Dark pigmentation, coagulation, some places burned some not. Whether the person after burn is alive or dead. Types of burn injury and what causes them: Thermal burns accidental, explosion, flame, hot liquids, contact with hot surface. Chemical burns acids, alkali substances: thrown acid crime, spilled acid accident. Forensic first step determines the source of the burn.
