Criminal Investigation Notes

At nine o'clock in the evening, the street lights gradually turned on, and a bright moon hung in the air of the city.

After a busy day, Lu Jun returned to the rental house he was renting. He didn't buy a house after working, but was renting. His parents had already emigrated abroad, and only he and his younger brother were at home.

After this case started, Lu Junchi often worked overtime and came home very late. Today was considered relatively early.

Before going upstairs, Lu Junchi glanced sideways. The light sign advertisement downstairs was contracted by a public welfare organization. It was not a star or a movie poster, but an enlarged photo of a girl. The girl's eyebrows were slightly curved, and she smiled very happily. A few words were written next to it - "Looking for Pei Weiwei".

Today, the girl has been missing for nearly 100 days. Although they have been searched in many ways, no trace of Pei Weiwei has been found.

Lu Junchi still remembered, because he handled this case.

Three months ago, his serious crime team received three related cases, including information about Pei Weiwei. The police suspected that Pei Weiwei was also killed by Song Rongjiang.

At that time, Lu Junchi led the team and quickly caught the murderer. The murderer admitted the criminal facts of the other two cases, but denied Pei Weiwei's case.

After the suspect was caught, the case was quickly transferred out to be investigated by other criminal investigation teams. It was no longer within the scope of the serious crime team, and Lu Junchi could no longer intervene. Since there was no evidence to correct, the police also failed to confirm whether Pei Weiwei's disappearance was the work of the same murderer.

Today, the prisoner at that time has also been tried and is about to be executed, but Pei Weiwei has not yet been found...

Lu Junchi walked upstairs, opened the door, and turned on the light. This is a small one-bedroom house, with only one bedroom and one living room. The kitchen is small, but the whole is clean and everything is in order. in order. On one of the walls, whiteboard paper was pasted, and he used it as a whiteboard.

It is divided into different areas, and different materials of each case are posted. In the lower right corner is the recent mutilated body case, and the upper left corner is about Pei Weiwei.

The case was handed over long ago, but Lu Junchi continued to investigate. In the spare time when there was no case before, he was also visiting everywhere, collecting all kinds of relevant information, hoping to find some clues.

Lu Junchi remembered his last meeting with Bureau Tan.

More than half a month ago, he compiled a document with doubts about the results of the case investigation, and went to the General Administration to hand it over to the Tan Bureau.

At that time, he explained Tan Bureau: "Tan Bureau, although I am not in charge of this case, I still compiled the information. I hope it can help those who are still investigating..."

Tan Bureau took over the thick information: "Lu Team, you have your mind." Then he sighed, "After Song Rongjiang was arrested, the team to find Pei Weiwei has done a lot of search work and invested a lot of manpower and material resources. , but it has always been in the bottleneck. Regarding this case, I am also trying to find a way recently, hoping to make a breakthrough in this matter. "

Bureau Tan put it euphemistically. In fact, the team of criminal police officers who continued to search could not find any trace of the girl. They applied to be classified as missing persons twice, but Bureau Tan did not approve.

But that group of people has long since given up. They tried their best to find more clues and could only wait for time to forget everything.

Lu Junchi said: "I hope to do my part. The search for the missing girl is not over yet for me."

Maybe the case will become a dead end, even take years to find, and as long as the girl isn't found one day, he won't take it out of his file.

Tan Bureau looked at Lu Junchi's resolute gaze, he understood that the accumulated lack of clues would kill everyone's fighting spirit, but there were always people who persisted.

Tan Bureau looked at the thick stack of documents. In the end, Lu Junchi did not rule out Song Rongjiang's suspicion. He even recorded the amount of fuel lost in Song Rongjiang's car every day from before Pei Weiwei disappeared to before his arrest. , and the locations that can be detected by cameras along the road are marked one by one.

Bureau Tan could see that the information was organized in great detail, and many analyses were in place. He felt a little bit: "Captain Lu, I think this information will be very helpful for the follow-up search. For the rest, I will come up with a solution. ."

If the conventional method is completely useless, then he has to do something unconventional.

Lu Jun nodded and got up: "Tan Bureau, if there is nothing else, I will go first."

Tan Bureau suddenly raised his head: "By the way, the army team, I remember you rented a house?"

Lu Jun was stunned for a moment: "Yes, it's near the General Office, but my house is about to expire."

"How long?"

"Less than a month."

Bureau Tan nodded: "Then you go back and clean up first, don't rent a new house, I have some arrangements here, and I will notify you when the arrangements are made."

Lu Junchi didn't know what Bureau Tan's so-called arrangement would be. Now that the day of checking out is approaching, he has to start cleaning up.

In the middle of the case these few days, there is a stalemate, so I have to pack a little more. If I am busy in the next few days, it is estimated that it will be all night long, and it will be too late to pack things.

Since he took over the major crime team two years ago, Lu Junchi has sealed up his private life. He has no leisure, entertainment, no movies, no games, and even apart from having dinner with his colleagues in the team, he pushed all the extras. socialize.

There were several leaders who wanted to introduce their daughters and relatives to him, but Lu Junchi all politely refused.

In addition to eating, sleeping and exercising every day, I just soak in those cases. Others say that the serious crime team has solved many cases, but it really depends on time, perseverance, courage and hard work.

Lu Junchi stretched out his hand and began to pick up the files of the case files from the wall. When he was in the middle, Lu Junchi's hand stopped for a while. A large piece of the wall was about the case of fine sand. But in this case, he found the least relevant information.

It was the case he wanted to find out the most, but it was so far from the truth...

Lu Junchi took down a stack of documents and packed them in a box.

Tired of packing up, he sat on the bay window and picked up the glass bottle on the head of the bed.

Lu Jun turned off the light late, and the bottle in his hand lit up. It was a whole bottle of luminous stars, which he counted over and over again, a total of ninety-nine.

The curtains were not drawn, and the moonlight shone through the gaps in the gauze curtains, and outside was a brightly lit city night scene.

Under the moonlit night, he held the glass bottle in his palm, the glass bottle glowed brightly, and the bottle seemed to be full of fireflies.

Pei Weiwei's case, as well as the mutilated body case... A lot of things were pressing on his chest.

During the day, he is busy and has many things to face and solve. But in this dark night, he was thinking that if that person was by his side, these cases would be solved easily.

The ringing of the phone suddenly interrupted Lu Junchi's thoughts, and he answered the phone.

"Brother... I had an appointment to play basketball with my classmates at night. I just came back from the shower and saw your message. What are you looking for from me?" Lu Haochu's clear and youthful voice came from the phone.

Lu Haochu is a junior this year. He is studying in the Information Technology and Network Security Branch of Huadu Police Officers College, specifically video investigation technology. With the gradual popularization of video surveillance technology, surveillance video has become one of the important evidences, and it is also an important direction for police investigation. This major has only been established for a few years, and the first batch of graduates were snatched away by police stations as soon as they left the school, and the supply was in short supply.

Lu Jun said lately: "I want to ask you about someone. I went to your school two days ago and met a teacher who is a little strange." He was recently considering a consultant for the serious crime team, and he felt that this teacher Su was very suitable.

Lu Junchi was also a little hard to explain. Since that meeting, the thin figure lingered in his mind.

After Lu Junchi came back from the Chinese police that day, he had already reviewed Su Hui's information. The information was simple, ordinary, and quite satisfactory. The standard was like a standard answer, and he could hardly see anything he wanted to know.

Lu Junchi thought about it again and again, but decided to ask his younger brother who was studying at the police in China, maybe he could know more, so in the afternoon, he sent a message to Lu Haochu, but he didn't expect him to call back soon.

"Who?"

"A teacher named Su Hui seems to be teaching criminal sociology."

"Mr. Su? Have you met Mr. Su from our school?" Lu Haochu's voice became excited, "Mr. Su is the most popular teacher in our school. If you want to sign up for his open class, you must grab it , even harder to grab than Taobao's spike!"

Lu Jun didn't expect that Su Hui's evaluation in his brother's mouth was completely different from that in Director Liao's mouth, and they were two extremes: "Is this teacher Su famous in your school?"

Lu Haochu continued to be excited: "It's not only famous, the female students who want to chase Mr. Su can line up from the east gate of the school to the west gate of the school!"

Lu Junchi asked, "Why? Is it because he looks handsome?"

"Our Chinese police girls don't judge people by their appearance, mainly because Mr. Su's class is good." Speaking of which, Lu Haochu explained, "Mr. Su's class is not only interesting, but also different from other teachers. The cases mentioned are very exciting, and the analysis is in place..."

Lu Jun hesitated for a while, but still asked what he heard from Director Liao: "But I heard someone say that he is not serious in class? Is his academic performance average?"

"Hey, brother, where did you hear the rumor?! Did the old pedant of the crime academy say it? I already knew that they didn't like Teacher Su, because Teacher Su's students gave them a few streets! Really, When Mr. Su lectures, he is always serious and serious. The more he listens to his analysis, the more fascinated people become. After listening to his lectures, people's perception of the evil of human nature will change from the bottom of their hearts. ."

"This teacher Su, seems to be in poor health?" Lu Junchi asked again.

"Yeah... Mr. Su's eyesight is not very good, he can't hear in one ear, and his voice is hoarse. He needs a microphone to teach, and he often coughs, so he can't be tired... For this reason, our student union has set up a special help group to help Mr. Su picked up the courier, cleaned up, etc..." Lu Hao was very angry when he mentioned this, "But I've only been in line twice!"

"…"

Lu Junchi was a little speechless. He was too familiar with Lu Haochu. His younger brother was spoiled by his parents, and he was the only one who could not help him when the oil bottle was overturned.

Just such a person, still rushing to clean up for others?

"Are you rushing in line to serve people?"

"No, no, no! Brother, you don't understand, anyway, he is very popular with our students..." Lu Haochu said coquettishly, "Oh, brother, if you can add it to Teacher Su's WeChat, can you give me a message? , you say, I am a third-year student of the Chinese police, and I have taken his open class. If you have any questions, I want to ask him, can you add it, or you can ask him to make a book list for me..."

Lu Junchi now fully understood that his younger brother was that teacher Su's fanboy, and he looked like a die-hard fan.

The two were talking about this when Lu Junchi's cell phone suddenly rang again. He said to Lu Haochu, "Wait a minute, I have something to do here. I'll hang up first, and I'll talk to you later."

He cut off the phone, and Xing Jing's voice came from the opposite side: "Captain Lu, the results of the micro-evidence test you applied for have come out. We found trace amounts of black physical evidence in the fingers of the three hands..."

"What is it?" Lu Junchi asked hurriedly.

"It's a trace of coffee powder."

coffee powder? Lu Junchi frowned slightly, it seemed that there was a connection between the victims.

Xing Jing said: "In addition, we also found some strange things. Captain Lu should also know that we followed the investigation here. We found the suspected murderer in the three cars near where the stump was found. The traces left, these traces include fingerprints and some other samples, but ... from our current results, these traces belong to different people."

"…"

Lu Junchi frowned slightly.

different people?

Are there multiple suspects in this case? Are these stumps linked to a criminal syndicate?

Or did they swipe in the owner's information by mistake?

But it shouldn't, the information left on these three cars has a certain peculiarity...

Lu Junchi's expression became serious: "I'll make work arrangements right away."
