John Doe summons

A John Doe summons is a legal tool used by law enforcement or other authorities to obtain information about an unidentified person involved in a particular investigation. It allows them to issue a subpoena to a third party, like a bank or internet service provider, to disclose information related to that individual, such as account details or user activity. The "John Doe" designation refers to an unknown person, and this type of summons helps authorities gather evidence when the identity of a suspect is not yet known but is necessary for the investigation.
