A university professor with a doctorate who teaches and educates people, and an engineer of the soul of students, was brutally killed in the suburbs, which is a big loss for Jiangcheng, Dongzhou, and even the whole country.

Who knows if Cao Yuning hadn't been killed, how many graduate students and how many PhDs would he have been able to train in the future?

"It's a shame." Shi Xin also sighed: "If you follow the logic of vendetta, how do you think that this Cao Yuning doesn't look like he can make enemies with people, and he was still studying for graduate school ten years ago, right?" ”

Chen Yi and Zhao Qiming did not speak again.

Now it is not known what the hell is going on in this case, everything is speculation.

The only thing that can be done is to collect as many clues as possible step by step, and then try to deduce from the clues collected to determine the direction of the greater likelihood.

Soon, Cao Yuning's home arrived, and several people knocked on the door.

After waiting for the door to open for a while, several people looked down at the same time, and standing in front of them was a five or six-year-old boy.

The little boy blinked his big innocent eyes, and his immature voice sounded: "Uncle, who are you looking for?" ”

Chen Yi's eyes fluctuated for a moment, and he smiled: "We're looking for your mother, is she there?" ”

Hearing this, the little boy turned around and ran to the living room and shouted, "Mom, there are a few uncles looking for you outside." ”

"Let them in."

At the position of the sofa in the living room, there was a weak female voice, with a hint of hoarseness.

"Uncle, come in!"

"Thank you."

Chen Yi walked in and closed the door, and at the same time, the woman's voice sounded again: "Tong Tong, you go to the bedroom first and close the door to play for a while, and your mother will give you your mobile phone." ”

The boy was delighted, took the phone very happily, and then bounced out of the living room, and then heard the sound of the bedroom door closing.

Chen Yi walked to the living room and saw a woman in her thirties with a beautiful face, half-lying on the sofa, she seemed to have lost all her strength, and kept rubbing her forehead.

When the woman looked over, Chen Yi could see the redness and swelling of her eyes, and he could also see the despair, sadness, and confusion about the future in her eyes.

"Mrs. Cao, excuse me."

Chen Yi tried to keep his tone as calm as possible.

It was supposed to be a perfect family, but now that her husband is dead, leaving behind a lonely wife and a son who has just become sensible, it will be the darkest moment in her life for Mrs. Cao.

Fortunately, having the care of children can be regarded as a ray of comfort in the darkness and a source of courage to continue to live well.

The boy still doesn't know what happened, and he doesn't know how long he can hide it.

You can tell the other party that your father is on a business trip in a year or two, and it will be difficult to fool in three years, four years, and ten years, and then it will be a second injury to Mrs. Cao.

"The police, yes? Have a seat. ”

Mrs. Cao was still rubbing her forehead, as if she wanted to relieve her grief, but it was obviously impossible for this method to work, she just didn't want to be idle, she didn't want to stop.

Several people sat down.

"Has the murderer been caught?" Mrs. Cao asked.

Hearing this, Zhao Qiming and the others looked at each other, it was only the third day, to be precise, the second day.

Chen Yi spoke: "Not yet, so I hope Mrs. Cao can calm down for a while and answer our questions, maybe your inadvertent words can bring us great help in tracking down the murderer." ”

"Please believe that we want to catch the murderer, and we have the same mood as you."

He didn't say anything about mourning, understanding your feelings, and for a wife who had just learned of her husband's death, this pale comfort sounded no different from standing and talking without a backache.

Hearing this, Mrs. Cao's movement of rubbing her forehead stopped, turned her head to look at Chen Yi, and then sat up a little straighter from the sofa.

"You're the police officer in charge of this case." She asked.

Chen Yi nodded: "Yes." ”

Mrs. Cao was silent for a while, then said, "I'll go and pour you a glass of water." ”

Chen Yi hurriedly spoke: "No need, Mrs. Cao, let's get straight to the point." ”

Mrs. Cao: "Okay, you can ask." ”

Chen Yi: "Before that, can you allow my colleagues to go to Cao Yuning's room and study?" ”

Mrs. Cao raised her hand and pointed: "Yes, over there, let's go." ”

Chen Yi turned his head and looked at Zhuo Yun and Qin Fei, the two nodded in understanding, got up and left the living room.

At this time, there were only three people left in the living room, and Chen Yi asked the first key question: "Does Cao Yuning have any enemies?" ”

To this matter, Mrs. Cao replied very simply: "Absolutely not." ”

Chen Yi: "Is there a problem with the relationship between him and his students?" ”

This question was very direct and sharp, causing Mrs. Cao's brows to furrow, and then she said categorically: "Absolutely not, I promise this, don't waste time in this direction." ”

"Yuning and I met when we were graduate students, and we both had our first love."

"His tutor is very good, and he is a scholar, including me, so he will never do the things you refer to that are immoral."

"And we all communicate with each other on mobile phones, and we have never found suspicious contacts and chat records, and he rarely goes out alone."

Hearing this, Chen Yi was slightly silent and continued to ask: "What about you, Mrs. Cao, do you have any enemies?" ”

Mrs. Cao shook her head again: "No." ”

"I said, don't go in the direction of the enemy, it's impossible for our whole family to make enemies, please believe me."

Chen Yi was noncommittal and said: "Mrs. Cao, the murder has just happened, don't be so sure, any situation is possible, so please Mrs. Cao try to recall, from the day you and Cao Yuning met, whether anything unusual happened." ”

Mrs. Cao glanced at him and said, "No, everything is very calm." ”

Chen Yi: "Isn't there a time when it's not calm?" ”

Mrs. Cao: "No...... Oh, there is. ”

Chen Yi raised his eyebrows: "Huh?" What's up? ”

Mrs. Cao: "His father died eight years ago, which was not a quiet time for Yuning, and then he was in a very bad mood for several months, and it was not until I became pregnant that he gradually returned to normal. ”

Chen Yi: "Died of illness? ”

Mrs. Cao nodded: "Yes, very serious high blood pressure and stomach problems, died in the hospital." ”

"Other than that, there's nothing."

Chen Yi: "Does he have a rival in love?" ”

Mrs. Cao was surprised for a moment and said, "Of course not, I have been single before I met him, although there were people who liked me during the period, but I have not been in touch for a long time." ”

Chen Yi: "In other words, Cao Yuning has no enemies, and there are no competitors with competing relationships. ”

Mrs. Cao: "Yes. ”

When asked this, Chen Yi recalled the process of the case in his mind.

The time of the crime was probably last Friday afternoon, Cao Yuning did not return home after leaving school, and was found dead in the suburbs the next day.

Mrs. Cao called the police that night, combined with the victim's mobile phone, so the police quickly locked down the victim's identity.

It is worth mentioning that Cao Yuning did not drive when he left the school, but walked out of the school gate, and the destination is unknown.

Probably, it was the murderer who called it out.

However, if the murderer in this case is the same person as the murderer more than ten years ago, Chen Yi personally thinks that it is not very likely that Cao Yuning is the murderer and called out of school, because it is easy to leave clues for the police to investigate.

Whether it is mobile phone contact, face-to-face contact or finding someone to convey it on your behalf, you can find out the physical characteristics and even get a clear portrait.

The murderer in this case is a cautious and intelligent person, and he should not mess around in the university where the cameras are all over the place.

The safest way is to squat like a cheetah, waiting for the appearance of the prey, Cao Yuning always has a moment when he goes out alone without driving.

If this is the case, is there any gain from checking the doctors and medical-related personnel who have been absent from work in the city recently?

However, there is no clear evidence to prove that the murderer's profession is a doctor, and it can only be said that the possibility is relatively high.

"Mrs. Cao, are you sure that Cao Yuning did not have any abnormalities before he disappeared last week? Please recall carefully. Chen Yi spoke.

Hearing this, Mrs. Cao considered that she couldn't be sloppy about her husband's death, so she thought about it seriously for a long time, and finally shook her head: "I'm sorry, I really didn't find anything abnormal, it's exactly the same as usual." ”

Chen Yi: "Did he see a doctor because he was not feeling well?" ”

Mrs. Cao: "No. ”

Asked this, Chen Yi turned his head to look at Zhao Qiming, and asked if the other party had anything he wanted to ask, and the other party shook his head slightly.

There are no enemies, no competitors, and no money, and the means of committing crimes are the same as more than ten years ago, and the possibility that the murderer is the same person is increasing.

Afterwards, Chen Yi and Mrs. Cao continued to chat for a while until Zhuo Yun and Qin Fei came out.

Zhuo Yun came to Chen Yi's side and whispered, and then Chen Yi looked at Cao Yuning's wife: "Mrs. Cao, can we take Cao Yuning's computer?" ”

Mrs. Cao did not refuse, nodded and said, "Yes, you can take it, you can take whatever you want, as long as you can catch the murderer of my husband." ”

Chen Yi stood up and said, "Thank you, Mrs. Cao." ”

"I'm sorry for today, if there is a major breakthrough in the case, we will notify you immediately."

"By the way, the news of Cao Yuning's death, please don't spread it for the time being."

The five of them left with Cao Yuning's computer and came downstairs, where Chen Yi looked at Zhuo Yun and the others.

Both of them shook their heads, indicating that there were no suspicious findings in Cao Yuning's bedroom and study.

Zhao Qiming said: "It's very difficult to do, even if there are suspicious things in the study bedroom, we probably don't know in front of us, the murderer's motive is the biggest problem in this case." ”

Shi Xin said at this time: "When I go back in the evening, I will find a way to check the monitoring and see if I can find something." ”

Chen Yi raised his hand: "No, let others check the monitoring, you have other tasks." ”

When Xin was slightly stunned: "Other tasks?" ”

Chen Yi snorted and said: "The emergence of a new case is very important, it must be thoroughly investigated, and everything about Cao Yuning will be investigated clearly, and this matter will be handed over to Deputy He Branch." ”

"He should understand that I need all of Cao Yuning's movements, even the posts and messages that have been posted in the early years but have been deleted, dig them out."

"Is that okay?"

Shi Xin glanced at the computer in Qin Fei's hand, nodded and said: "Yes, this is my strength, as long as it is the traces left by Cao Yuning on the computer, whether it is local or network, whether it is deleted or not, I will check it out and sort it out." ”

"Time is the word...... Two days or so. ”

Chen Yi: "Okay, then it's hard work." ”

"It's too late today, let's go back first, and go to Cao Yuning's school tomorrow to find the school principal to get Cao Yuning's file."

"Also, Captain Kong Hanyong I want to meet him, does Captain Zhao find it convenient?"

Hearing this, Zhao Qiming hesitated: "This ......"

"This case has hit Master very hard, he doesn't know that the murderer may appear again, I'm afraid he ...... I can't stand it. ”

Chen Yi: "I don't think Captain Kong is so fragile, if you want to say who has the greatest determination to solve this case, it should be Captain Kong." ”

"He has been investigating this case for so long, if you can talk to him, it will get twice the result with half the effort."

"What does Captain Zhao think?"

Zhao Qiming was silent for a while, and finally agreed: "Okay, I'll take you to see my master tomorrow morning." ”

……

The next day, Jiangcheng University, Chen Yi and several people came here and met with the president.

When Xin didn't have a match, at this moment he was in the Jiangcheng City Bureau, making every effort to conquer Cao Yuning's computer and mobile phone.

The principal's surname is Chen, and Chen Yi has the same surname.

"Captain Zhao? Long time no see, why are you here? "It seems that President Chen knows Zhao Qiming.

Zhao Qiming smiled and said, "Hello Principal Chen, there is a case, I'm sorry to disturb you." ”

"Let me introduce, this is the leader of the provincial department's task force, Chen Yi."

"Huh?" Principal Chen turned his head to look at Chen Yi, with a look of surprise on his face, so young.

After reacting, he stretched out his hand to Chen Yi and said politely: "Hello Team Leader Chen, we are both destined, both surnamed Chen." ”

Chen Yi smiled politely: "Hello Principal Chen, there is indeed a fate." ”

After letting go of his hand, Principal Chen said, "Captain Zhao said that there was a case just now, I don't know what kind of case it is?" Is our school involved? ”

The news of Cao Yuning's death has not yet been reported, and only his family knows about it.

The degree of secrecy in this case is relatively high, so I should try not to say it.

Zhao Qiming spoke: "President Chen, we came here this time to take away all the files of Professor Cao Yuning of your school. ”

"Cao Yuning?" Principal Chen frowned: "What's wrong with him?" ”

Zhao Qiming: "I'm sorry Principal Chen, there are some things that we can't disclose. ”

Seeing this, Principal Chen didn't ask much, nodded and said, "Okay, I know, I'll notify the archives office to send it over immediately, please wait." ”

Zhao Qiming: "Thank you. ”

After getting Cao Yuning's file, several people left the school and drove on the road, preparing to go to Kong Hanyong's home.

The distance is not far, it will be there in twenty minutes, and it is Qin Fei who is driving.

In the car, Chen Yi opened the file box, began to look through Cao Yuning's information, and handed some of it to Zhao Qiming and Zhuo Yun.

As time passed, Chen Yi's gaze froze and he picked up one of the papers.

"Transfer?"

The archives show that when Cao Yuning was studying for graduate school, he was about to graduate and take the doctoral examination, but he suddenly changed departments and switched from history to psychology.

"What transfer?"

Several people in the car looked over.

Chen Yi stared at the information in his hand for a while, and said: "Cao Yuning once changed departments, and he transferred when he was in graduate school, which is quite rare. ”

Undergraduate department changes are nothing and common, but graduate students are different.

In principle, it is not allowed to change majors during the graduate school period, and it is necessary to negotiate with the graduate supervisor and the other party agrees.

Zhao Qiming: "Why didn't Cao Yuning's wife say this yesterday?" ”

Zhuo Yun spoke: "Maybe I don't think it's abnormal, what can the change of the early years have to do with this murder." ”

"Team Leader Chen, do you think there's a problem?"

When he came to Jiangcheng, there were outsiders there, and Zhuo Yun no longer called Chen Yi's full name, and he usually did it.

Chen Yi said: "I can't talk about the problem, but it is also a new discovery, and it is not reasonable for graduate students to change departments." ”

"And ......"

He looked down and looked at the time of the transfer: "And Cao Yuning's time point of transfer is relatively close to the time of his father's death, is there any blow?" ”

"By the way, what does Cao Yuning's father do."

Zhao Qiming replied: "Like Cao Yuning, he is also a university professor, so he can be regarded as inheriting his father's business." ”

Chen Yi: "What major?" ”

Zhao Qiming: "History...... Well? Is there a connection? ”

Chen Yi put down the document and looked at Zhao Qiming: "Cao Yuning's father studied history, and Cao Yuning himself studied history in his early years, but at the time when Cao Yuning's father died, Cao Yuning suddenly switched to psychology. ”

"Let's not talk about coincidences, there is still a relatively high possibility of a connection here, but it is not necessarily related to his death."

Zhao Qiming thought for a while and said: "The illness and death of my father, who studied history, caused Cao Yuning to lose interest in the history major, and he couldn't get out of the haze of the death of his relatives, so he switched to psychology, both studying and cultivating himself. ”

"Is this explanation reasonable?"

Chen Yi nodded: "It's very reasonable, the possibility is still relatively high, let's put this matter on hold for now." ”

New leads are sometimes useless, unless some information emerges in the course of a future investigation that can be matched with clues that would otherwise be useless.

Now is the early stage of the investigation, what we need to do is to cast a wide net, look for more clues, whether it is useful or not, write it down first, and finally see if it can be connected.

If it can be connected, it means that the case is moving forward.

Several people stopped talking and continued to read the information.

Nothing else, Cao Yuning graduated from graduate school step by step, and then stayed in school, and then was admitted to the doctorate during the school, and his life was still very wonderful and successful.

It's a pity that somehow he was buried in the soil, his head was broken, and he still watched himself die.

Twenty minutes later, Chen Yi and the others came to Kong Hanyong's house.

Kong Hanyong's wife went out to buy vegetables, and he was the only one in the family at the moment.

When the door was opened, the other party was holding a shower full of water in his hand, and he was supposed to go to the balcony to water the flowers.

"Qiming? What are you doing here. ”

Seeing Zhao Qiming, Kong Hanyong was a little surprised.

Nearly sixty years old is not very old, but Kong Hanyong's hair is already gray, and his body is still a little rickety, but I don't know if it's because of the case more than ten years ago.

Mood is very important, if the mood has been depressed, it will be reflected in the complexion in the long run.

Kong Hanyong's complexion is not good.

"Master......"

Zhao Qiming hadn't seen Kong Hanyong for a while, and when he saw the white hair on the other party's head, he was inexplicably sad.
