Qin Youwei stared at the hand painting for a long time, and when he looked at Lu Wan again, his eyes hesitated.
"It doesn't make sense!" Qin Youwei said, "The man's limbs and head were cut open in the painting. If you look at the blood splattering on the stage, you can't even find the position where the murderer was standing when the knife fell! Also! The distance between the limbs and the body is almost the same, so the force of the murderer's knife is very close every time."
"Five consecutive knives, each with almost the same power, and the knives were struck continuously. Even a professional killer couldn't do it, right? All I could think of was a chainsaw, but the cuts on the deceased were completely smooth, and it couldn't be a chainsaw. "
Lu Wan smacked his lips, "We can also see these problems. Now you must give me a method that can realize the killing in the painting."
Qin Youwei rolled his eyes and returned to the painting.
After watching for a long time, Qin Youwei muttered: "Why are you so sure this is a murder case and not a prank?"
No one answered Qin Youwei, he could only sigh and continue to observe.
Bai Mo glanced at Lu Wan secretly. Lu Wan was frowning at the moment, obviously thinking about the murder method in the painting.
In fact, Bai Mo was also very surprised. Why did Lu Wan confirm that the scene in the painting really happened after seeing this painting?
"Uncle Qin?" Bai Mo reminded in a low voice, "Do you think the angle of view in the painting is strange?"
"It's indeed strange." Qin Youwei nodded, "This is a bird's eye view, as if the murderer is on the second floor and the deceased is on the first floor..."
As he spoke, Qin Youwei began to move his hands.
I saw Qin Youwei holding his hands together, first lifting them up, and then lowering them.
After repeating it five or six times, Qin Youwei cursed, "Damn, are you so evil?"
Lu Wan slowly looked at Qin Youwei, "Did you also think of a specially made killing tool?"
"Yes!" Qin Youwei nodded quickly, "It may be a tool with five sharp and large blades fixed on it. Add weight to the back, and then use a rope to pull the tool up. Then let go of the rope, and the tool will fall rapidly, using gravity to complete the simultaneous separation. corpse!"
Qin Youwei strode to the whiteboard and drew a sketch on the whiteboard.
There are five blades in total, corresponding to the human limbs and head. The upper one looks like a cursive head, and the lower one looks like an upside-down eight-character head.
Qin Youwei clicked his tongue and said, "If this is true, the murderer is probably not a super pervert, right? He has to first determine the target, and then customize the tool according to the opponent's shoulder width and hip width, so that he can kill!"
"It's really true." Lu Wan said seriously.
Qin Youwei still didn't completely believe it, otherwise he wouldn't have added "if this is true" when expressing his inference.
"I have seen this dismembered corpse." Lu Wan's deep voice sounded in the office.
In addition to Bai Mo and Qin Youwei, there was Sun Xiaokai who had been silent in the office. The three of them looked at Lu Wan at the same time, their eyes full of shock.
Lu Wan took a deep breath, "While investigating Lu Yajun's case, the second deceased, Tang Xueqiong, once went to a convenience store. I saw this person on the way to the convenience store. He was a homeless man."
Seeing that the three of them were still silent with their mouths wide open, Lu Wan asked angrily: "You don't believe in my memory, do you?"
"Believe it!" Qin Youwei answered first, "They don't know you, don't I? Your memory is definitely not wrong!"
"Then why don't we go find the homeless man?" Sun Xiaokai asked, "What if he is not dead and the murderer just drew a portrait based on his appearance?"
Lu Wan said: "I have just contacted the police station in the jurisdiction over there to look for him, but the murderer has no fixed address and it is difficult to find him. The reason why I believe he was killed is mainly because of his state in the painting. His skin is clean and his hair has been taken care of.
But when I saw him before, he was wearing a set of dirty clothes, his hair was disheveled, and his hands and face were covered in dirt. I don't think the killer went out of his way to cover this up when he painted the deceased. "
Bai Mo nodded in agreement, "It shouldn't be a cover-up. Judging from the painting, the texture of his skin is very smooth, and some details are also very real. I prefer that the murderer painted the deceased in a clean state."
With Bai Mo's professional judgment, Lu Wan continued: "The murderer's financial conditions are very good. I suspect that he took in this homeless man and gave him a particularly comfortable living environment, and then he would kill him when the time was right.
There is a big advantage in choosing homeless people. Such people rarely register at the police station, and no one will pay attention to their sudden disappearance. That's why Bai Mo couldn't find the information about the first deceased before. "
No wonder Lu Wan has always been so serious. She thought of this when she saw the deceased in the second painting. She had already concluded that this was a serial murder case!
Since the deceased in this painting really existed, it follows that the first deceased also existed, and was probably a tramp.
Bai Mo looked at the hand-painted painting with deep eyes and a serious expression on his face.
The manner of death of the deceased in the first painting and the second painting is different, which shows that the murderer may have customized different killing tools for different targets.
Thinking of the first painting, Bai Mo looked at Qin Youwei blankly, "What about the first painting?"
Qin Youwei also thought of the first painting. He shook his head slowly and smiled bitterly: "I'm thinking about it too, but I really can't think of the killing method in the first painting. I'm a forensic doctor. I really can't accept it. After a person's head is chopped off, his hands can still maintain their original position."
Lu Wan said: "What do you think of the deceased in the second painting? The limbs and head were chopped off at the same time. Logically speaking, wouldn't there be convulsions and the like, causing the position to shift?"
"What do you mean?" Qin Youwei vaguely grasped something, but couldn't tell.
Lu Wan looked at Bai Mo again, "If the body of the deceased is fixed, such as ropes and handcuffs, can you avoid these props when painting? Will it be affected?"
"Of course it won't be affected. Many models need to use tools when posing. Those tools will not appear in the paintings. This is every painter..." Bai Mo stopped, and he suddenly understood Understanding what Lu Wan meant, "The deceased was fixed by the murderer in other ways, so the deceased could maintain the posture desired by the murderer."
"That's right!" Lu Wan said, "And this also explains your doubt just now, why the murderer blurred the background of the painting, because there are props in the background that he used to fix the deceased."
At this moment, all the questions were explained clearly by Lu Wan.
Qin Youwei stared at the hand-painted face with a confused expression, "This painting is okay, the deceased is lying on the platform in a large font, and the limbs and head are well fixed, but I really can't think of the way he fixed the deceased in the first painting. "
"Maybe..." Bai Mo whispered, "I can try to draw it."
······
Under the dim light, Bai Mo crumpled up a piece of drawing paper and threw it on the ground.
This is Bai Mo's studio in the police force. The space is small but quiet. Bai Mo likes relatively dark lights, under which he has the strongest perception of color.
There are already more than a dozen paper balls on the ground, which shows that Bai Mo's progress is not ideal.
In the two previous cases, when Bai Mo led himself into the murderer, he could always feel what the murderer was thinking, so he took it for granted that he could perfectly interpret the murderer's inner world.
But this time, he failed.
Bai Mo was not in a hurry to continue with the next attempt. He stared at the white paper and fell into deep thought.
why? Why can't I feel his thoughts this time?
The door handle of the studio turned and the door was pushed open. Teng Jie appeared outside the door with a snack box in his hand.
Bai Mo glanced at Teng Jie and forced a forced smile, "Brother-in-law, why are you here?"
Teng Jie had his most classic smile on his face. He closed the door and came to Bai Mo. He put the lunch box on the table and said, "I'm here to help!"
"Help?" Bai Mo was stunned for a moment. Teng Jie probably meant to assist in the investigation. Bai Mo had never heard of the police force asking outsiders to assist in the investigation.
"Don't be surprised." Teng Jie could see Bai Mo's thoughts at a glance, "I have helped the police force twice in the past few years. As long as the procedures are complete, people outside the police force can be allowed to participate in some special cases."
This case is indeed special. If we look for real evidence, they don't even have the basis to open a case for investigation before it is confirmed that the deceased was murdered.
In other words, all their current investigations are based on their trust in Lu Wan and Lu Wan's statement that he has seen the second deceased.
"Are you here to help me draw tools?" Bai Mo asked.
Teng Jie pointed to the lunch box on the table, "It's already 1:30 in the afternoon. You have been working for four hours in a row. You need to replenish energy and take a short rest."
Seeing Teng Jie's attitude of "I won't tell you until you finish the meal," Bai Mo opened the lunch box without hesitation and devoured it.
This is Teng Jie, who always gives people a particularly comfortable feeling. He can gain the other party's trust with just a few moves.
For example, now, Bai Mo had an idea out of nowhere. With Teng Jie's help, he would be able to draw the murderer's criminal props.
Teng Jie said unhurriedly: "Lu Wan felt that the murderer had a very big imagination, otherwise he would not have been able to design so many murder props. I really have never lost when it comes to imagination, so she asked me to come over and help." .”
Teng Jie bent down and picked up a paper ball, opened it and took a look at it, then shook his head slightly and glanced at Bai Mo who was concentrating on eating. He said nothing.
After a while, Bai Mo pushed the clean lunch box in front of Teng Jie, indicating that he could start.
"I do cherish food." Teng Jie joked.
Seeing that Bai Mo had no reaction, Teng Jie retracted his intention to joke and said, "Do you feel that you have no way to start when drawing props and cannot find the murderer's ideas?"
"Yes!" Bai Mo responded quickly this time, "I drew many possibilities, but I always felt it wasn't quite right."
"Perhaps you were right once, but because you were not sure whether the murderer thought so, you denied yourself again. This is one of the most common psychological phenomena." Teng Jie said.
"Then what should I do?" Bai Mo looked like he was asking for advice humbly.
"It's very simple!" Teng Jie smiled, "Let's see what the murderer thinks."
