Criminal Investigation Notes

I was busy until ten o'clock in the evening. Song Wen drove to the residence, and just about to take off his coat, Lu Siyu said: "Go to the bath first. You are covered with nitrite. Be careful of poisoning, which is bad for your health. "

Song Wen wrapped the coat he had just taken off and held it in his arms, "Do you want to be together?" After speaking, feeling awkward, he added, "Anyway, there are many bathrooms in your house."

Lu Siyu said: "I'm very careful. I can just wash my hands later. It's you who helped them move the corpses." He thought about it and said again, "By the way, put your clothes in the washing machine. The wolf met."

Song Wen replied, avoided the dog that rushed over, went to the bedroom to get a change of clean clothes, and went into the bathroom. Song Wenzai carefully washed it again.

Since Song Wen moved over, the layout of Lu Siyu’s study has changed a bit. He likes to use notebooks, so he used a horizontal table on the side and left the main position to Song Wen. This arrangement makes it feel harmonious. The two people in the city bureau office are sitting in similar positions.

Song Wen came out of the bathroom and turned on the computer in the study. At this time, Zhu Xiao had retrieved the records of missing men in the surrounding areas of Nancheng City in the past year.Song Wen printed out the information, and Lu Siyu was sitting on his side preparing to transcribe the site survey report on the notebook. Watching Song Wen flip through the information, he stretched out his hand and said, "Let me see?"

Song Wen handed the stack of paper over: "The autopsy has not been completed yet, and there is too little information, and it may be useless."

Lu Siyu didn't care too much, looking through them one by one: "At least we can check it out first."

Song Wen said, "Shall I warm up a cup of milk for you? It will help you sleep."

Lu Siyu shook his head: "I brushed my teeth."

Song Wen looked at the time: "But it's almost eleven o'clock, no matter how dedicated you are, you can't keep going like this."

Lu Siyu lowered his head and continued to watch. He put his cheek in his hand without lifting his head. "You asked Zhu Xiaoda to retrieve these files at night, isn't it just to stay up late to read it by yourself?"

He knows Song Wen better, but if the case is not solved, he always put the case first. It is more important than eating and sleeping. At this time, he pretends to be nothing and relax, but to coax him to sleep.

A thick pile of missing records, each one represents the expectations of their loved ones. The death is a human life. If the mystery can be solved one minute earlier, the case can be closed one moment earlier. How can people easily get it?

Song Wen was disturbed by him, retracted his hand, and sighed: "I, even if I lie in bed at two o'clock, I can still fall asleep. Can you compare with me?" He had planned to talk to Lu Siyu. Talking about Xu Changying's digging the foot of the wall, after Lu Siyu fell asleep, he would finish the screening work by himself, but now he sees Lu Siyu devoting himself to the case, and it doesn't look like he is about to leave.

Lu Siyu's eyebrows curled slightly, and he refused, "Let me watch it for a while, it's too early for me to sleep."

Song Wen couldn't help but grabbed half of him from his hand and said: "Two people check, always faster. When you finish reading, you can go to bed obediently."

Lu Siyu had no objections this time, and habitually put his thumb to his lips, biting his nails and looking closely.

Song Wen took more than a dozen pieces of information in his hand, and began to investigate factors such as age, height, body type, and missing time. After reading more than a dozen pieces of information, there were always one and two that were incompatible with the victim. Too much match.

Song Wen focused on watching it quietly for an hour, and finally ruled out all the possibilities. He put down the information and stretched out and said, "I have finished reading it, it is not. It seems that this bacon brother is quite difficult. I found it."

When Song Wen finished speaking, he raised his head, but he saw Lu Siyu holding his head with one hand, his eyebrows closed, his pointed chin drooping, and he was already sitting there asleep.Song Wen was afraid of quarreling him, so he got up and looked at the information on the table. Those records were almost ready, and he marked them carefully.

Song Wenxin said, this person is really true. It was him who wanted to work but did not want to go to sleep, and it was him who was sitting at the table and fell asleep.

Standing across from the table, Song Wen just stared at Lu Siyu's sleeping face from a close distance. His complexion was white, and his eyebrows were as delicate as ice.Seeing that Lu Siyu didn't mean to wake up at all, Song Wen simply walked over, turned his swivel chair, and swept him in his arms. Song Wen used his arms to hug him directly.

Lu Siyu was half asleep and half awake, and suddenly his body lightened. He knew that he was being held by Song Wen and he could smell the person's body, but his eyelids were so heavy that he couldn't lift him, and he made a low voice. The sound was like a cat shouting, and Song Wen hugged him and put him on the bed in the bedroom.Song Wen was afraid that he would wake up, looked at Lu Siyu Qingjun's face, his eyebrows were still closed, and then he put his head down carefully, and then covered him with a quilt.

Song Wen lowered his head to look at Lu Siyu's sleeping face. He thought in his heart, if it could be like this forever, it would seem good.

The next morning, the morning meeting was held by all departments as usual. The small meeting room was occupied by Xu Changying's team. They could only meet temporarily in the forensic medical room. Because it was too late last night, the identity of the body was not confirmed. Lin Xiuran didn't transport the body to the funeral home, but parked it in the forensic room.

Song Wen rubbed his nose as soon as he entered the door of the forensic room. The corpse was left here overnight, and the air smelled of sea salt.

After a short while, the crowd arrived.

The physical evidence was out of work today, and I kept the photos and various materials. Several criminal policemen and Lin Xiuran sat beside the corpse that had long been turned into a corpse, and had a serious meeting.

Song Wen is straightforward: "Last night, Lu Siyu and I have checked the latest missing persons records. In the missing persons files, there is no one that matches the age and height of the deceased."

Lin Xiuran said: "My autopsy here has also been completed. The deceased man was between 25 and 26 years old, and his height was about 180. The DNA and fingerprints of the deceased were not recorded in the relevant database, which means that the deceased may not have a criminal record before his death. In addition, the time of death was about six months ago. The cause of death was a knife in the chest. This knife stabbed the lungs and should die soon. In addition, we found yesterday that there was a scar on the deceased’s abdomen. It was discovered that it was a surgical scar. The deceased did not have a gallbladder. He may have had a cholecystectomy. He had cancer in his body, which means that this is a young patient with advanced cancer."

"The cancer is in the late stage? This person does not have a few days to live?" Fu Linjiang frowned when he heard this. Such a dead person is rare in previous cases. "What kind of hatred is there to kill a terminally ill person? After waiting for a few months, maybe he himself died of illness. Why did he end his life in this way?"

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

Song Wen also couldn't figure it out: "This person is not a missing person, and he has not been recorded. It is strange that he has been dead for so long without reporting the crime."

No family, no friends, no police record, no information, this man is alone, as if abandoned by the whole world.No, he is still connected to the world, that is the murderer who dumped him in that old chemical factory...

Zhu Xiao looked at the corpse lying aside with some sympathy, and thought of a possibility: "Is it possible that this person has been living in a foreign country before, and his relatives think he has not returned from a business trip?"

Lao Jia shook his head: "It's all in the terminal stage of cancer, what's wrong... How can such a critically ill patient come out and run around."

Zhu Xiao continued to infer: "Then if his relatives regard him as a burden, does he have any desire to see where? He wants to see someone... He came to Nancheng alone for medical treatment, or... Regional crimes or trans-regional corpses?"

Fu Linjiang answered: "It's possible. But in this case, you have to apply for a coordinated investigation from various places, and things will become a lot more troublesome..."

"The murderer put the body there, indicating that he has the means of transportation and is very familiar with the local area. Cross-regional transportation, for the murderer, the risk is increased... It is best to consider this possibility after all factors have been completely eliminated. "After Song Wen finished speaking, he turned his head to see Lu Siyu holding a pen in his hand, staring blankly at the corpse in front of him, in a daze.

"Lu Siyu?" Song Wen called him, "What do you think?"

Lu Siyu let out a hum, it seemed like he was awake, he was absent.Yesterday he fell asleep very early, but he woke up less than five o'clock, and his stomach hurts until dawn. Now the pain in his stomach is so severe that it makes it difficult for him to concentrate.It seems that since the last time his stomach bleeds, his stomach attacks have become more frequent than before. No matter how careful he is, it is useless. Now the painkillers have been taken away, and the effects of those other drugs are minimal.

Feeling Song Wen’s gaze cast over, he didn’t want Song Wen to worry. He reached under the table, leaned forward slightly, and put his entire hand under the table against his abdomen. He took a breath and thought logically: "Can you? Start with the condition?" He wanted to say a few more words, but with a twitch in his stomach, he hurriedly gritted his teeth and pressed a low groan into his throat, lowering his head in the hope that Song Wen would not discover his abnormality.

"This is a way of thinking." Lin Xiuran knows and agrees: "In this city, there are still a small number of cancer patients. We can check all patients with related diseases in the city. Male, 25 years old, who has undergone cholecystectomy in the past few years. , There may be records."

Song Wendao: "Let's investigate first. Recently, the large database on the technical investigation side is almost built?"

Speaking of the big database, Zhu Xiao, who was interfacing with technical investigation, immediately showed an expression of disgust.

With the rapid development of the Internet today, the police’s large database has been built for a long time. Nancheng has taken the lead in these aspects. The entire database is extremely large and has a lot of input work. In a city with a population of several million, it needs to be done. Birth information, household registration information, death information, medical treatment, real estate, mobile phone, bank card, license plate number, and various ticket information are all related, which is almost a difficult task to complete.

One of the biggest difficulties is that there are many input errors, and the speed of information generation is much higher than the speed of importing, so that the content of the large police database is much behind.

However, dislike is regarded as dislike. This kind of record of surgery a year ago should be able to be sorted out.Zhu Xiao took the laptop and used his password to enter the Nancheng police database. After entering a few key information, a symbol next to it began to turn, indicating that the screening was in progress.

Everyone held their breath and waited for a full ten seconds. The screen flickered. Song Wen thought it had come out, but saw a progress bar pulled out on the right. The number on it jumped from 0% to 1%...

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

Fu Linjiang smiled bitterly.

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

Song Wen calculated it, if it was calculated initially, it would take a few minutes, and said, "Everyone, take a break."
