Since no one wants to handle this, I shall take the role.
It is a staff report not an appeal, only SA+ can handle.
Anyways, when a user says they killed someone because they didn't id a body, we have to take their word on it. In this instance you should've really responded with just saying "you didn't id the body". You didn't really explain the situations the best. To be honest Stuny should've handled this a little better by opening a chat, but he was justified with what you said. Especially with your's and Stuny's history.
