In December 2015, Dassey's attorneys filed a writ of habeas corpus in federal district court for release or retrial, citing constitutional rights violations due to ineffective assistance of counsel and the coerced confession. In August 2016, Dassey's conviction was overturned by federal magistrate judge William E. Duffin, who ruled that his confession was involuntary. Duffin granted a defense petition for Dassey's release on November 14, but an appeals court overturned his ruling on November 17, ordering that Dassey remain incarcerated pending resolution of the state's appeal of the habeas decision.
On December 20, 2015, a petition was created at a White House petitioning site titled "Investigate and pardon the Averys in Wisconsin and punish the corrupt officials who railroaded these innocent men". In a January 2016 response to the petition, a White House spokesperson said that since Avery and Dassey "are both state prisoners, the President cannot pardon them. A pardon in this case would need to be issued at the state level by the appropriate authorities." A spokesman for Wisconsin governor Scott Walker stated that Walker had no plans to consider pardoning Avery.
On December 18, 2015, Netflix released Making a Murderer, a 10-episode original documentary series which explores Avery's and Dassey's investigations and trials. The documentary "examines allegations of police and prosecutorial misconduct, evidence tampering and witness coercion." The series was widely reviewed and discussed in the media. It generated numerous follow-up interviews and articles with parties shown in the documentary, including family members, and some reporters of the trials. A second season of the documentary was released via Netflix on October 19, 2018. In December 2018, Netflix and series producers were sued for defamation by Andrew Colborn, a former police officer for Manitowoc County who testified at Avery's murder trial. The suit alleges that the series omitted and distorted material in order to portray Colborn as a corrupt officer who planted evidence.
