When should a lineup be considered in a follow-up investigation?

• A. When a showup is not possible
• B. Only if the suspect is not apprehended
• C. After gathering sufficient evidence
• D. When witnesses express uncertainty

Answer: (A)

A lineup should be considered in a follow-up investigation when a showup is not possible because lineups are typically conducted to allow multiple witnesses to view and identify a suspect among a group of individuals. A showup, which involves presenting a single suspect to a witness shortly after a crime has occurred, is preferred in some instances, particularly when the suspect is in custody and the timing is crucial for accurate identification. However, if a showup cannot be executed—due to the suspect being unavailable or other logistical issues—a lineup becomes a vital method for witness identification. This process helps in ensuring that the identification is fair and reduces the risk of misidentification, which is crucial for maintaining the integrity of the investigation. Other circumstances outlined in the options, such as the apprehension of the suspect or the need for sufficient evidence, do not directly dictate the necessity of a lineup. Additionally, while the uncertainty expressed by witnesses is relevant, it is not a primary reason for deciding to conduct a lineup over other identification procedures.
