Detective: Start with capturing and retrieving the dog

Chapter 172 High IQ

Although the investigation has once again reached a dead end, it is not without results. They have a better understanding of the murderer and know that he is the person in charge of taking over the project and designing the house.

In addition, I also learned that the murderer's economic conditions and appearance conditions are relatively superior, and he will go to talk to the women he likes.

With these characteristics, the image of the murderer will be much more specific, and it will be much easier to find him in the future.

"He's a foreman, so all of this makes more sense." Han trusting his chin, he muttered to himself, "He must be a confident and attractive man, and he would strike up a conversation with the victim. Then, why does he miss his ex-girlfriend so much? ? Was he dumped because he had no money? But his family should be relatively rich..."

Han Xin shook his head immediately. Now is not the time to think about these things. To solve this case, one must start from the direction where clues can be found, and now he has basically figured out the murderer's mode of action.

First of all, the murderer was introduced by acquaintances, and moved between various backward cities to work.He himself acts as a foreman and is responsible for purchasing materials, and then recruits people to work locally after receiving the job. This can ensure that each batch of workers is different, and no one will find out those "little hands and feet" he did in the project.

After confirming the target, he may first track the target, and then create a chance to meet him and strike up a conversation with him. If the conversation is successful, he will find an opportunity to take the other person back to his local residence and commit a crime.

Therefore, there is an obvious investigation point: since he is looking for targets at the train station, he must be often photographed by the train station's surveillance, and the train station staff must often see him.

According to this point, go to the train station in Shenshi to investigate, maybe you can find something.

However, six years have passed, and most of the videos from that year have not been preserved.

Fortunately, their previous work was not in vain. Among the few missing women selected based on their appearance, one disappeared only in October 2018, during the National Day holiday.

Moreover, this girl's appearance is particularly obvious, she is [-]% similar to a previous victim, and it is very likely that she is a victim under the hands of the same person.

The girl's name is Li Fang, and the missing city is Yonsei City, a city that is very suitable for tourism but relatively backward in development. The famous Wudang Mountain is here.

Like Shen City, Yonsei City is restricted by terrain, so the transportation is not developed. Slowly, the local automobile industry moved to other places, causing the local economic development to gradually lag behind.

Moreover, Han Xin noticed that Yonsei City is also a city in Bukho Province, and it is very likely that the murderer is only active in Bukho Province or the surrounding areas: because the murderer has his own "hunting ground", only in this hunting ground can he feel safe.

"It happened last year, so the local train station should still keep the video from that time, and this person often comes to the train station, the staff of the train station must have an impression." Han Xin suggested to Huo Gang.

At this time, Hu Chen came back from the technical department and got back the identification results of the corpse.

"Mr. Han, a large amount of formaldehyde was detected on the corpse, but it was not formalin." Hu Chen said with some disappointment, "The main component of formalin is formaldehyde, so formaldehyde can be used to embalm the corpse And formaldehyde is not a rare material, many decoration teams use formaldehyde in their homemade paint, so this route is probably impossible to find.”

"Good guy, high IQ..." Han Xin couldn't help sighing.

Although he knew that the murderer was extremely vicious and shouldn't give him a positive evaluation, the thoughtfulness of the other party was indeed admirable.

Quicklime and formaldehyde, two common materials in home decoration, are used to complete the treatment of the corpse. No one will doubt the purpose of buying these materials as a home improvement person.

This murderer was perfect in almost every aspect.

From this point of view, there may not be any information found at the train station, and the murderer may have disguised himself when he went there.

Since the local police needed time to investigate, Han Xin took Zhao Linshan home first.

"Hey, thinking that such a serial murderer might be around us right now, I feel a little creepy." Zhao Linshan said while changing her shoes, "So girls must protect themselves."

"Especially like you." Han Xin patted her upturned buttocks, "Pretty but heartless."

"I have no heart for you!" Zhao Linshan said unconvinced, "Let a stranger come to me and try!"

"Let's think about what to have for dinner." Han Xin kissed her on the forehead, "How about some fried noodles?"

"Yes, you can do it." Zhao Linshan blinked at him cheerfully, "Then I will squeeze the sauce for you at night."

"It's a deal." Han Xin touched her head and smiled.

While cooking, Han Xin also had time to relax his mind. He was still thinking about one thing: If the murderer can successfully strike up a conversation with these girls, it will be a matter of time before he has sex with them. Why did he kidnap them and sexually assault them? And then kill it?This may seem contradictory.

Is it to vent your anger on your ex-girlfriend?Han Xin frowned and thought to himself, then shook his head: he felt his mind was muddled.

There were so many things in this case that didn't make sense, like a ball of thread that was tangled up indiscriminately but couldn't be untied, which made him very upset.

When I figured out that this person was the foreman in charge of this project, it was like untying one of the knots. The logic in many places became much smoother, but it also brought more knots.

Han Xin took a few deep breaths to drive this irritability out of his mind: Take it easy, it will always be smooth.

After dinner, Han Xin discussed the case with Huo Gang and others again, but still found nothing.After all, there are still too few clues at hand. We can only see if the police in Yonsei City and Shen City can find anything to help them advance the case.

However, at eleven o'clock the next morning, Huo Gang received an investigation report from the local police in Yonsei City.

Whether it was the impression of the local train station employees or the surveillance video of the train station, there was no such a man who often came to the train station to hang out.

And this also cut off their clues again.

"Mr. Han, what should we do now?" Huo Gang said distressedly over there, "The formalin road is also broken, and the train station has no results, and there is no more information from the previous owner. I can't check it anymore."

"Then let's use the original method." Han Xin said with a sigh, "Continue to search for the crimes he may have committed in the past, and especially to find those corpses that were not processed and sealed in the wall, but they died because of decay. The circumstances of his discovery. It is best to ask the public security departments in all provinces across the country to inquire, as he may not have committed the crime in a backward city at that time.”

"This is a lot of work..." Huo Gang sighed, "I'll do it now."

Of course, Han Xin also knew that this was a heavy workload. After all, he searched in archives all over the country, and more than six years have passed since now, so it must not be easy.

But this is the only route they can continue to investigate now, otherwise they can only wait for the murderer to make another mistake.Given that the murderer's modus operandi had been so perfected six years ago, this possibility was very low.

Therefore, it is very likely that this case will eventually become an unsolved case, which makes Han Xin restless.

"Oh, don't be like this. This case has been going on for too long, and it's normal to not find out the results." Zhao Linshan comforted him by touching his head, "You can't solve all the outstanding cases. .”

"I know." Han Xin put his arms around Zhao Linshan's shoulders, "I'm annoyed not because I can't catch people in this case, but because I can't figure out the logic inside. I always feel that there are many things that are not right, and I can't deduce this. The psychology of the prisoner. What is his purpose? Why would he sexually assault and kill the target even though he succeeded in striking up a conversation?"

"Okay, okay." Zhao Linshan kissed him on the face, "Let's play games and divert our attention. You can think about what video to shoot in the past few days and send it out to satisfy fans."

At present, he has spent three days on this case. Counting the follow-up of Yu Chusheng's case before, he has not updated any video for ten days.

He also knew that he should release a video first to deal with fans, but he didn't have that thought.

At this time, whether it is making money or popularity, it is not as important to him as the "truth".

So, in the afternoon, Han Xin still came to the Public Security Bureau, and together with Huo Gang and others, screened out the cases that might be the same murderer from the many cases.And Zhao Linshan simply brought the computer over this time, and worked with him.

At about three o'clock in the afternoon, Hu Chen hurried back from the technical department.

"Mr. Han, Mr. Han..." Hu Chen panted and raised the report in his hand: "The technical department has made new discoveries! They found traces of polyethylene in the victim's lungs." Material!"

"Polyethylene, I remember..." Han Xin raised his eyebrows.

"The material of the plastic bag?" Zhao Linshan was also a little surprised, "Why are there those materials in the lungs?"

Hu Chen drank half a glass of water before continuing: "This means that the deceased had been covered with a plastic bag before his death, and the plastic bag was bitten through and inhaled into the body while trying to breathe."

"But they were strangled to death, right?" Han Xin asked tentatively.

Hu Chen shook his head: "It's hard to say, the deceased's neck was under heavy pressure, and the cause of her death was suffocation. So she may have been strangled to death, or she may have been strangled by someone and then smothered to death with a plastic bag."

"Repeatedly suffocating the victim is abuse... something is wrong." Han Xin narrowed his eyes and muttered to himself, his mind was still muddy, but he had a feeling that he was about to grab something.

The point of untying that knot is very close.
