just use "Homicidal" for all murder types, that means we can erase:

Murderer (by having homicidal we can add *attempted* murder, a crime that the current "murderer" does not allow)

Mass Murderer

Spree-Killers (far too many just use it as a tag to add to "mass murderer")

Serial-Killers (too many use it in the wrong context)
