Criminal Investigation Files

In the early morning of autumn, the world was shrouded in darkness and heavy rain. The sound of the rain was endless. The heavy rain washed away most of the traces. The cold rain continued to fall on people's bodies and faces, taking away remaining temperature.

The second attack by the perverted killer undoubtedly made people's hearts tense, and the murderer even started to openly provoke.What else is he afraid to do?

This person has given up the bottom line of being a human being. Such behavior is no different from that of 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 inside.

The person in charge has already withdrawn, and the electricity is still on.Now the lights in the duty room are on, revealing white light.

A small electric water heater was plugged into the power supply above the table on the side. A cup was probably turned out of the pocket of the table 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 piece of paper on the table, with the city bureau's reporting telephone number scrawled crookedly.

Now, a colored physical evidence sign with an L-shaped scale has been placed next to the items on the table, and photos from various angles have been taken by the physical evidence personnel, and they are only waiting to be put into the physical evidence bag at the end 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 of resuscitating the patient and met the murderer on the way home from get off work.

The criminal dressed up as a security guard and tricked her into trusting her... and then...

A picture appeared in Lu Siyu's mind. After the cruel thing was done just now, the murderer came here. Seeing the rain getting heavier, he entered this small room and turned on the light.

The murderer was sitting here, took out the note he had prepared in advance, and used the victim's mobile phone to call the hotline of the Municipal Bureau.

Feeling a little thirsty, he rummaged through to find the water cup and heater, and opened a bottle of unopened mineral water to wash it off.Then he made a cup of tea and took a few sips calmly.

Then he waited proudly and contentedly for the police to arrive, and even had a face-to-face meeting 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 former composure.

Lin Xiuran finally came late at this time. He already knew that his trip was in vain, but no new victim died, and there was no need for an autopsy. He was still in a very good mood.

Tonight, Lin Xiuran was wearing a dark green thickened poncho. Seeing 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 The person was rescued and sent away?"

Song Wen nodded wearily.

Lin Xiuran said again: "It is a blessing among misfortunes to be saved."

"The murderer didn't use a lot of strength today, and the victim didn't have many signs of abuse." Song Wen finally breathed a sigh of relief, and asked Xu Yao who was collecting evidence outside: "Sister Xu, where is Lao Tian?"

The ambulance was there just now, and there were so many people, he didn't notice where Tian Ming went for a moment.

Xu Yao said: "Lao Tian brought a few people to try to catch up with the murderer nearby. 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.

Xu Yao said again: "Because of the rain here, there are not many traces left outside. We have almost finished the things in the security room just now. We should be able to call it a day in half an hour."

It was considered that everything was in order, so Song Wen felt a little relieved.

Seeing Lu Siyu standing aside 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 brush your hair."

Lu Siyu shook his head: "I'm fine, I've held up an umbrella for a while, and my body is still dry, but you..."

Song Wen was silent for a moment, then raised his head and said, "The murderer has evolved again."

The evolution is all-encompassing, with crimes getting shorter and more cunning.The murderer learned to disguise this time. He might have bought the security uniform himself. Many ordinary people can't tell the difference between security uniforms, police uniforms, and police uniforms. They blindly think that those who wear them are good people.As long as he puts on that suit, passers-by will be much less wary of him.

Lu Siyu lowered his head and bit his thumbnail, sorting out the process of several cases in his mind. After a while, he raised his head and said, "Captain Song, can you chat with Zhuang Yi with me?"

The air conditioner was turned on in the patrol car of the Municipal Bureau, and the temperature was warmer than outside, and it was also a lot drier. Zhuang Yi, who was sitting in the back seat, lowered his brows and looked a little downcast.Seeing Song Wen and Lu Siyu come in, he gave a wry smile, and moved in to give way.

Lu Siyu sat down, took a tissue from the tissue box at the side, wiped the water droplets on his face, then pulled a few and handed them to Song Wen.

Song Wen was not in a hurry, held the tissue in his hand, and said hello to Zhuang Yi: "Professor Zhuang."

Zhuang Yi raised his head and said, "Don't call me Professor Zhuang, just call me Zhuang Yi. It's ironic to hear this name at this time. Professor is just a respectful title. The school specially hired me as a guest professor for the sake of popularity. I also didn’t go to university to teach a few classes.”

As the online scraping posts said, there is a lot of difference between a professor and a professor, and he does not have a formal professorship.

Song Wen enlightened him: "The murderer didn't target you, he was going to commit the crime again." He knew that the last phone call and the new victim this morning had greatly touched Zhuang Yi.

After Song Wen finished speaking, he looked at Lu Siyu. He still didn't know what Lu Siyu wanted to say to Zhuang Yi, and seeing his unhurried appearance, he suspected that Lu Siyu was just trying to trick him into getting in the car to warm up.

Zhuang Yi sighed and said, "I'm really just talking on paper, I'm too far away from these perverts in life..."

He never talked about this in front of outsiders, but seeing a new victim today, he felt guilty, like a stone weighed heavily on his chest.He suddenly realized that some of his frivolous words sometimes had someone's life behind them.

"Behavioral profiling is not a prophecy after all." Song Wen comforted him.

Lu Siyu rolled up a half-open car window, and then sat aside and said, "This is the end, and there is another victim, we have to accept this fact." He licked his lips He continued, "The situation is a bit unfavorable, but there is still hope. The murderer will expose himself one more time if he commits another crime, making it easier for us to get close to him."

What he said sounds cold and heartless, but in fact it makes a lot of sense.

There are many unsolved cases in history, one is because the technical investigation methods at that time could not keep up, and the other is because the murderer committed too few crimes and could not extract more clues and characteristics, so they became unsolved cases.This is typical of them, such as the Black Dahlia and the Nanda Corpse Case.

Now, although there is one more victim in this case, at the same time, the murderer has left them with more clues and evidence.

How to gather all the clues, unravel 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 rear lights.

Lu Siyu continued: "Professor Zhuang, I don't think your deduction is completely wrong. Only by correcting it can you get closer to the murderer."

Zhuang Yi smiled bitterly: "I just heard a policeman say when he came in to put things away. The girl said that there was only one murderer. My previous inference was just my imagination."

Nothing is completely wrong, but this little policeman is trying to save face for him.He didn't meet Lu Siyu many times, but the few times left him with some impressions, and he always felt that there was something unusual about this little policeman.

"I've already said everything I could think of before, but up to now, I still can't figure out what's wrong with my thinking." Zhuang Yi sighed, still depressed. At that time, combined with the first Based on the testimony of eyewitnesses, he almost thought that his theory was flawless, but the facts hit him hard in the face.

"This case requires you to work harder. As a consultant, I still have to clean up my previous mess. I estimate that after two hours, my phone will be blown up by the media. I will tell Director Gu later to quit this project." case." Zhuang Yi encountered twists and turns, and didn't 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, pointing out the irrationality in his previous reasoning: "I think the murderer is not two people, but a dual personality."

Zhuang Yi's eyes widened leisurely, "But before I..."

"That's right, in the initial discussion, your analysis denied this kind of answer." Lu Siyu said, "But today, I noticed a detail, he didn't use high-end cosmetics for the women, but It is the most common cosmetic that is not waterproof. So, the heavy rain soaked the girl's makeup, making her face look less than perfect. And do you still remember that in the original profile, the murderer was paranoid about details and pursued perfection .”

Zhuang Yi thought for a while: "You mean, the makeup was done before the heavy rain?"

It wasn't too long before they arrived at the scene when the girl was killed and went into shock.Based on this, it can be inferred that when the murderer called, it was just after the murder was over and he was at his happiest, that's why he left such provocations and laughter at that time.Then heavy rain fell, so the make-up was not done after the murder.

Song Wen also suddenly understood at this time, and added: "The make-up may have been done before the strangulation, while the victim was unconscious."

Lu Siyu nodded his head: "The two personalities, one is not evil, the other is guilty. It's a violent personality catching prey..." He paused and continued, "The other perverted personality completes the makeup and the last kill."

At this time, Lu Siyu's hair was wet, and those wet hairs were hanging on both sides of his snow-white forehead, probably because of the cold, his lips were so pale that there was no blood, but his eyes were sharp Like a sword, it seems that he is cold and rational.

Zhuang Yi was shocked by Lu Siyu's theory for a moment. He frowned and lowered his head to think carefully, but found that it was completely in line with the actual situation of the case.

Lu Siyu stretched out his slender fingers, and made a four-character gesture: "We divided the murder case into four steps: violent hunting, controlling the victim, killing the victim, and dressing up the corpse."

Then Lu Siyu put his fingers together one by one while talking: "But the actual sequence is: violent hunting, controlling the victim, dressing up, killing the victim. His dressing up, and giving the victim a face The act of putting the clothes on makes you mistake it for guilt and pity, but in fact, those steps are for his better enjoyment."

Lu Siyu concluded seriously and earnestly: "After controlling the victim, the murderer underwent a personality change. That's why our previous witness heard him seem to be talking to someone else. It's also because you misunderstood him. The reason for thinking that the murderer has an assistant."

"Then...why did the personality change happen at that step?" Zhuang Yi asked the question, which was what puzzled him all the time.
