Murderers should remain grey to the person reporting, regardless of murder count number, until the victim decides otherwise. Kinda stupid that a player can be killed, go to a town priest nearby, re-gear to "go get some revenge"....only to find out they can't because the murderer is already blue and in town with your spoils.
Adding something like targeting the "killer" and typing /forgive will reset the flag.
