The training of the special training center is originally a high-pressure training mode, not only to train the physical fitness of these trainees, but also to add some special courses, computer is one of them.

Although this thing has not been in China for a long time, the leaders above are still keenly aware that this thing has a high demand for future work.

Maybe in the future work, these devices will be gradually introduced into the middle of the work, and when the time comes, it will take too much time to find someone to learn these things, so it is better to ask people to start adapting to it now.

After the equipment is introduced, they can get started at the first time, which is undoubtedly a good thing for the future work progress.

It's just that more than half of the personnel trained this time are veteran police officers, and they are far inferior to these young police officers in terms of thinking and adaptability.

But these veteran police officers are the foundation of the police force, and the newcomers are always the blood of the whole force.

A community needs to have new blood coming in, and it also needs to have roots as a kind of inheritance.

This kind of training method, in terms of academics, uses newcomers to lead the elderly, and in terms of detection experience, there are old people leading newcomers, and in the shortest time, these people are run-in into a group, integrating their advantages, and learning from each other's strengths, which is naturally the most time-saving way.

As for Ding Fan's arrival, to be honest, the above teachers are a little at a loss.

Especially the chief teacher, who has been a police officer for many years, what he has heard the most is Ding Fan's deeds in the Northeast back then, and it can be said that he has listened to various legends along the way to today.

He has too much admiration for this police legend.

But now his identity has become a fact, he is the instructor here, and Ding Fan is the student here.

Let him teach Ding Fan now, to be honest, he doesn't know how to teach.

The foreign languages, computers, and driving skills that the students need to learn are all leftovers from Ding Fan's play.

Ding Fan successfully passed the assessment seven or eight years ago, and then stayed abroad for eight years, and his foreign language level far surpassed that of them.

As for the computer, although I don't know if Ding Fan will be able to, but at least this thing seems to have been in use overseas for a while, and even the chief instructor himself doesn't believe it.

As for the driving skills, it seems that Ding Fan learned earlier than anyone else, and he has heard of it a long time ago, when he was still in the Northeast, he often drove a modified car all over the street, and when it came to driving time, it seemed that no one could compare with them.

As for crime analysis, it seems that Ding Fan has been studying this thing a few years ago, although I don't know what the result is, but at least in this regard, he is ahead of everyone.

Calling such a person to come over to study, I really don't know what the leaders above think, it's almost the same to call him over as a teacher?

Isn't this specifically called to embarrass the instructors?

When I met a student who had nothing to teach, to be honest, they were also a bit of a headache for these instructors.

Teaching normally, it seems that everyone is better than themselves in everything, and what they say is simply a joke in their ears, and if they can't get off the stage when the time comes, even if the faces of these instructors are thrown out, they don't have to think about the next courses.

But say no!

It seems that they violated the task assigned to them by the leaders above, and they fell into a dilemma at once.

In desperation, the chief instructor had no choice but to pick up the phone and call Minister Lei, who was directly in charge of this matter, hoping that there would be some solution to this matter.

But after listening to the phone, Mr. Lei just laughed, saying that this was also an exam question for these instructors, and it was a test for them, and the way was to ask him to think for himself.

The only hint is that Ding Fan is not given to them for training, but to give them a whetstone, and it is up to them to use it.

When the chief instructor heard this, it was like an initiation, and he immediately understood what Mr. Lei meant.

The exam three days later was held as scheduled, although Ding Fan was the last to report it, but he still had to take this exam, and he had to record the credits, and the credit system would be exactly the same as everyone else's, and there was no discount at all.

The exam is not difficult for him, this kind of computer, when he was abroad, he has used it I don't know how many times, in order to learn this thing, he paid a lot of price.

When he was abroad, there were special people in the camp who were in charge of this thing, and when he was fine, he would send some cigarettes and alcohol and other things, and he learned a lot from the hands of those people, although he was not as good as those professional people, but compared with these instructors in front of him, his proficiency was even better.

The final exam result, there was no suspense, Ding Fan won the highest score, which no one had ever thought of.

Only these instructors understood that Ding Fan coped with this kind of exam as if he was going home for dinner.

After the exam, all the team members could have rested for a few days, but because of Ding Fan's high scores, all the team members had to practice for a week.

This week's time was originally a holiday time, and now the only person who can take a holiday and rest is Ding Fan alone.

This made all the people who participated in this training have a strong resentment towards this person named Ding Fan, if it weren't for him, everyone would be able to take a vacation and rest now.

Now, everyone is practicing, and the only person who can rest is him.

Of course, this atmosphere of resentment only lasted less than three days, and the headquarters suddenly received news that someone reported a case in an old town in the south of the city, saying that there was a strong smell of corpses in the sewers, and after the police arrived at the scene, they found half a corpse in the sewers.

The situation was serious, and the chief instructor took over the case and rushed directly to the scene with hundreds of trainees from the training center.

At least a dozen of these people were forensic professionals, cleaning up the scene and making forensic reports.

It was preliminarily determined that the deceased was a male, and the time of death was about three days, and the victim was pierced through the abdomen with a sharp object, and the death was caused by excessive blood loss.

All the trainees were immediately divided into groups, analyzed the case this time, and made a report two hours later.

Just when these team members were still analyzing all the clues of this homicide, a murder occurred again in an abandoned two-story building in the south of the city, and the training center had to divide the people in their hands into two groups to investigate.

And this time the case is even more puzzling, it looks like a closed room murder case.

The deceased fell at the door of the room, the doors and windows around him were closed, there was no trace left by the murderer, there was no trace of the doors and windows being pried open, and the only vent in the room was a skylight airway about two meters and a half from the ground, but this airway could not accommodate an adult to drill out, unless the murderer was just a child about eight years old.

But the deceased was an adult, weighing 80 kilograms after testing, and a child about eight years old had no way to tie up the adult and kill him in a closed room carried to the second floor.

It is even more impossible to climb that blowhole with bare hands.

At this time, all the students were stunned

, looking at this confined space, I can't think of a reasonable way to kill people at all.

Not to mention them, even the instructor who led the team this time couldn't figure out how the murderer killed people and then left the scene.

Many people at the scene suspected that the deceased committed suicide, because there was no way in this room to leave the scene after the killing, and there was no other possibility than suicide.

"Actually, in this world, there has never been a perfect secret room killing, I have seen many cases of closed room murder in books before, and the final result is the same, that is, this secret room is not completely strict at all, and there is always a more or less way to let the murderer leave. ”

Everyone was still watching the scene, as if they wanted to find out the key points in this room, proving that this was not a complete secret room, except for a policewoman, squatting at the place where the corpse had fallen, carefully grasping the matter, and finally looking at the airway directly above their heads.

And her analysis made the instructors around her agree very much.

If Ding Fan was on the scene now, he would definitely recognize this person, because these two people were old acquaintances.

"When I entered the door, I saw the door lock, the door lock is the inner anti-lock structure, in fact, it is not complicated at all, as long as the handrail is lifted up, the door lock can be completely locked, and the door is opened by pressing down, and this door lock is a little different from other door locks in the room, it should be a new lock, but it is not brand new, it should be a second-hand goods, it is the murderer in order to complete this secret room, deliberately replaced, as long as the rope comes in from the airway, fixed on the handle of the door lock, pull it up, the door lock will be locked, and the whole secret room will be easily completed。 ”

The policewoman's face confidently analyzed everything in this secret room, and she gently wiped it on the doorknob, and a little fine fiber residue was stuck on the white gloves.

"This should be cotton wool, could it be that the murderer cleaned up the traces on it?"

A tall and handsome police officer stood beside the policewoman, carefully checking the residue on the top of the gloves, and also checked the underside of the door lock.

"No, but the murderer put a layer of cotton cloth on the door lock, after the rope is tightened, as long as he pulls the rope tightly, the cotton cloth will slip off the handle, except for a little cotton wool residue on it, nothing will be left, and even the handle will not have traces of strangulation, this murderer is very cunning. ”

After some analysis, the surrounding students were attracted by the policewoman's words, and kept nodding, feeling that her analysis was very reasonable, but some of them felt that his analysis seemed to be a bit of a loophole.

"Let's look at the location of the body on the ground, the position of the deceased's head facing the door, at this distance, once the deceased falls to the ground, it is obvious that the door cannot be opened, and there is no trace of physical movement on the ground, but if the victim is not dead before the murderer leaves, then how was he killed?"

"Could it be that the victim wanted to climb out and call for help, but because the injuries on his body were too serious, he finally died of exhaustion at the door, and accidentally died at the door?"

"No way, there is no trace of dragging on the ground, and the deceased was strangled to death, and the ropes on his body were not untied when he died, so it was impossible to climb out at all. ”

A group of students kept arguing with each other for this case, trying to overturn the other party's judgment, but in the end, anyone's judgment seemed to be a little lacking, only the policewoman was the most calm, constantly looking for the remaining clues in the room.

"Anyway, the lock on this door is likely to be a breakthrough in this case, as long as we find the person who bought the lock, there should be new clues, such a door lock is not used much in the city, and it is second-hand, it should not be difficult to find this person. ”
