It is possibly the most famous true-crime documentary in the world, Netflix original Making a Murderer has captivated millions of viewers with its complex twists and turns, since it was released three years ago.
The first series told the story of Steven Avery, who in 1985 was wrongfully convicted for sexual assault and after spending 18 years behind bars was eventually released in 2003.

It also looks into his later conviction for the murder of photographer Teresa Halbach in 2007.
Avery's nephew, Brendan Dassey, who has learning difficulties, is also convicted in connection to the murder, based primarily on a confession he made while under interrogation. Both men were sentenced to life in prison.
The second series, which was released earlier this year, introduces audiences to Kathleen Zellner, Avery's new lawyer who is working to get his conviction overturned.
And now according to the Zellner, she is going to file papers this month which could blow the case wide open, and which could become the subject of Making a Murderer season 3.

In fact, if the new evidence proves to be conclusive, it could prove the innocence of Steven Avery categorically.
Zellner sent the below tweets earlier on:
In the parlance of our times, HUGE. IF. TRUE.
She claims the files - made up of 22,000 pages - will be handed in on December 20 and contain new DNA evidence which could help free the former scrap metal worker, more than 10 years after he was put behind bars.

She told OK! magazine: "You must, if you can, create reasonable doubt by having an alternative theory that matches the evidence.
"That's when you're most likely to win a murder case."
She added: "The higher court is going to review all of this new evidence. After we file, the state will file their response, and then the court will have an oral argument, and then they'll make a decision.
"Whatever decision they make, it's going to go to the Wisconsin Supreme Court. So even if we win, the state will still force it to be decided by the highest court in Wisconsin."
The tenacious lawyer has a reputation for convincing judges to overturn cases - finding herself on the winning side 19 times in her career.

The 61-year-old says she is confident that she will be able to make it 20 and not only prove that Avery is innocent but that someone else is responsible.
She said: "I think another thing that goes on in these cases that people don't realise is that most murder cases, cold cases, end up being solved by witnesses finally coming forward.
"Someone else knows who committed this murder, and we are already getting tips about that. I believe - it's happened on several of my cases - that someone will come forward and say 'I know who committed the murder, they told me they committed the murder'. That's still in play."
She added: "My goal is to not just to find the constitutional violation to get Steven Avery a new trial, because many people are convicted again in their second trial. I am trying to get the evidence to what I believe is the truth of what happened, so that there won't BE another trial."
