So, yeah, the whole thing is completely bonkers.
Steven and Brendan both got convicted of the same crime, even though the 'evidence' used to convict Brendan directly contradicted that used against Steven. Brendan's 'confession' film is heartbreaking to watch - this low-IQ kid getting coerced into telling the cops exactly what they want to hear.
With Steven, there appears to be two conflicting stories - either he did it, or he didn't and the cops planted evidence to fit him up. Now, it seems pretty certain that the cops did plant evidence - the blood vial had been tampered with, it looks like the body had been burnt down by the quarry pit and then moved to the burn pit out at the back of the house. On this basis, the only verdict which could be returned would be not guilty, as there was way more than reasonable doubt.
However, there is a third possibility - that Steven did kill Teresa
and the police planted evidence (in the hope of making the case against him a lot tighter).
http://www.pajiba.com/netflix_movies_and_tv/is-steven-avery-guilty-evidence-making-a-murderer-didnt-present.phpThere's a lot of stuff there that didn't appear in the documentary.
- Steven always requested Teresa specifically came to do the Auto Trader photos - Teresa had complained about Steven in the past coming to meet her wearing only a towel.
- Steven't sweat DNA was found under the latch on the trunk of Teresa's car - seems improbable the police would be able to fabricate this.
Couple of other things about Steven's character - Brendan told his mum on the phone that Steven had abused him in the past. also, the conviction for animal cruelty that was mentioned in passing in the documentary was for dousing a live cat in petrol and throwing it on a fire. Now, animal cruelty when young is one of the biggest predictors of violent crime when older.
So it may not be as cut and dried as 'he was framed again'.
