Profiler 2: Criminal Investigation Brigade

He Tang paused and said, "Xu Zhenzhen said that she would divorce Lao Fan, and asked me to divorce my wife and marry her. She is a woman who hooks up everywhere, how could I divorce and be with her! See Xu Zhenzhen I refused, so I said that I was perfunctory to her, and kept forcing me to have a showdown with my wife, or I would make trouble at school.

I, I was confused for a moment, and I was jealous of her and those men, so I did something wrong.I told her that the car at home was broken down, and I borrowed her BMW to drive for a few days, so I took the opportunity to put a balloon filled with carbon monoxide on her car. "

Why did you recruit all of a sudden?Jiao Yang had some doubts in his heart, glanced at Hou Xiyong, and asked suddenly: "Then where did you put the balloon filled with poisonous gas on her car?"

He Tang was taken aback, "It's just...it seems to be under the seat? I can't remember clearly."

Jiao Yang paused. To be precise, the balloon was placed in the interlayer of the seat cover.But it seems that there is no big mistake in saying that it is placed under the seat.

Jiao Yang deliberately asked: "Are you sure? I was at the scene at the time, and the balloon containing the poisonous gas was not under the seat. Think about it again."

He Tang panicked immediately, and stammered, "Oh, maybe... maybe it's in the trunk. I was so flustered at the time, I really can't remember!"

"Oh." There is a problem.Jiao Yang said: "Then where did you put the balloon in the car? Is it at your house?"

He Tang hurriedly said: "Yes, police officer. It was put in the underground garage of my house! Officer, you believe me, I poisoned Xu Zhenzhen, and it has nothing to do with others!"

But at this moment, Jiao Yang had already had clear doubts about his words.This is not a murder of passion. In the chaos, it is understandable that he can't remember how many times he stabbed the other party.This is a crime with a high IQ, and it took only a few days for the crime to occur. It is hard for him to believe that most people can immediately forget the specific steps of poisoning.

Jiao Yang said: "But what matters in judging a case is evidence, not that we will believe what you say. Professor He, we will verify your words as soon as possible, so be prepared."

The physical evidence side used the fastest speed to test the two sets of laboratory equipment found in He Tang's house.The first set has no trace of use, and the second set, that is, the one found in the basement, has sodium oxalate residues, which is suspected to be caused by the experiment of preparing carbon monoxide.

As soon as Jiao Yang came out of the interrogation room, Lu Yuanli came up to him and said, "Do you think this case will be solved like this?"

"do not think so."

Jiao Yang said: "I think He Tang's sudden confession of murder is to cover up something, and he just wants to take the blame for some people."

Lu Yuanli smiled and said, "I think so too. He confessed suddenly after seeing the second set of experimental equipment. What does this mean?"

The two said in unison: "Li Wenyi!"

Lu Yuanli said: "I read the file. Li Wenyi is a professor of physics at Yuanyang University. She is a highly educated person, and she has many laboratory projects. She has been married to He Tang for many years, and she knows a few methods for preparing chemical reagents. , is not surprising."

"Moreover, when He Tang saw the second set of equipment, he showed a very surprised expression. If this equipment does not belong to He Tang, who could it be? Of course it is Li Wenyi. As you said, there is a relationship with Xu Zhenzhen. The spouse of a man who infects a man naturally has a motive for killing. He Tang thinks that Li Wenyi did it. It is normal to want to take the blame for her because of the relationship between husband and wife, or the guilt of cheating, or considering children and other reasons. "

Jiao Yang couldn't help but put his arms around Lu Yuanli's shoulder and said, "Look, we still have such a tacit understanding!"

Lu Yuanli dodged to avoid him, spread his hands and said, "If there is a tacit understanding, there will be a tacit understanding, don't stretch your claws casually!"

It seems that there is still less feeding, and the mouth and hands are not soft!Jiao Yang curled his lips, from now on, I will feed every day, I don't believe it, I won't be able to go home!

"Team Jiao!"

Mo Ke hurried in and said: "We have a new discovery! Xiao Zhou and I took turns to watch the surveillance video of He Tang's residential area and the underground garage. There was no video evidence of He Tang putting balloons into the car. But we discovered one thing. Three days before the incident, He Tang’s wife, Li Wenyi, drove the BMW out alone at night and returned about an hour later.”

"It really is her!"

Jiao Yang said: "If you go out at night and go back and forth for an hour, plus the time to place the balloons. The place where the real carbon monoxide gas is prepared should be near He Tang's house!"

Through the intranet, the police searched all the real estate information under the names of He Tang, Li Wenyi, and their daughter and son-in-law, and found out that under the name of He Tang's daughter, there is a pre-marital house, which is only a dozen or so away from He Tang's home. minutes by car.

Jiao Yang led the team to the small house, broke through the door and took a look, not to mention all kinds of experimental equipment inside, as well as various medicines such as sodium oxalate, and the courier bag for buying medicines in the name of He Tang's daughter!

With these evidences, Jiao Yang went to see Li Wenyi who had been brought back to the bureau by Zhang Xianning.

Jiao Yang said: "Professor Li, I didn't expect us to meet again so soon. You used your daughter's name to buy oxalic acid and other medicines to prepare high-concentration carbon monoxide gas. Then use professional equipment to inject it into the rubber balloon used for experiments. , and then urged Professor He to borrow a car from Xu Zhenzhen, and then took the opportunity to put it in the interlayer of her seat cover. Am I right?"

"The interlayer of the chair cover? It turned out to be done like this, and it is indeed more clever."

Li Wenyi said indifferently: "Lao He and I both have experimental matters, and it is troublesome to obtain these dangerous reagents in school. I just bought some through private channels. Although it is indeed my fault, you can sue me for illegal Possessing dangerous chemicals, you can’t just say that I kill people, can you?”

Jiao Yang nodded and said: "That's true. It's just that your residential area is under strict surveillance. So you deliberately drove the BMW to the downstairs of the small house in the old community where your daughter lives, and released balloons. But maybe, you don't live in that community, and you don't know that there is a municipal project recently to renovate and add old communities that are not dilapidated buildings.

Therefore, that community has also fully installed cameras, and plans to install elevators in the near future.Therefore, the process of looking back and forth in Xu Zhenzhen's BMW to find where to start has been completely recorded by the surveillance video. "

"This……"

Li Wenyi finally showed a wry smile on his calm face, "Well, maybe this is the recovery of Skynet, which is not missing. I admit, I really wanted to kill her. That woman messed around and got On Lao He's head, I have quarreled with Lao He, but for the sake of my daughter, son-in-law and grandson, I don't care about them anymore.

Who knew, she would even come to my house!I installed a camera at home without telling him. I just wanted to get evidence, just in case.In this way, tell him not to divorce, or to have some advantages in the division of property in divorce.

Unexpectedly, they were actually photographed.You know what that woman said about me?She asked Lao He, do I look like a dead fish in bed?Lao He said, it is still pickled in salt water, it is not like you, it is as slippery as a loach!Hahaha, it's so funny!I want to see who is the dead fish! "

Hearing such words suddenly, Jiao Yang didn't know what to think.He touched his nose in embarrassment, and said: "Professor Li, even so, there is no need to kill people! You don't care about yourself, you have to think about your daughter and grandson, right?"

"Yeah, I'm so stupid!" Li Wenyi laughed hysterically: "It's really not worth it to kill someone like He Tang who looks serious and pious on the surface, but is actually full of men and women! It's too cheap! Fan Yiwen, do you think he doesn't want his wife to die? It's all over now, he can sleep and fly with his young student!

But at the time, I hated, I hated them.As soon as I saw the bed at home, I felt sick and wanted to vomit, and I just thought of the unsightly pictures I took, and their shameless words and laughter, and I couldn't care less about that much!

But, as you said, I still have a daughter and a cute little grandson, I can't be caught, let alone go to jail!So, I start planning.How can I get rid of that disgusting woman without anyone noticing.At the end of last month, I celebrated my birthday. After get off work, I went to the chemistry laboratory of the school to wait for Lao He, wanting to go out for dinner together.

It just so happened that the power went out at this time. When I opened the door and went in, I saw Yang Qing arranging the experimental equipment. She was thinking about a dangerous reagent bottle with a yellow label on it.Strangely, I was attracted by her expression and gaze, and subconsciously went to look at the reagent bottle, and found that it was a bottle of carbon monoxide.

I immediately remembered two news stories I had seen before, poisoning cars with carbon monoxide to kill people, pretending to be carbon monoxide poisoning caused by turning on the air conditioner.I started to make various preparations, bought experimental equipment and medicines, and asked Lao He to borrow that woman's car to drive back.

Lao He's thoughts, he was not at home for a long time, and he didn't find any problems with these, and he didn't even notice that I bought the test tubes and other things, and he helped me drive the woman's car back.As you said, I drove the car downstairs to my daughter's and studied for a long time, but I didn't succeed..."

"What did you say?"

Jiao Yang was startled and said, "You didn't succeed?!"

Li Wenyi lowered his head and said, "Yes."

Jiao Yang said anxiously: "You mean, you didn't kill the man? But both Xu Zhenzhen and Lin are dead!"

"Correct."

Li Wenyi smiled bitterly and said, "But I didn't kill the two of them. Someone beat me to it. Captain Jiao, do you know the density of carbon monoxide? It's 1.250g/l. You need to use an inhalation that can be disguised as an accident." unless you find two people to press them and breathe directly. Otherwise, in the closed space of about three square meters in the car, if you want to slowly reach a sufficient concentration imperceptibly, you need dozens of grams of carbon monoxide, that is, dozens of liters , this volume is very large.”
