MANITOWOC COUNTY (NBC26) -- Steven Avery's attorney has filed new paperwork in court Monday, in the latest developments of the case that inspired the Making a Murderer Netflix series.
The 150-page appellate brief, filed in the Wisconsin Court of Appeals, argues the circuit court "abused its discretion" in denying Avery’s recent motions, including a motion to have evidence in his case undergo new scientific testing and his motions for post-conviction relief.
Steven Avery was convicted of multiple crimes, including first-degree intentional homicide, in the 2005 death of Halbach in Manitowoc County.
The controversial case and lengthy trial gained international attention when Netflix released Making a Murderer in 2015, a documentary that raised questions about the conviction of Avery and his nephew, Brendan Dassey.
Avery has been unsuccessful in multiple attempts to appeal his conviction.
