Michael Griesbach's "Indefensible: The Missing truth about Steven Avery, Teresa Halbach and Making a Murderer" reveals grim new details about Avery's violent past.

Griesbach reports how Avery previously experimented with bondage during his sexual relationships.

Avery also boasted how he wanted to rape and murder young women in a 'torture chamber, according to police reports citing his fellow inmates, known as "jailhouse snitches".

Prosecutors wanted to use these allegations in at his trial, but the judge deemed such information was inadmissible and unrelated to the killing of Miss Halbach.

Avery was jailed for 18 years after he was wrongly convicted of sexually assaulting a woman in 1985 in a case that sent shockwaves across America.

Griesbach, a Wisconsin prosecutor, helped exonerate Avery in 2003, but wrote his book detailing why he believes the 56-year-old is definitely guilty of killing Miss Halbach.

Revealing other shocking details of Avery's alleged crimes, Greisbach tells how Avery moved in with his then-girlfriend Jodi Stachowski shortly after his release.

But she was forced to call the police on him a few months after moving in together for a string of violent crimes against her.

PLANS FOR 'TORTURE CHAMBER'

Avery, 56, a controlling and manipulative boyfriend, found out Jodi was up North at the races, and forgot to mention to him that she was attending, consequently sparking fury from him.

After coming home at around 11pm, Jodi instantly experienced Avery at his worst.

An furious row kicked off between the two, with Jodi telling him to "pack up your s*** and move out".

This prompted Avery to push her, causing her to fall into a chair and hit her head, the book reveals.

In addition to that, prosecutor Griesbach says Avery then got on top of her, and continued hitting her, before threatening he should kill her.

She rushed to call 911 emergency services, but he reportedly ripped the phone out when he saw her attempting to call for help, according to police reports.

Before reaching the dispatcher, Avery strangled Jodi, making her lose consciousness, and then dragged her out to the car.

He then told her: "I should get the gun and kill you."

During prosecution, the jury had asked to hear about the couple's sexual habits, where Jodi revealed some personal details regarding their physical relationship.

She told investigators that Avery kept pornographic magazines and films all over the house, and the two would engage sexually every day.

While Avery was awaiting trial for the murder of Teresa Halbach in 2006, his niece stepped forward to reveal her truth about her uncle to Calumet County officer Wendy Balwin.

Avery's niece was 17 years old when he was released from jail in 2003, and she spent much time around him, she explained.

She said that in 2004, Avery kept asking to meet with her at supermarket Walmart, and recalled him "bragging about his money".

RAPED NIECE ON COUSIN'S BUNK BED

She also recalled him kissing her goodbye each time they would meet, and says she found it weird.

Avery's niece continued to recall her relationship with him, and said he would often tell her how her parents "hated" her, despite that being a lie.

She described his behaviour as "grooming", and began crying after explaining how her then-42-year-old uncle raped her on her cousin's bunk bed, the book reveals.

She also said that Avery kept telling her: "I'm gonna marry you someday when I get all my money, you'll see."

The girl told investigators at the time that Avery “forced” her to have sex with him telling her: “If you don't do this, I'm gonna hurt you; if you don't do this, I'm gonna set your house on fire.”

Avery, who is serving a life sentence for the slaughter of Teresa, was accused of sexually assaulting his niece who “remains emotionally scarred to this day”, according to Ken Kratz.

In 1985 Steven was falsely convicted of sexually assaulting a young female jogger.

It took 18 years for his conviction to be overturned and he was given a £28.2million payout in compensation.

Avery, who has always maintained his innocence, allegedly pushed her down on a bed, held her arms down and pulled her pants off - all while she was begging him to stop, the teen told police in 2004, according to transcripts seen by Sun Online.

Kratz, who has written a bombshell book about the case called Avery, has also hit out at the Netflix show’s producers - accusing them of “shamefully” omitting key evidence and presenting a one-sided view of the case.

Kratz said one of the biggest omissions of evidence in the show is that two witnesses saw Avery burning items in his burn barrel on October 31, 2005, the day Teresa was killed, and where her camera and phone were later found.

He says nothing in the 10-part second season - which has included in-depth crime scene recreations and expert testimony attempting to debunk the prosecution’s case - has made him question Avery’s guilt and believes there’s no way he’ll ever be freed.
