"You don't know?" Mingshu tapped on the photo on the left, "Then why is there your skin tissue in her nails?"
Wang Zheng's eyes widened immediately, "I, my what?"
Mingshu sighed, "Do I need to repeat it? Your skin tissue is in the victim's nails. Otherwise, why would I invite you here?"
Wang Zheng said: "I thought you came to me for the mistakes I made before! I really don't know this person! I haven't seen her at all!"
People can lie, but physical evidence doesn't.
Mingshu's gaze shifted from Wang Zheng's face to Wang Zheng's arm, "Take off your shirt."
Wang Zheng froze on the interrogation chair.
Mingshu added: "Or you can roll up your sleeves, as long as you can expose both arms."
There was obvious fear in Wang Zheng's eyes. After hesitating for a while, he took off the takeaway clothes and rolled up the sleeves of the T-shirt inside.
Mingshu saw at a glance that there was a scratch that was no longer obvious on Wang Zheng's right arm.
Mingshu raised his chin, "What is that?"
Wang Zheng looked down, "This is... ah! I remembered, it was caught by a woman!"
Mingshu picked up the photo on the left, "This woman."
Wang Zheng hurriedly closed his eyes, not daring to look at the pictures of the corpse.
A series of reactions after Wang Zheng was brought to the serious crime team has made Mingshu think that he may not be the murderer, but it is a fact that his skin tissue appears in the victim's nails.
Wang Zheng said that he did not know the victim, so under what circumstances would the victim arrest Wang Zheng
Mingshu said, "Remember carefully, when did this scratch appear? Why did this woman grab you?"
Wang Zheng was restless, "Just a few days ago, we were all on the bus, and the car was very crowded, she was standing next to me, wearing a white sports suit. I don't know what happened, the car suddenly braked suddenly, she He didn't stand firm and grabbed my arm all of a sudden. I'm a man, and I've been used to doing rough and tiring work for a long time, so I don't feel much pain. You don't even know that I have scratches here."
"Wait." Mingshu said, "Although the temperature hasn't cooled down a few days ago, it's no longer the season to wear short sleeves. How come your upper arms are still exposed?"
"I just finished working at the construction site!" Wang Zheng said, "Is there any surveillance on the car? She and I are standing near the back door. If you don't believe me, you can check the surveillance!"
Mingshu asked, "Which bus did you take? When did you get on and off?"
Wang Zheng said: "No. 308, the construction site is night work. I finish work at 9:00 in the morning, and I will start delivery at noon. I think... It should be around 9:30 when I get on the bus, and no later than 10:00 when I get off the bus."
Mingshu said, "Go, verify Wang Zheng's words."
The bus and subway systems in Dongye City have long been equipped with monitoring. As Wang Zheng said, the victim's fingernails had his skin tissue in it. It was indeed because of an emergency brake on the 308 bus on October 13.
Yi Fei has rushed back to the serious crime team and informed Mingshu of his judgment: "Although Wang Zheng has a hidden illness, after he was released from prison, he has been actively looking for a job and taking care of his elderly mother. I don't think he fits the murderer's psychological characteristics. "
Mingshu is watching the surveillance, "He is indeed not the murderer, but his clue is very important. The identities of the two victims can be determined immediately."
Bus No. 308 runs from Heting Station in the south of Dongye City to Tianxing West Road Station in the northwestern suburbs. The route is very long, with as many as 37 stops. On the way, it passes through two commercial centers, a railway station, and four middle schools. And Dongye University Zijiao Campus.
Surveillance at the front door of the bus showed that the girl who scratched Wang Zheng got on the bus at the station near the Zijiao campus, with a Nikon SLR hanging on her chest, while her companion was a man wearing red sportswear and black sports. with shoes.
Their clothing features are in line with Wu Hao's description. Judging from their age and dress, they are likely to be students from the Zijiao campus.
The two girls got off the bus at the terminal, Tianxing West Road Station, and then appeared on the roadside public surveillance, and soon got into a red Ford sedan.
Mingshu explained the task, "Find the female student who has been missing for more than four days in the Zijiao campus and find the owner of this Ford."
The general scope has been drawn, and the identity of the victim is quickly determined—
Lv Chen, 24 years old, from Helian County, Dongye City;
Zhao Siyan, 24 years old, from Los Angeles.
They corresponded to the No. 1 victim and No. 2 victim that Xing Mu marked at the scene, namely "upper" and "lower".
Both of them are second-year graduate students of the School of Public Administration at Zijiao Campus of Dongye University. They share the same dormitory and have the same tutor.
The postgraduate dormitory was newly built a few years ago. The hardware conditions are much better than that of the undergraduate dormitory. There are only four people in one room, and air conditioning, hot water, and broadband are readily available.
Knowing that the two roommates had been killed four days ago, Yang Le was speechless, and another girl in the same bed, Zhan Li, was speechless.
Mingshu saw shock, fear, and unease in their eyes, but the sadness was minimal, almost negligible.
"Lv Chen and Zhao Siyan didn't go back to the dormitory for four days, don't you feel surprised at all?" Mingshu asked.
"We, we have a very normal relationship." Zhan Li said with a pale face, "and they used to spend the night outside often and never greeted me. I really didn't know they were dead."
Yang Le hesitantly said, "Although I share a dormitory with Lu Chen and Zhao Siyan, I am not classmates with them, and we are not familiar with them. I am from the School of Chemical Engineering, and I have been sleeping in the laboratory these days."
Mingshu has asked the technical team to adjust the surveillance near the dormitory, check the communication records of the two victims, and arranged for Fang Yuanhang and other team members to investigate the relationship between Lv Chen and Zhao Siyan in detail, while he continued to question Yang Le and Zhan Li.
"You said they often spend the night outside. Do you know where they go?" Mingshu looked at Zhan Li, "You and them are not only roommates, but also classmates in the same major. What you know about them , it should be deeper than Yang Le, right?"
"Bars and clubs." Zhan Li's forehead was sweaty. "They were not from our school before, they were admitted from other schools."
When he said this, Zhan Li frowned, a little disdain and impatience in his expression.
Dongye University is a first-class university. Zhan Li used "we" and "them" to distinguish himself from Lu and Zhao. Mingshu could see that, as a graduate student at the school, Zhan Li did not look down on Lu and Zhao who came from the school. eye.
"Are they going to the nightclub for fun, or..." Mingshu deliberately didn't finish.
"They are doing part-time jobs," Zhan Li said.
The two female graduate students often do not go home at night and work part-time in the nightclub, which is really reminiscent.
Mingshu asked again: "When did it start? Which bars and clubs are there?"
Zhan Li shook his head: "I didn't ask. In terms of time, I remember it was the next semester of the first grade."
Mingshu said, "Are Lu Chen and Zhao Siyan a good relationship?"
"They are classmates in college, not like us." Zhan Li once again showed that superior look.
"That is to say, they always stay together and have their own small circles." Mingshu asked: "In school, who has a good relationship with them?"
Zhan Li said several names, "They were all admitted by graduate students."
Mingshu made records one by one, and then asked, "What about outside school? Let's just say the last month, have anyone outside of school contacted them?"
Zhan Li has calmed down from the surprise of learning that his roommate is dead, and his expression gradually became indifferent, "I have my own homework and projects, and who they associate with has nothing to do with me."
Yang Le told Mingshu alone that Zhan Li and Lu Chen and Zhao Siyan had many conflicts. He was not in the same major with them and had no competition with them, but living in the same dormitory made him feel uncomfortable, like a sandwich cookie.
Mingshu asked, "Before Lv Chen and Zhao Siyan left school, did you find anything unusual?"
Yang Le recalled, "I stayed up all night in the laboratory that day and planned to go back to the dormitory to catch up on sleep. It was already class time, I thought there was no one in the dormitory, but Lu Chen and Zhao Siyan were both there. They wanted to go out and they called me. with them."
Mingshu said, "Didn't you say that you are not familiar with each other?"
Yang Le said quickly: "Actually, it's mainly because of Zhan Li. They don't have a good relationship with Zhan Li, and Zhan Li has a very strong personality. When Zhan Li was there, the four of us didn't talk much."
Mingshu said, "When Zhan Li is away, do you and Lu Chen and Zhao Siyan occasionally chat?"
"Yeah." Yang Le said, "Zhao Siyan also showed me her camera. She said that she bought it with money from her part-time job. It cost more than 20,000 yuan. She wanted to take it out to take pictures of ginkgo leaves. They said, ask me out next time you go out to play."
Speaking of this, Yang Le's shoulders trembled, and he fell into a very fearful mood, "If I go with them, am I also killed?"
Mingshu asked back, "Have you offended someone, or been entangled by someone?"
Yang Le shook his head blankly, "I spend most of my time at school and have a good relationship with my classmates and mentors. I basically haven't had contact with outsiders."
"Have they been entangled by anyone?"
"I… I don't know."
Mingshu said, "Then let me ask you another question. When Lv Chen and Zhao Siyan left the dormitory, were they in high spirits to enjoy the autumn?"
Yang Le said seriously: "Yes."
At noon, Mingshu convened the team members for a case review meeting.
"The bar where Lv Chen and Zhao Siyan are part-timers has been found out." Xu Chun said, "It's on a night market street in Nancheng District, called 'Lin Shen Sees the Deer'. On the surface, it looks like a very ordinary bar, with a minimum per capita consumption of 120 yuan. , Is there anything wrong with the bar itself, and whether Lu and Zhao got into any trouble there, we must continue to investigate."
Mingshu said, "What about communication and monitoring?"
Zhou Yuan said: "On the day Lv Chen and Zhao Siyan were killed, three days later, they only contacted their family members and classmates from other places. There were three strange calls on Lv Chen's mobile phone. It has been verified that they were couriers and takeaways. Outside the dormitory The surveillance caught them every day, and when they left on October 13, there was no significant difference in their behavior."
Mingshu said: "It means that they have not been in contact with suspicious people recently... How about pushing the time forward?"
Zhou Yuan looked serious, "Zhao Siyan frequently called a number more than a month ago. After real-name inquiry, this person is He Yi, male, 34 years old, a civil servant, working in the Municipal Cultural Bureau."
"A month ago?" Mingshu asked, "Is there any contact recently?"
Zhou Yuan shook his head, "Zhao Siyan blocked him."
"Pull black?" Mingshu said, "Then this person must be found."
Zhou Yuan said: "Understood."
Mingshu thought for a while, then turned to Yi Fei and Fang Yuanhang, "Where are you?"
Fang Yuanhang said first, "Lv Chen is very popular in the School of Public Administration. There are not many student activities for graduate students, and many people are reluctant to participate, but Lv Chen has a generous personality and participates in everything, although he did not study at Dongye University as an undergraduate. , but soon after entering the school, I became familiar with most of my classmates."
Mingshu said: "The 'most' include students who are guaranteed by the school?"
Fang Yuanhang said, "Yes."
Mingshu writes and draws in a notebook. What Fang Yuanhang learned was obviously different from what Zhan Li said, so was Zhan Li lying, or was most of the students in the School of Public Administration lying
Ming Shu's pen landed on Zhan Li's name and tickled it.
"Lu Chen's grades are very good, and her tutor's evaluation of her is also very high." Fang Yuanhang continued: "Zhao Siyan is a little worse, and their majors are ranked below the middle in the comprehensive assessment of the first grade. Let me put it this way, take us to the top. As an example of a case, Lv Chen is the kind of student who is very talented and has good grades even if he doesn't study much. Zhao Siyan is a little less talented, but not too diligent. pulled."
"Their family conditions are not bad." Yi Fei added: "Zhao Siyan's home is in Luocheng, middle-class, her parents are both in business, and she has only one daughter. Although Lv Chen's hometown is in the county, she has been living In the city, my parents are also in business, and there is a married sister on it."
Mingshu said: "Then they don't actually need to go to night clubs to do part-time jobs."
"In my judgment, maybe it's just something fresh." Yi Fei said, "Or maybe you want to support yourself."
Mingshu stared at the contents of the notebook for a long time, "The social relationship between Zhao Siyan and Lu Chen seems to be relatively simple now. From the analysis of the clues they have, it is likely that they went to Qiyue Mountain on the 13th for a temporary purpose, and they were not influenced by anyone. They don't know that they have been followed, and they probably don't know who this person is."
Xu Chun said, "Is this a random case? A psychopath and a murderer who has a special need for sex arbitrarily arrests two girls and commits the crime?"
"If that's the case, then the murderer is very likely... No, the murderer will definitely commit the crime again." Yi Fei was a little worried, "The death of Lv Chen and Zhao Siyan shows that the murderer was a 'expert', he - I assume he was a man - in Before the '1013 case', he must have murdered women."
"We have a lot of clues now." Mingshu stood up and threw the notebook on the table.
He has the habit of recording at any time, but after recording, he prefers to analyze the case away from the notebook.
"'Lin Shen sees a deer' is a line. Schools and bars are the most important social places for Lu Chen and Zhao Siyan. Compared with schools, bars are much more complicated and mixed up. Did the murderer target them in 'Lin Shen sees a deer'? ?" Mingshu said, "That civil servant named 'He Yi' may be a frequent visitor to 'Lin Shen sees a deer'."
Xu Chun said, "I will follow this line."
"Well." Mingshu added: "The victims died tragically, but the murderers have more 'appreciation' for them than hatred."
Yi Fei agreed, "That's right, if the murder is due to hatred, under those conditions, the murderer will most likely destroy the body. But I'm thinking, in this case, the murderer is probably not someone in their social circle at all."
Mingshu said: "After the investigation of their interpersonal relationships is over, this question will come to a conclusion."
Fang Yuanhang raised his hand, "So, isn't that Wujie in Haijing Temple also motivated? As long as he is psychopathic, he can do anything."
Mingshu smiled at his apprentice, "If you can't let it go, go check it out, just like the previous case."
Fang Yuanhang shrugged his shoulders and said in a low voice, "I'm your competent officer now, right?"
Mingshu asked Xiao Man again, "Can you tell where the ten nails were produced and where they were sold?"
"It's all ordinary building materials. Judging from the degree of rust, it's at least ten years ago." Xiao Man said: "We took it to the construction site and the building materials market to identify it to experts, and no construction site is still using this kind of material. Nails have long been eliminated in the building materials market."
Fang Yuanhang said, "How did the murderer get this nail? Wait! Since it is something that has been around for such a long time, maybe a lot of people have used it!"
Xiao Man shook his head, "I have checked each one in detail, and only extracted the DNA information of the victim."
Mingshu asked Zhou Man: "Is it possible to use technical means to lock the location of Lu and Zhao's mobile phones?"
Zhou Man said, "No, the murderer has already destroyed the phone."
Mingshu rested his hands on the table, and this posture made his eyes look particularly sharp, "This is a murder case against a young woman. The murderer can insert a sharp object into the temporal bone of the victim when he is awake, which shows that he is cruel by nature, and he is skilled. Yes. Yi team is right. Such a person should have committed crimes in the past, either in other provinces or cities, or in Dongye City, and the body of the victim has not been found. If we do not arrest this time Live with him, and soon he will be committing crimes again."
"On the one hand, screening the disappearance cases in the city, finding out women who are similar in age to Lu and Zhao, and focusing on college students and graduate students with outstanding appearance. On the other hand..." Mingshu paused, "I'm going to apply Investigate similar cases across the country. However, the case of Lu and Zhao happened in Dongye City, and it is the responsibility of our Dongye police to find the murderer. Now that the holiday has just passed, our autumn tour has been in vain, but everyone must cheer up, Be sure to find the murderer before he commits the crime again!"
With the cooperation of the traffic police department, the team members who tracked the Ford car identified the owner of the car.
The owner's name is Xiong Hanqiang, 45 years old, from Shouquan Town.
When the police arrived at his home, his wife was crying loudly, "Xiong Huqiang, you don't want our home anymore?"
Criminal Investigation Bureau.
Mingshu originally wanted to contact the special operations team himself, but after thinking about it, he decided to hand it over to Xiao Yuan.
When he went upstairs, he saw Liang Zhao again, but this time Liang Zhao did not see him.
Liang Zhao's face was very gloomy, and he was hurriedly walking to the other side of the stairs with two opaque pockets in his hands.
Mingshu subconsciously avoided the shadows, and only came out of the shadows when Liang Zhao had gone downstairs.
There was a slight noise behind him, and Mingshu turned around abruptly.
I saw Li Ju was standing a few steps away from him and smiled: "Ming team, what are you looking at so focused on?"
