Luz claims that a murderer who has not been prosecuted is still a murderer.
Murder is a crime, therefore a murderer is someone who is convicted of committing the crime of murder. One can only be convicted of a crime after being prosecuted, brought to trial and found to be gulity beyond reasonable doubt. So if someone has not even been prosecuted, s/he cannot be labelled a murderer.
Why do you post like this? Talking about legal technicalities. Who cares about them? If you murder someone, yes, you are a murderer, plain and simple, whether you get caught or not, tried or not.

Same if you stole from a shop unseen, you stole, therefore you are a thief. If you have an affair and cheat on your wife you are an adulterer. Etc etc Your argument that no crime can have been committed unless the committer was tried and found guilty, if that is what you are saying, is just plain silly and I wonder what the point is. people who resort to legal technicalities are normaly those who are either guilty or defend guilty people!
