John Doe

In the United States, "John Doe" and "Jane Doe" became legal staples in cases where a person’s identity is unknown or needs protection. Courts often use these names when referring to unknown crime victims or defendants who are minors, protecting their identity in sensitive cases. Medical professionals similarly adopted "John Doe" and "Jane Doe" as stand-ins for unidentified patients, such as those who are unconscious, without identification, or deceased. This standardization simplifies records and documentation in complex or sensitive situations.
