Shen Mingyu came to the Luckin Coffee shop he often buys, Luckin Coffee is a brand that has only become popular in the past two or three years, mainly at civilian prices, but civilians are actually not very civilian, more than a dozen yuan a cup, a little bit more ice cubes, but fortunately, the taste is not bad, Shen Mingyu is a loyal customer of Luckin Coffee, and he has to buy it three or four times a week.

He drank coffee and looked out the window at the traffic, and he began to think: Jian Yiyi's background had been fully investigated, her interpersonal relationships were simple, and she had no enmity with anyone.

Usually at work, at home at two o'clock and one line, go to the park to exercise at night, girlfriends are not local for the time being, and most of them are at home or go out with Lu Ji when they rest.

Could it be attacked by someone who made a temporary move, it's not quite like it, if a stranger meets a woman who has a bad idea temporarily, it's nothing more than wealth and sex.

But Jian Yiyi did not lose money or be violated, is it just revenge for the indiscriminate attack of society?

Generally speaking, this kind of revenge on society is extremely twisted, and after they succeed once, they will intensify their search for the next target, and the time between the two cases will become shorter and shorter, because these people's hearts need this perverted behavior to fill.

However, it has been almost two days, and I have not received any news that other people have also been attacked, could it be that this indiscriminate killer has not started committing crimes.

At present, Shen Mingyu can only think of this possibility, he told Zhang Jiaqian his thoughts, Zhang Jiaqian said that he would let his subordinates do their best to investigate whether it was an indiscriminate attack, Dark Ash County is a small county, and it should not take long to complete the investigation.

Shen Mingyu still doesn't feel like an indiscriminate attack, there hasn't been a big case in Deep Gray County for a long time, could it be that he ran into it as soon as he came over?

That's lucky. Shen Mingyu was about to call Han Sicheng to report the current situation and progress at this time, but Han Sicheng also had a tacit understanding and also dialed his phone at this time.

"Hey, Xiao Shen, what's going on with you over there, is it a tricky case they said?"

"It's really a bit tricky, I don't have a clue at the moment, the relationship between the victims is simple, but everyone has an alibi, and the husband is even more away in the light red city on a business trip...... At this stage, we are investigating in the direction of indiscriminate killing, but I feel that we will eventually hit a wall. ”

"When you talk about Qianhong City, I have a classmate who is in the Qianhong City Public Security Bureau, and she told me that they also have a case there, and there has been no progress for two days, what a coincidence."

"Wait, the victim Jian Yiyi's husband Lu Ji has been on a business trip in Light Red City for the past few days, and he only came back today, right?"

"It's impossible, Lu Ji is just going on a business trip, and besides, he went to Light Red City, so what's the situation with his wife?" Han Sicheng felt that this direction was wrong and retorted.

"You have a point, it's really impossible to think about it, but now there are no clues and clues, I'll follow up on this a little, I'll communicate with the Forestry Bureau later, you tell your classmates, I may have to go to Light Red City." Shen Mingyu replied.

"You're not mistaken, Light Red City is quite far away from City A, but since you said so, then I'll talk to my classmates at that time, you have to see if the Forest Bureau agrees, you yourself tell him, don't get involved with me." Han Sicheng said.

After hanging up the phone, Shen Mingyu thought carefully about his thoughts, there was also a murder in Light Red City, which happened to be at this point in time, and Jian Yiyi's husband Lu Ji was also in Light Red City these days, is it really a coincidence?

Anyway, let's ask Lin Guang first.

"Hey, Forest Bureau, I have something to tell you."

"Xiao Shen, what's the matter, you can tell me." Shen Mingyu told Lin Guang what happened on the phone, he thought that Lin Guang felt that his idea was just a guess, and it was time-consuming, laborious and expensive to go to the light red market, who knew that Lin Guang said: "Your idea is very unique, after you analyze it like this, I feel that there may be something strange in it, you can go to the light red market with confidence, I will contact the people over there later, and someone will receive you at that time." ”

"Know, know, Forest Bureau, promise to complete the task." Shen Mingyu didn't expect Lin Guang to not only support his idea, but also agreed so simply, and even prepared to contact the Qianhong City Public Security Bureau in advance.

He is worthy of being an excellent leader in the mouth of others. Shen Mingyu planned to go back to the Deep Gray County Public Security Bureau to explain the situation to everyone first, but they didn't know the situation in Light Red City yet.

When he came to the Public Security Bureau, Zhang Jiaqian was reporting the situation and assigning tasks to everyone. He saw Shen Mingyu coming over, and hurriedly beckoned him to come over for a meeting.

Shen Mingyu first reported the information he got to everyone, and then he also told everyone what he had just learned about the situation in Qianhong City: "Everyone, I heard that there is also a case in Qianhong City, and the colleagues over there are also clueless, the situation is a bit similar to ours here, and I will ask them in detail when the time comes, I suspect that these two cases are related, so I plan to go to Qianhong City to understand the situation, and I will report to you in real time." Here, you'll need to keep an eye on Landing to see if he's going to behave suspiciously. Zhang Jiaqian nodded, and then conveyed the situation to the other police officers.

Bidding farewell to Dark Gray County, Shen Mingyu Starry Night stepped on the high-speed train to Light Red City. After several hours of running, Shen Mingyu came to the light red city, the light red city is a famous ancient capital, you can see a lot of ancient buildings as soon as you go out, and there are usually a lot of tourists, it is a typical tourist city.

Shen Mingyu was waiting for his colleagues from the Light Red City Public Security Bureau at the station, and at this time a girl came over, although she was not wearing a police uniform, but Shen Mingyu could clearly perceive her sharpness and ability, she must be a policeman.

"Hello, are you Xiao Shen, I am Han Sicheng's classmate, and I am also from the Qianhong City Public Security Bureau, my name is Luo Ning." Luo Ning, a native of Qianhong City and Han Sicheng's college classmate, has a very good relationship with each other, and usually exchanges experience and case-handling experience with each other.

"Hello, I'm Shen Mingyu from the Public Security Bureau of A."

"You don't need to introduce it, I heard your story from Han Sicheng, and he often praises you." Shen Mingyu thought to himself, Han Sicheng, this BYD, would still praise people.

"I'll take you to our bureau, and then I'll tell you about the case here." Luo Ning took Shen Mingyu back to the Qianhong City Public Security Bureau, because Lin Guang greeted him in advance, a group of leaders were waiting for Shen Mingyu's arrival at this time, Shen Mingyu saw this pomp, his legs were frightened, but he still pretended to be calm, greeted everyone, and talked about the purpose of his coming to Qianhong City: "Leaders and colleagues, thank you for your warm welcome, today I came to Qianhong City, mainly to investigate and understand the case that happened in Qianhong City in the past two days, I heard that you have no clue about the suspect, just right, I've been dealing with a case in Deep Gray County these days, and it's similar to the case you encountered, but I can't find the suspect, and the victim's husband has also been on a business trip in Light Red City, I think these two cases may have something in common, maybe you can find clues to help solve the case, so I need your cooperation. Immediately afterwards, Luo Ning introduced the case that occurred in Qianhong City to Shen Mingyu: "The deceased Ying Tianqi, 35 years old, was self-employed, and opened a bakery in Qianhong City, and the bakery was only less than a kilometer away from home, so the deceased walked home. The time of death, which was around 10 p.m. the night before, was strangled to death, and there were traces of struggle before death, and she was killed on the way home from the bakery closed. The murderer should have followed all the way or knew Ying Tianqi's route home very well, the scene of the crime was in a deep alley not far from his home, and if he walked out from here, he could reach the deceased's house faster. We also investigated the relationship around the deceased, the deceased's parents died early, there were no brothers and sisters, there was only one aunt who saw him once every six months, but the aunt lived far away, the deceased had three girlfriends, but the three girlfriends had alibi certificates that day, we have investigated, the deceased did not have children, and lived with her husband in an old community. The deceased's husband's name is Yan Jiancheng, who works as a buyer in a food company, and he was shopping for local specialties in Shenshen County at the time of the incident, and he only rushed back overnight after we informed him yesterday. We also searched the scene for a long time, but the murder weapon was found, it was a hemp rope, on which there were traces of the deceased's teeth, it seems that it was left when he was struggling, and the others have not found any clues for the time being. We also asked the neighbors and the staff of the bakery, and they all said that the deceased was usually approachable and easy to talk to, and the regular customers would get a discount on their bread, and the employees also felt that the boss was very kind and willing to work with her. Usually there is no enmity with anyone.,It's just an ordinary small shopkeeper with a simple life.。 After listening to Luo Ning's description, Shen Mingyu felt a little strange, this is too much of a coincidence, when the two deceased died, the husband was on a business trip or errand, and the place happened to be the place where the other deceased died.

However, coincidence is coincidence, and Shen Mingyu currently has no evidence to prove that there is a connection between the two cases.

First of all, it should be impossible for two couples to know each other, one is far away in Light Red City, the other is in Dark Gray County, and it is difficult to get in touch with two places where the eight poles can't be hit, and it seems that nothing can be proved just by the fact that they are on a business trip.

But Shen Mingyu always felt that things were not so simple, and there might be something hidden behind this coincidence.

Shen Mingyu proposed to go to the scene of the crime to investigate again, Luo Ning agreed to him, and took Shen Mingyu and a few colleagues to the scene of the crime.

The scene of the crime is a small alley, the alley is about 200 meters long, and you can see the community where Ying Tianqi lives through the alley, which is only a few hundred meters away.

If you follow the ordinary route from the main road, it will take about twice as long, so Ying Tianqi chooses to pass through the alley, there is no sunlight in the middle of this alley, and it is dark even during the day, let alone at night, this alley is a part of the old street, most of the people who live here are some old people, they are all people who have lived in the old street for decades, and they are not willing to move away like this, and the children can only let them continue to live here, and come back to visit from time to time.

The police had already questioned the residents in advance, and on the night of the crime, it was already past 10 o'clock, most of the old people were sleeping, and the elderly had hearing loss, and it was normal for them not to pay attention to what was happening in the alley, so they did not get any useful information.

Shen Mingyu felt that the murderer should have been ambushed here in advance and waited for Ying Tianqi's arrival, but there was almost no light in the alley at night, how did he determine the target?

Or did he find Ying Tianqi some way ago and knew that he would enter the alley, so he hid in the alley in advance, which means that this person knows Ying Tianqi's schedule and route planning very well, knows that she will go home from the bakery at about 10 o'clock, and knows that she is walking home.

But it's strange again, people who know his route and routine have alibi, could it be that someone has been eyeing her for a long time and follows her home every day?

But I haven't heard her say that she is being followed. Shen Mingyu was confused, Luo Ning asked him if he had found anything new, Shen Mingyu shook his head helplessly,

"I have an idea in my heart, but that may be a bit, and I haven't decided yet, so I won't think about it for the time being." Luo Ning smiled and said, "It's okay, you say it, let's discuss it together, maybe there will be new discoveries." Oh, I see, does Han Sicheng often deny your ideas? ”

"How do you know...... I can't say often, I can only say that every time, but when my conjecture was correct, he pretended to be dead again, so I'll talk about my own thoughts, I personally think that Ying Tianqi's case is related to the case in Dark Gray County, because it's too much of a coincidence. If you think about it, both husbands went on a business trip at the same time, and they happened to be in the city where the victim lived, and the two victims were killed almost at the same time, and the familiar people around them all had alibis, if there were not so many things in common, I might still think it was a coincidence, but the two cases were extremely similar, and I only had one thought, that is, to exchange killings. Luo Ning couldn't help but be surprised when she heard the words "exchange killing",

"You have a point...... But can this really be realized, not to mention whether the two husbands recognize each other or not, even if they do, can they be willing to do these things for each other, in case which party instigates it first, it will not be exposed immediately. (Exchange homicide means that if the murderer kills a stranger who has no grievances with him, then the probability of the police finding the murderer according to clues will be greatly reduced.)

So suppose there are two murderers, each of whom has a target they want to kill. Then the two of them agree to kill each other who they want to kill, and they can achieve an unmotivated killing.

Shen Mingyu thinks that Luo Ning is reasonable, the reason why exchange killing is just a concept is because it is difficult to implement, and it requires two murderers to make up their minds and trust each other to complete, and the exchange of killing methods is not the key, the key is the motive and alibi, and the lack of motive will indeed increase the difficulty of the police in handling the case.

Shen Mingyu said: "Sister Luo, what you said is indeed good, but there is no clue at the moment, and I can only go in this direction first, I am responsible for following up this clue, you are responsible for keeping an eye on Yan Jiancheng, and I will also contact the police in Deep Gray County, I have a hunch that this case is inseparable from the two husbands." ”
