"Uncle Xun, what did you find?"

Four footprints were found in the green grove of the Triangle Garden in the downtown area, on the wet and sparse grass next to the victim's body. Two of them are clearly slightly larger and clearly in a group, and the other two are blurry but slightly smaller in a group.

He had been at the scene for forty minutes, and Xun Jianguo had been studying these two sets of footprints. Hearing Fu Yuan's question, Xun Jianguo still didn't look up, stared at the two sets of footprints in front of him, sorted out his thoughts a little and said, "These two sets of footprints, large and small, should have been left by the suspect." ”

"Old comrade, even I can see the huge difference in the size of these two sets of footprints. The big one should be 43 yards, the small one is up to 40 yards, how can it be left by one person?"

"You see," Xun Jianguo said, pointing to a clear and large set of footprints, "the toes and heels of this group of footprints only leave a vague outline, but the middle is clear enough to see the texture of the sole." This indicates that the shoes are too large and the suspect deliberately stepped on the middle of the shoes in order to leave a clear footprint. ”

"And how do you explain this set of vague footprints?"

"This set of footprints is even more distinctive. The reason for the blurring is not because the soil under his feet is hard, but because the suspect deliberately caused it. Xun Jianguo stretched out his hand to clean up the weeds around the footprints that had not been moved, and continued: "The forefoot is deep in the soil, indicating that the suspect was on his heels at that time. It's just that because the shoe is one size smaller, the heel still faintly touches the ground. ”

Hearing Xun Jianguo say this, Fu Yuan leaned down, and by the afterglow of the setting sun, he really saw a little slight trace on the sparse grass.

"The most important point is that the suspect walked in backwards wearing shoes one size smaller. ”

"Old comrade, how do you see this?"

"You take two steps backwards. ”

Hearing this, Jia Wei really chose a softer land and took two steps backwards. When I looked down, I saw that the footprints I had left were somewhat similar to those two blurred footprints.

"Because the shoes you were wearing were the right size, and you didn't carry the victim's body of more than 90 pounds, the toes didn't sink deep into the soil. You know, if you don't have special training, when you walk backwards, you will habitually push your toes the ground, and your heels rarely hit the ground. ”

"Uncle Xun, it stands to reason that the suspect should wear a bigger shoe when he comes in in order not to expose himself, and he is walking, why did he do the opposite?"

"That's where the cunning of the suspects comes in. The art of war is virtual, and the truth is virtual, and this is the most easy to be fooled between the virtual and the real. ”

"Did the old comrade say that the suspect was still a literate person? Moreover, he used the strategy used by Zhuge Liang in the chapter "Romance of the Three Kingdoms", when Cao Cao defeated Huarong Dao?"

"Indeed, the suspect's intentions are very obvious. ”

"Uncle Xun, can you see the height and weight of the suspect?"

"Now it can be determined that the suspect should be wearing size 42 shoes, and according to common sense, he should be about 1.75 meters tall. It's just that," Xun Jianguo hesitated for a while, and then said with uncertainty: "Due to the suspect's deliberate disguise, it is difficult for us to judge whether his real height and weight have deviated from the normal value." ”

Hearing Xun Jianguo, who has always been known as a "trace expert" and a baby bump in the city bureau, say this, Fu Yuan's head suddenly became a little bigger.

"It seems to be another very difficult murder case. ”

The reason why Fu Yuan said this was because the place where the body was dumped was obviously carefully chosen by the suspect. This is not only a blind spot for surveillance, but also a clump of green trees more than one person tall blocks the view of passing vehicles. In other words, it is impossible for a dashcam in any passing vehicle to capture the suspect carrying the body in.

"Don't be pessimistic, if people don't know unless they do it, no matter how cunning the suspect is, he will leave clues. ”

This is a verbal phrase that Xun Jianguo often said when he solved the case.

"If, I mean, old comrade. ”

"If you have something to say, just say it. ”

Don't look at Jia Wei, who usually likes to joke, but at work he is a person who loves to use his brain, and he is good at thinking about problems from different angles. Otherwise, he would not have been transferred to the serious crime team at a young age. So after hearing his words, Fu Yuan and Xun Jianguo turned their heads to look at him at the same time.

"If the suspect was underweight and wore a large number of soft-soled casual shoes when he came in, and a smaller pair of hard-soled shoes when he went out, would he have been able to leave such two completely different sets of footprints?"

After listening to Jia Wei's words, Xun Jianguo squinted his eyes and thought about it, then squatted down and looked at it carefully for a while, and suddenly patted his knee and said loudly: "Good boy, you have grown." ”

"Uncle Xun?"

"What Xiao Jia said makes sense. However, it is not that the suspect is underweight, but that he is heavy. In addition, I didn't come in in soft-soled shoes and go out in hard-soled shoes, but I came in in hard-soled shoes and walked backwards on my tiptoes in soft-soled shoes. ”

Speaking of this, Xun Jianguo suddenly shook his head and said, "It seems that there is something wrong." ”

Then he bent down and looked down carefully for a while before he said with great certainty: "It's not wrong, it must be like this." The suspect chose a pair of larger-sized hard-soled shoes in order to spread out the weight of the two people who came in, so as to confuse us. ”

"Why?"

"Look here. Xun Jianguo pointed to the footprints of the smaller one, stretched out his right hand with four fingers together, stretched out to the footprints stuck in the dirt and gestured: "Only when the sole of the shoe is very soft, standing on tiptoe and walking backwards, will leave footprints with a slight arc." ”

Fu Yuan and Jia Wei looked down at the same time to take a closer look, and sure enough, as Xun Jianguo said, the footprints left in the soil really had a certain arc.

In this way, it is not difficult to judge the height and weight of the suspect. It should be a standard height of about 175 cm, but the weight is on the heavy side, judging by the footprints of the larger size, it will not be less than 90 kg. ”

For homicide cases where there is no information on the source of the body, no surveillance images, and no discovery of the first crime scene, it is obviously far from enough to know the height and weight of the suspect. Still, something is better than nothing.

The investigation of most cases has to go through a gradual process from having no evidence, to obtaining sporadic evidence, to mastering key evidence, and finally solving the case. Therefore, Fu Yuan and the others were not disappointed.

Because they had to wait for the autopsy report, their current work could only be focused on finding the source of the corpse and the first crime scene.

Jia Wei looked up at Caixia in the western sky, then looked down at his watch, and asked tentatively, "Team Fu, do you still eat bean curd for supper tonight?"

"Whatever you want. As he spoke, he turned his head to Xun Jianguo and said, "Uncle Xun, let's go." ”

"Thank you, chief!" As soon as he heard this, Jia Wei gave a standard military salute to Fu Yuan and Xun Jianguo very exaggeratedly, then took out his mobile phone and quickly dialed his girlfriend's number, and said in a low voice and excitedly: "Xiaoli, I will invite you to a big dinner and watch a movie tonight......." ”
