Serious Crime Unit 1

Chapter 1023 Fatal Adrenaline (3)
Jiang Yiming felt that Wu Jiang's words made sense. Of course, because he had not yet fully understood the case, he was not as confident as Wu Jiang.They investigated the scene until 7 o'clock in the morning, and the scene was completed. Lu Yingying and Wen Xiaorou divided the surveillance video into two parts, each watched one part, and had finished watching the surveillance video.

On the way back to the team, Jiang Yiming asked: "Yingying, have you found any clues in the surveillance video?"

"Captain Jiang, the surveillance video is normal. No one has tampered with it, and there are no signs of intrusion. We watched from 7 o'clock yesterday to 12 o'clock. Except for Qiu Yinwan who walked into Room 1608 three times, there was no No one has entered room 1608, not even a bird has flown in." Lu Yingying's voice was a little hoarse, different from the usual gentle and sweet tone, maybe she had a cold.

"So Qiu Yinyin is the biggest suspect." Jiang Yiming believed in Lu Yingying and Wen Xiaorou's video investigation capabilities.

"Xiaorou and I think so too. I think it was Qiu Yinwan who injected the fatal potion into the bottle, causing the deceased's death. Of course, this is just my speculation without any evidence."

"I think we shouldn't speak too early. We should wait until Luo Jin's autopsy report comes out before holding a case analysis meeting. If everyone feels sleepy, go home and rest for a few hours and go to work on time in the afternoon."

"Captain Jiang, we are not sleepy. I am full of passion when there is a case." Wen Xiaorou said.

"It's great to be young, but I'm a little sleepy. Time is so unforgiving." Jiang Yiming sighed.

Wen Xiaorou covered her mouth and said with a smile: "It is said that a man of forty is like a flower, not to mention that you are only 39 years old, and you are starting to lament that your years are like running water?"

"'It's easy for people to be thrown away by the light, red cherries, green bananas', I didn't expect that I would be 39 years old in a blink of an eye, and I would soon be in my forties..." Jiang Yiming casually said one of Jiang Jie's words and looked out the window blankly. Passing by the tall buildings, I felt an indescribable feeling in my heart.

That afternoon Luo Jin produced Mou Pingjian's autopsy report.It turned out that Mou Pingjian died from an overdose of adrenaline.

"Death from adrenaline poisoning?" Jiang Yiming didn't know that this first aid drug could also cause death.

"Yes. On the surface, the deceased died of heart failure, but in fact it was caused by adrenaline. Adrenaline is a hormone and is a conventional drug for heart disease. This is the cleverness of the murderer. Excessive use will induce symptoms of adrenaline poisoning. Nausea and vomiting, chest tightness, palpitation, muscle twitching, elevated blood pressure, and even inability to breathe can occur. It can also lead to ischemia, vasoconstriction, and death."

"Did the killer want us to think the death was caused by a doctor's overdose?"

"Yes, epinephrine can be used for heart failure, but generally only 1 mg is injected each time, mixed with normal saline, and injected through a peripheral vein to ensure that the epinephrine can reach the heart and play its role. However, I am not sure what is left in the medicine bottle. A test was conducted on the liquid that was administered and it was found that 170 ml of liquid contained at least 40 ml of epinephrine. This was a serious overdose, exceeding the lethal dose by more than 20 times.”

"Can epinephrine be easily purchased?" Jiang Yiming asked.

"Epinephrine is a prescription drug that cannot be purchased in pharmacies. You need to go to a regular hospital or a tertiary general hospital and get a doctor's diagnosis certificate before you can buy it. Adrenaline is usually used to save people whose lives are in danger. Improper use can result in patient death, so purchase is restricted."

"So, the biggest suspects are doctors and nurses?" Xiao Ke asked.

"That's the theory. However, the Internet is now very developed. Even guns and drugs can be purchased online, not to mention adrenaline?" Luo Jin answered.

"Old Wu, have you compared the shoe prints and fingerprints you extracted from the scene with the database?"

"After comparison, there are no matching shoe prints or fingerprints in the database."

"Let's see, Lao Wu and Xiao Ke go to the city's No. 1 Civil Hospital to verify shoe prints, and see if they can verify fingerprints as well, and investigate Mou Pingjian's social background. Zhou Ting and I go to find Qiu Yin. Wan, she fits our profile of the murderer. Yingying and Xiaorou continue to check the surveillance video and expand the time." Jiang Yiming arranged the task.

Qiu Yinwan sat opposite Jiang Yiming and Zhou Ting. She was wearing a pink nurse uniform. She was tall and slender, with a small and flexible waist, like a willow swaying in the wind. Her skin was as white as a lotus root, and her eyes were big and bright, with a smile on her face. With a look of beauty on her face, she looked back with a different kind of charm. To be honest, such a woman should be able to make money by working in the entertainment industry, or as an anchor.

There was anxiety in her eyes, as if she saw her home on fire and was unable to put out the fire.She sat half-assed on the sofa, straightening her back and waiting for Jiang Yiming's question. "Xiao Qiu, don't be afraid. If we ask you questions, you just need to answer truthfully."

"Yeah." She nodded, and a lock of burgundy hair fell from her hat.

"Through the autopsy, we concluded that Mou Pingjian died from an overdose of epinephrine. You were the nurse who injected him with the medicine, so you are suspected of murder."

"I...why?" She was stunned after hearing this, looking very surprised, and then her eyes overflowed, feeling very aggrieved.

"We still need to conduct an in-depth investigation to know your motives. Do you know Mu Pingjian?"

"I don't know him. He and I are...people from two different worlds. How could we possibly know him?" she said firmly.

"This case is quite complicated. There is no doubt that Mou Pingjian committed homicide. Did you really check what kind of medicine it was before injecting him with it?"

"Of course, this is a principle that I must abide by. Although I have only been a nurse for two years, I know the working principles and procedures."

"You really didn't find anything suspicious. For example, did you find anyone suspicious going to room 1608?"

"I'm not sure because I have to walk around 11 wards."

"I have been hospitalized before. Patients usually go to bed after 10pm. Unless there are special circumstances, nurses do not need to do ward rounds."

"The truth is like this, but unfortunately, 6 new patients came in yesterday. Their conditions are all unstable, so the doctor injects them with medicine at night, so I have to take care of them. The services of the VIP ward are Very considerate and considerate...haven't you seen the surveillance video? The video shows that from 7 to 11:50 last night, no one went in except me three times."

"It is precisely because of this that you are the most suspicious person... I have another question for you. We found two pinholes on the rubber stopper of the physiological saline solution, one is a large pinhole and the other is a small pinhole. , have you ever used a small syringe to pierce the rubber stopper and then inject the medicine into it?"

"I injected captopril, cedilan, dopamine and dobutamine injections into the normal saline with a syringe, and then inserted the needle into the normal saline bottle. Therefore, it stands to reason that The rubber plug left four pinholes and a large hole for the medicine needle. However, when I injected the above four drugs into the saline, it was very accurate. Only one pinhole was left, and it was in the middle. . Therefore, the small needle hole is most likely covered by the medicine needle of the infusion tube."

"But the pinhole we found was on the edge of the rubber stopper." Jiang Yiming took out the bottle with one-third of the normal saline remaining from his bag and handed it to Qiu Yinwan for a look, "Look, is this pinhole? Did you insert it?" he asked, pointing at the pinhole.

"This is definitely not a pinhole pierced by me. I am very professional in injecting and have my own habits. It is absolutely impossible to deviate so much when injecting medicine. This pinhole seems to have been pierced by an unprofessional person, or pierced his body." People may be panicking, which is why there is such a big deviation." Qiu Yinwan said with certainty.

Jiang Yiming fell into deep thought: Are Qiu Yinwan's words credible?If she is not credible, how can she be proven to be lying?If she is the murderer, how can we get the evidence?

Table Ying is Mou Pingjian's wife. She came to the forensic center with her two sons to identify the body. As soon as she saw Mou Pingjian's body, she burst into tears. Her tears flowed like a floodgate, and her expression was confused and sad. Even in despair, her eldest son cried bitterly. Only the younger son did not quite understand how painful and unfortunate it was to lose his father, so he could only cry with his mother and brother, but he was not very sad.

Jiang Yiming wanted to talk to Zhuo Ying about who Mou Pingjian had offended?Hope to find clues from it, but she either shook her head or cried, and was very emotional, blindly begging Jiang Yiming to arrest the murderer quickly.Jiang Yiming thought that he could not communicate with her for the time being, so he just kept comforting her.

There was a man named Mou Pingxiong who was Mou Pingjian's cousin. He and Zhui Ying came to identify the body. He was the same age as Mou Pingjian and only two months younger than Mou Pingjian. They were closer than brothers. It could be said that they were inseparable. Apart from words, we have played together since childhood and shouldered the hardships and responsibilities of life together. He also invested 20 yuan in the scholarly bar.Therefore, Mou Pingjian's death was a big blow to him. However, a man would not shed tears easily, so he could only suppress his sadness in his heart, because he also had to appease Zhu Ying and his two nephews, and take care of Mou Pingjian's funeral.

After Jiang Yiming comforted Zhui Ying for a while, he returned to the office. As soon as he sat down, the office door rang. After he said please come in, the door was pushed open and it was Mou Pingxiong.He is taller and thinner, with bright black eyes that are gleaming with anxiety. He has better-looking facial features, but his forehead lines are deeper.

Jiang Yiming thought he might have something to say, so he asked him to sit down.
