The convicted killer whose case was featured in the Netflix series Making A Murderer has filed a new appeal seeking his release.
Steven Avery, 53, claims authorities used an improper search warrant and said that any evidence found as a result “is clearly ’fruit of the poisonous tree”’.
Avery was convicted of first-degree intentional homicide in the death of photographer Teresa Halbach in Wisconsin a decade ago.
He had been wrongfully convicted years earlier in a rape case and served 18 years in prison before he was cleared by DNA evidence.
He was suing Manitowoc County for tens of millions of dollars when he and his nephew were arrested over Ms Halbach’s death.
Manitowoc County Sheriff Robert Hermann said he has not yet seen Avery’s appeal.
Sheriff Hermann previously said that the investigation into Avery’s case was proper.
