Not surprised that Nickles was killed, could be one mafia team trying to take out what they thought was scum from the other team or Sparks deciding to finish the work he couldn't get done during the day. Hylian though, that is peculiar.
Also of note, neither Trucks nor prof were targeted. They both claim to be prime targets, scum from last game confirmed they were looking to take them out as quick as possible and yet, none of them targeted last night. Perhaps the call for protection from Trucks scared scum of that kill, but why was prof left to live?
