In a sequential display, how many photos must be shown?

• A. 6 (5 + suspect)
• B. 4
• C. 8
• D. 5

Answer: (A)

In a sequential display, photos are shown one at a time to the witness, and the lineup includes the suspect plus several fillers who resemble the suspect. The standard setup is six photos in total: five fillers and the suspect. This arrangement gives the witness enough comparison options while aiming to reduce bias and misidentifications that can occur if there are too few or too many choices. The other counts don’t align with common practice: four would provide too few fillers, eight is more than the typical minimum, and five would mean only four fillers plus the suspect, offering less comparative balance.
