______ is the aspect of a robbery that may help in tying a person or group to a series of robberies.

• A. Ambush
• B. Planned operation
• C. Dry runs
• D. Signature

Answer: (D)

The idea being tested is that a robber’s signature—the distinctive, personal touches they leave at the scene—is what can link a person or group to a series of robberies. A signature reflects the offender’s unique style or ritual and is repeated across crimes, making it a strong clue for tying separate incidents to the same perpetrator. This is different from elements like ambush, planned operation, or dry runs, which describe how the crime is carried out or prepared but don’t necessarily reveal a consistent, personal imprint across cases. For example, a repeated phrase, a specific way money is counted, or a ritualistic action left at each scene can serve as that linking signature.
