What action should be taken if identification is made in a photo lineup?

When an identification is made in a photo lineup, it is crucial to document the precise photo that the eyewitness identified. This is important for several reasons. First, maintaining accurate records of the identification helps to ensure the integrity of the investigation and supports any subsequent legal proceedings. Having a documented record establishes a clear connection between the eyewitness's testimony and the specific evidence presented, making it easier for law enforcement and the judicial system to understand the context of the identification.

Furthermore, accurate documentation can protect against potential legal challenges regarding the reliability or validity of the identification. By noting which photo was selected by the witness, investigators can also analyze patterns in eyewitness identification, which can inform future practices and improve the overall process.

The other options do not appropriately address the necessary steps following a positive identification in a photo lineup. Ignoring the identification disregards an important piece of evidence, alerting the media could compromise the investigation and affect the due process, while questioning the eyewitness, without appropriate context, could undermine the confidence in their identification, especially after it has been established through a structured process.
