Solving the case: Combining the police dog's olfactory genes at the beginning

Chapter 109 Case Investigation (Please subscribe, collect, and vote monthly)

For criminal police, the most troublesome cases are those where the murderer kills someone randomly.

If an acquaintance commits the crime, or if the killing is premeditated, no matter how secretive the murderer is, some clues can be found as long as the interpersonal relationships of the deceased are investigated.

I'm afraid that the murderer didn't know the deceased at all before, but he suddenly decided to kill after seeing the deceased. There will be no clues in the investigation of this kind of case, which will undoubtedly increase the difficulty of detection.

Therefore, after Zhang Fan analyzed it, everyone felt a little heavy. Only Wang Lei said disapprovingly, "I think this is definitely not a random crime. If it was a random crime, why did he take away the deceased's clothes and belongings? He just didn't want to let anyone do this. People know the identity of the deceased, so I think the murderer must have known the deceased.”

"That's true. Why be so cautious if you don't know the murderer."

"As long as an acquaintance commits the crime, it will be easy to handle. As long as we can find out the identity of the deceased, we will definitely be able to follow the clues and find the murderer!"

Xia Zheng and Zhong Jun immediately agreed with Wang Lei's point of view.

At this time, Luo Fei, who had been silent, opened his mouth and poured a basin of cold water on the three of them.

"Don't be too happy. Taking away the deceased's clothes does not prove that the deceased and the murderer knew each other. After all, many murderers have some quirks."

Out of conviction of his ability to solve crimes, everyone looked at him. Zhao Donglai asked in a deep voice, "Luo Fei, tell me what you think."

Although Yang Su and Zhang Fan's analyzes just now were very reasonable, what he wanted to hear most was Luo Fei's opinion.

After all, ever since Luo Fei entered the police force, he has not missed any case that he analyzed and reasoned about.

"Captain Zhao, although I can't tell yet whether the murderer and the deceased knew each other, the murderer took away the deceased's clothes because he was definitely not afraid of people recognizing the deceased's identity."

“How come you see?”

"Have you forgotten Wang Fu's case? In order to prevent others from finding out Wang Fu's identity, Zhang Meng smashed Wang Fu's face to pieces. This is the correct way to bury the identity, rather than simply smashing the deceased's face. Just take the clothes away.”

"That being said, it really makes sense. After all, what's the use of just taking away a few clothes? As long as a missing person notice is issued, the identity of the deceased can always be found."

"Yes, it seems that it was Team Leader Luo who analyzed it. The murderer only took the clothes of the deceased because of some strange habits."

"But if that's the case, I'm afraid this case will be difficult to handle, and it might become an unjust case again."

Every year, the police receive many cases of killings caused by passion. No matter what type of crime they are, they all have a common feature, that is, the murderer and the deceased had never known each other before, and the murderer committed a murder of passion.

The probability of solving such cases is less than one in ten, which means that nine out of ten cases have become unsolved cases and are included in the police archives.

Perhaps one day the murderer commits another crime and the police happens to discover it, then the victim can be vindicated, but in most cases it will always remain an unsolved case.

Thinking of this possibility, everyone couldn't help but feel a little depressed for a while.

As police officers, they certainly hope to bring criminals to justice.

Feeling their frustration, Luo Fei quickly said, "You don't have to be so pessimistic. We haven't investigated anything yet, so it would be too arbitrary to conclude that it is an unjust case. What if there will be a turn for the better?"

"Yes, Luo Fei is right! We are the people's police. It is our duty to arrest the real culprits and give justice to the victims. If we shrink back after encountering a slight setback, then we are still policemen. Go home early and sell sweet potatoes. Bar!"

Zhao Donglai scolded everyone with a dark face.

Everyone seemed to have been given a slap in the face, and they all looked ashamed and did not dare to speak.

Zhao Donglai didn't count on them anymore and looked directly at Luo Fei, "Luo Fei, please tell me your thoughts."

"I think our first task now is to determine the identity of the deceased and then launch an investigation. In addition to investigating the deceased's interpersonal relationships, there is also his recent movement trajectory."

"Regardless of whether the deceased and the murderer knew each other, their movement trajectories must have overlapped. In addition, the deceased was not from Yangjiacun, but the body appeared in Yangjiacun, which shows that the murderer should be relatively familiar with Yangjiacun."

"So we can also visit Yangjia Village and several nearby villages, focusing on those who are single or have weird personalities. After all, judging from the murderer's criminal methods, the other party is likely to be a gay man, and such people Their personalities and behaviors are somewhat different from ordinary people, so they must be easy to distinguish.”

Zhao Donglai nodded frequently after hearing this, "Okay, then you will set off immediately and go to the village to visit and investigate the situation."

"Yang Mei, please repair the photo of the deceased immediately, and then compare it with the database of the public security system to confirm the identity of the deceased as soon as possible. Also remember to send another photo to several surrounding towns and ask them to work together to identify it. "

"Also, we will test the liquid extracted from the deceased's body, extract DNA, and compare it with the database, in case the other party has a criminal record."

Although the chance of this is very slim...

"Good team Zhao!"

After some arrangements were made, everyone immediately prepared to go and work separately.

Here, Luo Fei, Yang Su and Zhang Fan walked out of the conference room. Yang Su immediately said, "Yangjiazhai is close to Xujiazhai and Kanshui Village, so our group will be responsible for Kanshui Village."

"Then our second team will be responsible for Xujiazhai."

"Okay, then let's go to Yangjiacun."

After a brief discussion between the three of them, Luo Fei took the members of the three groups straight to Yangjiacun.

At [-]:[-], their car stopped at the village committee of Yangjia Village.

The village chief Yang Tianfu warmly entertained them, "Comrades have worked hard, come in and have a cup of tea."

"No need, village chief. We are here mainly to find out some information from you."

"Comrade, you can ask whatever you want, and I will definitely cooperate with you in your work."

The village chief is quite enlightened.

Luo Fei thought to himself, and then began to ask, "Village chief, are you sure the male corpse by the ditch today is not from your village?"

"That's definitely not the case. I am not bragging to you, comrade police. I have been our village chief for more than ten years. Let alone a human being, even if I beat a dog passing by the roadside, I would know if it belongs to our village! Today That person is definitely not from our village."

"Could he be from a neighboring village? Or think about it carefully, have you seen this person before?"

Yang Tianfu thought about it seriously, and then shook his head, "I really don't know if he is from a neighboring village, but I'm sure I haven't seen him. I'm not bragging. Don't look at my age, but I have a good memory. I remember exactly who the family members were, including the color of his dog!"

Luo Fei felt very speechless as he watched Yang Tianfu patting his chest and repeating his assurances, almost swearing to the sky.

The village chief is enlightened, but he is too talkative and full of nonsense.

Wang Yong simply snorted, "Village Chief, then your memory is indeed very good."

Not hearing that he was joking, Yang Tianfu said enthusiastically, "Of course, I'm not bragging..."

"By the way, village chief, can you ask if there are any men in our village who are single and unmarried, or who have quarreled or divorced due to discord between husband and wife? Regardless of age, as long as they meet these conditions, they will be considered." I'm afraid he will talk in a long way again. After making a lot of nonsense, Luo Fei spoke in time and finally interrupted his spell casting.

On the way here, Luo Fei had already analyzed that although the other party was gay, it did not mean that he had never been married.

After all, in conservative-minded villages, it is a great shame for a man not to get married, so the other party is likely to get married under pressure from public opinion and family. But if he has such a habit, the relationship between the couple will definitely not be so harmonious.

Regarding this, he also called Zhang Fan and Yang Su and told them to pay more attention.

"Comrade, if you ask this, that's a lot. After all, there are many young people in our village who can't find wives."

Luo Fei hurriedly added, "Those who work outside do not count, as long as they are in the village during the recent period."

"Then there are only a few left."

"Please tell us."

As he spoke, Luo Fei glanced at Wang Yong and motioned for him to write it down quickly.

After the village chief finished speaking, Luo Fei asked again, "What about couples who are at odds with each other, quarrel frequently, or are divorced?"

"This is quite rare. We are in a new society now. Except for that bastard Yang Dawei who beat away his wives, the men in our village all know how to love women. There are very few quarrels, let alone divorces."

"Oh, by the way, it seems that the son of Yang Erwa's family in the village is divorced, but that child has been working out of town recently, does it count?"

"This doesn't count. We only need people who have been in the village recently."

"Then there's only Yang Dawei." The village chief said with a strange look, "But comrades, why are you asking about this? Do you suspect that they killed the body? Then you must be mistaken, they are absolutely It’s all innocent!”

Although he knew not to reveal any details of the case, Luo Fei couldn't help but ask, "Why is the village chief so sure that they are all innocent?"

After asking, he regretted it and secretly wondered if the village chief would pat his chest again and say, "I'm not bragging..."

Fortunately, he overthought it. Liu Tianfu did not repeat his classic lines, but said seriously, "Because there is nothing wrong with their health."

Luo Fei didn't quite follow his train of thought for a moment and was still in a daze, but Yang Tianfu approached them with a mysterious look on his face, "I've heard about the Jiulihe case before. The murderer wanted to cut someone else's place because something was not working. Treat diseases, but they are not incompetent, there is certainly no reason to do such a thing, comrade, what do you mean to me?"

They are all from the same county, and the Jiulihe case naturally spread in the surrounding areas. Therefore, after the same crime occurs this time, everyone will inevitably think that the murderer's purpose of killing is the same as Ma Kai.

"Village Chief, you are not allowed to speculate before the case is made public. Moreover, you are still a public official, so you need to pay special attention to your words and deeds. Otherwise, it may cause unnecessary panic. Do you understand?"

Luo Fei said seriously with a straight face.

Although Yang Tianfu was full of gossip, he quickly calmed down when he heard this, "The police comrade is right to criticize, I will definitely pay attention to it."

"Well, village chief, thank you for your cooperation. We have to rush to other villagers' homes to understand the situation, so we will leave first. Also, if you think of any missing details later, you can contact us by phone."

"Are you leaving now? Why don't you sit here for a while and I'll ask my mother-in-law to prepare some food..."

"Thank you village chief for your kindness, but it's really no need. Let's go."

"It's just a meal..."

"It's really unnecessary..."

After finally rejecting the hospitable Liu Tianfu, the two of them walked out of the village committee almost as if they were running away.

Wang Yong patted his chest and said, "Team leader, this village chief is so hospitable. I almost couldn't resist him just now."

"It's indeed a bit... Okay, let's hurry up and join Zhang Fan and the others to see if they have gained anything."

"it is good."

As soon as they arrived at Yangjia Village, the five of them split into two groups. Luo Fei took Wang Yong to find the village chief to learn about the situation.

Sun Jun and the three of them went to the nearby villagers and made simple inquiries to prevent the village chief from omitting anything.

Soon the five people met at the head of the village.

"How about it? What did you all find out?"

"Team leader, we just asked some fellow villagers and this is the list they said meets those conditions." Sun Jun said, and handed the notes in his hand to Luo Fei.

Luo Fei took a casual glance and found that they were all the people the village chief mentioned before.

Wang Yong came over to take a look, and couldn't help but exclaimed, "It's not bad at all. It seems that the village chief is really not bragging. He really knows everything about the village. What kind of skill is this!" "

"Don't be surprised. For an old village chief with such qualifications, remembering the people of a village is just a piece of cake."

Luo Fei said casually, and then started to make arrangements.

"Sun Jun, Zhang Fan, and Zhao Cheng, you three are still working together as a team. Let's go visit these people's homes. Wang Yong and I will go to these homes."

After quickly dividing the names of the people recorded in the book, Luo Fei said seriously, "Remember, you must be more careful and observe carefully, you know?"

"Okay, team leader, don't worry."

Sun Jun said, and sure enough, he led Zhao Cheng and the two to work quickly.

Luo Fei took Wang Yong towards Yang Dawei's house. They had just asked the village chief for his location, so the two of them found it easily.

Yang Dawei's home is a low and dilapidated cement house. It is indeed somewhat unique in Yangjia Village, where the average per capita is a small Western-style building.

Looking at the garbage on the ground in front of the door, and thinking of the village chief saying that Yang Dawei was lazy, Luo Fei felt that this was true.

He stepped forward and knocked on the crumbling door. After a while, an impatient voice came from the room.

"Who is knocking?"

The tone is ferocious, which makes people a little unhappy when they hear it.

"Is Yang Dawei at home? We are from the Public Security Bureau and want to find out more about the situation from him." Luo Fei said, and there was silence.

He was not in a hurry, so he waited patiently. Not long after, the door was opened, and a man with a sinister face appeared in front of Luo Fei.

Luo Fei's originally leisurely expression suddenly became stern!
