Kathleen Zellner is continuing to work towards Steven Avery's appeal, and she's releasing new information whenever possible on her Twitter page.

Having taken on his case in January 2016, Avery's new attorney was quick to get to work. She started testing the evidence and the prosecution's theory of what happened to Teresa Halbach, which was presented in the 2005 trial that ultimately lead to her client's conviction.

This played out, in great detail, in the 10 new Making a Murderer episodes released to Netflix in October 2018.

Viewers watched as Zellner and her team of experts were unable to replicate the State's conclusions – most notably, relating to the blood and DNA evidence – undermining the case against Avery.

Some of the most shocking allegations were those made about Bobby Dassey; a star witness for the prosecution. He testified against Avery at trial but has since had his statement undermined by another witness – who happens to be his brother.

It was the contents of the Dassey family computer that really left people on edge, though. This evidence detailed disturbing and violent pornographic imagery that had been found, leaving many wondering whether or not any action would be taken on this basis alone.

In a new interview with Fox News, Zellner has hinted that this has, in fact, led to an investigation to explore these particular allegations.

"They started in November 2017 reinvestigating," the wrongful conviction lawyer said. "They were re-interviewing Bobby, they interviewed Scott Tadych twice. It appears to be an open investigation that they're at least looking at these claims.

"Then where we are procedurally is we're filing a brief with the appellate court Dec. 20, so we're just starting the appeal process with all of this new evidence."

It certainly seems like this won't be overlooked this time.

Speaking further about Bobby as a possible suspect, Zellner said: "We're trying to show motive, opportunity and a link to the crime, and we've presented an abundance of evidence..."

"We haven't changed our allegations," she later added. "If anything, we're continuing to investigate. We've developed more evidence... to support our allegations."

In Part 2 of Making a Murderer, we were told that Bryan Dassey had signed a statement to undermine Bobby's trial testimony. Bobby had asserted that he witnessed Teresa Halbach arrive on the Avery property, where he saw her taking photographs. He then claimed that he had seen Halbach "walking over" to Avery's trailer, and that he did not see her leave the property.

His brother Bryan has now called this into question. "I distinctly remember Bobby telling me, 'Steven could not have killed her because I saw her leave the property on October 31, 2005'," he said in a statement.

Zellner now alleges that she has three affidavits that work against Bobby.

Zellner explained that she had hold of a statement to say that "Bobby was the primary user of the computer and it was in his bedroom.

"Bryan said that Bobby lied at trial and said he didn't see Teresa leave the property, and he did see her leave and [Bobby] left immediately behind her.

"Then we have the half-brother Brad, who gave us an affidavit saying that Barb Dassey… told him that she'd hired someone to remove images. When we got the computer, finally got our hands on it… There'd been a huge number of images removed, but we had the underlying raw data, and that's how we were able to see all of the violent images," she claimed.

During a phone call featured in the documentary, Barb and her husband Scott both denied any involvement. Bobby, who was never treated as a suspect in the 2005 murder of Teresa Halbach, has also asserted his innocence.

With Making a Murderer 3 already being talked about, it seems that there's still a lot more to explore...

Making a Murderer Part 1 and Part 2 are now streaming on Netflix.
