Serious Crime Unit 1

Chapter 1226 The Poison of Love (3)
"Luo Jin, why did the murderer buy a 0.08 mm needle to poison Li Dacheng?" Lu Yingying asked.

"Because there is almost no pain when such a thin needle pierces a person's muscle, and the deceased took an overdose of sleeping pills and would not wake up from the pain, so such a thin needle must be used."

"Has it been analyzed how many milliliters of Taipan snake venom was injected into the deceased?"

"It's very small, probably between 0.02 and 0.01 milliliters, but it's enough to be fatal."

"If Li Dacheng committed suicide, who is the most suspect?" Jiang Yiming asked everyone.

"I extracted Li Dacheng's fingerprint from the fingerprint sensing area on the electronic door lock. He should be the last one to unlock the door..." Xiao Ke said.

"Li Dacheng doesn't have to be the last one to enter, but he needs to know the time and number of times the door opens and closes in the early morning that day. I will complete this task." Wen Xiaorou objected to Xiaoke's statement.

"The scene was a secret room. I think the biggest suspect is Liang Nuanyu. The couple slept in separate rooms. It may not be because Li Dacheng was a light sleeper, but because the two were not emotionally harmonious. We need to conduct an in-depth investigation into Liang Nuanyu's social relationship." Wu Jiang said.

"Since everyone thinks this is a well-planned murder, we will officially open the case for investigation today. Lao Wu and Xiao Ke went to investigate Li Dacheng's social background, and Xiao Ke and I went to investigate Liang Nuanyu's social background, Yingying Lead the visual investigation team to check the surveillance video of Building 28, and Xiaorou will check the door lock record of Li Dacheng's house." After Jiang Yiming finished speaking, he stood up and walked out. He always does things vigorously and never delays.

Jiang Yiming called Liang Nuanyu and asked where she was?She said it was at her mother's house.Her mother lives in Building 11, Area A, Gold Coast Villa. She was worried that they would not be able to find her, so she sent the location to Jiang Yiming’s mobile phone. After Jiang Yiming saw the location, he thought: Liang Nuanyu is very careful and clear-headed, unlike She is a woman whose husband has just died, which also shows that her feelings for Li Dacheng are not harmonious.

Zhou Ting found out from the intranet that Liang Nuanyu’s mother’s name is Yao Chen. She is 58 years old and is the chairman of the Huaxing Foundation, but is already in a semi-retired state. Her father was once the director of the Municipal Industry and Commerce Bureau, named Liang Shanhan. Later, he made a serious mistake and was sentenced to five years in prison. After two years in prison, he died of depression.

One of her brothers opens a restaurant in Indonesia and earns a lot of money. He has not returned to China for three years because he is too busy. Of course, the main reason is the epidemic.Therefore, it is normal for Liang Nuanyu to wear a gold Rolex watch, and her workplace did not gossip about her. After all, the city government office is Qingshui Yamen.

Jiang Yiming and Zhou Ting are very familiar with the Gold Coast villa area. They often come here to visit and investigate. They know the location and structure of all villas.Of course, Liang Nuanyu didn't know this.

When they arrived at the 11th villa, Zhou Ting rang the doorbell. After a while, an aunt in her sixties opened the door. She immediately stepped forward to shake hands with Zhou Ting, and then shook hands with Jiang Yiming: "You are from the Criminal Police Team of the Municipal Bureau. Police officer, right?"

"Yes, my name is Zhou Ting, and this is our Captain Jiang." Zhou Ting took out his police officer ID card and showed it to her.This is a necessary procedure during the interview. Otherwise, the person being questioned or interviewed has the right to refuse to answer any questions.

"Please come in, my daughter is waiting for you on the second floor." She made an elegant gesture to invite you. Although she was already an old lady, her movements were neat and agile, her figure was slim and slender, and her hair was dyed burgundy. Wearing a dark red dress, she looks like a girl from behind.

They walked along the stairs to the second floor. Liang Nuanyu came forward, invited them to sit on the large leather sofa, and then started to make tea. Although her expression was gloomy, she was sad but not sad, sad but not painful, and was dressed in a uniform. Wearing a white sportswear, like a pure white lily.

"Ms. Liang, after our autopsy and analysis, we believe that Li Dacheng was murdered." Jiang Yiming said straight to the point.

When Liang Nuanyu heard this, the hand that poured the tea trembled slightly, and the tea overflowed from the small tea cup. She opened her big eyes and asked in surprise: "How is this possible?" She did not believe this result at all.

"This is an undeniable fact. Please believe that we handle cases very rigorously and never jump to conclusions easily." Jiang Yiming looked at her and said that although she was 36 years old, she looked only about 28 years old. Women favored by God, of course, may be because their genes are too strong.

"Then...how did my husband die?" she asked with confusion and regret.

"He was killed by being injected with Taipan snake venom with a needle."

"When did you die?" She still felt incredible.

“死于6月15日凌晨2:00到2：50之间。”

"How... is this possible? How did the murderer get into my house? The door lock of my house is unlocked with a fingerprint. Isn't the fingerprint unique?"

"It's very simple. You can copy your and your family's fingerprints online for 200 yuan. Some advanced hackers can directly invade your door lock without copying your fingerprints. However, we have inspected the scene and found no one entering Li Dacheng's bedroom. ." Jiang Yiming looked at her quietly, wanting to see her reaction.

"Could the murderer be able to fly?"

"This is impossible..." When Jiang Yiming said this, his cell phone rang suddenly. When he saw that it was Wen Xiaorou's call, he left the living room and went to the balcony to answer the phone: "Xiaorou, have you discovered anything new? ?”

"Yes, I checked the door lock of Li Dacheng's house and found that from 6:15 to 00:00 on June 03, the door was opened and closed three times, one of which was opened by Li Dacheng with his fingerprint at 00:00 , the second time was opened from the inside at 15:01, and the third time was opened from the inside at 50:02." "Is it possible that it was hacked?" Jiang Yiming knew that it was relatively easy to hack into the smart door lock. , ordinary hackers can do it.

"I checked carefully and found no trace of the door lock being hacked. Most hackers will leave electronic fingerprints, especially low-level hackers who hack into the door lock will definitely leave traces." Wen Xiaorou's tone was very sure.

"Okay, I understand." After Jiang Yiming hung up the phone, he returned to the sofa and sat down. He looked at Liang Nuanyu and asked, "Ms. Liang, I need to ask you some questions. You must answer them truthfully, otherwise you will be legally responsible. "Jiang Yiming suspected that she or her accomplices murdered Li Dacheng, because the door was opened from the inside twice, and she and her husband were the only ones at home.

"This is necessary. Of course I know that perjury is illegal." She frowned, as if she was thinking about something.

"Do you know what time Li Dacheng went to bed in the morning on the 15th?"

"He went to bed as soon as he got home. He said he drank a lot of liquor with the guests and was very tired, so he went to the bedroom to sleep without taking a shower." She replied softly.

"Is he sleeping and not eating?"

"Drink a glass of warm water and two alprazolam tablets."

"Are you sure there are only two slices?"

"Yes, I personally poured water for him and put two tablets of Alprazolam into his palms."

"You didn't tell the truth. According to the autopsy results, we learned that Li Dacheng took 8 to 10 tablets of alprazolam, which was 4 to 5 times more than the usual dosage. Moreover, the last thing he ate was yogurt."

"Drinking yogurt? I don't know, I really don't know. I saw that after he took alprazolam, he went to the bedroom to sleep. Maybe he thought yogurt could relieve hangover, so he got up again and went to the refrigerator to get yogurt. Want to drink?" She lowered her head slightly and said.

"You are still lying. We found a yogurt box from your trash can. It had your fingerprints and Li Dacheng's fingerprints on it. How do you explain it?" Jiang Yiming asked calmly.

"It's normal for the yogurt box to have my fingerprints on it. I put the yogurt in the refrigerator to refrigerate. My husband likes to drink cold yogurt." She thought for a moment and said.

"But we detected a high concentration of alprazolam in the residual yogurt in the yogurt box. How do you explain this?"

"I don't know that."

"Let me ask you another question. Has anyone been to your house after Li Dacheng went to bed?"

"No...it's so late. Who will come to my house? If my husband finds out, he will beat me to death..." She stopped here.

"If your best friend or female relatives and friends came to seek refuge with you late at night, would Li Dacheng know that he would beat you in the future?" Jiang Yiming knew that what she was subconsciously thinking about was that a man came to find her. This was psychological evidence.They once handled a disguised rape and murder case. The murderer was the husband of the deceased. He was afraid that his wife's private parts would be seen, so he covered them with clothes. From this, they determined that the murderer was the husband.

"This...if a woman came to my house, of course my husband would not blame me."

"Our technicians checked your door lock. The door lock recorded that your door was opened from the inside at 01:50. Did you let someone in?" Jiang Yiming knew that there was something wrong in her mind, so his voice rose slightly.

"No... I should have gotten up in the middle of the night to take out the trash. The trash in my bedroom hadn't been thrown away for three days and it was a bit smelly, so I got up to throw it out..."

Jiang Yiming had already seen that she was lying, because when he went to check her bedroom, there was a lot of garbage left in the trash can next to her bed. The suspicion of her collaborating with others to murder Li Dacheng increased: "After you threw away the garbage and returned to the bedroom, Didn’t you get up and open the door again?”

"No, absolutely not."

"But our technician told me that your door opened again from the inside at 02:50. How to explain this?" Jiang Yiming pressed on her step by step.

"It should be my husband who got up in the middle of the night to take out the garbage, right?" She continued to resist tenaciously.
