Return to Manitowoc County: The State of Wisconsin vs. Steven A. Avery Dateline : Season 25 Episode 19

Wisconsin, 2017: Teresa Halbach, murdered in 2005, was the victim in the Netflix 10-part documentary Making a Murderer (MaM), which became a Netflix binge-watching phenomenon in 2015. Steven Avery and Brendan Dassey were convicted in 2007 to life in prison for the murder. This updates the case with surprising information not included in MaM. Lead investigator Tom Fassbender, who interrogated Dassey and some believe produced a false confession, is on camera for the first time defending his actions and the prosecution's evidence. He says Avery's blood found in Halbach's car didn't have EDTA in it so it's not planted. Ken Kratz, who wrote a book defending his view of the two as guilty, presents new circumstantial evidence. Avery's high-profile attorney Kathleen Zellner says she has new evidence to acquit Avery. The appeals status of Avery and Dassey are also presented.
