I want to turn a murder mystery into a real thing
Unfortunately, this is not possible. However, if you still want to investigate a "murder" you can always try staging your own crime scene and seeing if you can figure out who did it!
You could host a murder mystery dinner party to make a mystery out of the situation. Invite some friends and set up clues around the house in preparation for a night of solving a fictional crime. After all of the clues have been revealed and all the guests are gathered together, you can reveal the identity of the person responsible for the murder.
