Criminal Investigation Notes

On the fifth day of finding Chen Yanqiu's body, Zhang Congyun was taken to the interrogation room of Nancheng Municipal Bureau. He is also the first suspect to appear in this case.

Song Wen looks at the old man in front of him through the glass window of the observation room. Under the light of the interrogation room, his face is strained, and the wrinkles and gullies on his face are more obvious, which makes people can't see what he is thinking.

Today, Song Wen asked Fu Linjiang and Lao Jia to ask questions first. Compared with Lu Si language, Fu Linjiang seems more like a policeman recognized by ordinary people. Lao Jia is not so good at talking because of his age. He hopes to give the old man some authority.

The interrogation was not smooth. It has been more than two hours since the beginning of the interrogation. The information provided by the elderly is very limited. Fu Linjiang asked a lot of questions, but he was silent. When asked in a hurry, he said he didn't know.

At half-time, old Jia came out to pour water and said, "Song team, this old man, is playing deaf and dumb because of his age. I don't know what to ask

Lu Si Yu bit his nails and looked at the white record book. From the morning till now, he has not recorded anything valuable.

Zhu Xiao knocked on the door and entered the interrogation room: "Song team, you asked me to check Zhang Congyun's whereabouts during the period of Chen Yanqiu's death. And then I found this. " He handed Song Wen a piece of printed paper, on which was Zhang Congyun's return ticket for the Spring Festival in his hometown.

Song Wen opened it and went back with Zhang Lili and her granddaughter: "have you checked the information?"

Zhu Xiao nodded his head and said: "yes, during that time, he was in his hometown. I called my relatives to verify that Zhang Congyun's hometown is in Lizhou, and it takes more than ten hours for the train to go back and forth. It can be confirmed that during that time, he did not leave."

Chen Yanqiu's body turned into a mummy. The police can only draw an approximate time zone based on the results of Lin xiuran's autopsy and Fu Linjiang's search for the hotel owner, proving that he was killed during this period of time.

Now, Zhang Congyun's travel information covers this period of time. This discovery means that Zhang Congyun has sufficient alibi to prove that he is not the murderer of Chen Yanqiu, or at least not the direct murderer.

Lao Jia also came to see the information: "I didn't think about it clearly. Since he is not the murderer and has a sufficient alibi, why did we try him for so long and he didn't say it himself? Isn't it a waste of each other's time? "

Lu Siyu thought for a moment and looked at Zhang Congyun, who was silent in the interrogation room, and said, "he doesn't need this to defend himself. Maybe he doesn't know the specific time of Chen Yanqiu's death."

Old Jia said, "so, this old man is not a murderer?"

"I checked their information and found that Zhang Congyun once had a son who died young, and Chen Yanqiu also lost his father in his early years. Maybe the two people have developed empathy in the delicate communication process." "We can question the strangeness of this relationship and think his behavior is suspicious, but without direct evidence, we can't say anything from the perspective of law or profession," Lu said, fiddling with his pen

"In other words, if the communication between Zhang Congyun and Chen Yanqiu is not directly related to Chen Yanqiu's death, even if Zhang Congyun has more doubts, we can't detain him for a long time?"

Song Wen nodded, "if Zhang Congyun is not the murderer, detaining a few hours is already the limit." At this point, he frowned slightly and said, "I still have some things to think about. Why did he lie before?"

From his heart, Song Wen didn't want to let Zhang Congyun go easily. He always felt that there were some doubtful points in this person that could not be explained clearly.

As the relevant person of the case, the testimony of witnesses is often mixed with lies, and it is one of their daily work to identify lies.

But people lie for a reason.

Some people, timid, afraid, have been told, or threatened. Things may not involve them, they think that if they don't mention it or say a fluster, they will not have any trouble; some people lie, they are hiding information, protecting family members, protecting relatives, or having other purposes; there is another kind of situation which is most irritating, but it is also very common. Those people just don't tell you because of what. If it seems to bring trouble to other people's work, they can get pleasure. They are simply hostile to the police, with hate, do not want the case to be solved.

What kind of situation does Zhang Congyun belong to? What are his concerns, the reasons for his concealment of the truth?

Song Wen thought for a moment, stood up and stopped the old Jia who wanted to return to the interrogation room. "This time, I'll come and ask myself."

Lao Jia nodded and was very happy. Song Wen took the hot potato, turned out and opened the door of the interrogation room.

Zhang Congyun saw him come in and looked up at him. The interrogation room was quiet for a moment, only the hum of the exhaust fan was heard.

"I know you may not be the killer of Chen Yanqiu, but..." Song Wen put a stack of surveillance photos taken from Ruyi hotel nearby on the table: "there are both human evidence and material evidence. Do you still want to say, don't you know Chen Yanqiu?"

Zhang Congyun sat there quietly, looked down at some photos on the table, and finally said, "the photos before are not very clear. I am old and have a bad memory. I forgot."The light of the interrogation room fell from the top, and his eyelids drooped, casting a shadow on the lower edge of his eyes. He was not as grumpy as he had been at home, but he could still tell from his words that he was unwilling to cooperate.

Song Wen sat next to Fu Linjiang, "we are just investigating the cause of Chen Yanqiu's death. You are the person he once contacted before his death, and the person who knows that he was still alive. If you are not the murderer, I hope you can provide us with relevant clues. So that we can solve this case. " Such an opening is frank enough, Song Wen almost lit all the cards, he paused and asked, "when did you know him?"

This time, Zhang Congyun was silent for a moment and replied, "it was after the accident."

In the observation room, everyone was relieved, and Lu Si Yu finally started recording. As long as Zhang Congyun was willing to cooperate, he could ask for some information.

“…… Did he approach you as Zhang Rui? "

"No Zhang Congyun shook his head and denied this, "I know he has something to do with my wife's car accident. I also know that he is not the one who actually killed my wife. "

"How do you know that?"

"He told me." Zhang Congyun's voice was calm and hoarse, as if without emotion. "After my wife died, one day, I suddenly received a phone call, and the person in the phone said that he could tell me the secret of my wife's car accident. I went and the man appeared Zhang Congyun said here, pointing to the photo on the desktop, "then I met the young man, who told me the whole process of the accident. He was in a group and received this task. He didn't expect that things would develop like this. "

"And then?" Song Wen asked.

"At first I hated him, and I wanted to beat him or kill him. Because of his existence, the real murderer who killed my wife was not punished. I don't know which bastard killed the man. My wife's death should not be his way to earn money. " Zhang Congyun said here, leaning back on the back of his chair, "he said he was willing to compensate me, but I didn't want it. I asked him who the killer was. But like me, he didn't know much about the whole thing. Then he fainted before I hit him. I had no choice but to take him to the clinic nearby. "

"So, that's how you forgive him? "

Zhang Congyun looked down at his hand and said," I know he is very ill. It will be sooner or later that he dies. What can I do? My wife is dead and I've been compensated. I can't get stuck in that car accident forever. I have my own life. "

Fu Linjiang asked: "knowing that someone was guilty of the accident at that time, why didn't you call the police?"

"How do you know I haven't been there?" Zhang Congyun looked at Fu Linjiang and said with a sneer, "I went to the traffic bureau and said there was something wrong with the accident. You know what the people over there asked me." He paused for a moment and continued, "they didn't ask me where I got it from or what evidence I had, but if I didn't get enough compensation."

The result is really chilling.

Song Wen continued to ask: "you took Chen Yanqiu to the clinic to see a doctor. It seems that you went more than once."

"The second time was because he fell ill in a small hotel and felt that he was going to die. He called me and asked me to forgive him before he died, otherwise he would not be at ease. I feel a little sympathy for him. He didn't know anything about the top bag at first, and He's still a kid, younger than my daughter. I can't just let it go. "

"Where did your model of the South Tower come from?"

Zhang Congyun raised his head and looked at Song Wen: "officer, I know what you are thinking. We are not very close. After I bought him medicine, I saw that he finally got better. That day, I told him that my wife did not go to the south tower when he died. I refused to make up for his money, so he wanted to buy one to compensate me." Speaking of this, Zhang Congyun's eyes finally moved, "in fact, until yesterday, you came to me, I knew he was dead. His death has nothing to do with me. "

Song Wen asked, "last time we went to your house, why did you lie to us?"

"Because I don't want to let these things disturb my life any more. And I'm a little scared... "

Song Wen asked, "what are you afraid of?"

"A person you know, who has spoken and had dinner with, suddenly someone tells you that he is dead, and he is not clear, and who killed him. Isn't that frightening? People's instinctive reaction will say that this matter has nothing to do with themselves? " Zhang Congyun raised his head and looked at them, "besides, you policemen. Shouldn't we go first and find out who killed my wife? "

Song Wen looked him in the eye and said, "when the case is in my hands, I will find out. I will find out the death of your wife and Chen Yanqiu

"Oh." The old man looked at them as if he didn't believe Song Wen's words and gave a sneer. Song Wen did not speak, but understood that he was frustrated. The case happened half a year ago. At that time, he might have hoped that the police could give him an answer.

"What you are saying is true?" Fu Linjiang didn't believe him.Zhang Congyun raised his head slightly: "is my answer unsatisfied with you? You can torture me to admit that I was the one who killed him

"What else do you know?" Fu continued to ask.

"I've finished my story. I really don't know anything else." Zhang Congyun closed his eyes and opened them after a moment. "Can you tell me that he How did you die? "

Song Wen hesitated for a moment and told him: "at the end of last year, just before the Spring Festival, he was stabbed in the chest and found in a chemical plant after his death."

Zhang Congyun nodded and asked nothing more.

After six hours of detention, Zhang Congyun signed and was allowed to leave.

Lu Si Yu sent him out. It was summer, and during the day, he was wearing a coat and trousers. Out of the door of the City Council, Zhang Congyun walked all the way to the bus stop opposite him, and then sat down. His back was bent and his body was curled up. The wind blew his hair. Silver was more than black. Only at this time did people really feel that he was just an old man with a dead wife.

Through the traffic, Zhang Congyun looked up at the Lushi language that sent him out. Their eyes met for a second. At that moment, his eyes were full of vicissitudes and fatigue, but after that, there was a kind of stubbornness, sharp as a sword.

Lu Si Yu wanted to see more clearly, but was blocked by several cars. When those cars left, the opposite platform was empty.

At the same time, in Nancheng Municipal Bureau, song Wengang sorted out his things and came out of the observation room in the interrogation room. Zhu Xiao came up and said, "Song team, I saw just now that the transfer list of Xu team seems to have written the name of Lushi language on it..."

Xu Changying couldn't get around in any case. Song Wen got up and said, "you continue to investigate the case. I'll go to the ad hoc group to communicate."
