Netflix’s new seriesThe Watcherhas thrust Westfield, N.J., into the public eye. But decades before creepy letters began to arrive for the Broaddus family, a horrific crime involving a prominent Westfield family shook the idyllic suburb.

The Watcheris loosely based on the true story of the Brauddus family — who are renamed the Brannocks in the series — and the alarming letters they began to receive after purchasing the home at 657 Boulevard in 2014.

In the fictionalized series, Graff’s creepy character is the former owner of 657 Boulevard, who also receives letters from The Watcher and then kills his entire family.

In real life, List had no connection to 657 Boulevard, but he owned a mansion in Westfield and killed his wife, mother, and his three children before going on the run for nearly 18 years.

On November, 9, 1971, List sent his children to school, then got two old handguns from his garage. He went back inside his 19-room mansion — which was named Breeze Knoll — and shot and killed his wife of nearly 20 years, Helen List, in the kitchen. He then made his way to the third floor where his 84-year-old mother, Alma, lived in a converted apartment,NJ.com reports. After the pair greeted each other, he shot and killed her, too.

List dragged his wife’s body to the ballroom of the mansion, then went to the kitchen and mopped the floor. When he was finished, he made himself a sandwich and ate at the kitchen table while waiting for his children to arrive home.

After the killings, he lined his three children’s bodies up in the ballroom next to his wife on sleeping bags.

The List family.

Their bodies were discovered a month later once people began to get suspicious about the family’s absence. It took so long for people to notice because List sent letters to the children’s school saying they’d be gone for awhile to visit their ailing grandmother out of state.

When officers arrived at the mansion they discovered the bodies of the children and their mother in the ballroom. Then they found letters from List himself — including one written to his pastor in which he confessed to what he had done, NJ.com reports.

“I’m sure many will say how can anyone do such a horrible thing. My only answer is it isn’t easy and was only done after much thought,” the confession letter read in part.

Although detectives had a full confession, List was nowhere to be found — and he had almost a full month head start on detectives thanks to his months-long planning.

FBI agents arrived at the shared home of Delores and Robert Clark on June 1 and knocked on the door. Delores answered, but her husband was at work. One of the officers stayed with her while the other rushed to where he was working. John List was caught.

“He was a strange man, I would say,” FBI Agent Kevin August said of List, NJ.com reports. “He was not very animated — that’s the best way to put it. He seemed to me as a vessel, with no soul in there.”

On April 12, 1990, List was convicted of five counts of first-degree murder and was sentenced to life in prison.

During a2002 interview with Connie Chung, List expressed regret for the killings saying, “I wish I had never done what I did. I’ve regretted my actions and prayed for forgiveness ever since.”

“It was my belief that if you kill yourself, you won’t go to heaven,” he said during the interview. “So eventually I got to the point where I felt that I could kill them. Hopefully they would go to heaven, and then maybe I would have a chance to later confess my sins to God and get forgiveness.”

On March 21, 2008, List died at the age of 82 of complications from pneumonia, but the infamous story of the List murders still haunts Westfield.
