I agree that ReZ is shifty but we can't ignore the fact that if he's mafia he would've been roleblocked last night. This only leaves Jimbob as the person who could have killed. Everyone else's actions are accounted for. We can see Mr-Paul highlighted Yvonne, Yvonne targeted me (rendering me roleblocked) and Sheikah caused Yvonne confusion.
This leaves ReZ and Jimbob. If ReZ is mafia he would've been roleblocked last night (by my ability) so Jimbob must've killed.
Vote: Jimbob
