Criminal Investigation Chronicle

On January 2017, 1, it was the Lunar New Year. Zhao Lei was on duty today. Although he was the vice captain, his subordinates had to rest and celebrate the New Year.I thought I would be able to have a stable New Year, but things backfired. It was just past eight o'clock in the morning. Zhao Lei was watching the rebroadcast of the Spring Festival Gala, and the police station received a report...

Zhao Lei quickly led the police to the scene of the crime. The crime happened in a luxurious villa in a well-known rich area in Yanjing.Zhao Lei looked at the deceased and was startled. The way of death made Zhao Lei feel his stomach tumbling, and Xiao Liu, who was traveling with him, had already vomited.The deceased was sitting in front of the washbasin on the first floor of the villa, with a fruit knife stuck in his back. His head was stuck in the washbasin. Severely corroded.The scene was turned into a mess, and the deceased's wallet was scattered on the ground, which was empty, and several other drawers were opened.

The reporter was the secretary of the deceased named Yue Feng, a man in his 30s wearing gold-rimmed glasses. According to Yue Feng, the deceased was named Wu Zhenxiong, a 67-year-old Hong Kong native, a famous philanthropist, and a lot of money. , There are two companies in Yanjing, and this villa was also purchased by Wu Zhenxiong in Yanjing. Wu travels to Yanjing several times a year, this time on January 2017, 1, to handle some company affairs.And Yue Feng would come to look for Wu Zhenxiong at 23:08 every morning. Today, after knocking on the door, the deceased did not answer, and no one answered the phone. Yue Feng opened the door with the spare key, found the deceased, and called the police.

According to the forensic examination, the time of death of the deceased was from 1:27 to 8:9 p.m. on January [-]. The cause of death was that a dagger was inserted into the back, which cut the artery and caused massive bleeding. At the same time, the deceased inhaled a large amount of strong acid in the nasal cavity, indicating that the deceased was pushed into the washbasin before he was alive. Soaked in strong acid, it is conceivable that the deceased suffered great pain before death.Fingerprints of the deceased and another were found on the dagger. "Does Wu Zhenxiong usually carry a lot of cash in his wallet?" Zhao Lei asked Yue Feng. "A lot, basically more than [-] in cash." Zhao Lei picked up Wu Zhenxiong's cell phone and looked through it, pointing to the outgoing call under Yue Feng's missed call, asked someone to record it, and immediately notified the technician to check the number.

After dealing with the scene, Zhao Lei came to the security room of the community and retrieved the monitoring of the night when the crime occurred.It can be seen through monitoring that Wu Zhenxiong returned to the villa alone at 27:6 p.m. on the 8th. At the door, the courier opened the door and left at 8:[-] in the evening. When he left, he accidentally glanced at the camera not far in front of Wu Zhenxiong's villa.No one has been in or out of the villa since then.

And when the courier looked up at the camera, Zhao Lei was surprised and clenched his fists. He watched the surveillance video repeatedly, zoomed in, paused, and compared. Zhao Lei already knew the identity of the courier—it was his incompetent His nephew, Jiang Cheng.The technicians also reported that the number on Wu Zhenxiong's cell phone was the restaurant where Jiang Cheng worked.

Jiang Cheng is Zhao Lei's nephew and the only son of Zhao Lei's sister's family. He is 20 years old this year. He was spoiled and spoiled since he was a child. Dishonest, causing trouble every now and then, either fighting with customers or the boss, changing a few jobs, and now this restaurant delivers food, less than a month in the job, and asked Zhao Lei for money a few days ago, saying that he wanted to change his phone, Zhao Lei also ignored him.

Zhao Lei took out his mobile phone and called Jiang Cheng, and he got through quickly, "Happy New Year, old man, are you ready for the red envelope?" Jiang Cheng was laughing on the other end of the phone.

Zhao Lei asked: "Xiaocheng, where are you, I have something to do with you."

"Oh, I'm in XX Square, I'm looking at my phone here, come over, uncle, and help me choose."

After writing down the location, Zhao Lei immediately led people to rush there.When he arrived, Jiang Cheng was picking out a mobile phone in a mobile phone store of a certain brand. Zhao Lei asked the other criminal policemen to wait in the car, walked over by himself, and said to Jiang Cheng, "Xiao Cheng, this mobile phone is too expensive." "It's okay, old man. We are not short of money." As he spoke, Jiang Cheng took out a stack of banknotes from his pocket, about ten thousand or more, waved them in front of Zhao Lei's eyes, and said excitedly, "Old uncle, rich people's money is really easy to make. " Zhao Lei shook his head with a sigh, and said, "Xiao Cheng, follow me back to the police station to assist in the investigation. You are now suspected of a murder case." After saying that, he immediately restrained Jiang Cheng and dragged him out of the shop. His face was shocked, and he thought the old uncle was joking, but when he saw a few criminal policemen getting on and off the police car, Jiang Cheng realized that Zhao Lei was not joking, nor did he resist. He just said, "Old uncle, I was wronged..." He took Jiang Cheng into the police car and pulled him back to the police station.

Back at the police station, Zhao Lei wanted to ask Jiang Cheng alone first, but immediately received a notice from his superiors that the case involved Zhao Lei's relatives. In order to avoid suspicion, Zhao Lei was not allowed to intervene in the case, and the identity of the deceased was special, so the case was handed over to Captain Li Liang. .Li Liang will retire in two years. He is Zhao Lei's old leader. He has always done things fairly, with clear rewards and punishments.Zhao Lei returned to his office and called his sister to inform him of the incident.

Half an hour later, Zhao Lei's sister Zhao Jun and brother-in-law Jiang Yunsheng rushed to the police station.Zhao Jun cried at that time, "Brother, you know Xiao Cheng, although he is mischievous and disobedient, he is not a bad boy, he will never do that kind of thing." Zhao Lei nodded, comforting Zhao Jun, "Sister, don't worry, if Xiao Cheng is innocent, we will never wrong him. But the current evidence is not good for Xiao Cheng. Sister and brother-in-law, think about it, is there anything unusual about Xiao Cheng recently? Last night he returned After returning home, what special performance did you have?"

Zhao Jun and Jiang Yunsheng thought about it for a long time, and after looking at each other, Jiang Yunsheng said: "Xiaocheng has nothing special to go home recently, but he was very happy when he went back last night. I asked him what he was happy about, and he didn't say anything else. It’s nothing special.” Zhao Lei said a few words of comfort, told Zhao Jun and Jiang Yunsheng to go back, and told him to tell himself immediately if he remembered anything, and to fully cooperate with the police.

Unable to contact the case, Zhao Lei was anxious, so he went to the restaurant where Jiang Cheng worked alone, found Jiang Cheng's colleagues, and asked about Jiang Cheng's recent performance.Jiang Cheng's colleagues and boss all said that they did not find any special behavior of Jiang Cheng.Back at the police station, Zhao Lei looked at his nephew Jiang Cheng outside the interrogation room. Jiang Cheng was very panicked at this time, but it didn't look like the panic after a bad deed was revealed, it was more like an expression of being at a loss, just like People who can't swim fall into the water...

Zhao Lei fell into deep thought. At present, all the evidence shows that it is his nephew Jiang Cheng. When delivering food to Wu Zhenxiong, he saw that Wu Zhenxiong was rich, so he murdered him for money. But after thinking about it, he couldn't explain it. If Jiang Cheng To kill someone, just stab him to death with a knife, why bother to soak Wu Zhenxiong in strong acid?This kind of method is too cruel, and it would not be used if there is a deep hatred. Jiang Cheng ran to buy a mobile phone the next day after the incident, just like a normal person, which is also very unreasonable. After all, leaving behind at the crime scene is obviously not good for Jiang Cheng Jiang Cheng grew up listening to the stories he told him about solving crimes over the years, and Jiang Cheng is very smart, and he is good at logical reasoning, reconnaissance and counter-reconnaissance. Time can't catch Jiang Cheng, Zhao Lei has this confidence in his nephew.

The criminal police who went to investigate returned to the police station and said that nothing was found in Jiang Cheng's home and the restaurant where he worked. The criminal police who participated in the interrogation also pushed open the door of the interrogation room and reported the interrogation records to Li Liang.Li Liang picked up the interrogation record and read it. Ten minutes later, he called Zhao Lei to his office. "Zhao Lei, take a look at the interrogation report. Although the superior will not let you intervene in this case, I know you well and know that you will not favoritism. There are still some doubts about this case, but the existing evidence is too unfavorable to Jiang Cheng. You first Understand the situation, I have also greeted my subordinates, if you want to interrogate Jiang Cheng, ask them to turn off the monitoring equipment, as long as you do not participate in the case on the surface, you can secretly check the relevant investigation results and inspection reports .” Li Liang said. "Thank you, captain." Zhao Lei said happily, then picked up the interrogation record and read it.

According to the interrogation record, Wu Zhenxiong called the restaurant where Jiang Cheng worked at around 7:8 p.m. to order takeout. Jiang Cheng delivered the food to Wu Zhenxiong's home at [-]:[-] p.m. Then Wu Zhenxiong opened the takeaway and started eating, and kept chatting with Jiang Cheng. When he was almost finished eating, Wu Zhenxiong asked Jiang Cheng to help him peel an apple with the fruit knife on the table. After that, Wu Zhenxiong took out a stack of RMB from his wallet and handed it to Jiang Cheng. Said that he hadn’t chatted with anyone for a long time, thanked Jiang Cheng, and asked Jiang Cheng to accept it, but after Jiang Cheng heard it, he didn’t think much about it, he just wanted to change to a better mobile phone, thanked him quickly and accepted the wad of money, and then Wu Zhenxiong said, Jiang Cheng still had work to do, so he asked Jiang Cheng to leave. Jiang Cheng left Wu Zhenxiong's house with a wad of money, returned to the restaurant, and returned home not long after. This morning, he took the money Wu Zhenxiong gave to buy a mobile phone, and then The police took Jiang Cheng back to the police station. As for what happened to Wu Zhenxiong, Jiang Cheng said he didn't know at all.After reading the interrogation records, Zhao Lei left Li Liang's office, greeted other colleagues, turned off the monitoring equipment in the interrogation room, and entered the interrogation room.

Zhao Lei came across to Jiang Cheng and said, "Xiao Cheng, I'm here to ask you, don't worry, if you are innocent, I will definitely give you justice and bring the real culprit to justice, don't be afraid, I will ask you to answer, If you think of something, add it immediately, and trust the old man." After reassuring Jiang Cheng, Jiang Cheng's mood was obviously much more stable.

"Do you know Wu Zhenxiong?"

"I don't know him very well. I just know that he is a philanthropist in Hong Kong and he is very rich."

"Why does Wu Zhenxiong order takeaway from your restaurant?" "I don't know, anyway, he will order some takeaway these few nights."

"Is it all these days? When did you order the food? When did you deliver the food? Have you been delivering the food? How many days have you been delivering it?"

"I can't remember how many days, it should be four or five days, usually around [-] o'clock in the evening, I was the one who delivered, and I delivered the takeaway, but in their high-end neighborhood, few people are in our restaurant Make an order."

"You deliver food to Wu Zhenxiong, have you ever gone into his house before?" "No, it was the first time last night. I always delivered food to him when he opened the door."

"Then when Wu Zhenxiong let you in last night, did you notice anything special?"

"No, at that time I thought the customer would send it in. Wu Zhenxiong was the only one inside. I put the takeaway on the table and was about to leave, but Wu Zhenxiong started chatting with me and talked a lot. I was too embarrassed to refuse that. An old man."

"What kind of old man?"

"How should I put it, I think that although Wu Zhenxiong is not young, he is tall and energetic, but he looks a little lonely. I think that rich people may have such thoughts, and I also If you don’t understand, just sit there and listen to him.”

"How long did he talk, and what did he say?"

"He said everything. At first he asked me about my basic situation, how old I was, what education I had, how long I had been delivering food, and then he said about himself, saying that he had no children. Now that he was old, he didn't even have anyone to talk to. He also said that he had "didn't meet an opponent in half his life", and I thought to myself, this person is quite pitiful. Although he has so much money and looks awesome, in the end, he still has to find me a food delivery guy to confide in, Or just because I am a food delivery man, I am different from his enemies in the business field and people around him who covet his wealth, so I will complain to me. After talking like this for more than 20 minutes, he eats It's over, let me help him peel an apple, I picked up the apple and fruit knife from the fruit plate on the table, and helped him peel an apple, then he stood up, approached me, took out a wad of money from his wallet, and handed him an apple. Give it to me, and said, thank me for chatting with him, and let me take the money. At that time, my brain became hot, and I thought that rich people can make so much money by chatting and peeling an apple. I declined a few times and saw that he was determined, so I accepted the money, isn’t it just a good time to buy a mobile phone.”

"And you left?"

"Yes, after he gave me the money, he looked at his watch and said that I had to go back to work, so he let me go without delaying me."

"You said he looked at his watch?"

"Yes, it's the mobile phone. He checked the time on the mobile phone."

"Xiao Cheng, did you eat the apple you peeled for him?"

"No, I put it in the fruit bowl for him."

"Is there anyone else in Wu Zhenxiong's room at that time?"

"Probably not, the house is quite big, I just listened to him at the dining table, and didn't go to other rooms to see it."

"What time did you leave?"

"At 08:30 in the evening, I checked the time when I went out."

Zhao Lei and Jiang Cheng asked and answered, and Zhao Lei wrote on a piece of paper: regular and fixed time "floating and sinking for half a lifetime without encountering opponents" fruit knife.

"Old man, it is said that 'a man who is about to die speaks kindly', do you think Wu Zhenxiong knew that something would happen to him last night, so he talked with me for so long?" Jiang Cheng said casually.

Zhao Lei stopped the pen in his hand, pressed his temple, and added on the paper: Prediction.Said to Jiang Cheng: "Xiao Cheng, I'll investigate the case right away, and you can carefully recall the situation at that time, and tell me what comes to mind." After finishing speaking, Zhao Lei left the interrogation room.

The forensic autopsy report also came out. The time of death of the deceased was between 27:8 and 15:8 on the evening of the 45th. Strong acid had been inhaled before, but the acid was limited to the upper respiratory tract and esophagus, indicating that the deceased died after inhaling strong acid for a short time. It is speculated that the deceased was either pressed in the strong acid of the sink, and then the murderer stabbed the deceased with a fruit knife in the back, and then pressed The dead is kept from struggling, and the murderer leaves after death, or the murderer first stabs the dead with a fruit knife in the back, and then presses the dead into the strong acid of the washbasin. In short, the time interval between the stabbing and the immersion in the strong acid is very short. It did not exceed 1 minute. In addition, a large amount of undigested food was found in the stomach of the deceased. After comparison, it was consistent with the takeaway delivered by Jiang Cheng. However, Jiang Cheng's fingerprints were only extracted from the fruit knife, and Jiang Cheng's fingerprints were not extracted from the deceased. It may have been cleaned up, or it may be that after Jiang Cheng stabbed the fruit knife, he put on gloves and pressed the dead into the strong acid pool.

After reading the autopsy report, Zhao Lei asked, "Has the identity of the deceased been confirmed?"

"Confirmed, through comparison of fingerprints, the deceased is Wu Zhenxiong."

"What is the height and weight of the deceased?"

"Height 1.8 meters, weight 76 kilograms."

"Have any apple residues been found in the deceased's stomach?"

"No."

Zhao Lei didn't say anything more, thought for a while, checked the photos of the scene, and added a few words on the paper: The body shape is stronger than the distance between the two injuries of Apple.After writing this, Zhao Lei rushed to the police academy.
