MILWAUKEE (AP) — A convicted killer who is the subject of the Netflix series "Making a Murderer" filed a wide-ranging appeal claiming authorities used an improper warrant and that a juror was out to get him, among other things.

 Steven Avery, who's seeking to be released on bond, 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 sued Manitowoc County for tens of millions before he and his nephew, Brendan Dassey, were arrested in Halbach's death. 
 
 The appeal, filed Monday in an appeals court in Madison, bears Avery's signature and contains numerous spelling and grammar errors. His new attorney's name doesn't appear on it. 
 
 Manitowoc County Sheriff Robert Hermann said Tuesday he hasn't seen the appeal, but he has said in the past that the investigation was proper. 
 
 The filmmakers behind "Making a Murder" cast doubt on the legal process used to convict Avery and Dassey, and their work has sparked national interest and conjecture. Armchair investigators have flooded Twitter and message boards, and key players in the case have appeared on national news and talk shows. 
 
 Authorities involved in the case have called the 10-hour series biased. Filmmakers Laura Ricciardi and Moira Demos, meanwhile, have stood by their work. 
 
 Avery's new attorney, Kathleen Zellner, wasn't immediately available for comment Tuesday. 
 
 In the filing, Avery takes issue with a search conducted during the murder investigation, saying it improperly included multiple properties and therefore any evidence that was uncovered "is clearly 'FRUIT OF THE POISONOUS TREE.'" The appeal also says that a juror tainted other jurors "THROUGH DIRECT OR INDIRECT IN FLUENCE," stating numerous times that Avery "IS F------ GUILTY." 
 
 He also said Judge Angela W. Sutkiewicz made misleading statements and that his lawyers were ineffective.

 Steven Avery, the convicted killer featured in Netflix's "Making a Murderer," won't be pardoned if Wisconsin Gov. Scott Walker has anything to do about it. 
 
 Tens of thousands of people have signed petitions for Avery to be exonerated in the October 2005 killing of Teresa Halbach after the documentary suggested that Avery might have been a stooge for a conspiracy. 
 
 Avery, 53, insists he didn't kill Halbach, a 25-year-old freelance photographer. He is serving life in prison for murder, and Brendan Dassey, his nephew, who was a teenager at the time of the killing, is serving life as an accessory. 
 
 The White House has previously pointed out that President Barack Obama can't pardon Avery because he wasn't convicted of a federal crime.

 And Monday, Walker — a tough-on-crime Republican who has never issued a pardon during his five years in office — indicated in a statement posted to social media that he wouldn't start with Avery. 
 
 The statement links to an August 2011 decision by a three-judge panel of the Wisconsin Court of Appeals. The judges upheld Avery's conviction, ruling that the removal of a juror from his trial and the introduction of key evidence found in his home were proper. 
 
 Kathleen Zellner, an Illinois lawyer who specializes in seeking reversals of convictions, took over last week as head of Avery's defense. She said in a statement that the defense has uncovered new evidence that will exonerate Avery — but she didn't say what it was.
– Steven Avery has filed a fresh appeal in his Wisconsin murder case—and thanks to the hit Netflix documentary Making a Murderer, there are now a lot more people paying attention. The appeal filed in a Madison court on Monday, which can be seen in full here, accuses authorities of searching his property illegally and claims that a juror with a preconceived notion that he was guilty improperly influenced other jurors during his 2007 trial for the murder of Teresa Halbach, the AP reports. Avery recently secured new legal representation from Chicago-area lawyer Kathleen Zellner and the Midwest Innocence Project, reports WBAY, but Monday's court filing appears to have been prepared without the new legal team. Zellner specializes in reversing convictions, and she says she has found new evidence that will exonerate Avery, reports NBC News. The Netflix documentary suggests that Avery—who served 18 years for a rape he didn't commit before being released two years before the Halbach murder—is the victim of a conspiracy, and a petition urging President Obama and Gov. Scott Walker to free him now has more than 415,000 signatures. Walker, however, has never pardoned anybody, and WBAY reports that he has signaled he isn't going to start with Avery. Netflix viewers "should read the unanimous opinion of the Court of Appeals before jumping to conclusions," he said in a Facebook post.
