Deadly Women is a television series first aired in 2005 on the Discovery Channel, focusing on female killers. It was originally a mini-series consisting of three episodes: "Obsession," "Greed" and "Revenge". After a 2-year hiatus, the show resumed production in 2008 and began airing on the Investigation Discovery channel as a regularly scheduled series. The 2008–present TV series is produced in Australia by Beyond International.
Each episode deals with three stories (four in each of the three mini-series episodes) centered around the theme of each episode, through re-enactments, The stories are narrated by Lynnanne Zager (Marsha Crenshaw in the mini-series). Surviving family and friends of the deceased (and of the killers' family and friends, occasionally), reporters and authors who dealt with the story, and the law enforcement officials involved (police, district attorneys) augment the narration. Subject-matter experts (SMEs), such as former FBI criminal profiler Candice DeLong and former Hennepin County (Minnesota) Medical Examiner Janis Amatuzio, add perspective to each story from their areas of expertise.
