Making A Murderer will return to Netflix with new episodes.
The original Emmy-nominated series explored the story of Steven Avery and his co-defendant Brendan Dassey as they were tried and convicted for the murder of 25-year-old photographer Teresa Halbach.
The new episodes, from creators Laura Ricciardi and Moira Demos, will follow "the high-stakes post-conviction process" as Steven and Brendan's legal teams attempt to overturn the killers' convictions and life sentences.
The popular documentary series has included claims the police framed Steven and Brendan for the 2005 murder in Manitowoc County, Wisconsin, by planting evidence and manipulating witnesses.
They will feature exclusive access to Steven's new lawyer Kathleen Zellner and Brendan's legal team, led by Laura Nirider and Steve Drizin, as well as intimate access to the families involved in the case.
Laura and Moira said: "We are extremely grateful for the tremendous response to, and support of, the series.
"The viewers' interest and attention has ensured that the story is not over, and we are fully committed to continuing to document events as they unfold."
Season one of the show earned six Emmy nominations including outstanding documentary or non-fiction series.
No date has been announced for the new series.
