[KDC2] Help needed about a frustrating situation

So, I've just arrived at Kuttenberg. Unfortunately, I'm very poor. So I had the bright idea of killing the blacksmith, taking his key and robbing the armorer during the night.

Yet, when morning comes, I’m always getting arrested. Why? When I robbed the armorer, I spared no one and killed them all in their sleep, so there were no witnesses.

Any help would be appreciated.

edit: Going to the bath after my slaughter fix my problem. Now, I can steal more. Thank you all!
