Fu Xinjie: "He went to a high-class club last night, and he often goes there to play. The waiter at the club said he left late last night. The young man who parked the valet said he had come in a green Ferrari and had driven it away. Chen Qiangjian was drunk and drugged, and he shouldn't have driven by himself. But the lad said he had always been like this and liked the thrill. ”

Long Xi thought of his parents who were killed by a drunk driver, and said unhappily: "He is excited, is other people's lives so worthless?"

Fu Xinjie said: "How can a person like him care about the life and death of others? When he arrived at the Chen family's villa, he washed and slept. The Chen family has a good security security system, and the security guards always thought that he slept in his room because he was sleeping in the room all the time on the screen. Our professional computer technicians found out that the security system of the Chen family was hacked last night, and the program was modified, and the real picture was covered by the previous video footage, and nothing was taken. ”

Long Xi asked, "What about the school's cameras?"

Fu Xinjie asked: "We looked at the school's monitors, and the front and back doors of the school were locked all night, and there was no record of anyone entering or leaving. The two security guards were also on duty all night, did not sleep lazily, and did not see anyone coming in or out. Based on these clues, we preliminarily concluded that the murderer did not go up the mountain from the school. ”

Long Xi asked, "What is the time of his death?"

Fu Xinjie: "The autopsy report is out. The medical examiner thought it was between two and three o'clock last night. ”

Long Xi: "I saw that the face of the corpse was dark purple, could it be poisoning?"

Fu Xinjie said: "No, if you are poisoned, your body will also turn black." Moreover, after the autopsy, no evidence of poisoning was found. The deceased's heart is of normal size, and if the poison enters the body through the esophagus or respiratory tract, the heart will swell or constrict. There was a small amount of sleeping pills left in his stomach, but the amount was far from enough to kill anyone. ”

Long Xi: "He has a lot of wounds on his body, could it be that poison was injected from the wound and entered the blood circulation?"

Fu Xinjie: "Impossible. If this is the case, the heart will also enlarge or constrict. ”

Long Xi: "What is the cause of death? Excessive blood loss, strangulation?"

Fu Xinjie said: "Although there are strangulation marks on his neck, he was not strangled to death. He must have been hung after he died. In addition, although there were many wounds on his body, there was not much blood at the scene, which indicates that the place where the body was found was probably not the first scene of the murder. The eight blood characters on the wall, which have been identified as matching the DNA of the deceased, are written in his blood. ”

Long Xi asked, "What is the cause of death?"

Fu Xinjie said: "The cause of his death was very strange, it was that there was no air in his lungs. ”

Long Xi asked, "There is no air in the lungs, is that suffocation or choking?"

Fu Xinjie said: "It's strange, their airway is very smooth. ”

Long Xi said: "The airway is smooth, then it is not suffocation or choking." ”

Fu Xinjie smiled, and then continued: "Little girl, you seem to know quite a bit! Do you plan to take the policewoman exam in the future?"

Long Xi said: "It's not, it's not my dream to be a policewoman, I just like to read detective mystery novels." Is there any loss of property from the deceased?"

Fu Xinjie said: "The wallets are all there, there are a lot of credit cards in them, and there is not much cash. The WeChat wallet in the mobile phone has 22,327 yuan and three cents, which is connected to an ICBC bank card. WeChat wallet transaction records are realistic, the most recent expenditure is the day before yesterday, Chen Qiangjian bought a new car, which is a champagne-colored Ferrari sports car. The car is still in his garage and has not been used. His family said he prefers to pay by credit card, WeChat red envelope or Alipay, rather than cash. That's probably why he only has a small amount of cash in his wallet.

Long Xi asked, "Is there anything else strange?"

Fu Xinjie looked at the information saved on his mobile phone and said, "Teacher Xu handed over the blood letter to the police station, and after the appraisal of the experienced handwriting experts at the police station, he believed that the handwriting and the puppy pattern were indeed from Xu Xian'er himself. Moreover, after identification, the DNA of the blood used in this blood book is 99% consistent with Xu Xian'er's DNA. ”

Long Xi said: "That is to say, this blood book is not a forgery. Is it exactly the same as the original Blood Book?"

Fu Xinjie said in a confessional tone: "I have compared, it is almost identical, but there is a different punctuation mark, the previous one is a comma, and this one is a full stop." At that time, I burned the suicide note found in the girls' dormitory, and I took a picture with my mobile phone before burning it. ”

Long Xi pursed his lips and stopped talking.

Fu Xinjie said: "I want to defend myself, I really didn't do it for money. I have aspired to be a police officer since I was a child, because when I was a child, I used to encounter great dangers, and it was my police uncle who saved me. I want to be like my uncle a police officer. But Liu Dazhi told me that if I didn't compromise, then I couldn't continue to be a police officer. That's why I compromised. I donated that money to the orphanage, which is considered atonement. But my conscience has always been at rest, and I have nightmares at night. ”

Long Xi said: "If a person is not a sage, it is not too late to make amends." Sister Police Flower, your conscience is still clear, I believe that you will be a good policeman in the future! If the blood book is true, then Xu Xian'er is likely to have written two blood letters, one in the dormitory and one at home. Can I take a closer look at the corpse?"

Fu Xinjie shook his head and said, "Not everyone can enter the Forensic Science Department. Well, I took a few pictures of the corpses, and you take a closer look. ”

Long Xi looked at those photos for a while, and said to Fan Xiaolu, who had been blowing the cold wind with her, "I probably know what the cause of his death is." It seems that I was wrong, and Mr. Xu is the most suspicious. ”

"Why? Chen Qiangjian is so fat, with the strength of Mr. Xu alone, let alone killing, I'm afraid it is difficult to hang his body on a tree. Fan Xiaolu said. Like Long Xi, he sympathized with Teacher Xu and didn't want the murderer to be Teacher Xu.

"Yes, it is really difficult for him to do it alone. So, I suspect it's a coordinated killing. Mr. Xu uses his brain power, and his strength is rich knowledge of physics. And the other person should be stronger, using physical strength. Long Xi said.

"You mean that Teacher Xu used physics knowledge to kill people?" asked Mo Kun.
