Which document should be filed for a report of a stolen vehicle?

Filing a complaint of a stolen vehicle is the appropriate procedure because this document officially initiates a police investigation. It serves as the formal record indicating that a report has been made regarding the theft of a vehicle. The complaint of stolen vehicle will typically contain vital information such as the vehicle's make, model, identification number, and any distinguishing features, which are essential for law enforcement agencies to locate and recover the vehicle as well as for insurance purposes.

In contrast, options such as a field interview card are used to document interactions with individuals during police work but do not capture the complexities and details of a stolen vehicle incident. A desk journal might help document daily activities but is not a formal reporting mechanism for theft. An evidence tag is used to label and track physical evidence collected at a crime scene, which is not applicable in the initial reporting of a vehicle theft. Therefore, the complaint of stolen vehicle is the most relevant and crucial document for addressing this situation.
