Jiang Ruiheng instructed Liu Qingyuan to drive the boat to the corpse, and then put on gloves and began to salvage the corpse. It's just that the range of activities on the ship is limited, and Jiang Ruiheng is a little unable to exert his strength.

"Here's a hand." Jiang Ruiheng greeted without looking back.

Hearing this, Fang Liyuan and Jiang Li, who were sitting behind him, both subconsciously dodged back - it wasn't that the two of them were timid, but the appearance of this corpse was a little too disgusting.

"I'll do it anyway." Li Jiayu said, put on gloves and walked to the bow of the boat.

Hearing Li Jiayu's voice, Jiang Ruiheng turned his head, and then raised the corners of his mouth in satisfaction. Li Jiayu gave him a light smile back, bowed his head and began to work.

On the other side, Cheng Jinsong and Shen Hao were also busy. Shen Hao opened the big bag he had been carrying, took out a bunch of parts that didn't know what function he had ever had, and began to assemble them.

"What is this?" Shen Yan asked.

"Underwater sounding camera. It can move underwater and take pictures. Shen Hao said and handed a pad-like monitor to Cheng Jinsong: "As soon as Brother Jin heard that the body was found in the water hole, he asked me to bring this thing." ”

As soon as Shen Hao's words came out, everyone was interested and turned their heads one after another. With incredible surprise in his eyes, Shen Yan asked, "You still have such a magical thing?" ”

Cheng Jinsong smiled: "Let you open your eyes." ”

As he spoke, Shen Hao's side had already completed the assembly. Now in his hands is a small machine in the shape of an octopus - the top half of which is a round camera, and there is a light above the camera; Underneath the camera is a small impeller, which is supposed to be responsible for movement in the water. A pair of slender iron pliers protrude from both sides of the impeller to pick up what you want to clamp. This "little octopus" is connected to the monitor in Cheng Jinsong's hand through the long connecting cable at the tail.

Shen Hao pressed the button above the camera, and the small light on the camera lit up. At the same time, the monitor in Cheng Jinsong's hand also immediately had a picture.

"Well, the data transmission is normal," Cheng Jinsong checked the picture, tried to manipulate the handle again, and when he saw that everything was normal, he nodded to Shen Hao: "Throw it down." ”

Shen Hao nodded, walked to the side of the boat, turned on the impeller of the detector, and threw it into the water.

There was a blister on the monitor, and soon, the picture became clear. With the camera's own lights, everything underwater can be seen at a glance, and even the lines on the rock wall can be clearly displayed.

Cheng Jinsong manipulated the remote control stick to let the camera move up and down, left and right underwater, observing the underwater situation in all directions.

At this time, Jiang Ruiheng, who had completed the salvage of the body, also came over, and he looked at the clear picture on the monitor and exclaimed: "This thing is very easy to use!" ”

"Yes, with it, you don't have to toss us. Otherwise, Jiayu would have already gone into the water at this time, who would help you fish up the body? Cheng Jinsong winked at Jiang Ruiheng.

On the side, Li Jiayu, who was sampling the river water, heard it, smiled slightly, and continued to work.

In fact, this instrument is also the latest purchase by the forensic team. Cheng Jinsong saw foreign counterparts using this thing when he was in a meeting abroad, and he felt good, so he also applied for one after he came back, and it just arrived in the past few days. In the past, when there was no such thing, once there was something that needed to be forensic underwater, someone needed to go into the water. And the best swimming skill in the entire forensic team is Li Jiayu, so this work was all his. Danger or anything aside, even changing clothes back and forth and carrying an oxygen cylinder is enough to torment people. Now with this instrument, it is much easier, and when people are on shore, they can detect everything under the water clearly.

Seeing that little thing going farther and farther underwater, Jiang Li asked Cheng Jinsong: "How far can it go?" ”

"In principle, the transmission line can go as far as it can." Cheng Jinsong said: "Our transmission line is 50 meters long, and we hope it will be found in this range. ”

However, the end result was a bit disappointing. Although the entrance of this waterway is not large, the depth inside is quite long. The camera walked 50 meters below, but found nothing but a small strip of rags.

"It seems that the body has drifted from the innermost place. It is estimated that the earthquake shook something open, and it drifted over. Cheng Jinsong said to Shen Yan while retracting the detector: "It's not good, it may come from the source." ”

Shen Yan nodded, turned his head and asked Liu Qingyuan, "What is the source of this underground river?" ”

"It's the Yushui River next to it." Liu Qingyuan said: "The Yushui River enters the mountains from the east, forming this underground river, and then exits from the west. ”

Shen Yan nodded, and then asked, "When you found the body, it was in this location?" ”

"It was a little closer to the hole."

"Was there anyone around?"

Liu Qingyuan thought for a while and shook his head: "You should have seen the sign outside when you came, after the earthquake two days ago, the leaders were afraid that the earthquake would have an impact on the water hole, so they have not been open to the outside world for the past few days." That's where we came in today to check. Only Xiao Wang and I have come in this water hole today, until you come in. ”

"Is there any other entrance to this cave?"

"Nope." Liu Qingyuan shook his head: "It's just such a waterway, all the boats come in the same way and go out the same way - oh yes, there are a few places in the middle that are a little forky, but the last exit is only the one we came in." ”

Shen Yan nodded, he looked at the corpse on the bow of the boat, then at the closed and gloomy surroundings, and slowly wrinkled his brows.

Coming out of the Yushan Water Cave, the serious crime team questioned the staff member surnamed Wang again, and the statement obtained was almost the same as Liu Qingyuan's. Cheng Jinsong consulted Director Kang again, and Director Kang also said that the source of the underground river in the Yushan Water Cave is the Yushui River. So everyone went directly to the Yushui River. The group inquired along the river, but no one felt how the Yushui River had changed after the earthquake, and no one had seen a corpse or the remains of bones. This corpse seems to have appeared out of thin air, I don't know the race, I don't know the gender, and as for the cause of death, it's even more mysterious.

Because there were no eyewitnesses or the scene of the crime, the only way to get clues was forensic evidence and forensic medicine. The next day, the entire forensic team and the forensic doctor Jiang Ruiheng were all engaged in intense busyness, Jiang Ruiheng performed an autopsy, Shen Hao restored the face of the corpse, and Cheng Jinsong and others examined other evidence to determine the time of the corpse's murder. The Crime Squad had nothing to do for the time being, so they had to gather in the offices of these people and wait for the results.

In the evening, before leaving work, the conference room of the Serious Crime Unit.

"Let's get to know this Mr. Anonymous first." Jiang Ruiheng opened with such a sentence. He nodded to Shen Hao, and Shen Hao clicked the mouse, and a simulated picture of a young man's face immediately appeared on the big screen.

"This is our deceased," Jiang Ruiheng pointed to the big screen and said, "Yellow race, male, 173-175cm tall, should be between 20-24 years old." This is a photograph of his face reconstructed. Jiang Ruiheng handed the printed face restoration map to Shen Yan: "You can use it to find out who the deceased's surname is." ”

Shen Yan nodded and took it, and then asked, "What is the cause of death?" ”

"There was an obvious fragmentation of the back of the skull of the corpse, which should have been caused by a heavy impact. This wound is enough to cause intracranial hemorrhage in the deceased and can be life-threatening. However, the deceased's muscle tissue has almost completely broken down, so it is impossible to know if he has suffered any other injuries. At this point, he seemed to remember something: "Oh yes, one thing is certain, the right tibia of the deceased was broken after his death. ”

"Was it cut down or scraped off in the water?" Fang Liyuan asked.

"The bone section is not neat, it doesn't look like it was cut by someone, it should have been torn off under the action of external force."

Fang Liyuan nodded.

"What about the time of death?" Shen Yan then asked.

"I'll tell you about this." Cheng Jinsong interface. He handed a report to Shen Yan: "According to the director of the park, the water in the Yushan Water Cave came from the Yushui River, so we sampled the water in the Yushui River and the Yushan Water Cave respectively, combined with the temperature difference between the two places for a year, simulated the decay rate of the corpse in the water system, and finally determined that the time of death of the corpse was about 40 months to 33 months, that is, more than three years ago." ”

"Three years ago? ......" Shen Yan looked at the facial simulation on the photo, frowned and said to himself: "Then let's start from three years ago......"

The investigation begins with the identification of the deceased. The Crime Unit retrieved the missing persons records of S City for the past three years, but found no one resembling the deceased. Considering that the body may have been washed down along the Yushui River, the investigation was extended to the relevant cities in the upper reaches of the Yushui River, but no eligible missing persons were found.

“…… Therefore, I plan to send the photos to several surrounding cities tomorrow, and if it doesn't work, I will issue a missing person notice, in short, I must first find out the identity of the deceased. ”

Cheng Jinsong nodded, and then pointed to Shen Yan's chopsticks: "Okay, eat quickly, I'll talk about work tomorrow." ”

Shen Yan had been talking to himself for a while just now, and when he heard this, he reacted, and he smiled: "I'm sorry, I forgot about it as soon as I said it." ”

It has been five days since Cheng Jinsong returned from the south. The first two days were sorted out, and then the murder case was reported, and it was not until today that the two of them had a little free time and went out for dinner together. As a result, Cheng Jinsong just mentioned the case just now, and Shen Yan has been talking about it until now. Thinking of this, Cheng Jinsong shook his head helplessly: "You, your eyes light up when you talk about the case." ”

"you, you're the wolf!" Shen Yan scolded with a smile.

"Seriously," Cheng Jinsong put away his smile and asked with concern: "How is your health, can you go to work?" ”

"It's been a few months? I've been fine for a long time. Shen Yan replied with a smile.

"It's okay, you have to pay attention to your body." Cheng Jinsong glared: "You are seriously injured, even if the bones are grown, your physical condition cannot be restored to the previous state immediately, and you must not work too hard recently." ”

Cheng Jinsong didn't say it, but as soon as he said this, Shen Yan immediately became angry: "You are embarrassed to say it!" Did you tell the guys in our group something? In the past few days, as soon as five o'clock arrives, they will come to urge me to get off work, and I can't leave it. ”

Hearing Shen Yan ask, Cheng Jinsong showed a sly smile: "You never knew that you felt sorry for yourself, so I had to find someone to watch you." Seeing that Shen Yan wanted to speak, he continued: "Don't worry, they are measured, and they will definitely not stop you when they really need to." But you also have to pay attention to your body, and when you can, you should work less overtime and go home more to rest. You don't want to be overwhelmed when you catch thieves in the future, do you? ”

Cheng Jinsong was reasonable, not to mention that Shen Yan himself also found that his body felt more tired than before the injury when he got off work recently, and he really shouldn't be reckless.

"Really, I'm their leader, why do they listen to you so much? ......" Shen Yan muttered.

"Haha, you're so blushing, after all, I've been with them for more years than you."

Shen Yan pursed his lips and continued to eat with his head bored.

Looking at Shen Yan's rare childish appearance, Cheng Jinsong instantly laughed, and then he remembered something again: "By the way, I brought you a gift back." ”

Shen Yan was stunned. I saw Cheng Jinsong take out a delicate black wooden box from his bag and hand it to him. The box is about a palm's length and looks very classy.

Cheng Jinsong smiled and said to Shen Yan, "Open it and take a look." ”

Inside the box is a black leather belt, the leather is soft and well made, and it is definitely a good thing.

"How's that, do you like it?"

Shen Yan's heart swelled with a warm current of happiness, he nodded, but said, "It's definitely not cheap, right?" Don't spend this kind of money next time. ”

"The money that should be spent still has to be spent." Cheng Jinsong smiled: "I used to hear those little girls say that if you like a man, you have to give him a tie, which means to tie people to you." But you don't wear a tie either, so it's useless to give that thing, so I changed it to a belt. If you tie it, even if you are tied by me," Cheng Jinsong held Shen Yan's hand, looked at Shen Yan's eyes, and said sincerely: "I won't be able to run in the future." ”

Shen Yan felt the heat coming from his palm, and he squeezed Cheng Jinsong's hand emotionally.

Cheng Jinsong smiled and raised his eyebrows: "How is it?" Why don't you go and change it now? ”

Shen Yan was stunned for a moment, and then laughed: "You don't have to be in such a hurry, right?" ”

"It's okay, let's try it......"

Just as the two were talking and laughing, Shen Yan's mobile phone suddenly rang. Shen Yan took out his mobile phone and looked at it, and his face suddenly changed.

"What's wrong?" Cheng Jinsong asked, poking his head over. I saw that on Shen Yan's mobile phone screen at this moment, "the number cannot be displayed" was displayed......

- Such a call is generally not good news.

The two looked at each other, then got up separately and walked to a quieter place on the side.

Shen Yan picked up the phone: "Hey? ”

"Hello, Captain Shen." On the other end of the line was a familiar voice.

Shen Yan was taken aback: "Li Guangbei?!" ”

Cheng Jinsong was also taken aback, and immediately put his ear to Shen Yan's mobile phone.

A chuckle came from the other end of the phone: "Hehe, Captain Shen has good ears, he can actually hear it." ”

"What are you looking for from me?"

"Don't be nervous, I'm doing my duty as a good citizen today to provide clues to your police." Li Guangbei said.

"Really? What clues do you have to offer? ”

"Did you find a nameless corpse recently?"

Hearing this, Shen Yan was slightly surprised: "How do you know?!" ”

"You don't have to worry about this, I just want to tell you that that person's name is Xu Peng, and he used to be a student at S University. The rest is up to you. ”

Hearing Li Guangbei say this, Shen Yan's vigilance in his heart became a little higher, and he asked quietly, "How did you know about these situations?" ”

Hearing Shen Yan's vigilant voice, Li Guangbei laughed: "Captain Shen, don't worry, his death has nothing to do with me at all. He restrained his smile as he spoke: "Actually, I'm looking for him too." ”

"You're looking for him? What to do with him? ”

"That's my business." The answer is an understatement.

Shen Yan held the mobile phone and didn't speak, the two were in such a stalemate, but no one hung up.

After a while, Li Guangbei spoke again: "Captain Shen, how about we make a deal?" ”

"What deal?"

"Didn't you ask me last time, what happened to Zhao Gang's death?"

Hearing this, Shen Yan suddenly clenched his mobile phone.

Through the receiver of the mobile phone, Li Guangbei's voice came clearly: "As long as you find out the cause of Xu Peng's death, I will tell you the truth of that matter......"
