Chapter 1154 Clue
Cai Xiaonian's family really invested a lot of money, and with the help of Wang Yan, they did not ask people in the courtyard to get furniture as in the original drama. This family took a cabinet, and that family took a stool, which also showed the human touch in the courtyard.

This time Wang Yan was helping, so new furniture would definitely be better, not to mention the craftsmanship and price were guaranteed. So the Cai family began to borrow money from relatives and friends. One borrowed fifty, another borrowed one hundred, and together they had more than one thousand.

This is not a small amount of money. The normal salary of workers these days is only 40 or 50 yuan. Even Wang Yan himself, who has made so many contributions, only makes more than 70 yuan a month. But this salary is already very high. Old Ma, with his contributions, seniority, and the position of team leader, is equivalent to him.

Cai Xiaonian's family conditions are certainly good. Old Cai has been driving a train for many years. With his professional title, excellent evaluation, and seniority, he can earn 70 or 80 yuan a month. Cai Xiaonian's salary is less, about 50 yuan. Cai's mother is a stay-at-home woman who does some handicrafts to earn money.

A family can earn more than 1,000 yuan a year. But after deducting living expenses, the amount of money that can be saved is relatively small. This 1,000 yuan will take a family three to five years to pay off.

This is normal. Even though Cai Xiaonian's family has a high income nowadays, they are not rich after all. They are still an ordinary family. For such families, marriage basically means famine. It is not much different from decades later.

A few days later, when Cai Xiaonian came back, Wang Yan took him to the furniture factory and spent 850 yuan. Wang Yan paid for a wardrobe as a gift, which was a good deal.

Wang Yan is of course a man of particular tastes. When they meet, Cai Xiaonian greets him as a close brother, and he is not stingy with his words.

After all, he really had money. In fact, even if he paid for everything, he would have enough money. It was just that he couldn't take it out. Cai Xiaonian was not his son. Borrowing two hundred yuan and giving a wardrobe was the limit.

This matter has come to an end for the time being, and we will just have to wait until next spring to get married...

Wang Yan's life was still as normal as before. He provided footprint identification to various units that came to him, occasionally participated in collective actions, occasionally got in the car for a ride to catch thieves, human traffickers, etc., and of course he would also find cases to work on.

Wang Xin took a file and placed it on the desk: "How about taking a look at this case?"

Ma Kui read it first, and then gave it to Wang Yan to look at. At this time, Wang Xin said, "Two years ago in the winter, on the Ningyang to Yinzhou section, a patrol worker found a crushed body. According to forensic identification, the deceased was a female, aged 20 to 25, with signs of rape. There were strangulation marks on the neck, suspected of suffocation. In addition, there were multiple injuries on the body, suspected to be caused by the murderer's beating.

We checked the surrounding area, but couldn't find any missing persons. We finally determined it was a case of rape, murder and corpse abandonment, and after many investigations, we put the case on hold without any results. Oh, yes, you saw this footprint once before."

Wang Yan looked at the newly added white paper in the file. On it was his handwriting, and even his signature. Within Liao Province, his signature was evidence of footprints. It was because none of the footprint identifications he had done in the past were wrong, and he had solved hundreds of cases across the province. The other unsolved cases were not because his footprint identification was wrong, but because there were not enough clues, and he couldn't even identify the suspects...

"Height 175cm, weight 120kg, age around 223." He looked at the footprints in the photo, confirmed them again, and said, "Do you have any ideas?"

Ma Kui also looked at Wang Xin.

The latter shook his head honestly: "No, I was thinking that the one we did before was also dismemberment, can we try it again this time. Judging from the information we know so far, it was not thrown from the train, but moved from somewhere else. The murderer is not from Ningyang, and he is not far away, definitely within this range. This deceased is most likely the same. The person is in Ningyang, and a murder was committed, it is impossible that there is no trace at all."

Ma Kui shook his head: "There are two things to solve a case. One is to identify the deceased, and the other is to identify the murderer. This is not like the previous case of Liang Lihong, where we had clues to find her identity and identify the murderer. In this case, the only clue is a footprint. We don't know anything else, so how can we find it?"

"Is it the same thing we said last time? Let's look it up. We may find some clues." Wang Xin was very optimistic.

"There's nothing wrong with what you said." Wang Yan nodded with a smile. He had not seen this case before. The last time he saw it was the footprints.

But now that I have seen it, it is actually nothing. This kind of biological information was cleared up as soon as possible after the application of DNA extraction, detection and comparison technology in China.

But on the other hand, it feels wrong to wait so many years to solve the case and let the murderer go unpunished. And there is a difference between having killed someone and not having killed someone. If you dare to kill someone for the first time, you will dare to kill someone for the second time, which is also a hidden danger.

But the police are human, not gods, so they can only put it aside, take a look at it when they have nothing to do, or look forward to technological innovation...

"Look, this is what my brother said before." Wang Xin nodded happily, "Actually, I have an idea, but I don't know if it will work."

Ma Kui was annoyed: "Then tell me."

Wang Xin chuckled and said, "The deceased was not very old, and her clothes didn't look too bad, so her family must be well off. If such a person goes missing, the family will definitely report it to the police, and the various units will definitely file a case after receiving the report. Let's pull out the missing persons list from Ningyang and nearby areas, and make a separate list of women of similar age, and there is a high probability that we can confirm the identity of the deceased.

As long as the identity of the deceased is confirmed, we can proceed with the investigation."

Ma Kui smiled and said, "Then why didn't the comrades who were in charge of the case do anything?"

"It's different, Lao Ma. When we were collecting the names of people, we had to go to each place one by one. Now the names must have been compiled. Let's not worry about other things. Let's collect the people from Ningyang first. We just need to go to the Municipal Bureau. If we include the people who went missing that winter, how many people can there be? It's true that many people disappeared, but there can't be tens of thousands of people that winter, right? We can definitely make it.

If Ning Yang doesn't have it, forget it, we can't afford it. I guess they didn't do it before because of the same idea. There are too many cases to handle. Fortunately, my brother is in our team, and he's quick to produce results. In addition to helping out, we can also look back at previous cases."

"Don't tell me, now I'm really using my brain."

Wang Yan also nodded with a smile: "Okay, then you go and check the list. I'll go check the body later and try to get the age of the deceased more accurately."

Wang Xin's eyes widened: "You can do this too?"

"I was taught that in school. I also read some books and learned a little bit. I'm a genius. Don't fight yourself."

"Go quickly, you're second in the police academy!" Old Ma sneered with a smile.

Wang Xin let out a long sigh and shook his head helplessly: "Since we have Yu, why do we have Liang..."

Although he was used to being hit, he still felt bad every time he was hit in the face. He left immediately and ran to the city bureau to retrieve information...

Old Ma asked curiously, "Can it really be determined accurately?"

"Look, we are still a family, and you don't believe me?"

"What level?"

"Maybe it's a little worse than my footprint identification? After all, it's all theory. I've only seen a few corpses. Only through practice can one gain true knowledge." Wang Yan said modestly.

"Let's go, I'll go do some paperwork, and we'll go to the funeral home."

The murder case is not solved and the identity is unknown. These days, after the forensic doctor issues a report, confirms the cause of death, and extracts various information, the body is sent to the crematorium for cremation and then kept in the funeral home. After the identity of the deceased is confirmed, it will be returned to the family. This was the case with Liang Lihong. She had already been cremated and only some bones were left.

The situation is the same now. The body from two years ago cannot be preserved. There is no condition at this time, so it can only be burned. However, Wang Yan only looks at the bones.

In the funeral home, under the watchful eyes of the funeral home staff and Ma Kui, Wang Yan put on gloves and turned the bones back and forth, pretending for a while, and finally made a judgment.

"The previous forensic doctor's judgment was correct. There is no problem with the age of 21 to 25. Let me be more precise. It's between 22 and 23. We'll check based on these two ages later, taking into account both the lunar and solar calendars." "Are you sure?" Lao Ma looked skeptical.

"Who can be sure? Check those of this age first, and if that doesn't work, expand it. There aren't that many people anyway, so we're just going to make a precise attack first. It's good to avoid unnecessary mistakes."

So the two of them went to the Municipal Bureau to meet up with Wang Xin, and the trio began to search for missing persons who met the criteria one by one.

First of all, the time limit was set, which was between seven days before the crime and half a month after the crime. After all, it was inevitable that the time limit would be relaxed because of something that happened to the deceased. The second was the gender, which had to be female. The third was the age chosen by Wang Yan.

In the end, only three candidates were identified.

The trio didn't say much. Each person was responsible for one task and then they went out to visit.

In the afternoon, Wang Yan and Ma Kui went back to the bureau one after another. Wang Xin did not come back until near evening.

"I found it." As soon as he came back, Wang Xin drank up all the hot water that Wang Yan had left.

He opened the notebook and said, "Her name is Feng Xiaoling, she's 23 years old. On the afternoon of November 15 two years ago, she went to the movies with her friends and disappeared. In the late night of the 16th, a patrolman found her body. Everything matches up. Here's a photo. Take a look. She doesn't look bad."

After handing over the photo, he continued, "I also asked for the name and address of that friend, but I haven't been there yet. I'm not very experienced and I'm afraid it will delay things."

"Oh, I really overestimated you." Ma Kui smiled.

"Then you see, I know myself well. This friend is Zhang Yinglan, and together with Feng Xiaoling, they are both employees of the canning factory. The two of them also met after work, and they usually walk close to each other and often go out to play together during breaks.

In addition, Feng Xiaoling was also engaged at the time, and they were going to get married in the spring of the following year. The man was Zhao Youmin, who worked in the district government. She had a good relationship with Yu Huaiwen before, but they said they got angry with each other and ended the relationship. Feng Xiaoling's parents said that their daughter was usually very quiet, and she had never offended anyone, let alone had a quarrel with anyone. There was nothing unusual before, but she suddenly disappeared and was killed. That's all for now.

What should we do? Should we go now or wait until tomorrow?"

"Definitely tomorrow. The meal is ready at home, so let's go home and eat." Wang Yan said with a smile, "Besides, going there at night may easily lead to misunderstandings. It's better to go during the day."

"That's the truth." Ma Kui nodded.

Wang Xin picked up the cigarette Wang Yan had placed on the table, lit one and smoked it happily. If he hadn't smoked with Wang Yan every day, he would have quit smoking...

"Look, what did I say? Do you have any clues?"

"Don't be proud. Clues are only useful if they can solve the case. If not, then they are useless."

"That's not right, Lao Ma. We have to follow the clues first to see if it will be useful."

"Yes, what you said is useful."

The two of them were talking and laughing, and Wang Yan took the opportunity to look at a few more footprints. Then the three of them went home to eat after get off work...

The next morning, Feng Xiaoling's family came to the police station. Although Wang Yan and Ma Kui gave Wang Xin a high degree of trust, they showed them the photos and the bloody clothes. They confirmed that it was the clothes Feng Xiaoling wore that day. They also made some inquiries, but there was basically no discrepancy and no further gains. Then they arranged for someone to take them to the funeral home to collect the body.

The trio acted together and questioned people who had contact with Feng Xiaoling.

When there is a murder case, if you look for acquaintances first, you can basically solve 90% of the cases. Most of the murders are caused by conflicts between acquaintances, revenge killings, love killings, and profit killings, involving relatives, lovers, friends, and even neighbors.

The remaining 10% is due to various other situations, such as crimes committed by interest groups, criminal gangs, etc., and then there are some temporary desires for money, sex, etc.

So last night, the three of them did not mention any other arrangements. Now that the identity of the deceased has been confirmed, a thorough investigation of the deceased's network of relationships is a must first and foremost.

The three of them visited Feng Xiaoling for many days and investigated her thoroughly. It is no exaggeration to say that her parents did not know her more comprehensively and in more detail than the three of them.

But it is precisely because it is comprehensive and detailed that people feel uncomfortable because they gain nothing.

Wang Xin looked at the handwriting on the notebook and the network of relationships drawn on the newspaper, and collapsed in a chair in dejection: "It's over, a dead end. Old Ma, you're right, the clues are useless. But I can't say they are useless, at least the parents have given up hope."

Ma Kui was not affected at all, only Wang Xin felt depressed. After all, he was the one who proposed it, and he had found the family of the deceased first, confirmed the identity of the deceased, and had high hopes for solving the case. But the result was not satisfactory, and the disappointment was even greater.

Ma Kui said, "This is not a normal situation. Don't act like you are dying. If everyone was like you, with so many cases on hold, wouldn't the comrades in charge be crying their eyes out? As a police officer, you must be persistent and never lose heart."

"I just said that, and it's been almost half a month. I checked everything that should and shouldn't be checked, but it didn't help at all. I'm really upset."

"What is useful and what is useless? You have to wait and see."

"No, that's not what you said last time. Well, I've let you say both the pros and cons."

Wang Yan shook his head with amusement and said, "If this road doesn't work, then change direction. If it really doesn't work, then wait for technological advancement in the future."

Wang Xin let out a long sigh and said, "From the current perspective, it is most likely a random murder of passion. Feng Xiaoling and Zhang Yinglan were returning home after watching a movie and met the murderer on the way. The murderer saw that Feng Xiaoling was pretty and well-dressed, so he wanted both her money and her body.

We investigated Feng Xiaoling. She was a soft-hearted person with a strong heart. She must have resisted fiercely. The murderer was afraid of being discovered, so he killed her. Then he used some tools to hide Feng Xiaoling's body, took it out of the city, and dumped it on the railway line.

So there are two possibilities: the murderer either lived nearby or was just passing by. Then there are two more possibilities: he had a means of transportation or was just walking by.

Anyway, what we need to do next is to carefully check the route from the cinema to Feng Xiaoling's home."

Wang Yan raised his eyebrows at him: "Look, it's good to use your brain more. You can think more clearly. So, go to Feng Xiaoling's house and ask for two more photos, or ask for two more negatives. Tomorrow we will take the photos and ask along that road."

Wang Xin didn't waste any words. He just responded and left to get the photos.

He had a clear understanding of himself. Wang Yan was the big brother, Ma Kui was the nominal leader, and he was dispensable, a laborer. So, as he had said before, all the errands in the group were his...

I would like to express my daily gratitude to the good brothers who vote monthly, recommend and read quietly for their strong support!
