When talking about the case, the two stopped laughing and joking. Huang Qifa moved a chair, sat upright, and then began to introduce it.

"The incident started a month ago. A fire broke out at the Chinese University. The fire happened at night and was located in a remote warehouse, so no one discovered it at first.

Fortunately, the rooms around the warehouse had fire protection systems, so the fire did not cause much damage, except that the warehouse was burned down. However, a burnt body was found at the fire scene."

"Burned corpses? Under normal circumstances, most people who die in fires die of suffocation due to thick smoke, rather than being burned to death. If the corpse is charred, there should be a combustion accelerant, right?" He Jiahui asked immediately

key issues.

Huang Qifai nodded and replied: "It's gasoline."

He Jiahui frowned slightly. Gasoline is so common. In addition to regular gas stations, there are also many criminals selling black market gasoline. In terms of combustion accelerants, there is no way to check them.

"What is the specific cause of death of the deceased?" He Jiahui asked again.

There are four main causes of death for those who died in fires. The most common cause is suffocation due to thick smoke, followed by carbon monoxide poisoning.

The third is mechanical damage, which means that the fire causes the structure of the building to change and the building materials to soften and collapse, killing people.

The fourth is the abnormality of organs and circulatory system caused by extensive burns.

Only Huang Qifai answered: "After forensic identification, the real cause of death of the deceased was extensive burns, which caused damage to the body's circulatory system and triggered organ failure."

"In other words, they were burned to death! This is rare." He Jiahui said.

"We also detected heptachlorane in the body of the deceased." Huang Qifa continued.

"Is it an inhalation anesthetic? It must be a murder case. The murderer stunned the deceased, poured gasoline on it, and burned him to death. This method is cruel enough." He Jiahui paused and then asked: "The deceased

Has your identity been confirmed?”

"The body has been burned beyond recognition. We spent a lot of effort investigating the identity of the deceased, and finally confirmed through DNA that the deceased was Chen Zishuo, the student union president of the Chinese University.

During the day on the day of the incident, Chen Zishuo also appeared at the Chinese University, and all activities were normal. However, he was burned to death at night, so it can be confirmed that the murderer committed the crime on the day of the fire." Huang Qifai said.

He Jiahui thought for a moment and said: "This murder method is worthy of discussion. Since the murderer can stun the deceased, why did he pour gasoline on the deceased and then burn him to death?

He can throw people into the sea, or bury them alive, which is much more secretive. Even if it is arson, there is no need to burn people directly. If the house is burned, the people inside will not be able to escape and will die of suffocation.

.

I think there are only two possibilities for the murderer to do this. Either he had a deep grudge against the deceased, or he wanted to hide the identity of the deceased and make the police investigation more difficult. After all, it would be difficult to identify the body if it was burnt.

However, if you want to hide the identity of the deceased, it is much more convenient to just throw it into the sea or bury it alive. Why create such an obvious fire? You can rule out hiding the identity of the deceased.

That leaves only the fact that the murderer had a deep grudge against the deceased. You can investigate from this aspect and check the deceased’s interpersonal relationships, relationship status and debt situation to see who he had a grudge or dispute with."

"We have investigated what you mentioned. The deceased was just a college student and had not yet entered society. His social relations were very simple. He had a stable relationship with his girlfriend, no enemies, and no financial disputes." Huang Qifai said.

.

"Has the profiteer been investigated? After the deceased dies, who will benefit from it? For example, the insurance beneficiary," He Jiahui asked.

"The deceased did not purchase insurance before he was alive, so there is no way that someone killed him to defraud insurance." Huang Qifai paused and continued:

"As an ordinary college student, the only special thing about the deceased is that he was the president of the student union. After his death, the position of the president of the student union becomes vacant, so the vice president of the student union should benefit!

So we also conducted an investigation in this direction. However, just as we were investigating Fang Moxuan, the vice president of the Student Union, he suddenly disappeared.

We all thought that Vice President Fang Moxuan was the murderer. When he found out that the police had found him, he fled in fear of crime. It was not until ten days ago that we discovered Fang Moxuan's body.

At that time, the typhoon had just left, and a group of photography enthusiasts went to Goubu Mountain next to the Chinese University to take pictures of the rainbow, and saw a corpse buried upside down in the soil, with only his feet exposed."

"Being upside down and buried in the soil? This crime is a bit strange." He Jiahui said in confusion.

Huang Qifai continued: "We confirmed the identity of the deceased. It was Fang Moxuan, the vice president of the Chinese University Student Union. When the body was found, he had been dead for three days.

The cause of death was suffocation due to lack of oxygen, and sevoflurane was also detected in his body. It is estimated that the deceased knocked him unconscious and buried him in the soil. Although his feet were still exposed, it was not the same as being buried alive.

There is no difference."

He Jiahui nodded: "It's because sevoflurane was also found in his body, so you concluded that this was a serial murder case."

"We also investigated the deceased's interpersonal and financial status as usual. Like the first deceased, Fang Moxuan's interpersonal relationships were relatively simple. He had no enemies, no debts, and no disputes with other people. He also did not buy accident insurance.

No one will kill him for insurance." Huang Qiqi said.

He Jiahui thought for a few seconds and then said: "The main purpose of killing people by burying them alive is to destroy the body and eliminate traces. However, the murderer buried the deceased upside down in the soil and exposed his feet. It was clear that he wanted to be killed.

Discovered by others.

In this case, it makes sense that the first deceased was scorched by the fire. The murderer killed so blatantly because he had no intention of hiding his murder at all. He deliberately wanted others to know!

So why did he do this, and what was his motive? To show off? To show off his presence? To warn someone? Or to provoke the police?"

Ordinary criminals will try their best to hide after killing someone, but this time the murderer was afraid that others would not know. He Jiahui was sensitive to the fact that this was a difficult guy to deal with, and most likely he had an antisocial personality.

.

He Jiahui asked again: "Are there any useful clues on the forensic side?"

"Absolutely not!" Huang Qifai shook his head helplessly, and then explained; "The first crime scene was the scene of the fire. After the fire, all traces were burned away, and the forensic evidence could not find any useful information at all.

Although the second crime occurred outdoors, the body was only discovered after a typhoon. You also know that the typhoon a few days ago had rained so heavily that traces of the scene had long been washed away by the rain.

"

"That means the forensic department can't help at all." He Jiahui also felt that the case was a bit difficult to handle.

In modern criminal investigations, forensic evidence and forensic medicine play a vital role. Many times, a trivial discovery by forensic evidence or forensic medicine can become the key to solving a case and help the police catch the murderer.

In this case, the scene was completely destroyed, and forensic evidence was unable to obtain useful information. Without the help of forensic evidence, the difficulty of solving the case also increased significantly.

"Just from what you said, this case is indeed a bit troublesome. Let me go and look at the case files, maybe I can find new clues." He Jiahui said.

…

Regional Crime Unit.

Senior Inspector Ma Jun passed by the door of the utility room and found that the door was open and several workers were clearing away the debris inside.

Ma Jun shook his head inexplicably, then walked into his office and asked, "I saw that the utility room of our serious crime team was cleared out. Does anyone know what to do?"

His subordinate, Uncle Hua, immediately replied: "Sir Ma, you don't know yet! The crime squad is setting up a new group, which seems to be called a special support group."

"Special support? If the crime team needs support, they can directly call the Flying Tigers. Why do they need to set up a separate team?" Ma Jun said with a frown.

"I heard that Inspector Huang specifically applied to the superior. If the office is in that utility room, I guess there are only two or three people in this department." Another subordinate, Yang Zai, said.

At this moment, Huang Qifai walked in from outside and said to Ma Jun: "A Jun, come to my office. I have something to tell you."

After arriving at Huang Qifai's office, Huang Qifai motioned Ma Jun to sit down, and then said, "A Jun, is there any progress in the Chinese University case?"

"There are really too few clues in this case. No useful traces were found at the scene. We have also visited the family and friends of the deceased. There is really nothing suspicious."

Ma Jun sighed helplessly, and then said, "Sir Huang, give me a little more time, and our team will definitely be able to find clues!"

"I have seen the hard work your team has put in these days. The brothers have been working overtime for this case, and I know it. But after so many days, there has been no progress in the case, and the superiors are pressing me hard. I also know

We can't just wait and do nothing."

Huang Qifai smiled slightly and continued: "So after discussing with my superiors, I decided to find a helper to help your team solve this case!"

"Could it be the special support team?" Ma Jun asked.

"It seems that you have received the news. It is true that the crime team cannot hide things." Huang Qifai nodded.

Ma Jun frowned and asked: "Sir Huang, you said that the newly established special support team is here to help us solve the case, so the case is still based on our team, and the special support team must obey my command.

Right?"

"Well..." Huang Qifai hesitated for two seconds and then said: "This case will be solved by the newly established special support team."

"In other words, you want me to hand over the case? This is impossible!" Ma Jun suddenly looked anxious and angry, and he said loudly; "Sir Huang, this is the case of our team, I will not hand it over.

!”

"You can't find any clues to solve the case for the time being?" Huang Qifai continued: "Besides, your team is not completely irrelevant to the case. After the special support team determines the direction of solving the case, it may be necessary to investigate or arrest people.

, it’s all up to you!”

Ma Jun hesitated for two seconds before he realized what Sir Huang meant.

"Sir Huang, according to what you said, we not only have to hand over the case, but we also have to listen to other people's orders! It's better to hand over the case directly!"

Ma Jun snorted coldly and continued: "Sir Huang, how many big cases have I solved over the years! How many people in the entire police force have a crime solving rate that can match mine? You actually asked me to obey other people's orders!"

"Ajun, don't get me wrong. This is collaborative case handling, not who directs who. Solving a case is a matter of brainstorming. Everyone exchanges their ideas and maybe there will be a new direction for solving the case. It's all for solving the case. If someone

The idea is indeed helpful in solving the case, so why not listen to it!" Huang Qi said with a smile.

"That's not because someone is commanding me!" Ma Jun snorted coldly, and then said: "Then let me reveal who the new inspector is. Maybe I know him."

"Anyway, the person will be here tomorrow. It doesn't hurt to tell you in advance. The new person assigned to be in charge of the special support team is Sergeant He Jiahui." Huang Qifai said.

"Sergeant? I want to listen to the command of a sergeant? I'm a senior inspector!" Ma Jun's expression suddenly changed.

"I've already said, this is collaborative case handling!" Huang Qifai said with a smile on his face, "Don't underestimate Chief He Jiahui. Although he has only been a police officer for more than a year, he has been

, he has repeatedly solved major cases."

"What? You've only been a rookie police officer for a year, and you want to teach me how to solve crimes? Sir Huang, are you right?" Ma Jun was so angry that he almost flipped the table over.

Huang Qifai quickly advised: "Ah Jun, don't worry, let me introduce you to He Jiahui, and you will know how powerful he is!"
