What kind of observations should an investigator make at a crime scene?

An investigator should make a broad range of observations at a crime scene, which includes assessing the surroundings and context of the location. Focusing on questions about location, weather, and disturbances is essential as these factors can significantly influence the investigation. For instance, the weather might affect the preservation of evidence, while disturbances could indicate other activities that occurred near the crime scene, providing critical context for understanding events leading up to or following the crime.

Observations related to location help to map out where the crime occurred, identify any potential exit routes for suspects, and establish the crime scene's parameters. Weather conditions can also inform the investigation regarding evidence collection and analysis. Furthermore, noting disturbances, such as crowds or nearby events, can lead to additional witnesses or insights into the incident, making these observations invaluable for constructing a thorough narrative of events surrounding the crime.
