Breaking away from the flow image, Jiayi quickly took up her pen to write down the details before she forgot them.
The traditional Chinese characters with a lot of strokes were written by her in a flamboyant style. In order to be quick,
she did not care about being neat. The murderer was indeed short and thin.
He was not particularly ugly, and his appearance did not seem to have any flaws that would make women hate him.
On the contrary, he looked very... simple. With a broad forehead, thick eyebrows, a broad nose and thick lips, his ordinary appearance would be invisible in a crowd, but his downward-slanting eyebrows and habitual expression made him look like a bitter face. In addition, he was a bit older and had a lot of wrinkles
on his face. He looked like an honest man who had been farming in the countryside all his life and was taciturn but hardworking. When he raised his head and looked over, he didn't look murderous or sinister. Instead, he seemed to have a rough life story that he wanted to tell.
After marking his facial features, Jiayi turned around and asked Xu Junhao about the height of the deceased girl.
"156cm." Xu Junhao said, and couldn't help frowning when he finished speaking.
If someone else asked, he might think it might be a casual question, but if Jiayi asked, it would probably have a deep meaning.
Is there a way to infer the murderer's information from the height of the victim?
The victim was lying down when he died, so there is no way to judge the murderer's height based on the location and angle of the wound.
Is it possible...?
Because of his trust and admiration for Jiayi, Xu Junhao began to doubt his own professional ability.
Jiayi was indeed estimating the height of the murderer, but she did not rely on science.
She suppressed her disgust. She once again immersed herself in the mind flow image of the deceased girl, forcing herself to watch the process of the murderer injuring the deceased, and constantly comparing the murderer's height.
Until one of his static movements made Jiayi roughly determine that the murderer was about one fist taller than the deceased, she immediately closed her eyes and stopped everything in the mind flow image.
The height difference of the girl's fist width is about 1.63 meters.
The murderer once stood in the bright kitchen, standing very straight. If he went to the crime scene, he should be able to confirm this height data again.
After recording the height and appearance characteristics in the notebook, Jiayi was about to leave.
Xu Junhao hurriedly stopped her and asked, "So, why do you ask the height of the victim?"
Jiayi was stunned, her eyes flickered, and then she answered:
"I want to sort out the heights of all the victims who were raped to see if the murderer has a clear preference for the appearance of the victims."
"Oh, I see. If so, then these people can pay special attention. Other citizens can live a normal life without having to worry about becoming the next target of the serial killer." Xu Junhao nodded, looking cheerful after solving the mystery.
Jiayi rubbed her head, said goodbye to Xu Sir, and hurriedly left with Fang Zhenyue.
It was really embarrassing to lie to people, especially when Xu Sir seemed to be so easy to lie to.
…
Back in the B team office, Jiayi looked at numerous photos of middle-aged men on the computer according to the method of judging age that Rick, a forensic officer in Central, had taught her.
Half an hour later, she judged that the murderer's age was closest to the appearance of around 45 years old.
After writing the number '45' on the notebook, Jiayi recalled the murderer's appearance for a long time:
when his expression was relaxed, the wrinkles were ironed flat, and the skin originally hidden by the wrinkles was white.
When people make expressions, skin wrinkles will be generated, and the skin between these wrinkles is squeezed together and cannot be exposed to the sun. Over time, the skin outside the wrinkles will be tanned, leaving light-colored wrinkles in the original skin color inside the wrinkles.
In other words, the murderer had been exposed to the sun for a long time.
Sun exposure will cause people to look older than they originally are, so he is likely younger than 45 years old.
In other words, around 40 years old.
After updating the age information in the notebook, Jiayi added the content mentioned in the previous meeting.
(a) Did anyone lose a bicycle between Tai Po and Ma On Shan? What kind of bicycle was it? Did anyone see the appearance of the thief at that time? Publish photos of bicycles (similar styles, colors, and age) in newspapers, and ask citizens to help report. If there are suspicious people riding such bicycles recently, please call the police immediately.
After writing the first question that needs to be clarified, Jiayi closed her eyes and continued to recall.
1. The murderer's palms and fingers have thick cords. When he was stroking the baby, he made the baby uncomfortable. After withdrawing his hand, there was a movement of stroking the cords.
Jiayi noticed at the time that the man had thick cords on the palms, bases, hukou, and palms of his fingers.
And his nails were very thick, and many of them were deformed, like a yellowed stone embedded in the fingers.
2. The murderer has many wrinkles on his face and his skin is very dark, but the skin inside the folds is white, which shows that he is exposed to the sun every day. This may be related to his job.
[Judging from the nails, facial features, and expression, is it possible that the murderer was a farmer before?]
If the murderer really escaped from the mainland as the New Territories North Serious Crime Unit speculated, and his first stop was Sheung Shui, then he may have fled from Luohu District in Shenzhen, because Sheung Shui is just below Luohu District.
Therefore, the murderer is very likely a Cantonese.
Thinking of this, Jiayi wrote down the second thing that she needed the task force to confirm in her notebook:
(ii) Contact the mainland police to inquire whether there is a criminal escape near Luohu District.
Most likely he is a farmer, about 1.63 meters tall, about 40 years old, with hair about one finger long and dark skin.
But how can we prove that the murderer is such a person?
Of course, it would be best if the murderer was seen stealing a bicycle, and then find an artist to draw a portrait for the witness.
But if there is no eyewitness...
well... you can ask the forensic officer. Based on the severity of the wound, it should be able to prove that the murderer is very strong, at least it can be roughly inferred that the murderer is a male who does physical work.
As for height, it is a bit troublesome. The forensic colleagues inferred that the murderer was about 1.7 meters tall based on the murderer's footprints, because the murderer has an unusually large pair of feet.
On this basis, it is very difficult to refute the argument of the forensic department.
After all, it was not just the colleagues in the New Territories North Forensic Investigation Division who came to this conclusion. Brother Da Guangming also calculated a height of 1.7 meters. The formula used by the Forensic Science Division to determine height based on footprints is the same.
This algorithm does not exclude special cases, but to prove that this murderer happens to be a special case, other ideas and methods must be used.
Jiayi couldn't help scratching her hair.
After thinking for a long time, she wrote and drew on the notebook, sometimes recording, sometimes crossing out, and was very distressed.
After putting down the second question, Jiayi continued to think.
If the murderer would use the things he took from the previous person's house to go to the next house, then if all the things he had taken were listed and analyzed where he would go to use these things, would there be a chance to catch the murderer?
For example, if the murderer took the money, could we then go to the victim’s home to check for places where people could spend money to buy food?
But this would be too much to check, and without a clear description or portrait of the murderer, even people who have seen the murderer might not be able to confirm it…
Jiayi picked up her pen and wrote down the third thing to do in her notebook:
(iii) Collect and find all the things the murderer took from the victim’s home, and use this to infer:
A. Where the murderer might appear after the murder to use those things;
B. Whether the murderer took any clothes, then what color and what did the clothes look like, so as
to identify the murderer. This can be determined by the forensic colleagues based on the trace examination of the crime scene and the testimonies of the victims’ relatives, friends, and neighbors.
If these two methods cannot make up for the things taken by the murderer, or cannot confirm whether the things were really taken by the murderer,
Jiayi can also guide the colleagues in the forensic department to conduct targeted and targeted investigations based on the flow images. With her guidance, it should be possible to make up for some of the things taken by the murderer.
Looking up, Jiayi saw that Brother Yue was introducing the case to everyone in the team and distributing copies of the materials to everyone to read and familiarize themselves with.
She stood up and said, "Brother Yue, let's go to the crime scene."
"Okay, I'll call Chen Guangyao and ask him to go with us." Fang Zhenyue said and walked to the desk to make a call. While waiting for the call to be connected, he instructed Sanfu:
"Take everyone to sort out the case, list the important information on the whiteboard, and wait for us to come back."
"Yes, sir." Sanfu responded and immediately lowered his head to think about which document to start sorting out and how to arrange everyone to discuss while reading the documents.
Fang Zhenyue's phone call was connected, and he made an appointment and set off immediately.
Jiayi took her notebook, Chen Guangyao took his on-site investigation tool box, and Fang Zhenyue drove his aircraft jeep and stepped on the accelerator to Shek Kip Mei.
The shacks that were once full of familiar faces have long been transformed into pigeon-cage-like public housing blocks. Areas that could only accommodate a few hundred people can now accommodate tens of thousands.
The outward radiation has absorbed a large number of citizens working in Sham Shui Po, Mong Kok and other places. The population flow is large, causing the originally simple population area to become a mixed bag.
When Brother Yue parked the car, Jiayi's mobile phone on her waist suddenly started playing music, which scared her.
In her previous life, she carried a mobile phone every day, and when she first came here, she was not used to life without a mobile phone. Now she is used to having only a pager on her waist, but suddenly she changed to a mobile phone, and she is not used to it...
People are really creatures who know how to adapt to the environment.
"Hello?" Jiayi answered the phone and paused as she was about to get out of the car.
"Yi Shazhan, I'm Inspector of New Territories North Serious Crime Unit B, and also the leader of Team 1 of the Family Bombing Case Task Force, Wang Jiewang." Sir Wang was afraid that Jiayi would not remember who he was, so he introduced himself for a long time.
Jiayi couldn't help laughing when she heard such a long prefix, "Hello Sir Wang, have you found out the result of the stolen bicycle?"
"Yes, your guess is probably right. The neighbors who lived a few hundred meters south of the victim's house in Tai Po Family Bombing Case reported the theft of a bicycle the day after the incident. The murderer probably did not leave after killing the victim, but hid near the victim's house. After seeing us police arrive at the scene, he took advantage of the chaos to steal the bicycle and left." Wang Jiewang said in frustration, they are always one step slower than the murderer.
It was really unpleasant to feel that the murderer was in the open and they were in the dark.
"Do you have a photo of the bicycle?" Jiayi couldn't help asking.
"No, I don't have one." Wang Jiewang thought for a moment and said, "It was a black men's Phoenix brand bicycle, a Shanghai bicycle stolen from Guangdong. The bell was stolen not long after it was bought. Also, because the original seat was broken, the owner replaced it with the back seat of a large 28-inch bicycle and continued to use it... By the way, the seat was brown."
"Did anyone see the thief when the bicycle was stolen? Or has anyone seen someone riding such a bicycle on the road?" Jiayi immediately raised her eyebrows and raised her voice a lot.
"I'll send someone to investigate and see if we can find any witnesses who have seen the murderer. We'll notify you as soon as we have any news."
"Also, Mr. Wang, can you find someone to draw this bicycle, or if there is anyone else who owns such a bicycle, take a photo, and ask colleagues in the public relations department to place an advertisement in the newspaper, offering a reward for the search for this stolen bicycle?" As the call was coming to an end, Jiayi finally jumped out of the car, slamming the door shut while talking on the phone.
"No problem." Wang Jiewang thought about it and readily agreed.
"Thank you, Mr. Wang." Jiayi smiled.
"You should be thanked more. Your idea is right. No wonder you made such a splash at the year-end commendation ceremony last year." Wang Jiewang laughed.
Then, Jiayi heard someone whispering to Wang Jiewang through the receiver: "Boss, don't say that, as if you are jealous of Yi Shazhan's success last year. The word 'stood out in the spotlight' is not a compliment..."
Wang Jiewang's laughter choked when he heard this whispered reminder on the phone.
Although Jiayi couldn't see the other person's face, she could imagine Wang Jiewang's embarrassed expression with a blushing face, and hurriedly said with a smile:
"I'm just guessing. Sir Wang handled the matter so quickly and made progress so quickly, that's really amazing."
"No, no, you're still amazing, haha, hehe..." Wang Jiewang scratched his ears and cheeks, and was too clumsy to say anything more. After boasting, he just smiled awkwardly.
"Okay, I wish Sir Wang all the best in the future. I'm going to do my job too." Jiayi said goodbye to Wang Jiewang with a smile, and finally ended Sir Wang's confusion and embarrassment.
Turning back, she saw Fang Zhenyue standing a few steps away, frowning and looking around at the streets and buildings. Da Guangming also stood beside Brother Yue, looking around like Brother Yue.
Jiayi hurriedly strode to the two of them, patted Brother Yue's shoulder with her left hand, and patted Brother Da Guangming's shoulder with her right hand. When the two turned around at the same time, she said cheerfully:
"Let's go!"
