I assume you mean blood on the ice? Funny, thing i just rage quitted after not being able to accuse the right person. Good thing i saved way before i even entered Windhelm. Next ill just completely avoid that atrocious quest. Very bad poorly done filler content is what it is. They should have spent their time and resources on optimizing the game, than making all these other stupid broken filler quests.
Yeah haha, my sister can't even finish it, no second body and the butcher won't even say a word, and she's stuck with useless amulet. That quest is easy to break I hear, and it's a shame, I liked trying to catch a murderer, even if my character has to be a half witted twit who only can discover so many clues and a single accusation to accuse a "culprit". I would welcome a Sherlock feeling questline, but not one so terribly linear and broke, or over more important content, like the actual city itself. Priorities Bethesda, look up the definition
