Criminal Investigation Notes

After passing several suspects, Song Wen and Lu Siyu left the private room.Song Wendao: "Some of these people should be lying. This atmosphere really doesn't look like a dead teacher."

Lu Siyu nodded next to him: "I think suicide can be ruled out."

If this is really a normal teacher-student reunion, Zhang Dongmei has no reason to commit suicide in the hotel.

Whether it was everyone who didn't take pictures, or everyone answered carefully, it felt a little weird to him, but they still have no way of knowing which ones are lies and what happened tonight.

Those few people seem to have something on their minds, and there is something hidden in their words.

And I don't know if it was his illusion. Lu Siyu felt that the relationship between these people was not so good, and the tone of each other's actions was somewhat distanced.But if their relationship is not good, why should they come to have this meal together?

Lu Siyu lowered his head to meditate. He also went to junior high school. It was three years, more than a thousand days, and something happened every day...Even if he has grown up now, some things are still in his memory. .

Junior high school is a special three years. Compared with elementary school students, they have grown up, but compared to high school, junior high school students are still children.They stand on the edge of children and teenagers, avoiding the wings of their parents.They began to develop in puberty, menarche, voice change, and gradually mature sexually, ignorantly, and began to face the society and the world independently.

Teachers, undoubtedly the people who took them, played an important role during this time.

Three years of experience will imprint an indelible mark on a person's life.

The open classroom door, the wind blowing in from the window, the bells that ring regularly every day, the noisy playground, the textbooks, the endless exams, the endless homework, the snacks from the small shop, hidden in The mobile phones under the desks, the small notes passed to each other, the extracurricular books, and the long way out of school.

Now I can hear the sound of reciting the text and the music of eye exercises when I close my eyes.

The teachers and students who lived together in the same classroom for three years and ten years ago can speak clearly without just a few words.

A meal after ten years, many memories, many emotions, such an understatement, this itself is abnormal.

What are those people suppressing and hiding...

Lu Siyu could feel that there seemed to be a calm lake in front of them, but there were dark waves below.

After thinking for a while, Song Wen asked Zhang Ziqi to call the store manager just now: "Just now, was there something unusual when eating in this private room?"

The shop manager said: "Shao Qian is a frequent customer in our shop. He often brings friends over for dinner. This table is also set by him. The dining standard has been set a long time ago. They brought the cakes by themselves, and the dishes were soon finished. Qian Shao told us that their classmates hadn’t seen each other for a long time, and they didn’t want to be disturbed by us when they were eating and chatting, so they locked the door from the inside. It was probably locked for more than half an hour and then opened again and let us have tea."

More than half an hour is enough to do many things.

When Song Wen heard this, he had some inferences in his heart: "Did there been any abnormal movement in the half hour?"

The store manager shook his head: "The sound insulation of our package is very good. Once the door is locked, you can't hear what is said inside. Anyway, no one went out for more than half an hour."

"Then you go in afterwards? Did you notice any difference?"

The manager and the waiter in the private room shook their heads.

The waiter thought for a while and said, "It seems that I have finished eating and divided the cakes. At that time, the meal is over. Someone goes out to the bathroom or something. The two girls went with the teacher. The teacher seemed quite excited. , Drank a lot of alcohol. Qian Shao went to the bathroom, and came out saying that the phone was lost. After looking for the phone for a long time, I couldn’t find the phone. Then we wanted to pay the bill, so he asked us to take the card reader and swipe the credit card. When I came down, I heard that someone had fallen. It was messy, and we didn't pay attention to who was on the rooftop at the time. We just watched these people running down one after another."

It seems that Qian Shao didn't lie about what Qian Shao said just now. His mobile phone was indeed lost.

Song Wen and the store manager were chatting here, while Lu Siyu went to look at the environment in the corridor. The restaurant was decorated in a so-called new antique style, with anti-slip imitation white marble floor tiles laid on the ground and extensive use on the walls. With glass, wood, and various dried flowers, the whole style is modern and retro.

When you come out of the private room, walk a few steps forward and you will find the rooftop. The door leading to the rooftop is a small door with a lock. It will probably be locked when you are off work, and it will be open during the day.

Lu Siyu walked to the corner of the private room near the small door on the rooftop, and suddenly found something. He pointed to an inconspicuous camera on the wall and asked the store manager: "There is a camera there, can you take a picture of someone on the rooftop? ?"

The store manager looked at it and said, "This camera is taking pictures of the back door. Our management office and financial room are actually on the fifth floor. We only installed this camera because we were afraid of someone entering. From this perspective, there is no No one enters or exits the rooftop."

Lu Siyu lowered his head thoughtfully, and Song Wen said, "Can you show us these camera materials when you look back?" Although this camera can't see the direction of the rooftop, it may also be able to see something else.

The shop owner said: "Then let's export it. If you have any requests, we will definitely cooperate."

Song Wen pointed to a private room next to it: "Thank you to get it out. Now the road is blocked. Let's ask them in this room."

Even if the case cannot be solved completely, it is good to be able to eliminate some suspicions.

The manager nodded and agreed, got up to prepare.

Lu Siyu and Song Wen walked a few steps to the rooftop, where the air was suddenly much cleaner than inside.

This is a two-hundred-square-meter rooftop with some simple tables and chairs. The night breeze is slightly cool, blowing gently. Not long ago, Zhang Dongmei fell from here.

At this time, looking outside from the rooftop, the sky was completely dark, and various signs were lit up, illuminating the entire city.Various patriotic slogans are projected on several hundred-story buildings not far away.

There are joyous crowds everywhere on the street.Everyone is waiting for the fireworks show soon.

The guardrail on the roof is carved in Chinese style, like curved petals, about one meter in the lower part and about one meter in the taller place.It is an essential oil that has been brushed and maintained on old wood, with some wood smell.Lu Siyu walked over and shook. It may have been a while, and the guardrail was a little unstable.

Then Lu Siyu compared it again. If Zhang Dongmei was standing at the shortest part of the guardrail at the time, and the murderer was standing opposite, if he was not prepared, the murderer could push the drunk her down without much effort.Among the few people, the thinnest is the little teacher Tan Shan. Even if she is an adult, it is feasible to use some strength.

Lu Siyu held on to the guardrail, looked down at the flow of people on the street, and compared the location of the blood stains.Then he squatted down again and looked at the nearby guardrail carefully. There were no scratches, the wooden railings were hard to leave fingerprints, and there were no traces on the floor covered with floor tiles.Neither footprints nor scratches were left.

Song Wen took Zhang Dongmei's bag and looked through it inside and out. They were all commonly used items such as keys, tissues and loose powder. Zhang Dongmei's mobile phone was still there, and it had a password that could not be deciphered.

Song Wen looked down at the guardrail for a moment, and asked Lu Siyu: "What model do you think Qianjiang's mobile phone should be?"

Lu Siyu thought for a moment: "Apple's new phone just came out with his earphones. He doesn't cost money and should be the best match." Qian Jiang just pointed to his earphones, which were just released this month. The new model should be bought together as a package, and it is limited globally. Only he can get it first.

Song Wen nodded and said, "I think so."

Lu Siyu looked at Song Wen and asked, "Are you going to look for Qianjiang's cell phone?"

Song Wen said, "It's a pleasure to help others. The dead horse acts as a live horse doctor. Maybe there is some information on the phone." After speaking, he took out his phone and called Captain Zhao of the anti-picking brigade in the city bureau.

Not long after, Song Wen hung up his cell phone and said to Lu Si: "The situation is that the feedback has gone up, but it is estimated that the hope is slim. Zhao Tou said that they lost more than 300 mobile phones during the fireworks show last time. This is still a lot of people When I was too lazy to report to the police and did not provide information, the Bureau of Gu ordered them not to exceed the number lost last time. This year, more than 50 copies have been lost."

Lu Siyu bowed his head and said: "There are still 250 places..."

Song Wen said again: "Guess how many of those 300 were finally recovered last year?"

Lu Siyu guessed blindly: "30?"

Song Wen shook his head: "18. So Zhao Tou said let us look for other clues and don't report too much hope." Based on last year's ratio, there is little hope of recovery. Song Wen sighed and rushed to the Siyu booth. Open his hands, "It seems that this horse is really dead, I am not alive anymore."

The two were talking, and Zhang Ziqi came up from downstairs again: "Team Song, the team downstairs is here, talking to the store manager." Cheng Mo finally rushed over.

Song Wen frowned. Although Gu Ju was talking about cross-group operations and everything was under his command, Cheng Mo was the captain of the third team after all. He suddenly appeared at this moment, making him the newly appointed detachment leader a little embarrassed.

Then came the more difficult things. Zhang Ziqi went on to say: "Team Cheng said... his son's junior high school head teacher was locked in..."

Captain Cheng belongs to the group of people who responded to the national call to give birth and childbirth. He was once divorced. Now there are two children in the family. The eldest daughter has gone to college at the age of 20. The second child is a son, who is 13 years old this year. In junior high school, I went to a middle school in the city.So it sounds, his son’s head teacher may be Tan Shan...

The case hasn't been sorted out yet, and anyone looking for a relationship will come to the door.Song Wen also understood why Cheng Mo had to come, either Tan Shan gave him some news before, or he heard some news.

Song Wen said to Lu Si: "You wait for me down here, I'll go downstairs and say a few words to him, and you have to come up later, don't toss me up and downstairs."

There are five floors in Mingyue Building. There is no elevator, and they are all antique wooden stairs. After a while, the shop assistants followed up and down several times. I don’t know how many times I have to go for business. It seems that working here is also a personal effort. .

Lu Siyu nodded, not ready to follow, and whispered to him: "What are you going to do with Cheng Mo?"

Song Wendao: "Soldiers will come to block, water will come to cover, and the big deal will be interrogated together. In short, we will never let anyone go before we know it."

When Song Wen and the little policeman went downstairs, Lu Siyu stood alone on the rooftop. He thought for a while and felt that Song Wen’s idea of ​​starting with a mobile phone was correct, so he took out his mobile phone and called Boss Cao. phone.

The phone is lost, it may be difficult to find from the police side.Since this is nowhere, try other methods.

Tonight, how many thieves there are on this street should have exchanges with each other and draw the site in advance.Boss Cao is known as the thief of this South City, and maybe there will be clues at this time.

Boss Cao answered the phone, listened to the situation, and after knowing the exact time and location of the lost mobile phone, he refused in every possible way: "Oh, I have already washed my hands. And ah, now this business is for other people's business... A generation has passed on my side...Little brother, don't you give me a problem..."

Lu Siyu said coldly: "Boss Cao said if I can get it."

Boss Cao said: "Okay, okay, I'll try it here. Don't pursue the children below you when you look back. You will pay 10,000 yuan in one hand and deliver the goods in one hand. If you say in advance, this money is not for me. , I have to buy it from over there. In fact, even if the new model is sold, it is more than this price."

Lu Siyu checked the time, and now it was 7 o'clock in the evening, he said again: "The whole machine must be intact, and the information in it must be indispensable. Before eight o'clock, after eight o'clock, I don't want it."

Boss Cao had a headache, but he still said, "I know, I know, I'll work hard. If I don't contact you after eight o'clock, it means I haven't got the things."

After the call here, Lu Siyu strolled around on the rooftop. In another corner of the rooftop, he found a small cigarette butt dropped on the ground.Lu Siyu crouched down, took a bag of evidence from his pocket, and put the cigarette butt in it.

After walking outside the private room, Song Wen had already come up with Cheng Mo. Cheng Mo is in his forties and is also the old captain of the Municipal Bureau. He walked and said: "Really, Teacher Tan, don’t look at his young age, but He is a good teacher who is very responsible for being a teacher. Such a person is absolutely impossible to kill. Besides, it is her teacher and her colleague who are dead. Teacher Cheng is so thin and the deceased is fat, this matter I can't tell..."

Song Wen was aside, rolling his eyes a bit.The truth is correct, but in front of him, he wanted to bend the law for personal gain. Didn't he look at him as the detachment leader?

Lu Siyu greeted him, his handsome face was expressionless, and he did not call Team Cheng. He completely treated Cheng Mo as the air, and asked Song Wen directly: "Team Song, now, are you starting to inquire one by one?"

Song Wendao: "Ask them one by one. Since Team Cheng is also here, let's start with Teacher Tan."
