Kathleen Zellner has not been shy when it comes to talking about Stephen Avery’s case since season two of Making A Murderer aired on Netflix.
The hit Netflix series returned earlier this year covering updates in Avery’s case as Zellner tries to overturn his conviction.
She took on his cas after his conviction in 2007.
Zellner has since spoken about where it all went wrong in the 2007 trial for Avery, now 56, where he was given a life sentence for the murder of Teresa Halbach without possibility of parole.
Avery was given an additional five years for the illegal possession of a firearm by a Wisconsin jury, as seen in Netflix’s Making a Murderer.
Brenda Dassey, Avery’s nephew, was also given a life sentence, but his earliest date for parole is 2048.
Zellner said there was "ineffective counsel" in the original trial, and his reputation for being a "juvenile delinquent" when young had worked against him.
She also said Special Prosecutor Ken Kratz had a role to play – as she claimed he concealed evidence from the defence team.

Zellner put forward an alternative murder suspect, Bobby Dassey, Brenda’s brother, who was a witness for the prosecution.
She also claimed someone removed Avery’s blood from his sink and planted it in Teresa Halbach’s car – and this person was the killer.
Now she says she believes Avery will get out.
Speaking to the Daily Star she said: “I am [confident he will be released] because we really haven’t had the setbacks in this case that we’ve had in other cases where we’ve ultimately prevailed. So the name of this game of post-conviction is who is the most persistent?"
Zellner has highlighted three pieces of evidence she now feels should be tested by her own experts.
If they are tested she says they could finally crack the case.
Halbach’s Rav4 Jeep parking light
The first is Halbach’s Rav4 Jeep’s parking light. She said it had "smudges on" that she claims are either "paint or it’s a deer’s blood" or "something that could tell us more."
But she wants it DNA tested.

Zellner has her own team of experts
Rear cargo door on the vehicle
She said the blood on the rear cargo door was not deemed enough to complete a DNA profile. That was 13 years ago, and now Zellner says it was male blood that ruled Avery out in the trail. The full profile couldn’t have been developed at the time.
"But we can do that now," she says.
Hair found in the car
The last item is hair found in the vehicle, which was never tested as well as the license plates that were removed.
They have male DNA on them but they weren’t fully tested, she added.
Zellner is committed to getting Avery out and thinks by having all three fully tested could finally blow the case open wide.
- Making A Murderer: NEW evidence ‘proves Steven Avery’s innocence’
Viewers of the Netflix hit Making a Murderer labelled her the hero of the second series because of her steely determination and drive.
Zellner admitted it’s a commitment to unmasking the truth that motivates her, but she praised Avery for his “incredible resiliency” that keeps him going.
Avery was in prison for 18 years before before he was "saved’ by a single hair fragment.
He was falsely imprisoned for rape and attempted murder of Penny Beernsten – then released 18 years later after new DNA exonerated him.
