May 201x.

Outside the VIP passage of Jinjing Railway Station, a middle-aged man in a police uniform was walking around anxiously, he looked at the exit of the passage from time to time, and his brows were furrowed tightly.

"Zhang Ju, it's useless for you to be in a hurry, their car still has twenty minutes to arrive at the station." The young man in a police uniform behind him was dizzy by his shaking eyes and couldn't help but say.

The man reached out and grabbed his hair that was a little messy: "I'm not in a hurry, can I not be in a hurry?" The gang of people in one group are all rubbish! can actually make people leak the news. Well, now everyone in the city knows that there is a perverted murderer in Jinjing. I think I'm the deputy director of the bureau and I'm done it to the end. ”

The man put his hands in his trouser pockets and turned around twice more: "A case has been investigated for half a year, and I haven't even seen the shadow of a murderer, and her mother is eating dry food." If you can't do it, you can say it early, but now it's good, the face of the Jinjing public security has been completely lost by them, not to mention, and they have to invite the special case team in......"

The little policeman listened to the man's whining and looked at the exit of the station casually, and suddenly he straightened up and pushed the person who was still reading: "Zhang Ju, they have arrived." ”

Zhang Fu turned his head to see that a group of six people in the VIP passage of the railway station were hurriedly walking out.

The man at the front is amazingly imposing, his tall figure is wrapped in a dark business suit, and the whole person looks like the CEO of a large company. Of course, the most eye-catching thing is not his outfit, but his eyes. His eyes are so sharp that he seems to be able to see the bottom of your heart at a glance, so that you subconsciously avoid his gaze and dare not look at him.

Zhang Fu walked a few steps briskly and stretched out his hand and said, "Finally looking forward to you, hello, I am Zhang Fu from the Municipal Bureau." ”

The man who walked in front shook his hand and said, "Hello Zhang Ju, I'm Shen Zezhi from the special case team." ”

Zhang Fu did not identify himself, but it was clear that the special case team had been prepared. Zhang Fu knew the style of the special case team, and he didn't talk nonsense: "The things you asked for are ready, let's leave now." ”

When they arrived at the office building of the Public Security Bureau, almost all the policemen stopped what they were doing and looked at them. But the people who were watched were very calm, obviously, they had already encountered a lot of such courtesy.

I can't blame everyone for looking at them, there are six members of the special case team, four men and two women, except for one grade that is a little older, the others are all handsome men and beautiful women. It's so eye-catching.

Zhang Fu didn't care about their thoughts at this time, he took the people from the special case team to the office prepared for them, and said directly: "You already know the basic facts of the case, right?" Now that the media has broken the case, a serial murder case of such a bad nature has not happened in Tianjin for decades. We must solve the case in the shortest possible time, otherwise the people will panic, and the rest will be left to you. ”

Shen Zezhi nodded: "Don't worry, Zhang Ju, we will definitely try to solve the case as soon as possible and catch the real murderer." ”

Time back three hours, Pingjing, Ministry of Public Security.

"We've got a job." Guan Xin told everyone to go to the conference room to learn about the case.

She used PPT to introduce the case this time, and photos of four people, three men and one woman, appeared on the big screen.

"So far, police have found a total of four deceased." She tapped the pad in her hand, and creepy photos appeared on the screen. Guan Xin introduced the case while flipping through the photos.

"This is the first deceased, Qin Qiaomei, female, 48 years old. According to the investigation, the owner of a small supermarket is divorced, and his only son works in the field. Currently lives alone. On January 19, her body was found in the laboratory of the Department of Forensic Medicine at Seung Eun Medical College. Here is a photo of the scene, you can take a look. ”

Guan Xin flipped through the photos to show everyone: "After a forensic examination, it was found that her deceased had suffered organ damage. The killer pierced the deceased's heart with a dagger or other weapon, causing death. ”

Everyone couldn't help frowning when they looked at the photos, although they had seen a lot of various crime scenes, but it was the first time they had seen such a pervert. The corpse's head was cut off, the body was cut open from the neck to the pubic area, and all the internal organs were removed and placed in a clear glass jar at the corpse's feet. The torso is not hung with an iron hook.

"Wait, what are these jars...... Animals? Kiko-more asked.

Concerned nodded: "It's the zodiac." According to the police's investigation, these jars were originally goldfish bowls, which can be bought everywhere in the craft market, night market, and flower and bird market in M City. I will continue to turn to the case. Her head had been cut off flat, and she had been stuck in a whip and placed across from the corpse, far away from it. The site was clean and there was no extra blood. It can be determined that the laboratory is not the first scene, and the body should have been disposed of and removed. ”

Shen Zezhi pondered for a while and said, "The deceased is not thin, it takes a certain amount of strength to move her over, needless to say, she has to hang up." It can be seen that it is unlikely that the murderer is a woman, and it should be a man. Judging by the direction of the deceased's fatal injuries on the corpse, the murderer should be at least ten to twenty centimeters taller than the deceased. The deceased was one meter six tall, so the murderer should be about one meter seven to one meter eight tall. ”

Qi Kai added: "Women generally wear high heels, maybe the murderer will be a little taller, he should be a stronger man."

Zhao Jiyong said: "According to experience, if you can kill a person like this and calmly divide and move the body, and plan carefully, it can be seen that he is not too young, at least about thirty years old." ”

"Beheading was used as a criminal law in ancient China to punish those who committed the most heinous crimes. The murderer cut off the deceased's head and made her head face his corpse, which shows that the murderer hated the deceased extremely psychologically, and even wanted the deceased to feel humiliated, even if she was dead. "Shen Ze's way.

Guan Xin opened the photo of the next deceased and said, "Okay, let's look at the second deceased." The deceased, Deng Ruoyi, female, 20 years old. A sophomore at the School of Economics, M City University of Finance and Economics. The deceased was found on January 31 in a remote alleyway in a university town. The deceased died of suffocation, and the murderer strangled the deceased with his bare hands. After a forensic examination, the deceased had not been sexually assaulted before his death, his clothes were fully dressed, his handbag was next to the body, and the cash and mobile phone in it were there, but the mobile phone was damaged, and the memory card inside was missing. ”

"It seems that the murderer should have used a mobile phone to contact the deceased before, and he destroyed her mobile phone for fear of revealing his identity?" Zhao Jiyong said.

Guan Xin shrugged and then began to introduce the third deceased.

"The third deceased, Yang Yun, female, 35 years old. The accountant of a local business in City M, the deceased died in his home. She died of blood loss, the killer slit her carotid artery, and the blood on her body was almost drained. Moreover, she had multiple abrasions on her body, and there were traces of violent sexual assault on her body. But the medical examiner did not find semen in the deceased's body, and the murderer used condoms or anything like that. And there's a pattern on the mirror in her bathroom, which is this. ”

A blood-red inverted five-pointed star appears on the screen. Ji Ziyue's brows moved.

"Wait, you say the blood of the dead is almost drained? How did the murderer do it? Sang Yunqing frowned and asked.

It is well known that platelets in human blood have a clotting effect. In general, the clotting factors in the blood of the wound will act, and even if the wound is too large, the blood will slowly coagulate and no longer continue to flow out.

Guan Xin said: "This is what I am going to say next, the forensic doctor detected acidic mucopolysaccharides in the body of the deceased. ”

Sang Yunqing showed a look of surprise, everyone else looked at her, Sang Yunqing explained: "Acidic mucopolysaccharide is mainly composed of two disaccharide units in sulfate-D-glucosamine, sulfate-L-iduronic acid, sulfate-D-glucosamine and D-glucuronic acid alternately linked, and is a mixture with a molecular weight of 5000~30000. ”

"What the hell is this?" Qi Kai listened in the clouds.

"Heparin." Sang Yunqing and Ji Ziyue said in unison.

Sang Yunqing smiled and said to Ji Ziyue: "It's an overseas doctor, and he has a wide range of knowledge." ”

Noriko smiled embarrassedly.

Sang Yunqing continued: "Heparin is an anticoagulant drug, which is clinically used to treat thromboembolic diseases and prevent thrombosis from forming and expanding, such as deep vein thrombosis, pulmonary embolism, cerebral embolism and acute myocardial infarction. Since this drug can only be injected intravenously, there should be pinholes in the deceased's body. ”

Guan Xin said: "The forensic doctor found a pinhole in the neck of the deceased. ”

Sang Yunqing said: "At present, there are only a few drugs containing heparin on the market, and the price is not cheap. The use of heparin has great side effects and certain dangers, and perhaps this is a breakthrough.

Guan Xin changed the photo of the fourth deceased and said: "Let's take a look at the last deceased, the deceased Fu Xin, male, 16 years old. He is a sophomore at the No. 1 Middle School in M City. His body was found in the playground on March 17. The deceased died of suffocation, and the murderer strangled him with a rope. And. Guan Xin paused for a moment and continued: "When he found his body, he was completely naked, only his face was painted with oil paint. That's it. ”

The face of the deceased appears on the big screen, which is in the shape of a clown.

Qi Kai asked: "Four dead people and four methods, how can you be sure that this is a murderer?" ”

Guan Xin nodded and said, "This question is very critical, apparently the criminal investigators in M City also thought of it, and they found the same thing on the four deceased - this is it." ”

Four close-up photos of the arms appear on the screen.

Shen Zezhi frowned: "What is this?" ”

Guan Xin said: "It should be a totem, which is branded on the inside of the deceased's left wrist." ”

After listening to Guan Xin's introduction, there was a brief silence in the conference room. Apparently they are dealing with an elusive psychopathic murderer. The most important thing is that these four deceased people are different from their social backgrounds to their methods of death. People don't know where to start.

"What did Ziyue think of?" Fukasawa asked suddenly.

Noriko returned to her senses and said, "I think the way these dead people died is very familiar. I think it's likely that the murderer was a copyist. ”

Everyone's interest was aroused. Shen Zezhi asked, "What do you mean?" ”

Ji Ziyue took Guan Xin's pad and pulled up a few photos and said, "Let's talk about the two most obvious first, the third deceased and the fourth deceased." The inverted pentagram on the bathroom glass of the third deceased, Yang Yun, is an important symbol of the crime committed by Richard Rewa Ramitis, one of the world's top 10 killers. He is a famous American serial killer, nicknamed 'Devil's Disciple', who once caused a sensational bloody case in the United States.

He is said to have killed at least 19 people, the exact number is unknown. He began killing people on 28 June 1984 and did not stop committing crimes until he was caught on 31 August 1985. Richard kills people without a fixed goal. He randomly chooses his 'prey', which is mainly female, and if there is a male next to the female, it is usually a headshot. He likes to sneak into someone's home at night, then shoot or strangle adult males, violently rape, kill, and dismember women and children, leaving his mark on the aftermath - an inverted pentagram on the wall, in the mirror, and even on the deceased. So seeing this inverted pentagram made me think of him. ”

Ji Ziyue put a close-up of the face of the fourth deceased on the screen and said, "And his face reminds me of another homicidal maniac, killerclown, a murderous clown." His real name was John Wayne Garcy. He is a native of Chicago, USA. Garcy killed people between December 1972 and December 1978, and he killed 33 people in six years. He was bisexual, and the trigger for the murder was supposed to be that he was molested by a same-sex friend of his family when he was nine years old. Unlike other psychopathic murderers, Garcy has a good social appearance and identity, and he also joined the local 'Jokers' club, designing a unique clown image for himself, the 'Stilt Clown', to perform for the audience at various party parades and fundraising ceremonies in Chicago.

Garcy is a serial killer diagnosed with an antisocial personality who is relatable, and always makes a good first impression. But the appearance of these 'model youths' is more like his usual disguise, and the clown performance is like showing his true side to others. And the fourth deceased, Fu Xin, was painted with the face of a clown by the murderer after his death, which shows that he is likely to imitate Garcy to commit the crime. ”

Shen Zezhi: "Generally, imitation crimes are imitations of a murderer's behavior, and it is very unusual for him to imitate multiple famous perverted murderers. Judging from the methods and frequency of his crimes, this person is extremely confident, and he is very sure that the police will not be able to arrest him, and his actions are almost provoking the police. It should be noted that the murderer was extremely vicious and showed no mercy for the deceased, and depending on the frequency of his crimes, it is likely that he will continue to kill. ”

Guan Xin: "So the Jinjing City Public Security Bureau asked us for help, and all the materials have been sealed, just waiting for us to pass." ”

Shen Zhize stood up and said, "Okay, let's go to Jinjing City." Mr. Zhao went to investigate the situation of the first deceased, Qi Kai was the second, and Ziyue and I investigated the last two deceased. Yun Qing was in charge of the bodies of the deceased, and all the bodies were re-autopsied. Guan Xin gave us network technical support. Depart in twenty minutes. ”

"Yes."
