Chapter 42 Criminal Psychology Genius
Jian Ruochen frowned, raised his hand and pointed to the alley outside the kitchen, "There is a green belt over there, go there if you want to vomit. Don't vomit here, it will destroy the crime scene."
Colin's face turned pale and blue.
What's the difference between this and publicly saying that he is in the way?
He even heard the trainee forensic doctor's laughter!
Jian Ruochen took a step back and said, "I gave you the handkerchief. You don't have to return it to me."
Got dirty stuff on it.
"If you can't stand it, go home early."
Colin nearly tore his handkerchief.
This is not being soft-tempered at all.
This is not taking him seriously!
In Jian Ruochen's eyes, he was not as important as a brick at the crime scene.
Jian Ruochen: "Are you here to deliver the documents? The superintendent of the forensic department is inside. Are you going to give it to me yourself or pass it on to me?"
Colin glanced at the pile of lunch boxes leaning against the wall from a distance, his face pale.
Where would he dare to go?
As soon as I thought about the boxes being filled with body parts, my feet felt like they were nailed to the ground and I couldn't move an inch.
Behind Jian Ruochen, the Inspector of the Forensic Science Department and the Superintendent looked at each other.
This consultant is awesome!
They have long been dissatisfied with the police in the Central and Western District.
Kowloon has good forensic resources and often helps police stations in various districts of Hong Kong test samples.
The Central and Western District relies on the fact that it is a key development area designated by the higher-ups. It has the largest number of British people and the most domineering attitude, as if they are superior to others just because there is an undersea tunnel between them.
Haha, who isn’t in a high-speed development zone?
The superintendent winked, and the forensic inspector immediately raised his hand to indicate OK, then glanced around the kitchen and said loudly, "Sir Guan, a large freezer was found in the kitchen, and it was full of frozen body parts."
Colin couldn't bear it any longer, and he stuffed the documents into Jian Ruochen's arms in a panic, then ran to the flower bed and vomited violently.
Jian Ruochen's eyebrows jumped, and he turned and walked to the inspector of the forensic department, glanced at the other party's name tag, and looked at Jingrong.
"To Sir, your documents."
Xiang Jingrong took it and looked at Jian Ruochen in surprise.
This calm consultant is in stark contrast to the frightened Colin!
Colin was more like a non-staff member in front of him.
What kind of consultant is Jian Ruochen?
Born to be a forensic doctor!
"Did you study medicine?" Xiang Jingrong asked as if he was chatting casually, while looking through the documents.
"Yeah, I learned a little bit." Jian Ruochen didn't want to talk about this and changed the subject subtly, "This kitchen seems to be quite big."
"There are signs of expansion. A freezer was built in the back, and there is a slaughterhouse underground." Xiang Jingrong took off a layer of gloves, took out a pen and wrote on the document. "This case is not easy to solve."
He sighed, "Ah... there's a major case at the beginning of the year. It looks like this year won't be peaceful."
The two of them walked into the crowd, one in front and one behind.
The evidence of the lunch box wall has been collected, and the positioning lines and photos have been taken.
The police officer from the photo section of the forensic department was so pale that he said, "Sorry, I only brought 5 rolls of film. We have to take pictures of the ice storage next, so we don't have enough..."
He carefully glanced at the inspector and the superintendent's faces and whispered, "Can you call the headquarters to send over the film?"
The police superintendent's eyebrows were full of anger. He shouted in a deep voice, "Why didn't you bring more when you came? Team A can only start investigating the case after the forensics are done. You let so many policemen wait for you?"
The police officer holding the camera turned pale and said, "I already brought extra. Two rolls are usually enough..."
Is there any other way now besides calling someone to deliver it or going back to pick it up myself?
You can't buy it with your own money, right?
High-end film is so expensive, and his salary is only over 3,000...
Jian Ruochen said: "The reporters outside should have brought empty film."
"Oh, they won't give it to them. Those films are like their lives." The police officer held the camera, his eyes red and tears were about to fall.
The feeling that everyone was waiting for him was particularly embarrassing.
What should I do? I won’t be unable to get a regular job because of this incident, right?
Jian Ruochen pursed his lips, reached into his pocket, took out a thousand Hong Kong dollars and handed it over, "Take the money and buy it from them, it's mine."
The police officer in the photo team held the money in both hands and said repeatedly, "Thank you, thank you."
Oh my god, the police officers in the serious crime squad all said that Jian Ruochen was generous, but they thought it was an exaggeration.
I didn't expect that he was not only generous, but also a nice person!
This is just like a god descending to earth. He will not go to Wong Tai Sin Temple this year. From today on, he will worship Jian Ruochen sincerely!
The police officer here hurried out to buy film.
On the other side, Guan Yingjun had already finished listening to the report and was waiting for the forensics department to finish their work and go to other areas.
Turning around, he saw Jian Ruochen talking and laughing with the people from the Forensic Department.
Xiang Jingrong chatted with Jian Ruochen: "I went to a few lectures by Professor Li Changyu before. I heard that criminal psychology can profile the murderer. Can you do it?"
Jian Ruochen: "A little bit."
He looked at Xiang Jingrong and asked, "Can I walk around there?"
Xiang Jingrong glanced at it and saw that the photos had been taken and the easily erasable marks had been arranged. "Okay."
Jian Ruochen walked over and walked around the kitchen workbench.
He scanned every spot with his eyes, looking at it very carefully.
Not far away, Zhang Xingzong, who had just recovered and was a little bored, even felt that Jian Ruochen would be like the detective on TV in the next second and point in a certain direction after watching.
Then he said: "He is the murderer."
Zhang Xingzong and Liu Sizheng whispered, "How much do you think he can see?"
Liu Sizheng: "I don't know...how much can you see?"
Zhang Xingzong: "The murderer doesn't like cleanliness..."
Bi Xianxian rolled her eyes and said, "You can see it with your eyes."
"Will he make a mistake?" Song Xuyi just finished speaking. Seeing his colleagues looking at him with strange expressions, he immediately explained, "I don't mean to hope that he makes a mistake. I'm worried that he will be sad after he makes a mistake. I don't look down on him now."
Zhang Xingzong said, "Oh," "It's okay."
He has realized that "those who dislike me, the God of Wealth, will eventually be convinced by me. As long as they don't break the law, it's just a small problem."
Guan Yingjun looked at Jian Ruochen steadily. This seemed to be the third case-solving skill that Jian Ruochen had demonstrated after bomb disposal and interrogation.
What could he see?
Jian Ruochen walked past and immediately said, "The kitchen stove is relatively low, and the murderer placed the lunch box only about 1.5 meters away, which means that this distance made him feel safe."
"The murderer is about 175cm tall, medium to short."
Zhang Xingzong flipped through the preliminary analysis sheet handwritten by the forensic department and found that it was indeed this height.
Jian Ruochen spoke very quickly, "The chopping board on the stove has a big dent, but it doesn't look like an old item that has been used for a long time, which means that the dent was made in a short period of time."
"The murderer is very strong."
Jian Ruochen pointed to the workbench and said, "The kitchen is not big. The entire workbench is filled with items, with almost no empty space. This is a typical manifestation of Asperger's syndrome."
"The murderer has the same social interaction disorder as autism, limited interests and repetitive, stereotyped activities. The dense placement of objects makes him feel safe."
The Superintendent of Forensic Science and Inspector Xiang Jingrong also came over. They were a little confused at this point. How could they feel safe?
Dirty and smelly.
Xiang Jingrong asked curiously: "If he is sick, then he is sick. What does it have to do with the case?"
Jian Ruochen: "This disease will make him put things within his reach. Look at the ground."
He said, making some room.
Everyone looked at the ground.
Jian Ruochen: "The murderer piled up lunch boxes full of body parts on the right hand side, placed a trash can at his feet, and piled up some old newspapers on the left hand side. Judging from the bloodstains on them, they should be used to absorb water."
"This concave shape surrounded by four sides will make him feel very safe."
"Normally he wouldn't leave so much space, and I could still walk and turn. This means that this position is OK for me, but it's probably a bit cramped for him."
“He should be fat.”
A short, fat man, about 1.75cm tall.
He suffers from Asperger's syndrome, has social disorders, cannot communicate with others, and is rather withdrawn.
Xiang Jingrong: ...
Just by looking at a kitchen, Jian Ruochen was able to obtain so much information.
He thought Jian Ruochen might be a genius in forensic medicine, but he didn't expect that he was a genius in criminal psychology.
Is this the feeling of being fed by your ancestors?
Zhang Xingzong was stunned.
In just a few minutes, you have a direction for the investigation?
Um?
What is this called?
"This is called suspect profiling." Jian Ruochen said.
He smacked his lips, wanting to drink some orange juice to suppress the foul smell in his throat. "I'm just average at this. A good person can tell a suspect's life story from childhood to adulthood with just one look at the scene. But I still need to rely on the forensic report."
Zhang Xingzong: This is called normal? If we go any further, we will have to rely on Sherlock Holmes in literary works.
Xiang Jingrong sighed again, "Fortunately, you still need to rely on the forensic report, otherwise I would be out of work."
Jian Ruochen smiled and said, "How can that be possible? A forensic doctor is a sacred profession that helps to redress the injustice of a corpse. He is the first person to arrive at the scene and is closest to the truth."
Xiang Jingrong felt so comfortable after being praised that he felt like he was about to be illuminated by holy light.
Jian Ruochen looked at the kitchen knife that was about to be put into the evidence bag by the Forensic Department.
The kitchen knife had two crescent-shaped notches, one in front and one in the back, which made the knife vaguely form an M shape.
This kind of knife must be difficult to cut with, and there is no way it could be the murderer's prop for dismembering the body.
Why did the murderer stay?
Is there any commemorative significance?
Jian Ruochen took a step forward and said, "Hello, can you let me see this knife?"
The police from the Forensic Science Department held the evidence bag and showed it to Jian Ruochen.
The empty m looks more obvious.
One on the front edge and one on the back edge.
It's as if two chefs with completely different knife usage habits have both used this knife.
"If one person was using this knife, the cut would definitely be in the same place..." Jian Ruochen turned around and looked at Zhang Xingzong, "How many suspects are there in this case?"
Zhang Xingzong was stunned, "There is only one at the moment."
He raised his hand and touched his nose. How did Jian Ruochen ask him?
Didn’t we always ask Sir Guan before?
Zhang Xingzong glanced at Guan Yingjun.
Sir Guan stood there, looking a little lonely.
I couldn't get a word in.
Zhang Xingzong walked over in small steps and asked quietly, "What happened between you and the Little God of Wealth?"
Guan Yingjun's Adam's apple moved, and he whispered, "I made him angry."
Jian Ruochen didn't pay attention to the person who was talking to Zhang Xingzong.
He now cares more about where the lunch box came from.
Jian Ruochen walked quickly to Song Xuyi and said, "Brother Song, have you measured the lunch box? How is the comparison? Is it exactly the same as the aluminum lunch box? It looks like they were cast from the same mold."
The boy gradually walked away, and his figure disappeared bit by bit.
Guan Yingjun took a deep breath, trying to dispel some of the bitterness and depression in his heart.
It turns out that emotions are so uncontrollable.
Zhang Xingzong looked at him and consoled him, "It's okay. Consultant Jian has a good temper. Just apologize and coax him. He will forgive you if you admit your mistake. Look at Song Xuyi. Jian Ruochen can call him Brother Song now. He doesn't hold grudges. He will definitely not be too angry with you."
Guan Yingjun shook his head.
He paused for a few seconds, then suddenly said, "The lighting in Group A is not very good."
Zhang Xingzong didn't understand: "Ah? I think it's quite bright."
Aren’t all the police stations equipped with that light?
It's been the same for so many years...
Guan Yingjun lowered his eyes, "It's a bit too bright."
Not good for the eyes.
I'll go back to the police station tomorrow and call to buy a new light to replace it.
Over there, Jian Ruochen got a definite answer.
The iron box used to hold body parts and the aluminum box used by Lu Qian to hold drugs were produced from the same mold.
Exactly.
"Actually... even if both lunch boxes are made from the same mold, it shouldn't mean anything..."
Song Xuyi hissed, fiddling with the translucent sulfuric acid paper in his hand that recorded the three-dimensional picture of the lunch box, and was a little confused. "Maybe the murderer just happened to buy this lunch box?"
