Mu Yuan borrowed the digital certificate from the office Xiao Chen, signed the borrowing registration book, and then returned to his office and began to search for cases.

For the choice of the case, Mu Yuan had already planned.

He knew that his greatest strength was his sense of smell, which was sharper than that of a hound.

Therefore, there must be a residual breath at the scene of the crime, and cases such as telecom fraud do not need to be considered. At the same time, the time of the crime should not be too long from now, and it is better to take the case within one day.

Based on the fact that he was the wool of someone else's house, he could not return to the scene of the crime as a police officer handling the case, so the case where the crime occurred was a private place was excluded.

After some searching, there were more than 100 cases in front of Mu Yuan's eyes.

"Theft, stealing a computer, small case, too!"

"It's theft again, Nima, are there so many thieves? You just steal a mobile phone, and you're embarrassed to do it. ”

"This one is kind of interesting, stealing ten chickens. Why don't the chickens crow? I can't afford to provoke them. ”

After some searching, Mu Yuan found that most of the cases were not suitable for starting, either the severity was not enough, or it was too difficult to detect.

Suddenly, Mu Yuan's expression moved, and he found an interesting case.

This is a case of intentional wounding.

Generally speaking, this kind of intentional wounding case is very simple to solve, because there must be a certain amount of grievance between the suspect and the victim, and the victim generally knows the suspect.

As long as the injured person is not dead, it is not too simple to find the suspect.

But in the case in front of him, the victim didn't even see who the suspect was, and was knocked unconscious with a stick.

And then the hands and feet were broken - well, not completely severed, of course, but broken bones.

By the time the victim woke up, he was already on his way to the hospital.

At that time, he must have thought in his mind: Who am I, where am I, what did I do?—— no, what should I have been done?

As for who knocked the stick, who knows?

The crime took place at night and there were no witnesses around.

And this is obviously a premeditated case, as long as the suspect has no problem with his brain, he will not choose to act under surveillance, and it is basically impossible to directly lock the suspect.

This case also belongs to the Huacheng District Bureau, but it is not under the jurisdiction of the Qinglong Street Police Station, but the West Street Police Station.

The area under the jurisdiction of the Qinglong Street Police Station is mostly a commercial area and a well-formed residential area, and the public security situation is very good, and the incidence rate of criminal cases is relatively low.

However, part of the area under the jurisdiction of the Xijie Police Station belongs to the suburbs, that is, the urban-rural junction, and the public order chaos is prominent.

Of course, this also has a great advantage, after being abused thousands of times by various cases, the leaders of the whole firm finally point a skill to MAX, and this skill is case transfer.

Take the case in front of you as an example, intentional injury causing serious injury is a proper big case, and it naturally needs the masters of the criminal investigation front to show their strengths.

Uncle will always be your uncle, not only are the serious cases they have solved not comparable to the police station, but the number of unsolved major cases also crushes the police station.

In other words, it is a police station, with an important case on the door of the head that has not been solved, and the leaders of the sub-bureau absolutely call over every day to "care and condole", and even the main leaders of the bureau occasionally summon the leaders to the office to express their ardent hopes.

However, the criminal law is different, and how many unsolved serious cases are there at the criminal college? Can the leaders be concerned? Not to mention that it is just a kind of person who has broken his limbs, even if he has broken his limbs, there are all unsolved ones, and this is very normal.

There are more lice and there are no worries, and the criminal investigation brigade doesn't care about more such unsolved cases - of course, it is best to be able to solve them.

The time of this case was in the early hours of this morning, and the leaders of the West Street Police Station responded sharply, and after rushing to the scene and seeing the scene when the victim was carried into the ambulance, he immediately contacted the criminal investigation team to pick up the pot...... Uh, take over.

The response of the criminal investigation brigade is also quite fast, and in just a few hours since the case occurred, the case has been accepted, the case has been filed, and the witness records have all been made and transmitted to the Internet.

What Mu Yuan could learn was only the information that came up.

Through analysis, the Criminal University should not have figured out the clue at present-it cannot be ruled out that the police handling the case have clues, but they are not reflected in the records or legal documents.

But come to think of it, in such a case, there is really no need to hide clues or anything.

After all, under normal circumstances, in addition to the investigators in charge of the case, only the leaders of the legal department and bureau can see the specific content of the case, and the possibility of leaking police secrets is extremely low.

There was no surveillance at the scene of the crime, which is also normal.

That place belongs to a shantytown, which can be demolished at any time, and countless local tyrants are born, which local tyrant wants to be exposed to surveillance at any time?

Uh-well,, the main reason there is no monitoring here is indeed because of the imminent demolition, but not to take care of the emotions of the future tyrants, but there is no need to waste resources.

It's just that now that this case has happened, the difficulty of the investigation has undoubtedly increased a lot.

This is also normal, the level of informatization has been getting higher and higher in recent years, and the slogan of public security to science and technology for police force has been blowing for more than ten years, and the coverage rate of monitoring probes is getting higher and higher.

This is a good thing, and it makes it much easier for the police to solve the case.

But this is also a double-edged sword, it makes the police group gradually increase their dependence on surveillance, and many police officers will not be able to handle cases after leaving the surveillance.

Mu Yuan looked at this case, but his eyes were shining.

It's just been a few hours since the case, and your nose should still be useful, right?

......

Huacheng District Bureau, Criminal Investigation Building.

Cheng Bin, deputy captain of the Criminal University, is in charge of the third and fourth squadrons.

These two squadrons are responsible for infringement cases, and the third squadron is responsible for major infringement cases, such as cases of serious injury or above, intentional injury, rape cases, etc. The 4th Squadron is responsible for cases such as minor injuries.

Of course, the distinction here is actually not so strict, for example, the previous indecent case, if it was strictly distinguished, it should belong to the case of the Third Squadron, but because the pressure from above was too great, it was the elite force of the entire criminal university to do it.

Even if Cheng Bin is the deputy captain in charge of infringement cases, he is also a brick in the previous indecent cases.

After all, the deputy director is in charge, and he, the deputy captain, is only a small soldier.

Therefore, he didn't have much feeling about the fact that the case was later broken by the Qinglong Street Police Station.

On the one hand, because he is not the main investigator of this case, on the other hand, he also has a heart to be a salted fish.

In fact, most of the policemen have the heart to be a salted fish, but they don't have the life of a salted fish, which Cheng Bin feels a lot.

For example, now, this team has a lot of headaches.

"There's not a single surveillance surveillance, even if it's the analog camera from a few years ago?" Cheng Bin touched his somewhat dangerous hairline, and his tone was depressed.

Four policemen sat around him, each innocently staring at the leader's helpless face.

No monitoring is no monitoring, can it still be changed?

Wang Ziyu sat on the right hand side of Vice Captain Cheng, shook his head, and said, "Brother Cheng, that black light is blind, even if there is an analog camera, it is a fart?"

"Yes. Cheng Bin pinched his temples, "Did the technical detective ask over there, can you give me some support?"

"It's useless, unless we can fully lock down the suspect's line of movement. ”

Cheng Bin's face was not very good-looking, and he vomited: "! If I can lock the suspect's course of action, do I still need their help? ”

Wang Ziyu: "(╯⊙⊱⊙╰)"

Just listen to this, it's impossible to answer the phone, if it reaches the ears of those uncles of technical detectives, it will offend people ruthlessly, what will happen to the case in the future?

"At present, the only clues we have are those stated by the informant, which are not of much value to solve the case. Wang Ziyu said: "However, judging from the modus operandi, the suspect must have a certain grudge with the victim." ”

"Aren't you talking nonsense?" Cheng Bin said, "The victim has a lot of money, and he didn't pick up the mobile phone when he dropped it, plus the practice of breaking his limbs after knocking him unconscious, a fool can see that this is a conscious revenge." But the key is that according to what we learned from his family and colleagues, the victim was a good gentleman, and he had never offended anyone on weekdays, and he couldn't even find a suspect object. Forget it, I guess the victim should be awake soon, you go to the hospital, and ask him directly when he wakes up. If he doesn't offend anyone, he should know best. If you can't break it, there's no way to do it. ”

Wang Ziyu nodded, although the last sentence made Wang Ziyu a little helpless, he was also helpless when he met such a policeman who liked to be a salted fish. But he also had to admit that there were indeed very few investigative methods they could use at present. It would be great if you could get clues directly from the victims.
