Guide to Domestic Police Dogs

"Of course, of course I'm not talking nonsense."

Gu Nianyi sorted out his thoughts, glanced at the regretful nurse who was still wiping tears not far away, and said in a low voice, "...The results of the physical evidence appraisal should have been issued, that is, they were at the stove last night. Traces of burning women's underwear were found nearby, and if this can become a more critical piece of evidence, this chain of evidence is established."

"Oh, it seems you already know. So the nurse's side can also testify, and she still kept the swab? Yes, this is indeed critical evidence, it can be contacted, but it still provides us with too little." Li Tai was silent for a few seconds, and then said, "...and Zhang Chang hasn't found anything for the time being. The residential buildings in the neighborhood are being searched urgently with police dogs. Other work is still in progress. Before tonight, all The known evidence has been sorted out, let's go back to the game and check it out."

"Okay." Gu Nianyi replied, "When will the procedure be finished? I need to..."

"Didn't you just say that! Someone has already sent it over!" Li Tai said, "You can't be smarter, do you need me to tell you?"

"..." Gu Nianyi pursed his lips, and could only say, "Understood, thank you, Team Li."

Just as Gu Nianyi hung up the phone, the police officer over there had already recorded a simple statement, and was about to follow the nurse back to his department to pick up the cotton swabs she had left behind for the wipes.

"I've been wondering if I'm a little meddling." The nurse handed the policeman the cotton swab in the bag. "If the little girl is killed because of this, I don't know what to do. I may be a sinner." ..."

"At least you can stand up now, but you lack a little necessary knowledge." Xu Luo looked at her and said, "Have you encountered similar things before?"

"...No." The nurse hung her head, "When I first came to the hospital for more than a month, there was a nurse in the department. She had encountered similar things. At that time, she reported it to the dean, and the matter was over. Yes. I often think a lot, such as whether I am a little nosy... If I wrong the other party’s father, will this also have a psychological burden on the child.”

Xu Luo touched her back. He could see that this nurse had only been in this hospital for a few months or half a year. She was very young and still had an unshakable academic atmosphere.Encountering such a thing can leave evidence, the essence is still clever, maybe lack of experience, or maybe it is the normal state of most people in this world.

There is a long way to go to popularize the law, Xu Luo thought.

"Next time you encounter something like this, please don't hesitate to call the police. This is neither a false report nor a trouble to the police. Instead, we will thank you." Gu Nianyi shook the bag in his hand and handed it to the side The police officer said, "Thank you."

The nurse then seemed to be relieved, and clasped her hands tightly and said, "If you have any information about the child, please give it back to me."

"Definitely." Gu Nianyi said, "Let's go with us first, if you have anything to say, let's go back to the bureau and talk about it."

……

Gu Nianyi briefly told He Tian about this matter on the phone, and asked if He Tian could extract the evidence they needed from such biological samples, He Tian cursed on the other end of the phone: "You are really! Do you want me to repeat this kind of common sense question over and over again! If the cotton swab is extracted and dried well, it is possible to retain DNA, don’t you know?! What are you waiting for, send it to me quickly!”

"...Oh, good." Gu Nianyi hurriedly answered and hung up the phone, and asked the two police officers to bring the doctors, nurses and test materials back to the office. With the basis for investigation, he can call Monitoring, the monitoring of the hospital is very, very important to them. Until now, the technicians are working overtime to cooperate with the artificial intelligence screening, and they have not found the people they need in the monitoring.

"By the way, officer." The nurse said to Gu Nianyi before leaving, "I don't know if this matter is useful, but I still want to explain it to you. The child I saw was very thin and looked younger than children of the same age. Much smaller. With very short hair, it looks like a girl only up close."

"Where's his father, what impression do you have of her father?" Xu Luo asked.

"He looks very gentlemanly and calm, and he talks to us in a very orderly manner." The nurse said, "So... when he says that he doesn't need it or rejects the treatment plan, he will give people a sense of certainty, as if he really understands everything. .”

"Calm and firm." Xu Luo nodded.

"..." Gu Nianyi took a breath, and quickly frowned, "Thank you, what you said is very useful."

……

It was approaching evening.

Gu Nianyi and his team temporarily closed the team and rushed back to the bureau to share and integrate important information. Each team had to inform each other of the current case.

"Fortunately, the former colleague of Chen Hao remembered the plastic bag, so we were able to find the hospital so quickly. What is it called? The details determine success or failure." It was already afternoon when Sun Chengming and Gu Nianyi returned to the bureau. The Bureau held discussions together to integrate the currently available information.

Sun Chengming pulled out the chair and sat with Gu Nianyi, both of them looked a little tired.Xu Luo was originally unable to participate in such an internal meeting, but because of his special status and the need for him to make accurate portraits of several people, he was also arranged to sit with Gu Xinxin. As soon as he sat down, Gu Nianyi was far away Seeing Gu Xinxin chatting with Xu Luo, he laughed from time to time.

In a sense, Xu Luo's seemingly gentle personality is really a very popular existence. In such a place full of rough men's male hormones, Xu Luo's clean and refreshing appearance will make people like him.

However, I didn't think much of it before, this will wait for Xu Luo to show that he is different from others... No, after they have begun to have some further relationships, Gu Nianyi will start to eat as if he has regained his territorial consciousness tasted.

Now is not the time to admire his lover, Gu Nianyi came back to his senses, and displayed the evidence that he had just collected from the team leaders on the big screen.

The air conditioner in the room was still running, Zhang Chang wanted to smoke a cigarette to wake himself up from the overwhelming fatigue, and when Gu Nianyi also started to take out the cigarette case in his pocket, Li Tai saw their intention clearly , coughed at the side, and said: "I said it before, you can't smoke in meetings in the future, there are colleagues here who are not used to the smell of smoke, you old smokers, think about it after all. And there is no one A report shows that what nicotine can activate the mind can only cause lung cancer, I hope that we in the bureau will live a long life."

He took a sip of water from the thermos, and cursed: "Look at the post-[-]s and [-]s in your bureau, each of them is depressed after handling cases for two or three days in a row. In the future, we will encounter major cases that will take more than ten days to solve." What to do! Start by not smoking in meetings!"

"I agree." Gu Xinxin muttered in a low voice.

"I agree too." Xu Luo said with his mouth.

Gu Nianyi saw it all, he rolled his eyelids, and stuffed the cigarette case into his trouser pocket, Xu Luo beside him couldn't help laughing, and cast a glance at him from a distance.

"Okay! Hurry up, Gu Nianyi, let's start." Zhang Chang crossed his arms, "Let me go through all the evidence so far. Time is urgent, so I will make a long story short."

Time is really tight, and Gu Nianyi has no time to prepare for such a meeting. All the documents are displayed in his hands and dictated to everyone: "...the monitoring technical colleagues are still working overtime to investigate, so what can be said There is not much evidence...um...the most important point now is..."

Gu Nianyi supported the table with both hands, his slender figure was wrapped in a blue shirt, and his black hair hung down in front of his eyes.He raised his head slightly, took a breath and said: "...We didn't find anyone, whether it was Chen Hao, Zheng Chenglong, or Chen Hao's daughter, they were all gone, as if they had evaporated from this world."

"We think that Chen Hao has probably been killed." Gu Nianyi pulled out the photo and showed it to everyone, "There was a murder in the bathroom, and you can see that there were large bloodstains on the wall, and he was taken seriously afterwards. Cleaned up, but the way it's being handled with our current technology isn't a problem at all."

Gu Nianyi circled the position: "Since the forensic doctor has not yet found that he can dissect and issue a certificate from the person or the corpse itself, he can only judge from the state of the occult blood found in the room. Straight-line splatter shape, it is judged that the aorta was cut and the murder was committed before the deceased was alive, and the bathroom is likely to be the first scene. This part of the blood has been cleaned up after drying, so even if it is cleaned, there will be traces, it should be the earliest in the house Formed, according to the blood lock time was ten days ago, that is, around the 24th, which is basically consistent with the date of Chen Hao's disappearance provided by Zheng Min. According to the results of the biological trace detection, the blood all came from Chen Hao himself , there were no other traces of the second person at the scene, including saliva, ti, blood or others, and there were not even traces of struggle. Therefore, the surrounding hospitals have not received any cases of severe hemorrhage and shock with cut arteries in recent days, most likely after being murdered It has been dumped."

"In addition, there is a lot of blood in the bathtub, and there are no traces of fighting in the bathtub. Residual human tissue was found in the sewer outlet. These things can be called minced meat. We guess that the corpse was washed away by the water when it was dismembered. In the sewer, because of the greasy characteristics of human tissue, it hangs in the pipe."

"We also investigated the nearby trash cans, asked and visited the surrounding neighbors, and one of the key information I can get so far is..."

"After we went to his house, the neighbor told us that we saw Zheng Min going downstairs with a big package at night. Although he kept emphasizing in the follow-up inquiries that it was his own garbage that needed to be thrown out at night, but We are skeptical about this statement. We are also working hard to find the whereabouts of this bag of garbage." Gu Nianyi said, "Also, people in the community don't see Zheng Chenglong and Chen Hao's daughter Chen Huihui often. I think there are two kinds of things. Possibility... One is that they don't come back often and stay at home. There are only traces of Chen Weiwen's life at home. The other is that the neighbors themselves may not know that it is his child, and we have never seen him. There's not much indication of that either."

"Then...Brother Sun also added to me some things they found yesterday. They found suspected combustion aids and pots for incineration in the room. It is very important information. Someone is trying to destroy something..." Gu Nian Yi let out a long breath, then turned the tablet upside down on the table, and said, "What I'm going to say next is a rough guess about this case based on the current evidence..."

There was no sound in the room, and all eyes were on Gu Nianyi.

"The reason why Chen Hao's daughter is not often seen in the surveillance is... He probably mixed his daughter's clothes with his son's clothes to confuse the people around him. Although he walked in and saw a completely different child, But it makes sense if you don’t show up a few times a month. The nurse who received Chen Haode also gave the same thing, telling us that when they saw the little girl, she was dressed like a boy " Gu Nianyi's eyes were like sharp eagles, and he slowly passed by the people present, and said, "I thought about it, if it is concealed like this, it is indeed feasible, what do you think?"

"It's hard to say why he burned his underwear, but we can actually guess one or two, that is, Chen Hao is very likely to weixie his daughter, and more than once. The Evidence Center will hand over the nurses who did not try to report the case today. Cotton swab evidence for testing." Gu Nianyi paused here, his voice tightened obviously, and he said with some personal feelings, "... If this is a real girl in such a terrible environment, I am very sorry It's hard to imagine what she's been through."

There was silence in the office for a while, and then began to scold one after another.

"Of course, having sex with girls under the age of 14 is not allowed anyway. It is not enough to prove that he is a rape///rapist, and he is probably dead now. What I need to know is , Was it because of this reason that he was killed, and does anyone else know about this girl?" Gu Nianyi picked up the tablet again, "By the way, where is Zheng Min now?"

"There is no evidence for the time being, so I sent it back to school." A police officer said.

"Send someone to follow him and report to us whenever there is a situation. He is not a simple child, and he has not told us the truth." Gu Nianyi said, "As well as his father Zheng Chenglong, once we have his whereabouts, we will report him immediately. Give us."

Li Tai waited for Gu Nianyi to finish speaking, then turned to Xu Luo: "Xu Luo, do you have any ideas here?"

"..." Xu Luo looked at his book, then raised his head and smiled, "There are some."

"Zheng Min is a thoughtful kid who is good at making people follow the direction he wants, so Officer Gu and I feel that he is playing other roles in this incident, and may even be the dominant one," Xu Luo said. , "And Chen Weiwen is indeed young, timid and sensitive. The relationship between him and Zheng Min is not an ordinary neighbor relationship."

"Zheng Min should have been in and out of his home many times. For example, the books he often reads will be placed where Zheng Min often takes. For example, Zheng Min also knows where his favorite toys are. Of course, these habitual things can only be used as Inference." Xu Luo said, "Before, Zheng Min had a very strong desire to transfer away from the police, whether it was the phone number or the bathroom at home, he had been trying to divert the attention of the police, he was very cunning... I don't know Is it wrong to describe a child? If we don’t use special means, we won’t even suspect that there is blood in the bathroom. But when he talks about his father’s anger, it doesn’t seem like a faux pas, he is a very contradictory existence.”

"I'm just offering a way of thinking..." Xu Luo raised his hand and stretched out a finger, "The relationship between Zheng Min and Chen Weiwen will be deeper than what we see, because we can't find the relationship between Zheng Min and Zheng Chenglong now, We can't find the relationship between Zheng Chenglong and Chen Hao, and the only ones in front of us are these two children."

Xu Luo slowly supported his chin with his hands: "My child, it's a very easy disguise. Some reason why you can't see through his heart is that you think he doesn't know, but in fact he knows better than anyone else."

"Do you think the child played a role in this case?" Zhang Chang asked.

"Yes, and it's not a small role. Zheng Min is protecting Chen Weiwen or Zheng Chenglong. As for the purpose, I can't think of it for the time being. Maybe it's because of the girl Chen Huihui, or maybe it's something else...at least when we first After meeting him, he has already started to take action. He is a very courageous kid. After discovering that some of their private affairs may have been exposed because our investigation progressed too fast, he took the lead in telling us about Chen Hao's disappearance. Letting this case get involved, let us turn our attention to the fact that Chen Hao was deceived and went to other provinces and disappeared, but what is his purpose... Maybe it is to help us find Chen Hao or Zheng Chenglong, or to help him find Chen Hao or Zheng Chenglong. Maybe it's to protect someone, to delay time...?" Xu Luo smiled slightly, "But I'm just guessing, please don't mind. You are the ones who handle the case and pay attention to evidence. I believe that at least one special relationship can be found, which can be involved. It's more."

"Very well. Teenagers are now in a period of active thinking. In recent years, the crime rate of teenagers has also shown an upward trend. You really can't underestimate their impact. What's more, this kind of family has some problems. The family is very important to them. There is a big reason for his criminal psychology. Forget it, let’s not talk about this nonsense.” After Zhang Chang listened, he stood up and said: “…Okay, I’m done talking, now, let’s talk about what we are going to do next. "

"It's been ten days, ten days." Zhang Chang patted his hands on the table, "No one can escape with such supernatural powers in modern society. We are the net itself. Now, it's time to close the net!"
