What may documentary evidence indicate about a suspect?

Documentary evidence can provide insight into the motives behind a suspect's actions by revealing patterns, relationships, or circumstances that may have influenced their behavior. For instance, documents such as emails, letters, or financial records can show a suspect's emotional state, personal relationships, or financial pressures that might have contributed to their criminal behavior. This type of evidence can be critical in understanding the context of a crime and helps investigators piece together the reasons that may have driven the suspect to commit unlawful acts.

In contrast, while documentary evidence may also provide information related to a suspect's educational background, criminal record, or travel history, it is not specifically intended to elucidate motives. Educational records reflect a person's qualifications, a criminal record highlights previous offenses but does not indicate reasons for actions, and travel history confirms movements. These elements are important but do not tie directly into understanding motive as effectively as documentary evidence can.
