MANITOWOC, WI -- The second part of the Netflix documentary "Making A Murderer" is rolling out on Friday, Oct. 19, 2018. Today, Netflix made public a three-minute trailer previewing the second part.

According to a WISN report Tuesday, the second part focuses on Kathleen Zellner's effort to prove the innocence of Steven Avery and his nephew, Brendan Dassey. They are both are serving life sentences for the murder of Teresa Halbach in 2005. Both maintain their innocence. People around the world became compulsive followers of the saga of convicted Manitowoc County killers Steven Avery and his nephew Brendan Dassey since "Making a Murderer" appeared on Netflix in December 2015.

Over the past two years, Downers Grove, Illinois, wrongful conviction attorney Kathleen Zellner took up Avery's case, vowing to prove that Avery was framed for the Halloween 2005 murder of Teresa Halbach and that the real killer was still at large.

"I have one goal, and that's to overturn the conviction of Steven Avery," Avery's attorney Kathleen Zellner is quoted in the trailer. "There's an abundance of evidence, this could flip the whole case."



In 2005, Dassey and his uncle, Steven Avery, were charged in Halbach's killing. She was shot twice in the head, and her bones and belongings were found burned in a barrel near Avery's trailer. Both Dassey and Avery were sentenced to life terms in 2007, convicted of first-degree intentional homicide, second-degree sexual assault, and mutilation of a corpse. Halbach, 25, was an aspiring photographer who was hired to take photographs for Auto Trader magazine when she disappeared.

Just 16 at the time of the murder, Dassey was convicted of helping his uncle, Steven Avery, cover up the crime in a case made famous by the Netflix documentary "Making a Murderer." Dassey was sentenced to life in prison with no possibility of parole for 41 years.

"Making a Murder" premiered on Nexflix in December 2015. The 10-episode series was filmed over a course of ten years. It covers the life of Avery as a worker at an auto salvage yard in Manitowoc. The series covers his role as well as covers the arrest, prosecution and conviction of Dassey in the murder of Halbach.
