Steven Avery's own lawyer says it's worthless—for now. She's referring to a potential bombshell: an alleged confession by a Wisconsin inmate who has reportedly claimed to be Teresa Halbach's true killer. Avery and nephew Brendan Dassey are serving life for the crime, which was the subject of the Making a Murderer docu-series on Netflix. Shawn Rech is directing what he describes as a sort of follow-up called Convicting a Murderer. He tells Newsweek the confession came during the filming process and that he has audio of it. "We haven't confirmed the legitimacy of the confession," Rech says, "but seeing as it was given by a notable convicted murderer from Wisconsin, we feel responsible to deliver any and all possible evidence to law enforcement and legal teams."
Avery's lawyer, Kathleen Zellner, tweeted this Monday night: "We received the handwritten confession on Saturday. It is worthless unless it is corroborated.#MakingAMurderer2 #WorkingOnIt #NotsoFast." NBC News reports Dassey's lawyer, Laura Nirider, also tweeted on the subject on Monday, writing, "We are aware of the alleged confession given by an inmate in Brendan’s case. Thanks to all for your messages." Newsweek reports that Zellner is set to file paperwork in connection with Avery's appeal on Oct. 4. (Read more Steven Avery stories.)
