Today is the fifth day of Feng Yuhan's disappearance, her mobile phone is turned off, and there is no news so far, no one knows where she has gone, and even the surveillance of the school dormitory building has not found her shadow.

She evaporated from the world like this. And before she evaporated from the world, she packed all her luggage.

A big living person just disappeared? As I've said a long time ago, disappearances like this are sometimes harder to solve than homicides, because we don't have any clues.

The bottom line is, I'm on fire in my backyard right now!

Li Mengxia doesn't know what's wrong, from yesterday to now, she has always treated me with a nose that is not a nose and eyes that is not an eye, and she always speaks with the smell of gunpowder, and I can't wash it now when I really jump into the Yellow River.

But the good news is that the appearance of Nuo Nuo gave Li Meng a sense of crisis, and she began to be jealous.

Alas, it's all my charm that has nowhere to put it.

Without further ado, we are going to go to Feng Yuhan's bedroom 510 today to conduct a thorough on-site investigation, because the last time we saw Feng Yuhan in the surveillance was four days ago in the afternoon, when she walked into the dormitory.

The technical team is led by Jiang Tingbai, who holds a multi-functional on-site investigation box in their hands, and there is a device similar to a flashlight in the box, which is called "Biological Sample Discovery Instrument", which can be divided into violet light, blue light and white light according to different wavelengths, and can show fluorescence by using specific wavelengths of light on different biological samples.

It is most commonly used to search for biological samples such as blood stains, blood fingerprints, and saliva spots at the crime scene.

The 510 dormitory is a double dormitory, the room is not big, and there are not too many dead corners, Feng Yuhan's luggage is packed very neatly, and it seems that he will leave the school in a few days. And He Peining took a break from school, and he had already brought everything home a month ago.

After the technical team used the biological material discovery device to illuminate the room with lights of various wavelengths, Jiang Tingbai suddenly found a large number of marks on the bed next to the door. These marks are colorless, and after volatilization, they are not visible to the naked eye at all, but they cannot escape the professional instruments and equipment in the hands of our technicians.

"What kind of mark is this?" I asked hurriedly.

Jiang Tingbai took a closer look, this mark appeared on the sheet, after different wavelengths of irradiation, he raised his head to look at me, and said lightly: "This is a sperm spot, and there is a small amount of blood." ”

Sperm spots?! A small amount of blood?!

I was stunned, this is a girls' dormitory! How could such a thing come about? Could it be that a man has ever come into this room?

The sperm spot was found on the bed next to the door, and this bed belonged to He Peining.

He Peining brought the man into his dormitory, and the Wushan clouds and rain happened on his bed? And also gave him his precious first time?

Is He Peining so crazy? Now that the inns outside are not expensive and more private, why would she bring men into her bedroom?

It's really crazy.

I can't find any other suitable adjective than this sentence now.

After our investigation, we found that He Peining's reputation is very bad, many people say that her private life is very messy, she likes to smoke, drink and jump, often goes out to eat, drink and have fun with a large group of men and women, and sometimes she stays up all night. I really didn't expect that she would be as guarded as a jade all along.

But the more this happened, the more crazy it became that she brought the man back to her bedroom.

At this moment, I suddenly understood one thing, that is, why He Peining suddenly suspended her studies a month ago, and the dean of education did not mention the reason for her suspension. I also understood why the school's dormitory was suddenly strictly managed after He Peining took a suspension.

Because He Peining brought the man into the dormitory, this matter was discovered by everyone and the school, even if He Peining's reputation is not good, but a girl doing this kind of thing in her own dormitory probably has no face to continue living here.

So she chose to suspend her studies, and the reason for her suspension was even more difficult to say, and it was even more difficult for the dean to speak, so when we asked the teacher why Pei Ning was suspended, she would be hesitant and prevaricate.

It is precisely because of this incident that the school is ready to strictly manage the dormitory in order to prevent similar things from happening again, but the students, who have long been accustomed to the loose dormitory life, are very opposed to the school's sudden strict management, and then there will be conflicts with the school and the students.

In the end, the so-called strict management will exist in name only. So when I came to the dormitory yesterday to investigate, even though the doorman saw me, she didn't ask, let alone stop me, and let me walk into the girls' dormitory building as a man.

This is a very plausible explanation, and I believe, it is the only one.

But He Peining did this kind of thing in dormitory 510, as Feng Yuhan, who also lives in dormitory 510, how would he react? Could her disappearance have something to do with it?

Just when I had already begun to think about the next question, Jiang Tingbai seemed to have insight into my psychology.

He thought for a while, and suddenly said to me: "Why are you sure that the sperm spots found on He Peining's bed are related to He Peining?" Wouldn't it be someone else who walked into this bedroom, in He Peining's bed? Or, is this person Feng Yuhan? ”

What Jiang Tingbai said was very reasonable, and I actually ignored such an important direction of thinking.

It seems that if I want to solve this missing person case, I first need to calm down.

Technicians have extracted sperm spots and blood from the sheets and are ready to take them back for DNA testing. At the same time, the technician took away one of Feng Yuhan's toothbrushes, preparing to extract DNA from the toothbrush and compare it to confirm whether the blood on the bed sheet came from her.

Although we don't know what the result will be yet, we still have a lot to gain from coming to the 510 dormitory to do a thorough investigation. Technicians then recovered some fingerprints and footprints at the scene, but nothing else.

This is a girls' dormitory, a place where students live, and we have to do our best to investigate the site carefully, and save a second time. The technicians not only surveyed the site, but also took pictures and recorded everything on the site.

Next, all we have to do is wait for the results of the DNA comparison.

When I returned to the office of the Serious Crime Team, I suddenly found that Li Meng was gone.

"Where did Li Meng go?" I asked Lin Zifan.

Lin Zifan shrugged his shoulders at me and said, "She took Nuo Nuo to go shopping." ”
