Mystery Tracker 3

"What?!" When Cheng Jinsong said this, everyone's expressions changed.

Qin Kai glanced at the bag of human tissue, and said in shock: "Boss, Brother Jin, this, could it be that... the case of dismembering and boiling the body 20 years ago?"

Cheng Jinsong coughed slightly, glanced at the workers at the garbage dump not far from them, and indicated that there were outsiders present.Seeing this situation, Shen Yan whispered to Cheng Jinsong, "I'll go over and get them away first", and then walked towards the group of workers by himself.

"I want to know the situation when you found these things, please come with me." Shen Yan said, leading the group of workers aside.Seeing that the outsider was led away, several members of the serious crime team immediately moved to Cheng Jinsong's side.

"Twenty years ago, there was a vicious murder case in S city. The deceased was a college student, female. After she was murdered, her body was dismembered by the murderer into more than 20 pieces, boiled, and dumped in multiple places." Cheng Jinsong introduced , Every sentence made everyone look more serious, "One of the bags contained the internal organs of the deceased, and the intestines inside were neatly folded—just like the one we saw just now."

"So this case may be the same murderer as the previous case?" Jiang Li frowned.

"We can't be sure for now," Cheng Jinsong said, "but the case of that year has not been solved so far. That is to say, the murderer is probably still at large, and the possibility of committing another crime cannot be ruled out. So everyone must keep their spirits up." , take this case seriously."

"Yes!"

Over there, Shen Yan also walked back: "I asked the workers, they said that this batch of garbage was brought in this morning, and the workers found this bag of things when they were sorting. Because they reported it after they found it. The police, and then the police blocked the place, so they have not yet confirmed whether there are bodies in the rest of the garbage. In addition, the driver of the garbage truck is not here now, so it is not clear where the garbage was collected. And there is another problem," Shen Yan turned his head, looked at the endless landfill in front of him and said to Cheng Jinsong, "We can't be sure whether there are other parts of the body that have been buried in the ground."

"Even if the muscle tissue may be ignored and disposed of, the bone part cannot be ignored." Cheng Jinsong said, "I suggest you check with the garbage truck driver first where he collected the garbage this morning, and then pick up the garbage near there." Search carefully, maybe you will find something.”

Shen Yan nodded: "Director Guo has already contacted the driver of the garbage truck, and it is said that he will be there soon."

While talking, voices sounded from the cordon, and it turned out that the driver had arrived.This is a middle-aged man in his 40s.Shen Yan first revealed his identity to him, and then got straight to the point: "Master Huang, which garbage collection points have you been to this morning?"

"My car is mainly in charge of the university town in the south of the city. I have 14 garbage points along the way. Every time I go to a place, the people at the garbage point will help me dump the garbage into the car, and then I will be responsible for pulling it back." Huang The master obviously didn't know what happened, and asked with some doubts, "Comrade policeman, what happened?"

"Did you find anything unusual during the garbage collection process?"

"This...is the same as usual, nothing different..."

"In this way, you can recall your driving route this morning in detail, what time did you leave, where did you go first, and where did you go next, the more detailed the better." Shen Yan said to him.

Master Huang nodded, took out his phone, opened the map, and began to describe his driving route.Shen Yan and Cheng Jinsong listened carefully, and the more they listened, the more serious their expressions became - because the car passed through a large area, which undoubtedly added a lot of difficulty to the later search.

"The area is so large, we may not have enough manpower to search by ourselves, so we should ask the sub-bureau for help." Fang Liyuan discussed with Shen Yan in a low voice.

"I agree," Cheng Jinsong nodded, "Chengnan Branch can arrange personnel to go to the nearby area to investigate, and we will gather here to go through all the garbage brought in today. If this case is really related to the case 20 years ago , then there must be more than one bag of body parts.”

Shen Yan remembered the data recorded in the dossier, and his brows furrowed even tighter.He said to Fang Liyuan: "Li Yuan, you should go to the Chengnan branch and ask Bureau Zhao to help organize the manpower and conduct investigations with all the garbage spots as the center. If we find any clues that can narrow the scope of the investigation, we will notify you as soon as possible. "

"Okay." Fang Liyuan nodded and left quickly.

Returning to the crowd, Cheng Jinsong clapped his hands and said, "Everyone, everyone knows what's going on now. Judging from the current situation, there may be other body parts here, so all the garbage brought here today, We'll all go through it again."

Following Cheng Jinsong's words, everyone looked unconsciously at the hill-like garbage dump in front of them and the five or six garbage trucks parked behind it that hadn't been dumped yet.

"As you know, the Hongshan garbage dump is responsible for the domestic garbage of the entire S city, so the workload will be very heavy. In order to improve efficiency, we will ask the sorting workers of the garbage disposal yard to help us investigate together. Each of you and a Workers form a group, and once they find suspicious garbage, they will immediately notify us for confirmation. In addition, when rummaging through the garbage, pay attention to the physical position relationship between the garbage. The largest pile uses the four-corner method, understand?"

"Understood!" Everyone in the forensic team replied.

The so-called four-corner sorting means that when dealing with piles of physical evidence, it starts from the four corners and gradually advances to the center.In this way, physical evidence will not be missed, and the positional relationship between the original physical evidence can be preserved as much as possible.

After explaining clearly to his own people, Cheng Jinsong called the workers of the garbage dump and explained the situation to them. "Attention everyone, human tissue is very different from the muscle tissue of cattle and sheep. To put it simply, if you find any yellow fat tissue under the skin of the meat in the bag, you must raise your hand and let us know."

Hearing what Cheng Jinsong said, a group of workers looked at each other with different expressions on their faces.Cheng Jinsong also ignored their inner activities, and said: "Then let's start!"

With an order, everyone dispersed immediately.

Shen Yan and Cheng Jinsong walked back to the bag of body parts.Cheng Jinsong carefully took out the body tissue and handed it to Jiang Xin and Wang Zijie, while he picked up the plastic bag and observed it carefully.

Shen Yan asked softly: "How about it, can you detect any clues?"

"It's hard to say," Cheng Jinsong said honestly, "The outside of the garbage bag is too polluted, and I guess the inside of the bag probably won't be able to find the murderer's fingerprints."

Shen Yan frowned, and he looked at Jiang Xin who was at the side again: "Jiang Fayi, where is your side?"

Jiang Xin and Wang Zijie had just laid plastic sheeting on the nearby open space, and Wang Zijie was placing the section of intestinal tissue on it.Hearing Shen Yan's question, Jiang Xin picked up the pelvis and introduced to Shen Yan: "Look at Team Shen, the deceased's pelvis was wide and short, with a round upper mouth and a wider lower mouth. These are typical female pelvic bones. Features. The surface of the upper sacroiliac joint is slightly rough, and it is estimated that the deceased was young, probably between 20 and 25 years old. In addition, judging from the characteristics of the pelvic junction, the deceased did not give birth before his death."

Cheng Jinsong also looked closely, and when Jiang Xin finished speaking, he pointed to the broken bone and asked, "Did the murderer use a knife to dismember the body?"

"It should be a sharp weapon like a knife," Jiang Xin nodded in agreement, "but there are many scratches on the fracture, and the incision is not neat, indicating that although the murderer has certain knowledge of anatomy, he lacks practical experience."

Shen Yan was concerned about another question: "You just said that the murderer might have boiled the corpse, so can it still extract DNA?"

"No problem." Jiang Xin nodded in confirmation, "Although the DNA double helix may unwind when heated, it will restore its double helix structure as the temperature cools down. Moreover, the murderer may not be able to dissociate all the intestinal tissue. Heated to a high enough temperature, I believe that DNA can be extracted."

"You can rest assured about these technical matters." Cheng Jinsong also said, "With DNA, and cross-comparison of missing persons, it should not be too difficult to find out the identity of the deceased."

Only then did Shen Yan feel a little relieved, and then he thought of another question: "Can you judge the death time of the deceased?"

"This is more difficult." Jiang Xin shook his head. "Only these two parts are present, and they are not very directional in confirming the time of death. Especially since these tissues have been treated with high temperature, it is difficult to confirm with general corruption. But when I get back to the bureau, I will test and analyze the contents of the small intestine, hoping to find something."

"it is good."

Sorting and checking is a very time-consuming and tiring task. Everyone needs to remove the bags of garbage from the car, disassemble them, and confirm whether there are suspicious items inside.Although it was still spring, the temperature at noon was close to 20 degrees. Everyone was wearing protective clothing and masks, and they were sweating profusely after a while.Moreover, the smell of this garbage is really unpleasant. Even through a mask, the stench will still penetrate into the nose from every gap. Every breath is a test and torture.

After being busy like this for a while, Su Mohan suddenly heard Su Mohan shouting: "I found something!"

Everyone raised their heads immediately when they heard the words, and saw Su Mohan standing up from a pile of rubbish. He walked towards Cheng Jinsong and said, "Brother Jin, Sister Jiang Xin, come and have a look!"

In Su Mohan's hand was a small piece of muscle tissue—it was half the size of an adult's palm, and there were some light-colored sticky things between the skin and the muscle, just like cooked chicken with butter thrown away by the back kitchen of a restaurant.

Seeing this, both Cheng Jinsong and Jiang Xin changed their colors instantly.Jiang Xin hurriedly took distilled water to wash away the pollutants on the surface, and then she observed it carefully, then suddenly raised her head: "The texture fibers are thicker, it should be human flesh."

"Everyone!" Cheng Jinsong immediately pointed to the pile of garbage and ordered, "Look here first, there must be more inside!"

Hearing this, everyone rushed from everywhere immediately, and plunged into the garbage dump at the same time.Soon, someone else found similar scattered muscle tissue.Everyone became more and more anxious—if there were scattered muscle tissue, it meant that there was at least one concentrated corpse in this pile of garbage!

After half an hour.

"All the internal organs of the deceased are here, heart, lungs, stomach, liver, kidneys... including the uterus." Jiang Xin pointed to the various human organs placed on the plastic sheet and introduced, "All these organs and tissues should be treated Boiled or washed at high temperature, the surface has different degrees of high-temperature denaturation. In addition, there are a lot of skin and muscle tissue," she said, pointing to a pile of minced meat on the right side, "preliminary estimates, there should be a lot at 1000 yuan."

"It should be more than 2000 yuan." Shen Yan said - the way the murderer handled the corpse was almost exactly the same as the murder case 20 years ago.

"I think you should call Bureau Wang after you go back." Cheng Jinsong said to Shen Yan.Shen Yan nodded with a serious face.

——The demon from 20 years ago reappeared.
