Netflix’s ‘The Widower: ‘Til Death Do Us Part’ Release Date, Trailer, and What It’s About

Netflix is adding a new true crime title to its documentary slate, and this one traces a case that took nearly two decades to fully unravel. The Widower: ‘Til Death Do Us Part arrives on Netflix on September 30, 2026. The film joins a growing lineup of Netflix documentaries built around cases that took years, sometimes decades, to reach a courtroom.

The documentary is directed by Chris Smith and produced by Library Films and NBC News Studios. Smith is the filmmaker behind ‘Tiger King’, which gives the project a familiar creative hand for viewers who follow true crime programming closely.

The Widower ‘Til Death Do Us Part Release Date

The Widower: ‘Til Death Do Us Part becomes available to watch on Netflix starting September 30, 2026. Streaming trackers list the same date, so there is no confusion about when subscribers can press play.

The timing places the documentary squarely in Netflix’s fall true crime rotation, a period when the platform tends to lean heavily on real life criminal cases to draw viewers. The film joins Netflix’s true crime documentaries on September 30, 2026, and the investigation it covers unfolds over almost thirty years.

With a runtime of 1 hour and 31 minutes, the documentary is built as a single sitting watch rather than a multi part series, which sets it apart from some of Netflix’s longer true crime offerings.

The Widower ‘Til Death Do Us Part Trailer

Netflix released the official trailer for The Widower: ‘Til Death Do Us Part, and it opens with a disturbing clip of a 911 operator responding to an emergency call. Netflix dropped the trailer and key art on September 2, giving audiences nearly a month to see the story’s central conflict before the full documentary landed.

In the trailer, the man at the center of the case claims to be a victim rather than a murderer, while the investigators and the journalist involved describe him as someone who manipulated countless people around him. The journalist featured in the film notes that the case is one of the most bizarre and interesting he has ever dealt with, adding that the evidence and the husband’s own statements did not add up.

That clash between how the accused presents himself and how investigators view him appears to be the engine driving the entire film, built around a slow burn investigation into a pattern that went unnoticed for years.

What The Widower ‘Til Death Do Us Part Is About

In this documentary, a journalist and a detective uncover the truth about a killer whose charm masked a trail of failed marriages and suspicious deaths. The documentary is about a Las Vegas man, Thomas Randolph, who married six times, with four wives mysteriously dying.

The story began in 2008, when veteran Dateline NBC producer Dan Slepian was invited to accompany a Las Vegas homicide detective investigating the shooting deaths of Sharon Causse and Mike Miller. On May 8, 2008, Randolph told a Las Vegas Metro Police Department dispatcher that his wife had been shot and that there was a man in his house whom he had shot as well. Randolph, then 53, and Causse, 57, had returned home from a dinner out celebrating Mother’s Day about ten minutes before the shooting.

As Slepian worked alongside the detective on door knocks and interviews, filming much of it himself with a handheld camera, the pair learned that Randolph had been married six times and that four of his wives had died under mysterious circumstances, with Randolph receiving large life insurance payouts in two of those deaths. Colleen Beyer, Causse’s daughter, appears in the documentary as a reminder of the toll the case took on the family left behind.

The Real Case Behind The Widower

According to the Las Vegas Review-Journal, Thomas Randolph was arrested in January 2009, and it took over eight years for the case to go on trial. Thomas initially claimed that Causse was shot by an intruder in their Las Vegas home and said he killed the masked intruder in self defense.

In January 2009, Randolph was arrested for the killings of both Causse and a handyman named Mike Miller, whom he had allegedly hired to stage a robbery and orchestrate Causse’s murder. In 2017, Randolph was convicted of conspiracy to commit murder and two counts of murder with the use of a deadly weapon and was sentenced to death.

Randolph appealed, and the Nevada Supreme Court overturned his conviction and ordered a second trial. In 2023, he was found guilty of the same charges again, and in April 2024, he was sentenced to 60 years to life in prison. Slepian, who spent nearly 20 years following the case alongside the detective, called Randolph the most unusual murder defendant he has covered in his 30 year career as a journalist.

Between a nearly two decade investigation, two separate trials, and a pattern of suspicious deaths spanning multiple marriages, ‘The Widower: ‘Til Death Do Us Part’ sets up a viewing experience true crime audiences will likely be dissecting scene by scene once it lands on Netflix, and it will be worth hearing how viewers react once they’ve watched Thomas Randolph tell his side of the story on screen.
