Which method is used for suspect identification before a trial?

The correct identification method used before a trial is a show-up. A show-up involves presenting a single suspect to a witness shortly after a crime has occurred, often near the scene or shortly thereafter. This method is usually employed to quickly confirm or dismiss a suspect's involvement based on the witness's immediate recollection. The close temporal connection to the crime can enhance the reliability of the identification, as the events are freshly imprinted in the witness's memory.

In contrast to the show-up, other identification methods like photo line-ups and live line-ups involve multiple subjects for comparison. These can be effective but typically require more time and are not as immediate as a show-up. Witness recall refers to the witness’s ability to describe the crime and the suspect from memory, but it does not actively involve identifying a suspect from a group or single presentation, as is the case with the show-up method.
