Serious Crime Unit 1

Chapter 47 Death of accomplice (6)
They summoned Ningbo to the criminal police team. Ningbo sat in the office with strong resistance. He refused to admit that he had committed a murder by subcontracting someone. He also accused them of unjustly accusing a good person. He wanted to go to the Discipline Inspection Commission to sue them for wrong enforcement of the law.

Jiang Yiming couldn't figure out whether he was disguising, but Wu Jiang thought he was a strong man on the outside and a gangster on the inside. Jiang Yiming thought for a while and said, "You said there was no package swap, so why are there only your and Achang's fingerprints on the bottle?"

"I gave it to Achang to drink. Of course it has my fingerprints on it."

"Besides you and Achang, was there any third party present?"

"No."

"If you think about it carefully, this will go a long way in clearing your name."

"No, really not. I remember it very clearly. Don't ask me anymore. It's all in vain. I definitely didn't kill anyone. If you treat me like this, it will affect my future!" He said angrily.

Jiang Yiming wanted to say: You, a prison doctor who can't even fulfill your obligation to cooperate with the investigation, are simply a scum of the police. What's the future?But he held it back, Jiang Yiming thought: If Ningbo did it, he had already thrown away the bottle, why put it in the trash can for them to check?And he left his fingerprints on it, which is not consistent with the behavior of a highly intelligent criminal.

Jiang Yiming said: "A few days before Achang died, did anyone visit your medical clinic?"

Ningbo glanced at him sideways, then closed his eyes, as if he didn't want to say anything.

Wu Jiang slammed the table and shouted: "Ningbo, you are still a prison doctor. Let me tell you, based on the insulin in the glass bottle and your fingerprints on it, we can send you to the detention center and let you try it." Taste what it's like to be a prisoner."

Ningbo's whole body was shaken and he opened his eyes, but his eyes became much softer than before.He said: "Oh, I remembered that in the days after Achang died, Dr. Liu Fei from the town came to my medical clinic every day. He would sit there for about half an hour and then leave."

"What are you talking about?"

"He asked me if I had any patients in the past few days. I said there were very few patients. Only Achang came to get injections for three days. He also saw Achang coming to get injections."

"Besides Liu Fei, has anyone else come to your medical clinic? Think about it carefully, every small detail is very important for us to solve the case." Jiang Yiming said.

In the public security school, the instructor once said that suspects and witnesses often tell the police that they have said everything they know and can no longer recall anything, but in fact, what they said is less than 20% of what is stored in their memory. , they will think that the remaining things are meaningless. A qualified police officer should keep this in mind: if you want to get all the information from them, you should take the trouble to ask them for questioning until they have no choice but to get rid of the police's entanglement. Consciously and voluntarily help to recall.

"No, my medical clinic is small and hot. No one wants to go to my place to suffer."

"Ningbo, the situation you mentioned is very important. It may clear your suspicion. Don't tell anyone about our search for you when you go back. Remember?" Ningbo nodded. They ended the interrogation and let Ningbo go back. After Ningbo left, Jiang Yiming called Warden Ye and said that Ningbo was suspected of murder. He asked for their help and that Ningbo was not allowed to leave Yangtze City until the investigation was clear.

Warden Ye hesitated for a long time before agreeing to assist, seemingly reluctantly.

No.70 Section [-]: Clever Murder
In addition to Ningbo being suspected, Dr. Liu Fei from Heping Town Health Center is also suspected of murder. He and Ningbo are classmates in medical school and they often interact with each other. He knows the killing effect of insulin. If Liu Fei wants to kill Achang, he will He tried every possible means to learn about Achang's situation from Ningbo, and then waited for an opportunity to take action. Achang happened to have a fever in those days and had to go to the Second Prison Medical Center for injections every day. The opportunity came. Liu Fei took advantage of Ningbo and Achang's inattention and took the antiviral orally. The liquid was replaced with insulin oral solution, thus achieving his murderous purpose. Of course, Liu Fei wore invisible gloves when doing this, so he would not leave fingerprints on the glass bottle.

They decided to meet Liu Fei for a while.

When Jiang Yiming, Wu Jiang, and Xiao Ke went to the Heping Town Health Center to find Liu Fei, the director said that Liu Fei had taken leave and did not come to work.They went to Liu Fei's home to look for her. Liu Fei's wife said that he was on a business trip to Shanghai and was sent by the health center.Why do the dean and Liu Fei’s wife have different opinions?Did he get wind of it and run away?If so, Ningbo must have tipped off the news, so Ningbo and Liu Fei may have committed the crime together!

Wu Jiang asked Liu Fei's wife to tell him Liu Fei's mobile phone number. Wu Jiang entered Liu Fei's phone number into his mobile phone and pressed the dial button. The system replied: The phone you dialed has been turned off. Please dial again later...

At this time, Jiang Yiming received a call from Warden Ye and said hurriedly: "Captain Jiang, it's not good. Zhang Caibao is dead. Come here quickly..."

"What? How is this possible? Are you kidding me, Lao Ye?" Jiang Yiming couldn't believe his ears and thought he heard wrongly.

"There is no joke in the army, come on -" After that, he hung up the phone.

It's incredible: in a closed cell, under the 4-hour guard of four armed police officers, Zhang Caibao actually died in prison!One wave after another made Jiang Yiming feel his head was spinning. He called Zuo Li and Luo Jin and asked them to rush to the Second Prison to investigate the scene, where he and Wu Jiang were waiting for them.They walked into the cell where Zhang Caibao lived and saw Zhang Caibao lying on the cement floor. His body was curved, his face was distorted, and his expression was very painful. His body was cold and stiff. He had been dead for at least 24 hours. It was estimated that he died of poisoning after lunch. of.

The spots on the corpse were bright red, and it was initially determined that he died of oxide poisoning.No fresh fingerprints or footprints were extracted from the scene. In other words, no one has entered this cell since Zhang Caibao moved into it. But how did the murderer poison Zhang Caibao?The first thing they thought of was Zhang Caibao's food. Jiang Yiming asked Xiao Fang, the prison guard responsible for checking Zhang Caibao's diet, to learn about the situation. Xiao Fang said: He had tested Zhang Caibao's lunch and boiled water and found no toxic ingredients.

"After lunch, is there anyone else giving Zhang Caibao something to eat?"

"No."

The armed police guarding Zhang Caibao also testified that except for prison guard Fang who brought meals and boiled water to Zhang Caibao, no one else sent food to Zhang Caibao.Jiang Yiming pulled up the surveillance video and looked at it, and the results showed that what they said was true.

Another case of invisible murder!Why is the murderer so clever?Jiang Yiming was able to kill Zhang Caibao under the tight protection of the armed police. Jiang Yiming felt that there was a mountain weighing him down and he couldn't breathe.

The autopsy report from the Forensic Medical Identification Center came out. Zhang Caibao did die from cyanide poisoning. However, the cyanide did not enter Zhang Caibao's gastrointestinal tract through the esophagus, but penetrated into the blood through the skin.Jiang Yiming didn't understand, so he Luo Jin said, "Can you explain how cyanide seeped into Zhang Caibao's blood?"

"If Zhang Caibao wears clothes soaked in cyanide and exercises indoors and sweats, the sweat and cyanide will mix with each other. When Zhang Caibao stops exercising, the pores will begin to shrink, and cyanide will penetrate into the skin along the pores. , and then reaches the blood, and the blood is then transported to the heart, which will lead to Zhang Caibao's death within 1 minute, and it will be too late to save him."

"Is it so evil?" Zuo Li asked.

"This is not evil, it's science. If you don't believe me, come and try it?" Luo Jin said seriously, and Zuo Li was speechless.

Jiang Yiming asked Luo Jin: "You mean there is cyanide on Zhang Caibao's clothes?"

"This is just a hypothesis. If we want to confirm it, we need to take back the clothes Zhang Caibao was wearing when he died and test them."

When they were transporting Zhang Caibao's body back to the autopsy room, for convenience, the staff took off Zhang Caibao's clothes and threw them away. This was a mistake. Jiang Yiming was worried that Zhang Caibao's clothes were being treated as garbage, so he called To Warden Ye, ask if the clothes Zhang Caibao was wearing when he died are still there?Warden Ye said that it was thrown into the trash can by the cleaner yesterday and he didn't know if it was picked up by anyone.

Jiang Yiming and Wu Jiang rushed to the second prison and searched in the trash can at the gate, but couldn't find it.

They found Mr. He who often picked up garbage at the gate of the second prison. They told the uncle that he had indeed picked up a piece of clothing and pants, and put them in a garbage bag without washing them. After saying that, he was going to get the clothes to show them, but Jiang Yiming stopped him. , Uncle He was a little confused, Wu Jiang explained: "Uncle He, you are lucky. If we don't come to stop you before you wash your clothes, you may be dead."

"Is there a ghost attached to my clothes?" Uncle He felt that Wu Jiang was scaring him.

"Perhaps more dangerous than ghosts, it is highly poisonous. Once it penetrates into the skin, it can send you to see King Yama in a few seconds." Wu Jiang said, and the uncle opened his eyes in shock.

After getting Zhang Caibao's clothes, they returned to the second prison and took all Zhang Caibao's clothes back to the criminal police team. After testing, the results showed that the shirt Zhang Caibao was wearing was indeed soaked with cyanide, and the other one was not. Cyanide was also detected on the shirt he wore.

The prison guard said that the two shirts were sent by Zhang Caibao's father the day before yesterday. "Tiger poison cannot eat its seeds." How could a father murder his son?It seemed that there was someone else, but Zhang Caibao's father had already returned home after taking care of the funeral affairs. His home was located in Yuanyuan Village, the northernmost part of the province, nearly 400 kilometers away from Yangtze City. Jiang Yiming asked Wu Jiang to go with him, and Zuo Li He asked unhappily: "Captain Jiang, why don't you take me?"

"It's not convenient for you to be a girl, it's too far."

"The last time I went to Xiao Xiaoquan's house, it was more than 300 kilometers away. What's the difference?"

"Last time you were lying on the bed in the village committee, didn't you sleep all night?"

"how do you know?"

"Your red eyes told me that you should look after the house." After Jiang Yiming fell in love with Li Yan, he wanted to minimize the chance of being alone with her.
