Chapter 635 - 579
Criminal detectives all have their little tricks.
Without needing further instruction from Jiang Yuan, Wang Chuanxing took advantage of the arrest to photograph the footprints of the two Jin Family daughters, the three daughters-in-law who arrived later, and even those of a more distantly related aunt.
Jiang Yuan just stood in the yard and watched, focusing on the gait. When he came across rather common footprints, he would take a closer look.
The gait of an individual is actually quite distinctive. For example, in families with children, when the child follows an adult and learns to walk, almost every child will imitate the adult’s way of walking perfectly.
This is a special ability that children have to grasp details.
Footprints are much the same. To the average person, identifying footprints is akin to distinguishing between the faces of dogs, cats, or pigs—if there are significant differences, they stand out; otherwise, they seem vague and uncertain.
But for experts with special training in footprints, reading them is as natural as recognizing faces. There is no need for overly special descriptions. With experience, the differences become naturally apparent, and sometimes they can’t even be objectively described. This is one reason why computer systems struggle with facial recognition.
In the end, at least for now, the human brain’s processing capability is still more advanced than that of computer systems.
Jiang Yuan’s footprint identification has now reached level LV5. He didn’t even need to activate temporary skills to memorize the footprints of the Jin Family’s female members within minutes. Of course, this was only a temporary memory, but it was like sitting on the couch in a SK bar and calling out, "Next batch," and then recognizing anyone who reappeared.
Jiang Yuan, with his hands behind his back, went back to the meeting room, brewed a cup of tea, and took a couple of sips before saying to Mu Zhiyang, "Call home and ask for reinforcements from the Cold Case Squad for the next few days."
