4. Sung-tsu – the Father of Forensic Science
Ideally, intuition and science come together as complementary processes. Gil Grissom, lead investigator of the CSI television series, offers a case in point, when he talks about an incident that supposedly occurred in ancient China. A group of men were laboring in a ditch when one worker killed another with some implement. No one would confess to the crime, and the questioning of witnesses turned up nothing, so the magistrate ordered the men of the village to gather with their sickles. In time, the flies came, attracted to blood and specks of flesh, and the killer was revealed. The killer confessed.

5. Not long ago identifying, capturing, and convicting criminals depended primarily upon eyewitnesses and confessions. The world was a small place.
Every forensic technique is designed to either identify a perpetrator or connect him or her to the crime.
