'Making a Murderer' subject Steven Avery files appeal

MILWAUKEE (AP) - A convicted killer who's the subject of the Netflix series "Making a Murderer" has filed an appeal saying authorities used an illegal warrant and that a juror was out to get him.

Steven Avery says evidence found on his property "is clearly 'FRUIT OF THE POISONOUS TREE'" and that a juror improperly influenced others.

Avery was convicted of first-degree intentional homicide in the death of photographer Teresa Halbach a decade ago. Avery had been wrongfully convicted years earlier in a rape case and served 18 years in prison. He had a lawsuit pending against Manitowoc County when he and his nephew were arrested in Halbach's death.

Manitowoc County Sheriff Robert Hermann says he hasn't seen Avery's appeal, which was filed Monday. He stands by the investigation.
