Ten years after the brutal murder of Wisconsin native Teresa Halbach, her killer, Steven Avery, still maintains his innocence and insists that he had been framed.

Prior to his conviction for Halbach’s murder, Avery was charged with first-degree sexual assault and attempted murder of 36-year-old Penny Beerntsen in 1985. With the help of the Wisconsin Innocence Project and advancements in DNA testing, Avery was exonerated in 2003.

Because of the wrongful conviction that put him in jail for 18 years, Avery filed a $36 million lawsuit against the county, which sparked the creation of a criminal justice reforms bill named after him.

Two years later, 25-year-old professional photographer Teresa Halbach disappeared on the day she was set to meet Avery to take photos of his sister’s minivan for an ad in Auto Trader Magazine.  Avery was soon charged with Halbach’s murder after the police discovered her car and burnt remains at his salvage yard.

Avery has been vocal about his alleged innocence, claiming that his conviction was a deliberate retaliation of federal authorities for the case he had filed against them.

According to Halbach’s relatives, the filmmakers used an angle that suggests that the murder of Teresa Halbach was fabricated by authorities to frame Avery.

Avery’s former fiancée Jodi Stachowski denounced the innocent image in which Avery was portrayed, and revealed that he was violent and abusive towards her throughout their two-year relationship.

On the other hand, Avery’s mother Dolores believes that Teresa Halbach is still alive and that the charred remains were never really confirmed to be hers.

In a radio interview with TMZ, Dolores declared that Teresa Halbach might be involved in a conspiracy against her son.
