Limelemon, I hate to say it, but he's another prime suspect, according to day two data.
As for Shawnachu FOS, I'm unfortunately without info, so someone had to be a prime suspect, and I think shawnachu could explain a bit on his work. As far as I know from surviving people, we definitely have a mafia, might have a protective role for the town, and we still have an investigative role.
Apologies about the slight mishap shawnachu, but my FOS changes to Limelemon.
