Chapter 23 Case Six: Fatal Coke (4)

Huang Yiwei picked up two cards instead of the two bottles of Coke: "Now let's talk about these two bottles of Coke. One bottle has not been opened and is still in the plastic bag that Guan Xiangdong carries." He put the two cards in succession.

The armrest box said: "There is a bottle missing. If he uses this bottle without drugs,

Coke replaced the Coke that Guan Zili drank that was laced with sleeping pills, which is what happened during our on-site investigation. Guan Zili drank the Coke that had sleeping pills and died. Guan Xiangdong exchanged the Coke that Guan Zili drank with another bottle of Coke.

One bottle, so there is no sleeping pill in the Coke left at the scene."

Captain Yan said: "You are saying that Guan Xiangdong poured out part of one of the two bottles and replaced the remaining half of Guan Zili's bottle. He used the other unopened bottle to pretend to deliver food and pretend not to know. In fact, he had already drunk it.

Then I knew Guan Zili was dead."

"Yes, that's what I mean." Huang Yiwei said more firmly, "This can explain why Guan Xiangdong bought two bottles of Coke."

"But why did the Coke bottle Han Ming drank also have Xiang Dong's fingerprints on it, and why was the bottle laced with crane crown red?" Captain Yan felt that there were too many things that were unclear and there were too many clues.

"Captain Yan, you forgot that Han Ming also has a bottle of Coke." Huang Yiwei reminded Yan Gang.

Captain Yan thought for a while: "Yes, Han Ming exchanged the Coke that Guan Xiangdong bought, and he got the bottle that Guan Xiangdong bought." Then he thought, "That's not right, that bottle has Heding Red in it, how is that possible?

Can you buy it in the supermarket?”

Huang Yiwei was silent for a while: "Supermarkets will not sell Coke that has been spiked with Heding Red to customers, so the person who spiked it with Heding Red is Guan Xiangdong himself."

Team Yan firmly objected: "Guan Xiangdong gave Hedinghong to his son to drink. How is this possible? What's more, Guan Zili died of sleeping pill poisoning in the end."

Huang Yiwei was also a little excited: "Captain Yan, Brother Yan! Apart from the motive for committing the crime, do you think there are any problems with my analysis?"

Team Yan gradually calmed down: "I admit that what you said makes sense. You are saying that Guan Xiangdong poisoned the Coke and prepared to give it to his son, but Han Ming replaced it with Coke laced with sleeping pills. This is a mantis stalking a cicada, Huang

The bird is behind."

"We have to make reasonable assumptions and cannot exclude any factors subjectively," Huang Yiwei said. Putting aside emotional and moral factors, Team Yan felt that his judgment was reasonable, but he couldn't accept it for a while.

Team Yan raised a new question: "If the poison is really from Guan Xiangdong, then where did he poison it? There are people present when checking out and when going out. It is unlikely, then there is only -"

"It's time to get the Coke!" the two of them shouted almost in unison.

The two got off the car separately and entered the supermarket again. The boss saw the two of them again and was too frightened to speak.

Team Yan asked: "How many surveillance cameras do you have in your store?"

The boss pointed with his finger: "There are four in total, one at the door, one at the counter, one on the west wall and one on the east wall." Team Yan and Huang Yiwei only checked the one at the door just now, and they immediately checked the surveillance camera near the Coke shelf. Unfortunately,

The angle was not good, so I couldn’t see clearly what he was doing, and it was blocked by the shelves, but I was sure that Guan Xiangdong stayed there for about two minutes. The boss also confirmed this. He felt that Guan Xiangdong was strange that day, and it took him a long time to buy a bottle of Coke.

time.

When they returned to the car, Huang Yiwei received a call from Cheng Liya. Cheng Liya said: "Guan Zili did have a paternity test, and the test was for Guan Zili and his son Guan Zihao. They are not biologically paternity."

Relationship. I checked the date when Guan Zili did the appraisal, and it happened to be the date when Miao Kai went to see Guan Zili.

The time of discussion. The reason why he didn’t open the door was that he was not at home. At that time, he was at the Paternity Testing Center of the First People’s Hospital. There was also an unexpected discovery. My classmate said that there was another report related to Guan Zili, but the applicant was Guan Xiangdong.

, the results confirmed that Guan Xiangdong and Guan Zili are not biologically related to each other."

Yan Gang and Huang Yiwei were dumbfounded. Huang Yiwei said: "Are you sure that Guan Xiangdong and Guan Zili are not parent-child relationship? There is no blood relationship between the three generations of grandparents. This is too weird. Is there any unexpected situation?"

Cheng Liya said: "I have asked similar questions. My classmate said that if someone has undergone hematopoietic stem cell surgery, which is a bone marrow transplant for leukemia, the DNA may change, and part of the DNA will be the same as the hematopoietic stem cell donor. Help from classmates

I checked the medical archives and found that Guan Zili had undergone similar surgery, which was done when he was 12 years old."

"That is to say, the paternity test report cannot prove that Guan Xiangdong and Guan Zili are not biologically related. Right?" Huang Yiwei asked.

"That's true." Cheng Liya said and hung up the phone.

"Now Guan Xiangdong has a motive. He believes that Guan Zili is not his biological child. Guan Zili himself has brought him a lot of suffering in terms of life and financial burden. He has every reason to kill." Huang Yiwei said, "I

It is recommended that Guan Xiangdong be summoned immediately and his home searched."

Team Yan still found it hard to believe: "As a scientist, Guan Xiangdong doesn't even understand that bone marrow transplantation will change blood type?"

Huang Yiwei asked Captain Yan a question: "You are an expert in fighting and firearms, but what about other aspects? You can't know everything, right?"

Yan Gang slowly calmed down and thought about his last visit. Guan Xiangdong's expression was very surprised when he learned that Guan Zili died of sleeping pill poisoning. He was more surprised than sad. He felt very strange at the time.

Team Yan finally made up his mind: "I asked Daqiang to rush to Guan Xiangdong's house with the search warrant and arrest warrant, and let the people from the technical investigation team act together." They rushed to the downstairs of Guan Xiangdong's house to wait for Li Jianqiang.

The car swayed forward, and Huang Yiwei suddenly figured it out. Han Ming wanted Guan Zili to drink the bottle of Coke laced with sleeping pills, probably to steal the paternity test report at night. But the problem is also here, Han Ming

Why steal the paternity test report? Who needs this report? Is he Guan Zihao’s biological father?

He explained his idea to Captain Yan: "Do a paternity test for Han Ming and Guan Zihao." Captain Yan agreed, and Huang Yiwei immediately called Cheng Liya.

20 minutes later, Li Jianqiang arrived. Guan Xiangdong was impatient when he saw the police coming again, and stopped Team Yan and others from entering. Team Yan showed the arrest warrant, and Li Jianqiang put handcuffs on Guan Xiangdong. After showing the search warrant, the search began

Expand. This is an apartment with three bedrooms and two living rooms. The decoration style is modern and seems to be more in line with the aesthetics of young people. Under these styles, there are some mahogany shelves filled with antiques and various handicrafts.

Team Yan emphasized: "Guan Xiangdong is an expert in cultural relic appraisal. There are many antiques here. Everyone must be careful when checking them."

Huang Yiwei came directly to the study room. Most of the shelves were antiques, and a few were books. There was a red brocade box on the bookshelf that caught Huang Yiwei's attention. He took the box and put it on the table, opened the lock, and

Inside was a necklace-like bead. He had checked information about Hedinghong and seen photos of court beads. Some officials in the Qing Dynasty

Guan Xiangdong knew very well that being with a king is like being with a tiger, so he hid the red crane crown in the chao bead in advance to be ready to end his life at any time to avoid more pain. He was surprised that there was actually a chao bead in Guan Xiangdong's study.

He thought to himself: "Isn't there really Hedinghong in these pearls?" He picked up the magnifying glass on the table and looked at the beads one by one.

When Chaozhu is worn, there is a small string of beads specially worn on the back of a person, called Beiyun. A gap was found on the largest bead of Beiyun Bead. Huang Yiwei tried it, but couldn't break it, so he tried twisting it.

I found that there was looseness in the gap between the two halves of beads.

There were signs of movement. He twisted it counterclockwise and found that it couldn't be twisted anymore. Then he opened it slightly and found red powder inside. Unexpectedly, there was a hole in the bead, and the red powder inside was no longer full.

Less than half left.

Huang Yiwei was very excited and shouted out: "Captain Yan, come here!"

Team Yan came in, took a look, and asked doubtfully: "What is this?"

Huang Yiwei gave him some hints: "Do you still remember the red powder that Pi Peng discovered?"

Team Yan thought about it for a moment: "Pi Peng? You said this is - Hedinghong?"

"It's very possible." Huang Yiwei restored the beads and put them in the evidence bag. "When I checked for the red crane crown, I saw a photo of the beads. It looks like a string of beads. The red powder inside

It may be the crane-crested red used by officials to commit suicide."

"Yiwei, I really have you! Arrest Guan Xiangdong immediately!" Captain Yan wanted to go out, but suddenly turned back: "Hurry back to the bureau, interrogate Guan Xiangdong, you must participate."

Huang Yiwei rushed back to the station, and Pi Peng came to him and reported a new discovery to him: "The Coke bottle found at the scene of Guan Zili's death had the deceased's fingerprints, but the fingerprint area was smaller and the lines were shallower. I did it repeatedly

Experiment, it should be that severe rigor mortis occurred after the death of the deceased, and the muscles and bones have lost their response to life. It should be

It was formed by someone forcibly pressing the hand of the deceased on it. If it was left by the deceased who drank Coke before he was alive, if you pick up a 2-liter bucket of Coke, the fingerprint pattern should be very heavy and the trace area will be large, and there will also be traces of fingerprints.

I have done experiments on this to produce deeper palm print marks, and the results are completely in line with my inferences."

Huang Yiwei patted Pi Peng on the shoulder and said, "Thank you for your hard work. Well done!"

In the interrogation room, Guan Xiangdong said: "You have locked me up here. My wife needs someone to take care of her food and daily life. You have to send someone to take care of her. My granddaughter Yuanyuan is about to get out of school and needs someone to pick her up."

Captain Yan said: "Your wife and granddaughter are innocent. I have sent our police there. Don't worry. Professor Guan, you are also a well-known expert and scholar. We will not call you without evidence. We hope we can

Let’s talk openly and honestly.”

Guan Xiangdong said coldly: "You are not bad, and you are a bit humane. You only have 24 hours to interrogate me. I don't know what you want from me. It must not be to appraise antiques, right? Since they are all handcuffed, at least I am

Criminal suspect. Then show your evidence and let me take a look."

"First of all, let's talk about why your fingerprints were on the Coke bottles found at Guan Zili's death scene and Han Ming's death scene?" Team Yan picked up the photos taken at the scene and the fingerprint identification report.

"What's so strange about this? My son's food is delivered to me every day. What's so strange about having my fingerprints on it? As for that Ming, I don't know him at all. Don't blame him!" Guan Xiangdong refused to admit it.

.

Captain Yan reprimanded him sternly: "The Coke bottle in Han Ming's car has your fingerprints on it. We have scientifically compared it. You can't deny it if you want."

"Science? If you talk about science with a scientist, then I will talk to you." Guan Xiangdong leaned back and said, "In our cultural relic appraisal industry, there is a saying called fake. I believe you have heard of it. You have been there many times.

It is entirely possible that if you pass by my house, you can take my fingerprints, make the same identification, and finally induce a confession from me."

Captain Yan was furious, pointed at him and said: "You - as a well-known expert, you actually said that the police tricked the confession and that our evidence was fabricated."

"Isn't it possible? You can tell yourself." Guan Xiangdong looked at Captain Yan and said contemptuously.

Huang Yiwei patted Captain Yan's arm to signal him to calm down. Captain Yan also realized that he seemed to have fallen into his logical trap, put his arm down and stopped talking.

Huang Yiwei spoke: "Professor Guan, you are a well-known cultural relic appraisal expert in China, and you have also been the director of Tianyang Museum. I would like to ask you a question." Guan Xiangdong also calmed down a little and sat up straighter.

Huang Yiwei said: "Tell us about the Chaozhu during the Qing Dynasty."

Guan Xiangdong was stunned for a moment: "This seems to have nothing to do with the case."

Huang Yiwei smiled and said: "I will make a judgment whether it matters or not. Let's just chat. One of my ancestors was an official in the Qing Dynasty, and there is a court bead hanging at home. I don't know much about it. I don't know what grade of official it is."

Yes, please tell me."

"Those who can wear court beads are generally civil servants of the fifth rank and above, military officers of the fourth rank and above, and conferred wives of the fifth rank and above. Of course, the royal family can also wear it, but the east beads and bright yellow ribbons can only be used by the emperor, empress and empress dowager.
