The next morning, the murderer's photo, which had been processed by the Public Relations Department using some newly released computer software, was on the headlines of all major newspapers.
The specially processed photo had no background or other content, only the image of a person, like a newspaper clipping made as a child, carefully cut along the outline of the person with scissors.
But the blurred eyebrows and eyes seemed to become clearer. Although people who did not know the murderer would think that most people passing by looked very similar to the murderer after seeing the photo in the newspaper, the police and the media believed that anyone who was with the murderer day and night would definitely recognize him - relatives, colleagues, and neighbors could all become the report.
The detectives of Team B who walked into the office with newspapers were a little confused. Liang Shule arrived early and asked this question first:
"Eleventh sister, even if we receive a report, how can we quickly confirm whether the other party is the murderer?"
Jiayi can definitely recognize the real murderer at a glance, but she is only one person and it is impossible for her to personally meet every reported suspect.
In this era, there are no cameras, no cameras that can take pictures at any time, and no network that can send photos to people far away at any time. The detectives have only seen blurry photos of the murderer, and they also need a set of standards that can help everyone quickly confirm the degree of suspicion of the suspect. The
Forensic Department has already tested the murderer's blood type: type B.
The cloth stained with the murderer's blood has been sent to a specialized department for DNA testing, but these cannot help the detectives quickly identify the murderer - we can't test the blood type and DNA of a person as soon as we see him.
Just when everyone was feeling distressed, Jiayi slapped a stack of documents she had written and sorted on the desk, took off the pen cap with a snap, and wrote on the whiteboard:
[Male]
[Strong, although he looks thin, his upper limb muscles should be very strong, and he should have a lean physique. And the bones of his fingers and wrists should be relatively thick. 】
After finishing this line, she turned around and explained to everyone:
"This fits the profile of the murderer given by the Forensic Department and the Medical Examiner: the murderer swung the baton with great force, the damage wounds were deep and continuous, he had the physical strength to drag the corpse a long distance after killing, and he arranged the scene for the body disposal, but he still didn't look too tired."
She pointed with the tip of her pen to the multiple photos of the murderer on the whiteboard. Each photo showed that the murderer showed no signs of fatigue.
[Age around 40]
Jiayi pointed at the corner of the murderer's eye in the blurry photo:
"I called Rick, a senior forensic chemist who does facial analysis in Central. Although this photo only shows the murderer's eyebrows and eyes, there are actually many clues around the eyes. These wrinkles, drooping eyes, eyelid condition, etc. are all consistent with the characteristics of a 40-year-old male."
In fact, Rick only said that he looked like a middle-aged man. After all, the other party had limited information and the photo was so blurry that even the eyelids could not be seen clearly.
But Jiayi had seen the murderer's facial features clearly. She followed the method that Brother Rick had taught her, looked at countless photos of middle-aged men of various ages, and compared the murderer's facial features in high-definition heart flow images. In fact, she had already compared it to a 43-year-old man who was most similar. However, she wanted to use Brother Rick's name to fool everyone into believing her profile of the murderer's age, so it would be better not to be too detailed or too exaggerated.
"!" Liang Shule copied down what Jiayi wrote on the whiteboard, while showing an expression like Grandma Liu visiting the Grand View Garden.
It turns out that CID's investigation work is so amazing! With the cooperation of the experts from the Forensic Science Division and the Forensic Department, they can rely on such a blurry photo to judge the murderer's age range!
Even the most imaginative murderers probably couldn't have guessed that after being covered up like this, the secret would be revealed to such an extent!
Taking a deep breath, Liang Shule laughed again. The serious crime squad was so powerful, and the police officers who caught the murderer were so powerful, and he was now one of them.
The more powerful they were, the more excited he was!
[The murderer's nails should be neatly trimmed, and he is probably unmarried. He looks gentle, even kind, and calm.]
In the flow image, the murderer did not wear gloves before solving the case, and he did not wear a ring, nor did he have any traces of wearing a ring. Basically, it can be preliminarily guessed that he is unmarried.
Thinking about his movements again, he went out to commit crimes in the middle of the night, and before that he had to spend a lot of time to investigate multiple victims, and he dared to cut off the victims' limbs and take them away without restraint... These details made Jiayi conclude that the murderer's living environment probably did not have a second eye.
Liang Shule just felt proud of being a detective, but suddenly saw Sister Eleven write this line, and he showed a stunned expression.
Huh?
With the help of other expert departments, even the murderer's nails and marital status can be inferred?
He sat up straight, his eyebrows raised to his hairline, and his expression of surprise was beyond words.
When Jiayi turned around and scanned everyone, she saw Liang Shule's exaggerated expression at a glance, and couldn't help laughing and said:
"This is the content of "Criminal Psychology". I talked to expert Tannen last night, and it was actually speculated that the murderer may have certain emotional disorders, such as being naturally indifferent to people and having no empathy, but his IQ is not low. Since childhood, he has shown an excessive interest in cruelly treating small animals and so on. However, these contents cannot be immediately grasped through observation. What we have to do today is to judge through observation as quickly as possible how likely the person reported by the citizens is to be the murderer in the photo, so everyone just look at what I wrote on the whiteboard."
Jiayi avoided the main point by saying "We have also deduced more information about the murderer through criminal psychology, not just what is on the whiteboard." This sentence successfully diverted everyone's attention.
The detectives were all amazed at the mystery of criminal psychology, and completely forgot to delve into the clues such as the case, the murderer's details, and the murderer's blurry photo to deduce the content on the whiteboard.
Jiayi saw that everyone was amazed, shaking their heads or busy taking notes, and no one questioned the reliability of her reasoning. She breathed a sigh of relief and continued to write the following content on the whiteboard, making the detectives miss the best opportunity to question this column of information, reducing the detectives' impulse and tendency to mention this line of content again.
[Height about 172cm]
Liang Shule saw this line and immediately laughed.
He knew how this conclusion was drawn. When he went to meet photographer Zhao Sheng with Uncle Jiu and Sister Shiyi, Sister Shiyi asked him to stand in the same posture as the murderer according to the murderer's standing position shown in the photo, and then ran upstairs to Zhao Sheng's house and observed Liang Shule through the window of the photo.
Based on the reference objects such as houses, walls, trees, etc. that would not change, the height of Liang Shule and the murderer were compared.
The conclusion was that the murderer was one finger shorter than Liang Shule, which was about 172cm.
At that time, Liang Shule thought that Sister Shiyi was very smart for coming up with this idea in the first time, and now he couldn't help but admire Sister Shiyi's wit even more.
He wrote down the height in his notebook and marked the words "Cao Chong weighed an elephant" on the side to quietly praise Yi Jiayi's sharpness. Now
he also looked at Yi Jiayi standing in front of the whiteboard with a silly smile of admiration.
"If you don't match the profiles on the whiteboard, just screen them out. If you meet someone who matches the image on the whiteboard, call me anytime. I will do a preliminary screening first, and then I will decide whether to take them back to the police station for a preliminary briefing. OK?"
Jiayi snapped the pen cap shut, and after saying goodbye, she tapped on the whiteboard with a marker to attract everyone's attention.
"Understood, Eleventh Sister!"
"OK, madam!"
"Got it, Eleventh Sister~"
Everyone stood up one after another, carrying notebooks and papers with the contents of the whiteboard written down, and set out in turn according to the division of Brother Yue, under the assignment of the police operator, to meet the suspicious men reported one by one.
Liu Jiaming was the last one to step out of the office. When he stepped out and in, he suddenly turned his head and smiled, and said loudly:
"Eleventh Sister, you are super sharp!"
After that, he pointed to the stack of documents that Yi Jiayi placed on the office desk. Everyone knew that the reason why Yi Jiayi was able to make such a detailed profile in such a short time after the second murder occurred, with such clear direction and logic, was all due to these.
The detectives saw it with their own eyes and felt more respect in their hearts.
After such a long time together, the team members have already understood that it is not easy for Yi Jiayi to become a detective. She is really amazing.
Jiayi smiled brightly, raised her chin, raised her right fist, and responded with kindness:
"Brother Jiaming, keep going and try to find the murderer!"
"Got it, Sister Eleven~" Liu Jiaming laughed and walked out of the office.
Jiayi just turned around to pick up the documents on the desk, and heard the noises of the three brothers in the corridor:
"You are the only one who can flatter!"
"Why are you so sweet? Let me taste it to see if it's honeyed?"
"Ahhhh... Help..."
"Hahaha..."
"Sister Eleven is awesome!"
"Wonderful, Madam Yi!"
"..." Jiayi's mouth was about to rise to the sky. She hugged the stack of documents and felt that all her efforts were recognized and all her efforts were worth it.
Fang Zhenyue had just spoken to Mr. Guo from the Public Relations Department to confirm the next public opinion support work and the details of guiding the report. When he opened the door, he saw the candy-colored lights flashing in the B team office, which was simply sweet to the heart.
He leaned against the door of the B team office with his arms folded, smiling at Jiayi, who was like a little mole, wanting to laugh but had to bite his lower lip with his teeth to hold back his laughter.
"Madam Yi, I sincerely invite you to go and check the police report files of the past few months~" Fang Zhenyue raised his eyebrows and smiled.
"OK, Mr. Fang!" Jiayi turned around hurriedly, and when she saw that it was Brother Yue, she relaxed her image and smiled like a flower.
…
The screening of the detectives of Team B in the morning was not very smooth. Some of the men who were reported did not look like the photos at all. They could be seen as unreliable at a glance without even comparing them with the profile of Eleventh Sister.
Some people were simply taking this opportunity to settle personal grudges, calling to report that the neighbors who they were not on good terms with were the murderers, and asking the police to catch them.
Those who looked similar did not match the profile of Eleventh Sister. They
were either skinny and had no strong upper limb muscles, or they were too old, or they were married with many children, and some were of different heights, or they were irritable and not peaceful at all...
When we heard Yi Jiayi talk about profiling before, we all thought that even if we screened according to this profile, we would probably still screen out a lot of people who matched it.
Now that I have screened out almost everyone using Yi Jiayi's profile, I finally understand how powerful those profiles are.
Yi Jiayi, who is checking the files with Brother Yue, is trying to find out if there are other reports of poisoning cats and dogs, missing strays, etc. It is a bit predictable that there will be almost no phone calls for reporting and online interrogation.
Many of the characteristics of the murderer are actually contradictory. Thinness must be muscular and strong. Thin and strong people are often working in heavy physical labor. They can't accumulate fat or build exaggerated muscles. There are not many such people in modern society.
What's more, this person also cuts his nails very well, showing that he has considerable requirements for his life and image. How can people who work in heavy physical labor have time to take care of themselves neatly?
If someone lives a comfortable life and works out, they usually won’t let themselves be that thin. Their body fat percentage and muscle percentage are generally more balanced.
Moreover, most of these people are married. People in their forties basically have children, and maybe more than one.
How can such a person have the time to kill people? Even if they are divorced and the children are with their mother, they still have to pay for their upbringing. How can they be so free?
You have to know that it takes time to understand the conditions of three parks and to accurately poison and kill wild cats, pet dogs, and a not-so-stable homeless man.
Many people may not be able to understand the homeless man’s schedule and habits clearly even if they have lived near the park for a few years.
The murderer’s calmness and behavior show that he is very familiar with the situation.
What's more, this is a man who wears a Mao suit and greases his hair even when killing people...
It's not easy to find a needle in a haystack. Jiayi had long thought that it would not be so easy to find the beast, but the lack of good news still made her a little frustrated.
Just when her fingers were rubbed hot and numb from the papers and her eyes were almost blind from screening the reports, Brother Yue suddenly made a new discovery, which greatly boosted Yi Jiayi's morale.
The case has made significant progress again -
one month ago, Miao Liqun himself actually reported to the police that someone was following him.
[He was wearing a beige windbreaker, the same color. He was about the same height as me, a little thinner than me, bald, and his hairline was seriously receding. After I found him, I chased him for a distance and lost him. 】
This is the confession record made by the uniformed police when he reported the case.
Jiayi took the police report handed over by Fang Zhenyue, looked up and looked at Fang Zhenyue after reading it, "The hairstyle is different from the murderer in the photo."
"Maybe he is wearing a wig." Fang Zhenyue guessed.
"..." Jiayi recalled that the murderer's side-parted hair was very fitting and did not look like a wig. "Khaki and beige are very similar, and both are bald. This is basically consistent with the image of the stalker that Liang Shule got from the neighbors. It should be the same person.
"But who is he? Where should we find this person?"
"..." Fang Zhenyue pondered for a few seconds, suddenly raised his head, and pressed his hand on the file. "I have so many informants every month, I can't let them eat enough."
"Ah!" Jiayi suddenly realized, yes, Hong Kong has a large number of informants distributed in various areas, capturing all kinds of useful and useless gossip all day long, and wandering around to see all kinds of people.
Martial artists all know that if you don't understand something, ask the Beggars' Gang!
"Are you interested in going with me to meet the informant? "Fang Zhenyue spoke casually. It was easy for him to say such an invitation and he looked very handsome while speaking.
"Of course!" Jiayi stood up immediately, showing her eager "interest".
"My car or yours?" Fang Zhenyue also stood up, and after covering the file with a pen, he closed it.
"How about rock, paper, scissors?" Jiayi waved her right fist.
"OK. "Fang Zhenyue gladly accepted the challenge.
A few minutes later, Sir Fang bent his long legs and sat in the co-pilot seat of the little car Happy Prince with grievance.
After the 'pilot' good apprentice Yi Jiayi stepped on the accelerator, his back was thrown hard on the seat.
Well, this push back feeling is just right! He is worthy of being the mighty driver he taught!
