A more thorough explanation:

Definition: Richard Roe is a made-up name used for a male person involved in a legal case when their real identity is unknown or being kept secret. It is often used as the second of two such parties, alongside John Doe.

Example: In a lawsuit, the plaintiff may name Richard Roe as a defendant if they are unsure of the person's true identity. For instance, if someone was injured in a hit-and-run accident and the driver fled the scene, the victim may sue "John Doe" and "Richard Roe" until the driver is identified.

Explanation: The example illustrates how Richard Roe is used as a placeholder name for a defendant whose identity is not yet known. By using this name, the plaintiff can still initiate legal proceedings and seek compensation for damages, even if they do not know the defendant's real name.
