What should a Crime Scene Analyst (CSA) obtain upon arrival at a crime scene?

Upon arriving at a crime scene, it is vital for a Crime Scene Analyst to gather details from detectives, police officers, and witnesses. This information is pivotal as it provides context about the incident, helping to shape the investigation and guide the evidence collection process. Detectives and officers can offer insights about the sequence of events leading to the incident, potential motives, and any suspect information. Additionally, witnesses might provide critical firsthand accounts that can clarify the circumstances surrounding the crime, which can be crucial for reconstructing the incident accurately.

The other options do not prioritize immediate, relevant information critical for establishing the scene's context and understanding the crime. Interactions with federal agencies or reliance on previous crime reports may be useful later but are not the primary focus for a CSA upon arrival. Similarly, collecting the victim's personal information, while important for the investigation, does not provide immediate context about the crime scene and can be addressed as part of the larger investigative process once the scene has been assessed.
