for what i see there's only 2 rdm and we cant see if he left or not
the first he kill was a rdmer
the second that he almost kill was a rdm
the kill on zybra was because he try to kill the traitor who was the last guys unproven , and he the detective open fire on the first who shoot and was a rdm
for the leaving part we cant see it because only admin can see people joining/leaving
add a bind to status and dmg log , like tyber said already it's will help to know if he left or not or just a screenshot of the scoreboard
a bit late for a answer but , i'll request on lock because we cant prove he left and we cant ban him
