Criminal Investigation Files

Lu Siyu explained as he walked out: "This person's foot has a slight slope, although it doesn't affect walking, but it is obvious that when standing on the ground, one foot is relatively stable, and the other foot is extended. If it was him, the footprints left should be in the shape of a figure of eight, and should not be buckled inward."

"Also, the soil on his feet is different, there is yellow pollen on his body, and there is a faint fragrance. If I smell it correctly, he has been contaminated with a flower called scorpion grass. This flower, as the name suggests, It only blooms after [-] o'clock in the evening, and it will die before morning, and his trousers and soles are stained with this kind of pollen, so he must have stayed in a place with a large area of ​​this kind of flower."

"After it rained last night, the rainwater on the bottom of the trousers and the soles of the shoes happened to mix with the pollen. We walked around this small village. This kind of flower only appeared on the hillside outside the resort in the village."

"Today we passed by the flower field. I saw many mineral water bottles, cigarette butts, and some mixed footprints. In the dead of night, so many people are hiding in the wild. It's probably because they are spreading wild paste. Wang Yu dare not go into details , probably because they were afraid that Officer Zhang would detain their group."

Putting wild paste is a name for secret gambling in the countryside. Usually, the location is the wilderness, the quick solution, and the amount is relatively large.

Now these villagers are also afraid of being investigated, and they will not carry large amounts of cash. Everyone trades online, so when he said that he wanted to check Wang Yu's mobile phone, Wang Yu became nervous.

These reasonings seem mysterious, but they are actually based on some tiny details. Song Wen straightened it out, and couldn't help feeling: "Your nose is really good. I just think that man smells a little bit, and I can't smell it at all."

Lu Siyu continued: "Also, what he said also makes sense. If an electrician kills people by receiving electricity, it's too obvious. This strong man is seeking money. Zhou Chuguo was the one who was beaten. The matter has not yet come down, so there is no reason to kill the whole family at this time. The most important point, I think if he connected the wires last night and killed the family with electricity, he would not have slept until after nine o'clock in the morning. He paused for a while, panted and said, "After checking this, I want to understand one thing."

"What's the matter?" Song Wen followed behind Lu Siyu, "Oh, you walk slowly. Where are we going?"

Just now Lu Siyu got up suddenly and motioned him to go outside, but didn't tell him where he was going.Lu Siyu turned around and answered him with four words: "Look for evidence."

After Lu Siyu finished speaking, he kept walking forward. He walked very fast, as if he was anxious to go somewhere, and Song Wen followed behind, unable to keep up with him.He thought that Lu Siyu wanted to go to the scene to have a look again, so he didn't ask any more questions.

After walking like this for a few minutes, they had already reached the vicinity of the courtyard where the crime occurred, but Lu Siyu didn't go in that direction, but took another road, walking up the not too high hillside that he saw before.The hill is lush and lush, with a lot of vegetation, and the scenery is pretty good.

Song Wen didn't have any leisure time, he was even more confused: "I still don't have a clue about the case, what kind of mountain did you climb?" After asking this sentence, before Lu Siyu could answer, he followed closely, "You Don't wait for news from Zhang Dahai?"

Lu Siyu was slightly out of breath: "Zhang Dahai is unreliable. I want to go back as soon as I get news of him. Besides, Wang Yu is right, what we lack is direct evidence. Otherwise, it is considered a It is also difficult to convict a real suspect."

In handling a case now, what matters is the integrity of the evidence chain. The reason why this case is stuck here is because there is too little direct evidence. There are no witnesses, no evidence, no fingerprints, and only half a vague footprint. This situation is very passive. , Even if the suspect is found, as long as the other party bites to death and says that he did not do it, they will not be able to break through.

The more he walked up the mountain, the steeper the road became. Lu Siyu climbed for a while without saying a word, and he replied to Song Wen's words when he was almost on the top of the mountain: "I'm just guessing, not necessarily accurate. I was trying to figure out the psychology of the murderer. This murderer didn’t kill with passion, but planned to kill. Suppose you wanted to kill someone and made a plan that you thought was perfect, would you lie down and sleep at home and wait for that plan to be implemented?”

Song Wen thought for a while and shook his head: "No! I'll probably just pack up and prepare to run away..."

Lu Siyu raised his forehead: "A person like you really can't kill people." He explained, "This murderer wants to kill them all. There must be a deep hatred between them. The murderer will have fear, will There is anxiety, but it should be more anticipation! Excitement! He must witness the last moment with his own eyes and watch those people die, so that he can relieve the hatred in his heart and bring him the greatest pleasure."

It's like the finale of a play, when fireworks are set off to ignite the fire letter, and when it's time for the exam to reveal the rankings, without this final step, all previous efforts would be useless.

Song Wen suddenly realized, "So we are going to..."

Lu Siyu took three steps and made two steps, and went up to a platform on the top of the mountain.This mountain bag is not too big, probably tens of meters higher than the one below.With such a high distance, I can already feel the difference between the wind on the mountain and the wind down the mountain.Lu Siyu's chest heaved and heaved his eyes, and immediately selected an open space, then he walked to the side and leaned down.

Song Wen followed Lu Siyu to look down from here, and he could see the small courtyard of Zhou Chu State in full view, and he could clearly see any movement in the courtyard, Lu Siyu said softly: "Yes, it's here, the best Observation point."

This platform may have been walked by a lot of people, there is no vegetation, it is just some dirt land, Song Wen looked down, and sure enough, as Lu Siyu said, he found a few clear footprints on the ground not far away. It was exactly the same as the one that was accidentally destroyed by Zhang Dahai at the gate of Zhou Chu State, and there were some brown-red soil blocks under the footprints, which were also the same color as the ground at the gate of Zhou Chu State.

Lu Siyu took a few photos with his mobile phone.

Song Wen squatted down, took out the evidence bag that he carried with him, carefully picked out a cigarette butt from the grass and observed: "It rained yesterday, but this cigarette butt is dry, it is very likely that the murderer left it in the morning. "Beside the soot, there was another group of tight footprints on the ground.

When the murderer was at the gate of Zhou's house, he was still vigilant and didn't leave too many traces, but when he got here, he completely relaxed and left a lot of evidence.

The DNA of the murderer can be detected from the cigarette butt, and they have obtained the complete and clear footprints of the murderer. With these evidences, the murderer will be crucified.

Lu Siyu stood up and looked down: "After he connected the wire last night, he didn't sleep much all night. He climbed to the mountain before dawn, stood here, and watched those people die. This cruel murder The method is probably a 'masterpiece' in his mind."

From the cigarette butts and shoe prints, it can be seen that the killer once waited anxiously here.This morning, when the sky was getting dark, he was here, smoking a cigarette, walking back and forth, waiting for the tragedy that excited him to happen.

Song Wen turned to look at Lu Siyu. If he was an ordinary person, he would not have thought that the murderer was standing on a hill not far away watching all this when the crime happened.Even if you want to expand the search area, at most you should search the vicinity more, and you won't come to the top of the nearby hills.

Lu Siyu's face was flushed because he had just finished exercising, but the corners of his eyes and brows were a little proud of his own thoughts. The wind blew his hair on his forehead, revealing his snow-white forehead.When analyzing the case, Lu Siyu looked no longer as cold as usual. He was very bright, but it also made Song Wen feel a little strange. Lu Siyu's tone seemed to be that killing people is a terrible thing in this world. What makes people intoxicated is an art that no one can understand.And he was able to sympathize with the murderer and understand the feeling.

Song Wen stood beside Lu Siyu, blown by the cold wind, and had a momentary illusion. He felt that Lu Siyu was not like a criminal policeman, but more like a perverted killer who would kill the whole family, but he was so smart, so sharp, so nice.

Song Wen likes to solve crimes, and catching bad guys will give him a sense of accomplishment. At first, he just held his breath and wanted Song Cheng to respect him, but later, he found that he really enjoyed this process. Even in the dark, he wanted to Seek justice.

Lu Siyu is different, if every murder case is a game of chess, he is doing a review, and solving all these can give him great pleasure.

The same is to solve the case, one of them is righteous, and the other is evil. The purpose of the two is the same, but the starting point is completely different. If a balance can be maintained, they can complement each other very well.

But if this balance is broken...

Facing the mountain wind, standing on the top of this small slope, Song Wen wondered a little, if the person in front of him is a murderer, can he catch him?

After saying those words, Lu Siyu suddenly felt a dull pain in his body. He was forced by this feeling to cough twice, squatted down, and pressed the sore spot. When he climbed the mountain just now, there was a slight pain in his stomach He didn't pay attention to the convulsions, but when he stopped now, he felt that a hand in his body crumpled the tender internal organs like a piece of waste paper.

Song Wen saw his face turn pale, then squatted down, and hurriedly asked him, "What's wrong?"

Lu Siyu calmed down, thinking that maybe he was greedy and ate a few extra pieces of spicy white meat at noon, which probably caused a stomach problem. He didn't want Song Wen to worry, so he said, "Maybe it's because I came here in a hurry, I'm out of breath..."

Song Wen asked anxiously, "What were you in such a hurry for? I kept telling you to slow down."

This time was very uncomfortable, cold sweat broke out on Lu Siyu's forehead, his slender fingers gripped the clothes tightly, and pressed against his stomach fiercely, wishing to penetrate into his body, he felt like there was a knife in his body It was twisting, it felt like the organs in the body were cramping, he gritted his teeth and said, "If you let me rest for a while, I'll be fine." His voice trembled, and it didn't sound like it at all. It looks like nothing is wrong.

Song Wen looked at Lu Siyu. In just a short time, the color of his lips changed, cold sweat broke out on his forehead, and his handsome face became paler. This posture made him a little flustered. Hold on, or I'll carry you down."

Lu Siyu closed his eyes and shook his head.

Song Wen was at the side, unable to help him, and wanted to help him up, but Lu Siyu's body was hunched up, his eyes were closed tightly, and his eyelashes were shaking violently. After a while, he said in a hoarse voice: "Don't touch me. . " There was even a crying sound in this sentence, which scared Song Wen so much that he didn't dare to touch him again.

Lu Siyu knew clearly in his heart that when he was waiting for Song Wen to go out in the afternoon, he secretly took painkillers, and it was time to take effect, and if he was lucky, he would pass it after a while.

Song Wen wanted to say something else, but Lu Siyu took a breath, turned his head and said, "Your phone is ringing..."
