Netflix documentary series Making a Murderer has turned fans into armchair investigators, typing furiously into Google to try and figure out what exactly happened in Manitowoc County over a span of two decades. One key character has been elusive since the series was released — namely, alleged murderer Steven Avery, who the series revolves around. Avery's prison is not facilitating interviews, which means news sources must write letters directly to Avery, who can then choose whether or not to add them to his list of allowed visitors. I'm assuming he's had an overwhelming amount of requests, but so far, he hasn't talked to the media. On Thursday, however, FOX6 received a letter from Avery, saying he would grant them an interview if the network investigated Manitowoc County Sheriff Robert Hermann. Crafty, Avery, very crafty.

FOX6 anchor and journalist Ted Perry wrote to Avery and eventually received a three-page-long reply. The first, handwritten by Avery, said he would grant Perry an interview if Fox agreed to investigate Hermann, the sheriff of the Manitowoc County Sheriff's Department that, according to many fans of Making a Murderer, framed Avery for Theresa Haibach's murder. When asked about the theory, Hermann told Romper, "Obviously that’s false. You get that feeling from the movie that there’s a corrupt Sheriff's office up in Manitowoc County, which is the wrong way to paint the case in the movie." It hasn't stopped the department from receiving hundreds of calls and emails related to the case.

The second page of Avery's letter to Fox was typed and referred to recent statements from Avery's former fiancee, Jodi Stachowski, who recently told TMZ and HLN that she was scared of Avery. "Steven's one person I don't trust. He's like Dr. Jekkyl and Mr. Hyde. A nice person or semi nice person. And behind closed doors, he's a monster," Stachowski told HLN. She said that she only spoke well of him in the documentary because she was threatened.

In his letter to Perry, Avery denied Stachowski's claims.

Threats against her and her family are totally untrue. Jodi must have been pressured by the state to change her story. She would never have said anything bad about me, due to the fact that she wanted to marry me. Why would Jodi now made accusations contrary to what she said on my 10-hour documentary unless Jodi was threatened in some way by the state of Wisconsin.

Avery has yet to see the Netflix documentary, as the service is not provided in prison and his requests to view the show have been denied, but Avery's sights have been set on bigger matters anyway. On Jan. 7, Avery filed an appeal with the Wisconsin Court of Appeals, citing abuse of a search warrant and jury improprieties, according to Business Insider. His previous appeals have been denied, but with international attention focused on his case due to Making a Murderer, this might be Avery's best chance at overturning his conviction.

The documentary also drew attention from The Innocence Project, and Illinois attorney Kathleen Zellner and her legal team took on Avery's case in early January, according to Yahoo! News. Zellner has been using Twitter to criticize his prosecution, drawing attention from Netflix fans who have followed the series' fallout.

Avery ended his letter to FOX on a hopeful note. "I am really innocent of this case, and that is the truth," he wrote. "This is from Steven A. Avery. The truth will set me free." No word yet from FOX on whether they will take Avery up on his interview-for-investigation trade, but I have a feeling both the investigation and the interview would be quite interesting if FOX chose to pursue Avery's offer.
