At eight o'clock the next morning, Xie Huai drove them to the task force.

The task force's temporary office is on the third floor of the police station, and the entire floor is occupied by their people.A large-scale criminal case investigation task force must at least have professionals such as criminal police, cyber police, forensic doctors, trace investigators, psychologists, legal consultants, and forensic experts.Functionally, they are subdivided into secretary group, negotiation group, inspection group, intelligence group, monitoring group, action group, and support group. Each organization is orderly and each performs its duties.

Xie Huai greeted the colleagues who came and went, and took the time to introduce Bao Le.The little girl was surprised from ear to ear. This was the first time she realized that there were more people involved in the detection of this case than she had imagined.Every one of them, like Xie Huai, has been working around the clock, working overtime, eating and lodging at the police station since the establishment of the task force, in order to reveal the truth to the deceased as soon as possible and bring the murderer to justice.

Qin Yao noticed Xie Huai when he entered the door, and naturally also noticed the little girl next to him, wearing a peaked cap and a mask.She put her hands on Han Ziyang's shoulders, and smiled like a fox: "That girl is Jiang Baole, right?"

As soon as she finished speaking, Jun Zhi raised his eyes when he heard something, and happened to look in their direction impartially.Those eyes, as cold as snow, looked at Qin Yao neither sad nor happy.With just one glance, he saw the person clearly, and then looked away without much interest. After that, he never took his eyes off Jiang Baole.

Comrade Old Han shook his cousin's hand, and said with a half-smile: "The meeting is about to start, you should go back and sit down first, little brother still has some things to do."

Qin Yao was puzzled: "Where are you going?"

Han Ziyang waved at her with his back, and before Qin Yao entered the meeting room, he saw him walking towards Xie Huai without haste.The relationship between the two brothers has always been very good. Comrade Old Han habitually hooked his shoulders but failed. He snorted dissatisfiedly, and then turned to Bao Le and said, "Miss Jiang, take a step to talk."

...

The meeting room of the task force is a bit like a school classroom, full of more than 20 people.Bao Le entered through the back door, and immediately spotted Jun Zhi sitting in the penultimate row.Qin Yao on the stage was reporting the autopsy results of Luo Xin's case, and the little girl off the stage had slipped to Junzhi's side in one go.As soon as she put down the bench on Junzhi's right, the other party glanced at her, and Bao Le quickly made a silent gesture, just like a student who is late for class and doesn't want to be discovered by the teacher.

"The deceased Luo Xin's throat was cut by the murderer with a sharp weapon. The knife cut the victim's respiratory tract and carotid artery at the same time. Part of the blood ejected from the carotid artery entered the respiratory tract, causing the human body to cough and choke.The blood coagulation reaction makes the blood more viscous. The viscous blood forms foamy blood foam under the action of the airflow, which seriously blocks the respiratory tract and causes him to suffocate to death in a short time."

Qin Yao said: "From the perspective of the cause of death, the murderer is very likely to have professional medical knowledge. It is not an easy task to cut off the trachea and artery at the same time. It is difficult for a layman to do it. If you just cut off the respiratory tract, the amount of bleedingThere will be very little, and it will not affect breathing. In addition, according to the on-site monitoring, the direction of the murderer's knife, and some footprints left in the elevator, the murderer is male, right-handed, about 1.7 meters tall, and has a body shapeWell-proportioned."

Bao Le noticed that after Qin Yao finished speaking, a middle-aged man in his 40s or 50s asked a few more questions about her report.

"The one sitting in the first row must be Director Zhao," the little girl put her thumbs up against Jun Zhi's ear and said, "He's the one from the police station!"

Jun Zhi was thoughtful.

"The next thing I want to talk about is the re-examination of the relevant autopsy results of the '06 Pingsheng Street Car Accident Case' that was incorporated into this serial murder case," Qin Yao flipped the PPT page, "The autopsy results of the yearAs far as the file records are concerned, there is no problem. As far as the autopsy results are concerned, the victim Zhu Yan did die in a car accident and suffered a fractured skull.The test results showed that there was no drug effect."

Bao Le frowned, and said in a low voice: "That's not right, didn't my mother say that the deceased was stabbed in the abdomen back then, why didn't he have any external injuries?"

As if to confirm her words, Qin Yao said again: "The number of people who die in car accidents across the country is more than 100,000 every year. According to my years of forensic experience, craniocerebral injuries are usually caused by people walking at low speed being hit by cars driving at high speed.As a result, the person had a process of flying forward, so the head hit the ground or a hard object. However, according to the autopsy report of the victim Zhu Yan, her head first hit the bumper of the car, and then her body flew up and landed on the ground.The ground, the back of her head hit the concrete floor. Zhu Yan is 1.63 meters tall, and the bumper of the car is less than 1 meter high. She had to bend over to get such a wound."

Han Ziyang followed her words and continued: "I would like to add something about this point. Because the victim Zhu Yan's family is only left with her mother, and her mother has suffered from serious mental illness since her daughter's accident, so she has been living in the hospital.In a nursing home. I went to a nursing home two days ago. Her current condition is so serious that she cannot receive visitors. But I asked the nurse who usually takes care of her. It is said that Zhu’s mother has always felt that her daughter was murdered..”

"So yesterday, I went to the home of Jiang Baole, a witness to the car accident. Her parents mentioned that according to the police officer who came to them to make a statement later, Zhu Yan was stabbed in the abdomen at that time. Due to excessive blood loss, her body lost her balance.He hit his head during the car accident and died at the scene."

"But the autopsy report did not say that she had a knife wound on her abdomen." Qin Yao retorted, "This report was made sixteen years ago, and the teacher who led the autopsy had passed away at that time. Even if it is suspicious, it is as obvious as a knife wound."It is impossible to miss the clues. I think the authenticity of this confession is still doubtful."

"That's right, so I went to check the police officer in charge of the car accident. After all, this police officer told the witnesses about these things." Han Ziyang switched the projection to a photo, "Guan Shuping, fifty-seven years old this year,Sixteen years ago, he was a policeman in the area of Zaoliu Hutong. It is said that he was on business nearby and was one of the first policemen to arrive at the scene. The case was finally handed over to the accident squadron of the traffic police brigade in the jurisdiction, and the case was closed within half a month.One month after the case was closed, Guan Shuping resigned and then left Bei Jing, and we are still looking for his whereabouts. Judging from the current clues, he may not be a suspect, but he must be an insider."

Bao Le showed an expression of admiration: "I really didn't see that Team Leader Han is so powerful before. It's only been a long time since last night, and he has done so many investigations!"

After Han Ziyang finished adding, he made a "please" gesture to Qin Yao: "Qin Fayi, you continue."

Qin Yao nodded: "I don't have anything to add to the first two cases. Let's talk about the case of jumping from a building in Bei Jing Comprehensive Experimental High School in 2006. This is obvious. There was surveillance at the time, and the deceased did jump to his death by himself. But the autopsy report of the year pointed out that the deceasedThere were many old injuries all over the body. The forensic doctor at that time conducted a comparison of the wounds and concluded that they were caused by ball hitting, ballpoint pen puncture or even cigarette butt burns. Therefore, I suspected that it was campus bullying. But after the jumping incident, the school made it clear with 'school rulesOn the grounds that students are not allowed to smoke, they denied that the burns caused by the cigarette butts were caused by the students, thus denying the existence of campus bullying. In addition, the parents of the students also admitted their domestic violence..”

"It's just that even if cigarette butts can explain it, what about ball hitting and ballpoint pen strokes? As far as I know, the student's parent is an alcoholic, and there is no ball at home that can cause his forehead injury. Beijing Comprehensive High School is a well-known high school, soIt cannot be ruled out that after school bullying occurred, the school urgently buried the existence of the facts."

Director Zhao looked at Han Ziyang: "What did you find out?" As expected of an old fox, he saw the door at a glance.

Comrade Old Han was waiting for his question: "Zhao Bureau, to be honest, you only give me this little manpower, it's really not easy to find out these things."

"Stop talking nonsense," Zhao Ju gave him a blank look, "Do you want to ask for a beating or a reward?"

"Ahem," Team Leader Han cleared his throat in embarrassment, "I sent someone to Bei Jing Comprehensive High School to get all the student materials that graduated between 2006 and 2009, and then compared them with the information registered at the police stations in each district., Confirmed 87 students who can be contacted and are still in Beijing, and then visited them one by one."

Director Zhao was surprised: "So much information, you got it all done in such a short time?"

Han Ziyang patted Xie Huai on the shoulder: "This is all thanks to Dr. Xie."

"Xie Huai said that he has a photographic memory, and it seems to be true." Bao Le was afraid that Jun Zhi would not understand, so he leaned into his ear and explained in a low voice.If she didn't explain, maybe Junzhi would go in from one ear to the other and come out from the right. When she explained this, Jun's eyes on Xie turned three points cold.

Han Ziyang continued: "After the visit, we found that there was indeed some disharmony in Beijing Comprehensive High School. It is rumored that there are two factions among the students of Beijing Comprehensive High School, one group has particularly good grades but no money at home, and the other groupIt is a family that is very rich but has poor grades. The boy who jumped off the building belongs to the former, while Zhu Yan belongs to the latter. Not only Zhu Yan, but also Luo Xin, Chen Xiaocheng, Cheng Jiashi, Xiang Yi and Hou Mingjun, also known as Nv LuoshanThe four corpses on the Internet and the victims of the Nan Jing case, a total of five people. There are testimonies that prove that they were very good friends. They both studied at Beijing Comprehensive High School in 2006, and their families were either rich, or have power, they are all figures that the school cannot afford to offend."

"During the investigation, we made some new discoveries, Gao Xing."

As soon as the little apprentice heard the master calling his name, he knew that his opportunity to perform had come, so he hurriedly projected the materials in his hand to the screen.Those in his hand were the personal data of a man named "Zhang Jian". Bao Le suddenly found that this man named Zhang Jian was familiar to her... That kind of familiarity was when she saw Luo Xin and Chen Xiaocheng.They've all been in photos.

Gao Xing: "Zhang Jian, male, 33 years old, studied in Beijing Comprehensive High School in 2006. According to his classmates at the time, Zhang Jian's grades were very good, but because his family was very poor, he had been living on a scholarship, and he usually had breakfastHe was reluctant to eat, and he was good friends with the boy who jumped off the building in 2006. We suspect that when he was studying in Beijing Comprehensive High School, he was also bullied on campus, so he had a motive to kill Luo Xin and his group. Zhang Jian committed suicide in 2007After graduating from Beijing Comprehensive Middle School, he was admitted to Peking University and studied at the School of Medicine of Peking University. He was recommended for graduate students in 12 years and graduated with a doctorate in 18 years. He is currently the deputy director of surgery at Beijiao Hospital. After the case of Nv Luoshan, heI asked for a long vacation, and now I'm missing."

Director Zhao rubbed his chin: "Male, right-handed, about 1.7 meters tall, well-proportioned, and a surgeon. In this way, he is the most likely suspect?"

Facing his boss's boss's questioning, the little apprentice rubbed his hands nervously, nodding his head like pounding garlic.

"Is there any clue about him?"

"About this," Han Ziyang stood up suddenly, turned around and looked back, his action caused more than 20 people in the conference room to turn their heads along with him, "I would like to invite a specialCome on stage and explain it to us, come on.”

Han Ziyang waved to Bao Le, as they had discussed before the meeting, she had already expected this link.

The little girl took a deep breath, stood up calmly, and then walked to the stage while everyone was watching, and took the microphone from Gao Xing calmly.She was wearing a hat and a mask, and no one knew where this girl came from or who she was.But when she slowly took off the mask and uncovered the hat, so that her face was completely exposed to everyone's eyes, there were endless sounds of shock.

As for Xie Huai who already knew who she was, he looked at Han Ziyang in shock.If it wasn't for Zhao Ju sitting next to him, he looked like he was about to punch up, so Han Ziyang quietly hid behind Zhao Ju.

Bao Le aimed at the microphone and interrupted everyone's whispering: "Everyone in the task force, everyone must be very impressed with my face, after all, my face used to appear in the victim column. ButIn fact, Jiang Baole, who died in the 17-year serial murder case, is my twin sister."

I don't know who came up with the idea of twin sisters, Xie Huai gave Han Ziyang a hard look, and then looked back at Bao Le on stage.

"I mentioned before that my sister may be related to the car accident in 2006, because she may have been a witness at that time, so the murderer killed her to silence her. I have been in Nan Jing all these years, and I was also an eyewitness to the case in NanjingOne. I don’t know if it’s because the murderer found me when he killed Luo Xin and wondered why I wasn’t dead, so he killed me twice after that. What I want to talk about is these two cases.”

"One time he mistook me for a friend who looked a bit like me. Fortunately, she was discovered in time and her life was not in danger. The other time was when I was with my friend in the hospital. He neverThe back strangled my neck."

Gao Xing cooperated with Bao Le's words and released the surveillance they found at that time.In the Wal-Mart surveillance, the scene that is highly similar to the murder scene is convincing.

The little girl also said: "There were two people in the ward at the time. It is not yet confirmed whether they are all related to the case, but one of them really wanted to kill me. He was a little taller than me, about 1.7 meters tall.He should have been in ambush in the ward long ago. He had a lot of time to attack my friend, but he didn't, so his target was me from the beginning. In addition, I scratched him, so when his hands and wrists movedAbout ten centimeters above, there should be scars."

Gao Xing continued her words: "Afterwards, I thoroughly checked the monitoring of boarding at the airport and the entry and exit records of the gates of the Academy of Fine Arts according to what Master said. I found that Zhang Jian had arrived in Ningxia on November 27, and went to Nan Jing on December 3.Back to Beijing, he didn’t use his ID card. According to the name of his fake |ID|ID|, we found in the entry and exit records that he visited the Academy of Fine Arts just after he arrived in Nanjing. Therefore, Zhang Jian is now very suspicious.”

After Zhao Ju listened silently, he turned to Han Ziyang and whispered a few words.After the other party nodded, Zhao Ju, who was like an old fox, understood completely.

"Okay," Director Zhao said, "I'll approve a note, and you guys go to arrest people. This case has too much impact on the society now, so you must be careful and close the case as soon as possible."

Team leader Han nodded: "Don't worry, leave it to me."

Seeing that the meeting is basically over here, the remaining work is nothing more than Han Ziyang, the leader of the task force, assigning tasks to the following groups according to the content of today's meeting.In fact, everything that should be said has been said, only Bao Le is still thinking about "The Twelve Chapters of Yin and Yang".

"Wait," the little girl finally said, and stopped Zhao Ju who was about to leave, "I think I know about the cradle, cart, and the quartz sand, snow, and foam that the deceased was on.What do you mean?"

She didn't tell Han Ziyang about this beforehand, Team Leader Han was a little surprised what she was going to say.

"This is an ancient book called "The Twelve Chapters of Yin and Yang." Bao Le took out the book he had brought from home from his bag. "My friend was attacked before, and I heard that the murderer carried this book. Originally, II have never figured out what this book has to do with the case. It was not until this morning that I came up with some new ideas. But this ancient book is an oracle bone inscription, and I can’t fully understand it. It’s just that the ancients believed that white is a pure color, andThe swaddle that wraps the child means a new life. So I guess, after the murderer kills the person, puts it in a cart like a cradle, and then sprinkles white particles all over his body, which means atonement. This also exactly corresponds toZhang Jian's motive for killing is that he wants those who bullied him to atone for his actions."

After the little girl finished speaking, she dejectedly said, "I'm not a major in ancient characters, and I can only interpret this book at random. I don't know if there are any misunderstandings."

This child Bao Le was born to be liked by the elders. Seeing her like this, Director Zhao's heart melted, and he hurriedly comforted her: "You have done a good job, this clue is very important." Then he glanced at the special case againThe others in the group, seriously educated: "You should also study hard, you must have your own thinking when investigating cases, and don't investigate deadly cases or death cases."

Everyone responded quickly.

Before Zhao Ju left, he patted Han Ziyang on the shoulder, and asked him in a low voice, "Do you think I have to give her a raise?" Xie Huai was the closest to Han Ziyang at that time, and looked at Team Leader Han with a ghostly look on his face.One couldn't help but laughed out loud.

...

After the meeting, the task force went to work one after another.

Only Qin Yao chatted with Bao Le: "If I can find you a person who specializes in ancient characters, will it be very helpful for you to decipher the content of this book?"

The little girl nodded vigorously, her eyes shining.

This glamorous forensic doctor with big waves smiled and took out her mobile phone from her pocket, dialed a number very skillfully, and soon she gestured "OK" to her.About half an hour later, a silver car drove into the police station, and an old acquaintance appeared at the door of the task force.

Shen Yan got out of the elevator and looked around. After seeing Qin Yao, the dusty Professor Shen Da reached out and pushed the glasses frame.
