A systematic methodology for examining residual evidence and patterns to reconstruct processes, behaviors, or events.

Trace Analysis

Trace analysis is a fundamental investigative approach that involves the systematic examination and interpretation of residual evidence to understand past events, processes, or behaviors. This methodology spans multiple disciplines and relies on the principle that every action or process leaves behind detectable traces.
