The Book of Death by Heart Poison

Rongming Branch of Chuanming City.

Two corpses that had been thawed for more than 24 hours were placed on the forensic workbench, exuding the smell of corpses.

Hua Chong and Liu Zhiqin quickly arrived from the scene of the corpse throwing, and changed into isolation suits before entering the autopsy room.

"The state of the corpse is relatively rare." Before the autopsy began, Pei Qing held the head of corpse No. 1 (Wang Yuxia) and said, "Her two eyeballs were cut off, and now there are two 'night pearls' placed in the eye sockets." .”

Liu Zhiqin took the so-called "Night Pearl" and turned it around in his hand.This is actually a small bouncy ball for children, about the size of a table tennis ball. It is made of light-absorbing material and will fluoresce when placed in a dark environment.

"In Wang Yuxia's eyes, it's pink, and in Zhang Xu's eyes, it's blue." Pei Qing took out all four bouncy balls, "At present, I still can't figure out what the murderer's meaning is. What do color and blue represent?"

"If you think about it in a simple direction, it might just represent gender." Liu Zhiqin put down the bouncy ball, "Red represents women, and blue represents men's surnames."

Hua Chong approached, "Deliberately using red and blue to distinguish between men and women, the murderer has a stereotyped trait in his character."

Pei Qing looked at the two of them and paused, "Is it that simple?"

"Huh?" Hua Chong raised his eyebrows, "I'm just talking about my thoughts."

Pei Qing muttered: "I thought you would get inspiration for horror from 'Night Pearl'."

Hua Chong shook his head, "When sorting out clues, the more divergent thinking is, the more helpful it is for the investigation. It is unnecessary now. You said before that the murderer planned to make them into specimens?"

"Yes, but it doesn't look successful." Pei Qing turned corpse No. 1 into a side-lying position, exposing the two incision marks on the back, chest and abdomen, "There are two ways to make specimens in the animal kingdom, one is dipping, and the other is It is stripping. Impregnating is soaking animal carcasses in alcohol or formaldehyde solution, or directly injecting them into animals, just like using formalin (formaldehyde solution) to preserve human corpses in medicine. Stripping is peeling off the chest, abdomen or back , deboning, cleaning the head, etc.”

Liu Zhiqin frowned upon hearing this.

Pei Qing said again: "But obviously, the murderer failed in both methods."

Hua Chong turned his attention to the two corpses, "If the corpses are made into specimens, the corpses will no longer rot, but now they are still rotten."

"Yes." Pei Qing unfolded the incision on the back of corpse No. 1. "The victim's main internal organs have been removed, and the abdomen is empty, but the lungs and heart are still in the body. Only the eyeballs have been removed from the head, and the brain is still there. Regarding the specimen, the murderer should be very amateur, he took it for granted that as long as there is a suitable preservative solution and the internal organs are removed, the specimen can be produced, but in fact it is not that simple at all.”

Liu Zhiqin walked around to the body of No. 2, "What is the cause of death?"

"The initial suspicion is arsenic poisoning." Pei Qing said: "Arsenic can preserve corpses, and it is also a deadly poison. The arsenic I extracted from the corpses should be used to preserve corpses, but since the murderer has a lot of arsenic, it is also possible to use it for poisoning." It's understandable. Both victims experienced repeated freezing and thawing after their deaths, partial decay, loss of eyeballs, liver and kidneys, and it's difficult to judge the specific time and cause of death from the body surface, but..."

As she spoke, Pei Qing raised the head of corpse No. 1 again, "In her nasal cavity and mouth, you can still see traces of erosion and bleeding, which is consistent with the characteristics of death caused by arsenic poisoning. Check the respiratory system."

Hua Chong said: "It is difficult to judge the exact time of death, so can we judge whether the murderer froze the victim first or made specimens first?"

Pei Qing nodded, "Frozen first, Wang Yuxia was frozen for a longer period of time. Judging from the rot, I think the murderer started to make specimens of the two corpses at the same time after killing Zhang Xu. But because they were unsuccessful, the corpses gradually rotted. The murderer put them in the freezer again, took them out and tried again, and repeated the process until yesterday when they were thawed and buried in a sandpit."

Leaving the dissecting room, Hua Chong and Liu Zhiqin helped each other spray disinfectant, and then changed their isolation suits.

"The condition of the corpse was beyond my expectation." Hua Chong said, "A specimen? How could it be a specimen?"

"But the corpses appeared, so I finally got some clues." The autopsy room is still the forensic doctor's work area, and there are no idlers. Liu Zhiqin sat on a long bench and said, "The murderer must have a car to move the two corpses. The car is very ordinary, unremarkable on the edge of the city. The murderer’s home, no, it’s not necessarily a home, it may be a place where he hides and disposes of corpses, and there is a large freezer that can hold two to four corpses.”

Hua Chong walked back and forth in front of the bench, "The other two missing persons, Xu Yufan and Jia Bing, may also have been made into specimens by the murderer..."

As he said that, Hua Chong shook his head, "The only ones who could be made into specimens are Wang Yuxia and Zhang Xu. The murderer's experiment on them failed, and he may not continue to try this kind of experiment."

"The question now is, what does a specimen represent?" Liu Zhiqin said: "Under normal circumstances, there are two main purposes for making specimens, one is for teaching and popularizing science, similar to animal specimens in schools and exhibition halls, and the other is The specimen itself is of great significance to the owner, for example, after the death of the pet, the owner misses it and makes it into a specimen for permanent preservation.”

Liu Zhiqin stood up, "Bringing it into the case, the two situations do not conform to the murderer's logic."

Hua Chong thought for a while, "The murderer stripped the victim's skin and cramps to make a human skeleton, or dismembered the victim's body, and put the important parts in preservation solution for long-term storage—this kind of cases can be found both at home and abroad. But these cases have a characteristic , the murderer has unusually strong feelings for the victim, and exists at a key link in the victim's interpersonal network."

Liu Zhiqin said: "But obviously, our murderer doesn't have such a deep relationship with the victim."

"This is also what I don't understand." Hua Chong folded his arms, "The corpse has been repeatedly frozen and thawed. When the murderer hadn't mastered the correct method of making specimens, he tried his hand at the corpse. The method was so amateur that the corpse It started to rot. Let me infer his specimen making process—put it in the freezer and freeze it first, then suddenly found out the method of making specimens, took it out and thawed it out, started from the simplest eye digging, stuffed it with cheap elastic balls, and injected it for preservation Oops, it’s rotten, the smell overflows, and it’s re-frozen; after a while, I still want to make a specimen and take it out. This time, let’s peel off the internal organs first. The internal organs are the easiest to rot, but the heart and lungs cannot be removed, and the bones can’t be removed. It’s not clean, forget it, freeze it again…”

"Perfunctory." Liu Zhiqin said suddenly: "The murderer's mentality is very perfunctory. He is not doing this with strong emotions, but only needs one result, which is to make a specimen. The elasticity he used to replace the eyeballs The balls are made of low-quality rubber and plastic, costing no more than three yuan each. For real specimens, the eyeballs are replaced by refined glass balls."

"Wait a minute." Hua Chong raised his hand, "If you were a murderer and you wanted to make specimens, would you buy that bouncy ball?"

Liu Zhiqin raised his eyes.

Hua Chong said: "That kind of bouncy ball is cheap, but it's not very common. Only younger students can play bouncy ball. Middle school students, especially high school students, probably don't know how to play bouncy ball?"

Liu Zhiqin said slowly: "You mean..."

At this moment, a policeman from the branch came to the forensic work area. Judging by his rank, he was a young policeman with little experience.

Hua Chong greeted the other party, picked up the evidence bag, and asked, "Do you know what this is?"

The young policeman looked at it for a long time, "What ball?"

Hua Chong asked again: "Where can this kind of ball be sold?"

The young policeman blushed, "I, I don't know. I haven't seen it."

Hua Chong smiled at the other party, "It's okay, I'll ask casually, and go about your business."

The young policeman walked away blankly, Hua Chong raised his eyebrows at Liu Zhiqin, "Look, although you, me, and Pei Qing can tell what kind of ball it is, and know that it can be bought at the canteen near the primary and secondary schools, But the little policeman just didn’t know. In other words, most adults didn’t know what it was for when they first saw it, let alone where to buy it. This “knowledge” is a bit biased. We Relying on the experience of visiting around for a long time, what did the murderer rely on?"

Hua Chong paused, staring at the bouncy ball in the evidence bag, "Or, why did the murderer choose this kind of ball that ordinary people would not choose?"

"In his cognition, this is the most common ball. When he needed two balls to replace his eyeballs, he first thought of the bouncy balls that can be bought near the school." Liu Zhiqin took a few steps, Turning around, "He is very familiar with the school, he may be..."

"No." Liu Zhiqin shook his head, "He may not be someone who is closely related to the school, he has followed the victim, and when he was waiting for the victim outside the campus, he probably visited a nearby shop and found out at that time Bouncy Ball."

"But the high school and junior high school of the [-]th Middle School are separated, and the murderer is wandering around the high school of the [-]th Middle School and Jianshan Vocational High School. Is it possible to see the bouncy ball?" Hua Chong said: "There are bouncing balls outside every elementary school. , in some junior high schools, but in high school, no high school student will play this kind of thing, right?"

Liu Zhiqin immediately understood, "The murderer may be the teaching staff of the elementary school!"

"To be on the safe side, the scope can be extended to junior high schools." Hua Chong said, pursing his lower lip, "However, this is also an inference based on the bouncy ball, which can be added to the murderer's profile, but we cannot follow this inference completely. Thinking in another direction, maybe the murderer is related to the bouncy ball production industry.”

"So the key lies in the specimen." Liu Zhiqin said: "Flower Team, do you think this is some kind of ritual of the murderer?"

In many non-passionate homicides, the corpse and the scene will appear ritualistic.A large number of cases have proved that the more abnormal the murderer's psychology, the stronger the desire to pursue ritual.They are even willing to expose themselves for the sake of rituals that are difficult for others to understand.

Some cases were finally solved because of the ritualistic nature of the murderer.

"A perfunctory ritual." Hua Chong said: "It's quite rare to be perfunctory to this extent. He seems to just want to tell people who saw the corpse that these are two specimens."

Later, Pei Qing completed the autopsies of the two corpses. The liver and kidneys were the most obvious reaction to the death caused by arsenic poisoning.Both Wang Yuxia and Zhang Xu suffered from toxic cardiomyopathy, with respiratory paralysis in the lungs and throat, and they were determined to have died from arsenic.

"I also found some details." Pei Qing said: "Before Wang Yuxia died, she was bound for a long time with a silk rope. After the murderer killed her, she didn't untie the rope immediately. But there was no other torture on her body. Traces. This kind of situation is actually relatively rare.”

Liu Zhiqin said: "Generally, cases involving bondage before and after death have a certain degree of abuse. It's either pure venting or revenge. The last case was like this."

"Yeah. But the murderer didn't do anything to her other than tying Wang Yuxia up." Pei Qing said, "The way of tying her up is just a normal way, with her arms tied behind her back and her legs tied at the knees and calves."

Hua Chong scanned the detailed autopsy report, "The purpose may be to restrict the victim's actions."

During the autopsy, the forensic doctor had to stand the whole time. Pei Qing moved a chair and let out a sigh of relief when she sat down.

Liu Zhiqin said: "You just sit here? Are you leaving?"

"Let me rest first. Two days ago, Hai Zi said that I was the oil bottle for you two, but today I have solved two consecutively, and I am not used to it." Pei Qing said.

Hua Chong's eyelids twitched, feeling rather speechless, "You don't seem to use the oil bottle like this?"

"Really?" Pei Qing scratched her hair, "Then criticize Hai Zi, he said so, I'm just repeating."

Haizi, who was working hard at Minggang Primary School, sneezed.

"Are you still not used to it? You did ten autopsies in a row and you didn't say you would take a break." Liu Zhiqin exposed it bluntly, "I think you just want to eavesdrop on me discussing the case with the flower team."

"Hey! I'm not eavesdropping. I moved the chair openly." Pei Qing said and patted the chair twice, "I'm also a member of the criminal investigation team, I should listen!"

Hua Chong laughed and said, "I didn't say you shouldn't listen."

Although it hasn't been long since the special operations team was transferred, Hua Chong has already figured out the temperament of all the team members.

In terms of technology, Pei Qing is certainly an excellent forensic doctor.But this person has a high self-esteem, and he looks down on basic investigations, thinking that the corpse can speak, and all decisive evidence exists on the corpse.Once he finished his work, he would be indifferent to the next investigation.

The first case that Hua Chonglai's special operations team handled, Pei Qing was sent to visit with Yue Yue.

At that time, the noble forensic doctor Pei was still very reluctant.At the time, Hua Chong didn't know that Pei Qing was very resistant to basic research, so he didn't do ideological work for others.

As a result, when the case was investigated, Pei Qing seemed to have opened up the two channels of Ren and Du, and experienced the beauty of cooperative investigation for the first time.In addition, the nemesis, Hai Zi, would talk to him when he had nothing to do, saying that he only knows how to dissect and is useless except dissecting, and that the flower team is a comprehensive talent. In the future, everyone in the criminal investigation team will also develop into a comprehensive talent. .

Forensic doctor Gaogui panicked for the first time, not only rushed to participate in the investigation, but also rushed to participate in the inquiry. Although he didn't speak much during the case review meeting, he listened more seriously than anyone else.

The enthusiasm of the team members is high, and Hua Chong certainly welcomes them.

"Why don't you tell me what you think." Hua Chong said.

"Me?" Pei Qing wanted to say "I have no idea" subconsciously, but when she thought of Haizi's face that deserved a beating, she swallowed the words that came to her lips.

The surname Hai has a strong desire to perform, even if he has nothing in his mind, he will gossip a lot, just like when he is studying, he obviously can't do reading questions, but he has to improvise, at least he can get hard points.

It's not difficult, Pei Qing thought, and I will too!

"I think these cases are very divisive." Although she wanted to improvise in her heart, but when she really spoke, Pei Qing became serious, "On the corpse, I can't feel the murderer's strong hatred for the victim. He seems to be casual They killed two people. But connecting the four cases, the murderer targeted the teacher group. I think he hated the teacher. Maybe a teacher once did something to him. He couldn’t take revenge on this teacher, so he vented his anger on the teacher. This teacher has similarities in people."

"Wait a minute, it's hard to tell the similarities." Pei Qing said again: "In short, the murderer should have a clear hatred for the teachers, but his killing process, specimen making process, and even yesterday's behavior of throwing the corpse, It seems to be too casual, and he can't bear his hatred at all. Does he not hate? If he doesn't hate, why do he continue to commit murder?"

Hua Chong turned to Liu Zhiqin, "It's too casual, in fact, it's the perfunctory we just mentioned."

For serial killers, killing a person is a process of enjoyment.

When enjoying, why are you perfunctory and casual?

"That's why I feel that his hatred doesn't seem that deep." After finishing speaking, Pei Qing added: "The hatred is still deep, but the hatred for the victim and the teacher group is not that deep."

Hua Chong's eyes flashed suddenly.

Pei Qing was stunned for a moment, and reservedly looked for a way out for herself, "Am I making no sense? After all, I'm just a forensic doctor, and you are experts in reasoning."

"No, it makes sense." Liu Zhiqin smiled, "The perspective of the forensic doctor is novel, thinking of something that Team Hua and I haven't thought of yet."

Pei Qing: "Huh?"

"The murderer chooses teachers to kill in a row. Naturally, he has hatred in his heart." Hua Chong said: "But what he hates is not necessarily the people he killed. He may be killing these people and showing them now." The corpse that was made into a specimen, poured out the deeper hatred buried in his heart."

"It's not the person you hate..." Pei Qing asked, "But if that's the case, why didn't the murderer kill the person you really hated?"

Hua Chong felt that he had grasped the key point, "Because he couldn't attack that person, those people. As for why he couldn't, there are too many reasons."

"Flower team." Liu Zhiqin said: "Based on our judgment just now, the murderer replaced the eyeballs with bouncy balls. There is a high probability that they are teachers and staff of elementary or junior high schools. Now I think this profile can be used for investigation. He told teachers The crowd has no hatred, and is himself a teacher, or a close associate of a teacher."
