Forensic Science Capstone Practice Exam

The key idea here is the hands-on collection of tangible evidence. In this phase, investigators don’t just observe; they record what they see and physically gather items that could prove what happened. This means taking thorough documentation—photographs, notes, and sketches—to capture the scene as it exists, then carefully collecting objects with proper packaging, labeling, and handling to prevent contamination. Preserving the integrity of each item through chain of custody is essential so the evidence remains admissible for analysis in the lab. This focus on recording and retrieving physical items distinguishes it from initial scene work like surveying the area to plan searches, or steps that open or close access to the scene. It’s the dedicated collection effort that turns observed traces into evidence that can be examined microscopically, chemically, or statistically later on.
