It was dinner time, and the dining car was overcrowded. Some people were even waiting for seats in the aisle of the carriage. When He Xiaohui received Dr. Qiao’s message, their meals had just been served. After reading Dr. Qiao’s message, He Xiaohui wanted to take a train.
You can also encounter a murder case, your luck is really incomparable.
After replying to Dr. Qiao's message, He Xiaohui paid close attention to the situation in the dining car while eating. Most of the people who came to eat in the dining car came in groups, and fewer people came to eat alone. Some of the people eating in the dining car talked loudly, and some
Conversation in low voices, those who come to eat alone often look at their mobile phones while eating.
He Xiaohui focused on observing people who kept silent, because no matter how mentally capable a killer or murderer is, it would be difficult for him to carry out his murder plan while talking and laughing.
A dark-skinned middle-aged man had his back to He Xiaohui and their dining table. This man would sometimes turn around and glance in their direction. He Xiaohui would also automatically ignore people who behaved like this. No killer would be that stupid.
Choose a seat with your back to the target.
An old man with white hair sat diagonally opposite them. He Xiaohui had an impression of this man. He should be the old man in Dr. Qiao's box. He sat at the door of the box for a long time in the afternoon. The old man lowered his head and ate in silence. He didn't
He was looking at his cell phone without raising his head and looking around, as if he was concentrating on something.
There are two rows of seats behind He Xiaohui, filled with passengers who came together. He Xiaohui had already observed this when she sat down.
Guan Jie's message was sent.
Guan Jie: Is it convenient? Do you know that there was a murder in the car?
He Xiaohui: It's inconvenient. I understand. Dr. Qiao has intervened and the identities of others have not been revealed.
Guan Jie: The case has been handed over to us. Do you need any help?
He Xiaohui: I don’t know the specific progress. I will ask Dr. Qiao to contact you directly.
After dinner, the four of them returned to the box together. Since a case had just been reported in the car, He Xiaohui followed Rumeng closely, observing the people around him carefully. When passing by the white-haired old man, He Xiaohui's peripheral vision
Noticed that the old man turned his head and glanced at them.
When passing the connection between carriages No. 2 and No. 3, the conductor had already cleaned the area, and it was no longer possible to see that a person who had been poisoned to death was lying here just now.
After returning to the box, He Xiaohui found an opportunity to quietly say to Rumeng:
"Don't go out alone. You have to call me when you go to the bathroom."
"Ah, what's the problem?"
"We haven't found it yet, so we'd better be careful."
"Okay." Duan Rumeng agreed.
After sending the body off the bus, Dr. Qiao remembered that the deceased's backpack was still in the box. He thought for a moment that it would be safer to go back to the box to get it himself, so he called the conductor and came to Car No. 2.
The white-haired old man and the woman were both in the box. They were sitting on the old man's bunk and talking about something. After the conductor opened the door, they stopped talking. The conductor invited the two passengers outside the box, and Dr. Qiao carried him alone.
The suitcase entered the box and closed the door.
Dr. Qiao put on gloves and lifted up the sheets on the deceased's bed. The deceased's backpack was lying quietly under the bed. He opened the lid of the trash can and found that the green tea bottle that had been thrown away by the deceased was still inside.
Dr. Qiao turned off the lights in the box, took out the multi-band detection light he carried with him from his suitcase, and began to check the fingerprints in the box. Under the illumination of the special light source, fingerprints that could not be seen under fluorescent lights were revealed, and the door handle
, there are more or less fingerprints on smooth objects such as desktops. Dr. Qiao used tools to extract these fingerprints one by one.
After returning to the mail train, Dr. Qiao began to look through the deceased's belongings. The wallet contained the deceased's ID card. From the ID card, it was known that the deceased's name was Huang Kangcheng, age 43, and a native of Haizhou City, Shannan Province. In the wallet
Dr. Riccio also found several business cards, which were printed with: Huang Kangcheng, deputy general manager of Haizhou Dream Clothing Co., Ltd.
Fantasy Clothing Company? Isn't this the company owned by Duan Rumeng's father? Thinking of this, Dr. Qiao immediately took out his mobile phone, took a photo of his business card and sent it to the group.
Dr. Joe: The deceased's business card.
Deng Ru: What a coincidence?
Ding Yiran: Is this person related to our case?
He Xiaohui: I asked Duan Rumeng, and she said she didn’t know anything about the company, and she didn’t know this person named Huang Kangcheng.
Deng Ru: Why did this person appear on this train?
Dr. Qiao: I once had a few chats with him, and he said he was on a business trip to Zhongjiang. I have his mobile phone here, and I will implement the matter immediately.
Dr. Qiao took out the deceased's mobile phone, unlocked it and looked through the deceased's call records. He found that the deceased's last call was at 7:35 in the morning when he received a call from Mr. Wang of Zhongjiang Tianfang. Dr. Qiao used his mobile phone
I dialed Mr. Wang's phone number.
"Is it Mr. Wang from Tianfang?"
"Yes, you are that one?"
"I'm from the Zhongjiang City Police Department."
"Ah, from the police station? Do you have anything to do with me?"
"Do you know a man named Huang Kangcheng?"
"Yes, I know you. I took him to the station at noon today, and he took the bus back to Haizhou."
"What is the purpose of Huang Kangcheng coming to Haizhou?"
"We have a long-term business relationship. He came here mainly to discuss future cooperation."
"When did he arrive in Zhongjiang? Did he only visit one of your customers?"
"He arrived the afternoon before yesterday and stayed at the Zhongjiang Hotel. We had dinner together the night before yesterday. He stayed in our company all day yesterday. We saw him off early this morning. He probably didn't go to see other customers."
"What time did he arrive at the train station today?"
"I sent him off. When I got to the station, I looked at my watch. It was eleven o'clock sharp."
"OK, thanks."
"Hey, what happened to him? Did something happen?"
"It's being kept secret for the time being. My colleagues will probably come to you again. Please cooperate with our work."
Dr. Qiao hung up Mr. Wang's call and immediately called Guan Jie.
"Team Guan, the deceased entered Zhongjiang Station at eleven o'clock. I would like to ask you to arrange for your colleagues to check the station's video."
"Okay, what details do we need to pay attention to?"
"It is currently suspected that the deceased was poisoned by drinking a certain brand of green tea drink. I remember that when the deceased first got in the car, there were bottles of green tea in the net pockets on both sides of the backpack. One bottle was opened and the other was unopened.
The poison is in the unopened bottle of green tea."
"Backpack? Green tea?"
"Yes, the key point is when did these two bottles of green tea appear in the deceased's backpack."
"Ok, I see."
"I will send you the photo of the deceased, the photo of the backpack and the photo of the green tea right away."
"Okay, I'll make arrangements right away and ask them to contact you directly."
After the call with Guan Jie, Dr. Qiao picked up the deceased's mobile phone again, looking for valuable information. From the chat records of the mobile phone, clues provided by work groups and friends circles, Dr. Qiao gradually sorted out Huang Kangcheng's basic information and
Work situation. He sent the information he learned to the group.
Huang Kangcheng is the senior deputy general manager in charge of business at Dream Clothing Company. He has been with Dream Company for twenty years. After the death of Dream Company boss Duan Qing, he is currently in charge of all the company's business relations.
It can be seen from the exchanges in the work group that the employees in the business department are currently very dissatisfied with Duan Ruhuan, complaining that she is indifferent to the company, which has led to the company's loose management and the inability to deliver orders, which has made the business department very embarrassed.
.
Because they controlled the company's survival, the business department forced and squeezed Duan Ruhuan and other departments, causing conflicts between them to become increasingly acute.
From the chat records, we can also see that Huang Kangcheng has close ties with several other garment processing companies, and often takes orders from Dream Company to other manufacturers. In addition, Huang Kangcheng is still negotiating with the bosses of the other two companies on how to acquire them.
Dream Company Matters.
Regarding the sale of Dream Company, Huang Kangcheng once had a conversation with Duan Ruhuan.
Huang Kangcheng: Mr. Duan, today I met Mr. Zhan from Kaiding Company. He asked me to ask you.
Duan Ruhuan: What happened?
Huang Kangcheng: He asked us if we had any plans to sell the company?
Duan Ruhuan: No.
Huang Kangcheng: I told him the same thing. He also told me that we can negotiate a price first, and it doesn’t matter whether we sell it or not.
Duan Ruhuan: Not selling.
Huang Kangcheng: Yes, you can't sell it. He also said that you can keep part of the shares if you want.
Duan Ruhuan: Are you here to be a lobbyist?
Huang Kangcheng: No, no, our company is doing well, why sell it?
Duan Ruhuan: Let me think about it.
Huang Kangcheng: Well, actually there are advantages to selling it, it saves you so much worry.
Duan Ruhuan: Got it.
Huang Kangcheng: You see that you are not in good health recently, so you should take a good rest.
Duan Ruhuan: It’s not over yet!
After Dr. Qiao posted this information to the group, He Xiaohui expressed her own opinions.
He Xiaohui: It seems that there is a conflict between Huang Kangcheng and Duan Ruhuan. If Duan Ruhuan knew Huang Kangcheng's true intention, it would be possible to get rid of him.
Dr. Qiao: Especially after Duan Ruhuan knew that he would not live long.
Deng Ru: If there is a possibility that she paid to kill Duan Rumeng, then there is a possibility of killing Huang Kangcheng.
Ding Yiran: It is said that people who are about to die have good words. How could she be like this?
Deng Ru: That was at the last minute. She still has some days left to live, so she might want to take revenge on everyone who has offended her.
While they were chatting in the group, Dr. Qiao found two more green tea bottles and observed them carefully under the light with a magnifying glass. This kind of green tea is not a carbonated drink, and there is no gas leaking out when it is opened. Because when the drinks are filled,
The temperature is high, and the bottle should be at a slightly negative pressure after cooling. If there is a sound of gas flowing when the bottle is opened, it should mean that you are sucking air inside.
Dr. Qiao posted a photo in the group, which was a photo of the mouth of a green tea bottle. Under the bottle mouth, there was an obvious mark of being scalded on the neck of the bottle, the size of a soybean.
Dr. Qiao: This mark is probably where the murderer injected the poison. After the murderer finished injecting, he squeezed the bottle with his hand, squeezed out some of the gas, and then used something hot to melt the plastic to seal it, so that the inside of the bottle was still negative.
Even if it is pressed, there will also be a sound when it is opened, which will not make people suspicious.
Ding Yiran: Awesome! Like it!
Dr. Qiao: After you get off the car, cut the mouth of the bottle open. You should still be able to see the pinhole from the inside.
He Xiaohui: Like! In this case, it is very important to find the source of the drink.
Dr. Qiao: When Huang Kangcheng got on the bus, I saw two bottles stuck on both sides of his backpack. I have asked the customs team to send someone to check the video at the station.
