I don't know why Jiang Xiaochun did this, but judging from the rough situation now, Jiang Xiaochun seems to be hiding something, but he doesn't look like a person who has been frightened crazy. If a person who has been frightened mad is still in such a good complexion and in such good physical condition, then I would rather be a lunatic.
But looking at Mother Hu's earnest expression, since I don't know what Jiang Xiaochun is hiding, it's better not to say it first. After all, Jiang Xiaochun used so much effort to pretend, when I expose it, it may not be good for anyone.
I nodded and said to Mother Hu: "Don't worry, the investigation is almost done. If the murderer is caught, you will be notified."
Mother Hu sighed heavily, and then said: "Okay, I, I will wait for your news."
I nodded.
When I walked out of the door, I turned around and asked Mother Hu, "Do you regularly open the windows to ventilate that room?"
"What?" Mother Hu asked, "Which room?"
"It's nothing." I shook my head and said, "That's it, we may contact you again in the future."
The aunt who accompanied us in seemed to want to chat with Hu's mother, so she didn't follow us down. Only Zhao Mingkun and I were in the corridor. Zhao Mingkun didn't seem to understand what I was going to do, so he was very puzzled, so he asked me in the corridor: "What did you see?"
I nodded, and said decisively: "From my observation, that Jiang Xiaochun must be pretending to be crazy."
"Pretending to be crazy?" Zhao Mingkun asked, "How did you find out?"
As I walked down, I opened my mouth and said: "The aunt said that Jiang Xiaochun has one more problem. She only eats leftovers from other people's meals, and she only drinks water from the running tap. From the surface, it seems that there is something wrong with her brain. Something is wrong, I don’t eat hot meals, I insist on eating leftovers, and I insist on drinking cold raw water, but in fact, there is a deep-seated reason behind this.”
"What?" Zhao Mingkun asked me.
"Afraid of death!" I then replied: "The food that others have eaten means that there is no poison in it, and the flowing water means that there is no poison in it either. It's not that she doesn't eat, she eats and sleeps, it depends on her physical condition. Look, there is no problem at all. If it is really crazy, it must not be in this state."
Zhao Mingkun rubbed his chin with his hands, and said slowly, "It makes sense."
I continued: "That's right, I don't know if you noticed a detail. There is a bookcase in Hu Xiaoxue's room. The books in the bookcase are very neat, except that there is only one book that is thrown in casually. There is such a bookcase at home. For big things, Mother Hu doesn't even want to clean the house anymore, so why would she be in the mood to tidy up the bookcase? Then the cabinet has always been so tidy. But there is only one book that is not in order, which proves that someone turned it over later."
"You mean that Jiang Xiaochun read that book?" Zhao Mingkun asked again.
I said: "There is another detail. When I went out, I asked Mother Hu if she had the habit of opening windows for ventilation, but Mother Hu didn't know what I was talking about. This means that Mother Hu did not open the window at all. If Mother Hu didn't open it, then it must have been Jiang Xiaochun."
I looked at Zhao Mingkun, and continued: "A person, she hides in a room, reads a book when she is free, and remembers to open her window for ventilation, do you think this is something done by a lunatic? She She also feels bored when she is looking for something to do by herself. So, she is hiding."
"If that's the case, I can guess what it is." Zhao Mingkun said: "If there is someone she wants to hide from, I don't think there is anyone else except the murderer. She thought she didn't say anything , thought that if she was crazy, the murderer wouldn't have any thoughts about her, right?"
I snapped my fingers and said, "Then there is a problem. At the beginning, Jiang Xiaochun, after Hu Xiaoxue died, she said that there was a ghost coming back. But from our current analysis, she was afraid It's not a ghost at all, but a living person, and it's the murderer who is afraid. Then why does she know that the murderer is coming to kill her?"
"So Jiang Xiaochun is hiding something?" Zhao Mingkun said.
We have already walked out of the building, I looked at the sun in the sky, and said to Zhao Mingkun: "That's right. Jiang Xiaochun must know something tricky about what happened seven years ago. She and Hu Pei are too strange, too fast. I don't know if you have noticed a strange behavior of mine."
Zhao Mingkun nodded and said, "Of course I know, you asked for her ring? Is there any problem with the ring?"
"Raise a finger." I said to Zhao Mingkun.
"Huh?" Zhao Mingkun frowned even deeper.
"I mean, if you take off the ring frequently, you will naturally feel the friction. I have seen Jiang Xiaochun's wedding ring, and the inside of the wedding ring is almost smoothed, and the words on it can't be seen."
"But!" I said again: "There are quite a few stains on the outside of the ring. What does this mean? It means that the outside of the ring is rarely rubbed. Let's imagine why Jiang Xiaochun often takes off his ring. ? It can be inferred that Jiang Xiaochun should have someone outside."
"What?" Zhao Mingkun didn't seem to believe it.
I said, "Judging from her appearance, Jiang Xiaochun doesn't seem to be very sad for her husband, or even for her daughter. I think there must be something tricky about it. When Jiang Xiaochun and Hu Pei got married, It shouldn't be that simple."
"Then where should we go to investigate?" Zhao Mingkun asked.
I said, "Let Sister Mary check it out. If she knows a person's information, Sister Mary can find out a lot of things. As long as Jiang Xiaochun has contact with others, she can find out a lot of things."
"Mary." Zhao Mingkun seemed very moved, smiled and said, "We can be regarded as old friends."
And at this time, Gu Chen's phone rang in a timely manner.
"Gu Chen?" I said.
"I found the information of the person you want." Gu Chen heard my voice, and said without the slightest hesitation: "The name of the person you want to check is Deng Xuemei, female, and she is thirty-two years old. She is still Single, resigned from a pharmaceutical company a few months ago. Seven years ago, she graduated from Dongxing University as a student in the Department of Bioengineering."
After hearing Gu Chen's words, I already had the answer in my heart.
"Go on." I said.
Gu Chen's voice came out again: "According to Sister Mary's investigation, this Deng Xuemei's family conditions are not good. Her father suffered from a strange disease when she was in middle school. At that time, he didn't take care of this disease even though he had lost all his wealth. . Whether it was seven years ago or now, it was a terminal illness, basically incurable."
"At that time, Deng Xuemei's family was in good condition. It wasn't considered rich and powerful, but it was okay to describe it as a well-off family. But since her father got the disease, Deng Xuemei's family situation has been deteriorating. Later, After her mother left one night, she never came back."
"At that time, Deng Xuemei was going to school while taking care of her father. But every day became more and more difficult. Of course, Deng Xuemei also struggled and was admitted to a good university with her own efforts. It's just that Deng Xuemei had no money and no way to get a loan, but later she still Some kind people helped Deng Xuemei."
I nodded, I guess I can guess what happened next, and I said, "I know who it is. Later, a girl named Lu Zhiqiu sponsored Deng Xuemei, right?"
Gu Chen paused, and said, "That's right, it's a girl named Lu Zhiqiu. According to Sister Mary's investigation, before Lu Zhiqiu's death, she has been sponsoring this female student named Deng Xuemei since the second half of her freshman year. Every month, I will give girls 1,000 yuan without asking for anything in return."
"However, it seems that there was no money for a month." Gu Chen continued: "That is the last year."
"I know that." I nodded.
We have a better understanding of what happened later. At that time, Lu Zhiqiu borrowed a lot of money because he wanted to buy a dog, and Lu Zhiqiu was cheated in investing, so basically there was no extra penny at that time. So that month, Lu Zhiqiu really had no extra money for Deng Xuemei.
I already have the answer in my heart. The doctor told me before that students who study medicine and biology, chemistry is a compulsory course. And Deng Xuemei is a student majoring in bioengineering. If there is anyone who can kill people with precise amounts of chemical drugs, then Deng Xuemei is undoubtedly one of them.
In terms of time, Deng Xuemei resigned from her job a few months ago, which shows that Deng Xuemei has enough time to commit crimes. In terms of the motive for the murder, Lu Zhiqiu had supported Deng Xuemei without asking for anything in return for several years, and it was only natural for Deng Xuemei to take revenge out of gratitude. Judging from the method of killing, Deng Xuemei was a student in the Department of Biology, and preparing some basic chemical poisons was a very common thing for Deng Xuemei.
And the person I thought was the murderer was this person.
"So." I continued to ask: "Have you found out where Deng Xuemei is now?"
Gu Chen said: "Is this really the case, but we found out Deng Xuemei's original home. But her father passed away a few years ago, and now I don't know if Deng Xuemei still lives there. I will send you the address later, if you can If so, are you going to see it?"
"Okay." I said, "One more thing."
