Which of the following is NOT a key objective of a crime scene investigator?

Crime scene investigators focus on collecting and preserving physical evidence, processing the scene, and documenting all findings to support an investigation. The primary objectives include recovering physical evidence, identifying the suspect or victim involved, and establishing facts that can substantiate witness claims based on the evidence collected.

While uncovering a motive can be important in the broader context of an investigation, it does not fall under the primary responsibilities of a crime scene investigator. Their role is more centered on the physical aspects of the scene rather than delving into psychological or circumstantial motivations behind the crime. The task of uncovering motive is typically explored by detectives and investigators after the crime scene evidence has been collected and analyzed.
