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

"Deng Chengzhen, guess what we found in the reservoir near the estuary?"

Speaking of which, this guy is really unlucky.

Two years ago, there was no filter installed at the Changli City Reservoir.

But when he committed the crime, the filters were already installed. "So we went to the area near the filters and found the body almost immediately."

Luo Fei was very sure that Deng Chengzhen was simply evil.

He just thought he was a big star in the past.

Still living in the dream that he was once extremely popular and could do whatever he wanted.

But actually.

Most of the time, the more people with this kind of personality he has, the more likely he is to suffer losses and run into obstacles.

It’s just that most people may reflect on themselves.

"In fact, most people, if they realize they have made a mistake, will probably take the initiative to admit it."

"On the contrary, there are very few people like him who even go so far as to kill people."

In the afternoon.

Luo Fei and his friends were drinking to celebrate.

Both cases were successfully solved.

Lao Han serves as the deputy captain.

At this meeting, I also took the initiative to build bridges.

"Everyone, to welcome the goddess Wang Simeng to our serious crime team for exchange and learning, I think we should all toast her together, okay?"

I was very excited to see Lao Han so happy.

Su Jianfan shook his head.
"Old Han, you've offended a lot of people with this statement. All the girls in our serious crime team are outstanding women, both talented and beautiful."

"In the end, Officer Wang came to communicate, and you just flatter him. Be careful or I'll go complain to your little girl later."

Originally, Old Han felt a little aggrieved.

But I heard that Su Jianfan was going to complain to his daughter.

He also quickly begged for mercy.

"No, no, no, brother Jianfan, I was wrong. It's not okay for me to be wrong."

"Otherwise, if Tiantian finds out, I'll be in trouble."

Seeing the other party was terrified.

Luo Fei smiled and shook his head.

"Su Jianfan, if you say so, who do you think is better at investigating cases, Wang Simeng or the female police officer in our team?"

Luo Fei actually took action himself.

Asking such a question is clearly an attempt to embarrass yourself.

Su Jianfan was also suddenly embarrassed.

"Team Leader Luo, I was wrong. Why did you suddenly ask this? I don't know how to answer."

But I saw that the other party was in embarrassment.

Old Han said.

"Brother Su, this is what you don't understand. You should say that everyone is unwilling to give in to each other and each has his own merits."

Li Yu, who was standing by, couldn't help but be amazed when he heard this.

"Old Han, you've got this bowl of water really evenly balanced, right?"

For a moment, everyone couldn't help laughing.

It was amazing to see that the atmosphere in the serious crime squad was so harmonious.

Wang Simeng seemed to be worried.

This also aroused Luo Fei's curiosity.

"What's wrong, Wang Simeng? Is this meal not to your taste?"

"Everyone, thank you very much for preparing this dinner for me. But I really didn't expect the murderer to be so cunning. Until now, we have not found the real culprit in the radiator head-knocking case."

Such a reminder left others speechless.

And watching everyone remain silent.

Deng Wen brought good news.

"Team Leader Luo, just a little while ago, we found a person whose DNA data seemed to match the person who hit his head with the heating pipe."

"In addition, we specifically found an eyewitness and made a profile based on his appearance. The person's appearance is about 60-70% similar to the painting drawn by the close-up artist."

Hear this.

Luo Fei nodded.

"Then it's probably close, right?"

Because under normal circumstances.

The profiler is in a situation where there is absolutely no physical object.

Imagine what a person looks like out of thin air.

So it can be around 50%.

People with even higher similarities are mostly suspects.

Not to mention.

The other party is still using a fake identity to book a hotel room.

So Luo Fei and his team immediately sent the new recruits trained by Su Jianfan to form a special task force and head to the crime scene.

Just saw it this time.

Wang Simeng was a little surprised that Luo Fei did not take action personally.

"Team Leader Luo, this time... you don't plan to take charge of the case yourself?"

Seeing that the other party was a little surprised, Luo Fei shook his head.

"Some cases can be handed over to our subordinates. After all, the chain of evidence is basically complete now."

"As long as the person is caught and confirmed to be him, the case can be closed."

Luo Fei knew it very well.

Because this person did not leave any traces at the scene.

But his modus operandi was very primitive.

Although it is roaming around the country, it is hard to say for sure.

Because thanks to his crimes he has never been caught by the police.

Therefore, it is very likely that this guy has not changed his tools until now.

dong dong!

at this time.

There was a knock on the office door.

"We're eating right now. I guess I came at the wrong time?"

"Nothing."

Because you may have to go on a mission at any time.

So Luo Fei and his team were working overtime tonight and didn't leave at all.

Otherwise, Lao Han would have suggested going to the night snack stall opened by Lao Ma at the beginning.

At this time, Old Han was also a little surprised.

"Director Guan, why are you here?"

But as the door opened, I saw Guan Songhu standing at the door carrying something.

Luo Fei was also surprised.

Guan Songhu said with a smile.

"Team Leader Luo, I heard that you have been doing very well in investigating this case recently and have made remarkable achievements, so I specially sent you a few silk banners that I collected, as well as a 10 yuan bonus."

Although it may be normal.

It is impossible to pay so much money for one case.

But Luo Fei and his men acted with swiftness.

It can be said that several major cases were solved together.

So basically this month.

They have even won the provincial pioneer police team award next month.

However, I know that the entire team has made an indelible contribution.

But he still smiled and was polite.

"Director Guan, this incident is indeed unusual."

"Thank you for your encouragement and support to our entire police force. We will continue to work hard to solve more cases."

See the other party swear.

Guan Songhu then nodded.

"Team Leader Luo, your entire team is excellent."

"But, I may have to let you take charge of a case next."

I heard the other party sound so serious.

Luo Fei thought it was some major case.

"Director Guan, what level of case is this? Is it a major homicide or something like that?"

Seeing that everyone else was a little puzzled.

Guan Songhu shook his head.

"Overall, it's not a major case, but it's really infuriating."

After Guan Songhu explained.

Only then did Luo Fei know.

It turns out that there was only one victim in this case, a single mother.

His eldest son was sleeping in the bedroom at the time.

The youngest son came home in the middle of the night and said he had bought a new massager for his mother.

The result was unexpected.

The power of this massager was so great that it actually electrocuted my mother to death.

"So this brat is now asking the insurance company for compensation, saying that the massage chair manufacturer did not design the product safely enough, which led to this tragedy."

You can hear it here.

Old Han and the others were a little skeptical.

"That's impossible. How much power does a massager have?"

"Wouldn't it be possible to just plug two batteries into this thing and it would work?"

Luo Fei also immediately smelled something wrong.

"Was it murder?"

Seeing that the other party has guessed the truth of the matter.

Director Guan could only sigh.

"Captain Luo, to be honest, although we have some speculations in this regard, we have no way to confirm it due to insufficient evidence."

"The deceased was found in the kitchen. Under her was a burnt hair dryer and a burnt and deformed power strip."

Hear the news.

Everyone's expression became somewhat solemn.

Old Han couldn't help but ask.

"What is his motive for doing this?"

"Is there some grudge between this mother and son?"

Guan Songhu shook his head after hearing this.

"That's not true. From what we know, this mother is very devoted to her son and has been the best to him since he was young."

"This caused his eldest son to be very resentful, but he only dared to complain occasionally."

Han Tiesheng listened.

Couldn't help but shake my head.

"People always say that loving mothers often spoil their children."

"It's probably because this mother dotes on her son too much that her son has become twisted like this."

Luo Fei was more straightforward.

"Director Guan, what do you think is this person's motive?"

"Team Leader Luo, I'll be honest with you. We checked this man's phone a long time ago and found out that he was looking for information on how to defraud insurance by faking an accident."

More than half an hour later.

Luo Fei and the others calmed down.

The target was taken to the interrogation room.

He also lowered his head, looking aggrieved.

It seems like I am a big complainer.

"Tell me, why did you do such a heartless thing?"

Seeing Luo Fei's suspicious look,

The man swallowed his saliva.

"Officer, I really didn't mean to do this. I just acted on impulse."

"Really? Tell me the truth, who would attack their own mother on impulse?"

The man bit his lip after hearing this.

"Officer, I really didn't intend to do this at first."

Seeing each other is very affirmative.

Luo Fei asked again.

"You didn't think anything, just say it clearly."

"I didn't expect to harm her by committing insurance fraud."

I saw that the man was very sure about what he said.

The brother outside the interrogation room was on the verge of collapse.

"Officer, I never dreamed that my brother would do such a thing."

At this moment, my brother was already confused.

Because he never thought that his younger brother would do something so excessive.

To know that all along.

My mother takes great care of my younger brother.

Even though he is over 30, he doesn't want to work outside.

He said that he had only saved more than 20 yuan over the years and felt useless.

His mother also said that it was okay for him to come home and find a job.

But who would have thought that such a mother who always cared about her son would be killed by her son.

"I was really wrong. It would cost more than one million yuan to buy a house, but I only had 20 yuan in savings. But I saw that if I could successfully get the insurance, I would still have more than yuan, so I thought about giving it a try."

The man said this with his brows lowered.

This left his brother outside dumbfounded.

I almost couldn't believe my ears.

He now wished he could just rush in and beat his brother to death.

But I thought, what if I was also thrown into prison?

Then I guess there will be no one left to take care of the funeral affairs by the mother.

He had no choice but to endure it temporarily.

I just thought about everything my mother had experienced before.

As for the behavior of this beast, my brother is now so angry that he is at a loss of what to do.

"This damn guy is so cruel!"

But what has happened cannot be undone.

The next morning.

When Luo Fei arrived at the serious crime department, Su Jianfan was reading the files.

You can see that he looks a little depressed.

Luo Fei asked again.

"You didn't sleep last night, did you?"

I was a little surprised to see Luo Fei.

It seemed that he didn't expect that he would have to work overtime for a whole night.

Su Jianfan shook his head.

"It's nothing, Team Leader Luo. I was just really angry when I thought about that person's behavior, and I couldn't sleep at all. So instead of going home and tossing and turning, I might as well write a clear case report for this case."

I saw that Su Jianfan's face was obviously alert.

Others were also relieved at this time.

"Su Jianfan, thank you for your hard work. This case investigation is all thanks to you."

I heard others praise it.

But Su Jianfan understood.

I just can't get over this case.

That's why I need a night to calm down.

He needed to keep himself busy so he wouldn't focus on it.

Just when Su Jianfan and others were discussing this matter.

Luo Fei also noticed.

At this time, Cai Junfeng was walking towards this side.

But his face was a little gloomy, which aroused Luo Fei's curiosity.

"Team Leader Luo, Sun Xiaomei last night was actually not an easy person to deal with."

As Old Han spoke, he took out a stack of photos.

However, the most important content is still screenshots of surveillance video.

After seeing these contents,
Luo Fei also shook his head.

"I said that people are looking for people, and this Sun Xiaomei is not simple either."

Hearing such news.

Su Jianfan's curiosity was also aroused.

"Team Leader Luo, could it be that the woman also has a criminal record?"

"Of course, obviously he wasn't completely forced."

It turns out that this woman was young.

Just have a premature love affair with your classmates.

She even went to her boyfriend's house to steal money under the pretext of being in a relationship with him.

There was more than one boy who had been robbed by her.

"Later, she and Deng Chengzhen robbed a bank together, but because it was a rural credit cooperative in a very remote place, and it was 10 years ago, some security measures were not yet sound. The security guards saw that they had guns and did not dare to fight them, so they had to let them go. In addition, there was no surveillance, so there was no sufficient evidence left."

But just heard the news.

Luo Fei's eyelids twitched.

"That's not right. If he didn't leave any evidence, where did you get these surveillance screenshots, Old Han?"

"What a coincidence. Perhaps the law is long and there is no loophole. The developer who was killed by this woman saved this video on his phone. Although I don't know how he got it, I guess he had already realized that these two people had bad intentions and might try to deal with him."

"That's why they left such evidence. With things developing to this point, we can only say that God does not hide evil." (End of this chapter)
