Chapter 643

The next day, Wang Mengqi was called to the Bureau. Chen Shi and Lin Dongxue were in charge of asking him. Chen Shi said, "Mr. Wang, we have met again."

"If you have something to say, I have to work." Wang Mengqi looks impatient.

Chen Shi opens a laptop and plays a video. This is a surveillance copied from a supermarket opposite to Wang Mengqi's company. Looking at the video, Wang Mengqi's eyebrows are slightly raised, because the person who left the company on the video is himself, and the time is 4:00 p.m. on November 19.

"That day we asked your alibi. You said that you were using the company's landline to talk to Geng Qing, but we called up the monitoring outside your company and found that you left at 4:00 p.m. that day. Where did you go?"

Chen Shi continues to play the next video. It's the surveillance outside the park. Then he pauses and points to a man in black walking into the park. "I asked if you had this dress, didn't you?"

"I replied, that dress is very common, not only I have it, it can't be evidence."

"But we found your taxi record that afternoon in the Internet car Hailing company. The destination is the park. How to explain?"

Wang Mengqi bit his lower teeth and frowned.

"Are you thinking that there are many secrets?" Asked Chen Shi.

"I don't know how to ride a taxi!" He tried to quibble.

"It's a beautiful sophistry. It's like President Clinton said that finding semen on the Secretary's skirt doesn't mean there's a relationship between men and women. Shall we ask the driver to identify you?"

"I'm very busy at work. Sometimes my superiors have to cancel the previous plan on a phone call, so I don't know how to take the car when I call." Wang Mengqi forced the explanation with a cold sweat.

"We will check this point. I think it's such a forgery about your alibi. Your notice and Geng Qing's notice started from four o'clock. You pasted a mobile phone on the handset and microphone of the landline and used the landline remotely. In fact, when you put forward this alibi evidence, I was a little skeptical. Why do you use the company's landline to make phone calls? We investigated your record of using the office landline, and found that you usually only use it to make internal phone calls, but never call out. Does it mean that there is no silver here? "

Wang Mengqi seemed to be enraged and raised his chin. "If you have something to say, don't beat around the bush."

"We suspect you killed Geng Changle."

"Ha! With this, the park is open. Anyone can go there. Anyone who has been to the park is a murderer? What are my motives? "

Lin Dongxue gives him a paternity test result. When he sees it, Wang Mengqi looks obviously wrong. Chen Shi says, "Geng Changle is your father. I think he has told you the secret. He arranged a blind date between his daughter and factory director Wei and asked you for money to send Geng Qing to study. The purpose is to break you up. Geng Changle's feelings for you are very complex. You are his own flesh and blood. When he was young, he loved your mother and loved you deeply. He obviously liked you, but he could never let your brother and sister get married! "

"He likes me?" Wang Mengqi roared, "this old bastard knows who I am from the beginning. He has been asking me for this and that. Later, he developed to ask for money directly. It seems natural that he never did anything for me as his biological father, but now he comes to obstruct the relationship between me and Geng Qing. Until one day, he tells the truth that I am his own son, and Geng Qing and I are brothers and sisters. Everything is the same He did it when he was young, but now he wants us to pay the debt! "

"So you killed him?"

"No!!!" Wang Mengqi denied that his expression had betrayed him. "I didn't kill anyone, and I don't know how Geng Changle died. Besides, he is my father. How can I kill my father?"

"Geng Changle died of a poison. We have investigated that it takes 400000 yuan to buy the poison. You borrowed 400000 yuan of cash from the loan company and gave it to Geng Changle first. Then, at noon before his death, you gave the card to the person who sold you the poison. You exchanged it for the poison and killed people in the afternoon."

Being told the truth by Chen Shi, Wang Mengqi was sweating, but he was still brave. He smiled: "these are all your speculations. There is no matter. You said he was killed by poison. What kind of poison is it? You can't find out. That's sudden death! "

Chen Shi had expected that he would fight against the first army. After all, it was a nameless poison that cost 400000 yuan. Indeed, even if he was sent to court, he would be released for lack of evidence.

These four hundred thousand flowers are worth it!

Lin Dongxue secretly exchanged eyes with Chen Shi. At this stage of interrogation, Wang Mengqi was basically proved to be a suspect, but there was a big difficulty in front of him.

"Detention?" Lin Dongxue asked.

"What's the point of detention?" Today's goal has been achieved. Chen Shi said, "let it go first."

When he left the interrogation room, Wang Mengqi was soaked in cold sweat. Chen Shi said to him, "Mr. Wang, what did you do? You know what I know. Sooner or later, there will be evidence."

Wang Mengqi's conceit was aroused, and he stared at Chen Shi's eyes and said in a low voice, "just check it. No one can stop us from being together!"

After he left, Lin Dongxue said: "I expected it would not be so easy to plead guilty, but the clue is clear. Now concentrate all the efforts to check him!"! I'll report to the Lin team. "

"I'll go to Lao Peng's side and see if he has any progress."

Chen Shi came to the technical squadron and was informed that Peng sijue was not there. He found Peng sijue in the reading room. In front of him were several thick books on toxicology, chemistry and radiology.

Looking at Peng sijue's dark eyes and paler face, Chen Shi sat down beside him for about one night and said, "do you want to work so hard?"

"I may have thought of..." Pengsijue's voice was a little hoarse. He pinched the bridge of his nose and said, "go out with me to smoke a cigarette."

When he came to the corridor, Peng sijue took a cigarette with trembling hands. Chen Shi lit it for him and said heartily, "you spent the whole night in the library looking up materials? Think how young you are and stay up late like this? "

After exhaling a cigarette, pengsijue barely refreshed himself. He said, "I don't understand. I can't sleep steadily. When it comes to sleep, I just took a nap in the library. I got enlightenment in my dream. The toxic substance may be potassium!"

"Potassium?"

"It's a kind of radioactive substance, but it's also a trace element needed by human body. Banana contains potassium. If potassium exceeds the standard, it will cause arrhythmia and respiratory muscle arrest. If it exceeds the standard by one hundred or one thousand times, the heart will stop and jump instantly. In both cases of death, it was found that the blood potassium of the deceased exceeded the standard. The first thing I thought about was snake venom, because snake venom can produce this kind of Pathology, but I did spectral analysis several times, and no snake venom was found in deproteinization identification. Just in my dream, I got the enlightenment that the killer was potassium, a high-dose concentrated potassium, which is a substance of the human body itself. In addition, the killer set up a distractor, so I We can't test it. "

"It's great. It's worthy of being an excellent student in the Department of forensic medicine. I've come up with the answer. The suspect just left. Now I'm going to get him back and go through the formalities to arrest him!"

"No use." Pengsijue shook his head wearily. "It's just speculation. Although it's speculation that is infinitely close to the truth, it's still speculation. We can't prove what channel the potassium in the body of the deceased was ingested through, unless we can get a sample of that poison to prove the business relationship between the suspect and the poison maker!"

"So we still have to catch Xu fa?" Chen Shi said that the truth is close but has to make a detour. This feeling is really uncomfortable!
