Without the ability to use that confession, it is doubtful the state has sufficient evidence to bring charges against Dassey for the death of Teressa Halbach. The petition is meant to request a federal judge to investigate the legality of Dassey's arrest and conviction.
Brendan Dassey, whose confession to involvement in the murder of Teresa Halbach was depicted in the wildly popular Netflix documentary series "Making a Murderer", may be released from prison by Thanksgiving.
Stating that she was thrilled for Dassey as a result of the fact that the State of Wisconsin "willfully destroyed his life", she warned that she believes that Avery is "capable of murder".
On Friday, a federal judge ruled investigators made false promises and took advantage of Dassey's age and intellectual deficiencies to unfairly coerce a confession.
Earl Avery says he doesn't think Dassey will be retried because he has the support of some in the public. Prosecutors have 90 days to decide what to do now. Video footage clearly showed detectives asking leading questions, and misleading Dassey on key points.
Halbach was killed at the Avery Salvage Yard, where she had been hired to photograph vehicles for a magazine, according to court documents. On this point, Judge Duffin found almost all of the details Dassey provided in his confession could have been obtained from media sources or from the investigators themselves, feeding information to him. Two days later, he is charged with first degree murder, sexual assault, and corpse mutilation.
"This is right, this is justice", Laura Nirider told ABC News on Friday night. Duffin also noted that Dassey was a learning-disabled high school student at the time of his confession, and that investigators made promises of leniency to Dassey that were not kept. Tissue and bone fragments that matched Halbach's DNA profile were found outside Avery's mobile home. The judge found that confession was involuntary in a 91-page decision.
US Magistrate Judge William Duffin referred to Mr Kachinsky's representation as misconduct that was "indefensible". The then-teenager was pressured into giving a confession under controversial circumstances, and most viewers agreed that his case was terribly mishandled.
Steven Avery's lawyer Dean Strang - who was featured prominently in the documentary - welcomed the decision, telling the Huffington Post: "Our federal courts are often the last protectors of our liberties and justice".
