Serious Crime Unit 1

Chapter 1139 Greed (32)
Jiang Yiming called the body collector and asked them to bring Feng Zhiyu's body back to the forensic center.Then he called Zhou Ting, Wu Jiang, and Wen Xiaorou and asked them to bring the investigation box and go to Feng Zhiyu's house to investigate the scene. He and Xiao Ke went directly from the hospital to Feng Zhiyu's house.

Luo Jin returned to the team first and arranged the preliminary work for the autopsy.If it was just to check whether Feng Zhiyu died of poisoning or any toxin, all he had to do was extract his blood for testing.

In order to facilitate the investigation of the site, Jiang Yiming asked Zhenxiang to send her son to a relative's house, and then take her home after they completed the investigation.Zhenxiang said that if the case was not solved, she would never go home. She would go back to live with her parents' family, even if she lived there for a lifetime. She very much hoped that they would solve the case as soon as possible.

Just after Jiang Yiming arranged for Zhenxiang and her son to leave, Wu Jiang and the others arrived.The scene was cordoned off by them, and everyone put on survey equipment and walked into the scene.Wen Xiaorou still went to the community surveillance room to check the distribution of monitors and see if she could find any suspicious people in the recent surveillance videos.Lu Yingying did not come, and she continued to trace the whereabouts of Luo Da and Xu Dongfang in the team.

Zhou Ting took a camera to shoot the scene, while Xiao Ke used a multi-band light source to inspect the traces on the ground. It turned out that there were only three types of shoe prints on the ground, all left by slippers. Through comparison, these three pairs of slippers were respectively They were worn by Feng Zhiyu, Zhenxiang and her son. Other than that, there were no shoe marks, indicating that the ground had been mopped recently.Therefore, the extracted shoe prints have no reference value.

After extracting the shoe prints, Xiao Ke extracted hair, body fluids, and dander from the corner of the living room. However, these biological samples were all old and should have been left a long time ago, and they were most likely from Feng Zhiyu's family. , is also worthless. Of course, it has not been tested yet, so it is not certain that it belongs to the three of them.

Wu Jiang is responsible for extracting fingerprints on Wuliangye wine bottles.Wuliangye's outer packaging and wine bottles are both made of glass. There is only one type of man's fingerprints on the packaging and wine bottles, and these fingerprints are most likely left by Feng Zhiyu.Under normal circumstances, at least two people's fingerprints will be left on the packaging box. One is the fingerprint of the wine store owner; the other is Feng Zhiyu's fingerprint.

Zhenxiang said that Feng Zhiyu bought the wine and put it in the wine cabinet. The wine cabinet was very small and could only hold seven or eight bottles of wine. The wine Feng Zhiyu drank was the last bottle, so the wine cabinet was empty.The door of the wine cabinet is made of glass.Wu Jiang inspected the door of the wine cabinet and found only two types of fingerprints, one was a woman's fingerprint and the other was a man's fingerprint.The man's fingerprints were the same as those on the wine bottle. After comparison, it was proved to be Feng Zhiyu's.

Zhenxiang said that she didn't know when Feng Zhiyu bought the wine because she was not interested in wine at all.So she never touched the bottle of deadly poison.Judging from the current situation, the most suspicious person is the owner of the hotel.

What if Feng Zhiyu bought the wine online?Wu Jiang feels that this possibility is very small. If the wine is bought online, the fingerprints of the online store owner will definitely be left on the packaging of the wine. Because the online store owner does not know Feng Zhiyu, he has no motive to poison Feng Zhiyu, and the online store owner The boss was not sure that Feng Zhiyu would definitely buy wine from him.

Wu Jiang asked Jiang Yiming to send Zhenxiang's mobile phone number to his mobile phone. He wanted to call Zhenxiang and ask her if she knew where Feng Zhiyu bought wine.After Wu Jiang received the mobile phone number from Jiang Yiming, he immediately called Zhenxiang to inquire. She said that most of Feng Zhiyu's wine was bought from the Laifu Liquor Store at the entrance of Wolong Community.Usually, I buy one bottle and drink another, and then buy again after drinking. Sometimes I ask the boss to deliver it to my door.However, it cannot be ruled out that customers or friends send wine to Feng Zhiyu.

After Wu Jiang heard this, he felt even more strange. Since the wine was bought from Lai Fu Liquor Store, why didn't the boss's fingerprints remain on it?The outer packaging of the strong-flavor 52-degree Wuliangye is made of transparent glass, which is a good carrier for fingerprints. Unless the boss deliberately hides his fingerprints, fingerprints will definitely be left behind.

Wu Jiang put the packaging box and wine bottle of Wuliangye into the evidence bag, handed it to Jiang Yiming, and asked him to go to the Laifu Liquor Store at the entrance of the community to inquire. At this time, Wen Xiaorou happened to return to the scene, and Jiang Yiming called her up and went to visit together. Because under normal circumstances, it is legal for two police officers to investigate and collect evidence at the same time. Of course, in emergencies and special circumstances, one person can collect evidence. For example, if a drug dealer wants to pour drugs into the toilet, one person can rush to stop him without calling. Go with colleagues.

Jiang Yiming and Wen Xiaorou walked out of the community, looked around, and saw a liquor store on the upper left side of the door. However, due to the angle, they could not see clearly whether it was Laifu Liquor Shop, so they turned left and walked forward until they reached the liquor store. When I walked to the door, I saw several large gold characters inlaid on the lintel of the door, "Laifu Tobacco and Liquor Store".

When Jiang Yiming walked in, a young woman sitting at the counter playing with her mobile phone immediately stood up and asked: "Boss, what do you need to buy? Just take a look." She had a bright smile, a sweet voice, and good looks. She was about 35 years old.

"We are from the Criminal Police Team of the Municipal Bureau. This is our Team Jiang. We need to know the situation from you." Wen Xiaorou quickly took out her police officer ID and handed it to her. She took the ID and looked at it carefully, nodded, and handed it to her. Return the certificate to Wen Xiaorou.

"Are you the boss here?" Jiang Yiming looked down at her slightly. She was at least 20 centimeters shorter than him.

"He's half the owner, right? Our husband and wife opened this shop together."

"May I ask what your surname is?"

"Minggui, my name is Song Xiaoyan. If you want to know anything, I will tell you the truth." She smiled politely, not unhappy because they were not customers.Most citizens admire the police. After all, the police are responsible for protecting the lives and property of the people.

"How long has your store been open?"

"Almost five years."

"Do you know Feng Zhiyu?"

"I know him. He was an old customer of ours. I heard that he suddenly fell ill and passed away after resuscitation failed? He was a generous and generous person. It's a pity that he died at such a young age. His son was only 7 years old." The smile on her face Disappeared, with a heavy expression on his face.

"I heard that he often buys Wuliangye wine from you?"

"I have bought Wuliangye in my store, but not often. After all, Wuliangye costs more than 1000 yuan a bottle, so not everyone can afford it. He may also buy wine at cheaper places." Hers His tone slowed down a bit, as if he was thinking about what to say to his advantage.

"Then when was the last time he bought alcohol from your store?"

"Let me think about it... it's been a long time, more than ten days, right? Yes, it should be September 9, that day is Bailu. My best friend gave me a pound of Bailu tea. Feng Gong was there at the time, so I Invite him to sit down and drink tea. We have the custom of drinking Bailu tea on Bailu day." Her accent did not sound like an authentic local.

"Do you think you sold this bottle of wine to Feng Zhiyu?" Jiang Yiming took out the evidence bag and handed it to Song Xiaoyan to see. She wanted to open the bag and take out the bottle to see, but Jiang Yiming stopped her, "Wait a minute, if you want to see the bottle , please put on gloves." Jiang Yiming took out a glove from his pocket and handed it to her.

She said while putting on her gloves: "This kind of Wuliangye wine has a production date and number. The number is like a person's ID card. It will not be repeated. It can also find out which agency company this bottle of wine comes from. Of course. Unless it’s fake wine.”

"Oh, please help me check the information on this bottle of wine." Jiang Yiming rarely drinks alcohol. He doesn't understand that Wuliangye is so particular.

Song Xiaoyan looked at it carefully and said: "This bottle of wine was not sold by our hotel. Its production date was August 2005, 8. It has been 1 years now. At that time, I had not married my husband, and I had not Open a tobacco and alcohol store.”

"Do you sell this kind of wine in your store now?"

"No, now a bottle of Wuliangye wine that is more than 15 years old costs at least 4000 yuan. We are a small business and it is impossible to purchase aged wine and then sell it. This is very costly and may not be able to be sold."

"Is this wine a fake wine?" "Based on my cognitive ability, this is not a bottle of fake wine... However, I feel that Feng Gong would not buy such an expensive wine for himself to drink. After all, he is just a white-collar worker. Rather than a gold collar.”

“Can you find out from the wine’s barcode, serial number, and year which agent the wine was sold from?”

"This is very difficult. Even if you know which dealer sold it, it is impossible to find the specific person who bought the wine. After 16 years, which wine seller will remember who the bottle of wine was sold to? Unless the owner has a super memory. Strong. Then again, if his memory is that good, he will never have to sell alcohol. He can be an accountant or a network engineer. Oh, being a spy is also good."

"Thank you for your patient explanation!" Jiang Yiming took the evidence bag back and expressed his sincere thanks to her.

"You're welcome, two police officers, please move slowly, I won't send you away."

After Jiang Yiming returned to the criminal police team, he handed Wuliangye wine to Luo Jin and asked him to take it to the laboratory for testing to see if there were toxins in it.

"I just ask Dong Dawei to do it. It is relatively simple and he is fully qualified for the task." Luo Jin said.

"How is it? Have you tested for toxins in Feng Zhiyu's blood?"

"I have detected a large amount of dimethylmercury in Feng Zhiyu's blood. As long as 0.1 ml of dimethylmercury enters the human body, it is enough to be fatal. Dimethylmercury is a colorless liquid at room temperature and pressure, with a volatile and flammable smell. Sweet. Easily soluble in ethanol and ether. Dimethylmercury can also penetrate latex and dissolve rubber and raw rubber. Karen Wetterhahn, professor of toxicological chemistry at Dartmouth College in the United States, accidentally added Dimethylmercury was spilled on her hands, and the dimethylmercury seeped through the latex gloves she was wearing and came into contact with her skin, resulting in her death.”

"So powerful?" Jiang Yiming was very surprised. "This should be a chemical that is strictly prohibited from sale by the state. How did the murderer get it?"

"There are generally three channels, one is chemical factories; the other is chemical laboratories; the third is homemade. Experts can synthesize it by themselves, but this possibility is relatively small. Oh, there is also a possibility that the murderer bought it on the dark web. "

Jiang Yiming had a headache when he heard the words darknet.The dark web is the deepest layer of the Internet, accounting for 400 to 500 times the surface network. The reason why the dark web cannot be retrieved is because of special encoding. It can only be connected through special software or authorization. superior.All personal IP addresses and data addresses on the dark web are invisible and cannot even be tracked.You can buy drugs, guns, explosives, and poisons here... The dark web has become an illegal place for Internet masters and a global problem.

The next day, Luo Jin came to Jiang Yiming's office, put a laboratory test sheet on Jiang Yiming's desk and said, "Team Jiang, a small amount of dimethylmercury was found in the Wuliangye wine you brought back, and The ratio of wine is 500:1, which means that there is 1 ml of dimethylmercury in a bottle of wine, which is 10 times the fatal amount. Feng Zhiyu drank about 0.4 ml of dimethylmercury. Even a god would not save him. No, let alone Luo Cheng?"

"How many drops of water are there in 1 milliliter?" Jiang Yiming asked.

"About 15 to 20 drops of water. Water droplets are also different in size. The capacity of heavy raindrops is much larger than that of a drop of water. Why do you ask this? You are a leader. You only need to have the ability to manage talents. You don't need to detail everything. Understood." Luo Jin said with a smile.

"Nothing, I just want to learn more popular science knowledge from you. Who said you are an encyclopedia of mathematics, physics and chemistry?"

"Excellent! Excellent! If I can learn one millionth of the Encyclopedia of Mathematics, Physics and Chemistry, I will die with no regrets in this life. I really want to ask God to give me ten thousand years, so that I may learn one hundred thousand." one."

"Then we are born at the wrong time. I heard that humans may develop a medicine for immortality by 2049, but it may take another 20 to 50 years to popularize it. We definitely don't have that longevity."

"Don't listen to the bragging of scientists on the Internet. Human beings can only extend their lifespan, but it is absolutely impossible to live forever. Do you know the law of entropy increase? This is the law of thermodynamics proposed by Clausius. Clausius introduced the concept of entropy to describe this This is an irreversible process, that is, heat flows from high-temperature objects to low-temperature objects. Objects are irreversible. To put it simply: the sun will burn out one day, and the universe will collapse one day. How can a person made of flesh live forever?"

"But I heard that lighthouse jellyfish can achieve immortality."

"The lighthouse jellyfish is not called immortality, but rebirth, because after rebirth, its consciousness is not the same as before. In this case, what's the point? It's better to have more children and let your life be transformed in more ways. Keep it going.”

"But some scientists say that if humans continue, they can reach level 7 civilization. Level 7 civilization is the highest level of civilization. Such a civilization is called a god-level civilization, or even a super god. This level of civilization can not only deal with He can control the universe and even create countless different universes. He has the ability to convert, observe, and control 11 dimensions."

"Captain Jiang, this is just a hypothesis. In fact, human beings are currently in a level 0.75 civilization. Most scientists believe that humans will be destroyed before they evolve to a level 2 civilization, such as nuclear war, meteorites hitting the earth, global climate warming, etc. "

"If this is the case, then what is the meaning of our lives?"

"It makes sense. I use my ability to protect people's lives and property. This is very meaningful. Therefore, I am passionate about my work. Let's get back to the subject. How to investigate this case?" Luo Jin already knew that no one had recovered from the scene. Traces of value, so worried.

"The only way to start is to see who has the motive to kill."

"Since Feng Zhiyu's Wuliangye wine was not bought from Laifu Tobacco and Liquor Store, I think the Wuliangye wine may have been given to Feng Zhiyu by the murderer. Most likely, the murderer changed the wine in the wine cabinet."

"The probability of the former is very small, but the probability of the latter is very high. If we find out who gave the wine to Feng Zhiyu, then the murderer's identity will be exposed immediately. The murderer who can buy dimethyl mercury to poison Feng Zhiyu must have a higher IQ. Every Each case has its own attributes. A murderer with a low IQ will be more direct and will use sharp or blunt objects to kill, while a criminal with a high IQ will use poisoning, remote control, accidents, traffic accidents and other methods to kill."

"I have the same idea as you. It is more likely that the murderer sneaked into Feng Zhiyu's house to exchange wine. If this is the case, then the murderer must have the key to Feng Zhiyu's house. Among them, Zhenxiang is the most suspicious. The tragedy of Pan Jinlian murdering her husband happens every day in modern times. Staged.”

"You are wrong this time. The door of Feng Zhiyu's house is unlocked with fingerprints, no key is needed. However, it is too easy to copy the fingerprints of Feng Zhiyu's family. You can buy copied fingerprints online for a few hundred yuan. Some Workers also ask others to punch in with copied fingerprints when they go to work. I was also first to suspect Zhenxiang."

"Apart from Feng Zhiyu's family of three, who else has fingerprints for the access control?"

"We haven't asked Zhenxiang yet because she looks too sad and not very clear-headed. We will ask her next." Although life is at stake, Jiang Yiming usually waits for the family members of the deceased to calm down before proceeding. Question them.
