Detective: I can see the criminal record

To confirm the origin of the footprints that appeared at the scene, the best way is to conduct footprint identification.

This is a technique that I have learned in the police academy for a whole semester, but is rarely used in the process of handling cases. Even top academics like Cen Lian and Wu Qiushan have little accomplishments in footprint identification.

It's not because they don't work hard, but because there are fewer and fewer applications of footprints, and there are very few cases for them to practice on. Even the cases mentioned in school were many years ago.

In the process of handling cases, what they most commonly use is mainly the comparison of footprints and shoe prints, and rarely involves the analysis of footprint outlines and indentations. Firstly, because the cement floors that can be seen everywhere now make the clarity of footprints serious. The reduction is also due to the development of the Sky Eye system, which has transferred the work of tracking criminal suspects from following footprints to following surveillance videos.

Of course, just because it's not commonly used doesn't mean it won't be used. Cen Lian called and pulled Wu Qiushan out of the laboratory, along with the fixed footprints.

"You suspect that this footprint may not necessarily be that of a male," Wu Qiushan immediately expressed his agreement after hearing their thoughts. "I also feel that something is wrong now. We have been assuming that someone guided Wu Yuelei to kill her husband and cheat her bail, but This assumption is too difficult to establish.”

As he spoke, he took out the shoe print he had extracted from the soil on the mountain.

Because this footprint was extracted from the soil, the edges were very clear. Cen Lian tried hard to recall what he had learned in school and began to analyze the footprints in detail.

After about ten minutes, he finally said with certainty, "It's big shoes on small feet."

Wu Qiushan's eyes lingered on the footprints for a while, and after repeated verification, he nodded, "Yes, the shape of the outline of the footprints is wrong, and the stress points on the feet are wrong, especially the heel. The shoe print is too shallow. , indicating that the person who left the shoe print subconsciously leaned forward to maintain balance while standing on the unstable soil, which caused the heel part that was much larger than her actual foot length to be slightly raised. "

The two of them had not analyzed such a footprint in detail before, and when they examined it carefully now, they discovered the details that they had overlooked before.

"The width of the foot is also a bit off, and there is also a problem with the arch." Cen Lian stared at it for a long time and finally confirmed, "High arches are more common in women, so this footprint is indeed more likely to be that of a woman."

Although the camera did not capture any signs of women going up and down the mountain in the past few days, Wu Yuelei had not been controlled by the police the day before they went into the mountain to investigate, which means that it was entirely possible that she went up the mountain that day.

"She was deliberately inducing us," Wang Yuanteng sighed, "It's also our fault for being preconceived and ignoring that she was the biggest beneficiary after Zhang Changbin's death."

"What about the two deceased people?" Lin Xiangqi interrupted them, "Wu Yuelei killed Zhang Changbin to kill her husband and get bail, so what happened to these two deceased people."

Now, Cen Lian looked at the two corpses and once again had no clue.

Because the criminal record on Wu Yuelei's head is indeed only for killing Zhang Changbin, then who used the same method to kill these two victims? Or, where did Wu Yuelei learn this killing technique?
