Making A Murderer lawyer writes a book about trial and says Steven Avery case is 'far from unique'

It's the mystery murder case with countless twists and turns that has had viewers on the edge of their seats throughout the hit Netflix series, Making A Murderer. But now convicted killer Steven Avery's defence lawyer, Jeremy Buting, is to write a book on the trial and his career.

The book will explore the "dysfunction" of the criminal justice system when released next year, The AP reports. It will also feature the hugely popular Making A Murderer series – in aid of shifting a few more copies off the shelves, no doubt.

"I think I have a lot to say that transcends the Avery case," Buting announced. "Issues that came up in the Steven Avery trial that a lot of people think are unique to that case... are far from unique and happen all too often."

Publishing company HarperCollins confirmed the news to The Associated Press, and divulged details of its deal with Buting, claiming the book will land in stores by 2017.

The narrative will be a first-person overview of the Avery murder trial, and although Buting's insight will be fascinating, he's not the first person to share their personal experiences of the controversial murder trial. Ken Kratz, former District Attorney of Calumet County, Wisconsin, who prosecuted Avery in the 2005 murder of Teresa Halbach, is also writing his own book.

The prosecutor has accused film-makers behind Making A Murderer of leaving out key pieces of evidence and manipulating the footage to cast doubt on Avery's conviction. Talking about his book in January, Kratz said: "I believe somebody needs to stand up for the cops, the courts, and the victim by telling the truth and setting forth the vast amount of evidence proving Avery's guilt beyond a shadow of a doubt," Rolling Stone reports.

Buting dismissed Kratz's problem with Making A Murderer, stating in a video on Rolling Stone. "Mr Kratz has complained that big portions of the state's case were left out of the documentary," Buting said. "First of all, that's not true; the majority of their arguments were presented. But there are also defence arguments and defence evidence that wasn't covered."

Buting and Dean Strang, another defence attorney on the Avery case, have arranged a speaking tour where they will host a Q&A session discussing the Netflix documentary series and the criminal justice system.

This isn't the first Avery-related story to make the headlines this week, with his other lawyer, Kathleen Zellner, causing a stir on Twitter by claiming she had evidence of a new alibi that could free the 53-year-old convict, who is serving life in prison. She wrote on the social media sharing site: "Cellphone tower records of SA & TH provide airtight alibi for him. She left property he didn't. #MakingAMurderer #UnmakingAMurderer."

The unexpected new claims could be key in the battle to get him bailed ahead of a retrial as the prosecution prepares to file its case against Avery on 11 March.
