Yeah, that's a janitor kill. Body missing, one man dead, rest is flavour. Confirmed by the OP. Quaggas' ID will probably come up as a mafia claim somewhere down the line. Killing Quaggas n0 doesn't really hint towards strategy as he's not prone to inactivity and he's also not one of the obvious strong players. So I'm not getting much out of that line of thought unfort. If no reports come up our best shot is to take a look at one or two bandwagoneers from yesterday.
Probably something like Hitler, Genghis Khan, Stalin and Napoleon? They are described as 'conquerors' so they'd have to be a bit more successful than your average maniac.
lynch chewie Usually stays quiet and is difficult to get a read on which can be frustrating tstl. Is a good one to put some pressure on and force him to talk early IMO.
