Gu Zhiguang replied: "Jiajia Village, Mayuan Township, Changhan County, northwest Hubei Province. ”

"How do I get there by train? Which train? ”

Zhu Kang took out the old train timetable and quickly rummaged through it, and raised his head after a few minutes: "Most of the trains in the early eighties were green cars, and if you take the train, you can choose from this, this, and these trains." Get off at Yiling Station first, take a long-distance bus to Changhan County, and walk for about three hours to reach the village. ”

Zhao Xiangwan asked: "The train that Zhai Xinlian took couldn't get to Yiling Station?" ”

Zhu Kang rolled his eyes: "Here!" Zhai Xinlian took the train from Yangcheng to Chang'an, and Yiling was a halfway station. ”

The criminal policemen of the serious crime team immediately realized the problem, and Zhu Feipeng quickly asked: "On the day of January 17, 1981, what was Jia Shendu doing?" Gu Zhiguang just mentioned that Jia Shendu went back to his hometown during the winter vacation and didn't do a project, so what day did he go back to his hometown? Which train to take? Are there any companions? Is there a witness? ”

That's a great question, but where to find the answer so far?

After a while, He Mingyu replied: "The 1981 missing person case should also be in the hands of the Yiyuan Road Police Station. The file management there is a bit chaotic, not as good as the Jinlianhu Police Station, I don't know if I can find it. When we went to investigate yesterday, the old policeman in charge did not mention this case, and it is estimated that the student was abducted on the train and had nothing to do with Jia Shendu, so he was not impressed. ”

Gu Zhiguang raised his hand and said, "There should be a record in our school security office, I can ask." ”

Zhu Feipeng pointed to the phone: "Hurry up and ask." ”

Gu Zhiguang resigned himself to the telephone and began to dial the phone of the school security office. After some communication, Gu Zhiguang hung up the phone: "They said that they would find Director Yu, who has retired, for this matter, and I will ask later." ”

Investigation and evidence collection is troublesome, you have to keep looking for people, keep asking, after so much time, some insiders have retired, resigned, or even died, and it is really difficult to bring up the old things again.

Zhu Feipeng said: "This point must be clarified. If Jia Shendu also departed on January 17, 1981, then he may be on the same train as Zhai Xinlian. As long as he can find out that he had contact with Zhai Xinlian during that time period and conceal it, then he is a suspect. ”

Zhao Xiangwan suddenly thought: "Is it possible that Shi Tong was also on this train, or met these two people at the train station?" ”

The more I thought about it, the more I felt that it was possible: Shi Tong was often on business trips, and he met Jia Shendu and Zhai Xinlian on the train and at the train station, asked a few words casually, and then broke up. Shi Tong didn't take this matter to heart, but Jia Shendu was a thief after killing people, so he rushed back to Star City before the incident, pushed Shi Tong downstairs and left in a hurry, unaware.

In this way, the motive for the murder is found, and the reason for Shi Tong's murder is found.

Everyone was excited, and if that's the case, there's a trace.

Although train tickets are not real-name system, they will always leave traces. Although Jia Shendu's whereabouts are difficult to trace now, they will always be seen. He is a local celebrity, and when he returns to his hometown, he will be seen, whether he brought Zhai Xinlian with him, and what he did at the end of January 1981, some people must remember.

If you search carefully, you'll always find clues!

Gao Guangqiang stood up: "I will immediately report to our Deputy Director Xu and restart the investigation of the case." Let's take the case of Zhai Xinlian's disappearance as a breakthrough and start the investigation. ”

The action of the serious case team has always been fast, and the next step was quickly decided.

Zhu Kang and Ai Hui went to Zhai Xinlian's hometown;

Gao Guangqiang and Huang Yuande went to Jia Shendu's hometown;

Zhu Feipeng and He Mingyu went to the Yiyuan Road Police Station to look for the case file and all the information related to Zhai Xinlian's disappearance and Dai Minli's murder;

Zhao Xiangwan and Gu Zhiguang went to the security office of Xiang Provincial University and Shi Qiyan's home to understand the situation.

Ji Zhao was stationed in a group of serious cases with peace of mind, took the photos provided by everyone, and began to paint portraits of Jia Shendu, Dai Minli, Jiang Yuchun, and Zhai Xinlian.

Everyone is clearly arranged.

On the way to school, Gu Zhiguang asked Zhao Xiangwan curiously: "What's the use of you asking him to draw these?" ”

Zhao Xiangwan smiled silently.

What's the use? The pictures drawn by Ji Zhao are impressive, more shocking than the photos, and will definitely help to find the person.

Gu Zhiguang is very familiar with Xiang Provincial University, and because of the opening of a detective agency, he has a good relationship with the leaders and employees of the security department. With just a phone call, I made it clear that the person responsible for Dai Minli's murder and Zhai Xinlian's disappearance was Yu Heng, who is now retired and lives in Building 6 in District 5 of the school's family area.

Walking in from the gate of Hunan Provincial University, there is a teaching area in front, a family area in the back, and a shop, post office, bank, bookstore and other supporting facilities in the middle.

Last time, he hurriedly came to rescue Shi Qiyan, Zhao Xiangwan didn't have time to seriously appreciate the beauty of Xiang Provincial University, this time there was plenty of time, and there was a chatter Gu Zhiguang walking beside him, so he really appreciated the beauty of this century-old famous school.

North by Guizi Mountain, the road is wide and smooth, the plane trees beside the road are luxuriant, covering the sky and the sun, and the temperature is instantly two degrees lower when you enter the school. The school is low in the south and high in the north, and when you look along the road in the north-south direction, you can see the high Guizi Mountain verdant.

The building is simple and generous, and the gables are covered with vines, forming a natural and beautiful wall painting.

Gu Zhiguang sighed: "Our school's architecture major is well-known throughout the country, and I was very proud when I was admitted that year. It's just that...... Later, I was a little unprofessional, thinking about detectives and opening detective agencies all day long, but my professional level was not very good, and I was ashamed. ”

Zhao Xiangwan glanced at him: "There are many skills, but you don't press down." ”

Gu Zhiguang's family is a construction company, he is studying architecture, and he can go back to take over the family business at any time. As for the detective agency, it is not certain whether it can become his main business, and it makes no sense to be ashamed.

When Gu Zhiguang heard what she said, he immediately laughed: "Eh, Zhao Xiangwan, did you say that you are really good at talking?" Although there are not many words, every sentence can speak to people's hearts. ”

Zhao Xiangwan did not answer this sentence.

Gu Zhiguang didn't care that she didn't talk much, and continued to introduce the important buildings of the school: "Oh, this is the newly built library in 82, with a large area, high space, and rich collections, isn't it very magnificent?" See! That's the old library ...... before"

Zhao Xiangwan's steps were brisk, and he came to Yu Heng's house with Gu Zhiguang's introduction.

Yu Heng has been retired for five years, and it is the time when he is extremely bored, I heard that some children came to ask for advice, and happily prepared fruits and herbal tea, waiting for the arrival of Gu Zhiguang and Zhao Xiangwan.

As soon as the two entered the door, Yu Heng took out the cut watermelon and greeted with a smile: "Come on, come on, don't be in a hurry to talk about the case first, eat the melon first." You said that you kid, you don't study hard in architecture, you have to open a detective agency, just like when I was young, curious! ”

He stuffed a piece of watermelon into Zhao Xiangwan's hand: "Kid, which major are you?" Is it a new assistant recruited by the detective agency? ”

Yu Heng is full of white hair, tall, slightly fat, with a loud voice, full of spirit, and a military style between his behaviors. Zhao Xiangwan looked up at him and replied politely: "Hello, my name is Zhao Xiangwan, and I am a student at the Public Security University. You're a soldier, right? ”

Yu Heng became more and more happy: "The little classmate has a good eye? A bit of the potential to be a public security. I am a demobilized cadre, assigned to the security office of Hunan Provincial University, and I have been working for more than 20 years. Now that I'm retired and have nothing to do, if you need anything, just come to me. ”

After chatting a few words, taking advantage of Yu Heng's time to pour herbal tea in the kitchen, Gu Zhiguang squeezed his eyes at Zhao Xiangwan: "How about coming to the detective agency to be my little assistant?" ”

Zhao Xiangwan said lightly: "Do you pay your salary?" ”

Gu Zhiguang opened his mouth, and wanted to say that he would send it, why didn't he send it, but after thinking about it, the last time Gu Zhixing wanted to ask her to be a consultant and pay her a salary of 300 yuan a month, she was ridiculed by her, saying that someone offered a salary of 600 yuan to dig her, but she didn't go. Oh, please, please, please. So he said, "Well, I'm still a student, and I don't have much money." The detective agency charges very low, after all, the clients are poor students. ”

Zhao Xiangwan heard what he was thinking clearly, nodded and expressed understanding.

After eating the watermelon, Yu Heng poured another cup of cold mint tea for each person, and looked at the sweat on the faces of the two young people, and then said, "What do you want to ask?" Just ask. Don't look at me retired, my memory is still good, and a lot of cases are in my head. ”

Gu Zhiguang was very happy and owed a debt: "Then I asked." Do you recognize Professor Jia Shendu? ”

The smile on Yu Heng's face was retracted: "I recognize it." ”

[That's a hypocrite, a white-eyed wolf, who has done well in learning, but unfortunately doesn't do personnel. 】

Zhao Xiangwan took out the transcript and was about to start recording, when he heard Yu Heng's heartfelt words, he simply opened the skylight and said brightly: "You just have to say, we just want to check Jia Shendu this time." You must have heard about Shi Qiyan's jumping off the building a few days ago, right? A lot of people are scolding him, and we don't like him. ”

Yu Heng has retired, he is not afraid of things at all, listening to Zhao Xiangwan's open voice and directly expressing his attitude, he is very happy in his heart: "Jia Shendu is a student of Zhu Chengling, you know this, right?" As soon as the movement came, he was the first to jump out and write big-character posters, which made Professor Zhu ...... Alas! If it weren't for the desperate protection of many people, I am afraid that Professor Zhu would have died in Huangquan long ago. ”

Gu Zhiguang and Zhao Xiangwan's eyes widened at the same time.

Yu Heng smiled bitterly: "You were all born in your seventies, right?" At that time, I was still young, and I probably didn't know how worthless intellectuals were during the movement. ”

Gu Zhiguang calculated in his mind and raised an objection: "No, Jia Shendu was admitted to the university in 1965, and he was a sophomore at the beginning of the 66 movement. ”

Yu Heng replied: "This is where he is shameless, he finished writing big characters. reported, after taking the lead in finishing Teacher Zhu, he found a relationship to stay in school, and even mixed a graduate diploma under Teacher Zhu's name. Later, the college entrance examination was resumed in 77 and graduate enrollment was resumed in 78, he said everywhere that it was Mr. Zhu Chengling's graduate student, applying for the qualification of a master's supervisor, Mr. Zhu died in 1973, and there was no way to clarify, but Mr. Zhu's graduate students did not have anything to do with Jia Shen. ”

Zhao Xiangwan suddenly said: No wonder Lu Zhiying never mentioned Jia Shendu, it turned out to be because of this.

Shi Tong is a student of Zhu Chengling's relatives, who teaches with heart and has deep feelings, while Jia Shendu's diploma and academic qualifications are all mixed during the movement, and he also took the lead in rectifying Teacher Zhu. Shi Tong hated and hated Jia Shendu, and it was normal not to interact.

What is hateful is that in the eighties and nineties, Jia Shendu, with that little cleverness, diploma mixed in college, and Zhu Chengling's reputation, actually embarked on the road of professor step by step.

Gu Zhiguang gritted his teeth and scolded: "Miscellaneous!" ”

Zhao Xiangwan also scolded: "Shameless! ”

Yu Heng shook his head: "The ten years of the movement have led to a cultural fault, so college students in the sixties are very precious, Jia Shen was lucky enough to catch up with the last batch of university admissions, and I don't know how he used to mix up a graduate diploma, anyway, it was very chaotic at that time." In short, he was a cunning opportunist. ”

After figuring out the true relationship between Shi Tong and Jia Shendu, Gu Zhiguang asked: "Director Yu, do you remember the murder of Dai Minli in 1975?" ”

Yu Heng sighed: "I know about this case, I was just a small section chief at that time. Although he felt that Jiang Yuchun was a little wronged, all the evidence pointed to him at that time, and there was no way. ”

Gu Zhiguang asked, "What happened that day?" All I learned was a rough description, and I didn't know a lot of the details. ”

Yu Heng fell into the memory.

In December 1975, although the enrollment of the college entrance examination was stopped, Hunan Provincial University enrolled some workers, peasants and soldiers college students, with a four-year study period and normal classes.

Jia Shendu was still a lecturer at that time, taking students to do architectural design, and sometimes he had to be busy until evening.

He got married at the end of 1974 and got a license, and in May 1975, he transferred his wife's relationship from the countryside to Hunan Provincial University, and arranged a formal job.

Jia Shendu and Dai Minli have been married for almost a year, but they have never had children, some people say that Dai Minli crossed the river and demolished the bridge, and after arriving in the city, she disliked Jia Shendu's ugliness and refused to sleep with him, but this is all a private discussion, and it is not allowed.

But Dai Minli and Jiang Yuchun have an affair, which is true.

Hearing this, Gu Zhiguang couldn't help but interrupt and asked: "Since it's a private affair, it should be hidden very tightly, why does everyone know about it?" ”

One sentence made Yu Heng laugh: "You kid." They wanted to hide it, but because they both worked in the nursery, the two fell in love for a long time, and they would always be seen. Jiang Yuchun and Dai Minli are both enthusiastic people, you ......"

Yu Heng glanced at the two young men with clear eyes, and stopped talking.

[As soon as the two of them met, they couldn't wait to arouse the thunder and thunder, and rolled together, and when they looked at each other, their eyes were so sticky that they could pull out the silk, and it was strange if nothing happened. Jiang Yuchun is a temporary worker who lives on the first floor of the school's earliest batch of mandarin duck buildings. Dai Minli went to him quietly, and the two of them made a bit of a fuss, and the bachelors living next to him knew about it. 】

Zhao Xiangwan lowered his head and made a note in this book: Jiang Yuchun and Dai Minli have a personal affair, and they don't know how to hide it.

After writing it down, Zhao Xiangwan looked up at Yu Heng: "In this way, Jia Shendu should know, right?" ”

Yu Heng met Zhao Xiangwan's gaze and found that her demeanor was calm and calm, as if she was young and unaware, and as if she was used to seeing Fengyue, and couldn't help but change her opinion a little: this girl seemed more stable than Gu Zhiguang.

Yu Heng said: "Maybe you know, maybe you don't know, who knows?" Anyway, when the police asked Jia Shendu, he cried and said that he didn't know. He said that he and Dai Minli have a good relationship, a talented man and a woman, and a fellow countryman, the two parents are close, and they have discussed that the two will go back to their hometown together after the winter vacation, who knew that such a thing would happen? ”

Gu Zhiguang sighed twice: "Crocodile tears!" People like Jia Shendu, can cry? It must have been a show for the police. The more he does this, the more it shows that he did it. ”

Yu Heng was shocked and looked at Gu Zhiguang: "Do you suspect that Jia Shen killed his wife alone?" That's a big deal. Jiang Yuchun has been shot, and he doesn't have any family, so you want to overturn the case for him now? ”

Gu Zhiguang glanced at Zhao Xiangwan.

Zhao Xiangwan explained: "At present, it is only an investigation, and there is no conclusion. Just tell us what you know, tell the truth, right? ”

Yu Heng said: "I cooperated with the police investigation at the police station at that time, and I also suspected Jia Shendu. However, he did have alibi evidence at the time, and Dai Minli was killed on the way home from a private meeting with Jiang Yuchun, and there was still a corner of Jiang Yuchun's clothes at the scene, and the evidence was conclusive. ”

Listening to Yu Heng talk carefully, even Gu Zhiguang felt tricky.

On the evening of December 19, 1975, after Jia Shendu had dinner with Dai Minli at home, at about half past six, Jia Shendu said that he would go to the drawing classroom to guide the students to complete the architectural design, and then leave home to go to the old building of the Department of Architecture. At that time, they lived in a single-sided single-sided building with a single bedroom with a kitchen and a toilet, which was considered good for young workers who had just gotten married.

When Jia Shendu returned home at nine o'clock, he found that Dai Minli was not at home. It was winter, it was windy, it was cold, where had she been so late? Jia Shendu knocked on the doors of several houses next door and asked where Dai Minli went, one of them said that he saw Dai Minli dressed up and went out, almost Jia Shendu went out with her front foot, and she went out with her back foot, that tone made Jia Shendu very unhappy, and argued a few words, and went back to the house angrily.

At ten o'clock, Jia Shendu couldn't sit still, and went to look for people with his neighbors next door, and several families walked along the road in the first district, until they found the non-staple food store, where they didn't see anyone. It was cold, and everyone speculated that they were afraid that they would go to a lover, but because Jia Shendu's face was not good-looking, he didn't say it.

At twelve o'clock, Dai Minli still didn't come back, so she called the people from the security department to look for someone together. Yu Heng was on night duty at the security office, and Jia Shendu and a group rushed to Jiang Yuchun's dormitory, but they only saw him sleeping alone, but there was a happy atmosphere in the air in the dormitory, the bed was messy, and there was a red scarf on it.

As soon as Jia Shen saw the red scarf, he rushed over, smashed his fist on Jiang Yuchun's face, and said hoarsely: "This is Minli's thing, where did you hide people?" ”

Jiang Yuchun looked flustered, and a group of people asked him: "What about people?" "His head was a little drowsy, and he was stumbling for a long time.

In the end, he was asked in a hurry, and Jiang Yuchun had to admit that Dai Minli had indeed had a good time with him just now, but he had already left. Because she said that Jia Shendu went home at about half past nine in the evening, and she had to leave before this time.

There was an uproar.

All of a sudden, everyone was accusing Jiang Yuchun of being a hooligan, and yelling to send him to the Public Security Bureau.
