Our Making a Murderer binge-watch may seem like yonks ago now, but developments are still coming in thick and fast from Steven Avery's post-conviction lawyer.
Kathleen Zellner became a world-famous name thanks to her no-nonsense approach to the case featured in the viral Netflix true-crime series, so it's hardly surprising that fans are still wanting to know what's happening in the ongoing appeals process.

In December 2018, two months after the second instalment of the documentary series was released, Zellner announced a fresh development in the Avery case.
The attorney revealed that she had enlisted the help of one of the "world's leading DNA experts" Dr Richard Selden, who agreed to "test the bones in the Manitowoc County Gravel Pit", should the court allow it. Zellner had filed a motion "asking the Appellate Court to remand the case for this testing to take place".
This could have been significant, according to Zellner, because the "State fought [the] idea of [Teresa Halbach] bones" being in the Manitowoc County Gravel Pit.

One of Avery's original defence lawyers Jerome Buting also said that Ken Kratz claimed the bones in the gravel pit "weren't human", and so it "would refute State's theory she was killed & burned in SA burn pit [sic]" if they were found to be.
However, this question will remain unanswered, at least for now, as the request has been denied by the Wisconsin Court of Appeals.
But, according to Zellner, this certainly doesn't mean that it's the end of the road for Avery. In fact, she says that the DNA testing may still happen, if necessary to the case, but that the court wants to resolve some of the other questions raised in Avery's appeal first.
"The appellate court wants to resolve the issues on Avery's current appeal before the new issue re: bone testing is addressed," she told Newsweek. "The state claims if Avery wins appeal, bone testing may become unnecessary."
Kathleen Zellner's own investigation into the original case – much of which featured in Making a Murderer 2 – has thrown up all sorts of new questions and theories.
"The bottom line is that the appellate court is not preventing Avery from doing the bone testing after the appeal is completed or by agreement with the new attorney general while the appeal is pending," she continued. "Either way, the court's decision does not damage Mr Avery's efforts to have his conviction vacated."
Zellner later demonstrated her perseverance on Twitter, telling her followers: "Steven Avery's fight for freedom is never going to end. Every new DNA test, new witness, new case just fuels the effort.
"We'll create the biggest court record in America if necessary to free him... just warming up for 2019."
Making a Murderer Part 1 and Part 2 are now streaming on Netflix.
