Common questions

What makes the fly-and-sickle case significant in forensic history?+

Song Ci describes a village official who identified a murder weapon by laying out all local sickles and observing which one attracted flies drawn to residual blood and tissue traces invisible to the eye, an early documented use of insect behavior as physical evidence in a criminal investigation.

Why is this text considered a landmark rather than just an old manual?+

It systematized practical death investigation methods, including how to examine wounds, distinguish drowning from strangulation, and use decomposition and insect activity as evidence, and it remained in official use across multiple East Asian judicial systems for centuries after it was written.
