"You give me a hint." As soon as Tang Hongye heard this, he immediately came to his senses, the investigation has progressed to this point, the approximate range of suspects is already known, and there are people with sufficient motives to commit the crime, they have basically been investigated, and now Du Juan said that there is a new perspective, Tang Hongye is of course very interested.

"We didn't know that the murderer chose such a killing method to be unsafe, why did he do it, and we can understand that the two detergents mixed together will produce toxic [HX] gas, and the concentration will be high enough to produce a fatal result, which should also require a certain cultural background." Du Juan had no intention of selling Guanzi, so he told Tang Hongye his thoughts: "But from another point of view, it makes sense why you chose such an unsafe way to commit murder." The relationship between the murderer and Leng Zhiqiang is far from being close enough to poison his diet, and there is also a relatively obvious gap with Leng Zhiqiang in terms of physical fitness, and he knows that the way in which the two cleaning liquids can be mixed to produce toxic [HX] gas may not come from his own knowledge and cultural background, but hearsay, or this kind of news report. ”

"Well, this does make more sense, because generally speaking, whether it is hearsay or news reports, it is usually to attract attention, especially emphasizing the most serious consequences, so if the viewer does not know enough, will think that the mixture of these two cleaning liquids is a deadly poisonous [HX] gas." Tang Hongye nodded, and after Du Juan said this, he also felt that the previous question had been reasonably explained.

"Didn't we all mention it just now, and it seems a little strange that Gao Lanna was suddenly sent to the hospital at this juncture? At first, I thought it should be Wei Huili who wanted to protect her daughter, but now I still have this opinion, but how to achieve the purpose of protecting my daughter, maybe my current thoughts are not the same as before. Cuckoo sighed, "Originally, I thought it was my daughter who was more suspicious, but now I think it's my mother." Perhaps she decided to send her daughter to the hospital for systematic treatment, hoping that her daughter could recover physically and mentally as soon as possible, so that in case her real affairs were revealed in the future, she could no longer continue to take care of her daughter, and Gao Lanna would not cause too serious life difficulties due to psychological problems, or even mental problems. ”

Tang Hongye was a little worried: "What are Wei Huili's words...... Her profession and murder methods are quite harmonious, using local materials, and it is reasonable to directly and indirectly know that those two things can cause death, but there are no witnesses, and there are no fingerprints and footprints left at the scene, how can she obtain direct evidence? ”

Du Juan thought for a while: "If it is really Wei Huili, then the safest and least noticeable thing she carries with her may be her profession." Do you remember her cleaner's uniform? Let's consider the time when Leng Zhiqiang may be killed, how long is it until Wei Huili's work time? Maybe you can bet that if she still needs to rush to work after the fact, she may wear a uniform, so that the recognition is still relatively high, even if she can't remember the specific appearance, people may still be impressed. Don't forget, there was a person who said before that he had eavesdropped on Leng Zhiqiang's house and bumped into Gao Lanna, that is, he was still at home at that time, and I don't know if he also saw a cleaner near his residence. ”

"Yes, no matter what, it's always right to try, I hope this guy can play a little bit of a role at this time, and have a little value!" When Du Juan mentioned this, Tang Hongye also remembered this former roommate of Du Juan, who was almost left behind by them because of the clear identity of the deceased.

It took a lot of effort for the two of them to find Zhu Junhao again, not because of anything else, but because the contradiction between Zhu Junhao and Mao Yaxuan escalated, Mao Yaxuan seemed to be moving the real character this time, calling many brothers and brothers who didn't know if they were really related, and they had to teach Zhu Junhao a lesson, so Zhu Junhao had to hide in Tibet, so as not to suffer a meal of flesh and skin, and when he was found by the cuckoo, he was hiding in a small hotel.

"I knew it! None of these people are reliable! If you can find me, Mao Yaxuan will definitely be able to find me when you turn around! Zhu Junhao was also a little dumbfounded when he saw the cuckoo and them coming to the door, and after coming back to his senses, he cursed, "One by two, they said that they would keep it secret for me, but others sold me after three inquiries and two inquiries!" ”

Du Juan didn't sympathize with any of his suffering, but told him when Zhu Junhao bargained with them and asked them to provide protection, he could go directly to the police station to report this kind of thing, she and Tang Hongye had no position to intervene directly, Zhu Junhao estimated that he didn't have much hope in the first place, just tentatively asked, and when he saw Du Juan say this, he didn't continue to beg her, and cursed a few words of Mao Yaxuan in a low voice, which turned to the topic.

"I really saw a woman that day, wearing a cleaner's clothes," he said to Du Juan and Tang Hongye, "At that time, I had just left, and when I got downstairs, I saw such a woman, quite old, looking like she was in her sixties, and she entered our unit." I thought at the time, in this old and dilapidated community, there is no cleaning outside, can anyone who lives in this building be able to afford part-time workers? If you were willing to spend that money, you wouldn't have to live in that kind of old and dilapidated house! I didn't think much else about it at the time, so I left. ”

"Do you remember what the cleaner looked like?" Tang Hongye asked him, and then took out several photos of middle-aged and elderly women wearing cleaning uniforms prepared in advance, and asked Zhu Junhao to identify them.

Zhu Junhao took the photo and only glanced at it, and immediately picked out the photo of Wei Huili: "It's her, it's her!" I remember! The clothes are all the same, exactly the same! She was wearing a big padded jacket at the time, but she was wearing an open placket, so she could see the cleaning uniform inside, this old lady was walking in a hurry, carrying a plastic bucket in her hand, and there were rubber gloves and bottles and cans in it, and I almost collided with it, and I was hit by her broken barrel, if I hadn't rushed away, I would have turned my face. ”

"Didn't she react or say anything when she bumped into you?"

"No! Otherwise, if I hadn't hurried away, she was an old lady again, and I would have been in a hurry! What the hell, how can there be anything like this! If you hit someone, you don't hum it! Zhu Junhao replied.

Du Juan and Tang Hongye confirmed to him again and again, and Zhu Junhao always gave a very firm answer.

After leaving the small hotel, the two of them went back to confirm several possible routes from Wei Huili's night shift to the scene of the crime through the map, and confirmed the road traffic surveillance video of the closest to the scene of the crime, and the two of them communicated with other people in the team, really found Wei Huili's figure from one of the roads, not only that, but the two of them also sorted out the shops that had captured Wei Huili's image on that route in the order of the route, although it cannot be directly determined that Wei Huili must have left from the scene of the crime at that time, but it was also eight or nine.

How did Wei Huili arrive at the scene of the crime, they did not find direct video evidence, Tang Hongye speculated that Wei Huili should have taken a taxi or the like to go directly to the unmonitored area near the community, as for why she didn't choose the same taxi when she left, there may be many reasons, or to save money, or just planned a murder, so the whole person is very flustered, as the so-called thief is weak-hearted, Wei Huili is afraid that taking a taxi will let the driver see that something is wrong, so she simply walked away.

Tang Hongye's second speculation is still quite tenable, because in the video clip of Wei Huili leaving, it is not difficult to see that her whole face is extremely solemn, her steps are hurried, and she looks very uneasy.

But these are not enough, Du Juan and Tang Hongye conducted another investigation on Wei Huili's work background, and found that she had received 10,000 yuan in compensation from her original employer in a previous job. Du Juan decided to start here, and learned that when Wei Huili was doing cleaning work in that cleaning company, she was sent to the hospital for medical treatment because she mistakenly mixed the two detergents, causing dizziness, chest tightness, shortness of breath and other adverse symptoms, and then because the company did not conduct safety training for employees in advance, the company paid Wei Huili 10,000 yuan in compensation as treatment costs, but at the same time, Wei Huili also lost that job.

This harvest was so important to the cuckoos that everyone was excited, and then Tang Li went to the hospital where Wei Huili was treated, and it was confirmed by the hospital.

Although none of these pieces of evidence can be regarded as very strong direct evidence, at least they have put Wei Huili's suspicion in a very clear position, so they don't want to continue to waste time, so as not to make trouble, they came downstairs to Wei Huili's house one evening, and it didn't take long to wait for Wei Huili.

Wei Huili looked extremely haggard when she came out, in just a few days, she seemed to have lost a lot of weight, her eyes were blank and she walked out, and when she met with Du Juan, she was not able to recognize them immediately, and was stopped by Du Juan's hand, and then raised her eyes and looked at the person in front of her seriously.

As soon as she saw who it was, Wei Huili's face suddenly changed, her cheeks twitched irrepressibly, and then the person also shook like chaff, but there was no surprise reaction at all.

"Wei Huili......" Du Juan took two steps forward and opened his mouth to explain his intention to Wei Huili.

Wei Huili didn't wait for her to speak, she directly stretched out her hand to stop her: "I know, I'll go with you, you let me slow down, I'm ...... I'm on my feet now, nauseous, and want to throw up...... You tell me to slow down, and I'll be fine for a while......"

The cuckoo sighed, didn't rush her, and stood by and waited patiently. Wei Huili slowly squatted down, sifting chaff for a long time, retching a few times from time to time, looking at the ground in front of her with two eyes, and after a long time, she stood up in despair and nodded to the cuckoo: "I'll go with you." ”

Wei Huili stood up and followed the cuckoo towards the parking place, only a few steps before her feet became weak, fortunately she was pulled by the cuckoo's arm from the side, otherwise this fall would not be too light.

On the way to the public security bureau in the car, Wei Huili was unusually quiet, giving people the feeling that the seat was not a living person at all, just a puppet, until she sat in the interrogation room, she seemed to finally come back to her senses in a trance and realized where she was.

"Do you have to inform my eldest daughter about me after that?" Wei Huili asked Du Juan and Tang Hongye before they could ask questions, "Then can you help me bring her a message, just say that my mother is not good, she is not able to protect her sister, and she has to add trouble to her, her sister's hospitalization must be persevered to the end, she must be cured before she can be discharged from the hospital, she can't give up halfway, that little beast can't pester her sister anymore in the future, so this time as long as the mental problem is cured, you can live a good life in the future." ”

"You can go back and say these words to your daughter in person, so that you don't see them once." Although with the evidence they have, coupled with Wei Huili's current reaction, her murder suspicion is basically certain, but Du Juan still feels a little unbearable when she hears what she says.

I thought that Wei Huili would get a little comfort when she heard this, but she just shook her head: "I don't want to see them, I don't want to see either of them." I'm not a qualified mother, and I can't provide a particularly good living environment for my daughter since I was a child, that's all, I haven't even done a good job in education, and my younger daughter has become like this, and my eldest daughter has not spared much energy to care because she is patronizing and taking care of her sister, so I am not a good mother to either of them, and now I have become a murderer, and I have no face to see them. I can feel a little better without them, and if I see them, I guess I will want to die directly. ”

Since Wei Huili is so insistent, of course Du Juan and Tang Hongye will not say anything, as the so-called Qing officials are difficult to decide family affairs, Wei Huili wants to meet her daughter again before the last moment, this is her personal choice, no one else has the right to interfere, as for whether her two daughters will insist on wanting to see her at that time, it is also a matter of coordination at that time, and it is not within the jurisdiction of Du Juan and Tang Hongye.
