Song court develops forensic investigation methods
1131
Magistrates in the Southern Song judiciary continued to refine practical techniques for examining suspicious deaths - testing for poison with silver needles heated over flame, mapping wound patterns on body diagrams, and distinguishing death by drowning from strangulation by examining the lungs. These methods, later codified in the landmark text Washing Away of Wrongs, constituted the world's first systematic approach to forensic science.
