drove away Guo Jingfei, who asked for money, and Xu Yuan's mobile phone rang again.

It is the criminal investigation commissioner I met two days ago when I was recording the investigation, Hu Yimin.

"Xu Yuan, I'm Hu Yimin, do you remember? Didn't we say last time that there are cases that can be exchanged? I wonder if you are free now?" Hu Yimin was there, his tone a little anxious.

"If you're free, will we contact online or meet offline?" Xu Yuan said no problem.

Being able to make Hu Yimin find him a layman in such a hurry shows that Hu Yimin is really in trouble, and now he is trying his luck with the mentality of treating a dead horse as a live horse doctor.

Tricky cases, unsolved unsolved cases, each of which will put a lot of pressure on the authorities.

The crime solving rate is one of the hard indicators of whether they are excellent.

In particular, homicide cases are said to be solved in China.

It can be seen how much attention the government attaches to this aspect.

"It's online, it's not convenient offline, it's rare for you to run to us. Hu Yimin said.

Soon, through the laptop video, Xu Yuan learned about the situation over there.

It's not a small case.

A family of four, two husbands and wives, and two children were killed in their home, which was an extremely heinous burglary and homicide case.

Such serious cases are generally time-limited and must be solved quickly in order to ensure social stability.

Otherwise, a vicious murderer is on the run, and it will bring panic to everyone.

But it happened to be an old community, and the layout of various monitoring equipment was imperfect, and it was in a blind spot for monitoring. Hu Yimin: They have been investigating for a long time, but there are no effective clues.

Even, the other party didn't even leave a trace.

It's just so bizarre.

After listening to the analysis of the case, Xu Yuan fell silent.

He is a martial arts person, and he knows many methods that ordinary people can't imagine, if the murderer is a martial arts person, then it is possible that the official can't find clues.

"What about the discoveries on the spot? "If it is a person in the martial arts who committed the crime, I am afraid that Xu Yuan can only recommend Zheng Jiuyuan to Hu Yimin and let the Zheng family help.

"Apart from the broken locks and open windows, no clues were left. Hu Yimin smiled bitterly, in fact, even the two he said were not valid information.

Door locks and windows can only prove that someone has burglied and robbed.

This is also evidenced by the lost belongings.

"Here's a picture of the scene, take a look. Hu Yimin sent the photo to Xu Yuan, and his face was already a little depressed.

You can't see anything from these photos.

What he needs is Xu Yuan's case-solving thinking, pointing out points to him that he hasn't thought of yet.

But if you want to talk about the ability to detect and catch clues from the scene, Xu Yuan is not a professional after all, I'm afraid ......

"It's not like a burglary!"

Xu Yuan spoke.

"What do you mean, what have you discovered?" Hu Yimin subconsciously stood up.

No, just a few photos.

Do you want it to really smell once?

"Look at these photos, the third, fourth, and fifth, things are very scattered, aren't they?" Xu Yuan called up a few photos and said, "But these places will definitely not be places that ordinary thieves will search." ”

"Bedside tables, desk cabinets, underneath mattresses, toilet tanks, toilet vents, etc., are often good places to hide money and belongings. And these places in the photo are not public places at all. ”

"This bandit is either not professional at all and does not know where to start searching for property. If this is the case, it means that he is a novice or an impromptu idea. ”

"Either that, or they know the inside story of the family's belongings, that is, ...... Acquaintances commit crimes. ”

Xu Yuan finished speaking.

Hu Yimin's hair exploded.

These two analyses were something they had never thought of.

It is indeed a new direction of detection.

But from these three photos, can you deduce this?

Not scientific, right?

And this can't convince the public.

You know, this case is time-limited. Hu Yimin proposed the direction of detection, and once it passed, then he would be responsible for the detection. If the last time has passed, and there is no breakthrough in the case, he is in trouble.

For the sake of a case, it is very irrational to put your own future on the line.

Unless there is more sufficient evidence, Hu Yimin will not be able to convince himself to take this risk.

"Is there a photo of the door lock?" Xu Yuan continued.

"Here, right now, but the lock has been broken, and there are only a few clues that can be obtained. Hu Yimin immediately sent another set of photos.

"Where's the key?" Xu Yuan frowned.

"What's the use of the key?" said Hu Yimin, but immediately instructed his subordinates to collect evidence, and then sent a photo of the key.

"Sure enough. Xu Yuan spoke.

He then sent his conclusions to Hu Yimin.

After seeing Xu Yuan's conclusion, Hu Yimin was a little skeptical.

Because Xu Yuan really calculated a new direction.

No, it cannot be said that it is extrapolated, but that it is certain.

The odds are quite high.

"The key to the door, there are traces of being copied. Although the lock of the gate was destroyed, it was not a destructive opening, but a deliberate sabotage, creating the illusion that criminals had broken into the door. ”

"Every time the key is opened, it causes irreparable damage to the cylinder, that is, it leaves traces that belong to the key. At present, the technology and equipment for dispensing keys on the market are not 100% replica. ”

"So the traces left by the replica version of the key to open the door are different from the traces left by the original key to open the door. Later, when you have time, your laboratory can do an experiment and come to a similar conclusion. ”

"So, actually, the door was opened with a duplicate key!"

"And those who have the key to the replica version, I think, should have a good relationship with this family, at least they are familiar with each other, and even, it is not ruled out that relatives and friends committed the crime. ”

"The master with the key near the community, you can ask. The duplicate key, with some mistakes, should be found to the master to refine-tune, when the master modified, most of the impression. ”

"Also, check the family's relatives and friends to see if there are any who can't be contacted. ”

After Xu Yuan finished speaking, Hu Yimin's mobile phone had already been turned on, and he said to the phone: "Did you hear it, immediately divide into two ways and determine the situation as soon as possible!"

A reply came from the other end of the line.

Then Hu Yimin looked at Xu Yuan and bowed.

"Thank you for the new ideas and chain of evidence, let's do it right away. If that's the case, I think we can comfort the souls of the dead in heaven. ”

Xu Yuan nodded.

That night, Hu Yimin sent a message!

"Xu Yuan, you are a god!"

PS: I would like to recommend my friend's new book "I Can See Your College Entrance Examination Score", he is pushing it up, I hope you will collect it more and support it. From the title, introduction to the text of this book, I don't like it, so I recommend it for wall cracking!
