Lu Wan's meaning is very clear. She does not believe that this case was committed by the same murderer.
Among the people present, only Bai Mo showed an excited expression. After seeing Duan Xuanxuan stabbed in the waist, Bai Mo also thought about whether the murderer might not be the same person.
Bai Mo didn't know what Lu Wan's basis was. His idea was very simple. The murderer had a strong obsession with women's thin waists, just like Bai Mo was obsessed with some oil paintings. With this obsession, no matter how out of control he was, he would be obsessed with it. Won't damage it.
"The inference you mentioned is indeed possible, and I don't agree to join the case just because the murderer pulled a knife on the waist of the deceased." Lu Wan circled the word "fruit knife" on the whiteboard.
Lu Wan said, "There is a paradox in your statement. If the murderer had decided to use a fruit knife to control the deceased, why did he beat him first? And why didn't he carry the murder weapon himself? What if there was no suitable place for him in the deceased's home? What about controlling the deceased’s murder weapon?”
This question really stopped everyone. Even Lin Feng, the captain of the second team who was the most determined just now, took a breath.
Lu Wan added the word desire to conquer, "When the murderer committed the crime against Tang Xueqiong, he controlled Tang Xueqiong by beating him or using a fruit knife to control him. Which method do you think can satisfy his desire to conquer?"
Seeing that everyone looked shaken, Lu Wan added: "You just have preconceived notions. The scene of this crime is too similar to the scene where Tang Xueqiong was killed, so you subconsciously believe that the two cases were committed by the same murderer." Because, and then looking for a reasonable process based on consequentialism, we went into a misunderstanding."
The first person to be persuaded was Bai Yonghui. He sighed, "Don't forget that many details of the Tang Xueqiong case have been exposed online. If someone wants to imitate the crime, they can indeed do it."
In fact, Lu Wan knew very well that she was also a consequentialist. Because the murderer drew a knife on the waist of the deceased, she subconsciously believed that it was not the same murderer, so she looked for a reasonable explanation.
If it were Lu Wan from a few years ago, she might also investigate the case together, but this year's study has allowed her to see too many cases of serial killers, so she firmly believes that the murderer will not stab him in his favorite waist.
After all, Meihai City is just a small city, and both criminal investigation conditions and personal abilities are lacking. She must use her own way to let everyone truly understand the serial killer.
The two cases were investigated separately. The biggest advantage of this case is the existence of witnesses. As long as Bai Mo can draw the murderer's appearance based on Liu Xin's description, this will be a simple home invasion murder case.
Bai Mo knew that the next step was his moment of performance. He stood up, nodded to Lu Wan, and walked out of the office with a sketchpad and pencil.
Bai Yonghui noticed that Lu Wan's expression was not good, and he couldn't help but feel a little confused. Logically speaking, Lu Wan had convinced everyone, so she should be very happy. Why didn't she have any intention of relaxing?
Lu Wan suddenly said: "Speed up the progress of the investigation. Once the murderer knows about this copycat murder, it will probably stimulate him. He will not be far from committing the next crime."
······
In the reception room of the Public Security Bureau, Bai Mo walked in with a drawing board under his arm. The layout of the room was very simple, with a row of sofas, a coffee table, a water dispenser and several cabinets.
Liu Xin sat on the sofa, legs together, hands on her thighs wrapped in black stockings, holding a disposable cup.
The makeup on her face had been washed off and there was no cosmetic modification. Bai Mo could clearly see the freckles on Liu Xin's face, and Liu Xin's bright big eyes had turned into small eyes at this moment.
Bai Mo pulled up a chair and sat across from Liu Xin, asking softly: "How are you feeling?"
Handsome-looking boys will always gain points in front of any woman, especially those like Bai Mo, an internet celebrity.
Liu Xin's eyes stayed on Bai Mo's face for a moment, then nodded slightly, "Much better."
"I am a portrait artist of the police force. I need you to help me recall the appearance of the murderer." Bai Mo's voice was still very soft, making people feel irresistible.
When Liu Xin heard about the request for a portrait, she paused and shook her head, "That person was wearing a mask, and I couldn't see his face clearly."
"Haha!" Bai Mo smiled knowingly and comforted, "Even if you didn't see all of his appearance, you saw part of him? Just tell me the part you saw."
While talking, Bai Mo put the drawing board on his legs and held the pencil in one hand. The tip of the pencil touched the white paper on the drawing board. The moment the two came into contact, Bai Mo's eyes became bright.
"Oh!" Liu Xin's eyes were a little dazed, obviously she thought Bai Mo was making up a fantasy.
"Is this person fat or thin?" Bai Mo asked.
"Skinny." Liu Xin replied suspiciously. She thought that Bai Mo would ask some particularly detailed details, but she didn't expect that this kind of question would come up.
"What about height?"
Liu Xin replied: "It should be more than 1.8 meters, right?"
Bai Mo looked up at Liu Xin, "Compared to mine, his eyes are bigger or smaller?"
Liu Xin thought for a while and said, "It's too small."
Bai Mo asked: "What about the eyebrows? Do they have any characteristics?"
Liu Xin slowly shook her head, "I have no impression."
Bai Mo smiled slightly, "Having no impression is also a characteristic. It can be seen that his eyebrows have no characteristics and the corners have no angle."
Bai Mo's pencil kept moving on the drawing board, as if Liu Xin had given him many characteristics, "What about the ears? Do they have any characteristics?"
"I can't remember." Liu Xin frowned and looked at the ceiling, "It doesn't seem to have any characteristics."
At this time, Bai Mo's writing stopped. He looked at Liu Xin, with a comfortable smile still on his face, "What you saw was his front, right?"
Liu Xin nodded repeatedly, "His hair is a bit long, so I didn't see his ears clearly."
Bai Mo's pencil continued to wander on the drawing board, "He is wearing a mask. Do you feel that his cheeks are holding up the mask?"
"No!"
"What about the chin?" Bai Mo said, "If the chin is longer, the mask will expand at a larger angle. Do you think his chin is longer or shorter?"
"Short." Liu Xin replied without thinking.
At this moment, Bai Mo's eyebrows twitched as he lowered his head, and he asked again: "What about the forehead? Is it big? Is it three-dimensional?"
Liu Xin thought for a while and said: "It's not big, it has some three-dimensionality."
Hearing Liu Xin's answer, Bai Mo took a deep breath, uncovered the prototype of the portrait, put it under the drawing board, and then started to draw again. After finishing one picture, Bai Mo drew another. .
The only sound left in the room was the sound of pencil rubbing against white paper.
Ten minutes later, Bai Mo had used three pieces of paper. He took out the prototype of the last portrait and showed it to Liu Xin. The picture showed a man wearing a mask.
"Is it him?" Bai Mo asked in a low voice.
Liu Xin did not answer, but nodded in surprise.
