last case

Although the calling card of the mobile phone is still inside, it has been shut down for a long time and cannot be used, but the mobile phone is still in good condition.There was Xie Jibai's father's name in the phone book, Xie Jibai dialed out the arc number, it was indeed his father's previous phone number, he still remembered it.

However, there is no call record in the mobile phone, and it has been cleaned up.

It seems that such a mobile phone alone can't explain any problems.However, this mobile phone told them that Xie Jibai's father and this person named Peng Xuebo did indeed know each other.

Xie Jibai held the mobile phone in a daze, he had many questions in his mind.The notebook in father's hand belonged to Peng Xuebai, and this notebook seemed very important. Could it explain what Peng Xuebai knew?

What is the importance of an empty notebook?

What did Peng Xuebo know?

Peng Xuebo suddenly left City C many years ago, and his whereabouts are unknown. A few years later, he died suddenly. Although he died of a heart attack, the cause of the sudden death is unknown.Whether his death was just an accident is really difficult to verify.

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

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

However, it was too late, the library was closed long ago, and they had to go tomorrow if they wanted to go.

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

Xie Jibai was so preoccupied that he didn't have a good dinner at night, so he went to sleep after taking a shower very tired.

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

"Good night." Xie Ji Bai said softly without opening his eyes.

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

So after Chen Wanting got up, he found that there was no one next door, thinking 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 brought Xie Jibai with him, and he was about to arrive at the entrance of the library.

Turning a corner, Tang Xin saw many people in front of him and said, "Xiaobai, what's going on in front of you?"

Xie Jibai looked up, his heart skipped a beat, he felt something was wrong.There are quite a few people in front of the library, so early in the morning, it is not necessary to come to the library and wait in line.

Taking a closer look, there were not only a lot of people, but also cars parked in front of the library. Those cars looked familiar, and they all belonged to the police department.

"Is it Team Bi's car?" Tang Xin raised his eyebrows and asked.

Xie Jibai nodded and said, "We'll stop there too."

Tang Xin also drove the car, and now he didn't need to look for a parking space, and drove directly to the side of Team Bi's car.

The two got out of the car, and at a glance, they saw Bi Chengyuan standing at the door of the library talking to the library staff.

The police detectives in group B were a little surprised when they saw the deputy captain of group C and forensic doctor Tang appear suddenly. Everyone knew each other, so they didn't stop them outside, thinking they were here for support.

After Bi Chengyuan finished speaking, he turned his head and 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 for some personal business. What happened inside?"

"One person died." Bi Chengyuan said, I brought someone over to check the situation after receiving the news half an hour ago.

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

Bi Chengyuan said: "It's called Chang Kunbing, and he's an old employee in the library."

When Tang Xin heard it, he immediately remembered that they saw the old man in the library yesterday, and he had a small sign with his name written on it on his chest.Although he only glanced at it, Tang Xin remembered that it said "Chang Kunbing".

What a coincidence.

Xie Ji Bai also frowned immediately, feeling a chill in his heart.

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

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

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

Knowing about the notebook, Bi Chengyuan was surprised when he heard Tang Xin's words, and said, "Come with me."

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

The forensic doctor of group B also arrived and was simply checking the scene and the corpse.

The body is in the staff office behind the library, which is closed to the public and only staff can enter.

The first person who discovered Chang Kunbing's death was the cleaning lady of the library. She was in her 40s and had worked in the library for three years.Every Tuesday to Saturday, she goes to the library to clean up very early, and she does not come on Monday and Sunday.

Today happened to be Saturday, so Auntie Cleaning came very early and arrived at the library at about 06:30. She couldn't remember the exact time.

She went to the library, took the key and opened the door, but the door of the library was locked.After she went in, she lowered the door again, and the library would not officially open until nine o'clock.

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

She went to the door of the staff office and found that the office was locked, which made her a little surprised.

There is nothing valuable in the staff office, not even a computer, it is just a place for rest, so it is usually not locked, and the door is opened every day as soon as you push it.

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

In order to open the door, the cleaning aunt ran to the reception room of the library to find the key. After running around and getting the key, the cleaning aunt opened the door.

As soon as the door of the staff office was opened, Auntie Cleaning saw a shadow in midair. She didn't look up at the time, as if she was subconsciously looking at what was not clean on the ground, so she thought the midair shadow was a curtain or a wall hanging. some type of.

As soon as she looked up, she was completely frightened and stupid, almost out of her wits.It was not curtains and wall hangings, but a person.A man was tied by the neck and hung from a chandelier on the roof.

After the cleaning aunt came to her senses, she was so frightened that she shouted for help, ran away from the employee's office, and went to ask for help.

The people in the reception room heard the sound and ran over quickly, and also saw Chang Kunbing who had hanged himself to death.

The old man seemed to have died a long time ago, his whole body was hanging in the air, with a painful expression on his face, his body seemed to be stiff, without any warmth.

Everyone was scared enough to call the police.

This case was reported to Dui Bi, and Dui Bi rushed over with people 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 good, but the back is indeed a bit dilapidated, and the staff office is even worse.

The room is small, only about ten square meters, with a few tables and chairs.There are several water glasses on the table, and it seems that people often use them here.In addition, there are some brochures on the table, which are library brochures.In addition, there is no computer.

Chang Kunbing's body has been untied and temporarily placed on the floor of this room. The forensic doctor of group B is doing the preliminary examination.

Tang Xin walked over and said, "Forensic Doctor Yang, do you mind if I come to help you?"

Forensic Doctor Yang was startled when he heard Tang Xin's voice, and immediately asked his assistant to hand Tang Xin a pair of gloves, saying, "Of course not. I didn't expect to see Forensic Tang."

Tang Xin didn't say much, reached out to take the glove, and didn't put it 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 to avoid getting it dirty, then put on his gloves, squatted down and started the autopsy.

Forensic doctor Yang next to him was already shocked when he saw Tang Xin suddenly wearing a wedding ring, but when he saw that Xie Jibai was also wearing a similar ring, his jaw dropped from shock.

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

Forensic doctor Yang quickly regained his composure and said, "Preliminary examination shows that he died of suffocation. The specific circumstances are still uncertain."

Tang Xin looked at the corpse carefully, and when he finished, there were only a few people left in the room, Xie Jibai and Bi Chengyuan went outside.

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

Xie Jibai and Bi Chengyuan were inquiring about the situation of the cleaning lady who was the first to discover 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 person on duty in the reception room outside. I was shocked when I saw the corpse, and I didn't pay attention to the specific time."

Auntie Cleaning has calmed down a lot now. When Bi Chengyuan was questioning her just now, she could hardly utter a complete sentence.

Aunt Baojie said: "Old Chang is very kind and always smiling all day long. I really didn't expect him to hang himself. It's really unexpected."

A little girl next to me also said: "Yes, this is incredible. Mr. Chang is a very good person, and he is very patient with newcomers. Mr. Chang was still talking to me about the brochure the day before yesterday, and asked me to show him the finished product today. See if it works. How did he kill himself suddenly?"
