, murder weapons, and List’s own written confession.
The jury deliberated and found him guilty on all counts.
At sentencing, the judge’s words were searing. “John Emil List is without remorse and without honor,” he declared. “After 18 years, five months, and 22 days, it is now time for the voices of Helen, Alma, Patricia, Frederick, and John F. List to rise from the grave.”
List received five consecutive life sentences.
A Killer’s Delusion
In a 2002 television interview, List offered a chilling window into his psyche. He explained that he hadn’t killed himself after murdering his family because suicide would have prevented him from reaching heaven. His hope remained that in the afterlife, his family would either forgive him or simply not remember what had happened.
“I feel when we get to heaven we won’t worry about these earthly things,” he said, still clinging to the delusion that had allowed him to murder five people and sleep soundly for eighteen years.

List, who says he remains deeply religious today, acknowledges that his crimes violated one of the Ten Commandments: “Thou shalt not kill.”
“I knew it was wrong. As I was doing it I knew it was wrong,” he said.
But, during a four-hour interview, he sought to explain how worries that financial hardship would split his family and turn them away from their faith forced him to make a tough decision. “I finally decided the only way to save them from that was to kill them,” he said.
John List died in prison in 2008 at age 82, still believing he had done the right thing. The mansion where he committed his crimes was long gone, reduced to ashes under mysterious circumstances. But in Westfield, the memory of that November morning remains as vivid as the bloodstains that once marked the ballroom floor at Breeze Knoll.
To this day, children still cross the street rather than walk past the property. Some nightmares, it seems, never truly fade.
