act 3. cant get into the murder tribunal

[F.O.A.M]

so this will be a bit spoiler ish as a post but i need help.

during the quest investigate the murders you find out that a dwarf in a red outfit is killing everyone, from this dwarf you are suppose to get a piece of paper that gives you the password for the tribunal door.

thing is as im playing evil dark urge i decided to kill all of the red dwarfs last victims so he just never showed up. i have gone back to everyone i have killed to see if he would randomly be there and he isnt, i have long rested and done the same thing again and still nothing.

im stuck as i dont know how to get the passcode because every "guide" on the quest goes the non killing route which seems to have no issues tied to it and since this is tied to orin and how to get to her i must have this password
