In crime scene terminology, what does ‘motive’ refer to?

In crime scene terminology, ‘motive’ refers to a reason for committing the crime. Understanding motive is crucial in criminal investigations, as it helps to establish why a suspect may have engaged in a particular illegal act. Motives can vary widely and can include emotional factors, financial gain, revenge, or other personal reasons that drove an individual to commit the crime. Identifying the motive is essential for investigators, as it can lead to important evidence, help prioritize suspects, and provide context for the crime. Investigators often look for motives to build a narrative of the events leading up to the crime and to understand the motivations behind a suspect's actions.

The other choices pertain to different aspects of a crime investigation but do not define motive. An alibi relates to defending a suspect's whereabouts during the commission of the crime, the crime scene layout involves the spatial arrangement and evidence at the crime scene, and an investigator's strategy refers to planning and executing the investigation process. Each plays its part in solving a case, but none captures the essence of motive as directly as the concept of a reason for committing the crime does.
