As for the murders, it seems that Morninga was killed by smokers, even two of them (Mabus and Fallen). There should probably be two pieces of evidence...
Vegtama most likely killed the 13th, because only he has the murder. Although, who knows, maybe he successfully redirected the death.
Therefore, Vistrita was killed by cylinders; they have pistols.
