Criminal Investigation: Collapse

At this time, Pei Shishi, who was still basking in the sun on the experimental field, was crying and mournful. He didn't know how many times he had cut the person who did these things to pieces. When a criminal policeman handed over a bottle of water At that time, Pei Shisi didn't say a word, and sat on the tree stump beside him, drinking water, while looking around with his eyes, but suddenly passed by a pit next to the pit, which was used by the technical team as a warning. Coiled traces of depressions.

According to the staff of the trace inspection department, this trace should be scratched by a rope. Pei Shishi frowned, and threw the finished mineral water bottle in his hand into their garbage bag, but he didn't want to be caught because of his habit. The action of sex shooting a basketball made him throw the mineral water bottle far away.

Just when Pei Shishi was about to pick up the mineral water bottle, he suddenly remembered the influence of habit on a person, just like Wen Lixi would always maintain a correct sitting posture, like some thieves would have a Like using a lock-picking technique to open all the locks in the world, Pei Shishi turned to look at the only trace left on the scene.

Immediately, he took a few steps closer to the mark and squatted down to take a closer look. He took the measuring ruler and measured the width of the mark again. The diameter of the mark was about 22mm. In the autopsy report, I saw the analysis of the strangle marks on the body of the deceased. The rope used to bind the deceased was also a hemp rope with a diameter of about 22mm.

Experienced criminal investigators will know one conclusion, that is, many criminal suspects have specific criminal methods, and when they choose the tools to commit crimes, they will choose the things they usually use habitually. The rare 22mm rope appeared many times in this case, which is very likely to indicate that the murderer was very likely to be a person who was extremely good at using this kind of rope in his previous life.

"Xiao Qi!" Pei Shishi called to the side, and when he was about to stand up to speak, he had to support the trace inspector called Xiao Qi because of low blood sugar.

After a few minutes, Pei Shishi asked slowly, "Where are these 22mm ropes used now?"

Xiao Qi thought about it in his mind, and replied: "This kind of rope is thicker than the commonly used ones, expensive and heavy. Many years ago, no one used it on the market, and it was directly canceled by major manufacturers. Because bioengineering sometimes needs to bind the soil quality of some special plants in their experimental fields, so this kind of rope has become a special item in their biological field."

As he said that, Xiao Qi saw Pei Shishi staring at the traces beside the pit, and asked, "What's wrong?"

Pei Shishi hissed, rubbed his chin and said, "This mark doesn't look like a bondage mark, but rather... like a drag mark."

Xiao Qi nodded, "This is indeed a drag mark, and based on the depth of this and the degree of friction around it, we speculate that the heavy object dragged by the rope at that time was about [-] kilograms."

"Fifty kilograms?" Pei Shishi stretched out his hand to block the sun above his head, muttered, and then said, "Aren't there any other drag marks of related objects?"

Xiao Qi shook his head, "Speaking of it, it's very strange. There are rope marks but no other traces. I haven't thought of other possibilities except that someone has dealt with the scene, but since I have dealt with it, why don't I also take this trace Get rid of it?" There was a little doubt in his tone.

Pei Shishi didn't care if his hands were not clean, so he wiped his face, and nonchalantly slipped out a few trash words from his mouth, "Maybe this grandson is blind and didn't see it? Who knows?" Well, anyway, you can’t use human thinking to think about these things, how can a human do such a thing?”

"..." Xiao Qi didn't speak, mainly because Xiao Qi didn't know how to answer such nonsense.

Seeing the expression on Xiao Qi's face, Pei Shishi patted Xiao Qi's shoulder, "Don't make such an expression, there was a case before, and the murderer used a thinking pattern that he didn't know where he came from, anyway It’s not something people can think of.”

Xiao Qi nodded expressionlessly, indicating that he remembered it.

While Pei Shishi was talking, he took out his mobile phone from his trouser pocket and called Jiang Yin, intending to tell Jiang Yin what he just discovered. "Hello? Brother!"

When Jiang Yin received the call from Pei Shishi, he happened to read all of Tian Wendong's interrogation records.

"what happened?"

Pei Shisi told Jiang Yin what he had just discovered bit by bit. The mobile phone was placed on the speakerphone, and the other two people in the office could also hear what Pei Shisi said. When she found out that the rope was a tool specially provided by Bioengineering, Liu Sichan turned her eyes from the stack of documents in her hand to the mobile phone in front of Jiang Yin.

Jiang Yin obviously also remembered the special rope marks that appeared in the autopsy report at that time, and when Pei Shishi said it, he nodded slightly.

"You can come back when you're almost ready." After Pei Shishi finished speaking, Jiang Yin picked up the interrogation record in front of him and put it on the table.

As soon as he hung up the phone with Pei Shishi, a criminal policeman knocked on the door of Jiang Yin's office with a blue wallet.

"Team Jiang, take a look, these are the reports we compiled just now."

The criminal policeman handed the clip in his hand to Jiang Yin and said: "We checked all the convoys that transported the plant seedlings, and found nothing suspicious, even the vehicle registration form for this month's entry and exit. Yes, no problem at all."

Jiang Yin flipped through the report, and heard Liu Sichan say: "Then what if these are all fake?"

Jiang Yin's mobile phone paused, then raised his head and asked the criminal policeman, "Has the technical team finished the surveillance investigation?"

The criminal policeman shook his head and said: "It's only less than half of the investigation. Since I got it back yesterday afternoon, the technical team has been looking at it in rotation. The main reason is that I don't dare to fast forward at all. I have to look back bit by bit. .”

"Then ask the brothers who stayed in the Bureau of the Trace Section to help to watch, and also focus on checking the monitoring on the day of the car accident and the monitoring from all angles on the day when the last transport convoy entered the training center." Jiang Yin faced The criminal policeman said: "Also, let the Ziren District and Beishan District Bureaus not be idle. Since the case happened in their jurisdiction, let them check all the surveillance cameras along the road on the day of the car accident, and look at the people sitting in the car. The person, the route, where did he come from." The criminal policeman nodded and went out to work again.

Suddenly, Liu Sichan closed the document in front of her, looked at Wen Lixi and asked, "Tian Wendong said that he has never seen the person behind the scenes, how credible is it?"

Wen Lixi thought about it, "I don't think there is any possibility of him lying."

After receiving the answer, Liu Sichan didn't ask why. After a moment of silence, she opened her lips and analyzed slowly: "Tian Wendong has never seen the face of the person behind the scenes. She looks like she doesn't know much about this matter, and for the time being, I also believe that she doesn't know the face of the person behind the scenes, why can't a person show her face when she shows up?"

It seems that it has been a long time since Liu Sichan said such a long sentence. Halfway through the sentence, Liu Sichan obviously had to pause because of the problem of sentence punctuation before continuing, "The essence of the sum of thousands of reasons is that this person does not want to reveal his identity. Why doesn't he want to reveal his identity? Apart from not wanting to be arrested and other obvious subjective reasons from our point of view, there is also a reason from their point of view that he is a well-known person by people like Gu Xin and Tian Wendong. people."

Jiang Yin was taken aback when he heard the words. Indeed, he felt that this person was a very mysterious person from the very beginning. In addition, Gu Xin had been in contact with this person on the phone all the time, so he preconceived that this person was someone far away from these people. hand, but in fact, the phone or not, does not have any contradiction with whether this person exists beside Gu Xin.

Jiang Yin nodded, and thought about it: "Just like we summarize the serial cases, why are these people related to the case? Maybe... this person is the intersection of these people who had no relationship at all."
