There was silence in the office. Everyone, including Bai Yonghui, looked at Lu Wan with wide eyes.
In the eyes of others, Lu Wan's leap was too big. His inference at the beginning was fine, but later he directly said that the first victim was someone close to the murderer. It was too hard for the police in these small cities to accept.
Bai Yonghui took out a cigarette and put it in his mouth, and Zeng Hao on the side quickly lit it for him.
"Huh -" spitting out a thick white mist, Bai Yonghui swallowed the doubts in his heart. He knew that Lu Wan could not be questioned on this occasion. This was the prestige of a captain.
Lu Wan slowly shook her head, "It can't be a girlfriend. His desire to control and conquer is too strong. He won't have a girlfriend, so the probability of being a relative is greater! If it's an older sister or younger sister, then they are not with their parents. They live together, but his financial ability is not enough to support him in having another house, but he lives with his relatives, and his parents should be gone."
"Zeng Hao!" Lu Wan said sternly, "Contact the household registration office of each police station and screen people between the ages of 20 and 30 according to the range I just mentioned, who have relatives of the same generation, but whose parents are no longer alive."
Then, Lu Wan arranged for Sun Xiaokai to try to locate Tang Xueqiong's mobile phone.
The murderer's financial situation is very poor and he will definitely sell the deceased's mobile phone. As long as the mobile phone is turned on again, they can determine the murderer's location.
Finally, Lu Wan asked Peng Yuetao to follow Tang Xueqiong's route from get off work and continue to look for witnesses.
After arranging work, Lu Wan was about to call it quits when Bai Yonghui suddenly raised his hand.
Bai Yonghui looked at Bai Mo, who was silent the whole time, "Bai Mo, what do you think?"
Everyone looked at Bai Mo, which made Bai Mo feel uneasy. He scratched his head and said awkwardly: "What I said seems to have little to do with the case."
"Speak out boldly!" Bai Yonghui encouraged.
Maybe others think that Bai Yonghui is deliberately giving Bai Mo a chance to perform. Only Bai Yonghui knows clearly that Bai Mo will definitely be able to discover things that others cannot see, because Bai Mo's vision is different from ordinary people.
Over the years, Bai Mo has been studying painting abroad, but Bai Yonghui always asks Bai Mo to read some books related to criminal investigation. The contents of their weekly video calls are almost all cases in the books. Bai Mo's interpretations are always very unique. Although it is not a traditional route, it can still point to the murderer.
After Bai Yonghui discovered that Bai Mo had a talent for solving crimes, he began to plan for Bai Mo to become a criminal policeman. Only Bai Yonghui knew that Bai Mo could not only draw.
Of course, Bai Mo has never been exposed to criminal cases abroad, and all his ideas are theories. Today, Bai Yonghui finally has a chance to verify them.
Bai Mo first glanced at Lu Wan, who was looking at him expectantly.
"Uncle Qin, please bring up the photo of the deceased's back." Bai Mo said.
Qin Youwei cooperated and pulled out the photo of the deceased's back. Bai Mo pointed at the photo and said, "Don't you think it's weird?"
A glint flashed in Lu Wan's eyes, "No injuries?"
"Yes!" Bai Mo's voice was slightly excited. He never expected that Lu Wan would discover this right away, "There were so many heavy blow injuries on the face, chest, and abdomen of the deceased, but why was there no injury at all on the back?"
Lu Wan frowned, folded her arms and looked at the photo carefully, "Go on."
"There are many injuries on the front of the deceased. According to everyone's inference, they were caused by the murderer in order to control the deceased. Have you ever thought about what the murderer's purpose was, was it a simple murder or an invasion?" Bai Mo said.
This question really stopped Lu Wan. She thought about it and said, "Isn't the probability of invasion greater?"
"No, just for the purpose of infringement." Bai Mo said firmly.
Lu Wan was stunned for a moment. In fact, she also believed that the murderer's ultimate goal was to invade, but she could not provide direct evidence.
"Judging from the injuries the murderer caused to the deceased, he was very powerful, but he perfectly avoided the deceased's back every time he hit him, and made sure that the deceased's back was not injured when he attacked the front of the deceased. ." Bai Mo continued.
Peng Yuetao, who is good at fighting, analyzed: "This is easy to do. You can pull the hair, shoulders or wrists of the deceased when attacking."
Bai Mo nodded, "Especially the heavy blow to the deceased's abdomen that caused internal bleeding. The impact still did not hit the deceased's back. What does it mean? It means that the murderer wanted to ensure that the deceased's back was perfect, Sister Lu Wan, You said that murderers sometimes have criteria for choosing their targets."
This is what Lu Wan said to Bai Mo at the crime scene.
Lu Wan suddenly realized, "The murderer has a special obsession with women's backs?"
"I think so." Bai Mo was very happy that someone could understand his thoughts. If it were Bai Yonghui, he would definitely criticize him for saying some unreasonable things.
Bai Mo said: "The injuries on the front of the deceased were all caused during his lifetime. If I were the murderer, and you asked me to assault a panda with bruises on his chest, I really couldn't do it. Considering the deceased at the crime scene, The position of kneeling beside the toilet, I think that is also the position of the murderer when he violated the deceased. For him, all he needed was a perfect back."
"But how did the murderer know that the deceased's back met his standards?" Chen Xiaoxiao couldn't help but ask, looking at Bai Mo with a hint of surprise in his eyes.
Some may find this clue irrelevant, but to those who study criminal psychology, this particular quirk is what marks a killer.
Bai Mo shook his head, "I'm also very surprised. I saw all the clothes of the deceased. The deceased's clothes were very traditional. There was only one skirt, mostly jeans, and the top didn't even expose the navel. Logically speaking, the murderer couldn't have had the opportunity to see it. to the back of the deceased. But this may also be the basis for us to identify the murderer."
Chen Xiaoxiao showed a wry smile. It turned out that Bai Mo was really investigating the case seriously in the morning. At that time, he suspected that the murderer chose the victim's label for the back, so he checked all the clothes of the deceased.
Photos of Tang Xueqiong's clothes flashed through Lu Wan's mind, and she nodded in agreement, "The deceased was indeed dressed very conservatively, without any sexy clothes or stockings. That kind of dress would hardly attract criminals, so the murderer must have seen Tang Xueqiong. A back that fits his label!”
"It seems that we have to add another direction of investigation." Lu Wan said, "The murderer had the opportunity to see the deceased's back. Xiaoxiao, you and Bai Mo go to the clothing company where the deceased was located to investigate and see if anyone has any A chance to see the dead man’s back.”
Chen Xiaoxiao nodded in agreement.
"There is one more person to investigate." Bai Mo's voice attracted everyone's attention again, "Tang Xueqiong's boyfriend Song Jingliang, he slept with Tang Xueqiong. We need to know if he has a special habit of making videos."
