Su Hui tried to concentrate his energy.
Criminal psychology profiling is not metaphysics, but careful analysis and reasoning based on the facts of the case and the characteristics of criminals.
He overturned various conclusions of the fine sand case made in the past, and started to infer according to the latest new clues and ideas.
Bombs are completely different from normal methods of murder.
Since Nobel invented yellow dynamite, it has been used more in warfare than blasting.
Then, the bomber came into being.
This is one of the most dangerous criminals in the world.
The production cost of the murder weapon is very high, and most people will not make it, but at the same time, it is powerful and easier to operate, making it hard to guard against.
In Su Hui's view, the bomber was a rational lunatic.
Their madness has a certain logic, but it has no bottom line.
Compared to the average criminal, the bomber is more unpredictable.
Such a person is more terrifying than an ordinary murderer with a gun in his hand.
There are many representative figures among the bombers, such as the high-IQ Hildo. It took seventeen years for the police to arrest him. He threatened the New York Times with a manifesto titled "Industrial Society and Its Future," arguing that "industrialized humans will eventually be replaced by highly intelligent robots, or ruled by those elites who control robots, and human beings may be will be extinct."
And McVeigh, who killed 168 people, created the Oklahoma bombing. He fantasized about being a hero who would fight ferocious beasts, believing that some humans who served the beasts should be reduced to ashes. He had no regrets for his actions until he was executed.
Most of these murderers have some God complex, that is, God Complex, they think they are powerful, omnipotent, like gods.
They are indifferent and contempt for mortals, believing that they can dominate the lives of others at will. They are arrogant, power-loving, manipulative, and often narcissistic.
These profiles are in line with Song Lan'en's data.
Two years ago, the Xisha case lasted for more than five months, with a total of 15 explosions. Huadu was too big, not every time it would cause casualties, but it made everyone feel anxious and fearful all the time.
It was a nightmare that lasted for 150 days, and the Huadu police have been under enormous pressure.
Su Hui sorted out all the cases of fine sand, except those that could be clearly found to be done by Xie Qiu, and then used the numbers to distinguish them in detail.
In addition to Xie Qiu's six crimes, there are nine more.
He remembered that the other person was locked by the moonlight that year. The point of contention between the two of them was that Xie Qiu and the murderer had different criminal patterns.
Compared with Xie Qiu, this person is more ruthless and full of more variables. The explosions he manipulated occurred earlier, usually in places with a lot of people, mostly in open areas.
The place he chose was a landmark building in Huadu. The first bomb he planted was by the fountain in a very famous square in Huadu, causing damage to the fountain and casualties.
The second time, he caused the collapse of a statue, killing several more.
The third time was at the intersection of the most prosperous commercial street in Huadu, under the electronic screen.
This figure is like a spectator. When the explosion occurred, he may have been hidden in the crowd, watching everything indifferently, but his heart was extremely excited.
Among several people, his desire to perform and to manipulate is the strongest.
Before, he did not commit many crimes, only committed these three crimes.
He loves killing and is the most brutal among them. He and Xie Qiu, who destroyed happiness, set a distinct style for the Xisha case.
The second murderer, in several explosions, the murderer spent a long time, and most of the destinations he chose were indoors.
He would carefully place the bomb, hide it, and detonate it after he had left completely.
Once he was in a locker without a camera, and once in an activity room at an event center.
Rather than killing people, he prefers to destroy, to destroy those buildings, to cause people's commotion, panic, and chain reactions.
Compared with the last murderer, he was even more timid and looked ahead.
He may have some mobility issues, so while he was holding the bomb, it was the last to detonate.
He has opened the locker, and he may have some stealing skills. When there are empty boxes around, he chose the middle box, which may not be tall.
Su Hui judged that this person is a male, he may be a former criminal, he has some sense of hatred for the rich, and the areas where he is placed are the so-called rich areas.
He will probably be the oldest of several. In the past cases, he committed the crime only two times.
The third murderer, Su Hui still remembers, Lan An said something that Song Lanen knew, there were men and women, and he judged that this person might be a female suspect.
The murderer may have committed four crimes, but two of them were empty, one bomb exploded in a garbage dump, and the other exploded outside the botanical garden.
At the time in the botanical garden, it was raining lightly, and she might be carrying an umbrella, which made it inconvenient for her to move.
She deliberately avoided young children and pregnant women when the bomb detonated.
In comparison, the murderer had the least impact. No one died because of her actions, and only a few people were injured. It seems that she has not completely dehumanized her.
Su Hui can feel that this woman is not a little girl who just came out of society. She should be over 30 years old. She may have had children, or she may have experienced the pain of bereavement. She is inflicting her own pain on others. .
She's not pretty, she's very mediocre, so in the crowd, she can't attract people's attention.
These people all got the dangerous goods from Song Lanen. Under what circumstances and where will they meet
Is it on the street or under a bridge? Will Song Lanen give the bag to them or will it be put in a place and wait for them to come and pick it up
Have they ever met, or are they meeting for the first time now
What means of transportation will they use
The subway security check is strict and can be ruled out.
He focused on bicycles, walking, private cars, taxis.
There is also the time for activities, he can probably calculate that the time when these people get those things is in the afternoon.
Two years ago, these people committed multiple crimes.
They evolved over time, and slowly, they found that it seemed that the game could be more thrilling.
I can easily escape the law without being discovered.
I expected a more brutal killing.
They have already eaten the marrow and know the taste. Under such a mentality, repeated serial explosions may have happened.
With more information now, Su Hui completely analyzed the Xisha case. At 3:30 in the morning, he finally finished writing and let out a long sigh of relief.
Such three people may be the masterminds and murderers they have to face.
But there are still some that Su Hui couldn't figure out. How did these three people get together with Song Lanen
What do they have in common
How do they get in touch, and why do they do such a thing
Are they enjoying it? Or as a belief
For the past two years, Song Lanen has been imprisoned, so what are these three people doing
Do you live in hiding among human beings like ordinary people
Does Song Lanen's escape have something to do with them
There are still too many questions to answer, but Su Hui felt a little cold, his hands were shaking a little, and the wound on his chest was a little painful. This level of pain is still within his tolerable range, it just makes him unable to concentrate on thinking.
Holding the printed profile, he felt dizzy as soon as he stood up.
It seems that it has been supported to the limit, the legs are weak, and the eyes are black.
Lu Junchi had been watching the computer at the dining table, and when he saw him get up, he hurried over and just happened to support him.
Only then did Su Hui stand firm, and handed him the profile results: "There may be inaccuracies, now... I can only do this first, and I will continue to deduce it tomorrow. You should use this as a reference first, don't give others see."
Lu Junchi took the test and writing results, which was a thick stack, and every word was stained with effort.
Su Hui summarized the above information in a low voice and briefly described it to Lu Junchi, and then Su Hui said: "These are just profiles based on the information from the past two years ago, these people should be the core of this crime. But I I suspect that if they collect enough production materials, Song Lanen may expand the game."
Lu Junchi frowned and asked, "How to expand?"
Su replied: "The easiest way is to contact potential murderers and find more people to join in."
Now that they have deduced that many serial killers are connected, they may find more people to participate in such a spree.
Lu Junchi asked: "How can he confirm that the newly recruited person will deliver? How can he confirm that those people will not report him to the police?"
When a novice enters, the uncertainty factor will increase, and for those criminals, the risk factor will also increase.
Su Hui shook his head: "He doesn't need confirmation, he only needs those people to join in. The information is input by him unilaterally, and the other party doesn't know much about the situation. The more people enter the game, the more dispersed the police force will be. the better the odds.”
Things are not so easy to solve right now.
Having said that, Su Hui coughed repeatedly.
Lu Junchi touched his forehead with his hand: "You have a fever." Looking at Su Hui like this, he felt that he was working too hard, and he felt sorry for him.
"It's not that serious..." Su Hui's cold sweat kept breaking out, his heart beat faster, and he was too sleepy to open his eyes, but he pulled his hand away and murmured, "Pour me some hot water."
Lu Junchi stretched out his hand to hug Su Hui, but Su Hui didn't let him hug him. He leaned against the wall and walked slowly into the bedroom, sitting on the bed.
When Lu Jun went out late, Su Hui opened the cabinet, took out a few pills, poured them into his hand, and put them in his mouth.
Several medications are available to reduce fever, relieve pain, and stop bleeding.
He couldn't distinguish the symptoms and didn't have time to study it in detail. He just hoped that he wouldn't be dragged down by his body to be unable to move at this time.
This case is too critical, he doesn't want to miss a cent, let alone fall.
When Lu Jun brought hot water over, Su Hui took a few sips of water and swallowed the medicine. He lay on the bed and said to Lu Junchi, "I'm a little sleepy."
"Go to sleep, I'll sleep for a while, too." Lu Junchi lay beside him and dimmed the light, "I'll accompany you."
Su Hui's head was still a little dizzy. He curled up and held on until the medicine finally came up. His consciousness became hazy, and he finally entered a state of half asleep and half awake.
Lu Jun didn't sleep for a while. He looked at the profile results written by Su Hui. After a while, Su Hui's breathing calmed down, and he reached out and touched his forehead.
There was a thin layer of sweat on it, but the temperature seemed to have dropped a little, so he was a little relieved.
Su Hui seemed to feel something, his eyes were closed, his eyelashes trembled slightly, he turned sideways and curled up in his direction.
Lu Junchi stretched out his hand and patted him on the back like he was coaxing a child.
The city at four in the morning was extremely quiet. After he read Su Hui's profile, the appearance of these people gradually became clear in his mind.
Those murderers are like ordinary people, living with them in this city.
Lu Junchi thought about it, such three people, plus Song Lanen who had just escaped, would be very conspicuous.
They are not low-key and forbidding people who will act in secret.
Thinking of this, he opened his eyes and turned on his mobile phone. He left a message for the rest of the work group, and asked them to send Song Lan'en's photo and wanted information to various sub-bureaus as soon as they went to work tomorrow. Find out if he goes to some public places.
He thought about it and added a few screening criteria. According to Lan An's confession, Song Lanen had long hair. He might have cut his hair or wore a hat.
After all this was done, Lu Jun turned around and fell asleep.
Su Hui didn't sleep well that night. He always felt that the time was up, but he wanted to open his eyes but couldn't open them at all.
It seemed that someone was talking beside his ear, and it was like a strange sound, which made him unable to hear what it was.
When he frowned and opened his eyes, the sky was already bright.
Su Hui looked at his watch, it was already past eight o'clock.
He wondered if Lu Jun didn't wake him up because he saw that he was sleeping too fast...
Then he saw Lu Junchi come in: "I have already made arrangements for them in the morning, and they all went to the field to inquire. At nine o'clock, Bureau Zou said that there would be a middle-level meeting. I saw that it was too late, so I didn't call you."
When Su Hui got up, he was still a little top-heavy, his chest was stuffy and a little dull, but he was much better than the early morning this morning. He coughed a few times and hurriedly washed up.
Lu Junchi picked up a phone call when he was in the car, hung up and said to him: "This morning, the various branches have already been conducting investigations, and now they have found a barbecue restaurant where Song Lanen and a few people dined last night, Laoqu and the others have already enrolled with the owner. Confessions, and call for surveillance."
Lu Jun paused for a while and then said, "The restaurant owner's description of those people basically matches your profile."
With witnesses and images, in this way, the few people who were with Song Lanen should be able to find them soon, and they could also get more information soon.
Su Hui finally breathed a sigh of relief. This time, they must run in front of each other.
When he was about to get to the branch, Lu Junchi answered another phone call, and after a few ok, his expression became a little serious.
After he hung up, Su Hui asked, "What's the matter?"
Lu Junchi frowned and said, "Secretary Wang from the General Bureau called, saying that Bureau Zou asked him to notify you to attend the middle-level meeting this morning."
The last time he had contact with the Zou Bureau, he was a new leader who was not easy to speak. Now that the case was at the most critical moment, he did not know why the Zou Bureau suddenly proposed to let Su Hui participate in the meeting. Lu Junchi felt a little strange, and also had an ominous premonition. It seems that today's middle-level meeting will be a feast of Hongmen.
Su Hui was indifferent, pressing his hand down and saying, "Maybe it's about the case, it won't be a problem."
