Man y'all need to stop with the "Amelia did it" shyt
If she did anything, she probably fukked up the investigation/public perception with her book.
Secondly, theres been nothing to indicate that Hayes did anything to his daughter other then neglect her. I also think its unlikely she's dead, because I don't think the family would lie in front of their kids.
two episodes in, Im pretty sure we know almost nothing about the crime. But we know a lot more about the theme and general tone, which can help us predict how the events will unfold. Hayes is a very passive and withdrawn character, kind of the opposite of Russ - he aint going to solve this case, and he may end up hurting it more then helping it. We've already seen him surrender - he talks about putting on the suit w/o question because 'he might be too chickenshyt', and we've also seen him allow the investigative team to put the doll clue on the news with minimal resistance.
I found it a lil off-putting that in the crucial deposition, the interviewers are the ones who possess new information, and not Hayes. Compare that with season 1, where the detectives are trying to find out what Russ knows, just going off of a vague copycat crime.
I also have a feeling the 1980 investigation is going to lead to an incredibly haphazard conviction. Which again contrasts season 1. Russ and Marty didn't get the yellow maninitially, but they got his posse. In season 3, I think we are going to see someone completely innocent become convicted.
