In the early morning of autumn, the heaven and earth are shrouded in darkness and heavy rain, the sound of rain is endless, the heavy rain has washed away most of the traces, and the cold rain keeps falling on people's bodies and faces, taking away remaining temperature.
The perverted murderer's re-attack undoubtedly made people's heartstrings tense, and the murderer even started a blatant provocation. What else could he dare not do
This person has given up the bottom line of being a human being. Such behavior is no different from a beast.
After the girl was sent away, Lu Siyu and Song Wen walked into the duty room.
The duty room in this parking lot is only about two square meters in size, and there is only one table and one chair in it.
The person in charge of this place has long since withdrawn, and the electricity is still on. The lights in the duty room are now on, revealing a white light.
A small electric water heater was plugged into the power supply above the table on the side. A cup was probably turned over from the table pocket on the side. The cup was cleaned, and a tea bag was carefully placed in it. There is an empty mineral water bottle. At this time, the cup of tea was still warm.
There was also a small note on the table, with a crooked copy of the city bureau's report number.
Now, next to the items on the table, colored physical evidence signs with L-shaped scales have been placed, and photos from all angles have been taken by the evidence personnel, and they are only waiting to be put into the evidence bag and go back for inspection.
Lu Siyu looked back at the hospital not far away. From this angle, he could see the red cross light on it.
The victim may have just come out after rescuing the patient, and met the murderer on the way to get off work.
The criminals wore the clothes of the security guards and cheated her of her trust... Then...
A picture appeared in Lu Siyu's mind. After the cruel thing was done just now, the murderer came here. Watching the rain was getting heavier and heavier, he entered the small room and turned on the light.
The murderer was sitting here, took out the prepared note, and used the victim's mobile phone to call the city bureau's hotline.
Feeling a little thirsty, he rummaged through the water cup and heater, opened an unopened bottle of mineral water and washed it. Then made a cup of tea and took a few sips indifferently.
Then he waited for the police to arrive smugly and contentedly, and even had a face-to-face with the two policemen who arrived here first.
Song Wen also looked at everything in the small room. He combed his hair back with his fingers, and then wiped the rain on his cheeks with the back of his hand to restore his composure.
Lin Xiuran finally arrived late at this time. He already knew that he had gone all in vain, but no new victims died, and he didn't need to autopsy the body. He was still in a very good mood.
Tonight, Lin Xiuran was wearing a dark green thick poncho, when he saw Song Wen and Lu Siyu standing here, he walked over, stood at the door of the duty room and said, "I heard that the victim was injured. The person was rescued and sent away?"
Song Wen nodded tiredly.
Lin Xiuran said again: "It's a blessing among misfortunes to be rescued."
"The murderer didn't use a lot of strength today, and the victim didn't have many traces of abuse." Song Wen was relieved only now, and asked Xu Yao, who was collecting evidence outside, "Sister Xu, where is Laotian?"
The ambulance was there just now and there were so many people, he didn't notice where Tian Ming went.
Xu Yao said: "Old Tian brought a few people and went to the neighborhood to see if he could catch the murderer. But here, there are small forks everywhere..."
Song Wen nodded, there was little hope of being able to catch up, but they had to try it.
Xu Yao added: "Because it has rained here, there are not many traces left outside. We have almost finished the things in the security room just now, and we should be able to finish work in half an hour."
After all, everything was in order, Song Wen was relieved a little.
Seeing Lu Siyu standing beside him with a thoughtful look, he said to him, "I'm watching over here, you go to the car to warm up for a while, at least wipe your hair."
Lu Siyu shook his head: "I'm fine, I held an umbrella for a while, and I still have room to work, but you..."
Song Wen was silent for a moment, then raised his head and said, "The murderer has evolved again."
This evolution is all-encompassing, the time interval between crimes has become shorter, and it has become more cunning. The murderer learned to disguise this time, and the security suit may have been purchased by him. Many ordinary people cannot distinguish the difference between security uniforms, police uniforms, and assistant police uniforms, and blindly think that those who wear them are good people. As long as he put on that outfit, passersby would be less defensive about him.
Lu Siyu lowered his head and bit the nail of his thumb, sorting out the process of several cases in his mind. After a while, he raised his head and said, "Song team, can you chat with me and Zhuang Yi?"
The air conditioner was turned on in the city bureau's patrol car, and the temperature was warmer and drier than the outside. Zhuang Yi, who was sitting in the back seat, had lowered eyebrows and a depressed expression. Seeing Song Wen and Lu Siyu come in, he smiled wryly, and gave way inside.
Lu Siyu sat down, took a tissue from the tissue box on the side, wiped the water droplets on his face, and then pulled a few and handed it to Song Wen.
Song Wen was in no hurry, he held the tissue in his hand and greeted Zhuang Yi, "Professor Zhuang."
Zhuang Yi raised his head and said, "Don't call me Professor Zhuang, just call me Zhuang Yi. When I hear this title at this time, it's like sarcasm. Professor is just an honorific title. The school specially hired me as a visiting professor for the sake of popularity. I didn't even go to college to teach a few classes."
As the online scraping post said, there is a lot of difference between professors and professors, and he is not prepared by formal professors.
Song Wen enlightened him: "The murderer is not targeting you, he himself is going to commit the crime again." He knew that the last phone call and the new victim this morning touched Zhuang Yi a lot.
After Song Wen finished speaking, he looked at Lu Siyu. He still didn't know what Lu Siyu was going to say to Zhuang Yi, and seeing how he was not in a hurry, he suspected that Lu Siyu was just trying to trick him into getting into the car to warm up.
Zhuang Yi sighed and said: "I'm really just talking about soldiers on paper, and I'm too far away from these perverts in life..."
He has never said this in front of outsiders, but seeing the new victim today, he felt guilty, like a stone was pressing heavily on his chest. He suddenly realized that some of his sometimes fluffy words were filled with life.
"The profile of the behavior is not a prophecy after all." Song Wen comforted him.
Lu Siyu rolled up a half-open car window, then sat aside and said, "This is the end of the matter, and there is one more victim, so we must accept this fact." He licked his lips Continuing, "The situation is a bit unfavorable, but there is still hope. The murderer commits one more murder, and he exposes himself one more point, making it easier for us to approach him."
The words he said sounded indifferent, but they made a lot of sense.
Many unsolved cases in history became unsolved cases because the technical investigation methods at the time could not keep up, and the murderer committed too few crimes and could not extract more clues and features. The typical ones, such as the black dahlia and the Nanda corpse case, are all like this.
Now, in this case, although there is one more victim, at the same time, the murderer has left them more clues and evidence.
How to gather all the clues, peel off the thread, find out the truth of the case, and restore the murderer's psychology is what they should do now.
At the noisy crime scene, it was still raining outside, and the rolled up car windows blocked the rustling rain. The three of them sat in the car, their faces reflected by the orange-yellow rear lights.
Lu Siyu continued: "Professor Zhuang, I don't think your inference is completely wrong. Only by correcting it can you get closer to the murderer."
Zhuang Yi smiled bitterly: "I heard a policeman say when he came in to put things. The girl said that there was only one murderer. My previous inference was just my imagination."
Nothing is completely wrong, but the little policeman is saving face for him. He didn't see Lu Siyu many times, but several times he had some impressions, and he always felt that there was something unusual about this little policeman.
"I've said everything I can think of before, but now, I still can't figure it out. What's wrong with my thinking." Zhuang Yi sighed, still dejected. At that time, combined with the first Eyewitness testimony, he almost thought his theory was flawless, but the facts hit him hard in the face.
"This case requires you to work hard. As a consultant, I have to clean up my previous mess. I estimate that in two hours, my phone will be blasted by the media. I will tell Gu Bureau later, quit this The case." Zhuang Yi encountered setbacks and did not want to face the difficulties, but was thinking about how to make up for the losses and how to save his reputation.
Lu Siyu shook his head and broke the unreasonable part of his previous reasoning: "I think the murderers are not two people, but dual personalities."
Zhuang Yi's eyes widened leisurely, "But before I..."
"Yes, in the initial discussion, your analysis denied this answer." Lu Siyu said, "but today, I noticed a detail, he did not use high-end cosmetics for women, but It is the most common non-waterproof cosmetic. So, the heavy rain soaked the girl's makeup and made her face look less than perfect. And do you remember that in the initial profile, the murderer was paranoid about details and pursued perfection ."
Zhuang Yi thought for a while: "You mean, the makeup is before the heavy rain?"
It wasn't long before they arrived at the scene when the girl was killed in shock. It can be inferred from this that when the murderer called, he was the most proud when the murder had just ended, so that provocation and laughter were left at that time. Then it rained heavily, so make-up was not done after the murder.
Song Wen also suddenly understood at this time, and added: "The makeup may have been done before strangulation, while the victim was in a coma."
Lu Siyu nodded: "The two personalities are not one evil, one guilty. They are one violent personality catching prey..." He paused and continued, "The other perverted personality completed the makeup and the final killing. ."
At this moment, Lu Siyu's hair was wet, and the wet strands of hair hung down on both sides of his snow-white forehead. Maybe it was because of the cold. His lips were pale to bloodless, but his eyes were sharp. Like a sword, it seems that his whole person is cold and rational.
The theory that Lu Siyu said shocked Zhuang Yi for a while. He frowned and lowered his head to think about it, but found that it completely matched the actual situation of the case.
Lu Siyu stretched out his slender fingers and compared four words: "We previously divided the murder into four steps: violent hunting, controlling the victim, killing the victim, and dressing the corpse."
Then Lu Siyu put his fingers together while talking: "But the actual sequence is: violent hunting, controlling the victim, dressing up, and killing the victim. His act of dressing up, and giving the victim face The act of covering up makes you think it's guilt and pity, but in reality, those steps are for his better enjoyment."
Lu Siyu concluded solemnly and earnestly: "After controlling the victim, the murderer underwent a personality transformation. That's why our previous witness heard that he seemed to be talking to someone else. It's also your mistake. The reason for thinking that the murderer had an assistant."
"Then...why does the personality change occur at that point?" Zhuang Yi asked a question, which has always puzzled him.
