When she called Ji Bai, Xu Xu had already taken a taxi to the police station. The sky was dark and the air was clear. It was as if her whole body was shrouded in a gloomy chill. She walked up the stairs of the police station and saw Ji Bai from afar with a phone in his hand.
"Let's talk inside." Ji Bai looked at her frail but energetic figure and felt a little sorry for her, so he pulled her into his arms.
Now, all the criminal police officers in Lin City were out on patrol. Ji Bai returned to the office to report the progress to the station chief, but the station chief was catching up on sleep in his room. The big office of the Criminal Police Unit was empty. Ji Bai took Xu Xu's hand and sat on the sofa. He poured her a glass of hot water and held her hand. "Tell me."
Xu Xu was not as experienced as Ji Bai when it came to solving cases. Especially when it came to the most critical crime scene investigation, Ji Bai was more sensitive and logical than her. However, there were very few traces left at the crime scene and the murderer committed the crime at random. At this time, normal criminal investigation methods were at a bottleneck, but Xu Xu's psychological reasoning was not affected.
Xu Xu nodded and said, "These few days, I've been imagining myself as a psychopathic killer. I tried to figure out his psychology and had some in-depth thoughts …"
When she said this, Ji Bai could not help but look at her, then his gaze naturally fell on her stomach. However, she did not care. She took a pen and a piece of paper and quickly wrote and drew as she spoke.
"First of all, a major change must have happened to the murderer in the past three months.
This is because we've checked the case data from the past few years and there were no similar cases of people going missing. This means that An An was the first victim.
There is a reason why people make choices. Even if there is no obvious reason, there must be a subconscious reason. The murderer must have chosen this time to commit the crime because something about him had changed.
There are many possibilities for this change, be it love, health, career, accident … No matter what, we can find the answer from his behavior. "
Ji Bai nodded solemnly. Xu Xu continued, "We previously concluded that the murderer has a strong desire to establish an intimate relationship with the victims. But why does he like this type of victim?
If one desired something, it must be because one was lacking something. What common characteristics did the victims have that deeply attracted him?
Was it young and beautiful? Was it because the murderer was old and ugly and felt inferior? Something was not right. If that was the case, he could have chosen simpler victims, such as younger students. Relatively speaking, they would be easier to trick than white-collar workers.
There are two more obvious characteristics about the victims. First, they have just graduated or are about to graduate. They have excellent qualifications and a bright future ahead of them. Their beautiful careers and lives have just begun. This' life boundary point 'is very clear. Second, look … "
Xu Xu spread out the photos of the two victims in the file. "Don't you think that they look more energetic and energetic than ordinary people?"
Ji Bai looked down and saw that the girls in the photo were all beautiful and had beautiful smiles on their faces. Their every move was lively and lively, and it was as if they were brimming with vitality.
Xu Xu looked at him. "So, I think there are two possibilities. One, the murderer has recently suffered a huge setback in his career. Two, the murderer is suffering from an incurable disease or is very difficult to cure. That's why he's attracted to this' vitality '.
No matter which one it was, the fact that the murderer had chosen them was very symbolic. It reflected that he might have wanted his life to be like theirs, to start all over again.
As a psychopath, his way of doing things was to plunder their bodies and lives. He's already addicted. "
Ji Bai was silent for a moment before he answered, "Continue."
Xu Xu nodded. "Secondly, the" Angel Killer "case was not publicized in the mainland. According to Senior Brother Yang Qinglin, there were only a few photos on a few mainstream BBS. They were posted in the middle of the night and within a few hours, all the posts were deleted and never circulated again. Therefore, not many people know about it. There are only two possibilities for the murderer to be so familiar with the case. One, he has a background in Hong Kong. Two, he was an online forum user. These people are usually university students or young white-collar workers.
Three, the choice of the body dump location shows that the murderer is very familiar with the forest area. He must have been going in and out of the forest area frequently in the past few months. Although there are many roads in the forest area without surveillance cameras, there are surveillance cameras on the main roads leading to the forest area in Lin City. We can take the surveillance footage from the traffic department for statistics.
Four, you mentioned last time that the murderer must have a secluded house and a very flexible working schedule. Only then could he follow and observe the victims. This is also one of the screening conditions. "
On a clear autumn morning, the house was warm and quiet. After listening to Xu Xu, Ji Bai did not immediately express his opinion. Instead, he pondered for a moment and answered, "These are all speculations of yours. There is no evidence to support them, and some of the conditions can't be traced. Even if some of the conditions can be screened, there will be a large number of people who fit the conditions. It can only be used as a supplementary attempt … I can arrange two criminal police officers for you at most. "
Xu Xu nodded. She had a strong feeling that they could definitely screen out such a person. However, objectively speaking, there were still many uncertain factors and it was possible that they would end up with nothing. Ji Bai wanted to control the overall situation, so it was impossible for him to arrange the main force. She could understand that.
"Alright, two people and me will be enough."
At this moment, Ji Bai smiled and got up to take a folder from the table and handed it to her. Xu Xu took a look and her face lit up.
Ji Bai said, "I've already asked Zhao Han to screen. There are more than 500 local private cars that have entered and left the forest area more than three times in the past three months. There are even more people in the city who own independent villas, warehouses, and houses in the suburbs. However, this should be able to save you some work. "
Ji Bai quickly arranged for two criminal police officers from the sub-bureau to report to Xu Xu. By the time Xu Xu called them and arranged their respective screening tasks, the sky was already bright.
Xu Xu had also been assigned heavy work, but she was too tired, so she lay down on the sofa in Ji Bai's office. "I'm going to sleep for a while."
Ji Bai also did not sleep the whole night. In a few hours, he still had to meet up with Da Hu and the others to investigate the second victim, Li Tiantian. He rubbed the space between his eyebrows and sat down beside Xu Xu. Xu Xu immediately crawled over and rested her head on his thigh. He smiled and picked up the draft paper on the table. "Do you like to write and draw like this when you're doing analysis?"
"I'll draw like this when I need to use my brain the most."
"Did you also draw like this on the pieces of paper that you left behind during Brother Lu's case?"
"Yes."
Ji Bai's slightly calloused fingers caressed her cheek. "Then why did you write a bunch of my names?"
Xu Xu closed her eyes and smiled without answering. After a while, she suddenly reacted and opened her eyes. Her face was slightly stiff. "That piece of paper couldn't have been handed in as evidence, right?" That would be so embarrassing.
"Of course it was handed in," Ji Bai said calmly. Xu Xu raised her hand to cover her face and sighed. Ji Bai looked at her blushing cheeks and a smile appeared on his face.
Logically speaking, he should have handed it in. However, in the end, he still acted on his own and cut off the piece of evidence. Now, the pile of pieces of her reasoning and yearning was kept in his drawer, lying together with the poor ring. However, he did not need to tell her for the time being.
Three days later, at noon, Xu Xu and her team members finally completed the heavy data screening work. When she saw the results of the cross-screening, she was stunned for a moment and whispered to her two assistants, "Keep it a secret." Then, she took the results to Ji Bai.
Ji Bai was talking to the plainclothes criminal police officers in charge of patrolling the mountain area. When he saw the report that Xu Xu handed over, he was also stunned. Soon, he hung up the phone and looked at her with his dark eyes.
Xu Xu nodded. "He's the only one in the city who's between 20 to 40 years old, has a Hong Kong background, was diagnosed with cancer in the city hospital within three months, frequently entered the forest more than five times within three months, and owns a villa in the forest."
All of the conditions did not seem to be directly related to the case and they were all just possibilities. However, if all of the possibilities were superimposed on one person, it would be thought-provoking.
Xu Xu continued, "Ji Bai, although we can't confirm that he's the murderer, the murderer sexually assaulted the second victim after his death. Serial killers won't change their methods easily, especially since this kind of assault will destroy their sexual fantasies about intimacy, unless their mentality is already unstable. Therefore, I'm guessing that he'll commit another crime soon … "
Ji Bai nodded with a sullen face. "Monitor Lin Qingyan 24 hours a day."
After that, the weather was gloomy for the next few days. As for the perverted killer, he seemed to have gone into hibernation and did not move at all. In the end, there was no such thing as an impenetrable wall in the world. Rumors about the killer gradually began to spread in Lin City …
Zhao Han and another criminal police officer were in charge of monitoring Lin Qingyan's villa. That evening, as usual, the two of them stayed in the forest and quietly guarded the place.
Suddenly, Zhao Han's phone rang. It was Da Hu. "Lin Qingyan drove out of the city and there's a woman in the car. We can't get too close, we can't see who it is."
Zhao Han and Da Hu braced themselves and when the sky turned completely dark, they saw a Buick commercial vehicle driving along the mountain road from afar. When they arrived at the entrance of the villa, a man walked out. Judging from his figure and clothes, it was Lin Qingyan. He opened the back door, leaned in and carried a woman out.
Zhao Han looked through the binoculars and saw that the woman seemed to have fallen into a deep sleep. Her long hair covered her face and she lay motionlessly in Lin Qingyan's arms. Lin Qingyan carried her into the villa and the lights were quickly turned on.
"Captain, what should we do?" Zhao Han asked Ji Bai through the phone.
Ji Bai said, "Let's wait a little longer."
The mountain was dark and the surroundings were silent. Zhao Han and Da Hu waited with rapt attention for a while. Suddenly, they heard a scream from the woman, followed by silence. Zhao Han and Da Hu's hearts skipped a beat.
If they acted now, they would definitely alert the enemy, but the police's principle was not to risk the safety of the victim. Ji Bai ordered in a deep voice, "Go in!"
Zhao Han and Da Hu ran down the hill and rushed to the door of the villa. From the window, they saw that the living room was brightly lit but there was no one there. Soft music could be heard from inside.
The two of them kicked the door open and followed the sound. Soon, they arrived at the door of the master bedroom in the innermost room. The door was ajar and the music was already very loud, but they could still vaguely hear the sobbing of a woman. Zhao Han did not hesitate anymore and pushed the door open, but he was stunned.
The two people in the house turned their heads at the same time and looked at them in shock.
Under the soft white light, the house was filled with blooming roses and a sea of red flowers. Yao Meng was sitting on the sofa in the middle of the roses with tears in her eyes. Lin Qingyan was kneeling on the ground with a black velvet ring box in his hand. He was putting a shiny diamond ring on her finger.
"Why are you …" Yao Meng helped Lin Qingyan to stand up. She reacted very quickly and asked in disbelief, "Are you suspecting that he's a serial killer?"
Zhao Han and Da Hu did not answer for a while. Lin Qingyan also turned his head to look at them and frowned in silence.
