A documentary can reconstruct a trial, line up omissions, contradictions, and overlooked leads, but it cannot replace a jury. That is the boundary that A Killer Story, the new HBO docuseries focused on Dana Chandler, chooses not to cross. Journalist Joe Sexton, director Matthew Galkin, and producer Joshua Levine maintain that they have no evidence that would have led them to convict Chandler for the double murder of her ex-husband Mike Sisco and his new partner Karen Harkness. Yet, they do not claim that Chandler is innocent.
The distinction is substantial, especially in contemporary true crime, where audiovisual storytelling often tends to present itself as an appeal trial before the public. Instead, HBO brings to the screen a legal saga that remained on the fringes of national attention for years, preserving the divide between reasonable doubt over the strength of a conviction and certainty over who committed the crime.
The series premieres Thursday, September 10 on HBO and Max. At its center are the murders that took place in 2002 in Alma, Kansas, and a judicial journey that produced two convictions against Chandler across three trials—the third ending without a unanimous verdict. According to what emerged from the authors' reporting, the case lacked physical evidence. While that does not automatically erase the other elements weighed in court, it explains why the case has continued to raise questions.
From a stranger’s emails to a years-long investigation
The origins of A Killer Story were not a sudden discovery by the television production machine. It started with Eileen Umbehr, an Alma resident who in 2017 began writing repeatedly to Joe Sexton. Umbehr was convinced that Dana Chandler had been wrongfully convicted and was searching for someone willing to look into the case. Sexton, a senior editor at the New York Times and winner of five Pulitzers, initially ignored those messages; later, he decided to investigate.
From there came trips to the Midwest, years of on-the-ground reporting, and a series of articles and columns bylined by the journalist. Galkin's docuseries takes shape from that material and an already established relationship between Sexton and the community involved. This lineage matters: the project does not stem from exclusive access secured for television, but from a gradual journalistic investigation, later translated into a serialized format capable of highlighting characters, local rivalries, and developments in the story that would have carried a different weight on the page.
Galkin does not treat Sexton as a mere source or an invisible narrator. The journalist is a presence in the series, and his voice becomes part of its framework. The director, previously behind One Night in Idaho: The College Murders, describes him as a private eye figure out of noir fiction; Sexton attributes his direct, informal storytelling style to his upbringing in 1960s Brooklyn. For a reporter accustomed to print journalism, the transition to the camera required an adjustment, but HBO also seems to have built the series around this declared subjectivity.
The weight of an alternative suspect
One of the key turning points of the work involves Jeff Sutton, a lawyer identified in the series as a potential alternative suspect. Sexton and Levine had been working for some time to secure an interview with him; Sutton finally agreed to speak with Galkin once he became convinced that the journalist did not have a personal agenda against him. His participation provides the docuseries with a crucial narrative element, allowing it to explore a different lead without limiting it to third-party accounts.
It is also the most delicate passage. Presenting an alternative to the reconstruction that led to the convictions can help highlight flaws, unanswered questions, or perceived investigative missteps, but it is not equivalent to establishing criminal liability for another person. The creative team seems aware of this limitation: at times, Sutton may appear to be a plausible figure in the alternative theory put forward by the narrative, but the series is not presented as the definitive solution to the double homicide.
The same applies to Chandler. The creators' stance is neither an overturned verdict nor an act of acquittal. It is a position on the standard of proof they would have required before voting to convict. For a television production built around such a polarizing case, choosing this framing means relinquishing the simplest ending: one that hands the viewer an exonerated innocent or a new culprit to point the finger at.
True crime when it must also address its own responsibility
The crime documentary sector thrives on unsolved cases, legal controversies, and access to hard-to-reach subjects. But serialized storytelling, especially when it lands on platforms and channels with significant amplification power, alters the public afterlife of the cases it covers. An interview can reignite local debates; an alternative theory can quickly morph into a widespread belief online; the individuals involved become characters in a narrative aimed at an audience far broader than that of the original trial.
This is why A Killer Story occupies an intriguing space in the audiovisual industry. The docuseries' value does not rely solely on true-crime reporting, but on the authority of the names leading it and the decision to make the investigative methodology transparent: who sought the sources, for how long, what pushback they encountered, and where gray areas remain. Sexton's presence provides a journalistic backbone to a production that would otherwise risk being interpreted strictly through television true crime conventions.
This does not mean the format is neutral. Every series dictates pacing, points of view, and emotional intensity; even the sequence in which information is presented shapes the viewer's perception. The difference, in this case, lies in not mistaking the work of reconstruction for a definitive ruling. It is a less sensational approach than a documentary promising to “solve” the case, but one far more consistent with the complexity of an affair that has moved through three trials and two convictions.
For HBO and Max, the launch comes in a market where documentary series must distinguish themselves both through access to subjects and the quality of editorial mediation. A case little known to the general public can become relevant if the work can explain why its legal proceedings warrant attention without reducing the people involved to mere plot devices. Sutton's involvement and Sexton's explicit perspective provide the series with the tools to achieve this, but also increase the obligation to exercise the necessary caution.
The most immediate concrete consequence will be renewed public exposure for the Chandler case. Based on the available material, there is no way of knowing whether the docuseries will prompt judicial developments or formal proceedings. What it certainly will do is bring back to the fore a question the justice system has addressed multiple times, without its television portrayal being able to settle it: with the information known today, how sound was the decision to convict Dana Chandler? A Killer Story does not offer a definitive answer. It makes that lack of an answer, and the need to support it with verifiable facts, its most relevant element.
