According to the description of medical examiner Xu Junhao, the homeless man is a very miserable person.
He lives in the intersection between human society and the jungle. Sometimes he is a human, sometimes he is an animal. Even when he is a human, he hardly gets the respect that a human should get.
Many people who come and go in the park just think he is a stone, which is good enough. Some passers-by even think he is shit, and they have to take a detour when they see him. Some even fan the air blowing in the direction of the homeless man with disgust.
But in the flow image, Yi Jiayi saw the homeless man, and was shocked to see his appearance and state.
He was not sad, nor did he look sad and miserable. He even looked very happy and innocent.
Liang Xiaofu smiled widely, showing both rows of teeth. Jiayi walked hurriedly on the Xiangjiang Road. It was rare to see someone who looked happier than him in a few days or weeks.
Ordinary people looked down on his dirty, smelly, stupid and crazy appearance. The crazy Liang Xiaofu was even more disdainful of understanding the views of passers-by. He lived in his own crazy world. Maybe his mental state was better than many normal people.
It was late at night. There was no one else in the park. Only wild cats occasionally got up and chased mice into the bushes on the other side. After a rustling sound, they disappeared into the night.
Liang Xiaofu was not afraid. He wandered in the park and became the king who patrolled the territory. He did not need to avoid passers-by and was more crazy and free.
On a jogging path, he picked up a 5-mosquito-paper note (5 yuan) and jumped up in place with joy. He spread it out and looked at it under the street light, but he couldn't see enough. He folded it and hid it. After a while, he took it out and looked at it again. He really liked it.
Later, he saw a person in his park. He was wearing black clothes, a black hood and a black mask. He also wore a pair of sunglasses late at night. It was very weird, but the homeless man didn't think it was weird. He didn't have the concept of "weird".
The man was not tall and wore loose clothes. When he walked, the clothes occasionally stuck to his body, which showed that he had a thin figure.
The homeless man passed by the stranger, who had clearly passed by, but stopped and looked back, hesitated for a while, and then asked: "Do you want to eat meat?"
...
Jiayi immediately recorded in her notebook:
[slender figure]
[about half a finger taller than the homeless man]
[wearing sunglasses and a mask: came prepared]
[brought meat]
...
The homeless man sat on the bench and happily ate the meat given to him by the stranger.
The stranger sat next to him, sometimes looking forward in a daze, sometimes looking at the homeless man, and only got up and left after the other party had eaten all the meat.
But he did not walk away, but stood behind a tree a few steps away and observed the homeless man.
Later, the homeless man covered his stomach and began to roll on the bench. He groaned in pain, blood flowed from his nose, and he began to howl again, rolling off the bench to the ground, picking up more dirt and grass as he continued to roll.
The man in black looked for a long time before walking towards the homeless man.
He was a little nervous at first, and kept looking left and right, afraid that someone would suddenly approach this area.
But gradually, something stimulated him and he was no longer afraid. He even felt unbearable because he couldn't see the homeless man's painful expression through his sunglasses -
he took off his glasses.
Two straight and long eyebrows, not twisted or arched, showed that their owner did not show any intense expression even in the face of such a tragic situation.
Under the eyebrows were a pair of not small eyes, double eyelids, and some fine wrinkles at the end of the eyes.
He carefully folded his sunglasses and put them in his pocket. He stood beside the homeless man like a street lamp, looking down at the man writhing in pain, unwilling to miss even a single frame of such a scene.
…
Jiayi felt a little suffocated in her chest, such a dark tone, such a quiet and strange scene…
But even though her emotions fluctuated, her hands did not stop, and her writing was still steady:
[Double eyelids, slightly depressed at the end of the eye, wrinkled, long flat eyebrows]
and drew a simple and rough sketch of the murderer's eyebrows and eyes next to the handwriting.
She also read the scenes in the mind stream carefully, unwilling to miss any of them.
After watching it for the first time, she added new information during the second viewing:
[The finger joints are not thick]
[The nails are neatly trimmed and the fingers are clean.]
[There is a bulge on the first section of the middle finger, caused by writing?]
...
The man in black was getting more and more courageous during the few hours he spent with the homeless man.
It turns out that under the trend of **, people can transform from a cautious attempt to a brutal beast in such a short time.
The man in black seemed to be unable to wait for the homeless man to die so slowly under the torture of the toxin. He pulled out the baseball bat that was tucked into his waistband and hidden in his wide trouser legs, aimed at the back of the homeless man's head, and even aimed before hitting him hard.
As the homeless man twitched and fell into a semi-fainting state, the man in black became more reassured. He put on the gloves and shoe covers he had prepared in advance, grabbed the homeless man by the collar, and dragged him into a more hidden area among the trees. He
then took out a knife and squatted beside the homeless man, as cautious and solemn as a surgeon about to perform an operation.
He hesitated and first covered the homeless man's eyes with his gloves, but when he withdrew his hand, the homeless man still opened his eyes wide to see him clearly.
This made the man in black a little annoyed, and his eyebrows finally wrinkled slightly. He simply rolled up some dirt to stuff the homeless man's mouth, lifted the homeless man's clothes, and covered his head with it.
Then, he brought a big stone to press down one of the homeless man's hands, and stepped on the other hand with his foot to prevent it from interfering with his "operation".
Everything was ready, and the man in black began his exploration while the homeless man was still alive.
[Exploration]
Jiayi described it this way in her notebook.
Because the murderer did not stab the victim's belly with a knife, he carefully pressed on the homeless man's belly, and then used the knife to measure his dirty and black belly before cutting.
This series of actions was like exploration, like a medical student dissecting a cadaver, carefully holding a certain cautious and serious emotion, cherishing this opportunity to try dissection, and enjoying such an opportunity.
He cut slowly, cutting a little bit, and cutting deeper and deeper.
In response to the struggling and twisting of the dying victim, he simply patted the homeless man’s thigh to comfort him, just like he would treat a child who was not obedient during an injection...
...
Jiayi held back the churning in her stomach and gritted her teeth.
She continued to watch the movie professionally until it was finished, and even watched it a second time.
When the murderer cut open the homeless man’s belly alive, it was as if he did not regard him as a creature of the same species. He was so cold and calm that he was not like a human.
The homeless man kept crying and begging for mercy, but he seemed not to hear it at all.
Humans will feel soft-hearted and even sympathize with the sadness even when they hear the cries of other animals, not to mention the weak pleas and cries of their own kind...
[Is it a doctor? 】
The dissection technique was very different from that of forensic doctor Xu. He seemed unfamiliar and confused, like a novice.
But there were fine lines at the corners of his eyes. He didn't look as young as a medical student with little experience. Could he be a pervert who dreamed of becoming a doctor?
After the murderer cut open the victim's stomach, he even used his gloved hands to check inside his stomach.
Was it a performance?
The murderer was also crazy. Tonight he suddenly wanted to play a doctor, so he found a homeless man who had no family and was the easiest to kill?
After Jiayi came out of the distracting image, she bit her lower lip and frowned in thought.
In her opinion, poisoning was not the method he really chose to kill the homeless man. It seemed to be just one of the methods the murderer used to make the victim lose the ability to resist, just like hitting the victim's head with a baseball bat, which was only used to prevent the victim from being disturbed when the murderer performed a "laparotomy".
She unconsciously rubbed her hairline and showed a troubled expression.
Weird behavior is the most difficult to trace to the psychological source. After watching the flow image, Yi Jiayi felt that the doubts in her heart did not decrease, but increased.
Turning to the corner, tearing open a plum candy, Jiayi put it in her mouth. Tasting the sour taste, she was silent for a while before turning back.
"The murderer damaged the victim's abdomen severely, but when I tried to recover, I found that there were deep wounds that could be connected into a line." Xu Junhao pointed to a line running from top to bottom on the victim's abdomen.
"What does this mean?" Liu Jiaming asked with a frown.
"..." Xu Junhao frowned and fell into deep thought.
"The murderer may not have stabbed the victim's abdomen at first. He may have cut open the victim's abdomen from top to bottom like this, and then did some things before slashing and damaging the original wound on the victim's abdomen." Jiayi saw that Xu Junhao seemed to find it difficult to organize his words, so she spoke up to explain.
Sir Xu made his judgment based on professional analysis, so there was a lot of professional information mixed in his brain. He had some ideas, but he needed knowledge to support them. He had to be responsible for every word he said, so he had to be very careful with his words and could not make arbitrary conclusions. But it was even more difficult to express his feelings so that the detectives could understand him immediately.
But Jiayi was different. She did not have the trouble of finding the most appropriate content in the huge amount of information. She just had to say what she saw, so it was easier for her to describe and she was more determined and unhesitating.
Xu Junhao did not know the reason, but he felt that Jiayi was like a soulmate, and a very smart soulmate.
He had just muttered a thread, and she had already figured out his guess.
"Yes, I have this guess." Xu Junhao retracted the finger that was pointing at the wound. He gained a lot of confidence from Jiayi's affirmative words and spoke more smoothly:
"I have carefully analyzed this long knife wound. The technique is not very stable. It is definitely not that of a doctor. The tool used by the murderer is not very sharp, so he did not 'cut' this wound, but 'cut' and 'saw' it."
Xu Junhao imitated a movement of cutting and pulling at the same time, which is more like the movement of ordinary people using a knife to cut meat in the kitchen.
"But from this wound, it can still be seen that his wrist strength is not weak, and the cutting is still quite stable.
"He used his right hand, which should be his dominant hand."
The detectives took notes one by one.
"Judging from the bleeding situation of the wound, the murderer cut this wound while the victim was alive. "Xu Junhao continued to add.
"The murderer is an extremely cold-blooded and cruel person." Fang Zhenyue stared at Xu Junhao and guessed.
Xu Junhao nodded, he agreed with this point. Judging from the injuries suffered by the victim, he should still have the ability to respond to cutting before death, so he would struggle, howl in pain, etc. Even if his mouth was blocked, he would still sob. The murderer did not hesitate when he cut the victim.
If this is not considered cold-blooded and cruel, then he doesn't know what kind of person is considered cold-blooded.
"It seems that there has been no similar deceased before." Sanfu suddenly interrupted. "
First poisoned, then hit the back of the head with a stick, the stomach was cut open, and then damaged by random knives..." Uncle Jiu shook his head, "There is no similar case, at least not in human homicide cases. "
It's possible that this murder was the first time he committed a murder...against a human being." Yi Jiayi frowned and continued.
"It's possible, but it doesn't look like a first offense. "Xu Junhao looked at the tragic state of the corpse and found it difficult to judge. Based on his experience as a forensic officer, the murderer is often filled with fear and panic when killing for the first time, and is bound to make many mistakes and leave many marks on the corpse.
But this murderer's behavior seemed very logical, and looking at the corpse, it would seem that the murderer was not panicked.
"There are no footprints, no fingerprints or murder weapons left behind, and the murderer's skin tissue has not been found on the nails of the corpse... This murderer is either an experienced serial killer, or a terrible guy who is extremely cautious, smart, and has planning and anti-detection capabilities. "Jia Yi continued what Forensic Doctor Xu said.
Xu Junhao nodded, I'm afraid that's the case.
Everyone chatted with Mr. Xu for a while, and then left without disturbing Xu Junhao to carry out further autopsy.
On the way back, the detectives who had discussed it when they came became silent and could not say a word.
Jia Yi followed the team with her small notebook, thinking deeply as she walked.
The victim and the murderer were reflected in the flow image. Apparently, they didn't know each other, but the murderer must have observed this homeless man long ago, and was very familiar with his existence and status. Judging
from the murderer's behavior, he must have figured out the way and planned a "killing plan" for this homeless man.
Whether it was food, baseball bats or knives, and the murderer accurately found the homeless man in Tongzhou Street Park, this can be confirmed.
The question is, who is the murderer?
And why did he kill this homeless man?
Judging from the murderer's behavior, it does not seem to be revenge.
It is very likely that the crime was committed by a stranger, which is what detectives fear the most.
No murder weapon was found;
no witnesses;
the victim was not in the social network...
In the past, most unsolved cases were shelved for this reason. In an era without cameras, this was almost unsolvable.
In particular, the murderer this time wore a hood and a mask. Jiayi did not see his hairstyle and face, only his eyebrows.
The more she thought about it, the more she realized that there were huge missing items in this case.
Taking a deep breath, Jiayi tried to get rid of the grief and continued to dig for inspiration.
So what about thinking from the motive of the murder?
Why did the murderer kill the homeless man? What did he get from the homeless man?
Her eyes lit up again, Jiayi strode back to the office and immediately looked up the information that the B team agents had obtained after their visit yesterday.
"Map!" Jiayi saw the information about the poisoning of wild cats and pet dogs, and turned to Liang Shule who was walking in and said.
"Ah!" Liang Shule responded, turned around and took out the map, unfolded it and handed it to Jiayi.
With a "click", Jiayi took off the pen cap and immediately drew two circles on the map.
One is the street park where the pet dogs were poisoned. It is on the way home from Jiajun's house. It can be reached by taking a short detour. It is in Sham Shui Po near Yau Ma Tei, not far from Yi Ji.
The seaside park where the wild cats were poisoned is on Cherry Street West, at the junction of Sham Shui Po and Yau Ma Tei, not far from Yi Ji.
Jiayi connected the two parks and drew an arrow from right to left. She
also circled the Tung Chau Street Park in the north and drew an arrow from the Seaside Park to the north pointing to Tung Chau Street Park.
The three crime scenes formed a triangle, encircling an area of Sham Shui Po.
"The murderer should be someone who lives in Sham Shui Po. The three parks are not far away. To know that there are wild cats, pet dogs and strays in these three parks, it often takes people who have been to these three parks many times."
Jiayi frowned again, but although the methods all involved poison, she could not be 100% sure that the murderer was one person.
"It's a pity that the bodies of these cats and dogs have already been dealt with."
"But it's very likely that it's the same person." Fang Zhenyue suddenly spoke up, "The murderer couldn't have become a cold-blooded and cold-hearted killer all of a sudden. He must have experienced many deaths in the process of 'growth' to become numb to death. He must have killed many creatures to determine the efficacy of rat poison and accumulated enough experience in both emotions and behavior."
"Then shall we temporarily determine the direction of the investigation to be the same murderer in the three cases?" Jiayi raised her eyebrows.
"For now, this is the only way." Fang Zhenyue gave an affirmative answer. In the absence of clues and directions, such a bold guess is allowed.
"Before these two cases happened, there were reports of a large number of stray cats, pet dogs not on leashes or defecating everywhere."
Jiayi turned over another data sheet:
"The presence of homeless people has affected the normal activities of citizens in the park area, and there have been many complaints and reports..."
Jiayi raised her head and stared at everyone for a while, then walked decisively to the whiteboard and wrote down the next word:
[Bringing trouble to the lives of citizens]
After thinking for a while, she added:
[Punishment]
[Eradication of harm]
"Is it possible that the murderer's motive was like this?" After writing it down, Jiayi stared at the handwriting and turned to ask.
"..." Everyone looked at each other, and no one could give an answer.
In a state of confusion, only Brother Yue and Sister Eleven dared to make such bold speculations.
"Brother Sanfu, take Brother Jiaming to meet the person who was hit on the forehead by a stone thrown by a homeless man." Jiayi pointed to the content mentioned in a certain document, and after Tan Sanfu and Liu Jiaming responded, she added:
"Please try to get a full-body photo of the other party. I want to use the photo to communicate with Sir Xu about this person's height, physique, etc., and study whether the person who was hit by the stone had enough strength to cause those injuries. At the same time, compare our description of the murderer's image of 'cold-blooded' and so on."
"OK, Sister Eleven." Tan Sanfu nodded, pulled on his coat neatly, and took Jiaming with him to set off.
"Uncle Jiu, please take Gary to the street park and ask if anyone had a conflict with the dog owner before the pet dog died. Or see someone sneakily putting meat or other food on the roadside grass in the park." Jiayi said, and added:
"If our guess is correct, then the pet dog in the street park is likely the murderer's first attack.
"Every murderer's first crime must have a trigger. Something stimulated him and made him realize his killing impulse, maybe it was a conflict with the dog owner, maybe he stepped on dog poop, or he might have been bitten or scared by an unleashed pet dog...
" "Uncle Jiu, you must check it in detail.
"Please record the height and other information of those who have had conflicts because of pet dogs. Just like Brother Sanfu and the others, it would be best if there were photos."
"Understood." Uncle Jiu responded, put on his coat, and walked out first.
Jiayi flipped through her notebook. She only had the murderer's height information. He
was half a finger taller than the deceased, about 1.73 meters, not very tall, but there were a lot of men of this height on the streets of Hong Kong.
She had just closed the notebook when Fang Zhenyue raised his hand and said,
"I'll take Ah Le to the Seaside Park to investigate the poisoning of wild cats. I will also try to extract the information of people who have been troubled by wild cats as detailed as possible."
He thought for a while before saying,
"We should be able to accumulate a lot of information tomorrow afternoon, and then we will have a meeting to screen those who were involved in these cases. "
After saying that, he waved to Liang Shule, then went back to his office to pick up his tweed coat and set off in big strides.
All of a sudden, the entire Team B was sent out, leaving Jiayi alone in front of the whiteboard, writing and scribbling, sometimes biting the tip of the pen in deep thought, and sometimes pacing in the office.
...
At this time in Sham Shui Po, a group of people gathered around a mobile fish ball cart outside a building to buy fish balls.
After buying the fish balls, one of the men in a grey casual suit walked to a sheltered place and ate them while looking around leisurely. After swallowing two balls, a man in a suit and tie came over from a distance.
The man eating the fish balls looked at his watch, took out a small notebook from his pocket, and made a note on it.
The man in the suit walked into the fourth building, greeted the old man at the door, and went straight to the elevator. The
man eating the fish balls made another note, then looked around, added the flow of people around, and then put away the notebook and continued eating the fish balls.
The grandmas surrounding the fish ball cart also saw the man in suits who had just walked into Building 4. They all followed the man's gaze unconsciously for a while. When they looked away, they exchanged gossiping glances with each other in tacit understanding, and then gathered together to chat.
They were all very excited, and it was obvious that they were gossiping about the man in suits.
I don't know what special content could make them chat so gustoly.
The man in the shelter ate a box of fish balls, threw the box into the trash can, put his hands in his pockets, and walked away slowly.
He was leisurely, as if he was just a passerby who happened to pass by and bought a box of fish balls.
The wind was a bit strong today. He tightened his windbreaker and squinted his eyes as he walked against the wind. His eyelids wrinkled into many layers, and the wrinkles at the end of his eyes became deeper and longer.
The wind wrapped the words of the grandmothers and blew into the man's ears——
"...It's that man..."
"...He used to drive a car, but later people kept smashing his car windows, so he sold his car..."
He looked back at the mobile fish ball stall, and then scanned the building that the man in the suit had just walked into. He pursed his lips, strode out of the wind, and never looked back.
