Detective: Start with capturing and retrieving the dog

Chapter 174 Evolution
Knowing the details of the two murderers, and then finding their parents, there are many ways to find them.

For example, asking parents to contact them, going to their usual residence, and pretending to be customers to contact them, these methods are all feasible, but we just need to find the safest method that will not startle the snake.

As for the evidence, as long as people can be caught, it should not be difficult to collect. Go investigate the house that Xu Chenyong built, and you should be able to find the body inside.

Han Xin is not an expert in arresting people, so let the police do the planning.

Han Xin himself is waiting for news from the police at home.

With nothing to do that day, he took Zhao Linshan to the gym to get some exercise.

Exercise helps the brain to secrete dopamine, and it can also maintain good physical fitness when he is a security guard. He can't waste all the cards. The most important thing is that now he needs something to help him divert his attention.

"Okay, let's start." Zhao Linshan patted his shoulder from behind and smiled.

Han Xin turned his head and looked. She was wearing an orange sports bust, her beautiful abdomen had no excess fat, and her lower body was a pair of tight sports leggings. This image caught Han Xin's eyes.

"It's so pretty, you should wear it like this at home." Han Xin touched Zhao Linshan's head.

"This sports bra won't wobble up and down." Zhao Linshan smiled cheerfully, "It's just a little tight."

"Really? Let's jog together." Han Xin greeted with a smile.

In fact, he himself likes jogging on the treadmill. When jogging, he can clear his mind and sort out his chaotic thoughts, and this kind of aerobic exercise can also make people feel better.

Of course, it was actually just to divert attention, otherwise his mind would always be on the case, and he would be very anxious while waiting for the result.

"Now that we have all the information about the prisoners, it shouldn't be difficult to catch them." Zhao Linshan asked while running.

"Should be." Han Xin nodded, "Now it's not like it was in the past. Smartphone penetration rate is so high, no matter what you can't avoid leaving consumption or transfer records. There are more and more monitoring, even those who lag behind The city surveillance also covers most of the area, and people should be able to catch people without accident. Unless they..."

"Aiya." Zhao Linshan interrupted him by poking his face, "Don't be crow-mouthed, I hope it goes well."

"Yes." Han Xin nodded with a smile, but he was still a little worried.

The couple worked so well together before, and almost everything was perfect. After that, the methods became more mature, and the chance of making mistakes should be smaller.Did the police really have a chance of catching them?Even if caught, can you find evidence?

Han Xin had a bad feeling about this.

After returning from the gym, Han Xin and Zhao Linshan had dinner, interacted a few times in the evening, and then took a rest.

However, the next day, as Han Xin expected, the result was not so good.

The police pretended to be a customer and contacted Xu Chenyong's current mobile phone number under his ID card, saying that it was recommended by the previous owner, Hu Kun, and wanted to consult the two couples about building a house, but the other party replied that they no longer Do it now.

When the police asked what they were doing now, the other party hung up the phone.

Of course, the police will not only use this method, so they investigated the consumption records of the two, but found nothing.

The bank cards under the two ID cards have not had any consumption records since three years ago.

The last transaction record three years ago was a transfer of more than 400 million yuan. According to the investigation of the police, it was found that they had sold the 200-square-meter duplex in Shachang City before, and there was nothing after that.

But it is still inconvenient to live on cash alone in this era. The police estimated that they stole someone else's ID card information to apply for a bank card, and it may be a distant relative.Both of them are big families, and there are many people who have gray income due to occupational problems. It is really difficult to check them one by one.

"Sure enough." Han Xin sighed on the phone side: "It is true that the world has changed, and their modus operandi must also evolve accordingly, to find a modus operandi that can adapt to the current environment."

"Then Mr. Han, what should we do next?" Huo Gang said distressedly over there: "I'm sending someone to check the consumption of bank cards under the names of their relatives to see if they can find anything unusual."

"I expected it to be like this." Han Xin smiled here, "They can hide themselves, but their psychology has been figured out by me, so I can infer what they are doing. Give me a little time Think about it, when there is a result, I will call you again?"

After hanging up the phone, Zhao Linshan frowned and said, "Didn't find it?"

"Their methods have evolved." Han Xin nodded, "This is also very normal. After all, this era is advancing, and their methods must of course also improve. Otherwise, how can they be in this world full of mobile payment and surveillance cameras? How about continuing to get away with it? And the more crimes they commit, the more proficient they will be, and they will definitely think of better ways.”

The couple had already developed such a sophisticated modus operandi six years ago, it makes no sense that six years later there would be no progress.

First of all, the couple will move in a place that is relatively poor but suitable for tourism; second, they will find a way to avoid a large number of surveillance equipment in the urban area; finally, their method of handling the corpse will not change, and they must still seal the corpse in the wall. After all, this is the best method they have researched for so many years.

So, combining these three points, how might these two men improve their modus operandi?

A poor, backward place, avoiding the inner city area to commit crimes where there are no cameras, and the dead bodies will be sealed in the wall to indicate the need for construction in progress.

Han Xin closed his eyes: If he were these two murderers, what would he do to perfect his modus operandi?

"They are serial murderers, so they must not stay in one place all the time, so what will they do if they want to run projects everywhere without making people suspicious?" Han Xin paced back and forth, and then a thought flashed through his mind .

"Project Hope, or some other charitable organization!" Han Xin said to himself, "They go to poor areas for charity, such as Hope Primary School or hospitals. In poor and backward areas, there are foreign tourists, so he can dispose of the corpses Who would doubt that a great benefactor who does charity is a serial murderer? Perfectly meets all their requirements!"

Although there is no definite basis, if Han Xin is such an excellent serial murderer as them, he will choose this way.

Zhao Linshan nodded and said, "That makes sense, and if it's a charity, you can entrust others to buy the materials they need. Their daily diet and daily life also follow the group, so there will be very few consumption records left."

Han Xin then immediately called Huo Gang: "Captain Huo, investigate those places that have the Hope Project or similar charity construction projects, and then pull out the files of the women who disappeared that year there."

"Do you suspect that they are going to do charity projects?" Huo Gang asked, and then he understood Han Xin's meaning: "It turns out that this is indeed a good cover. It can not only allow them to continue their previous crime style, but also put an end to them. Leave consumption records and surveillance videos. And this charitable gimmick will make it easier for them to gain the trust of victims..."

As he said that, Huo Gang replied: "I'll go and investigate right away!"

However, it is still unknown whether Han Xin's method can find the couple, but it can only find out their trajectory in the past two years.Right now, at this moment, the couple may be on their way to the next city, or they may have already fled abroad. These are uncertain, and all he can do is to follow the trajectory of the couple.

"Oh, this time the video of this case, I will divide it into five parts and finish it, and then leave enough time for me to prepare the next video." Han Xin covered his forehead and sighed, "As a UP master, I'm still too much. It's tender."

"It's okay, don't you have experience in the future? Cut the case into multiple videos, and you can post them for a while, so there won't be such a long blank period like now." Zhao Linshan said with a smile.

"That's right." Han Xin touched her head and smiled, "Our detective couple must catch this murderer couple."

"That's right!" Zhao Linshan waved her small fist full of fighting spirit.

The investigation time this time will be relatively long, until the next afternoon, when Huo just informed Han Xin to go to the Public Security Bureau to test their investigation results.

Han Xin knew that Huo Gang must have discovered some useful information, so he needed him to go to the scene.

Sure enough, when Han Xin brought Zhao Linshan to the Public Security Bureau, Huo Gang excitedly raised the file in his hand: "It's exactly the same as you guessed! In March 2018, in Huahuai City, a book donated by a rich man Since then, there have been a series of cases of missing women in the local area, most of whom are tourists who went out on vacation!"

"Huahuai City is also a city more suitable for tourism." Han Xin mused.

"And this project was only completed in November 2018." Huo Gang added: "Now he should have started the next project, and it is very likely that this project is not finished. Then we discovered..."

With that said, Huo Gang slapped a file on the table, and said with an excited smile: "Ganghuang City! There is a Hope Primary School under construction there, and this is a woman who disappeared after traveling there. Do you think it is the same as that Bastards pick similar targets!"

Han Xin looked at the three missing women. Eye shapes and hairstyles may be slightly different, but they all have high cheekbones.After all, the eyes can be blindfolded, and the hairstyle can be adjusted.

But this also means that the murderer has begun to relax his conditions, which is a manifestation of being dominated by desire.

"The local police are already on their way." Huo Gang smiled excitedly, "Try to catch them back today!"
