Did I Miss Something? Spoiler

Olivia's father killed Quinn (supposedly) but was still given his bones. I thought it was he gets his bones or kills Quinn? So why would they give him what he wants after he already killed Quinn? Why is he able to walk around like nothing happened?

I thought Olivia had put a kill order out on him unless he let Quinn go? This I could see was a bluff but why wouldn't Jake or Olivia kill him after he killed Quinn? This show needs to end this season because they aren't even making sense anymore.

Why isn't everyone running around screaming that they will find out who killed her and why isn't it priority number 1 for the team to find her killer?
