In real, if a person is killed, the killer is unknown until the cops are on the investigation. This can also be apply ingame, where if a person is suddenly killed, the main chat will view:
[Player] has been murdered in [Location]
An icon will appear in the map, indicate the location of the murder. There are three possibilities:
1.
The police can use /solvecrime to solve it. The main chat will appear:
Officer [Police Officer Name] solved [Victim]'s murder. The killer [Murderer] is wanted.
2.
There are "clean kills" which cannot be solve. If a clean kill is committed, the main chat appear:
[Victim] has been found dead in [Location].
There are two conditions to make it a clean kill:
- No witnesses nearby (within a range)
- The victim has to be killed "naturally", Ex: Exploding, drowning,...
In this possibility, /solvecrime can't be used to discover the killer.
P/s : Sorry for the grammar and my stupidity to not knowing something is wrong in this idea.
