"My parents divorced a long time ago. I was brought up by my father. At that time, my father wanted to adopt him, but because he did not meet the requirements, he did not go through the transfer procedures. We grew up together, and later he was admitted to college, and I My father also passed away, so we didn’t have much contact. We just had meals together during the holidays. It was like a family reunion. Two helpless people hugged together for warmth. Later, he dropped out of school, but suddenly became very rich. Two years ago, I stumbled upon his phone and found out that he had been doing that kind of thing…”
Lan An said in a trembling voice: "I sold the house my father left behind and changed it to another one. I used the new house as an excuse to invite him to dinner and take the opportunity to give him medicine..."
At that time, she went to buy a new house and went to a place where no one knew them. She set up a room with good sound insulation and only one small window. She hid all the metal objects in the house, only Left the bed and futon.
She bought a chain, the best lock, a collar, and the chain went through the head of the bed and fastened together.
She has tried and tested the length, she can walk to the bathroom to take a shower and go to the toilet, and she can change clothes and live a normal life.
After locking Song Lanen in the room, she was very careful, even when delivering meals to him, she only used plastic cutlery.
She tried hard to isolate him from all communication with the outside world.
She knew that people like Song Lanen would not choose to call the police, nor could they ask neighbors for help. Once discovered, what he did would be exposed.
There are only electric shavers in the bathroom.
Song Lanen should be very angry, he began to refuse to eat anything.
Lan An and Song Lanen had been in a cold war for a long time. Sometimes in her sleep, she heard the sound of him grinding iron chains, and she couldn't fall asleep for a long time.
In the end, they all seemed relieved, like two roommates living under the same roof.
Before going to work every day, she will leave her meals and changed clothes outside the door. When she comes back from work, she will see the used utensils and changed clothes.
She occasionally leaves a few recent newspapers, and some books.
Sometimes she would sit by the door and ramble about her life, how the painting workshop was doing recently, and how the children were.
But there was no sound from the door, and no response.
Such a life with almost no communication, they lived for two years.
The only time Lan An entered that room was because Song Lanen was ill. Lan An only entered the room after finding that the food had not been moved for two days. Song Lanen's high fever persisted, she was frightened, bought antipyretics, and took care of him for three days.
Only in those three days, they seemed to return to their childhood, back to before everything happened.
Three days later, Song Lanen's fever finally subsided, but Lan An lay on the bedside tiredly and fell asleep. When she woke up, she found Song Lanen looking at her.
He reached out and held her hair, his fingers on her neck.
Just when she thought he was going to kiss him.
He rolled his eyes to look at her, it was definitely not a look full of love, it was a fierce look, like a beast staring at its prey.
She was momentarily frightened.
He gritted his teeth and said to her, "Go away."
She ran out of the room and cried for a long time.
Then, everything went back to the way it was.
After thinking about it, she always felt that it was not safe enough. She was afraid that one day someone would find out what Song Lanen had done. She wanted to help him take the blame. She was also afraid that if she was not there, Song Lanen would starve to death and would be arrested, so she stayed with Liu Yumei. got a key.
Recalling all this, Lan An kept crying.
She is to blame for herself, and a thousand or ten thousand deaths cannot atone for her sins.
Her actions not only let go of the devil Song Lanen, but also killed Liu Yumei.
Maybe at that time, after she drugged him, everything would have been different by calling the police.
Su Hui looked at the files in front of him.
Song Lanen, 27 years old this year, his college major is chemistry, but he was expelled from the school two years later because he failed several exams.
He has learned how to make bombs from Lan An's father Lan Ziwen since he was a child, and then modified and manufactured them according to the chemical knowledge he had learned. He continued to improve the power of bombs and optimize their structure.
He's sociopathic, crazy, and cunning.
He has been providing Xie Qiu with explosives, allowing the man to wander around the city, and a series of fine sand explosions broke out.
This is typical organized indiscriminate killing.
Lan An finally agreed to speak, and Lu Junchi immediately inquired, preparing Song Lan'en's information and photos as soon as possible, and preparing to launch an arrest warrant.
Lu Junchi asked, "Where will Song Lanen go?"
Lan An shook his head: "I don't know. After he dropped out of college, I haven't entered his circle of friends."
While crying, she felt fear in her heart. It was her actions that caused a catastrophe today.
The demon was freed, as if he had been released from Pandora's Box, she thought, he would create a new bombing in the city...
"What about his cell phone and other things?" Lu Junchi asked again.
"I... threw away his mobile phone... The mobile phone card was flushed in the toilet. I confiscated his ID... As his girlfriend, I returned the house he rented." Lan An cried and said, " I thought I cut him off from all contact with the outside world..."
She used to just want this man to live, even if he was locked up for a lifetime, as long as no one knew about his crimes...
"Who is his accomplice?" Lu Junchi asked sharply.
Song Lanen undoubtedly has connections with other people.
"I really don't know. At that time, apart from Xie Qiu, there were some people who were in contact with him. I didn't know those people, but I knew that there were men and women..."
The interrogators changed again, but they could no longer ask the identity of Song Lan'en's accomplices.
Maybe Lan An really doesn't know much about this.
Qiao Ze was full of indignation: "This woman is evil and doesn't know it. It's just too hateful. When I think about the things she did, I feel disgusting. But she is still crying in grievance."
In his opinion, such a person is more difficult to guard against than a real murderer.
Su Hui analyzed: "She fell in love with Song Lanen, not only because of their childhood contact, but I think this woman has a morbid love for serial killers, as well as unrealistic fantasies. She delusionally thinks that her behavior can make him rehabilitate. .In history, there are not a few people who like serial killers, and even some women want to marry serial killers. Psychologists have analyzed this psychology a lot: rescue fantasy, maternal needs, substitution fantasy, etc... "
However, due to the small number of people and the lack of research cases, the specific psychological reasons for this behavior are still difficult to characterize.
Investigative reporter Sheila Isenberg, who wrote a book called "Women Who Loved Murderers," wrote: "These women were romantically involved with murderers in a way meet their needs.”
What Lan An did to Song Lanen, trying to cover up her top crimes, was not out of public safety concerns, but just for her personal satisfaction and self-motivation.
Lu Junchi agreed: "If she did such a thing, the law will punish her..."
Then they asked some pieces of information from Dong Anchen.
It was he who gave Song Lanen the sand from the small window, and Song Lanen gave him the two bombs, telling him to do so, Yu Keke's problem could be solved.
After the incident, Song Lanen asked Dong Anchen, who was frightened and scared, to push everything on Lan An.
It seems that not only ordinary people can't understand her behavior, but also serial killers may not appreciate it.
When Lu Junchi came out of the observation room, he saw Su Hui standing alone in front of the whiteboard in the conference room. This whiteboard was left by Xing Yunhai and had his handwriting on it.
There was only one light on in the conference room, and it was a little dim, which made his back very thin.
Lu Junchi couldn't help but walked over and looked at his handsome profile.
Su Hui squinted his eyes and turned around, confirming that the person who came was Lu Junchi, and turned his head again.
They learned about Xisha's true identity today, and the case has made great progress, but no one is happy. When they caught Lan An and found Xisha's true identity, the pervert also recovered his freedom at the same time.
As long as they think that such a terrifying and dangerous man is still wandering in the city, their hearts have been tugging.
Lu Jun regretted that he had to sleep all the time, as long as Song Lanen could be arrested and brought to justice as soon as possible.
Su Hui looked at the whiteboard covered with clues, blinked his eyes and said, "The murderer deliberately disguised the scene and dropped other people's cigarette butts and hair to mislead the police. This kind of behavior is called setting, and the black market engages in this. The person who does this kind of work is called a set designer. Two years ago, I used to think that the presence of a set designer might affect our judgment. But now, I gradually think about some things, and our thinking at the time may be wrong. …”
In the past two years, Su Hui's memory was vague and chaotic, but as he returned to work, his memory gradually recovered.
Today, he is trying non-stop to recover the case.
Two years later, although he has experienced those setbacks, he has become more meticulous and calm. There have also been some changes in the angle and way he considers the problem.
The bombing case is different from many cases. Fingerprints are rarely found in such cases, footprints are difficult to find, and monitoring equipment is easily damaged. The evidence of the people investigating the case is very sparse, and it is difficult to catch the murderer.
This kind of bomb in the fine sand case is homemade and has obvious traces of manufacture. Every crime scene leaves the same fine sand, similar installation methods, and similar delivery times. There are many points of connection between the cases, proving that these cases are related. Some sporadic blurry images show that the killer acted alone.
The raw materials and production of bombs are not within the grasp of ordinary people.
This type of murder is generally extremely secretive, and in many cases, even close relatives do not understand.
When the Xisha case happened, in front of many side evidences, they logically believed that the murderer was a withdrawn, far away from the crowd, and had anti-social tendencies. The result of this profile also made them believe that the murderer acted alone.
They mistakenly believe that the murderer is the maker as well as the deliverer.
Under such a premise, they cannot explain and restore the case.
Ordinary bombers have their own unique behaviors, but this fine sand, in the follow-up crime, showed a variety of different behaviors, like an extremely cunning fox who is good at camouflage.
His criminal methods are also varied. He just wounded several people in the downtown area, and found traces of the explosion outside the wilderness.
There is no criminal motive, no criminal target, no criminal planning, except that every ten days, a bomb must be dropped in the city to disturb people's good life.
The police are under enormous pressure, and Su Hui and Yueguang have a disagreement over the profile.
Two years later, during the process of interrogating Lan An, Su Hui reviewed all this.
After he changed his mind, the problem seemed to have finally found a breakthrough.
I do not know the true face of Mount Lu, only because I am in this mountain.
Back then, he and Yueguang had no doubts about the fact that there was only one murderer, but thought that the various intricate states that followed were the other's disguise.
But perhaps, only one murderer is the biggest misleading the other party gave them. And other unreasonable things are left undisguised.
What they think is the wrong answer is the right answer.
Su Hui briefly mentioned here and raised his head, Junxiu's face was slightly pale: "Moonlight and I may have been right back then, Xisha was not a bomber, Song Lanen was a weapons engineer. These bombs were made by one person, but They were dropped by different people, and the leader was Xie Qiu. Those who dropped the bombs were a small group. Every ten days, one person in the group would receive a bomb and complete the drop. , showing a variety of different profiling results."
Lu Junchi frowned and thought for a moment, then nodded in agreement.
Once it is overturned that there is only one perpetrator, the precondition that the poster is the producer will make people suddenly enlightened.
Su Hui continued: "Multiple murderers, this is a more effective way to disrupt the police's sight and investigation than the set. There may have been multiple droppers at that time, and they would hold the same bomb and go their own way in the city. put it out."
Historically, this kind of cooperative division of labor has been too rare.
This mode is like a group of players squatting and guarding the game mission.
Every ten days, a new bomb will be produced, and they will draw lots or choose, let a person bring the bomb, and then place it in a place according to their choice, according to their own preferences.
Those who receive the task will walk around the city and finally commit the crime.
So their tools and timing have some commonalities, but because those people are placed differently, they choose different targets, and they show different crime patterns.
Their profilers were led into a maze by this way of murder.
Explained that way, everything makes sense.
Lu Junchi lowered his head and pondered for a moment. Su Hui's inference sounded surprising, but when he thought about it carefully, he felt that it was very likely to be true. What he said was a hypothesis, so he needed to find actual evidence to prove it. at this point.
"There is a murderer in it, who is cruel by nature. He will deliberately choose iconic buildings and place bombs in places with many people. Another murderer, who has a trace of humanity, will avoid pregnant women and children when placing them. Back then, I just caught I met one of the posters. That day, I happened to meet Xue Qiu…”
Having said this, Su Hui lowered his head and said, "The police have not caught the weapons division and others, so before this case was not really solved."
Now, with the return of Song Lanen, the core of this organization has also returned.
Lu Junchi sorted out his thoughts: "Do you think they will commit the crime again soon?"
Su Hui nodded: "They may have hoarded a lot of materials. Including the time for making bombs and preparations, we may have about two days..."
With the arrest of Song Lanen and the actions of the police, these people will immediately know that they are already under arrest.
Huadu has been completely blocked and strictly investigated, he can't escape if he wants to.
It's a race of good and evil.
It's about a human life.
Su Hui pursed his lips and coughed a few times, then stated his conjecture: "The worst outcome... Song Lanen has been silent for two years and has been suffocated for two years. This time, they may act together with many people, intending to cause even greater damage. casualties."
It's going to be a frantic final hunt.
Listening to Su Hui's remarks, Lu Junchi's fingertips initially filled with a coolness, what kind of unimaginable evil could it take to turn into such a shape, but then blood welled up in his chest.
In the face of such an enemy, he wants to solve the case as soon as possible.
They must stop this catastrophe.
Lu Jun said lately, "What do you think, why do these people do such a thing?"
Only by studying their criminal motives can we effectively find their criminal targets.
Su Hui said: "I haven't figured it out yet. This organization is both a group and an individual. The time and purpose will change with the group's thinking, and the will and ideas of individuals will be mixed in it and become variables. ."
The purpose of those murderers must be more than just revenge on society.
"Can you judge how many people were involved in this."
Su Hui's thinking has never been so clear as at this time. Two years ago, he and Yueguang had their own opinions, and there were still a few cases that could not be included in them. He said solemnly: "There may be four murderers, except for Xie Qiu, there are three others."
At that time, he caught Xie Qiu, who had committed the most crimes. Moonlight might have locked a murderer, and the other two were still hiding in the darkness.
After two years, those scattered sands are finally connected...
Lu Jun said lately: "I understand, I will tell the leader, make all preparations, don't be too hard, let's go have something to eat."
Su Hui understands that haste is not enough, this is a protracted battle that may last a few days, and he cannot fall on the way.
He thought about it and said, "Let's have dinner first, but at night, I want to go somewhere." He paused, raised his head and asked Lu Junchi, "Can you go with me?"
Lu Junchi asked, "Is it related to the case?"
If it is normal, non-working hours, he can accompany Su Hui as long as possible, but now that they are pressed for time, he must calculate the time accurately.
Lu Junchi knew about Su Hui. He lived in a terrible house. He had no family and no other friends. Except for the general bureau, the scene, and the school, he generally didn't like to wander around. And now that Song Lanen's identity has just been revealed, his thoughts are all on the case.
What he brought up at this time must be a very important thing.
Su Hui's eyes drooped down: "It's related, I want to find someone..."
Lu Junchi asked again, "Is it someone I know?"
Su Hui nodded: "You know it, right? It's an old friend of mine, and he is the one who might speed us up to decipher the truth in this situation. The code name he used to use was Moonlight."
