章 148: Chapter 144 Footprints

In the office.

The computer hummed loudly, and the desktop was a mess.

Wang Zhong aggressively searched for cases, but his actual efficiency was not high.

Primarily because cases were not categorized by footprints.

As a form of evidence, footprints were relatively useful. Imagine in a case, a footprint matched the pattern and wear on the suspect's shoe—it could corroborate that the suspect had been at the crime scene.

However, footprints as clues were sufficient for active cases but somewhat inadequate for cold cases.

Unlike DNA and fingerprints which have corresponding databases, footprints do not have a database.

At this stage, the police database only contained footprints collected from the crime scenes, basically only usable on a case-by-case basis.

Jiang Yuan watched Wang Zhong's operation and soon lost his patience, saying, "How about this? Just extract the images of the footprints; I think I saw that was possible earlier?"
