A Murder Case That Went Through Three Trials

HBO’s new docuseries A Killer Story revisits the Dana Chandler murder case, a Kansas prosecution that stretched across more than two decades and included an overturned conviction, a hung jury and a third trial that ended with Chandler being convicted again.

Chandler was found guilty in 2025 of murdering her former husband, Mike Sisco, and his partner, Karen Harkness. The two were found dead in their Topeka home in July 2002, according to People.

The case now being examined on HBO is not an unresolved prosecution. Chandler is serving two consecutive life sentences, while continuing to challenge the case through legal filings.

The First Conviction Was Reversed

Chandler was arrested in 2011 and first tried in 2012. A jury convicted her of two counts of first-degree murder, and she received consecutive life sentences.

Six years later, the Kansas Supreme Court reversed those convictions because of prosecutorial misconduct. A later Kansas Supreme Court disciplinary opinion described false statements made by the lead prosecutor during the original trial and explained why the misconduct had become central to Chandler’s appeal.

The reversal did not dismiss the charges. Prosecutors were allowed to try Chandler again.

That second trial came in 2022 and ended without a verdict after jurors could not reach a unanimous decision.

A Third Jury Convicted Her in 2025

Chandler went to trial a third time in 2025. People reported that the trial was moved to Pottawatomie County and that Chandler represented herself.

The jury convicted her of first-degree murder in the deaths of Sisco and Harkness. She was later sentenced to two consecutive life terms with a minimum of 25 years on each before parole eligibility, according to People.

Chandler has maintained her innocence. Her position is one reason the case attracted the attention of Eileen and Keen Umbehr, a Kansas couple who became convinced that she had been wrongly convicted.

Their effort is central to HBO’s A Killer Story, which also follows journalist Joe Sexton as he examines the case and the claims being made about the evidence.

The Documentary Focuses on the Fight Over the Evidence

HBO describes the series as following an investigative journalist and two citizen sleuths pursuing the truth behind the 2002 double homicide.

People reported that the prosecution did not have DNA or fingerprints tying Chandler to the scene and that the murder weapon was never recovered. Prosecutors instead relied heavily on circumstantial evidence, including Chandler’s history with Sisco and activity surrounding her cellphone.

A documentary can raise questions about a conviction, but it does not replace the court record. Chandler’s 2012 convictions were overturned for prosecutorial misconduct; her 2022 retrial ended in a hung jury; and a new jury convicted her in 2025.

Those are separate legal stages, and each matters to understanding where the case stands now.

The Current Status Is a Conviction Under Appeal

Chandler is incarcerated in Kansas. People reported that she has continued filing motions and pursuing appellate options following the 2025 convictions.

The HBO series arrives after the third trial rather than before a final outcome. That gives viewers a complete sequence to examine: the original prosecution, the reversal, the failed retrial and the later conviction.

For this documentary test, the hook is not simply that HBO made a true-crime series. The underlying story is the unusual legal progression of a murder case that had to be tried three times before the current convictions were reached.

The documentary may renew debate around the evidence and Chandler’s innocence claims, but the factual starting point remains clear: two people were killed in 2002, Chandler was convicted in 2025 after two earlier trials failed to produce a lasting verdict, and her legal challenges continue.
