Infernal Hero Chapter 82: Master of Criminal Investigation

Criminal investigation is not only a technical subject, but also a social subject. When we focus too much on the clues and try to find the truth from these intricate clues, we often overlook the simple part of the case in the first place.

Professor Li Yunqing is a superstar in the field of criminal investigation, just like Cruyff was in football. Before the age of sixty-five, he served as the chief criminologist of the FBI for a long time in the United States, established a criminal forensic science laboratory, and solved many strange cases. After the age of sixty-five, he returned to China, where he devoted himself to writing books and making speeches, and also served as the chief criminal investigation counselor of the ministries and commissions.

Today, the dean of criminal investigation appeared in the case analysis class of the Police Academy and publicly proposed to get to know a child first. After saying a word, there was an uproar in the classroom, and all eyes were focused in one direction.

The child is listening to music, and his eyes are half-closed, indicating that he is very intoxicated at the moment. Didn't even notice the changes in the classroom.

Song Qiang was very embarrassed, while Li Bowen, the grandson of the old gentleman, was surprised. ,

Gu Tianyou suddenly realized, and soon fell into a daze. Why are you looking at me like that? What does Director Song's straight eyes mean? And who is that old gentleman? Not taking a case analysis class? What are they all staring at me for? Huh? Why does this old gentleman look so familiar?

"You are Gu Tianyou?"

"Ah, yes, I'm Gu Tianyou, hello, who are you?"

Song Qiang can't wait to rush up to give Gu Tianyou a mouthful to wake up this **** who doesn't know how to be blessed. If the person the old gentleman paid so much attention to was Song Qiang, it would be hard to say whether he would be happy on the spot. Of course, he could only think about it. First, the old gentleman didn't pay attention to him, and secondly, he wasn't brave enough to slap him.

"I'm Li Yunqing." The old man did not mind introducing himself again.

Gu Tianyou instantly understood why he was in the limelight. This guy in the criminal investigation world must have spoken to him just now. And he was immersed in the Lu Ziqi incident and did not respond at all.

This is a very rude and rude thing to do.

The old gentleman didn't mind, and Gu Tianyou didn't panic.

Gu Tianyou stood up and said frankly: "I'm sorry, my ears were deserting just now."

Li Yunqing pulled up a chair and sat down, casually: "My ears are deserted, what are you thinking about?"

Gu Tianyou said: "I'm thinking about a case."

"You don't have to participate in the next case discussion, and continue to think about your case. If you don't mind, I'd like to hear what case you were thinking about after class." Li Yunqing said with a smile: "Let's continue. Discuss the case."

The old professor cleared his throat and said in a loud voice, "Students, the reason why I allow him not to participate in the discussion of this case analysis is because Gu Tianyou once made a decisive opinion on the direction of detection during the detection of this case. "He turned his head and asked Song Qiang, "Mr. Song, where is the discussion?"

Song Qiang said: "The students are analyzing the case and expressing their opinions."

Li Yunqing nodded and said: "Okay, then I will talk to you about the detection process of this case, as well as a few opinions of mine."

Everyone has already heard about the case, Mr. Song, so I won't repeat it. Let’s talk about the positioning of the detection direction that I just mentioned. Before I start talking, I will tell my classmates a story. After listening to it, you can see what kind of inspiration you can get.

That happened last summer. On the road where the poisoning and murder case occurred, a Volkswagen car had a tire blowout accident, broke through the guardrail, rolled over and fell into the roadside drainage channel. A family of three was seriously injured and trapped in a car unable to save themselves.

The car was squashed during the rollover, and the family of three was trapped in the car. The male driver was stuck between the steering wheel and the seat, and the six-year-old boy was squeezed into the back seat by the badly deformed car. , the leg was stuck under the passenger seat, and the blood vessel was ruptured, but as long as the rescue and fashion were not enough to threaten life. The female victim was trapped in the co-pilot's position from the waist down, suffered a head injury, and lacerated arteries in her arms.

A few minutes later, road protection worker Cao Xuewen passed by the accident scene. After hearing the male driver's cry for help, the man crouched in front of the car and discussed the issue of the rescue reward, and then called for Sun Youcai, a passing scavenger, and the two worked together. Attempts to turn the accident vehicle over were unsuccessful.

About ten minutes later, Gao Zhan, a nearby villager, and Jin Xigui, a migrant worker, arrived successively. Together, the four have a good chance of turning the car over and rescuing the injured. In the face of life, time should have raced, but they had a quarrel over a bottle of Sprite that fell out of the car. During the dispute, Gao Zhan took the Sprite drink. Jin Xigui believed that Cao Xuewen had concealed something about the remuneration and refused to help.

Twenty minutes later, when Expressway 120 arrived, it took another ten minutes to rescue the injured. By this time the boy had stopped breathing due to hemorrhagic shock. The woman was in a vegetative state after being taken to the hospital. The male driver was not seriously injured and was soon discharged from the hospital.

Everyone knows what happened next. Gu Tianyou suggested to the task force to adjust the direction of detection to the highway. The task force collected all the accident report materials that occurred on the expressway within half a year, and found the names of the four victims in the accident narrative records, so they locked the suspect in this case, the brother-in-law of a silver mine technician, Liu Zhichao. The suspect confessed to poisoning and murder, and the case was solved.

The class was silent.

A highway of death, a traffic accident, a bottle of Sprite, and four unrelated people.

These words together form the cause and effect of this serial poisoning and murder case.

The students were impressed not only by Gu Tianyou's key tips in this case, but also by the greed and stupidity of the four people and the madness and cruelty of the murderer.

"When you leave here one day and walk into a crime scene, please remember what I said to you today, criminology can never be generalized by data and experiments, understanding human nature is as important as cognitive technology, and technological traces can be faked Human nature is what you and I have. I have been in this industry for forty-eight years, and now I only believe in one thing. All evil deeds have their roots. crime."

"However, I remember you said in a book that all crimes have traces, and finding traces is the basis for punishing crimes." Gu Tianyou raised his hand and said.

"That is the United States, and all allegations need evidence to support it. It has been three and a half years since I returned to China at the age of 65. The national conditions have changed, and the working style of the judiciary has also changed. I have to keep pace with the times." Professor Li Yunqing The old urchin smiled naughty at Gu Tianyou. After saying this, he turned to Song Qiang and said, "Xiao Song, please lend me your feet for a day. I want to talk to this child."

Song Qiang naturally wouldn't refuse. Before he could express his position, one of the students quit, Li Bowen called out, "Grandpa, didn't you say you're here to visit relatives? Take me with you." Li Yunqing looked He glanced at Song Qiang. The latter nodded immediately and said, "Of course, aren't you here to visit relatives?"

Gulou district branch, meeting room.

Li Yunqing was in front, Gu Tianyou and Li Bowen behind, the two young people were stunned as soon as they entered the door.

Ding Baofeng was here, Bai Fenglin was there, Director Ma Fuchun of the Municipal Bureau was there, and Director Meng Qingchun of the Gulou Branch didn't even have a seat. The seat below Ding Baofeng was vacant, Li Yunqing walked over to sit down and said, "The people have arrived, can we start?" Ding Baofeng said, "It's still up to Lao Dai to host."

Dai Xiaolou kept looking down at the file. Hearing that, he raised his head, glanced at Gu Tianyou and Li Bowen, nodded, and said, "First, please ask Comrade Zhao Wanchen from the Gulou Branch to introduce the case to you."

Zhao Wanchen was dressed in uniform and refreshed. Standing behind Meng Qingchun, he took a step forward, salutes the leaders present, and then said: "Several leaders, teachers, and Team Dai, everyone, let me introduce you to the following. case."

At the beginning of last month, there was a vicious wounding incident on Linhu Street in our district. After receiving the alarm, the police in the jurisdiction quickly attacked and arrested the suspect Zeng Wenqiang who was on the run. During the search for the murder weapon, they found 40 kilograms of methyl Amphetamine. After an overnight surprise interrogation by the criminal police team of the branch, Zeng Wenqiang confessed to his crime of entering the city with the poison of fate. At the same time, it was explained that the transfer object was Yang He, the foreman of the Zizuijinmi leisure area.

Forty kilograms of new drugs, there has never been such a large drug-related crime in the history of this city. Gu Tianyou was secretly stunned, only listening to Zhao Wanchen continue to introduce the case.

Subsequently, the criminal police team carried out the order of Comrade Meng Qingchun, the sub-director, and carried out secret surveillance on Zi Zuijin fans. At the same time, the city bureau and the corps were notified of the case.

On the 28th of last month, Comrade Guo Maoxiang, a first-level police officer of the Criminal Police Department of the Municipal Bureau, replaced Zeng Wenqiang and went to Zizuijin Fan to contact Yang He. After that, Comrade Guo Maoxiang disappeared.

At present, it has been 72 hours since Guo Maoxiang disappeared. Zi Zuijin fans are doing everything as usual. Yang He took a leave of absence on the grounds of going home to pick up clothes the day before yesterday afternoon, and went missing on Xingong Street. According to Lao Fu, the second team of the Interpol team who was in charge of surveillance at the scene, he was walking on the road when he suddenly got into an unlicensed Toyota Highlander off-road vehicle that was slowing down.

Due to the uncertainty of Comrade Guo Maoxiang's life and death, the leaders of the Municipal Bureau decided not to take coercive measures against Zi Zuijin fans for the time being, but to conduct investigations by means of secret investigation. It turns out that there are many problems, but they are not enough for criminal cases. During the secret investigation and visit, the whereabouts of Guo Maoxiang were not found. Considering that the meeting place that Comrade Guo Maoxiang and Yang He agreed to meet was not Zi Zuijin fans, so there is no direct evidence to prove that Zi Zuijin fans are related to Guo Maoxiang's disappearance.

Decoupling means losing control of a suspect, which is considered a relatively low-level mistake in the police world.

Gu Tianyou realized that he was in that tone again, and looked at Li Bowen, and found that the boy's eyes were shining and he was more excited than taking the medicine.

"That's Team Zhao, right? I have a question that I want to ask." Gu Tianyou probably understood the reason why he was recruited when he heard this. This case was handled in such a mess, and there were problems with both the handler and the commander. Considering that he might cooperate with these people in handling the case, it would be better to say some ugly things before.

Zhao Wanchen raised his head and glanced at Gu Tianyou, annoyed: "If you have any questions, please wait until it's your turn. Now your task is to listen."

This turtle grandson treats Lao Tzu as an intern child. Playing an official voice in front of Lao Tzu, the Dai team is still not high enough, which round should you be? Gu Tianyou smiled, shrugged, spread his hands and said, "Actually, I think my task should be to listen to a class in the academy." After speaking, he turned around, slammed the door and left.

In the corridor, before Gu Tianyou took a few steps, he heard Dai Xiaolou's voice calling him to stop behind him. Looking back, even Li Yunqing was chasing him.

Gu Tianyou thought to himself, these two came just right. Pointing to the office next to him, he pushed the door and walked in first. A first-level police superintendent was in the office. Seeing that Gu Tianyou entered the office uninvited, he was about to ask questions. He saw Dai Corps, who was carrying the first-level police inspector's sign, followed him. He waved at him, and the buddy immediately got up. went out.

"Old Dai, I won't go around derailing with you. I probably know what I need to do in this case. Originally, since I choose to do this business, I can't be afraid of taking risks. You know I'm not a coward who is greedy for life and fear of death. , but I can't do this stupid stupid business." As soon as Gu Tianyou entered the door, he sat on the table, dangling his legs, and said: "Listen to this case, cooperate with this level of goods, Three heads are not enough for him to sell."

Dai Xiaolou glanced sideways at Professor Li Yunqing and smiled awkwardly. Li Yunqing waved his hand and said, "It doesn't matter, this kid is right. It's true that Zhao Wanchen is my student, but after all, he is still young and has studied in the United States for a long time, and he lacks sufficient knowledge of all aspects of domestic police work. ."

Gu Tianyou continued rudely: "Old Li is right, I see that buddy is just a man on paper, but it's not all because of him, but also my personal reasons. , the kidnapper gang case just ended a while ago, and I have just rested for three months, and I have to go into battle again, and I can't accept it in my heart."

Dai Xiaolou didn't get angry and said with a stern face: "If you have any conditions, just say it directly, don't be around me."

Gu Tianyou jumped down with a snap and said, "The person who knows me is the Dai team, so I'll just say it straight, it happens that both parties are there."

Li Yunqing was slightly surprised: "What? What else is there with me here?"

Gu Tianyou nodded and said solemnly, "You have to do this." After speaking, he turned to Dai Xiaolou and said, "I ask Mr. Li to lead the formation of a task force to restart the secretary of the Qinzhou Municipal Party Committee 19 years ago. The investigation of the murder of Lu Zonglin and his wife at home.”

Dai Xiaolou's face darkened when he heard this, and he glanced at Li Yunqing, who said, "Young man, is this the case you were thinking about in class?"

Gu Tianyou said: "Li Lao is Li Lao, and this is the case, how about it? Are you willing to take over?"

Dai Xiaolou was afraid that Li Yunqing, a madman who solved the case, would agree, and hurriedly said: "Nineteen years have passed since that case, and Mr. Xu, who was mainly in charge of the case at that time, has sacrificed for more than ten years. It's already beyond recognition, and now you have to restart the investigation of this case, does it make sense?"

Li Yunqing frowned and asked, "Is it the case that Xu Tao handled?"

Dai Xiaolou said: "Yes, at that time, Director Ding and I were both members of the task force. The investigation of that case was carried out for a long time, and the two main suspects were ruled out successively. When the third suspect could not be found. In the case of human beings, the case has to be reported and suspended.”

Gu Tianyou actually knew that what he said was reasonable, and felt that restarting the investigation was of little significance, and considering the suspect's current identity, the restart of the case was destined to encounter great resistance. But having said that, things still have to be done, just to call Lu Ziqi's sister.
