Solving the case: Combining the police dog's olfactory genes at the beginning

I saw a girl about 20 years old lying in a pool of blood.

The face is no longer recognizable.

But there were still a few bloody footprints on the ground.

The security guards also realized it.

This is most likely a clue left by the murderer inadvertently.

So to ensure that the scene will not be destroyed.

He immediately contacted his superiors.

The classroom was also sealed off.

To prevent the site from being damaged
But hear this.

Luo Fei had doubts.

"Mr. Security, from what you said, you are not the only one who has the key to this classroom."

I heard the other party ask this.

The security guard also did not comment.

"Yes, officer. Because our school has many graduate students, they occasionally come to this classroom to rehearse in advance. Sometimes, graduate tutors will also ask us for spare keys and come to the classroom to prepare in advance."

Hear this.

Luo Fei also nodded.

"If that's the case, then the person who asked you for the key yesterday and rented the classroom to use today is a big suspect."

Luo Fei also took a look at the footprint next to the girl's body.

"In addition, judging from the size of the footprint, the murderer should be a girl of the same age as the deceased."

"That should be the deceased's classmate, or someone who was close to him."

Just as they were talking.

A boy has arrived at the scene.

He kept muttering to himself.

"No, officer, I really didn't do this."

"I can assure you that I really never intended to harm anyone."

The boy looks tall and thin.

Although he looks ordinary, he gives people a scholarly feeling because of a pair of glasses.

But I saw that he was very scared.

Luo Fei also asked.

"From what you said, it seems that you knew the deceased?"

Hearing the other party's tone.

A little surprised.

The man did not comment.

"Yes, officer."

"I guess the deceased is most likely one of my girlfriends."

But after hearing these words, even Lao Han and the others looked at each other.

"How many girlfriends did you say you had?"

obviously.

The young man's words made everyone else a little confused.

And he remained noncommittal.

"Officer, to be honest with you, I haven't thought about dating before because I'm still in school and want to focus on my studies."

"But these two girls approached me one after another and said they wouldn't mind being my girlfriend at the same time."

"But I don't want to agree to it. After all, if this kind of news gets out, people will say that I have a problem with my lifestyle."

But as time goes by.

These two men pursued him relentlessly.

And she is very considerate to boys.

Plus, they seemed to be pretty good friends, so the boy agreed.

Just heard the news

Old Han at the side also twitched his mouth.

“It’s really hard to understand young people nowadays.”

Luo Fei asked.

"You said there were two girls?"

"So are these two your only girlfriends? Or is there someone else? But we, the police, don't know?"

I heard the other party ask this.

The boy didn't comment.

"Actually, I have more than just these two girlfriends."

"There are also some suitors who secretly gave me gifts."

But because the two of them are more united in facing the outside world.

So all the girls were driven away by them.

only.

I heard the other party analyze it this way.

Luo Fei couldn't help but frown.

"These two people probably want to possess you, so they drove the others away."

"But when there is no external threat, they become each other's enemies. After all, although they talked well at the beginning, they may have their own ulterior motives and no one is willing to be your only subordinate.

Hearing this analysis.

The boy also said.

"Officer, this is none of my business. I didn't expect that they appear to be good sisters, but actually would do such a thing."

But the other person looked timid.

It was as if he was afraid that he would be held responsible.

Luo Fei also acted as if nothing had happened.

"You didn't make any mistakes, and you weren't the mastermind in this matter. Why should I hold you responsible?"

Of course Luo Fei knew.

The boy actually understood that what he did was wrong.

The fact that he has multiple girlfriends is enough to show that there are serious problems with his lifestyle.

But from the perspective of this case, it was definitely not him who did it.

So even Luo Fei had some opinions about the young man's behavior.

But that has nothing to do with this case.

at this time.

The deceased's class teacher has arrived here.

"The officer passed by us just now to check the dormitory, and I found that these two people have not returned since they left the dormitory yesterday afternoon."

"I heard from the dorm aunt that they went to the study room first, and it seemed like they were planning to have dinner together as usual."

But then I don’t know what happened.

Perhaps a fierce quarrel had occurred, leading to such a tragedy.

Hear the other person say this.

I am worried.

Luo Fei also asked.

"Teacher, you're here just in time. We were actually very curious about the relationship between these two female students. Have they ever had any conflicts?"

"Officer, this is absolutely not the case. The two of them are good sisters and are as close as one person. This is why I was so surprised when this happened."

Just as a few people were talking.

Another security guard.

He ran over here out of breath.

"Team Leader Luo, we have just discovered the whereabouts of that girl."

Just as he spoke.

The other two boys had already brought the girl to the office.

But the other person looks thin and weak.

His face was full of fear.

There was really no way for everyone to associate her with a murderer.

I also saw her lowering her head and keeping silent.

Luo Fei also said.

"Ma'am, tell me, what's going on? Why did you and your friend become enemies?"

But I heard the other party ask this.

The girl said this tremblingly.

"Officer, this is really not my fault."

Seeing each other is very depressed.

Luo Fei also said.

"I can give you a chance to explain what happened, but you'd better tell us the details of this case truthfully. If you deliberately conceal the truth, then we can't show you leniency."

But I heard the other party say this.

The girl felt very aggrieved.

"Officer, this guy is to blame for this. He is the one wavering between the two of us!"

It turned out that just last night, the girl and her best friend had a big fight.

The cause was that neither of them was willing to give in.

Both of them felt that the other party should take the initiative to withdraw from this three-person relationship.

I was also angry at that time.

This girl would do something to hurt others.

I just heard what happened.

Luo Fei couldn't help but frown.

"But even if you were really impulsive at the time, why didn't you call the police immediately after it happened?"

"In addition, our preliminary examination of the body just now revealed that this girl was not only disfigured, but also had corrosive liquid splashed on her face."

"Are you trying to tell us that you did this on impulse?"

Luo Fei thinks so.

At least from a criminal psychology perspective.

This girl would do such a thing to a corpse.

That's enough to explain.

She may have completely broken through her psychological defenses.

It's because everything is broken.

Even to the point of being reckless.

That's why they deliberately vent their inner anger on the corpse.

And when I heard the other party ask this.

The girl was speechless for a moment.

Of course she knows.

anyway.

There is no way to explain what I do using common sense.

He looked at her with her head down, saying nothing.

Luo Fei also said.

"Miss, if you really have a clear conscience, please come with us and cooperate with the investigation."

Hear this.

The girl's face suddenly turned pale, because she knew very well.

He was the only one who did this from beginning to end.

It is also because I want to monopolize this boyfriend.

That's why she did something so extreme.

And that afternoon.

Luo Fei and his team took the girl to the serious crime squad.

He finally couldn't hold it in anymore and spoke out all his inner thoughts.

"Officer, I didn't mean to hurt her at first."

"But no one expected that she would tell me that I was always strong and always quarreled with him. This made her feel very uncomfortable.

, which was also out of resentment towards me. She also cursed at me, saying that it was because I had to argue with her all the time that she became very unhappy. "

"When we were working on a paper together, I would compete with her for the topic, and now I'm competing with her for her boyfriend. This is really intolerable for her."

Also on impulse.

This girl would kick her friend to the ground.

And hit the other person on the head with a stapler.

Knock her out.

It was just because I felt a little unhappy when I thought about what she had just said to me.

The girl's overly strong possessiveness made her make a decision that she would regret for the rest of her life.

She actually took out a highly corrosive liquid from the cabinet in the laboratory in the corner of the classroom.

It fell on the friend's face, which completely disfigured the other person.

And just then.

Deng Wen has also issued an autopsy report.

"Team Leader Luo, based on our investigation just now, we found that the condition of the deceased is indeed consistent with what the girl described. She is telling the truth."

Hear this.

Luo Fei nodded.

Because now the confessions and physical evidence are all available.

Therefore, Luo Fei and his team can basically close the case.

That evening.

Li Yu and the others couldn't help chatting while sitting in the office.

"I really don't know what's so good about this boy. Logically, their academic qualifications should be similar. This girl is just one grade younger than them."

"And their academic performance is better than this boy's. But they are crazy about this man. It's really incomprehensible."

Luo Fei said.

"Sometimes it's not necessarily because the person is so outstanding. Sometimes it may be a kind of comparison mentality, thinking that I should use what others have, and it has to be the best."

"If both of them were not interested in this boy, the tragedy might not have happened."

Luo Fei explained this.

It seems quite reasonable.

After all, sometimes.

The key is not who the target is, but the parties involved want to compete with each other.

Such analysis.

It made Li Yu and the others feel that.

Luo Fei’s summary is very reasonable.

However, this also made Li Yu and the others couldn't help but be amazed.

"The same is true for these two people. If they could be more open-minded and realize that it is not worth it to give so much to this man, then the tragedy might not have happened."

Just as a few people were talking.

An older sister has arrived at the serious crime unit office.

"Officer, this is horrible. I didn't expect this to happen. I want to call the police. I want to call the police now!"

Hear the other person say this.

And his face was full of shock.

It seems like he was greatly stimulated.

Luo Fei had no choice but to comfort her.

"Big sister, please calm down and tell me slowly. What is going on?"

Looking at each other's curious eyes.

The elder sister then hurriedly explained.

"Officer, I was cleaning our hotel just now. And in the corridor, I saw a black luggage bag."

"The young man was struggling to carry the bag, so I offered to help him."

"But he just said he didn't need my help, and I didn't think much about it at the time. I still helped him throw the large bag to the garbage station."

The elder sister was still curious at that time.

What on earth is in this bag?
So I asked the young man what was inside?
But this moment.

The other person avoided my gaze.

"It was only after the young man left that I felt something soft inside the bag. There was blood seeping out."

“That’s when I realized something was wrong.”

At the beginning, the eldest sister still held a glimmer of hope.

It was out of curiosity that I opened the bag a little bit.

Want to see what's inside.

"I didn't expect that when I just opened a corner of the bag, I found a dead body inside. It scared me to death."

When he heard his elder sister say this, his face turned pale.

Luo Fei also said.

"If what you said is correct, this young man is most likely the murderer."

Hear this.

The eldest sister also nodded: "Officer, I think he must be the bad guy!"

"Because I heard from our hotel's front desk staff that this guy was carrying a large suitcase when he first checked into the hotel, and he also asked if he could live here long-term."

"He gave us the impression that he was very panicked."

Hearing the elder sister's analysis.

Luo Fei also nodded.

"Thank you so much for providing the police with the clues. This is really helpful for our follow-up investigation."

Heard the news.

But the eldest sister said.

"Officer, do you think this man is a random criminal? What if he targets the waiters in our hotel?
Now I feel scared just thinking about it.”

I heard that the other party's tone was a little uneasy.

Luo Fei also said.

"Sister, the clues you provided to us have been of great help to our police, but as for the specific situation, we still need to retrieve your surveillance video and examine the body before we can make a conclusion." (End of this chapter)
