Dawan Village, Shahe Town is located to the west of Changyang City.

Similar to other towns in Changyang City, the pillar industries of Shahe Town have long been transformed into real estate and processing industries. Dawan Village has also built factories, dormitories, and rows of self-built houses. .

"The floating population is 11 to 11, and there are several vegetable markets." Standing at the scene of the incident, the director of the Shahe Town Police Station introduced, saying: "[-] years is too long. In the factory, half of the people who work in the factory are local young people. Now, the locals are not willing to go to the factory, and the vegetable sellers are not locals anymore.”

"What do the locals do?" Liu Jinghui asked.

"Be a landlord, open a supermarket, run a restaurant, set up a mahjong parlor and so on." The director of the police station said, a little envious, said: "These self-built houses were not in charge before. A family with dozens of rooms is not in charge. Yes, a room costs two or three hundred yuan a month, do the math, and your income is higher than mine.”

"Twenty-three hundred yuan for a room is quite cheap, and it is one or two thousand yuan in the city." Wang Chuanxing came from another place. Hearing the rent in the town, he felt that it was quite good.

Jiang Yuandao: "Water and electricity bills will be charged. 100 yuan per month, and 150 or 200 yuan for more, so the rent will be four to five hundred."

"The rent is 200, and the utility bill is 200. That's too harsh." Wang Chuanxing was speechless.

"The 200 yuan utility bill can include sanitation fees, management fees, and a shared network cable. Just use a separate mobile phone number and set up a broadband for the rooms on the first floor. Tenants are generally happy. , because it costs dozens of yuan to pull the network cable alone, and it is very troublesome, and the self-built house does not have a production certificate, so it is not easy for them to go." Jiang Yuan described it in detail.

The so-called Rome was not built in a day, and the Romans naturally did not entrust their houses to intermediary companies on the first day. Comrade Jiang Fuzhen, for example, learned to be a landlord when he was demolished for the first time.

When people in Jiangcun first rented houses, they also rented them to workers in nearby factories.

Wang Chuanxing had also known Jiang Yuan's identity before, and when he thought of it, his eyes couldn't help but look a little sideways.

Liu Jinghui coughed twice, and brought the topic back: "In short, there are a lot of migrants in Dawan Village, and it is unnecessary to conduct a general investigation now."

Wei Zhenguo followed Jiang Yuan all the time, and at this time he also joined in and said, "Isn't the taxi abandoned 5 kilometers away? In theory, from Dawan Village to the abandoned point, and the surrounding areas, could be the murderer's destination at that time... However, Is it impossible to find it?"

Liu Jinghui shook his head and said: "From the method of committing the crime, the fact that the DNA left behind has never been able to match, and the fact that the murderer has not been arrested again, and the investigation of the released prisoners during the current case, I think, The perpetrator is most likely not a repeat offender, and may even be a first-time offender."

Pointing ahead, Liu Jinghui said: "For a first-time offender, the first scene where the body is located is more likely to be the destination of the two. , and there is no suitable hiding place nearby."

Liu Jinghui made a concluding speech: "Killing people is better in a familiar place."

In fact, this is also the development of the times.

With the popularity of cameras, or changes in society.Personal residences have become modern people's favorite places to kill people.

A more comfortable expression is: as long as you leave your home and don't go to other people's homes, your chances of being killed will be greatly reduced!
It is equivalent to saying: staying at home is easy to die!

Wei Zhenguo was a little puzzled and said: "If this is their destination and they want to avoid being discovered...they are going to abandon the car anyway, why don't they move the body away?"

"This shows that they are novices. I think they didn't think about it, or the corpse is too disgusting?" Liu Jinghui said: "Actually, a robbery is a robbery, not necessarily a murder. If a murder is caused during the robbery, normal robbery The criminal, either did not deal with the scene, or just drove away directly, fled farther away, and then changed cars or took public transportation. Abandoned 5 kilometers away..."

Liu Jinghui shook his head: "It can only be said to be a panicked choice. I drove away in a panic. After driving for a few kilometers, I felt that I was too far away from the destination, so I abandoned the car and fled. Then, with a high probability, I fled.

"

"How can such a case be solved?" The director of the local police station was dumbfounded.

The current cases are more straightforward.Moreover, the twists and turns of many cases are only the twists and turns of the criminal himself. To the police, it is purely taking off his pants and farting, which is the first time he shows his fart.

Liu Jinghui has seen a lot of buttocks, and now he pondered, and said: "The original household registration information is also incomplete."

"That's for sure."

"Tickets must be real-named, what about train tickets?"

"Maybe I'm taking a bus or a train ticket here... I don't know if it's better to check the train ticket from 11 years ago." Listening to Liu Jinghui's words, Wang Chuanxing felt that all the work would be accumulated on his own head, so he hurriedly took precautions Needle.

Wei Zhenguo said: "If we can find a way to pull out a list and list the people who moved within a certain period of time after the incident, the case will be simple."

Tang Jia asked: "Didn't the task force do this at the time?"

"At that time, the task force did not have a clear judgment on the suspect's residence and the destination of the taxi." Liu Jinghui shook his head: "Furthermore, they are not sure whether the murderer has fled."

Jiang Yuan nodded slowly.In fact, from the evidence he saw, he was not sure where the murderer lived or where the taxi was going.

This part of the content is not supported by evidence, it is Liu Jinghui's reasoning.

In an ordinary task force, even if someone can give the same reasoning, but the trust level is not enough, and the status is not enough, they will not be considered emphatically.

Liu Jinghui looked at Jiang Yuan and asked, "Jiang Yuan, what do you think?"

"The bloody footprints left at the scene are very clear, and I can sift them. However, there was only one bloody footprint left at the scene...in fact, it was repeated with DNA." What Jiang Yuan said is also one of the pain points of footprint science. Decades ago, it was possible for footprint science to follow the path of fingerprint science, but after the advent of DNA technology, identification methods including fingerprints were downgraded.

In fact, Liu Jinghui just wanted to confirm Jiang Yuan's thoughts, and seeing that he had no suggestions on the direction of investigation, he said: "Now, if there are only these clues, then I think it is really not easy to solve the problem. It is better to lure the snake out of the hole and think of a way to put This murderer hooked up..."

Not only Jiang Yuan, but everyone present frowned.

It's not that he doesn't trust what he said, but that these words seem to be heard by several people not long ago.

It seems that when Jiang Yuan first called him over because of the case of burning bone fragments, Liu Jinghui said similar things.

Or, exactly the same?
Everyone calmed down for a moment.

Neither Jiang Yuan nor the others' cell phones rang.

Wei Zhenguo looked at Jiang Yuan, and then said to Liu Jinghui: "Liu Chu, what is your method?"

Liu Jinghui gave an "en" and said, "I think the murderer should still be very concerned about the case here. We can announce that the case has been reopened, we have found new clues, and then, using the new clues, we can hook the two people out." .”

"What new clue?" Wei Zhenguo asked curiously.

"Well... First of all, I want to say something. I think the most likely composition of the murderer is a husband and wife, or a boyfriend and girlfriend. There is a very small probability of three people, two of whom are husband and wife." Liu Jinghui's expression With a little bit of struggle, his reasoning has always been unconstrained, but there are not many opportunities to have such a good detection environment.

Liu Jinghui spoke of his own judgment very seriously, and then said: "We can say that the murderer had a concubine, and some time before the crime, he might have had something to do with the concubine, or even say that the concubine had a child... Come on, there must be a lot of chaos in the house of the murderer who is paying attention to the situation here. As long as there is a change... there is a change, it will be easy to be discovered."

"Maybe, one of them directly reported the other?" Tang Jia quickly thought of one possibility.

Liu Jinghui nodded, and said again: "Of course, you can't count on this, but I think this will definitely attract the murderer to pay attention to this case, and maybe a flaw will be revealed."

"Just that, I'm afraid it's not enough." Jiang Yuan looked a little pessimistic.

Tang Jia immediately turned his back and said, "Yes
Ah, maybe the murderer is already divorced, 11 years later, he went out, maybe he can't find a job..."

"Then add a reward, and increase the reward a bit. Maybe the divorced wife will report her ex-husband." Wang Chuanxing hammered his left palm with his right hand.

"Then send yourself to prison together?" Tang Jia despised Wang Chuanxing with his IQ.

"Uh, yes... 30 is not worth an indefinite period." Wang Chuanxing bowed his head silently.

Wei Zhenguo saw the dignified expressions of several people, couldn't help but smiled, and said: "At least, our progress has surpassed the special case team, and we can do what the special case team couldn't do at the beginning. , or the nearby villages, or even the entire Shahe Town, make a list, look for those who left after the crime, try to list as many people as possible, and then do DNA..."

"We did a similar investigation in the later stage." Liu Jinghui emphasized: "If we want to use investigation to find the murderer, we are no match for the special case team at that time. Besides, didn't Jiang Yuan propose that the murderer was lame?"

"Then just look for people with lameness. There shouldn't be many people in Shahe Town." Wang Chuanxing felt that his IQ had regained the high ground.

Liu Jinghui sighed: "I keep talking about the destination of the taxi. I don't know if you have noticed. In fact, I think the criminal's destination is indeed near Shahe Town, but it doesn't mean that the criminal must live in Shahe Town for a long time. It doesn’t even have to be rented in Shahe Town, maybe it’s just to visit relatives or friends or to seek refuge with relatives?”

When he said this, Wang Chuanxing, who just felt a little eyebrow, suddenly turned dark.

As a young man who was admitted to the Changyang Municipal Bureau through his own efforts, Wang Chuanxing was quite confident in the criminal police team.

However, the backlog of homicide cases is indeed a bit beyond the outline.

"Then what should we do now?" Wang Chuanxing looked at the others.

"If the judgment of lameness is true..." Liu Jinghui looked at Jiang Yuan, then at the factory not far away, licked his lips, and said, "Then investigate secretly first."

This is very different from the investigation direction Liu Jinghui mentioned earlier, Wang Chuanxing couldn't help but said: "Why?"

"Because if the murderer is not a local, the person who knows about the murderer's lameness is likely to be a relative or an old friend of the murderer. In short, he is someone who has a certain social relationship. A vigorous investigation may make the insider worry. ..." Liu Jinghui said up to this point, "Of course, the core is still lameness..."

"The left leg is short and the right leg is long, so he has experience with knives." Jiang Yuan gave an affirmative answer.
