HBO ~~announced the premiere of~~ has released ‘A Killer Story’, a three-part true crime documentary series directed by Matthew Galkin. The series, ~~scheduled for release~~ which premiered on September 10, 2026, examines a 2002 double-murder case in Topeka, Kansas, involving Dana Chandler, who was accused of killing her former husband, Mike Sisco, and his girlfriend, Karen Harkness. The victims were found shot multiple times in their home, though no weapon, DNA, or fingerprints were ever recovered, and valuables remained untouched. The documentary follows Pulitzer Prize-winning journalist Joe Sexton’s investigation into the case, which was prompted by extensive correspondence from Eileen and Keen Umbehr, who advocated for Chandler’s innocence. The Umbehrs, described as amateur sleuths with no direct connection to the victims or Chandler, have spent years pursuing what they claim is a ‘grave injustice’ based on skepticism regarding the circumstantial evidence used by prosecutors. The narrative explores the legal complexities of the case, including Chandler’s arrest in 2011 and her 2012 conviction for premeditated first-degree murder. Her legal battles have continued through an overturned conviction in 2018 due to prosecutorial misconduct, a hung jury in 2022, and a subsequent 2025 trial where Chandler was found guilty and sentenced to life in prison. ~~Key themes of the production include prosecutorial misconduct, confirmation bias, and the lack of forensic evidence~~ The series notes that in ~~the original investigation.~~ this final trial, Chandler chose to represent herself.
