As much as I can totally see that Jew framing the nog, there is a lot of doubt. I could see it going either way: Frank got Conley to help him clean up the murder or Conley himself did it.
Admittedly, I don't remember much about the case. What say you all?
EDIT: This makes me think Conley really did do it and the Jew was innocent:
