The three of them returned to the Bahe District Criminal Police Brigade. Wang Dong and the forensic doctors from Bahe District were conducting autopsies on the real cause of death of the two deceased people. Xu Zheng thought about it and finally did not go in. He did not have a forensic certificate and said that he was professional. Just like bragging, it is not convincing enough.
When he came back, he didn't have nothing to do. He temporarily set up a special team. In addition to Xu Zheng, Zhuang Qiang and Xiang Ruonan, Yan Zhengyang also added three criminal police officers to the special team, so there were six people.
There is also the leader of the special team. Originally, Yan Zhengyang was interested in Xu Zheng, but Xu Zheng’s qualifications were still relatively young, and he was still a guide sent by his superiors. In addition, he had too much work at this stage, so he finally asked Instructor Wang from the Criminal Police Brigade. Become the leader of this group.
Instructor Wang is not very busy at work, but everyone knows that he is not in charge of business. Xu Zhenglai is mainly in charge of this group.
Xu Zheng did not show any timidity at this time. Yan Zhengyang was able to appoint him as the deputy team leader. This was the trust of the Bahe District Criminal Police Brigade in him. He guessed that Wan Haihong had this consideration in asking him to come down to provide guidance. Perhaps, the truth of the matter is that Xu Zheng came down to take charge of the investigation of this case, and this case was given to the Bahe District Criminal Police Brigade as an indicator.
It was all an exchange of interests, but for Xu Zheng, it not only gave him training and increased his resume, but also gained the favor of the Bahe District Bureau. He had to sigh that the Wan detachment was really scheming.
After Xu Zheng hurried back, he went to Instructor Wang's office and chatted for a while, and then their special team held a short meeting.
What surprised him but also made him feel that it was reasonable was that the remaining three male colleagues in the special team did not have any objections to him as the deputy team leader and the person in charge.
Maybe the three of them were thinking that this time they were just studying with the prince, but Xu Zheng still hoped that everyone would do their best for the sake of the prince, "I just went to Zhaoyang Hotel, and to be honest, I found some doubts, but now The forensic doctor has not concluded yet. They will check today and the results will be available tomorrow at the earliest.
But I don’t want to wait for the forensic doctor’s conclusion, so I hope we can go ahead of the forensic doctor and conduct the investigation based on murder. "
Xu Zheng himself has advanced forensic technology, and he is also well aware of the time it takes for forensic test results to come out, and the error rate. Therefore, a diagnosis must not rely solely on those high technologies, but more depends on the evidence.
Where does the evidence come from? It's not just them, the criminal police, who investigate and make notes for you...
An old policeman surnamed Li from the special team did not hesitate, "I also think this case is suspicious, especially when two people had sex at the same time. To be honest, I have never seen such a weird way of death in my more than ten years as a police officer." .So, I support Team Leader Xu’s conclusion.”
The remaining two young detectives also nodded at the same time, "Then Team Leader Xu will arrange the tasks. We will listen to the leader."
Xu Zheng was secretly happy to see them being so cooperative. It saved him the effort of wrangling, and there was no need to make things difficult for a new official to take office. He turned to look at Instructor Wang, who nodded with a smile, "That's okay. Let’s just listen to Xiao Xu’s arrangements and try to detect this case as soon as possible.”
Xu Zheng was no longer polite, "Let's just dig deeper according to the previous investigation direction and divide into four groups. One group will investigate all the activities and contacts of the two deceased people in the past week, especially those with doubts. The phone number needs to be marked, and whether the two deceased people have provoked anyone outside.
The second team is going to investigate all the room opening records of the deceased this year, including their room opening records with other women or men. By the way, you can also check whether the two partners of the deceased had an affair.
For the third group, just ask yourself. Go to the reproductive department of the hospital and ask if there are any drugs that can make people become pregnant at the same time without being discovered. If there is no news from the hospital, go to the provincial department and find out. Professor Ji Dongliji, ask him.
The fourth group, Brother Li, and Xiang Ruonan, went to check the staff of Zhaoyang Hotel. The focus was on the cleaning and logistics of room 6002, as well as the staff in charge of the monitoring room.
The key point is to investigate who had been to this room yesterday morning and the day before yesterday. Also, ask them if there are any private goods in the hotel. They will understand. "
Xu Zheng himself had no intention of going out to look for clues, because when he went to the hotel, he copied the three-month surveillance video of Zhaoyang Hotel. This is why hotels usually save three months of video before letting him try to find it. A little clue.
After arranging the tasks, everyone performed their duties. Strictly speaking, it was not difficult for such a case, it was nothing more than money, hatred, and love. Otherwise, who would have spent so much effort to kill such two people.
After the others went out, Xu Zheng said to Instructor Wang: "Instructor Wang, please contact the police station in the jurisdiction of the two deceased people and ask them to help copy all the surveillance videos of the community where the deceased lived in the past half month. "
"No problem, I'll call them right now. Do you want to go to the visual reconnaissance brigade to retrieve the surveillance video of the two deceased people from the community to the hotel yesterday?"
Xu Zheng thought, this is okay, "Professor Wang thought it through. If you didn't tell me, I would have forgotten."
"You don't need to put a high hat on me. But, Xiao Xu, you have to adjust so many videos, do you want me to find a few people to help you share the load?"
Xu Zheng shook his head, "No need. I can almost finish watching these videos in an afternoon. Teacher Wang has something to do and hurry up. I'll call you if you need anything else."
After sending Instructor Wang out of the interrogation room, Xu Zhengcai took the USB flash drive to the Visual Reconnaissance Brigade of the Bahe District Bureau. He still had to borrow their equipment. With just a few ordinary computers, he would really not be able to finish all the videos. .
There are more than a dozen cameras in Zhaoyang Hotel, among which Xu Zheng copied the videos of three cameras, one is the entrance, one is the cashier, and the other is the corridor on the sixth floor.
Comparing their room opening records, Feng Yapeng and Su Yin opened a room a total of 7 times during these three months. The sixth and seventh times were separated by a month, and the seventh time was the time when they died.
Xu Zhengxian played these three videos at the same time. Their check-in time was 7:25 yesterday morning, so Xu Zheng set the recording time at 7:00 in the morning.
In the video, Su Yin drove her Audi A4 to the Zhaoyang Hotel parking lot at 7:12, waited in the car until 7:20, got off the car and went directly to the front desk to use her ID card to open a room.
The check-in time was 7:25 in the morning. Feng Yapeng arrived in his Mercedes shortly after, then went directly to the sixth floor and entered the room, looking very anxious.
Because the current cameras have very high pixels, you can basically see the pockmarks on their faces. Therefore, Xu Zheng selected the frontal photos of the two people. After looking at them for a long time, there was nothing unhealthy, the only thing that was a little abnormal. It's the eyes.
Xu Zheng understood this kind of look. During this time, he and Han Xin looked at each other like this at night.
After watching it twice, especially the video from the camera at the door, no suspicious person was found following Feng Yapeng and the others. Xu Zheng fell into deep thought. If there is a drug, such as a drug that helps with exercise, according to Feng Yapeng and the others' previous date time And the number of times this drug should not be used.
It's a medicine that's three parts poisonous, not to mention such a powerful medicine. If someone else didn't bring it here, it must have been Feng Yapeng and the others. But, could it be that they used this medicine?
Or maybe they don’t know how powerful the medicine is?
Xu Zheng always felt that it was impossible. He picked up his mobile phone and called the old policeman Brother Li, "Hey Brother Li, I am Xu Zheng. You are doing investigation in the hotel, right? I have a question, please ask it for me. Ask the cleaning lady if she remembers Feng Yapeng."
Old policeman Brother Li was questioning the cleaning aunt. After hearing this, he directly suggested to Xu Zheng, "Team leader Xu, I turned on the speakerphone. If you have any questions, you can ask directly. The cleaning aunt remembers Feng Yapeng and Su Yin. They are often A regular customer of this hotel.”
Xu Zheng calmed down and said, "Hello, Auntie, I would like to ask, are you the one who cleans up the house every time Feng Yapeng and others move out?"
"Yes, I am in charge of the hourly room on the sixth floor. They are also frequent guests. I remember them. The girl is so attractive. I didn't expect..."
Xu Zheng rubbed his nose. This aunt is quite chatty, "Auntie, let me ask you a question. This question is very helpful to our police. Have you ever heard of their wall root before?"
The aunt on the other end of the phone was from the Northeast who came to work in Changming. She wanted to get angry when she heard this, but she suppressed her anger when she thought that the other side was also a criminal policeman. At the critical moment, Xiang Ruonan quickly persuaded: "Auntie, we are dealing with something. , if we break the eucalyptus earlier, your suspicion will be gone, the hotel can open for business earlier, and you can continue your work, right?
How difficult it is to find a job these days!
Besides, if our police cannot crack the case, you and your colleagues will be the subjects of our suspicion. "
Xu Zheng did not expect that Xiang Ruonan was very eloquent, both soft and hard. In fact, the cleaning lady had never seen anything happen, but she just felt that Xu Zheng was a bit uncomfortable asking her this question in front of so many people.
However, she thought about it and realized that this was also the job of the police. "To be honest, I did hear it a few times. Let me tell you, that woman's voice is really loud. She clearly looks like Lin Daiyu, but in the end she sounds louder than Hai Tianyi." It’s still big.”
"Um, auntie, who is this Hai Tianyi?" Xu Zheng asked curiously.
The cleaning lady was dumbfounded and glanced at the old policeman Brother Li, "This?"
Brother Li raised his hand, "Xiao Xu, let's ask something serious!"
"Auntie, according to what you heard, do you think the dead man was Feng Yapeng? Did you see the packaging bags of his medicine when you were cleaning?"
"No, I've been working here for five years. It's been more than two years since I noticed them. I haven't found that the man used any medicine, and the woman didn't take birth control pills. Anyway, I didn't find any of this garbage after they left."
Old policeman Brother Li asked the cleaning aunt again, "Auntie, based on the results of your observations here for so many years, Feng... is that man. Do you think he will use those drugs?"
Unexpectedly, the corner of the cleaning lady's mouth twitched, "That man walked steadily and his face was red. But Officer Li, I think you should use those medicines, but those medicines have side effects. I have an old prescription here. You How about giving it a try?”
The call was not hung up, Xu Zheng naturally heard it and almost laughed out loud. Old policeman Li Ge rolled his eyes speechlessly, not wanting to say anything, and asked Xiang Ruonan, who was holding back his laughter, to take the cleaning lady out quickly.
Xu Zheng smiled and felt sad. Ten detectives out of ten had kidney deficiency. The main reason was not getting enough rest or sitting for long periods of time...could he be like this in the future?
After hanging up the phone, old policeman Brother Li touched his waist. He felt a little regretful that he didn't ask the cleaning lady for the prescription because he was too concerned about face. After a while, Xiang Ruo, the male god, came back mysteriously and handed him a piece of paper. , "Brother Li, why don't you try this recipe first?"
Xu Zheng didn't dare to sit anymore. He stood up and walked around, practicing the six-character mantra breathing method. From the words of the cleaning aunt, he judged that Feng Yapeng and Su Yin would not use drugs to cheer them up, so this drug must have been prepared for them by someone else.
But how can this medicine work?
And what kind of medicine is this?
It was a pity that the toxicology given to him by the system could not be analyzed when he was not exposed to drugs, but he suddenly remembered the elk scent mixed with the smell of rust that he smelled on the hotel sofa.
Elk incense has the effects of rejuvenating the mind, activating blood circulation and promoting menstruation, reducing swelling and relieving pain. It has no effect of stimulating happiness. Xu Zheng thought again, no, it also has another effect, that is, it has a strange fragrance. Melting it with alcohol can make the fragrance It lasts for a long time and the fragrance is very fragrant.
It is indeed possible if someone uses this fragrance to disguise the true taste of the medicine he is using. Besides, he only knows a little about this stuff. What if this is also an ingredient in medicine?
At present, it seems that this thing is still on the clothes of the two deceased people. The inspection department is currently collecting evidence. Xu Zheng feels that there is no rush and lets them work first.
He continued to look through the videos and found the sixth one. This time, Feng Yapeng came early and waited for Su Yin after checking in. After finishing, the two of them left one after another...
Xu Zheng checked the time and watched all the videos of the two dating, and finally found a suspicious person in the video of their second date. This person was none other than Li Yiming, the husband of the deceased Su Yin.
Although the distance was a bit far, for Xu Zheng, it was enough to recognize that this person was Li Yiming, even if he was wearing a hat and mask.
