Qin Yongmei was still a little hesitant.

Bai Ce persuaded on the side: "Bai Ke is already an adult, so he should be fine." ”

Qin Yongmei picked up the dossier: "Try to ignore some bloody photos." ”

Now, the police have begun to use color photos.

The scene of the crime became particularly thrilling.

In fact, white customers don't want to look at those things.

After all, Wen Jin once stood alive in front of him.

But in order to understand the details of the case, he could not ignore these things.

Seeing the bloody scene, Bai Ke realized that he had overestimated his endurance.

Ju Wenjin, who was once lively and lovely, was like an animal that had been slaughtered.

She was completely enveloped in crimson blood.

He was stabbed more than 20 times all over his body.

Except for a shallow knife in the back, the rest were stabbed in front of him.

A living life was gone.

Bai Ke couldn't help but shed tears.

Qin Yongmei stretched out her hand to take away the photo, but Bai Ke hurriedly stopped her.

Choked up and reasoned: "The knife technique is messy, the criminal should be a first-time offender, and he doesn't even have experience in slaughtering animals." ”

Qin Yongmei nodded: "The analysis makes sense." ”

"Wen Jin must have resisted violently before his death. The situation at that time should have been like this: the criminal pressed a knife against Wen Jin's waist and wanted to force her to go to the grass next to her to insult her. But it was strongly resisted by Wenjin. ”

"Well, go on. ”

"It follows from this that the offender is not only a first-time murderer, but also not strong. Because Wen Jin is just a girl with a height of 1.6 meters. Judging from the scene, it is possible that the criminal was scratched by Wen Jin......"

"Well, the more you say it, the more correct it becomes. Wen Jin's nails did find flesh and skin tissue. It should have been left behind by criminals. ”

Bai Ke still sighed: "It's a pity that our current technology can only check the blood type." ”

"And what else do you want to find out?"

"But it's not enough to have a blood type, it's just a quarter of the scope of the investigation. ”

"There are still scars, and there are footprints, which add up to not be small. ”

"yes, but you can't always search the whole county. ”

"Of course, let's do a small search first. Tell me which range is better to start with?"

"Mom, have you ever heard of the mental comfort zone?"

"What kind of criminal investigation theory is it in the United States, right?"

This means that a first-time offender will commit a crime within a range that he considers safe. ”

Qin Yongmei scoffed: "We have already discovered this problem. An investigation must be launched around the crime scene first. Because the criminal was stained with blood, if he was far away from home, he would have been discovered. ”

"But this range is still not small......

"Yes, if the offender is a college entrance examination student, we may only have two months. ”

"And the city bureau doesn't let the investigation go into a big show. ”

Qin Yongmei smiled: "You know this." ”

Bai Ce frowned: "If such a big case happens, what can be found out by quietly investigating?"

Qin Yongmei sighed: "In order to stabilize and unite, in order not to affect the review of college entrance examination candidates." ”

"How is the age range defined?"

"Between fifteen and thirty-five, of course. Pay special attention to college entrance examination candidates. ”

"And it doesn't have to be a man. ”

"Oh, the criminal's footprint is a 40's pull-back sneaker. ”

"It's so common that half of all middle school students have it. And there are not a few girls who wear 40 shoes. My third sister Fengqin wears 40 shoes at one meter and six meters. ”

Qin Yongmei sighed: "Let's exclude women for the time being, otherwise the scope will be too big." The key is to look at the scratch marks. ”

"It's summer, and the scratch may be exposed, or it may be under the clothes. If the latter were to be found, it would be difficult to spot. ”

"Yes, our police force is simply not enough, so we can only ask the streets to assist, door-to-door investigation. ”

Bai Ke sighed: "If the criminal escapes this time, he will not be able to commit another crime in the future." ”

Qin Yongmei frowned: "Don't say such frustrating words, if our public security officers are all like you, how can we solve the case?"

In fact, Qin Yongmei has already encountered a serial murder case.

That is the Beidahe serial homicide case.

It's just that the criminals disappeared after killing three people in a row.

And Qin Yongmei and they didn't find any new clues.

**************************

The public security has really done a good job of keeping secrets.

Just like in the previous life, the vast majority of people did not know that Ju Wenjin was killed.

It seems that Ju Wenjin has never been to this world.

Bai Ke couldn't help but feel sad.

If the criminals are not caught early, not only will more people suffer in the future.

Wen Jin is also equivalent to dying in vain.

There is a risk that the capital chain will be broken, and a serial killer will suddenly appear.

These have caused a lot of distraction and a lot of time for white customers.

The review was not fully developed.

In two consecutive exams, Bai Ke's results fell outside the top 50 in the whole grade.

The whole class was also ranked around ten.

This achievement is not to mention Tsinghua University and Peking University.

The key universities are a bit in suspense.

Sun Yuan also came over to comfort Bai Ke: "Don't worry, can you bet on the question again?"

Bai Ke smiled bitterly: "There is still a week left, can it be in time?"

"Try your best, it's a big deal to get into an ordinary university, just go to Kyoto, anyway, I'm a proper Qinghua. We're always in the same city. ”

"Cut, you're so confident?"

"It has to be dropped. ”

However, if you can be admitted to a major university, the probability of getting into Kyoto is greater.

If you are admitted to an ordinary university, the probability is much smaller.

This is because there are many fewer general universities in Kyoto than in major universities.

However, the white customer actually doesn't care about this.

Because from the day he met Ju Yinglun, Bai Ke had an amazing decision.

But, whatever that decision is.

Bai Ke has to complete the most perfect college entrance examination in this life no matter what.

There are three or four days left.

Many of my classmates have gone home.

For the sake of today, it's even more important to stay in top shape.

Bai Ke also wanted to sleep for three days before getting up and walking into the examination room.

But I was still unwilling to read and review books day and night.

Parents don't come to persuade Bai Ke to go to bed early.

Anyway, this is the last moment of the first battle in life.

Bai Ke was sleepy in the middle of the night, and fell asleep on the desk.

In the dream, Tang Tower, who had not been seen for a long time, reappeared.

You bastard! Lao Tzu, who almost killed him, became a criminal suspect.

I don't blame you for wronging me for so many years, do I?

Wronged you, although you are not a serial killer, and you have done less bad things?

Hehe, the girl is not less.

If you want to be beautiful, you won't want to sneak out in the future.

I have to come out, or who's going to help you?

You help me? I'm going to take exams and I'm not fighting.

I'll go, I'll be of no use for anything but fighting?

What do you think?

Alas, it hurts my self-esteem, and it seems that I don't need to tell you that half.

That's half?

What do you say? Remember to promise Bobo.

Bai Ke suddenly woke up.

As someone who has experienced the college entrance examination in his previous life, those thrilling days must be deeply imprinted in his mind.

White customers should remember all the college entrance examination questions.

But he only remembered half of it.

Could it be that Tang Ta can remember the other half?

The possibility exists.

There are only two days left, and it is time to give it a try.

Bai Ke took out a small mirror.
