The Sisco–Harkness Murders and Chandler’s Conviction
In 2002, Mike Sisco and Karen Harkness were shot to death in their Topeka, Kansas bedroom. Prosecutors focused on Dana Chandler, the husband’s ex-wife, who lived in Denver and had exchanged angry messages with Sisco. In 2011 Chandler was arrested on two counts of pre-meditated first-degree murder and, after a 2012 trial, received consecutive life sentences.
Background & Context
The case stalled after the original county prosecutor declined to file charges, citing a lack of evidence placing Chandler at the scene. A politically appointed prosecutor revived the effort, and CBS’s *48 Hours* aired a 2009 segment that re-hashed the case, prompting Chandler’s arrest. The documentary follows a six-year investigation by filmmaker Matthew Galkin and producer Josh Levine, who question the prosecutions and the role of media in shaping public perception.

Official Statements & Responses
Filmmaker Matthew Galkin argues that Chandler’s self-representation in the third trial was a self-destructive move that likely doomed her chance of freedom. Josh Levine notes that each successive trial presented less evidence, with deliberations shrinking from six days to ninety minutes. Joe Sexton criticizes the local press for aligning with prosecutors and points to the influence of *48 Hours* in shaping the narrative against Chandler.
Verbatim Quotes
- “Over the three prosecutions, the basic gameplan was, ‘Let’s make her as ugly and unpleasant as we can,’” — Joe Sexton
- “It’s the same evidence in each trial, actually even less because they start throwing things out,” — Josh Levine
Conflicting Reports & Gaps
The documentary presents an alternate-killer theory implicating Jeff Sutton, Harkness’s son-in-law, but concludes that this line of inquiry collapses under a longstanding legal dispute between Sutton and Keen Umbehr. No definitive forensic evidence linking Sutton to the crime is offered.
Why It Matters
*A Killer Story* underscores how prosecutorial tactics, media framing, and limited press access can converge to shape a criminal case’s outcome. The Umbehrs’ willingness to risk their family farm to fund Chandler’s defense illustrates the personal stakes when legal systems appear inflexible. The series invites reflection on the influence of true-crime television on public opinion and the potential for confirmation bias to affect juries and investigators.
