Debuts September 11
HBO Original Three-Part Documentary Series
A KILLER STORY
3 Episodes
Exclusively available to stream on HBO Max in the UK and Ireland
Rollout: Episodes debut weekly
Synopsis: A KILLER STORY examines a polarizing murder case that spanned more than two decades and captured national attention. At the center of the case is Dana Chandler, who was accused of killing her ex-husband and his girlfriend in 2002. Lacking forensic evidence, the murder case is litigated over three arduous trials with the series unspooling a complex tale of family conflicts, betrayal, prosecutorial misconduct, competing narratives and confirmation bias. More than a murder mystery, A KILLER STORY probes true crime obsession and the dangers of blinkered certainty in a case where the truth may never be known.
Featured Participants: Investigative journalist, Joe Sexton; true-crime advocates, Eileen and Keen Umbehr; witness, Terri Anderson; jurors; and others
Credits: HBO Documentary Films presents A KILLER STORY, a Story Syndicate production in association with Concordia Studio and Fairhaven.
