Okay, I haven't looked through the clues, and to be honest, the way these narratives are written, I can't tell which murder is which...
First narrative: Serial killer kills a townie
Second narrative: Serial killer shoots the guy who just killed the townie in the shoulder. @________?
Yeah, my efforts to hide the identity of the various roles that got attacked tonight, caused me to merge the attacks together a bit. Sorry about that.
-Clues to the identity of the serial killer can be found when the villager is being attacked.
-Clues to the identity of the gunman(or the vigilante) can be found in the paragraph where he attacks the serial killer for the first time.
-Clues to the identity of the first hitman can be found when he attacks the gunman.
-Clues to the identity of the second hitman can be found in the paragraph where the bodyguard is pinning down the first hitman and the second one comes and attacks him from behind.
-The explosion in harks house is just fluff.
