Jane's father...¿?¿?
I've already seen the last episode of the 5th season. After 5 seasons, I don't rememeber if we now for sure that Jane's father is dead or alive. So, we don't know how old is his father, maybe he is not able to commit murders becasue of his age, but we also don't know if RJ is the one who kills or the one who commands to kill, actually our knonledge about RJ is quite poor. Perhaps Jane ruined his life running away. I thought in his father because it would be a surprise due to they never show him. In Twin Peaks the creators deciced who was the killer recording the "last" episode, and they say YOU, pointing with the finger. In fact, we can be victims of this action.....
