Although the phone/phone card of the mobile phone is still inside, it has long been shut down and cannot be used, and the mobile phone/phone is quite intact. There is Xie Jibai's father's name in the phone/phone book, Xie Jibai called out the arc number, and sure enough, it was his father's previous phone/phone number, and he still remembered.

However, there is no dialing record in the phone/machine, and it is clean.

It seems that with such a mobile phone/machine alone, nothing can be explained. However, this mobile phone told them that Xie Jibai's father and this person named Peng Xuebai did know each other.

Xie Jibai took the phone/machine and began to be in a daze, he had a lot of questions in his mind. The notebook in his father's hand is Peng Xuebai's, and this notebook seems to be very important, can it show that Peng Xuebai knows something insider/behind?

An empty notebook, what is its importance?

What does Peng Xuebai know?

Peng Xuebai abruptly left City C many years ago, then his whereabouts are unknown, and he died suddenly a few years later, although he died of sudden death from heart/disease, but the cause of sudden death is unknown. Whether his death was just an accident is hard to verify.

Tang Xin patted Xie Jibai on the shoulder and said, "Xiaobai, why don't we go find the old man in the library again." Now only he knows the most. ”

Indeed, the old man knew Peng Xuebai, and they both worked in that library.

However, it was too late, the library was already closed, and they were going to go again tomorrow.

The next day was Saturday, so they didn't have to go to work, and they had plenty of time to run to the library.

Xie Jibai was preoccupied, and he didn't have much dinner at night, so he went to sleep after taking a shower very tiredly.

Tang Xin knew that he was tired, so he didn't bother him, kissed Xie Jibai's forehead, and said, "Xiaobai, don't worry, good night." ”

"Good night." Xie Jibai didn't open his eyes and said softly.

Early the next morning, Xie Jibai and Tang Xin set off from home to go to the library. Although the library may not open so early, they can wait outside for a while.

So after Chen Wanting got up, he found that there was no one next door, and he thought that he would not go on a date again, right? The rhythm of this date is tight enough.

At this time, Tang Xin had already taken Xie Jibai and was about to arrive at the door of the library.

After turning a corner, Tang Xin saw many people in front of him and said, "Xiaobai, what do you see in front?" ”

Xie Jibai looked up, and felt a little bad in his heart. There are a lot of people in front of the library, and they don't come to the library early in the morning to wait in line.

If you take a closer look, not only are there many people, but there are also cars parked in front of the library, those cars are a little familiar, they are all from the police detective bureau.

"Is it the car?" Tang Xin raised his eyebrows and asked.

Xie Jibai nodded and said, "Let's stop too." ”

Tang Xin also drove the car over, and now he didn't need to find a parking space, and drove directly to the side of the team's car.

The two of them got out of the car and saw Bi Chengyuan standing at the door of the library talking to the library staff.

The detectives in Group B were a little surprised to see the deputy captain of Group C and Forensic Doctor Tang suddenly appear, everyone knew each other, so they didn't stop them outside, thinking that they were here to support.

As soon as Bi Chengyuan turned around after speaking, he also saw Xie Jibai and Tang Xin, and said in surprise: "Chen Wanting asked you to come?" ”

Xie Jibai shook his head and said, "No, I'm here to do some personal business." What's going on inside? ”

"One man died." Bi Chengyuan said that when I received the news half an hour ago, I brought someone over to check the situation.

A person suddenly died in the library, Xie Jibai was shocked when he heard it, and asked, "Who is it?" ”

Bi Chengyuan said: "His name is Chang Kunbing, and he is an old employee in the library." ”

When Tang Xin heard this, he instantly remembered that they had seen the old man in the library yesterday, and he had a small sign pinned to his chest with his name written on it. Although he only glanced at it, Tang Xin remembered that it was written with the words "Chang Kunbing".

What a coincidence.

Xie Jibai also frowned immediately, and his heart was cold.

Tang Xin said: "We want to go in and have a look. ”

Bi Chengyuan asked: "Is it someone you know?" ”

Tang Xin said: "Sort of, it has something to do with Xiaobai's notebook." ”

Bi Chengyuan knew about the notebook, and was taken aback when he heard Tang Xin's words, and said, "Come with me." ”

The three of them walked into the library, and there were many police detectives inside, most of them from Group B, who were busy collecting evidence and taking pictures.

The forensic/medical examiner from Group B also arrived and was conducting a simple examination/examination of the scene and the body.

The body was in the staff office at the back of the library, which was closed to the public, and only employees were allowed to enter.

The first person to find out that Chang Kunbing was dead was the library's cleaning aunt, who was in her forties and had worked in the library for three years. She goes to the library early every Tuesday to Saturday to clean up and doesn't come back on Mondays and Sundays.

Today happened to be Saturday, so the cleaning aunt came very early, and arrived at the library at about half past six, and she couldn't remember the exact time.

She went to the library, took the key and opened the door, which was locked. She went in and lowered the door again, and it wasn't until nine o'clock that the library officially opened.

According to the order of work every day, the cleaning aunt first cleaned the trash can, and then began to sweep and mop the floor. She usually has to clean the staff office first, because the library staff will come early.

When she arrives at the door of the employee's office, she finds it locked, which makes her a little surprised.

There are no valuables in the employee's office, not even a computer, just a place to rest, so it is generally not locked, and the door is opened every day.

The cleaning aunt was a little strange, thinking that maybe the new employee didn't know the situation, so she locked the door when she left.

In order to open the door, the cleaning aunt also ran to the communication room of the library to find the key, ran around, got the key, and the cleaning aunt opened the door.

As soon as the door of the employee's office opened, the cleaning aunt saw a shadow in the air, she didn't look up at the time, it seemed that she was subconsciously looking at where the ground was not very clean, so the shadow in the middle of the air, she thought it was a curtain, or a wall hanging.

As soon as she looked up, she was completely frightened, almost out of her body. It wasn't curtains and wall hangings, it was a person. A man's neck was tied and hung from a chandelier on the roof.

After the cleaning aunt reacted, she was so frightened that she shouted for help, ran out of the employee's office, and went to find someone for help.

When the people in the communication room heard the voice, they hurriedly ran over, and they also saw Chang Kunbing who had hanged himself.

The old man looked like he was dead a long time ago, his whole body/body was hanging in the air, his face was painful, and his body/body seemed to have stiffened, without a little temperature.

Everyone was scared enough and quickly called the police.

The case was reported to Team Bi, and Team Bi rushed over with someone after receiving the call.

What Bi Chengyuan didn't expect was that he also met Xie Jibai and Tang Xin here.

Bi Chengyuan took them to the staff office, because this library is very old and has not been renovated at all, the front looks fine, the back is indeed a little tattered, and the staff office is even worse.

The room is very small, only about ten square meters, with a few tables and a few chairs. There are several drinking glasses on the table, and it looks like people use them a lot. In addition, there are some brochures on the table, which are the library's brochures. Other than that, there is not even a computer.

Chang Kunbing's body has been dismantled and temporarily placed on the floor of this room. The forensic/medical examiner in Group B is doing the initial examination/examination.

Tang Xin walked over and said, "Yang Fa/Yi, don't you mind if I come to do a favor?" ”

Yang Fa/Doctor was taken aback when he heard Tang Xin's voice, and immediately asked his assistant to hand Tang Xin a pair of gloves and said, "Of course not, I didn't expect to see Tang Fa/Doctor." ”

Tang Xin didn't say much, reached out and took the gloves, and then didn't put them on in a hurry, but took off the ring on his left hand, turned around and handed it to Xie Jibai, and said, "Xiaobai, help me get it first." ”

Tang Xin took off the ring so as not to get dirty, so he put on his gloves and squatted down to start the autopsy.

Yang Fa/Doctor next to him was already shocked/shocked when he saw Tang Xin suddenly wearing a wedding ring, and when he saw Xie Jibai also wearing a similar style on his hand, his jaw was even more shocked/shocked.

Bi Chengyuan coughed and asked, "How is the situation?" ”

Doctor Yang hurriedly came back to his senses and said: "The preliminary examination/inspection should be suffocation/suffocation, and the specific situation is still uncertain." ”

Tang Xin took a closer look at the corpse, and when he finished reading, there were only a few people left in the room, and Xie Jibai and Bi Chengyuan had gone outside.

Tang Xin took off his gloves and went outside to find Xie Jibai.

Xie Jibai and Bi Chengyuan were asking about the cleaning aunt who was the first to find the body. Tang Xin walked over and stood beside Xie Jibai.

The cleaning aunt said, "When I came in, there should be no one in the library, only the people on duty in the communication room outside. When I saw the body, I was stunned and didn't pay attention to what time it was. ”

Aunt Cleaning is much calmer at this time, when Bi Chengyuan asked just now, she almost couldn't say a complete sentence, and she was stupid at first glance.

Aunt Cleaning said again: "Lao Chang is a very kind person, he smiles all day long, I really didn't expect him to hang himself/kill himself, this is really unthinkable." ”

A little girl next to her also said, "Yes, this is incredible." Chang Lao is a very good person, and he is especially patient with newcomers. The day before yesterday, Chang Lao was still talking to me about the problem of propaganda/biography, let me take the finished product to him today to see if it is okay. How could he suddenly kill himself? ”
