Which factor is relevant to show-ups?

• A. Identity and age
• B. Time and place
• C. Vehicle color
• D. Weather conditions

Answer: (B)

Show-ups are most reliable when the suspect is presented to the witness as soon as possible after the event and in a location tied to the incident. Time and place matter because memory is freshest right after what happened, and presenting the suspect at or near the scene helps preserve the context in which observations were made. This reduces the chance that the witness’s identification is influenced by delays, separate experiences, or external cues, which can bias the result.

The other details describe the person or factors that can affect perception, but they don’t govern how the identification procedure should be conducted. Identity and age are attributes of the suspect, not the control point of the process. Vehicle color might aid recall but is not the key factor in the procedure. Weather conditions can influence perception, but they don’t determine the central requirement of presenting the suspect promptly at the scene to preserve reliability.
