Lunch is Zhuang Qiang's welcome meal for Xu Zheng, it is not rich, the main thing is that the waste of food here is not good for the leaders to see, and they can't drink, and they can't open up to chat, and after a while, everyone wiped their mouths, and they finished eating.

At work in the afternoon, Xu Zheng was really assigned to Zhuang Qiang's team by Zhang Yuqi.

In fact, Xu Zheng knew about this case when he was in school, and the teachers at that time organized the students to talk about the case, and according to the direction of love, money, hatred, and passion crimes, the students put forward a lot of suggestions in high spirits, and even got in touch with the investigators who handled the case at that time, but unfortunately, the students and teachers who kept restarting the case and the investigators who kept restarting the case did not solve the case.

Five years ago, north of the Yangtze River, in Pubei District, Changming City, not far from the Xiangshan Scenic Area, Huazhu Villa District, A01-18 villas, someone reported that a house in the community was on fire.

The day is 2029, November 07, around 11:50 p.m., when it was raining lightly, the local police station police arrived first, organized manpower to fight the fire, but the fire was too big, until the firefighters arrived, such a large fire water cannon sprayed for more than half an hour before all were extinguished, in this process, the police checked the monitoring of the community and asked the security guard to know that the owner's family had returned home at ten o'clock in the evening.

At the same time, the police quickly launched a search...

It's just a pity that the fire was extinguished, and the evidence in the house was gone, leaving only five black corpses, including a family of four and a nanny.

Because the deceased's villa was close to the fence of the community, a little dirt was found on the fence, the rain was not very heavy, and the murderer's mutilated footprints were also found, and other information, such as camera footage or something, after so many years of looking at the camera footage within a radius of five miles, no suspicious people and vehicles were found.

The only evidence is a few mutilated footprints, but the killer is obviously very professional, wearing the shoes of the deceased and wrapped in shoe covers.

According to the master-level master of the trace examination, through the difference in the undulations of the highlands of the footprints, it is inferred that this person should be a man, about 175 tall and weighing about 72 kilograms...

Then the footprints found by the police elsewhere, this master deduced another result.

All in all, the footprints are very similar to the murderer's misleading, or he knows that it is raining, and the footprints walking in the mud will definitely not be cleared, so there is a suspicion, but I have to say that this person should have a certain amount of criminal investigation knowledge, and there are many ways to say that the footprints are here.

The most puzzling thing for the police is how the murderer escaped from this five-kilometer radius, there is a road outside the villa area, and the opposite side of the road is Xiangshan Lake Park, and this villa area is very rich, the camera in the community can capture this section of the road, but there is no shot of the murderer crossing the road into the park.

The police searched these places several times, and in order to avoid the lights from going dark, even the houses in the entire villa area searched for suspicious people.

No clues left by the murderer have been found in these places, so the police who investigated the case later locked the murderer's escape route in the Malu River not far from here. Don't look at this river, it doesn't look wide, but it is connected to the Yangtze River, and the length is only 4 miles.

Can anyone swim 4 miles on such a cold day?

Xu Zheng can't do it himself, but there must be someone who can, but on such a cold day, if the murderer swims over, will he have to take off his clothes and shoes....

In short, this murderer seemed to have evaporated from the world, and the police force of Changming City at that time exhausted all kinds of investigation methods, and they did not find out where he went.

Talking about the real cause of death of the deceased, the result of forensic identification is that they were unable to escape because they were tied hand and foot by the murderer, and they were stunned by the thick smoke and then the fire made them die directly from lack of oxygen.

At that time, because it was a rainy night and the time was 12 o'clock, the people in the whole community were basically at home, and the neighboring villa did not find any strange shouts in the deceased's home.

Then there is the confession of the security guards, no strangers were found to have entered their community that day, of course, this is also because the people here are either rich or expensive, in and out are driving, driving, Bluetooth automatically opens the door, and the security guards can't see who is in the car.

Xu Zheng has been reading the case file in the office this afternoon, and he has only read one-tenth of it, and the rest is left

There are also records of the investigation of this case by previous waves of investigators, as well as the confessions of hundreds of people in the villa area.

Of course, the most important thing is the life experience of the deceased's family and the nanny, including their work life, as well as the confessions of various characters, and the focus is of course on the investigation records of the people who had conflicts with them.

In short, all kinds of investigations, this murderer is still at large, and at this time, looking at the file, Xu Zheng realized that the various opinions expressed by his young maniacs back then were all on paper.

After taking a sip of water, Xu Zheng began to pack up the files in his office and locked them in his drawer.

He took a deep breath, they only had three months to investigate these old cases, and when there was no result, they would put them back in the cabinet, waiting for the next "detective" to solve them, and the policemen like Xu Zheng who did not solve the case could only provide clues for the later police.

Before, this case was investigated by the two teams, and then Zhang Yuqi was handed over to Zhuang Qiang, Wei Yi, and Ji Meiyue, and now that Xu Zheng is here, she transferred Wei Yi to another team, and then Xu Zheng took Wei Yi's place.

To tell the truth, the two cases restarted by the second team this time are not easy to solve, of course, if they are solved, not to mention what additional rewards there are in the bureau, just the completion of the indicators of this old case can give the task force a large reward, at least tens of thousands, three people, and a lot of rewards.

Like Xu Zheng was in the police station before, only one person caught in a public security case would be given 100~200 yuan.

Of course, there are a lot of old cases, but it is really not easy to detect, Zhuang Qiang and Ji Meiyue went out all day to investigate the scene of the crime, the focus is of course on the road and river, as for the villa after the fire, it is still standing there, which also caused several families near it to move away.

Waiting until 6 o'clock in the afternoon, Zhuang Qiang and Ji Meiyue stepped on the point and came back, Xu Zheng glanced at them, these two people were obviously wrong, and it was very likely that they would take the opportunity to fall in love.

Looking at Zhuang Qiang at this time, the hair of this product really grew a layer of stubble, and when he looked closely, the long hair around his head was cut off, and it seemed that the old Chinese medicine doctor really cured his baldness.

No wonder he was wearing a hat when I first met him today, but his hair was cut and he was 185 tall, so he would be a handsome guy if he wore a police uniform.

At half past six, he was cleaning up and getting off work on time, and he had to invite those friends from the Liulihe Police Station to dinner in the evening.

To be honest, when Xu Zheng left, Niu Panpan didn't have a good time in the institute, at least when he was in the institute, the two of them were used to going on missions, so Xu Zheng specially brought them gifts when he invited them to dinner this time.
