Investigating A: Crime Scene Ielts Reading Answers

Once secured, the lead investigator conducts a initial walk-through. This is a critical, low-stress assessment where the investigator identifies potential hazards, notes transient evidence (such as odors, temperature, or dew on a body), and determines the most logical entry and exit path. Only after this preliminary survey does the systematic documentation begin. Photography takes precedence over sketching and note-taking because cameras capture the scene’s unaltered condition.

Trace evidence—fibers, hair, glass fragments—is lifted using adhesive tape or collected with a vacuum device fitted with a filter. DNA-rich sources like blood or saliva are allowed to air-dry before being packaged in paper bags (never plastic, as plastic traps moisture and promotes bacterial growth, which degrades DNA). Fingerprints are developed using powders, vapors (cyanoacrylate, or superglue fuming), or chemical reagents like ninhydrin. Each item is sealed in a separate container, labeled, and signed.
