Upon arriving at the crime scene, the investigator met with Officer Sue who pointed out several areas of interest in the apartment. The investigator observed that the front door was open and lights were on, as was the condition upon the first officer's arrival. The investigator then performed specific tasks like taking photos, making diagrams and notes, and collecting evidence like fingerprints and analyzing blood spatter and bullet trajectories to be documented in a crime scene report detailing the what, when, where, who, and how of processing the scene.
