A Killer Story

2026SeriesMatthew Galkin

A contested case becomes a story about true crime itself

A Killer Story examines the 2002 deaths of Mike Sisco and Karen Harkness and the long-running case against Sisco's former wife, Dana Chandler. Directed by Matthew Galkin, the Story Syndicate production follows a case that drew attention for more than two decades. Its story includes both the prosecution and the people who came to question the conviction.

Kansas residents Eileen and Keen Umbehr become citizen investigators, working with New York journalist Joe Sexton in an effort to establish Chandler's innocence. The series therefore follows an investigation into an investigation: the original case, the challenges raised against it and the influence of people outside the criminal-justice system.

Three chapters through a changing prosecution

Welcome to Topeka introduces Sexton after a conviction is overturned. Person of Interest follows a new lead proposed by the Umbehrs and a witness whose account strengthens the prosecution's position. The chapters track changing arguments rather than presenting every participant as agreeing on what happened.

A Dangerous Notion reaches another retrial after a hung jury, including Chandler's decision to represent herself. The programme's episode description distinguishes the finality of a verdict from certainty about truth. That tension makes the documentary as much a study of belief, advocacy and storytelling as a chronology of a murder prosecution.

Welcome to Topeka

True crime enthusiasts Eileen and Keen Umbehr enlist veteran journalist Joe Sexton to delve into the case of Dana Chandler, who was arrested and convicted for the 2002 murders of her ex-husband and his girlfriend. The case is defined by the clichéd narrative of the jealous and vengeful ex-wife. Chandler's conviction is overturned on appeal with the help of the Umbehrs.

Person of Interest

During the retrial, the Umbehrs continue to defend Chandler's innocence by pointing to a person of interest who they believe to be the true killer. Meanwhile, the prosecution continues to argue a motive existed. Clarity remains elusive, but a surprise witness shifts the case in the prosecution's favor.

S01 · E03

A Dangerous Notion

The retrial ends in a hung jury, leading the state to try Dana for a third time. In an unexpected move, Dana dismisses her legal team and chooses to represent herself. The legal verdict brings finality to the case, but not necessarily the truth.
