In other words, Li Taida is unlikely to be the mastermind of the suicide.
When we left the interrogation room, Xiao Liu came back with Zhao Erming. According to the location Zhao Erming pointed out, the body of the dog that was poisoned that day was indeed found. Because of the remote location, no one picked up the dog's body. Potassium cyanide was also detected in the carcasses of dogs according to the Prussian blue method.
Zhao Erming didn't lie either.
At the beginning, only Zhao Erming and Li Taida got the potassium cyanide, and the others just participated in the process of stealing the potassium cyanide. Then, who secretly took the potassium cyanide
Three people have committed suicide, but the case so far seems to have no leads.
"Could it be that Gao Rui has already prepared it, and this matter has nothing to do with the case at all?" Guan Zengbin said: "You think, after Zhang Mingliang died, Gao Rui might have suicidal thoughts. The appearance of that person, It just strengthened his heart and did not provide Gao Rui with potassium cyanide."
I pulled my hair with my hands, and said slowly: "Since the murderer can persuade others to commit suicide, he must know that these people have suicidal tendencies. This is a problem. How did the murderer see that these people have suicidal tendencies?" Tendency? Could it be that the murderer would knock on every door and ask if you want to commit suicide?"
Guan Zengbin knocked his little head with his hand: "You mean, these people may express their tendency to commit suicide through the Internet or something? Then the murderer saw the information on the Internet, so he found them , and then persuade them to commit suicide?"
I slammed the table and said, "That's right, maybe that's it. I believe that the murderer is not a person who can hypnotize others, but started his actions after a detailed investigation. Judging from the frequency of recent suicide cases, The murderer should have investigated the information of many people, and then went to chat with them one by one."
Thinking of this, I immediately called Mary and asked her to investigate whether the deceased expressed thoughts of suicide on the Internet.
"It may take a lot of effort to chat one by one." Gu Chen said, "I think it's enough for this kid to run away."
Gu Chen's words reminded me, and I said, "By the way, take a map of Dongxing City. Now there are three people dead. Let's mark the places where these three people died, and maybe we can find the connection."
A map of Dongxing City was placed in front of us.
I marked the places where these three people died in red circles according to the chronological order of their deaths, and then wrote their methods of death.
The first to die was Wang Yiman. The community she lived in was called Xingyuan Community, located in the east of Dongxing City. Wang Yiman died by hanging himself. Remarks: He was wearing a white wedding dress.
The next person to die was Gao Rui, who lived in an apartment near Yucai Middle School, in the east of Dongxing city. The way Gao Rui died was by injecting potassium cyanide. Remarks: Dressed in a suit and leather shoes.
The latest deceased was Li Zhinan, who lived in Yingxin Community, which is also located in the east of Dongxing City. The way Li Zhinan died was by jumping off the subway. Remarks: There is also a briefcase that was knocked and flew to an unknown location and has not yet been found.
I circled all three locations on the map of Dongxing City, and an amazing coincidence appeared. The three people who committed suicide are all located in the east of Dongxing City. From the map, the distance is not very far. If you drive, the distance between the two is not more than two hours, so that is to say, they are all very close to each other. .
Such a short distance shows that the murderer who persuaded others to commit suicide has also been in the east of Dongxing City.
I pointed to the three red circles above and said: "Martin once said in his book that when a murderer has not been caught for a long time, there will often be an unconscious pride in his heart."
Guan Zengbin and Gu Chen looked at me with interest.
While looking at the three red circles, I said: "This is something that is inherent in human nature, just like our emotions. At this time, when we choose again, the location will often be farther away from our home." Getting closer."
I used a red pen to connect the three circles two by two to form a triangle: "For the first time, I tend to feel nervous, so I usually choose the place farthest from home, so that it is difficult for us to suspect him. And in the future, because of this mentality, he will feel more and more that we are incompetent, so he will be closer to home."
The two looked at me and nodded continuously. Gu Chen said, "Brother Wu Meng, you can do it. When did you secretly watch so many things? I think you are really a genius."
I shrugged: "I just spent your time drinking coffee on playing cards..."
Guan Zengbin gave me a blank look: "Don't be poor, what else do you know, tell me all about it."
I went on: "But there is another theory that goes against this view, another psychology that says the points should be equidistant."
Gu Chen nodded solemnly, and then said: "It feels a bit reasonable, but what is your conclusion? Can you guess where the next suicide will be?"
We all looked at Gu Chen, Gu Chen seemed to feel that what he said was wrong, stuck out his tongue: "If there are still people who commit suicide."
I sighed: "I think, as long as we don't catch the murderer, there will still be people who commit suicide under his guidance. After all, urbanites are under so much pressure now, no one wants to bid farewell to this world completely, and everyone When people say goodbye? I see, we still have to work hard.”
Gu Chen sat on the sofa and crossed his legs: "That's true. With the development of economic life, it seems that more people commit suicide. I don't know why. But I never thought about it, no matter what. No matter what happens, only living can have infinite possibilities and hopes. After dying, nothing can be changed.”
Gu Chen's words are quite good. In fact, when I was very young, I thought about committing suicide more than once.
If it wasn't for my fear of pain, I might have committed suicide as a child. This is also thanks to the fact that no one has popularized the knowledge of suicide to me, but until now, I have basically been able to accept this reality in my heart.
I can't choose who my parents are, but at least I can choose how to live according to my own wishes.
Guan Zengbin saw that the atmosphere seemed to be a little frozen, and she said: "I know, those heartless people never think about these things. Now let's get down to business, can you determine a range?"
Guan Zengbin's words pulled me back from my past thoughts, and I said, "Well, if these two statements are true, then the person who will commit suicide next time will not be inside this triangle."
As I said that, I pointed the inside of the triangle with my finger, which contained a large area, including Shuncheng Street, East Avenue, Sifeng Street and other places.
"Or at another point that would form a rectangle."
As I said that, I pointed to an area outside the triangle: "This is it!"
The above shows the Nylon Road area.
If there is a next time, this place should be the place where he will commit suicide next time.
Gu Chen stood up and said, "I'm going to make a call now and tell the people in this area to pay more attention recently, maybe there will be a suicide case here, let them be more vigilant."
"Go ahead," I said.
As soon as Gu Chen walked out, Xiao Liu walked in. He said, "Wu, Li Zhinan's briefcase was found, and it was knocked out by the subway. Later, the staff found it in a corner."
"Really?" I said, "Take a look, what's inside?"
Xiao Liu said: "The briefcase was smashed. I don't know what's in it. Maybe it's just some documents. The strong momentum tore everything inside, but I found a few broken ones." .But whatever is in the briefcase probably has little to do with the case."
While talking, Xiao Liu showed me the few documents that had a corner left. There were some bank and other things written on them, and there were too many missing, so I couldn't see anything. However, we have investigated Li Zhinan's background. He is a staff member of a financial company. This should be Li Zhinan's job and has nothing to do with the case.
Xiao Liu continued: "But the matter of potassium cyanide is over here. We should continue to investigate in that direction? Potassium cyanide was divided into two pieces, and one was given to Li Taida. He used potassium cyanide in into the beer, trying to poison his father to death. The other piece was in the hands of Zhao Erming, who poisoned the dog to death."
I pulled my hair and said, "A small piece of this thing can poison people to death. They all have one-sided opinions. We don't know how much they used and how much they left in the end. Besides, must it be divided into two pieces?"
"You suspect other people?" Xiao Liu said, holding his cheek, "Leave this matter to me, and I'll check it out."
