Ms. Sun's home was in trouble, but they weren't even eligible to apply for a search warrant until there was clear evidence.

After all, a long time has passed, and even if the police can determine that the retroactive statute of limitations of less than 20 years is not enough to open a case for investigation, in line with the principle of innocence, even if a body is found in their home, if both of them admit to committing the same murder, and the available evidence cannot determine whether one of them did it, then both of them will be found not guilty according to the presumption of innocence.

As long as Sun Hongyan and Sun Baozhu are smart enough, they can get rid of the punishment of killing. And that's definitely not what people as police officers want to see.

It's a tricky situation, and no one wants to calculate how low the success rate is for the sidelines.

In the end, Wen Mo and the others decided to start from the periphery first, to see if anyone remembered Liu Yumei in Q City, and then secretly inquired about Sun Baozhu's specific situation, the household registration record of the police station shows that Sun Baozhu is 40 years old this year and has never been married, which is still rare in the small city of Q City, after all, this is one of the few cities in China with many boys and girls. What is the reason why he has not been married for many years, combined with the situation of Sun Baozhu's family and Sun Hongyan's extremely hateful attitude when mentioning Liu Yumei, Wen Mo believes that it is likely to have a cordial relationship with Liu Yumei.

In a city of 700,000 people, it is almost impossible to find the footprints of someone twenty years ago, and Cheng Feng found all the places he could find with the help of several local colleagues.

Liu Yumei's years in the welfare home are quite traceable. The child who grew up in a welfare home, even if she has no worries about food and clothing, has a more or less deformed personality, she has become more and more a good girl from the beginning, she likes everything that is expensive and beyond her ability to buy, and she will do whatever it takes to get it.

After graduating from junior high school, she dropped out of school at the age of 16, and her options for earning a living were limited, and she could live a life of spending money like water, where was there any other choice than to sell her body?

Liu Yumei is a chicken, in Q City in the mid-90s, occupations are rare, and it is quite easy to make money, of course, the police are also very strong.

It took them several days to find out Liu Yumei's case record from the old police files with photos, she was arrested many times because of **, but every time she used a pseudonym, which is also the reason why the police in T City sent an investigation notice to their counterparts in Q City at the beginning and failed to find out Liu Yumei's traces.

The last record of Liu Yumei by the Q City police was on November 14, 1995, and four other people were arrested along with her, Qian Aijuan, Li Ming, Wu Xue, and Wang Jing. These names, no matter how you look at them, look like fakes. You must know that the ID card at that time was very easy to copy, and they**women had one** in their hands in case of police raids.

The five people in the criminal record photos are young, flamboyant, unruly, and scantily dressed, and they can still smile indifferently in front of the camera taken by the police, and they are in their twenties, and they are so cynical.

Cheng Attack kept staring at the third person, a girl named Li Ming, in her early twenties, her hair was dyed colorful, her skin was pale like a vampire, and she was pitifully thin, but that face, the more she looked at it, the more it looked like the murderer they had been looking for! Several people repeatedly compared and confirmed that although the temperament of the people on the two photos is very different, Cheng Feng's judgment is not wrong, it should be the same person.

Liu Yumei's connection with the murderer has finally been found! With a pseudonym, will the real name be far away?

A humble little bar in Q City.

A road pointed out by peers, this is a place with the most pheasants in Q City, and now although it is not cold outside, it is already very cold, and the original station street girls have entered this small bar. Different from the high-end of the bathing center, the pheasants here are either average-looking, or older, and have been in the industry for more than 20 years, which is suitable for asking them for old news.

So Cheng Feng and Wen Mo came to find an insider with little hope.

The two men entered the bar about half an hour apart, and in the dim light of the dance floor in the middle, men and women writhed wildly to the deafening music, and the bar was full of pheasants that were scratching their heads and discharging at each incoming guest.

Cheng Feng was obviously faster than Wen Mo to adapt to this kind of place, and in half an hour, he had already entered the role and chatted happily with a woman in her thirties who was only wearing a bandeau top and hot pants, and she didn't even notice Wen Mo coming in.

The women obviously couldn't attract the interest of the pheasants, and the women looked at Wen Mo a few times, then ignored them and turned to other targets.

Wen Mo glanced at the remaining women on the bar and chose the oldest one to sit over.

This woman's beautifully dyed blue hair was very dazzling in the light, and she was more dignified than the other women sitting on the stage here, Wen Mo felt that maybe it would be easier for her to get some words out of her mouth.

After ordering a beer, Wen Mo didn't talk much nonsense, and took out two hundred yuan and pushed it in front of the woman.

The woman was typing on her mobile phone, and two red hairy grandfathers suddenly appeared in front of her, thinking that she was coming, and the big smile had not had time to fully bloom, and she froze there on Wen Mo's face, hesitated again and again, pushed the money back and shouted: "I'm sorry, I don't do gay business." ”

The music was so loud that Wen Mo didn't want to shout to chat, so she took out her mobile phone and typed a line of words: I'll ask you something, if you know, the money is yours.

The woman was stunned, and then shook her head like a rattle: "I'm not a whistleblower, you can find someone else!" After shouting, he turned around and wanted to leave.

Wen Mo grabbed her, took out two hundred yuan from his pocket, put it on the two coins just now and shouted: "What I want to know is the old things from twenty years ago, just to inquire about individuals, not to tell you, just say if you know, I don't know if I will give you two hundred, okay?" If it doesn't work, you go. ”

Letting go of her hand, Wen Mo looked at the woman. Obviously, the temptation of four hundred yuan is not small, the woman stared at the money and thought for a long time, grabbed the money and stuffed it into her bra, pulled up Wen Mo and walked out of the bar.

"Tell me, what do you want to know?" The woman lit a cigarette and cowered in the cold wind, not forgetting to look around vigilantly to make sure no one could hear them.

"Do you know the woman in the photo? She was in Q City about 20 years ago, and she was your peer, and this should be what she looked like 20 years ago, you think about it carefully. ”

When the woman heard that she really asked about twenty years ago, she immediately breathed a sigh of relief, took the photo and looked at it again and again under the light, and shook her head: "No impression, I won't tell you, I just went into the water not long ago, at that time, the money came from doing this business was really fast, and the people who wore famous brands and bags on the street were chickens, which is like now, I couldn't resist the temptation to embark on this road for a while, and I have been doing it for so many years, people in this line come and go in a hurry, and there are few people who leave their real names, do you still expect to make friends?" I really don't know this person, are you sure she's still alive after twenty years? Looking at her thin and white appearance, she also knows that she is an addict. ”

"What about these people? Do you know each other? Wen Mo took out a few other photos of ** girls to show her.

"This woman, now she is Sang Azhi, the mother of Hongying Bathing City, it turns out that she used to look like this, and she dares to say that she has never had plastic surgery!" The woman only glanced at it, then pointed to the last photo, and said under the pseudonym Wang Jing when she was arrested.
