I don't think Avery did it. There were 36 million reasons for the Manitowoc Sheriffs department to put him away or at least pressure him into settling, and it worked. I think most of his creepiness towards Halbach comes from the fact that he was a horny hillbilly that had been away from women for 18 years. She had been out there multiple times on jobs, she knew where she was going. If she legitimately felt threatened or in danger, she would've taken the right measures. I would like to know who was calling her phone regularly that was reportedly a nuisance, I'm sure the phone records were looked at.
The nephew had no clue what he was saying or the severity of the situation. After his first "confession", he asked if he would be back in time for 6th period because he had a project to turn in. While in prison, he asked his mom when he'd get out by April 10th because that's when Wrestlemania was on. Throughout the whole process, his version of things flip flopped constantly, and he showed no emotion. There is evidence left out of the documentary that says he came home with bleach stains on his pants and he told his mom that it was from helping Steven clean his garage, but again, it's almost as if he was just looking for attention. Same for his 14 year old cousin, I think they were just outcast kids thinking it was a chance for some attention when they said they knew things about the case.
The opened vile of blood with a hole in the cap bothers me. The prosecutor didn't seem to have any answer for why that'd been messed with. Colborn looked very uncomfortable when questioned about calling in the plates on his cell phone then stating what kind of vehicle it was 2 days before it was reportedly found. Lenk was caught lying under oath multiple times. I think the EDTA was a large blow to the defense, although that in itself had many questionable things.
The ex boyfriend showed little emotion, but knew where she would be, admittedly hacked into her voicemail (which had deleted recordings), and played the "concerned acquaintance" role well by making sure he was in front of cameras, leading the search, etc.. The roommate didn't report her missing for 3-4 days. Brendan's brother and stepdad seemed very shady and were hellbent on pointing the finger at Avery. Very few things put the guilt on Avery to me. He was smart enough to erase all traces of DNA or signs of struggle and whatnot in the trailer and garage, yet leave the vehicle sitting near the front of the salvage yard (he could've crushed it) and the key (which was a spare with only his DNA) laying on the floor? No.
