Criminal Investigation Notes

In the early morning of autumn, the world is 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 and faces, taking them away The remaining temperature.

The perverted murderer's attack again undoubtedly made people's heartstrings tense, and the murderer actually began to provoke publicly.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 a beast.

After the girl was sent away, Lu Siyu and Song Wen walked into the duty room.

The duty room of this parking lot is only about two square meters in size, with only one table and one chair inside.

The person in charge here has already withdrawn, and the electricity is still running.The lights in the duty room are now on, showing white light.

A small electric heater was inserted at the power supply above the table on the side. A cup was probably turned out 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 is still warm.

There is also a small note on the table, crookedly copying the report phone number of the city bureau.

Now, a colorful material evidence sign with an L-shaped ruler has been placed on the table, and the material evidence personnel have taken photos from various angles. They only wait for the last to put in the material evidence bag and go back for inspection.

Lu Siyu looked back at the hospital not far away. From this angle, you 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 off work.

The criminals wore the clothes of the security guard and defrauded her of her trust... and then...

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

The murderer was sitting here, took out a note prepared in advance, and used the victim's cell phone to call the municipal hotline.

He felt a little thirsty, found the water cup and heater, opened an unopened bottle of mineral water and washed it.Then I made a cup of tea and took a few sips indifferently.

Then he waited triumphantly and contentedly for the police to come, and even had a face-to-face meeting with the two policemen who came here first.

Song Wen also looked at everything in the small room. He brushed his hair back with his finger, then wiped the rain from his cheek with the back of his hand to restore his former calm.

Lin Xiuran was finally late at this time. He already knew that he had run in vain, but no new victims died, and there was no need to dissect the corpse. He was still in a very good mood.

Tonight, Lin Xiuran was wearing a dark green thick poncho. At this time, seeing Song Wen and Lu Siyu standing here, he walked over and stood at the door of the duty room and said: "I heard Has someone been rescued and sent away?"

Song Wen nodded tiredly.

Lin Xiuran said again: "It's a blessing to be saved."

"The murderer didn't use a lot of strength today, and the victim didn't have many traces of torture." Song Wen only breathed a sigh of relief and asked Xu Yao, who was collecting physical 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 had gone for a while.

Xu Yao said: "Lao Tian took a few people to try 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 it, but they had to try it.

Xu Yao said again, "Because it has rained here, there are not many traces left. We have already made almost everything in the security room, and work should be finished in half an hour."

Everything is still in order, Song Wen only now felt a little relieved.

He saw Lu Siyu standing beside him with a thoughtful appearance, and said to him: "Here I am staring at him. You can get warm in the car for a while, at least wipe your hair."

Lu Siyu shook his head: "I'm fine, I took the umbrella for a while, there is still something to do, but you..."

Song Wen was silent for a moment, then looked up and said, "The murderer has evolved again."

This evolution is in all aspects, the time interval between crimes has become shorter, and it has become more cunning.The murderer learned to disguise this time. The security suit may have been purchased by himself. Many ordinary people can't distinguish the difference between security uniforms, police uniforms, and police uniforms. They blindly think that they are good people.As long as you put on that suit, passers-by were less defensive towards 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: "Team Song, can you chat with me and Zhuang Yi?"

The air-conditioning was turned on in the city bureau's patrol car, and the temperature was warmer than outside, and it was also a lot drier. Sitting in the back seat, Zhuang Yi's eyebrows were drooping, and his expression was a little desolate.Seeing Song Wen and Lu Siyu come in, he smiled bitterly, and gave way inward.

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

Song Wen was not in a hurry, holding 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. At this time, it is almost ironic to hear this title. The professor is just a honorific title. The school specially hires me to be a visiting professor for popularity. I haven't taught a few classes at the university either."

As mentioned by the online Papipost, the professor is much different from the professor, and he has no formal professors.

Song Wen enlightened him: "The murderer is not against you, he himself is about to commit the crime again." He knew that the last call and the new victim this morning were very moved to Zhuang Yi.

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 somewhat suspected that Lu Siyu was just to trick him into getting in the car to warm up.

Zhuang Yi sighed and said: "I'm really just talking on paper. It's too far away from these abnormalities in life..."

He has never said this in front of outsiders, but today he saw a new victim, and his heart felt guilty, like a stone weighing heavily on his chest.He suddenly realized that the few words he sometimes fluttered were human lives underneath.

"Profile of behavior, after all, is not a prediction." Song Wen comforted him.

Lu Siyu rolled a car window that was half open, and then sat aside and opened his mouth: "The matter is over, and there is another victim. We must accept this fact." He licked his lips. Continued, "The situation is a bit unfavorable, but there is hope. The more the murderer commits the crime, he exposes himself and makes it easier for us to approach him.

These words he said sounded cold and ruthless, but in fact they made sense.

Many unsettled cases in history, one is because the technical investigative methods at the time were unable to keep up, and the other was because the murderer had committed too few crimes to extract more clues and features, and became unsolved cases.This is typical of these, 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, peel off the thread, find out the truth of the case, and restore the psychology of the murderer is what they should do now.

At the noisy crime scene, the rain outside was still falling, and the rustling rain was blocked by the rolling window. The three of them were sitting in the car, with orange-yellow rear lights illuminating their faces.

Lu Siyu continued: "Professor Zhuang, I think your inference is not 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. The girl said that there was only one murderer. My previous inferences were just my imagination."

What is not entirely wrong, but the little policeman is saving him face.He didn't see Lu Siyu many times, but he had some impressions a few times, and he always felt that this little policeman was something unusual.

"I have already said everything I can think of before, but now I still can't figure out what went wrong with my thinking." Zhuang Yi sighed, still frustrated, at that time, combined with the first place According to the witness testimony, he almost thought his theory was perfect, but the facts slapped him in the face.

"This case requires you to work harder. As a consultant, I have to clean up my previous mess. I estimate that in two hours, my phone call will be blown up by the media. I will tell Gu Ju later to quit this Case." Zhuang Yi encountered a setback, and did not want to face the difficulties, but was thinking about how to make up for the loss and how to save his reputation.

Lu Siyu shook his head and pointed out the irrationality in his previous reasoning: "I think the murderer is not two people, but a dual personality."

Zhuang Yi's eyes opened wide, "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 makeup on women. It is the most common non-waterproof cosmetics. Therefore, the girl’s makeup was soaked in heavy rain, making her face look imperfect. And do you remember that in the initial profile, the murderer was paranoid about details and pursued perfection ."

Zhuang Yi thought about it: "You mean, the makeup is before the heavy rain?"

The girl was killed in shock not too long before they arrived at the scene.It is inferred from this that when the murderer called, it was when he was most proud of the end of the attack, so that's when he left such provocation and laughter.Then heavy rain fell, so makeup was not done after the attack.

Song Wen also suddenly understood at this time, adding: "The makeup may be applied before strangulation, while the victim was in a coma."

Lu Siyu nodded his head: "The two personalities are not one evil or one guilt. It is a violent personality that captures prey..." He paused and continued, "The other abnormal personality completes the makeup and the final Kill."

At this time, Lu Siyu’s hair was wet, and the wet hair was hanging on the sides of the snow-white forehead. It might be because of some coldness. His lips were so pale that there was no blood, but his eyes were sharp. Like a sword, he seemed cold and rational as a whole.

The theory that Lu Siyu uttered shocked Zhuang Yi for a while. He frowned and lowered his head to think about it, but found that it was in full compliance with the actual situation of the case.

Lu Siyu stretched out his slender fingers and said four words: "We previously divided the murder into four steps: hunting by violence, controlling the victim, killing the victim, and dressing up the corpse."

Then, while talking, Lu Siyu gathered his fingers one by one: "But the actual sequence is: hunting by violence, controlling the victim, dressing up, killing the victim. His pretending behavior, and giving the victim a face The act of putting clothes on makes you mistaken for guilt and pity, but in fact, those steps are for him to enjoy better."

Lu Siyu summed it up seriously and earnestly: "After controlling the victim, the murderer had a personality change. This is why our former witness heard him seem to be talking to others. It was also your mistake. I thought the murderer had a helper."

"Then...why did a personality change happen at that point?" Zhuang Yi asked a question, this is what has been confusing him.
