What is the procedure called where a suspect is shown to a witness individually for identification?

The procedure where a suspect is shown to a witness individually for identification is referred to as a "showup." This method involves presenting a single individual, who is a suspect in a crime, to a witness shortly after the incident has occurred. The primary goal of a showup is to establish whether the witness can recognize or identify that individual as the perpetrator of the crime.

Showups are often used due to their immediacy, as they take place soon after the event, which can help improve the reliability of the witness's identification. In contrast, photo lineups and live lineups involve multiple individuals or images being presented at once, which can introduce different variables in the identification process. Additionally, in-person identification typically refers to any scenario where a suspect is identified in person, but it doesn't specifically capture the distinctive features of the showup process where only one suspect is presented to a witness.
