After reading the information, Jiang Chengyi took the coat that Lu Yan handed over and walked towards the entrance: "I have to arrest criminals these days, I'm very busy. When I'm not at home during the day, I ask Mrs. Liu and the others to come and accompany you. The driver is trained. I know how to adapt, and I can rest assured that they are here."

While talking, Lu Yan's cell phone rang. She clicked it and saw that it was a WeChat message from the director about the preliminary competition of the case competition. Before she could read it carefully, she patted Jiang Chengyi's chest and assured him, "You can go to work at ease, I will do the courseware at home. , This competition is very important, my senior brother entered the top ten in the country last year, this year is my turn, I have to prepare well, how can I lose my mentor."

Jiang Chengyi looked back at her.

As before, she is very demanding of herself, and knows that if she arranges her own life, she can often do the best thing without making a sound, so she pinches her cheek and emphasizes again and again: "You are the murderer who clearly distributed butterflies. The object of the sticker, if there are guests visiting at home, you must be more careful, and don't open the door unless I call you in advance."

"Know it."

"Oh." He pressed the elevator and remembered something, "Is this the second day?"

"What the next day." She wondered.

He half-smiled: "How many days are left?"

Only then did she react, hooking his neck and kissing him, deliberately teasing him: "It will take more than a week."

"So long?" He changed color.

She smirked: "Fool."

He laughed angrily: "Okay, Lu Yan. I'll take care of you when I come back tonight."

"How do you deal with my current physical condition?" She looked at him with confidence.

"Don't challenge me, Lu Yan." He put on a coat, his tone was light, and threatened her, "Anyway, there is a way."

She wasn't afraid, so she smiled and pushed him: "Let's go quickly, don't be late."

She smiled like a flower, and his heart seemed to be blown by a breeze, inexplicably sweet and drunk, and he couldn't move his legs.

Fortunately, the doorbell rang at this time. Lu Yan turned on the screen and saw that it was Mrs. Liu and the driver, busy pressing the door button.

After entering the elevator, Jiang Chengyi remembered something and said to Lu Yan, "I'll send you a few photos in a while, and you can help identify the person in the photos, and see if you can match the number of the woman eight years ago. Don't be too reluctant, just admit it if you can remember it, forget it if you really can't remember it."

Lu Yan knew that Jiang Chengyi was referring to the woman who looked a bit like a man in the central park back then. Out of confidence in her own memory, she nodded: "Okay."

Not long after Jiang Chengyi left, Mrs. Liu and the driver came up.

After entering the house, Mrs. Liu was busy cleaning the house, while the driver sat on the sofa and watched TV.

Lu Yan brought them tea, and talked with them for a while, then went back to her room to do her homework.

The sheets were changed early, the curtains were opened, the sunlight came in, and the air in the room was fresh and clean.

She first loaded the case screenshots taken by her mobile phone into the computer one by one, then pulled out a courseware template, and then sorted out the ideas in her mind, and began to make ppt.

This kind of case competition has extremely high requirements on the clinical thinking ability of young doctors. In just ten minutes, not only the courseware should be concise and clear, the analysis should be in-depth and thorough, but the selected cases should also include novelty and representativeness.

In other words, on the day of the competition, it is a mule or a horse, just pull it out for a walk and you will know.

After checking information, organizing language, and meticulously working for more than ten minutes, she finally remembered the WeChat message that Director Yu had forwarded to her, and hurriedly opened it.

[The National Young Anesthesiologist Case Competition is about to kick off. According to the requirements of the competition organizer, the preliminary competition is scheduled to be held in this city on the 15th of this month. At that time, ten outstanding cases will be selected by the judges to enter the national final. The venue of the preliminary competition will be determined. At the Hanlin Mountain Villa Hotel in this city, the time is 19:00 in the evening. There will be dinner and accommodation arrangements that night. The details of the competition are as follows...]

fifteenth? Isn't the preliminaries coming up in a few days?

don't know if the tutor was too busy or blindly confident in the students, so he only told her the time for the finals, and did not mention the time for the preliminary rounds at all.

But really can't blame the instructor. In the past, she has always been very interested in this kind of business competition. That is to say, she has encountered too many things during this time, so she did not take the initiative to follow up on it.

She opened the search engine and looked up "Hanlin Mountain Villa Hotel."

It is an old-fashioned five-star hotel, located in the suburbs, very close to the xx shop film and television base.

Such a rich and powerful competition organizer is really rare, no wonder it has such a great influence in the domestic medical field.

She replied a message to Director Yu: [I know, boss. 】

Just put down the phone, another message came in.

It is Jiang Chengyi.

Just a few words and a photo attached.

[Does the person in the photo have any impression? 】

She pulled down and saw that it was a full body photo of a woman in her twenties and thirties. The woman in the photo was dressed very outdated, with a black wavy head, a lavender dress, and white leather shoes with chunky heels.

Thanks to his tall, slender body and straight face, he was not overwhelmed by that outfit.

She stared at the photo and looked at it again and again, only to feel unfamiliar, but when she saw the woman's wavy head and leather shoes, there was a faint shadow, and she replied:

[The calf of the man I saw was much thicker than this man, not as delicate as this woman, um, who is this man? 】

[Teacher Zhou's wife Lin Chunmei. 】

【what? 】

[Lin Chunmei had a car accident ten years ago and was in a vegetative state from 2007 to 10 years, and died in September 2010]

She was stunned for a while before she realized what Jiang Chengyi meant: [You suspect that I saw Lin Chunmei eight years ago? But wasn't she already in a vegetative state eight years ago, how could she still run to the downtown park? 】

[Just now I called Ding Jing's father and confirmed that Ding Jing's aunt also worked in the electric power bureau. Ding Jing often went to the electric power bureau to play when she was a child. If the woman who came out of the rose garden at that time was Lin Chunmei, it is no wonder that Ding Jing would be scared. It's like that. Of course, everything can only be guessed at the moment. After all, Ding Jing has been killed and can no longer be confirmed. 】

Lu Yan was stunned for a while, then typed in: [Dr. Yu said that day that Deng Man was not the origin of all this, but Lin Chunmei, and the murderer likes to pretend to be a victim so much, could it be that the person I saw in the city center was the murderer who pretended to be Lin Chunmei ? 】

Jiang Chengyi didn't write any more, so he was probably busy.

She tried to post another.

[Jiang Chengyi, I can't remember exactly what that person looked like at the time, but that person really seemed to know you. 】

No reply.

Jiang Chengyi, Dr. Yu, and Lao Qin got into the police car.

"Team Jiang, let's go directly to Zhou Zhicheng's house, and then invite him to the bureau for questioning?" While the engine was starting, Lao Qin turned around.

"right."

"Zhou Zhicheng hasn't gone to work since he got sick, so he should be at home at this time."

"Xiao Zhou stared over there for a night. I asked him to go back to rest first. Now it's Cai Qi. Xiao Cai called just now and said that Zhou Zhicheng hasn't been out since last night."

When he stumbled, Lao Qin looked at Yu Zheng in the rearview mirror: "Dr. Yu, we have more and more clues. According to you, is it possible that Zhou Zhicheng is the murderer?"

Yu Zheng is still looking down at Jiang Chengyi's chat record with Lu Yan: "I read Zhou Zhicheng's resume and growth record in the morning, and also got a general understanding of Zhou Zhicheng's parents, I still maintain my original judgment - Zhou Zhicheng The possibility of being the murderer in this case is very small."

"But whether it was Deng Man back then or Ding Jing, who was killed this year, they are all closely related to Zhou Zhicheng. You see, Deng Man was the object of his teacher-student love, but he committed suicide by jumping into a river. I once secretly photographed his rendezvous with Deng Man. Eight years later, he was thrown into the water as a chrysalis. Also, Ding Jing's house on Yiyuan Road was pryed over. From the surveillance video in September and October Look, Zhou Zhicheng has appeared at the gate of the community several times, and he is very suspicious, not to mention that Zhou Zhicheng's appearance is similar to your profile, anyway, after thinking about it, I think Zhou Zhicheng is the murderer."

Compared with Lao Qin's confusion, Yu Zheng seemed very calm: "In 1992, the famous criminologists Holmes and Deburger divided different types of serial murderers according to their motives: 1. Fantasy type; 2. Task-oriented type; 3. Hedonic; 4. Vision/Dominance-oriented. From the criminal characteristics of this series of cases, the murderer is a mixed type of task-oriented and vision/dominant-oriented criminals. During the crime, the murderer did not sexually assault the four female victims Behavior and sexuality are dispensable in this case. The murderer's criminal impulse is only closely related to his eagerness to fulfill a sense of mission, and I suspect that the murderer's sense of mission has something to do with the criminal's childhood experiences. Just now, I was transferred to Zhou Zhicheng's medical report when he was in the First Affiliated Hospital. MRI and CT of his brain showed no signal changes in his prefrontal cortex, and the amygdala in his brain was also normal, of course. Physiological indicators are only one of the reference points. The most important thing is that, based on my preliminary understanding of Zhou Zhicheng and his growth environment, there are many differences between Zhou Zhicheng's personality characteristics and the criminal in this case. Even if Zhou Zhicheng committed a crime one day, he would also Most likely a thoughtful 'material-seeker', very different from the murderer's style in this case."

Old Qin scratched his hair and smiled bitterly: "I don't understand very much, but Doctor, according to you, the possibility of Zhou Zhicheng being the murderer is relatively small, but at least he should know something about what happened back then. Look, his teachers and students Deng Man, the love interest, died inexplicably and was imitated by the murderer many years later. His wife had an accident at a young age, and I always felt that Zhou Zhicheng probably knew the murderer without knowing it."

"Your inference is very likely to be close to the truth, so your team Jiang decided to change it from a suspect to protecting a witness, and plan to go there to pick up someone in person. I agree with your team Jiang very much, even if the murderer is not a student of No. 7 Middle School, You should also get to know Zhou Zhicheng."

Jiang Chengyi took the mobile phone returned by Dr. Yu, dialed it to Cai Qi, and asked, "Is Zhou Zhicheng still at home?"

"Yes." The other party replied, "A few days ago, he would go out for a walk, buy things, and visit neighbors every day, but he didn't go out much these days."

Jiang Chengyi: "We are almost downstairs. You go up and knock on the door. If he refuses to open the door, you will act according to the circumstances and ensure his personal safety no matter what."

"Got it, Team Jiang."

The group arrived downstairs, and just as they were about to go upstairs, Jiang Chengyi's phone rang.

Cai Qi's voice was urgent: "Team Jiang, Zhou Zhicheng hanged himself."

Jiang Chengyi's expression changed, and he rushed to the second floor where Zhou Zhicheng lived in three steps.

"What happened?" Lao Qin also followed Jiang Chengyi upstairs.

Yu Zheng only felt that the figure in front of him flickered, and the wind disappeared into the stairwell.

When he climbed upstairs and entered the room, his heart jumped, and he saw Jiang Chengyi squatting next to a middle-aged man doing chest compressions, his face was pale, and his cpr technique was very professional. The frequency is about 105 times, and the depth and location are also fully qualified.

The name on the ground should be Zhou Zhicheng, and there are traces of mechanical trauma on his neck.

120 should have already been called, and Lao Qin is searching the house.

The young police officer named Cai Qi knelt beside his head and said at a loss: "I saw Zhou Zhicheng feeding birds on the balcony in the morning, but I didn't see any suicidal tendencies at all, and no one had ever entered or left Zhou's house, it was Zhou Zhicheng. I just received a call, and the call lasted for forty minutes. I don't know if his suicide has anything to do with this kind of call,"

"Fucked by the murderer again." Jiang Chengyi gritted his teeth and said, "The suffocation time is not long, let's save people first!"
