I will say prior to watching this series, I had no prior knowledge to this case. If I were to just watch the news, and read stories in the paper, I would have thought Avery was absolutely guilty. After watching the series, I'm not convinced he's guilty by any means. There's a couple of alternative suspects that I'm shocked the police did not investigate further: -Bobby Dassey and the step father Scott. Considering they were their own eye witnesses saying they drove past each other near the Avery property around the time of the murder. Bobby said he was on the way hunting, so a nice story if he had a weapon on him. Both of them are also extremely passionate about putting Steven behind bars for good. -Teresa's ex boyfriend: That dude's story is quite suspicious to me. One of his "friends" was living with Teresa at the time, and he was okay with it? I don't think so. He also had the story that he "guessed" her user name and password to access her phone. Once he hacked it, those voice mails after she was murdered disappeared. I would be willing to bet that's not his first time accessing her accounts without her knowledge. -Unknown suspect. Teresa was a well known and liked person from the perception of her in the series. Someone else could have committed this murder, and disposed of her body on the Avery property. What I think happened: Teresa was blocked in leaving the Avery property, and forced into seclusion where she was murdered. Her body was transported in a barrel to the Avery property. The police convinces themselves it was Avery who did it, and Detectives made sure the proper evidence was placed in order to get him behind bars.
