"Take all the soil back with you," Li Xiang commanded the excavator operator at work.
This excavation of a Qing Dynasty tomb that uncovered bodies was indeed a major discovery. The case of four bodies was the largest seen in Shannan Province this year.
Jiang Yuan's demands for the crime scene investigation had risen to a new level; he now required all backfill soil to be taken away.
Li Xiang agreed wholeheartedly and followed through. The more meticulous the crime scene investigation, the better, and the Locard's exchange principle of investigation theory relies precisely on comprehensive inquiry. If minute traces and evidence at a crime scene were ignored, then the principle of exchange couldn't serve its purpose.
The corresponding criminal theory should then be transformed into a theory of minute traces—turning major traces into smaller ones, using the negligence and complacency of the investigation staff to escape detection and thus create the perfect crime!
