Criminal Investigation Notes

This busy, has been busy until more than 10 p.m., Song Wen drove to the residence, just about to take off his coat, Lu Si Yu said: "go to take a bath first, body is full of nitrite, be careful of poisoning, not good for your health."

Song Wen took off his coat in his arms. "Do you want to come with me?" After saying that, he felt uncomfortable and added, "anyway, there are many toilets in your house."

"I'm very careful. I can wash my hands later. It's you who helped them carry the bodies. " He thought about it and said, "by the way, put your clothes in the washing machine, and don't let the wolf touch them."

Song Wen responded and dodged the dog. He went to the bedroom to get his clean clothes. He went to the bathroom and washed them carefully.

Since Song Wen moved in, there have been some changes in the layout of Lu Siyu's study. He likes to use notebooks, so he uses a horizontal table on the side, leaving the theme to Song Wen. This arrangement makes him feel like two people sitting in the Municipal Bureau office.

Song Wen comes out of the bathroom, comes to the study and turns on the computer. At this time, Zhu Xiao has called up the missing man records of the past year around Nancheng city. Song Wen printed the data, and Lu Si Yu was sitting on the side, ready to copy the field investigation report to the book. Looking at Song Wen, he looked at the materials and reached out and said, "show me?"

Song Wen handed the stack of paper to the past: "now the autopsy has not been completed, the information is too little, may be useless."

But Lu Si Yu didn't care much about it. One by one, he turned it over and said, "at least you can check it out first."

Song Wen said, "shall I go and warm you a glass of milk? It's good for sleep. "

Lu Si language shakes his head: "brush a tooth."

Song Wen looked at the time: "but it's almost eleven o'clock. Even if you are more dedicated, you can't endure like this."

Lu Si Yu lowered his head and continued to look at it. He held his cheek with his hand and did not raise his head. "You asked Zhu Xiaoda to retrieve these files in the evening, just to stay up late to read them tonight?"

He knows Song Wen again. However, the case has not been solved. He always puts the case first, which is more important than eating and sleeping. At this time, he pretends to be free and relaxed, but only to coax him to sleep.

A thick stack of missing records, each of which represents the expectations of relatives. The dead is a human life. If you can solve the mystery one minute earlier, you can close the case as early as possible. How can you make people relaxed at such a time?

Song Wen broke his mind, took back his hand and sighed, "I can still sleep even if I lie in bed at two o'clock. Can you compare with me? " He had planned to talk to Lu Siyu about Xu Changying's digging up the wall. After Lu Siyu fell asleep, he would finish the screening work himself. But now he saw that Lu Siyu was so absorbed in the case that he didn't seem to be ready to leave.

Lu Si language eyebrows slightly curved, or refused: "you let me see for a while, it's too early, I can't sleep."

Song Wen couldn't help but snatch half of it from his hand and said, "two people should check it quickly. When you're done with it, you'll go to bed for me

Lu Si Yu had no objection this time. He hung his head and habitually put his thumb to his lips and bit his nails to have a close look.

Song Wen, with more than ten pieces of information in his hand, began to investigate the factors such as age, height, body shape and missing time. After reading more than ten pieces of data, there were always one or two items that could not match the victims.

Song Wen was so absorbed that he read it quietly for about an hour and finally ruled out all the possibilities. He put down the data and stretched out his body and said, "I've finished reading it. It's not true. It seems that this bacon brother is still very difficult to find. "

As soon as Song Wen finished speaking, he looked up and saw Lu Si Yu with one hand on his head, his eyebrows closed, his sharp chin hanging down, and he was already sitting there asleep. Song Wen, afraid of disturbing him, got up and looked at the information on the table. The records were almost as good as they were marked by him.

Song Wen thinks, this man is really, just want to work, do not want to go to sleep is he, now sitting at the table asleep is also him.

Song Wen stood opposite the table and looked at the sleeping face of the landing secretary. His skin was white and his eyebrows were as delicate as ice. Song Wen didn't want to wake up when he saw Lu Siyu. He just walked over and turned his swivel chair. He took a look at him in his arms. Song Wen held him up with both arms.

When Lu Siyu was half asleep and half awake, he suddenly felt light. He knew that he was held by Song Wen and could smell the man's body. However, his eyelids were too heavy to lift up. He gave a low voice. The sound was like a kitten barking. Song Wen held him and put him on the bed in the bedroom. Afraid that he would wake up, Song Wen looked at the face of Lu Siyu Qingjun, but his eyebrows were still closed. Then he held his head down carefully and covered him with a quilt.

Song Wen looks down at the sleeping face of Lu Si Yu. He thinks in his heart that if he can do this all the time, it seems good.

The next morning, as usual, the morning meeting was held by all departments. The small meeting room was occupied by Xu Changying's team. They had to use the forensic medicine room to meet each other temporarily. Because it was too late last night, and the identity of the body was not determined, Lin xiuran did not transport the body to the funeral home, but directly parked it in the forensic room.Song Wen rubbed his nose as soon as he entered the door of the forensic medicine room. The corpse was left here overnight. There was a faint smell of sea salt in the air.

After a short time, everyone arrived.

All the material evidence went out of the field today, leaving the photos and all kinds of materials. Several criminal policemen and Lin xiuran sat down beside the corpse that had been turned into a mummy for a long time and held a serious meeting.

Song Wen got to the point: "last night, Lu Siyu and I had checked the latest missing person records. In the missing person file, there was no match with the age and height of the deceased."

Lin xiuran said: "my autopsy here has also been completed. The male of the deceased, aged between 25 and 26, is about 180 in height. The DNA and fingerprints of the deceased are not recorded in the relevant database, which means that the deceased may not have a criminal record before his death. In other cases, the time of death was about six months ago. The cause of death was a knife in the chest. This knife stabbed the lung and should die soon. In addition, yesterday, we found that there was a scar on the abdomen of the deceased. After dissection, it was found that it was an operation wound. The dead person had no gallbladder. He may have had cholecystectomy. He had cancer in his body. That is to say, this is a young patient with advanced cancer. "

"Advanced cancer? This man doesn't have a few days to live? " Fu Linjiang frowned slightly when he heard this. Such dead people are rare in previous cases. "What deep hatred does it take to kill a terminally ill person? After waiting for a few months, he may die. Why end his life in this way? "

According to common sense, such a terminally ill patient should be lying in the hospital or enjoying the last time with his relatives, but he was killed and left dead in a chemical plant.

Song Wen was also confused: "this man is not a missing person, and he has not been recorded. He died for such a long time and did not report to the police. This is very strange."

No family, no friends, no police records, no information, this person alone, as if abandoned by the whole world. No, he's still connected to the world. That's the killer. He left him in the old chemical factory

Zhu Xiao looked at the corpse lying on one side sympathetically, and thought of a possibility: "is it possible that this man has been living in a foreign country, and his relatives think that he has not returned from a business trip?"

Old Jia shook his head: "it's all advanced cancer. What's wrong with it How can such a critical patient come out and run around

Zhu Xiao continued to infer: "if it is his relatives who regard him as a burden, what would he like to see? Who would you like to meet He came to Nancheng alone, or Cross regional crimes or cross regional corpses? "

Fu Linjiang said, "it is possible. But in this case, we have to apply for collaborative investigation from all over the country, and things will become a lot more troublesome... "

"The murderer put the body there, indicating that he had a means of transport and was very familiar with the local area. Cross regional transportation, for the murderer, increased risk It is best to consider this possibility after completely excluding all factors. " When Song Wen finished speaking, he turned his head and looked at Lu Si Yu holding a pen in his hand and staring at the corpse in front of him.

"Lushi language?" Song Wen called him, "what do you think?"

Lu Si Yu gave a sound, which just seemed to wake up. He was a little absent-minded. He fell asleep very early yesterday, but he woke up before five o'clock. His stomach ache till dawn. Now the pain in his stomach is so bad that he can't concentrate. It seems that since the last gastric bleeding, his stomach attacks have been more frequent than before. No matter how careful he is, it is useless. Now that the painkillers are taken away, the effect of those other drugs is negligible.

Feeling Song Wen's eyes cast, he didn't want to worry Song Wen. He put his hand under the table, leaned forward slightly, and put his whole hand under the table against his abdomen. He took a breath and straightened his way of thinking: "can we start with the illness?" He wanted to say more, but with a twist in his stomach, he bit his teeth in a hurry, pressed a low voice in his throat, and lowered his head, hoping that Song Wen would not find out his abnormality.

"That's a way of thinking." Lin xiuran understood and agreed: "in this city, cancer is still a minority. We can check all the patients with related diseases in the city. Male, 25 years old, who have undergone cholecystectomy in the past few years, may have records."

Song Wen said: "let's check it out first. Isn't the big database of technical investigation almost completed recently? "

Referring to the big database, Zhu Xiao, who has an interface with the technical investigation, immediately shows a look of disgust.

With the rapid development of the Internet, the police's big database has been built for a long time. Nancheng city is in the front in these aspects. The whole database is extremely large, with a lot of input work. In cities with a population of millions, it is necessary to achieve birth information, household registration information, death information, medical treatment, real estate, mobile phone, bank card, license plate number, and various ticketing letters It is difficult to complete almost all the related work.

One of the biggest difficulties is that there are many errors in the input. The speed of information generation is much higher than the speed of import, so that the content of police big database lags behind a lot.

However, the record of the operation done a year ago should be able to be checked out. Zhu Xiao took his laptop and entered the Nancheng police database with his password. After inputting several key information, a symbol next to him began to rotate, indicating that he was in the process of screening.People hold their breath, wait for a full ten seconds, the screen flickers, Song Wen thought the results, but see a progress bar on the right side, the number on the top jumped from 0% to 1%

Zhu Xiao sighed, "sometimes, I really want to change their program again."

Fu Linjiang laughed bitterly.

Old Jia got up and said, "I'll get my cup."

Song Wen calculated it. If it was calculated preliminarily, it would take a few minutes. He said, "let's have a rest first."
