As soon as he saw Lu Yan, Yu Zheng smiled and stretched out his hand: "Miss Lu, you don't remember me, but I still remember you. Last year, your tutor gave a lecture at the physiology conference, and you were the secretary next to you. The courseware for that class was well done. First-class, I have a deep memory. Speaking of which, the basic disciplines of anesthesia and criminal psychology are related to physiology, and you and I are half peers.”
No wonder it looks so familiar.
She hurriedly shook hands with Yu Zheng: "Hello, Dr. Yu."
It's strange, her memory should be focused on certain aspects. She can't remember Dr. Yu's name, but she can remember the content of the last lecture by her tutor.
I remember that the topic of the instructor was "The Arousal Mechanism of the Cerebral Cortex", a very basic class. At that time, it seemed that Dr. Yu came to discuss with the instructor for a long time after the class, and the topic always revolved around the autonomic nervous system response of psychopaths. .
If I remember correctly, this person is a prodigy in the field of criminal psychology.
Jiang Chengyi said: "Dr. Yu, since we have time in the evening, we might as well have a meal at the Chinese restaurant in the hotel opposite."
Yu Zheng echoed: "That's what it means."
After leaving the branch, the three went to the famous Chinese restaurant in the opposite hotel to take a seat. The waiter quietly approached and presented the menu.
Jiang Chengyi took the menu, leaned back on the chair, and started ordering.
Lu Yan took off her jacket, remembered the phone call just now, and wanted to ask how Jiang Chengyi responded to Jiang's mother. Considering that Yu Zheng was beside her, she didn't ask.
The restaurant is very quiet, and the light music flows into the ears, giving people a wonderful feeling of being groped for no reason.
In the sound of music, Yu Zheng looked at Lu Yan, and Lu Yan also looked at Yu Zheng. After a while, seeing that Yu Zheng had no intention of opening her mouth, she smiled apologetically and took out the notes she made earlier to browse.
Yu Zheng crossed his arms with his arms, his eyes stopped for a moment on the notes in Lu Yan's notebook, then suddenly lit up, and looked at Lu Yan with a smile: "Miss Lu, I looked through Deng Man's file and noticed that someone had been there for seven consecutive years. I sent an anonymous letter to the Anshan District Bureau. Some time ago, when I met someone who was pretending to be Deng Man, the witness happened to be named Lu. I remember that the witness and Deng Man were very close friends in high school. Let me take the liberty of Ask, is the witness who wrote the anonymous letter Miss Lu?"
Jiang Chengyi was still looking at the menu, and after hearing this, he looked up at Yu Zheng.
Lu Yan was startled.
Yu Zheng's eyes shot straight into her heart like a ray of sunshine through the dark jungle.
After looking at each other for a while, her taut back slowly loosened, her eyelashes slowly lowered, she smiled and admitted frankly: "Yes."
There was an illusion when speaking, the other party seemed to open a wound that had been scabbed for a long time, cut off the rotten flesh, and let new flesh grow.
Jiang Chengyi was secretly relieved when he saw that Lu Yan was able to deal with it with ease.
Yu Zheng cast an appreciative look: "Ms. Lu, after you sent an anonymous letter, the police intervened twice in Deng Man's case, but unfortunately, both investigations ruled out the possibility of Deng Man's homicide. Even after eight years Later, despite the fact that the police had so many clues, they still could not clarify the truth of the year, which shows how complicated the case was. However, as a friend of Deng Man, Miss Lu never gave up on investigating this matter. I am deeply impressed. Miss Lu, from your education and resume, your learning and memory skills are very good, but the most outstanding one should be your observation ability. Now we have reached the white-hot stage to find the murderer, let me A sudden request—"
Lu Yan looked at Jiang Chengyi sideways, and soon saw the default attitude in his eyes. It was obvious that Jiang Chengyi recognized Yu Zheng's professional ability and quality, so she relaxed and said, "Dr. Yu, please say ."
"Team Jiang told me a part of what happened back then, but looking back on the whole case, I still want to use Miss Lu's observation ability to take me back to Class 7 of Middle School 6 eight years ago, using your memory and your eyes. And feel, help me to think back, what do you think about the then head teacher, Teacher Zhou."
Lu Yan closed her eyes and thought back, which was also strange. Every time she thought of Teacher Zhou, the most prominent scene was the scene where he was standing on the podium in a white shirt.
The sun was shining brightly, with tiny dust floating in the light. Teacher Zhou's voice was low and mellow, echoing in the classroom one after another.
She slowly recalled: "Mr. Zhou is a very patient teacher with students. He has a mild temper and treats students equally. Because of his outstanding professional ability, he is rated as an excellent teacher every year. He teaches physics, and many difficult problems are discussed by him. As soon as he explained it, it became easy to start, so the students admired him very much at the time. I remember that Deng Man did not do well in physics when he was in the first and second year of high school, and then gradually got better under the guidance of Teacher Zhou. "
Yu Zheng's voice became soft: "Did Mr. Zhou feel emotionally unstable during the three years of teaching in high school?"
Lu Yan closed her eyes and thought for a long time: "No, Teacher Zhou is always in a stable mood."
"A person who is good at disguising." Yu Zheng took out a small notebook and a pen from his arms and began to write and draw.
"During Zhou Zhicheng's life, he encountered at least three major emotional setbacks. The first was when his wife had an accidental miscarriage in 2000. The second was when his wife was in a car accident, after which his wife became a vegetable and lay in bed for three years. The third time was the death of your wife. Of course, the first incident happened when you were nine years old, far from school age, and the third incident happened in September 2010, when you had graduated and left school—"
He changed the topic and asked Jiang Chengyi: "Jiang team, when you introduced the information of Zhou Zhicheng's wife Lin Chunmei just now, I found that her physique was very similar to the later victims, both 166-167, about 50kg, and her appearance was also very beautiful. I don’t know if you have checked—well, I mean, was Lin Chunmei’s cause of miscarriage at the time, was it a natural miscarriage, or was there some other external factor?”
Jiang Chengyi said: "We are investigating, but Lin Chunmei's parents went back to their hometown to visit relatives. They are not in the city at the moment. Zhou Zhicheng is here... Until we get further clues, we don't want to panic. The news we heard from the neighbors is that Lin Chunmei was with him during his lifetime. Like her parents, her personality is more aggressive and domineering, not easy to get along with, and in terms of popularity, she is far less good than her husband Zhou Zhicheng."
Yu Zheng nodded, with some regrets: "If Lin Chunmei is greatly influenced by her family, it is very likely that she is a strong personality like his parents. Even if she has children, she may not be a qualified mother. But Zhou Zhicheng's personality There are some discrepancies between the portrait and the portrait of the criminal, no matter what aspect... they don't quite match, it would be great if you could know about Zhou Zhicheng's childhood experiences."
He crossed his fingers to his lips and remained silent for a long time, the usual relaxed smile on his face was gone, replaced by deep confusion.
After a while, he looked up at Jiang Chengyi: "Team Jiang, are you sure Zhou Zhicheng has no children?"
"According to the current information, no." Jiang Chengyi knew that Lu Yan was hungry, and as soon as the dishes came up, he scooped up the soup for Lu Yan. "Also, even if Zhou Zhicheng has children, he married in 1997, and his son At most, they were born that year, and grow up to 19-20 years old this year, but the murderers in this series of cases can move between city b and city s, buy hacking software that invades websites, transfer corpses, satisfy the wishes of victims, arrange In the field, these all require strong economic power. Young people in their 20s may have criminal motives, but they are unlikely to have these practical conditions.”
Yu Zheng patted his forehead and showed a self-deprecating smile: "Oh, I was too eager for success. However, when I was looking at Lin Chunmei's photo just now, I suddenly had an inspiration, and I always felt that Deng Man was not the origin of all this, Lin Chunmei That's right, but from the clues I have so far, there are many places that contradict my inferences."
He pondered for a while: "Team Jiang, I agree with your practice of focusing your investigation on the people and things of No. 7 Middle School. In any case, I will wait for your further investigation. In addition, I would like to add, I am very confident in my professional ability, and I believe that there are some key links missing here.”
Jiang Chengyi's movements stagnated for a while, and after thinking for a few seconds, he nodded.
After the meal, Yu Zheng talked about his happiness, and until he got into the car, he was still discussing with the two about the criminal's brain's shortcomings in controlling emotions and behavior and the pcl-r scale.
After seeing Yu Zheng away, the two got into the car, Jiang Chengyi said to Lu Yan, "My mother is still waiting for you at Yuheng Plaza, let's go."
Before Lu Yan answered, the phone rang, and it really was Mother Jiang.
"Yanyan, when are you coming over? This season's chanel is so powerful, there are many styles suitable for young ladies, both elegant and generous. And your good friend Miss Tang, auntie likes to get along with young people the most, If she is free, come and play together."
Lu Yan glanced at Jiang Chengyi, and seeing that he didn't object, she said, "Okay, auntie, we've already come, I'll try to call Tang Jie."
Soon we arrived at Hengyu Plaza.
Tang Jie seemed to be shopping at a nearby mall and arrived earlier than her.
All of a sudden, two heavyweight customers came, and Sa hurriedly led them into the VIP room inside.
Jiang Chengyi was bored and sat on the single sofa to play with his mobile phone.
Mother Jiang was very dissatisfied when she saw that Lu Yan only offered her and Tang Jie a reference, but she didn't try any clothes: "Don't save money for Jiang Chengyi, his salary is low, but the shares his grandfather left him every year. The dividends are very considerable, Hao Yanyan, as long as you like these clothes, you can buy them."
Before he finished speaking, Jiang Chengyi still frowned at the information sent by Lao Qin, and at the same time took out the wallet from his arms, took out one of the cards, and handed it to sa next to him.
Tang Jie's stomach almost hurt from laughing, so she secretly pulled Lu Yan aside: "Jiang Chengyi hasn't changed at all. He is still as generous to you as he was back then, but I said, your mother-in-law is really a wonderful person."
