As Kathleen Zellner launches what has become a very public defence of Steven Avery, she has revealed that she visited her client at the Waupun Correctional Institution in Wisconsin.
Netflix documentary series "Making a Murderer" stimulated a tidal wave of discussion in the news and online since its release late a year ago with viewers continuing to speculate whether the jailed Steven Avery was indeed the real killer.
In a rare interview with TheLipTV (other than social media, Zellner has been tight-lipped with press), she explained what compelled her to take the case, saying that she "intends to prove" who killed Teresa Halbach, and that it's "fairly obvious" who did it if you review the evidence in the criminal case.
She has spent several hours with Avery in prison and has collected DNA evidence in that time that she said will shed new light on the case.
The Chicago-based lawyer took over the case in January, joined by Tricia Bushnell of the Midwest Innocence Project, and has taken the case to Twitter, highlighting what she sees as major flaws in the prosecution's case.
It also told how, as he sued the Manitowoc County and its sheriff for $36m in damages for wrongful conviction, he was accused of the murder of a young photographer, Teresa Halbach.
The first of many tweets raises the inconsistencies of the forensic evidence: (note SA = Steven Avery, TH = Teresa Halbach). She added that Avery's case had "all of the hallmarks of a wrongful conviction case".
"Making a Murderer" subject Brendan Dassey's attorney, Laura Nirider, says that of the many things wrong with the police interrogation of her client, there's one overarching problem.
"There was a very poor investigation done of the victim's background, who she was involved with and circumstances of her life". The case of Halbach's killing emerged in 2005, when Avery's civil rights case was still pending.
