Forensics – Crime Scene Practice Test

In crime scene search methods, the key idea is to cover the area in a structured way so nothing is missed. A linear search does this by moving along straight, parallel lines across the scene, keeping a consistent distance between lines so each strip is examined. This creates a methodical sweep from one end to the other, which is why it’s described as proceeding in straight lines across the scene in a systematic way. It works well in long rooms, hallways, or open spaces where investigators can lay down clear, evenly spaced paths to ensure thorough coverage. Other patterns differ in motion: a spiral starts at a point and winds outward, not in straight lines; a grid uses crossing lines in two directions, forming a grid rather than a single straight-line sweep; and quadrant/zone searches divide the area into sections rather than sweeping across the whole scene in straight lines.
