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

Luo Fei was silent.

It seems that although Ning Zidong, the project manager, still hides a lot of secrets, for the other party to reach this point, there must be more than one confusion in his life.

It's just that this account has benefited him a lot, and no one else knows.

But there is no airtight wall in the world, and there must be someone in the entire chemical plant with something wrong.

Apart from him, the project manager, the only person who has access to this level is probably the factory director.

However, the factory director never intervened. It was most likely that Ning Zidong had settled the accounts himself, or was causing trouble in private, so that he could enrich himself and enrich himself.

It all has to go through one person.

finance!

Yes, according to the above conditions, Ning Zidong must be a good management talent, and he has been stable for several years.

"Ms. Du, I would like to ask you about your husband's brother, Ning Zitao."

Hearing these words, Du Yuhan's eyes softened a lot.

"Zitao, this kid is really good. Unlike his brother, he has a sense of righteousness in his bones. He is a very good young man."

"It's a pity that he is introverted and doesn't like to make friends, so his circle is very small. On weekdays, he only spends some time on business with his brother, and he doesn't have any special hobbies at other times."

Listening to Du Yuhan's narration, Luo Fei and the others seemed to see another person.

A completely different Ning Zitao!

Lin Jie and He Xin, who were standing next to him, both remained silent. After some discussion and research, they all agreed that they had a very bad impression of Ning Zitao.

As a murderous maniac with nine lives in his hands, he actually packaged his appearance so well.

It's really abominable!

Even his own brother is not spared!

It is simply unforgivable that such a beautiful home is now in pieces.

But at this moment, Luo Fei's eyes became more and more confused. He seemed to see something in it, but he didn't dare to judge.

"Ms. Du, I want to see your husband's room."

"Okay, please come with me."

Luo Fei stood up and left with Du Yuhan. At the same time, he turned to look at Lin Jie and He Xin, asking them to take photos and collect evidence at any time, because there might be other clues.

Entering the room, the two children were looking at Luo Fei timidly.

No one else spoke, but Du Yuhan sat aside and wiped her tears, thinking of her husband emotionally. This must be the most painful moment for a woman.

Luo Fei walked around inside and basically had an idea in his mind.

"Ms. Du, I have a different answer here, thank you."

Seeing Luo Fei like this, Du Yuhan was a little confused.

Lin Jie and He Xin, who were standing behind, were even more confused and didn't understand what the team leader was talking about.

After leaving, Luo Fei's phone rang. It was a call from the team.

"Luo Fei, two pieces of information. The first one is that there is indeed something wrong with Ning Zidong. He has had nearly twenty business transactions with false reports, and he has taken most of the rebates and profits himself. In addition to There’s not a lot of cost recovery, there’s not a lot of profit, but that’s not documented.”

"The second one is that we unlocked Ning Zitao's mailbox. Although we used some tricks, we found a very valuable point in it. The chemical plant finance department once sent him an address. Although we don't know what it was for, But that’s the most important thing in it.”

"good!"

Luo Fei had a smile on his face.

I was finally able to connect it all.

Combining everything that happened above, Luo Fei took the other two people and dared to go there. It was a public locker located in a comprehensive pedestrian street in the city.

"Team leader, I'm becoming more and more confused about Ning Zitao and his brother. Is it because he and his brother share the spoils unevenly? Or is it because they were originally the same species and now they want to keep it all for themselves, so they killed him."

"Yeah, I don't understand either. How does finance get involved?"

Luo Fei sneered, and the light in his eyes became brighter.

"Actually, this has always been a matter between the two brothers. I think the dispute between Ning Zitao and Ning Zidong was the trigger that led to the tragic death of these nine people. The finance and seven other workshop employees were also affected."

As soon as these words came out, He Xin and Lin Jie nodded. This relationship is the only explanation that can be explained at present.

As expected of the team leader, his thinking is really sharp!

"It's so big here, how can we find it?"

"What else are you looking for? Just check the surveillance."

Luo Fei pointed to the camera on the side.

"The monitoring in their chemical plant is under their control. Could it be that this place is also under their control? Although it has been a long time, we still have to give it a try first."

Arriving at the nearby management office, Luo Fei and the others found the person in charge and proposed investigation, surveillance and evidence collection.

The person in charge immediately started to investigate. There were not many surveillance records of this generation, and the camera facing the safe was always working.

"I'm really sorry, comrade police, that was monitored four months ago. We have covered it with data and it was automatically updated. There is really nothing we can do about it."

The person in charge's answer was a direct pour of cold water.

Hearing what the other party said, several people were instantly disheartened.

"But there's still a chance."

The person in charge suddenly remembered something.

"Last month, two comrades from the city police came here to investigate a theft case and retrieved a whole month's surveillance records, which have been backed up."

"Judging by the time, there should still be traces of the part you need."

Luo Fei's eyes instantly showed surprise.

Mountain darkly, vista!

"Let's go back to the team first."

Back in the team, Luo Fei and the others immediately applied for permission.

We immediately coordinated with the police. Fortunately, the backup data at that time was still preserved, so we transferred it.

Luo Fei found that scene according to time in the surveillance video!

The person standing in front of the locker was Ning Zitao. He opened the safe, took out a large mountaineering bag, opened it and checked it.

"stop!"

"Zoom in, zoom in again!"

Luo Fei and the others moved closer, staring at that part closely, and finally saw clearly that they were bundles of banknotes.

"Good guy, so much money? It turned out to be a bribery. No wonder the financial officer sent a special email. He wanted to trick Ning Zitao into seducing him."

The meaning of He Xin's words was very clear.

As long as Ning Zitao accepted the money, he was on the same boat, and that email was evidence. Unexpectedly, it actually became evidence.

"That's right. It does fit the current situation."

Luo Fei nodded.

Lin Jie pointed to the date above and started calculating.

"How long was the date on this before he and the factory director went to report the crime? It seems to me that it's not that far away. No, the date of the report was mentioned by Team Leader Zhou. It should be at the beginning of the month four months ago."

"Eleven days."

Luo Fei's memory was naturally no joke. He had firmly memorized all the news and clues given by Zhou Fan before.

Therefore, when I saw the time on the surveillance screen, I immediately thought of the interval between the two events. In these eleven days, nine major murders occurred.

This is enough to show that the conflict between the two brothers has taken a new turn from this moment on.

"Team leader, look..."

Suddenly He Xin shouted from the side.

Luo Fei approached the screen again. In the screen, Ning Zitao was talking on the phone, with his hands on his waist, feeling a little angry.

"What's going on? There's a conflict? Who are you calling?"

"I don't know, but looking like this, I must be quite angry."

"enough."

Luo Fei stood up with stern eyes. He already knew everything and was going to confront him next.

I have to say that this Ning Zitao is really a master!

This drama was played so superbly that if I hadn't spent a lot of effort on overt and covert investigations and repeated verifications, I would have been fooled by the other party.

But it's still too whimsical to want to do something under one's nose.

"Let's go, go back to the chemical plant, contact Team Zhao, and prepare to close the network."

"yes!"

Then the group set off and returned to Longke Chemical. All the previous investigations were just for this last moment.

Because Zhao Donglai and the others had sent people to monitor this place, no one could go out. Ning Zitao was still here at this moment.

"Captain Zhao, how's it going?"

"I'm just waiting for you. How's it going?"

"It's basically been solved, and now the final problem has been investigated. It's time to meet this guy."

When the guard saw groups of police cars coming to the door, he opened the door without saying a word, stood at attention and saluted, very strictly.

He Xin and the others also smiled and greeted the uncle.

Entering the factory, Luo Fei led people straight to the innermost area and found Ning Zitao in the office on the second floor.

At this moment, Ning Zitao didn't realize at all that he was in danger. He thought he was here to investigate and collect evidence this time, so he stood up and walked forward to say hello warmly.

But the cold looks from everyone made him feel a little weird.

"Comrade police officers, do you have any new clues?"

"Thank you for your hard work. On behalf of my brother, I would like to thank you all."

He still looked sincere and sincere, but at this moment, no one, including Zhou Fan, believed the other party anymore.

Based on the previous evidence, the numerous evil deeds committed by the person in front of me are outrageous.

Zhao Donglai snorted coldly.

"No need to pretend anymore, we are going to take you back for investigation. Now all the evidence points to you, as the biggest suspect in this case!"

"What? Me?"

After hearing what the other party said, Ning Zitao looked confused, and then smiled awkwardly.

"Did the comrades in the police make a mistake? I was very cooperative before. How can they find out about me now?"

"Is there any misunderstanding here? I am very heartbroken about my brother. How could I be the real murderer?"

"In that case, let's make it clear here."

Luo Fei walked out.

Now I have the most complete chain of evidence.

He knew very well that the other party would definitely quibble, because most of the previous evidence had been destroyed by him, and many details had been meticulously done.

If he hadn't connected all these details together, this guy would have gotten away with it.

"Let's talk about your modus operandi first."

"Those people are not missing at all. It is impossible for them to leave here. The surveillance does not show that any of them are outside the factory area. In fact, they all died here, and they were tortured to death by the acid solution. Your chemical plant is full of The murder weapon."

"I was very curious about where the hemp rope marks outside came from. In fact, you control them and use ropes to hang them in. This will not alarm the alarm and expose them to the hydrofluoric acid solution. Among them, it slowly corrodes to death.”

"All nine of them were more or less killed by you for some reason!"

After hearing what Luo Fei said, Ning Zitao waved his hand.

"Officer Luo, you can't say that about this. How can you be sure that I am the criminal with nothing? We have to rely on evidence for everything. It would be too inappropriate for you to make subjective assumptions about everything."

Seeing the other party's playful smile, Zhou Fan couldn't help it.

When I thought about being deceived by this guy before, I felt furious inside.

"Be serious!"

Ning Zitao had no choice but to put away his smiling face.

"The analysis is very similar to the plot. Isn't this the clip that Officer Luo found somewhere to convict me? I am really unjust."

"Whether you are wronged or not, we will find out once we investigate!"

Luo Fei sneered.

"Those high-concentration solutions of hydrofluoric acid will corrode skin and flesh, and will burn after contact. It can be said to be the best way to destroy corpses, but there is no perfect way to evaporate. The remaining limbs and broken arms should be The pipe is stuck down there."

As soon as these words came out, Ning Zitao couldn't sit still.

He didn't expect that the other party would notice this.

"If you don't believe it, let's keep it official! Notify all units, turn off the valves, and check the pipelines!"

As soon as these words came out, a hint of viciousness flashed in Ning Zitao's eyes, and Luo Fei saw all these details.

Soon the outside employees and public security operatives found the items.

A large cloth bag of bone fragments and the remains of a spine riddled with holes.

When these things were served, a few police officers present couldn't bear it anymore, so they covered their mouths and ran out.

There was a pungent smell and a strong smell of corrosion. Of the nine people, only a handful of scattered bones were left.

How miserable and unimaginable.

"No, I didn't do this."

"Officer Luo, police officers, I was wrongly accused. I did not kill anyone. I really did not kill these people."

"By the way, there is something I want to report. I found evidence of my brother's corruption and false accounting before. I was going to report them. Who would have thought that they would die? This really has nothing to do with me."

While talking, the other party dropped another bombshell.

Zhao Donglai and the others looked solemn. They didn't expect that there was such a hidden part. It seemed that this guy was hiding a lot of things.

"You want to report your brother? It's really just a matter of justice to kill one's relatives."

Luo Fei stared at the other party closely.

Ning Zitao took a deep breath, picked up the phone and hurriedly handed it to everyone.

"Police officers, I was really wronged. I just wanted to report them, but I didn't expect that they were already killed. It's impossible for me to kill someone for such a trivial matter... I have no motive."

Seeing the other party's anxious and flustered look, Luo Fei finally said something that shocked everyone in the room.

"You don't have a motive, but your brother does!"

"It is true that the murderer was not Ning Zitao, and he is indeed not the same person, but the prerequisite is that you must also be him."

Ning Zitao was stunned.

"What do you mean?"
