Serious Crime Unit 1

Chapter 1236
Zhou Ting cooperated with Xiao Ke to take videos and photos, while Wen Xiaorou went to check if there were any monitors nearby. The result made her a little frustrated: There were two monitors within 28 meters of Building 100, but neither of them was running. They may have been broken for a long time. The monitor should be installed by the village committee or the police station in the jurisdiction.

In order to reduce costs, the village committee cannot call someone to repair the monitor in time if the monitor is broken. The police force and financial resources of the police station are also seriously insufficient. The monitors they install cannot fully cover the streets and alleys of Fangcun.

When Jiang Yiming saw Wen Xiaorou coming, he asked her to go to the landlord with him and ask about Zhenxiang's social background. Unless there were special circumstances, it was against the rules to ask citizens alone, and it would take more than two police officers to question relevant personnel.

The two of them went up to the seventh floor and knocked on the landlord's door. Jiang Yiming thought that the landlord was older, but he didn't expect that the person who opened the door was a man of about 25 years old. After he heard that they were from the criminal police team of the city bureau, he hurried forward and talked to him. They shook hands and invited them in politely.

After the two parties sat down, Wen Xiaorou took out the notebook and Jiang Yiming began to ask: "Hello, what is your surname?"

"Captain Jiang, you don't have to be polite. My name is Fang Qing. The property rights of this house belong to me. I went to Australia to work as a power grid maintenance worker when I was 18 years old. After working for 6 years, I saved a little money and took it when I saw the opportunity. It just happened. The original landlord wanted to sell the house, so he bought it and rented it out to collect rent. My childhood dream was to be a painter, and I plan to spend my whole life realizing my dream." He pointed to a row of oil paintings at the foot of the living room wall. Said proudly.

"Wow, you are great. You have lofty ideals at such a young age, and you don't have to draw for life... Do you know how sweet the tenants on the second floor are?" Jiang Yiming truly admires him. People with long-term goals and lofty ideals are very special. It is valuable, and I plan to use a lifetime of hard work to realize my dream, which is even more valuable!

"I know her. She has also been my model. However, she is not the model I want. She has a vulgar temperament. The model I want is an elegant, simple and innocent girl. It is best to have a light temperament. She had a sad temperament, so I stopped looking for her to be a model."

"How long has she lived on the second floor?"

"One and a half years. She used to live in Qianshan Village, and then moved to my house."

"Does she date a lot of men?"

"I don't know about this. I am addicted to my own painting world and rarely observe or inquire about other people's lives."

"Then have you ever seen her with a man?"

"Yes, I saw two men coming out of her house twice. However, she is a single girl. Is it normal for her to have a boyfriend?"

Jiang Yiming took out his mobile phone and pulled out the photo of Yang Mu from the gallery on the mobile phone. Qiu Hui passed it to him. He handed the phone to Fang Qing and asked: "Look, is he among the two men you bumped into?"

He just glanced at the photo and said, "It's not him."

"You only have to look at it for half a second to be sure it's not him?" Jiang Yiming thought he didn't see clearly.

"Captain Jiang, you have forgotten that I am a painter. I am particularly sensitive to human faces. I can remember the details and features of a stranger's face if I take a serious look at him on the street. A year later, if I look at people again, I can still recognize him when I meet him." He said sincerely and firmly.

"You are so awesome. Can you please leave me your mobile phone number? Maybe we will need your help in handling cases in the future." Jiang Yiming suddenly remembered the recently popular criminal investigation TV series "Crime Hunters". The male protagonist is the same as Fang Qing. With his sharp eyes, he can instantly remember the suspect's facial features and draw them.

Jiang Yiming called everyone to a meeting, and everyone discussed it sentence by sentence, but no result was obtained from the discussion. The six types of shoe prints extracted at the scene belonged to two doctors and two male nurses who went to rescue Yang Mu. One shoe print belongs to Yang Mu, and the last shoe print belongs to whom I don’t know.

Zhenxiang didn’t know who the suspicious shoe print belonged to. Because the shoe print was left by the slippers on Zhenxiang’s shoe rack, they thought it belonged to Zhenxiang’s friend. However, Zhenxiang insisted that no other man had been to her home recently. , and she mopped the floors in all rooms on the afternoon of July 7.

Therefore, the unknown shoe print is very suspicious.The most fatal thing is that the scene has a marble floor. If you walk through it wearing slippers, you can't judge the height and weight of the suspect. You can only judge the approximate data, or the shoe prints of a man or a woman.

According to Dr. Wu, who went to the scene to participate in the rescue, he was the last to leave Zhenxiang's house. When he left, he was afraid that Zhenxiang's things would be stolen, so he closed both doors. No one else entered the scene during the rescue.

In the end, Luo Jin thought that he should consult an expert to see if the mold on the wall could cause Yang Mu's death. No one had ever encountered this problem. Jiang Yiming agreed with Luo Jin's idea.

Jiang Yiming and Luo Jin went to the Provincial Institute of Germs and found Professor Long Jian who specializes in studying germs.He is 62 years old this year. After retirement, he was hired back by the institute to continue working.Jiang Yiming had never seen Professor Long before. When he saw him, he found that he was different. He was tall and thin, with a fair and rosy face, bright eyes, a pair of rimless glasses on his tall nose, and he was wearing a Tang suit. Xianfeng Taoist looks ten years younger than his actual age.

He took several students to do experiments in the laboratory. The director called him out and introduced Jiang Yiming and Luo Jin to him.He stepped forward and shook hands with them warmly, and then asked them to go to the office to drink tea. They chatted while drinking tea, polite and affable.

After the two parties sat down, Luo Jin said: "Professor Long, you are an authoritative expert in the study of germs. We encountered difficulties during the case handling and need to ask you for advice."

"You're welcome to ask for advice. Just tell me and I'll try my best to help you." His voice was clear and soft, making people feel comfortable listening to it.

"It's like this. There was a middle-aged man named Yang Mu. He inhaled a large amount of mold in an environment full of mold and died of acute pneumonia. His family members believed that he was murdered. After our investigation, There was mold growing on the four walls at the scene, especially on the wall near the bed. We are not sure whether Yang Mu committed suicide or whether he inhaled the mold while having fun with his girlfriend, leading to his death from pneumonia. So we have to ask Mr. Please ask for advice."

Professor Long thought for a moment and said: "If Yang Mu himself suffers from pneumonia, and then inhales a large amount of mold, it is very likely to cause poisoning, which will lead to acute pneumonia and vomiting blood and death. However, this probability is very low. Because the odor on the wall The trace amount of mold that came out is unlikely to cause Yang Mu's acute pneumonia."

"Do you mean to say that a large amount of mold needs to be inhaled to cause Yang Mu to have an acute pneumonia attack?"

"Yes, under normal circumstances, even if the four walls of the site are covered with mold, it will take a long time to inhale the mold to cause a pneumonia attack. Do you have photos of the walls on site?"

"Yes." Luo Jin took out the tablet from his bag, opened the picture on the desktop, and handed it to him.After reading it, he said: "The amount of mold emitted from these four walls should not be large. It is difficult to cause Yang Mu to have an acute pneumonia attack. We have instruments to measure mold. If we take it to the site and measure it, we will know how much mold is in the air." content.”

"I don't think you need to measure it. You can accurately judge the mold content based on your knowledge and experience. Is it possible that a large amount of mold was artificially created, causing Yang Mu to have an acute pneumonia attack and die if he was not rescued in time?" Luo Shin asked looking at him.

"It is very likely that collecting mold is an easy task. Mycotoxins can be found everywhere in life, such as moldy rice, corn, pickles, etc. You only need to collect enough mycotoxins and then spread the mold on the site, waiting for the disease to spread. Yang Mu, who had pneumonia, inhaled a large amount of mycotoxins, which could lead to an acute pneumonia attack and death if he was not rescued in time."

"When I dissected Yang Mu's body, I found a large amount of mycotoxins in his lungs and respiratory tract. I didn't expect it to be man-made... Yang Mu's girlfriend Zhenxiang did not vomit blood due to inhaling a large amount of mycotoxins. Why? ?”

"It should be that her lungs and respiratory tract are both healthy."

"But she also fainted. She was sent to the hospital for rescue and soon regained consciousness. Why did she faint?"

"Inhaling a large amount of mycotoxins can also make people have difficulty breathing, causing brain hypoxia and fainting. There is also a possibility that she will faint with blood. She saw Yang Mu vomiting a lot of blood, and she was nervous, so it is normal for her to faint."

“Can you lend us your mold detector?”

"Yes, but I think it's better to send an assistant to help you go to the site to measure. He is more professional than you."

"If that's the case, that's great. Thank you, Professor Long!"

Professor Long picked up the landline on the table and made a call. After a while, a young man walked in. Professor Long simply explained a few words to him and motioned Luo Jin to go to the scene with him. So Jiang Yiming and Luo Jin went to the scene. Professor Long said goodbye.

The assistant's name is Zhuo Qi. He is only 28 years old this year and has been following Professor Long for 5 years. He carried a medium-sized box on his back and got into the police car driven by Jiang Yiming. Luo Jin sat in the back seat with him. He asked Luo Jin Asked what happened, Luo Jin told the situation again.

After a while, they arrived at the scene. Desi Qi took out three sets of film coats from the box and put them on himself first, then asked Jiang Yiming and Luo Jin to put them on. He said, "Mold spores will attach to people's bodies, and there is a possibility that Inhaled into the lungs, it multiplies indefinitely in the human body.”

When they heard this, they were slightly surprised. They had not thought of this when they were investigating. Fortunately, they all wore masks and investigation clothes.
