"Making a Murderer" told the story of Mr Avery, a Wisconsin man, who, having served 18 years in prison for a sexual assault, was exonerated for that crime.
After his release in 2003, Avery was charged in 2005 and convicted in 2007 of the murder of a woman, Teresa Halbach. Avery's nephew Dassey was also convicted as an accessory in that murder.
Over 10 episodes, the first season of "Making a Murderer" visited Avery's life. The documentary raised questions about the fairness of the investigation, Dassey's interrogation and his and Avery's trials, reported the New York Times.
Now Ricciardi and Demos are bringing fresh episodes that will "provide an in-depth look at the high-stakes post-conviction process, as well as, the emotional toll the process takes on all involved.
