A new theory has emerged about the killer of Teresa Halbach as documented in Making A Murderer.
A detective has come-up with the proposal that serial killer Edward Edwards was responsible for the murder and framed Steven Avery.
Edwards, who died in jail on April 7, 2011, killed at least five people.
But before these killings he was on the FBI's Ten Most Wanted list following a prison escape.
Retired detective John Cameron believes he killed Halbach 12 years ago.
He revealed: "What it turns out Edwards would do is he would create horrific murders that were in the press constantly that created terror, and he would set people up.
"It was always about the setup. Starting at a very young age, when he was 12 years old, he was able to set up a guy for a murder he had done.
"And for the rest of his life, he would get off on not only killing people but then setting up someone close to the victim and then watching the system execute them.
"Just before Edwards came to Great Falls, MT, in 1956, he set up a guy in Berkeley, CA, exactly like he set up Steve Avery."
Cameron revealed how Edwards committed multiple murders on Halloween night, and Halbach went missing on Oct. 31 while the detective also claimed Edwards lived just an hour away from Avery in 2005 when the murder took place.
Bizarrely it is also claimed that Edwards reportedly visited the trials of the people he framed and can even be seen in the background of footage shown in the sixth episode of Making a Murderer.
Edwards has also been linked to the infamous and unsolved Zodiac Killings – while Avery is currently serving a life sentence without the possibility of parole.
