The Underlying Reasons I Chapter 9

Police station.

"We've made progress this time. The blood drawn is much cleaner than last time." As soon as Ryan walked into the serious crime team's office, he threw the conclusion and autopsy report on the table.

"What?!" Several people in the serious crime squad were shocked and picked up the report to read it.

"Well, this time the murderer drew blood first and then killed the person, so this time the victim's blood was drawn very cleanly - or in other words, almost all of it was drawn."

"Hey, do you think that the case of Cao Weiguo and Li Yuzhong could be the same person?" Quentin said, "Both of them had their blood drained out. Such a weird way of death shouldn't be a coincidence, right?"

Sean looked at Ryan: "What do you think?"

"It's possible. After all, it's rare to draw blood from a person. Moreover, the murderer also has similarities in the way he treated the two bodies." Ryan said this and slowed down his speech: "However, if there is really one murderer, it means that the murderer is becoming more and more cruel. Because this time, he drained the blood of the victim alive..."

There was a chill in the meeting room.

"I think the key may still be in the blood drawing." Quentin broke the silence: "Blood drawing is such a troublesome thing, why would the murderer have to spend time and effort to drain all the blood? It's impossible that he really wanted to drink it!"

No one answered, but everyone was very concerned about this. Perhaps the answer to this question was the key to solving the case.

After a while, Sean looked up and asked, "Have you investigated the identity of the deceased?"

"We've found out," Jiang Li said this time, "The deceased is Cao Weiguo, 53 years old, and was the department director of the First Pharmaceutical Factory. He divorced a few years ago. Xiaohai found his ex-wife's address and is bringing her here."

Not long after, Chris brought Cao Weiguo's ex-wife Bai Yun to the police station. Bai Yun was younger than Cao Weiguo, and because of the proper makeup, she looked just over 40. Although Chris had told him about Cao Weiguo, her expression was very calm, but when he saw Cao Weiguo's body, he still shed tears.

After a while, Bai Yun wiped her tears and walked out. She calmly said to Chris, Sean and others who were waiting outside: Let's go.

"Weiguo is a good man," Bai Yun said in a calm tone with some fatigue in the reception room: "Although he has a strange temper, he has no bad intentions and is a good man."

"Cao..." Sean was about to call her Mrs. Cao, but suddenly realized that it was inappropriate. It was Bai Yun who spoke up: "Just call me Bai Yun."

"Well, we checked and found that Cao Weiguo's parents have passed away and he doesn't have any relatives in this city, so we can only notify you to come over."

Hearing this, Bai Yun smiled slightly bitterly: "Haha, even if there is, he will destroy it. Since he suddenly changed nine years ago, he has never lived a normal life. He is nervous all day long. Even my son and I can't stand it, let alone others."

"Nine years ago?" Sean heard the signs of a problem and asked, "What happened nine years ago?"

"I don't really know. Weiguo wasn't like this originally. He was a good talker and did a good job. But nine years ago, I don't know what happened. He suddenly changed. He didn't like to talk, always lost his temper, had many strange problems, often had nightmares in the middle of the night, and then couldn't sleep all night. Our son was only a little over one year old at that time. It was already very hard for me to take care of the child, and he became like this. I often lost my temper because of this, and I suspected that he had changed his mind, but he didn't explain. After arguing too much, he slammed the door and ran away from home. I couldn't stand it anymore, so I had to divorce him."

"You didn't ask him what happened?"

"Why didn't you ask? But no matter how I asked, he wouldn't tell me. At that time, I thought he had someone else outside, but when I asked him, he just said divorce. I thought he really had someone else, so I got divorced in a fit of rage. After the divorce, I moved away with my son, far away from the place we lived in. I didn't want to hear or see anything about him. A few years later, I accidentally heard people say that he had changed jobs and was said to be still unmarried. He would send money to his son regularly, but we never met again." At this point, Bai Yun's face showed some sadness: "I didn't expect that when we met again, he would..."

After listening to Bai Yun's words, everyone knew that Cao Weiguo's change was obviously not due to family matters, so the most likely reason was his work. So Sean asked, "You just said he changed jobs? What did he do before?"

"Doctor, he used to be a doctor at the Medical University Hospital."

"Medical University Hospital?!" Several people were shocked at the same time, and they looked at each other - it seemed that they had found the connection between the two cases.

"Boss, confirmed!" Quentin hurried into the office: "Cao Weiguo was indeed transferred from the Third People's Hospital to the pharmaceutical factory nine years ago. Before that, he was the chief physician of the Third People's Hospital's internal medicine department. And I also investigated Li Yuzhong by the way. Guess what the result is?" Quentin's eyes flashed with a brilliant light: "Li Yuzhong has not always been doing research. He also changed his career. He used to work in the hospital pharmacy. And he changed his career eight years ago - just a few months later than Cao Weiguo."

"It seems like something big must have happened in the hospital at that time." Felix looked at Sean.

Sean also looked back at Felix: "It seems that we should have another good chat with Dean Xu."

Medical University Hospital.

"Officers, is there any progress in the case of Dr. Li's murder?" Xu Xuewei asked.

"We are still investigating." Sean said, "We came here to ask Dean Xu why Dr. Li was transferred eight years ago."

Hearing this question, Xu Xuewei froze slightly. He adjusted his sitting posture unnaturally and asked, "Why do you two ask this?"

"To be honest, Dean Xu, we recently discovered another murder case, and the circumstances of the murder of the deceased were very similar to those of Dr. Li. And by coincidence, we found that both of them had worked at the Medical University Hospital before, and both were transferred nine years ago. Oh, Dean Xu may have heard of the name of the deceased, his name is Cao Weiguo."

When Xu Xuewei heard the name "Cao Weiguo", his expression suddenly changed. Sean and Felix did not speak, but just looked at Xu Xuewei, waiting for his answer.

"Oh, I remember now, there was such a person..." After nearly a minute, Xu Xuewei adjusted his expression and spoke again: "Dr. Cao was our internal medicine doctor at the time. He said he wanted to change his work environment, so he was transferred. As for Dr. Li, I actually explained to you last time that Dr. Li wanted to do research, so he transferred to another department."

"Is that so?" Felix said, "But Dean Xu, there are some things I don't quite understand. Cao Weiguo has become the director of the Department of Internal Medicine here, so how could he change jobs just like that? And he actually changed to a pharmaceutical factory and stopped being a doctor. And Li Yuzhong, we found out that he was just a doctor in a pharmacy, and he didn't seem to be from a prestigious medical school, so how could he suddenly become interested in research?"

Felix's tone of voice is always gentle and modest, but the sharpness beneath this modesty is often more difficult to cope with.

Xu Xuewei could no longer hide his awkward expression: "Everyone has their own pursuits. If they want to do that, I can't do anything about it." At this point he stood up: "Sorry, I have a meeting to attend later. If you two have nothing else to do, please go back."

This is a blatant form of chasing people away.

Sean and Felix didn't argue any more. They stood up and walked out. Before leaving, Sean turned around and said, "President Xu, if you remember anything, please contact us." At the end, Sean deliberately slowed down his speech. He said word by word clearly, "Don't worry, we will get to the bottom of these two cases."

Although the second chat with Xu Xuewei did not yield any substantial clues, it made one thing clear to everyone: Cao Weiguo was indeed related to Li Yuzhong's death, and both were related to something that happened in the hospital nine years ago. With this clear, everyone also had a clear direction for the investigation, and the next thing was to dig deeper in this direction. So, the next day, the serious crime team went to the procuratorate to apply for a search warrant. This time, the serious crime team went to the hospital without a word of nonsense, and directly took the files of the relevant parties back to the police station after signing the search warrant.

Boxes of documents were placed back on the table, filling up several desks of the serious crime team. Everyone looked up at Sean, waiting to hear him assign tasks.

"Okay." Sean put down the box in his hand and looked up at his team members: "Now we already know that these two cases should be related to something that happened in the hospital nine years ago. At that time, Cao Weiguo was in the internal medicine department and Li Yuzhong was in the pharmacy. So we focus on the cases that these two people handled together nine years ago, and pay special attention to the medical records of those patients who died or had serious disputes. Do you understand?"

"Understood!" Everyone immediately went their separate ways.

Although the direction has been made clear, when everyone actually started looking through these documents, they found that it was quite difficult.

"Hey, Felix, can you help me see what's written here?" Quentin pushed Felix next to him.

"Hmm?" Felix leaned over and stared at the place Quentin pointed at to identify it carefully: "It seems to be MsPG..."

"MsPGN, proliferative glomerulonephritis." A voice suddenly appeared behind the two people's ears, startling them. Looking back, it turned out that it was Su Mohan standing behind them, leaning his head to look at them. Looking behind them, Jason and Liam were also standing there, and each of them was holding two large bags in their hands.

Liam smiled and raised the bag in his hand: "The takeaway is here, does anyone want to eat fast food?"

"Me!" Quentin threw the folder and rushed over. The others realized that their stomachs were also empty. They looked up at their watches and it was already past eight o'clock in the evening.

"Liam, I really love you so much." Quentin said to Liam incoherently while wolfing down food.

"Haha, don't thank me. Just now, Brother Jin saw that the lights were still on here and guessed that you were working overtime, so he asked us to help order takeout."

"Ah! Brother Jin! I knew you were the best!" Quentin looked at Jason with tears in his eyes.

"Okay, eat quickly." Jason patted Quentin who was still making fun of him and smiled: "What are you looking at?"

"Hospital medical records." Felix replied: "Those two blood-sucking cases are likely related to something that happened at the Medical University Hospital nine years ago, so we are looking at the hospital's medical records to see if we can find any clues."

"Brother Jin, let me tell you, this job is so dmn hard!" Quentin complained loudly: "Are those words written by those doctors? dmn, it's a whole book! There are so many symbols, even if you can see it clearly, you can't tell what he wrote!"

"Doctors usually use professional symbols to indicate diseases or medicines when writing medical records. On the one hand, this saves time. On the other hand, it prevents some patients from taking the prescription directly to outside pharmacies to get the medicine, so that the hospital will not get commission." Su Mohan said.

"Hey, right!" Quentin suddenly thought of something: "Xiao Mohan, do you recognize these symbols?"

Su Mohan nodded honestly: "I read some medical books when I was free before, so I know a little bit."

"Oh my god, that's great!" Quentin rushed over immediately: "Hurry up and help me! I really can't understand these weird drawings!..."

Jason watched Quentin pull Su Mohan away with shining eyes. He smiled, picked up the lunch box in his hand, and walked to Sean who was still working on documents.

"Okay, take a break and eat first."

"Oh, thank you." Sean put down the folder in his hand, took the lunch box, and ate it mouthful by mouthful. I don't know if he was still thinking about the case, Sean ate very slowly, his brows were slightly furrowed, Jason noticed that Sean's hand holding the chopsticks was white and thin, with distinct joints.

"Is the case difficult?"

Hearing Jason speak, Sean nodded. He glanced at the large and small cardboard boxes in the room: "There are too many documents. It will take time."

"Just ask us if you need our help."

"Huh?" Sean was stunned for a moment, then reacted: "Isn't this a bit inappropriate?..." After all, this was his team's work, and it wouldn't be nice to trouble others.

"Oh, it's nothing. You don't understand those technical terms, so you are very slow in processing. Besides..." Before Jason finished speaking, Quentin called out: "Brother Jin! Can you lend us your little Mohan for two days?"

Jason smiled and raised his eyebrows at Sean, as if to say: See? How is it?

Sean unconsciously raised the corner of his mouth. These people...

With the technical support of the forensic team, everyone's reading speed has increased a lot. However, the content of the document is too much, and it involves professional content, so the speed can never be too fast. But what everyone didn't expect was that on the afternoon of the next day, they suddenly received another shocking news------ "Just received a report that Xu Xuewei is missing." Sean put down the phone and said seriously: "Moreover, he left a note admitting that he was the murderer of two vampire cases..."
