Making a Murderer Part 2 put the spotlight on Zellner as she attempted to exonerate Avery.
With the second part of Making a Murderer having debuted on Netflix earlier this year, there has been a renewed interest in Steven Avery – the subject of the documentary.
Kathleen Zellner – Avery’s lawyer since 2016 – has revealed that she’s preparing a new 22,000 page document on the case that could potentially see Avery, who was convicted for the murder of Teresa Halbach in 2007, walk free.
Zellner said she aims to create a credible case for reasonable doubt by presenting an alternative theory that matches with the evidence her team has found.
