As soon as he arrived at the door just now, Han Cheng smelled the presence of accelerant in the air through his smelling skills.
However, the fire scene was mixed with a strong burning smell. The burning smell masked the smell of the combustion accelerant, so most people could not smell the smell of the combustion accelerant.
"Young man, can you tell where the accelerant is placed?" Li Qi then asked Han Cheng.
Han Cheng nodded, then walked into the back room, and then followed the smell of the accelerant and pointed out the places where the accelerant was placed.
They were the sofa, bookcase, and curtain corner that were burned down to only an iron frame...
There were a dozen places where accelerants were placed.
An ordinary family places combustion accelerants in many places in the home.
It was obvious that this was a premeditated murder!
Li Qi did not dare to take it lightly and asked the Criminal Investigation Team 2 to collect some test materials from the place where the accelerant was pointed out by Han Cheng and take them back for testing.
The results confirmed that combustion accelerants were indeed present everywhere Han Cheng said.
In view of the seriousness of the case, the Jiangnan Branch immediately established a 518 task force to investigate the Century Belvedere fire case.
The leader of the 518 task force is Li Qi. He has rich experience in solving countless cases and is well-deserved to be the leader.
However, Li Qi proposed to the chief that Han Cheng, who had just been promoted to an ordinary police officer, join the task force.
"Mr. Li, are you sure you want this young policeman who has only been in the police force for one year to join? His qualifications are not enough. I'm afraid everyone will not accept him!"
Hao Ren, the director of the Jiangnan Branch, said in confusion.
"Qualification does not mean ability. My qualifications are high enough, but I didn't notice that there was an accelerant at the scene. This kid is extremely talented and is a criminal investigation material!"
The reason why Li Qi strongly recommended Li Qi to join the task force was after careful consideration.
He had learned about Han Cheng in detail and knew that he had just arrested a wanted criminal whose face had been changed beyond recognition. He felt that Han Cheng was not just lucky, but was gifted.
Because once can be said to be luck, and twice it is definitely ability!
Han Cheng can recognize wanted criminals who have undergone plastic surgery at a glance, and he can also judge the composition of accelerants from complex smells. Isn't this a gift?
Seeing Li Qi's persistence, Director Hao said nothing more.
In addition to being the director, he is also the apprentice brought out by Li Qi!
As an apprentice, he had to give some face to his master, Li Qi.
When the anti-pocket-pocketing team that Han Cheng worked for heard that Han Cheng had been "appointed" by Mr. Li as a member of the task force, everyone was envious.
You must know that even formal criminal police officers may not receive such "respect"!
"Han Cheng, congratulations on joining the task force. Mr. Li thinks so highly of you. It seems that it will be a matter of time before you join the criminal police team. When you join the criminal police team, don't forget the people of our anti-pocket team!" Chief Liu Wei smiled and patted Han Cheng on the shoulder.
Han Cheng scratched his head in embarrassment: "Team leader, please don't praise me. I'm just a blind cat meeting a dead mouse. How can I be respected!"
"A blind cat meets a dead rat. I believe it if it happens once, but I don't believe it if it happens twice in a row. You have been in our anti-pocket team for so long. Since I didn't find out that you have so many hidden skills! But... No wonder you, our anti-pocket team basically relies on the brute force of chasing thieves, but solving crimes is different, we use our brains! You are suitable to be a detective! I like you!"
Liu Wei's compliment made Han Cheng feel a little embarrassed!
518 task force meeting room.
"Everyone, please tell me what you think about the Century Belvedere fire case!" Team leader Li Qi sat in the main seat and asked the team members on both sides.
"Mr. Li, I think the murderer placed so many accelerants in the room, obviously because he wanted no one in the room to survive. I think the murderer's motive should be revenge on his enemies!" Sit in the first seat on the left Detective Chi Shen, a top student wearing glasses, said
Many criminal police officers present agreed with Chi Shen's analysis.
"Then who do you think the murderer might be?" Li Qi continued to ask Chi Shen.
"First of all, what can be ruled out is Lin Shengbin, the husband of the deceased woman, because during the incident, he was thousands of miles away in Haishi..."
"Even if he was not in Nanshi during the incident, it cannot be ruled out that he is not the murderer!" Han Cheng interrupted.
He didn't want to interrupt Chi Shen, who was immersed in what he was talking about.
But he felt that there was a loophole in what Chi Shen said, so he had to interrupt and say a few words!
"Oh? Han Cheng, do you have any new opinions?"
"Mr. Li, I personally think it was done by an acquaintance, because at the crime scene, there was no sign of a door or window being pried open, and the second combustion accelerant was placed under the sofa and other hidden places. It was obvious that the murderer had planned this incident. The fire will never be caused by hastily placing accelerants when the fire breaks out! And through surveillance, we have not seen any suspects entering Room 1808 before and after the fire!..."
Li Qi was quite shocked by Han Cheng's analysis. He didn't expect Han Cheng's thinking to be so thorough.
In his previous life, Han Cheng was an online author specializing in crime-solving novels. He had seen thousands if not tens of thousands of real criminal investigation cases, so his ability to analyze cases was no worse than other criminal police officers.
"Han Cheng, do you have someone to suspect?"
"I want to personally interrogate Lin Shengbin, the husband of the deceased woman!" Han Cheng said without answering directly.
"Okay! I'll make arrangements right now!"
Although Li Qi was confused about Han Cheng's intention to interrogate Lin Shengbin, he still fully supported Han Cheng's approach.
After Lin Shengbin was summoned to the Jiangnan Branch, everyone saw that Lin Shengbin's eyes were red and swollen from crying because of the death of his wife and child. He was haggard, his face was horribly pale, and his eyes were hollow.
I feel very sympathetic to his experience.
When Lin Shengbin saw Li Qi and other criminal police officers appearing in front of him, he suddenly knelt in front of Li Qi: "Officer Li, my wife and children died miserably! You must make the decision for those unscrupulous people." The property fire protection is not done well..."
The meaning of Lin Shengbin's words was obvious. He blamed the property management for failing to take fire protection measures.
It seems that he wants to extort money from the property management company!
"Mr. Lin, please calm down. Let's sit down in the interrogation room and talk again!" Li Qi helped Lin Shengbin up.
After arriving at the interrogation room, Li Qi left Han Cheng alone to interrogate Lin Shengbin with him.
"Uh...Mr. Lin, what were you doing in Haishi on the day of the incident?"
Li Qi originally thought that Han Cheng would have many questions to ask Lin Shengbin when he asked for interrogation. Unexpectedly, Han Cheng sat there without speaking for a long time, so he had to ask Lin Shengbin first.
"I went to the sea market to purchase goods. I am in the clothing business..."
........
Then Li Qi asked Lin Shengbin some random questions.
