What aspect of a victim's background may help reveal a suspect's motive?

A victim's social media activity can provide critical insights into their background and relationships, which may point toward a suspect's motive. Social media often reveals significant aspects of a person's life, including their affiliations, recent interactions, and emotional states. This information can indicate potential conflicts or motivations for someone to commit a crime against that individual. For instance, online disputes, public confrontations, or intimate relationships showcased on social media might illuminate reasons why a suspect would target a particular victim.

The other aspects, like a victim's favorite foods, hobbies, or clothing brand preferences, might not have the same direct relevance to uncovering a motive for a crime. While they can round out the understanding of a victim's personality or lifestyle, they don't typically offer the same level of insight into interpersonal conflicts or tensions that could lead to criminal behavior as social media activity does. Thus, examining social media is a more effective approach in linking a suspect's motive to the victim's background.
