Mystery Tracker 2

The direction was initially established, and further investigation of the case began immediately.The next day, several people went to investigate separately according to the direction of the division of labor.However, what they didn't expect was that the breakthrough came faster than they expected. Chang Luqing brought Xu Leyou to the office of the serious crime team at around ten o'clock in the morning.

"Captain Shen, I brought someone here today to admit my mistakes to you." Chang Luqing said with a serious face, "I went back yesterday and had a good chat with Old Xu. He has something to tell you now."

After finishing speaking, Chang Luqing dragged Xu Leyou to Shen Yan.

Compared with yesterday, Xu Leyou at this moment is obviously a little bit guilty.He looked at Shen Yan, then at Chang Luqing who was beside him with a dark face, and then he said tremblingly: "Captain Shen, I'm sorry, what happened yesterday... I, I lied..."

Although Shen Yan had long guessed that Xu Leyou might have a problem, he didn't say much at the moment, but asked, "What did you lie about?"

"Yesterday, I said that I have been in the factory for the past few nights...Actually, I haven't... Among me, I have been out..."

"Go out?" Shen Yan winked at Cheng Haiyang who was next to him, and the latter understood, and immediately took a notebook and started recording.Shen Yan turned around and asked, "When did you go out? What did you do?"

"I... I went out after 11:[-] midnight the day before yesterday... to go out..." Xu Leyou took a peek at Chang Luqing when he said this, and then he swallowed, and then said with difficulty: "I'm going out to sell Parts gone..."

Hearing what Xu Leyou said, Shen Yan immediately understood.Although the whole car has been eliminated after entering the recycling plant, many parts are still useful, so some car repair shops will buy parts from them.There are two main reasons for this. One is for the maintenance of those vehicles that are still in use. This kind of vehicle is often too old and the original factory has ceased production, so we can only find the same parts from old vehicles. The second is that this repair shop is too unscrupulous, using things from old cars to reduce costs and shoddy them.But no matter what the reason is, auto parts are one of the important sources of income for this kind of recycling plant. Xu Leyou's approach is definitely stealing from the inside out.No wonder he was so afraid of Chang Luqing.Thinking of this, Shen Yan already understood how Chang Luqing found out that Xu Leyou was lying. For this kind of thing, as long as you check the parts of the processing plant, you can easily find the problem.

"Have you been out these few days? What time and what time are they?"

"I... I don't go out many times..." Probably feeling Chang Luqing's low pressure, Xu Leyou's voice became softer as he spoke.Shen Yan also noticed this detail, so he said to Cheng Haiyang in a blink of an eye, "Hang Yang, take Xu Leyou to the next door to make a detailed record."

Cheng Haiyang understood, nodded, and said to Xu Leyou, "Follow me."

Xu Leyou looked up at Chang Luqing, seeing that the latter had no objection, so he left with Cheng Haiyang.

Seeing the two people walking out of the office, Shen Yan turned back and said to Chang Luqing: "Manager Chang, thank you for cooperating with our police work, but before the case is investigated clearly, we need to keep some things secret, so I hope you don't mind."

"Okay, Captain Shen, I understand." Chang Luqing nodded, and then complained to himself: "I'm just angry with Lao Xu. This person has been with me for several years, what kind of person am I? He should know! I can bear him selling things from the factory for money, but now that people are dying, he still refuses to tell the truth for the sake of face! If my secretary hadn't found out the real evidence of him stealing and selling things, he wouldn't know How long are you going to be so hard on me! How come you say this person can't even tell the priorities?!..."

For Chang Luqing's complaints, Shen Yan didn't respond much, he just asked: "Manager Chang, how many people can get the door key of your recycling plant?"

"Except for the one in my hand, the other two are kept in the concierge. One is carried by the person on duty, and the other is kept in the drawer of the concierge. Liu Mingquan is on duty in the concierge during the day, and Mr. Liu is on the night shift. Xu. However, the concierge’s room is usually not strictly controlled, and the workers can go in, so it’s not impossible for someone to secretly allocate one.”

"What about the one in your hand?"

"My phone is usually kept in the drawer of my office in the city, and it is basically out of reach of others."

Shen Yan nodded.

After more than 20 minutes, Cheng Haiyang finally walked back from the next door with Xu Leyou.Cheng Haiyang handed the notebook to Shen Yan. Shen Yan looked at it and nodded slightly.

"Xu Leyou," he raised his head and said to Xu Leyou, "We may have to ask you to find out about the situation recently, so you'd better not leave the city for the time being. Also, if you think of anything in the past two days, you can also contact us."

Xu Leyou nodded a little sluggishly, then looked up at Chang Luqing.

Chang Luqing scolded with a straight face: "Do you remember what Captain Shen said?!"

"I remember it clearly!" Xu Leyou hurriedly replied, "Clearly..."

Chang Luqing looked at this person, sighed helplessly, and then said to Shen Yan: "Then Captain Shen, I'll go first, if there is anything that needs our cooperation, just come to me."

"it is good."

Chang Luqing took Xu Leyou away, and Shen Yan picked up the interrogation transcript again.

"According to Xu Leyou, he has been secretly selling parts for a while." Cheng Haiyang said. "Xu Leyou knows someone who runs a repair shop. From time to time, he will ask him to help get some parts. When Xu Leyou sees a suitable car or parts when he is on duty at night, he will unload it by himself or ask that person to come and pick it up. The day before yesterday—that is, the night of the 19th, he picked up a few more parts, and then went out to sell things to earn money. According to himself, he went out around 11:[-] in the middle of the night and came back around [-]:[-] in the morning. When I came back, I saw that the gate of the factory was locked, so I thought no one had gone in." After Cheng Haiyang finished his narration, he gave his own inference, "I think that the car probably came in while he was out. of."

"Why?" Shen Yan asked.

"Xu Leyou said it himself." Cheng Haiyang replied, "This guy was afraid that his boss would find out about the good things he did, so he insisted that he didn't know anything. Now that the matter has been exposed, he probably wanted to be lenient. On the contrary, it is a special cooperation. According to his account, he usually takes a good look at the new car that comes in during the day, because there are things that he can use inside, but he has no impression of this car, so it should not be the previous car. Just went in. And I asked him, he said that he didn’t check the car before and after he went out the night before, so he himself said that the car probably came in during the time he was out.”

"If this is the case, it means that the murderer is a person who knows the situation of the factory very well—or someone who knows Xu Leyou very well," Shen Yan followed Cheng Haiyang's train of thought to analyze, "Xu Leyou didn't go out for a long time, there was only one more than one person before and after." Hours, the suspect was able to get the car in during this time, which shows that he is very aware of Xu Leyou's actions at night, and has prepared the keys in advance. Haiyang, you go to the depot again and tell Jiang Li our findings, and then you two Then ask those workers carefully to see if anyone knows about Xu Leyou reselling the parts, and who else has the opportunity or has been assigned the key of the gate."

"Yes!"

As soon as Cheng Haiyang left, Shen Yan was the only one left in the office.There are too many clues in this case, and several people from the serious crime team are running around outside today.Shen Yan looked at the time and felt that Jiang Ruiheng's autopsy should have the results, so he decided to go upstairs to have a look.

When Shen Yan came to the sixth floor, unexpectedly, Jiang Ruiheng was not here. He heard from his assistant that he had gone to the seventh floor.So Shen Yan went up to the seventh floor, and after asking Cheng Jinsong, he found out that Jiang Ruiheng was actually in Shen Hao's office.

"Hey, are you here?" Seeing Shen Yan walking in with Cheng Jinsong, Jiang Ruiheng looked up and said hello, "Are you looking for your brother or me?"

"Looking for you, I want to ask if you have finished the autopsy." Shen Yan said as he walked over, seeing the two people staring at the computer screen, he asked, "What are you looking at?"

"Make a simulation." Jiang Ruiheng said, eyes still on the computer screen.

Shen Yan looked at the monitor, and saw that on the left side of the monitor was a three-dimensional virtual map of the trunk of a car. This picture was from a top-down perspective. Through the virtual car cover, one could see a person curled up inside. Dead bodies thrown in the trunk of a car.On the right side of the screen, there are a lot of letters and numbers, and there are several graphs that Shen Yan can't understand.

"What is this?" Shen Yan couldn't help asking.

"A software that simulates the situation after a dead body." Shen Hao explained. "It sets up some common environments for dumping corpses. As long as we input relevant data, the software can simulate and calculate the corruption of the corpse, or calculate the time of death based on the condition of the corpse. Brother Rui Heng said that the dumping of the corpse this time The situation is more complicated, and I want to simulate it through software as a reference."

"There is this kind of software?" Shen Yan looked at Cheng Jinsong in surprise, "Is this also the new one you bought?"

"Well, it was developed in the United States. Several universities in the United States have specialized corpse farms to study the process of changing corpses under various conditions. This software is made based on their research results."

As soon as Cheng Jinsong finished speaking, Jiang Ruiheng continued to explain: "This time, the corpse was thrown in the car, and the temperature change in the car will have a great impact on the change of the corpse, so I asked Shen Hao to use software to simulate the abandonment of the deceased." Dead environment, minimize the error."

"Then is the result out now?"

"Waiting for the final result."

As soon as Jiang Ruiheng finished speaking, he saw that the curves on the right side of the screen were all refreshed once.Apparently it worked out.When Jiang Ruiheng saw it, he and Shen Hao pointed to the screen to study it. Cheng Jinsong also joined their discussion, and Shen Yan waited quietly. After a while, the three of them nodded, as if they had a result.

Jiang Ruiheng raised his wrist and looked at his watch, and then said to Shen Yan: "The time of death of the male deceased should be between 6 am and 10 am the day before yesterday, and the time of death of the female deceased should be between 11 am and 2 pm the day before yesterday. The same sentence, the main thing is not sure how long the two people stayed in the car, what is the temperature in the car. Shen Hao and I took two extreme values ​​based on the weather forecast for the past two days, and came up with the current This result."

"Is it possible that the two died at the same time?"

"Probably not." Jiang Ruiheng shook his head. "The current result is a conclusion based on the combination of autopsy and computer simulation. It should be accurate, unless there are other factors that can affect the decay of the corpse."

Jiang Ruiheng said, looking at Cheng Jinsong questioningly.Cheng Jinsong shook his head: "We haven't found anything special so far."

Hearing what the two said, Shen Yan nodded reassuringly, and then asked: "Is the cause of death of the two determined?"

"It is confirmed that the male deceased died of mechanical injuries. The deceased's skull had multiple fractures, mainly concentrated in the right occipital bone and right skull, and one of them hit the brainstem of the deceased, causing acute brain damage. Bleeding should be the main cause of death. The female deceased died of pyrogenic dehydration caused by high temperature, and the murderer made secondary injuries to her body after her death, mainly focusing on the deceased's breasts and genitals. .”

"That is to say, the murderer killed the male deceased first, and then locked the female deceased in the car, but unexpectedly, the temperature in the car was too high, causing the female deceased to die of lack of water. After the murderer found out, he then locked the female deceased The dead body vented..." Shen Yanshun analyzed downwards, frowning slightly, "So, the murderer hated the most, should be the female dead Sun Yulian?..."

"Brother, didn't you say that Sun Yulian was a prostitute?" Shen Hao asked, "Could it be that the murderer found out that Sun Yulian was prostitution to the dead man, so he became angry and beat the dead man to death first, and then took him away Sun Yulian, and found out that she accidentally killed her, so she vented on her corpse?"

Shen Hao's conjecture was reasonable, Cheng Jinsong and Jiang Ruiheng did not raise any rebuttals after hearing it, but Shen Yan frowned, as if they still had some doubts.

And at this moment, Shen Yan's cell phone rang.Shen Yan took a look and picked up the phone.

"Hello, Qin Kai."

"Boss, are you still in the bureau?"

"Well, yes."

"Okay, I'll take someone back right away." Qin Kai's voice sounded rather eager, "There are important discoveries!!"
