case closed
Investigation is over
Case closed signals that a matter is settled and requires no further discussion.
The phrase comes from legal and investigative contexts—when a case is closed, the file is shut and work stops.
It now serves as a conversational full stop: She admitted she was wrong. Case closed.
The tone can be triumphant, dismissive, or simply final.
