How long should a show up occur in a crime scene response?

• A. Immediately
• B. 60 minutes after
• C. 20 minutes after the crime has occurred
• D. 2 hours after

Answer: (C)

Show-ups should be conducted promptly after a crime to maximize the reliability of witness identification. The idea is to present a suspect while memory of the incident is still fresh, which helps the witness recall details accurately and reduces memory decay or contamination from outside information. About twenty minutes after the event is a commonly cited window because it balances practicality—allowing officers to locate the suspect and secure the scene—with the need to keep memory vivid. Waiting much longer, such as sixty minutes or a couple of hours, increases the chance that memory fades or becomes distorted and that the suspect’s availability or the scene’s condition changes, making a reliable identification less likely. Conducting a show-up too soon can also be disruptive or biased if the scene isn’t ready or investigators haven’t properly documented the incident.
