Criminal Investigation Files

After passing through several suspects, Song Wen and Lu Siyu walked out of 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 beside 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 restaurant.

Whether it was that no one took a photo, or that everyone answered cautiously, it made him feel a little weird, but which ones were lies and what happened tonight, they have no way of knowing now.

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

And I don't know if it's his illusion, Lu Siyu feels that the relationship between these few people is not so good, and there is a sense of distance between each other's actions and tone.But if their relationship is not good, why come to have this meal together?

Lu Siyu lowered his head and meditated. He also went to junior high school. It was three years, more than 1000 days, and something happened every day... Even now that he has grown up, some things still remain in his memory.

Junior high school is a special three years. Compared with primary school students, they have grown up, but compared with high school students, junior high school students are still children.They stood on the edge of children and teenagers, hiding from the wings of their parents.They begin puberty development, menarche, voice change, and gradually become sexually mature, ignorant, and begin to face the society and the world independently.

Teachers, undoubtedly the ones who lead them, played an important role during this time.

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

The open classroom door, the wind blowing in from the window, the bell ringing regularly every day, the noisy playground, the textbooks, the endless tests, the endless homework, the snacks from the small shop, hidden in the The mobile phone under the desk, the small notes passed to each other, extracurricular books, and the long way to school.

Now I close my eyes and seem to be able to hear the voice of reciting the text, as well as the music of eye exercises.

We live together in the same classroom for three years, and the teachers and students ten years ago can not be explained clearly in a few words.

A meal ten years apart, many memories, many emotions, such an understatement is abnormal in itself.

Those people are suppressing something, hiding something...

Lu Siyu could feel that there seemed to be a calm lake in front of their eyes, but the waves below were surging.

After thinking about it, Song Wen asked Zhang Ziqi to call the store manager over: "Just now, was there anything unusual during the meal in this private room?"

The store manager said: "Qian Shao is a regular customer in our store, and he often brings friends over for dinner. This table was also set by him. The standard of dining has been set long ago. They brought the cakes themselves, and the dishes were served quickly afterward. , 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 he locked the door from the inside. It was locked for more than half an hour, and then opened again, allowing us to serve tea.”

More than half an hour is enough to do a lot of things.

Hearing this, Song Wen made some inferences in his heart: "Did there be any unusual movement inside during that half hour?"

The store manager shook his head: "The sound insulation of our private rooms 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."

"And then you go in? Did you notice any difference?"

Both the store manager and the waiter in the private room shook their heads.

The waiter thought for a while and then said: "It seems that I finished eating and divided the cake. At that time, the meal is over. Someone went to the bathroom or something. Two girls went with the teacher. The teacher seemed quite excited , drank a lot of wine. Qian Shao also went to the bathroom, and when he came out, he said that he had lost his mobile phone. After searching for the mobile phone for a long time, he couldn't find it. When I came down, I heard that someone had fallen. It was a mess at that time, and we didn’t pay attention to who was on the roof at that time. We just watched these people run down one after another.”

It seems that what Qian Shao said just now was not lying, 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 neo-ancient style, with non-slip imitation white marble floor tiles laid on the floor, and a lot of white marble tiles used on the walls. With glass, wood, and various dried flowers, the whole style is both modern and retro.

After leaving the private room, walk a few steps forward and you will find the roof. There is a small door leading to the roof. There is a lock on the door, which is probably locked when you get off work, and it is open during the day.

Lu Siyu walked to the corner of the private room near the small door on the roof, and suddenly found something, pointed to an inconspicuous camera on the wall and asked the store manager: "There is a camera over there, can you take pictures of someone going up to the roof?" ?”

The store manager looked at it and said: "This camera is showing the door on the back side. Our management office and financial office are actually on the fifth floor. We installed this camera because we were afraid that someone would enter. From this angle, we can't see anything at all." No one is going in or out of the rooftop."

Lu Siyu lowered his head thoughtfully, and Song Wen said, "Could you show us the camera data later?" Although the camera couldn't see the direction of the rooftop, it might have captured something else.

The 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: "Please clean up the inside, the road is blocked now, we will ask them in this room."

Even if the case cannot be completely solved, it would be good if some suspicion can be eliminated.

The store manager nodded in agreement and got up to prepare.

Lu Siyu and Song Wen walked a few steps to the rooftop outside, and the air here was much fresher than inside.

This is a [-]-square-meter rooftop with some simple tables and chairs arranged on it. The night breeze is slightly cool and blows gently. Not long ago, Zhang Dongmei fell from here.

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

On the street, there are happy crowds everywhere.Everyone is waiting for the fireworks display in the near future.

The guardrails on the roof are carved in Chinese style, like curved petals. The lower part is about 1.1 meters, and the higher part is 1.4 meters.It was old wood brushed with essential oil for maintenance, and it had some woody smell.Lu Siyu walked over and shook it. It may have been a while, and the guardrail was a little unstable.

Then Lu Siyu made another comparison. If Zhang Dongmei was standing at the lowest point of the guardrail and the murderer was standing opposite, if he was unprepared, the murderer would have pushed her down drunk without much effort.Among the few people, the young teacher Tan Shan was the thinnest. Even she was an adult, so she could use some strength.

Lu Siyu supported the guardrail, looked down at the flow of people on the street, and compared the positions of the bloodstains.Then he squatted down again and carefully looked at the nearby guardrail. There were no scratches, the wooden railings were hard to leave fingerprints, and there were no traces on the tiled floor.It left neither footprints nor scratches.

Song Wen took Zhang Dongmei's bag and went through it inside and out. There were some keys, tissues, loose powder and other commonly used items. Zhang Dongmei's mobile phone was still there, with a password, which could not be deciphered.

Song Wen bowed his head by the guardrail and thought for a moment, then asked Lu Siyu, "What model do you think Qianjiang's mobile phone should be?"

Lu Siyu thought about it for a while: "Apple's new phone just came out, it is matched with his earphones, he is not short of money, it should be the best match." Just now Qian Jiang pointed at his own earphones, which were just released this month The new model should be bought together as a set, and it is limited to the world. Only those like him can get it first.

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

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

Song Wendao: "It's fun to help others. A dead horse is a living horse doctor. Maybe there is some information on the phone." As he spoke, he took out his phone and called Captain Zhao of the anti-pickup brigade in the Municipal Bureau.

Not long after, Song Wen hung up the phone and said to Lu Siyu: "The situation is reported, but it is estimated that there is little hope. Zhao Tou said that they lost more than 300 mobile phones when they received the police during the fireworks show last time. This is still a lot of people. When they were too lazy to report to the police and did not provide information, Bureau Gu ordered them not to exceed the number lost last time. So far this year, more than 50 copies have been lost.”

Lu Siyu lowered his head and said, "There are still 250 places..."

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

Lu Si guessed blindly: "30?"

Song Wen shook his head: "18. So Zhao Tou said let's look for other clues and don't report too much hope." According to last year's rate, the hope of recovering it is very small. Song Wen sighed and rushed to Lu Siyu's booth Opening his hands, "It seems that the horse is really dead, and I am beyond medical treatment."

While the two were talking, Zhang Ziqi came up from downstairs again: "Captain Song, Captain Cheng has arrived downstairs and is talking to the store manager." Cheng Mo finally rushed over.

Song Wen frowned. Although Gu Ju was talking about cross-team assignments and everything was under his command, Cheng Mo was the captain of the third team after all. He suddenly appeared at this time, which made him, the newly appointed team leader, a bit embarrassed.

Then came the more difficult thing, Zhang Ziqi went on to say: "Cheng Dui said... his son's junior high school head teacher was locked inside..."

Captain Cheng belongs to the group of people who responded to the call of the country and gave birth early. He was once divorced and now has two children at home. The eldest daughter is going to college at the age of 20, and the second is a son. He is 13 years old this year and happens to be in junior high school. He studied in No. [-] Middle School in the city.From the looks of it, his son's head teacher might be Tan Shan...

Before the case was cleared up, the people looking for a relationship came to the door.Song Wen also understood why Cheng Mo had to come, either Tan Shan had given him some news before, or he had heard some news.

Song Wen said to Lu Siyu: "You wait here for me to come down. I'll go downstairs and talk to him. I have to come up later. Don't mess with me upstairs and downstairs."

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

Lu Siyu nodded, not planning to follow, and asked him in a low voice, "What are you going to do with Cheng Mo?"

Song Wendao: "Soldiers come to block, water comes to cover up, at worst, let's interrogate together, in short, we will never let people go until we understand it."

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

This phone is lost, it may be difficult to find it from the police side.If this doesn't work, try another method.

Tonight, how many thieves are there on this street, they should communicate with each other, and the site will be drawn up in advance.Boss Cao claims to be the culprit in Nancheng, so he might have a clue at this time.

Boss Cao answered the phone, listened to the situation, and after knowing the exact time and location of the lost phone, he made excuses in every possible way: "Oh, I have already washed my hands in a golden basin. And ah, this business is now someone else's business... It’s been a while since I’ve been here...Little brother, aren’t you giving me a problem..."

Lu Siyu said coldly: "Boss Cao just ask if you can get it."

Boss Cao said: "Okay, okay, I'll try it here, and don't go after the children below. For 1 yuan, pay with one hand and deliver the goods with the other. It's agreed in advance that this money is not for me. , I have to buy it back from there. In fact, even if the new ones are sold off, they will cost more than this."

Lu Siyu looked at the time, it was more than seven o'clock in the evening, and he said again: "The whole machine must be in good condition, and the information inside must not be missing. Before eight o'clock, after eight o'clock, I don't want it."

Boss Cao had a bit of a headache but still said: "I know, I know, I will work hard. If I don't contact you after eight o'clock, it means I didn't get the things."

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

Going outside the private room again, Song Wen and Cheng Mo have come up. Cheng Mo is over 40 years old this year and is also the old captain of the city bureau. A good teacher who is a good example and extremely responsible. It is absolutely impossible for such a person to kill someone. Besides, it was her mentor and her colleague who died. Teacher Cheng was so thin and the deceased was slightly fat. This matter cannot be justified. ..."

Song Wen was on the side, rolling his eyes a little.The truth is correct, but trying to bend the law for personal gain in front of him, does this mean that he, the detachment leader, is not paying attention to him?

Lu Siyu greeted him, his handsome face was expressionless, and he didn't call Cheng Mo, he completely ignored Cheng Mo, and asked Song Wen directly: "Song team, now, should we start asking each of them one by one?"

Song Wendao: "Let's ask them one by one. Since Dui Cheng is here, let's start with Teacher Tan."
