Mafia 96. Curse of the Tephos Residents

Overall, the situation isn't great. To win, we need to carry out many executions; there's no other way to get rid of the mafia (or the serial killer). HOWEVER, an executed player cannot be resurrected, unlike a killed player. Should we continue to investigate, wait for more information, and prolong the game to 10+ nights, or should we take a risk and execute someone? I wouldn't mind hanging some inactive player or Tox, but the chance of being wrong is 33%. What does everyone think about this?
