Chuanshan

At six o'clock in the afternoon, the conference room on the first floor.

Sun Mingrui introduced: "The bricks for the new wall are standard building materials, which have no particularity and no directionality. The mortar used for the wall has not extracted any useful clues. A set of shoe prints extracted from the interior did not come from The deceased. According to the footprint measurement, the owner of this shoe print is about 170 tall, male, with a thin build, and the shoe size is 42. It is speculated that he is wearing very cheap pirated sneakers. The center of gravity is the right foot, and the left foot is full. There is an oval-shaped hyperplasia at the head of the third metatarsal in the middle of the metatarsus, commonly known as corns. But this person should not be the murderer."

"Why are you sure this person is not the murderer?" Bai Ze asked.

Sun Mingrui explained: "Because this is not a simple de-layered shoe print. The so-called de-layered shoe print means that the sole of the shoe took something away at the scene. Simply put, there is dust on the ground in the house. You wear shoes and step on it to leave something behind." After the shoe prints were removed, it was the soles that took away the ash. But at our site, there was still a layer of ash on the shoe prints. That is to say, this person entered during the time between the incident and the discovery of the body. According to the analysis of the dust at the scene, it was probably half a month after the scene was cleaned up. In addition, judging from his footprints and the remaining fingerprints in the house, this person is very likely to be a A thief, he came into the house to steal things, but because he was wearing gloves, his fingerprints could not be extracted. In addition, the door lock has been picked, so I speculate that the probability of this person being a thief is very high. If it is If the murderer returned to the room to look for something, he should not forget to clean the room, nor would he wander aimlessly in the house."

Qiao Chen nodded thoughtfully and said, "It makes sense, but the suspicion of this person cannot be completely ruled out. What else do you find?"

Sun Mingrui went on to say: "A very small amount of powdery substance was extracted from the corner of the house, and it was confirmed to be methamphetamine by the poison room inspection. It was exactly the same as the proportion of methamphetamine in the bottle we found in Meng Jianguang's house before. We can confirm that it is the same batch. In addition, I also found a circular trace on the cabinet where the methamphetamine was found. After comparison experiments and mold culture experiments on the bottle body and cabinet board, it was proved that this trace was consistent with the bottle found in Meng Jianguang’s home, which can be confirmed The bottle in Meng Jianguang's house was taken from here."

Pang Guanglong said excitedly: "That is to connect these two cases!"

"Yes." Yan Lan said, "The comparison of DNA and fingerprints just now confirms that the deceased we found today is one of the suspects they had not found before in the anti-narcotics. He is also the owner of Zhang's private kitchen that Meng Jianguang saw. His name is Zhang. Ge, nicknamed Mozi, is 35 years old. His last contact with anyone was on June 6th, and no one has seen him since then. Did the trace inspection find anything else?"

"That's all for now." Sun Mingrui replied.

Yan Lan nodded, then turned to look at Su Xing and said, "Tell me about the condition of the corpse."

"Okay." Su Xing said while sitting on a chair, "The length of the corpse is 173 centimeters. The time of death is estimated to be about one and a half months, which is consistent with the time of his disappearance that Team Yan said just now. The corpse's plaques are deposited on the back and lower limbs. The plaques are shallow, and the light red liquid can be seen flowing out of the interstitial space and cannot be erased when the plaques are cut. It is the plaques in the diffusion stage. It is inferred that they were moved to the current position within 12 hours after death. According to the stomach of the corpse According to the analysis of the contents, the last meal of the deceased had pork and beef, and he also drank red wine. According to the location of the food and the degree of digestion, the time of death should be about 24 to 2 hours after the last meal. The main organs of the deceased were not Pathological changes of fatal diseases, excluding sudden death from sudden illness, no signs of mechanical injury, excluding traumatic death, no signs of mechanical asphyxia, and not suffocation death. The deceased had a history of drug abuse, but the autopsy signs did not meet the characteristics of drug overdose, No other toxins were detected in the liver or kidney of the deceased, so... so the cause of death cannot be determined for the time being."

After Su Xing finished speaking, the conference room fell into silence, and the forensic doctor said that the cause of death could not be determined, either because the forensic doctor's level was not up to the mark, or he encountered a very difficult situation.Su Xing was Wang Jun's apprentice, and he was the best in the criminal department except for Wang Jun. Everyone knew that now that Su Xing said the cause of death was unknown, even if Wang Jun came back, he might not be able to find out the cause of death.

Yan Lan poked the table with a pen and said, "Fatty, tell me about your situation."

"I found nothing here." Pang Guanglong shook his head and said, "I ran with Qingyuan all day, but found nothing. Now Qingyuan is contacting the former tenants of Meng Jianguang's yard to see if they can find something. What."

Yan Lan: "Now the two lines of monitoring and food delivery companies are basically impossible to get through. We can only rely on integrating other clues. Sun, you give Bai the characteristics of the characters deduced from the footprints at the scene, and ask him to investigate."

"Alright Team Yan."

Yan Lan thought for a while, then continued: "Fatty, you still take Liu Qingyuan to investigate Meng Jianguang's side. Lin, ask the technical detective to see if you can call up other municipal surveillance to see if there is any data that has not been overwritten that can be recovered. Recover. Bai, go and investigate the person who entered Zhang Ge's house in the middle, and also pay close attention to the matter of finding the remaining body parts. The Criminal Division continues the work at hand, confirming the death tool of the unknown corpse and Zhang Ge's cause of death You've worked hard today, and you should rest when you go back. This case is a protracted battle, and we can't just get through it. Qiao Chen and Su Xing will stay here for a while, and the others will go back to their respective homes and talk about it after recovering their spirits."

After everyone left the conference room, Yan Lan looked at Qiao Chen: "You can talk now."

Qiao Chen opened the notebook and said, "Haisun Medical Devices Company's HS-AL102 and AL103 stretchers have sold a total of 23 sets in the city's retail market this year, and the whereabouts of 20 of them have been confirmed, and the suspects have been ruled out. .Besides, I have checked all the franchised stores where they distribute the goods, and the numbers are correct. Most of them are still in packaging and have not been used at all. Do you need to check the sales records of previous years? "

Su Xing shook his head: "The aluminum alloy stretcher used by their company was HS-AL101, which does not match the marks on the back of the corpse. Unless the murderer was carrying a stretcher from other places to kill, if the last three sets are also ruled out..."

The three of them knew what Su Xing didn't say, and the case was ultimately directed at one of their own people. The best situation now is that someone in charge of logistics lent the stretcher to others for public benefit, and the worst The current situation is that this drug-related murder was done by insiders.

"Okay." Yan Lan patted Qiao Chen's shoulder, "Don't worry about it, we will definitely find it."

Qiao Chen stood up from the chair and said, "If I don't go home today, Old Comrade Qiao will let the dogs bite me. Boss, don't look for me if the sky falls tonight!"

Yan Lan hated his extremely bad excuses, but since he didn't want to be a glowing light bulb, Yan Lan had no choice but to suppress his thoughts of hurting him, and waved at him magnanimously: "Ask our dad good!"

"Thank you for old Joe—"

When Qiao Chen left, Yan Lan raised her hand and shook Su Xing's eyes: "Okay, let's go home."

"Team Yan, you go back first, I want to check some more information."

"There is a computer at home, so I can check it when I go home. I have to accompany you when you work overtime here." Yan Lan pulled Su Xing to stand up, "Go and change clothes, I will wait for you at the place where I got off this morning."

Yan Lan looked at Su Xing's dazed back, and suddenly felt distressed.The body was there, but the cause of death could not be found, especially when the circumstances of this case were unknown, Su Xing was actually under a lot of pressure.Determining the cause of death is a very important part of a criminal case. Sometimes through the cooperation of the Criminal Bureau, the portrait of the murderer can be roughly inferred, and even directly arrested and solved.Today, when science and technology are so advanced, the autopsy cannot give the cause of death, which is a great setback for any forensic doctor.Yan Lan had long discovered that Su Xing had a stubbornness in his work. Last time, because he didn't expect Li Leilei to die of malignant hyperthermia, he spent a week in the forensic room reading papers on hyperthermia, wishing to put all the related information at home and abroad. Read all the documents before giving up.Now this situation of not knowing the cause of death after the autopsy is probably the most intolerable thing for him.

Su Xing sat in the co-pilot, Yan Lan threw him a pack of chocolates and said, "Sweets help you feel better."

"Thank you." Su Xing unwrapped a piece of chocolate and stuffed it into his mouth, "Team Yan, can you go to my house first? Some information can't be found online."

"Okay." Yan Lan stepped on the accelerator and drove the car out.

Because the odd and even numbers are restricted in the city, the evening rush hour is not very congested, so soon Yan Lan parked the car at the entrance of Wanming Park.This time Su Xing didn't get out of the car, but said: "Go into the community, I'm afraid I have to take too many things."

Yan Lan followed Su Xing's instructions and parked the car downstairs. He didn't make too many demands, and said to Su Xing: "Call me if you can't carry it."

Ten minutes later, Su Xing went downstairs with a boarding case.While helping him put the suitcase in the trunk, Yan Lan joked, "It feels like helping you move."

"It's not like." Su Xing paused before continuing, "If you want to move, the first thing to move is the mannequin."

Yan Lan smiled and patted Su Xing on the shoulder: "Okay, little hedgehog, don't think about the corpse, let's think about what to eat at night."

"I'm free."

"Then let me make chicken soup with yam, and make fruit salad with pineapple, mango and kiwi, can you?"

"... Captain Yan, you are making too much sense."

Yan Lan snorted softly and said, "Tell me later if you want, I'll make you a set, and I'll give you a seafood feast with pumpkin porridge."

Su Xing: "..."

Yan Lan took out a booklet from the storage box in the trunk and handed it to Su Xing, saying, "Take it and read it in the car."

Su Xing sat in the co-pilot and fastened his seat belt before opening the booklet. As he flipped through the pages, he asked incredulously, "This is all from your family? Are you too rich?"

"I'm not asking you to lament this, I'm asking you to see what you want to eat."

"I want to eat something down to earth." Su Xing closed the booklet and said.

"what?"

"Let's eat the skewers." Su Xing asked hesitantly after finishing speaking, "Do you not eat this kind of thing?"

"Heh." Yan Lan smiled, "Isn't it easy to want to masturbate?!"

Ten minutes later, Yan Lan parked the car outside the most famous snack street in Pinglu.He led Su Xing to turn left and right, walked outside a very inconspicuous door, and shouted at the boss inside: "Old Qi! Two people! The old place!"

The person Yan Lan called Lao Qi was named Qi Zhengyi, and he was the owner of this food stall.When Qi Zhengyi saw Yan Lan, he trotted out immediately: "Officer Yan hasn't been here for a long time! Today with Joe... Oh, it's not Officer Qiao, this one is a little strange, this is...?"

"My friend." Yan Lan took the menu from Qi Zhengyi, "Twenty skewers first, ten spicy ones and ten non-spicy ones, and we'll call you after we've selected the rest."

"Come on! Choose slowly!" Qi Zhengyi said and ran to the side to place an order.

Yan Lan handed the menu to Su Xing, and asked, "Why are you in a daze? Hurry up and see what you want to eat, and order quickly while there are few people, or the food will be slow to serve when there are too many people."

"I thought you would say I was your colleague."

"A colleague who lives in my house?" Yan Lan stretched out her finger and pointed at the menu in front of Su Xing, "Old Qi's baked bun slices are a must, you must try it. I ordered twenty skewers just now. You look at something else."

Su Xing asked, "Can I drink?"

"Drink, you don't drive."

After more than ten minutes, a bottle of beer, a pot of "Flower and Hair", and a bunch of skewers were placed in front of the two of them.

Yan Lan looked at the mountain-like string in front of her and said, "I have to run on the treadmill for an hour tonight."

"It's okay to eat once in a while." Su Xing picked up a bunch and put it to his mouth, "I thought a rich person like you wouldn't eat these things."

"I thought you forensic doctors would study which part it was before eating skewers."

Su Xing was once again amused by Yan Lan's boring joke, and he said, "I'm not that perverted. Besides, I'm a forensic doctor and not a veterinarian. At best, I can tell whether the ribs are artificial."

"What do you think?"

"Look at the gloss and curl. To put it simply, the artificial ones are the products on the assembly line, and they all look the same; but each piece of real beef ribs is different." Su Xing said, holding the beef ribs in his hand, "It's true , the boss is quite honest."

Yan Lan picked up a bunch of bars and looked at it, then said, "You still look good when you smile."

"I..." Su Xing shook his head slightly, "I can't find the cause of death, so I really can't laugh."

"We haven't found the source of the corpse yet, so we can't laugh anymore?" Yan Lan picked up the peanuts in the basin, "Sometimes not everything goes as we want, especially in cases. Although There is a lot of pressure to solve a case, but you can’t be pressured first. If the mentality of the investigators collapses, the case will be even more impossible to investigate.”

"I know." Su Xing broke off a slice of toasted steamed buns, "But as a forensic doctor, I can't detect the cause of death. That feeling...is like you can't hit a fixed target right in front of you with a gun. People rub fire."

"Understood." Yan Lan pushed the pot with only edamame left over to Su Xing, "But the case is not yet desperate. We have many clues, but it just takes time. The suspect killed someone with a purpose, not Committing crimes randomly, this has already set a scope for us. In addition, Zhang Ge is a suspect on the anti-narcotics side, and there are a lot of information and clues about him, we will definitely be able to find out."

Su Xing took a sip of beer and reached out to take peanuts from Yan Lan, but Yan Lan grabbed his wrist: "Don't eat it!"

"It's okay to eat one."

"No." Yan Lan pushed Su Xing's hand back to the table, "Don't touch it if you have allergies, I don't want to see you suffer."

Su Xing had no choice but to grab the edamame in front of him, and said angrily, "Stricter than my master."

"You've been sick five times in front of me, and I don't want to see the sixth time."

"How can there be so many?!"

"A stress-induced fever, vomiting while holding my toilet, asthma, hypoglycemia and almost passed out, plus this morning..." Yan Lan looked directly at Su Xing, "I haven't counted it for you yet. The two times in the Arrow Sea and the Pingqiu area."

"..."

The light in Yan Lan's eyes seemed to have some kind of calling, so that Su Xing couldn't move his eyes away. There was a lot of people around, but the two turned a deaf ear and looked at each other quietly in this noisy food stall.Su Xing was a little greedy for such moments, as if it was more comfortable to look at Yan Lan in such a noisy environment.

"Stop!" A roar from the side broke the delicate atmosphere between the two.
