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

Just watching Lao Han's chest rise and fall violently, his head was covered with sweat.

Luo Fei was still laughing.

"Old Han, it turns out that I was right to ask you to come out with Su Jianfan to get things. Otherwise, if it were just you, you might have been so frightened that you just shot."

"No! I'm just in case!"

Old Han said as he pushed a few CDs to Luo Fei.

He asked a little worriedly.

"Old Han, have you backed up this CD?"

"Backed up. Otherwise, why do you think Li Yu didn't follow? She just brought the original surveillance video back to the bureau to copy it as a backup."

Lao Han's explanation made Luo Fei suddenly realize.

"It's best to have a backup. I have to destroy this CD after I finish reading it tonight. If I keep it, it will be a hidden danger."

Luo Fei said, walking to the living room and sitting in front of the TV.

Put the CD into the CD-ROM drive.

Turned on the TV.

Lin Qingshan also walked out of the bedroom at this time.

He said with a grateful face.

"Officer Luo, I really want to thank you this time. If it weren't for your sharper judgment, Su Fangfang might have been accidentally injured tonight."

Lin Qingshan looked at Luo Fei with some gratitude.

But Luo Fei acted as if nothing had happened.

"It doesn't matter, this is what I should do. And now that we know Su Fangfang's identity, we should pay more attention to her. After all, she is our key witness in solving the case."

But although Luo Fei said it very calmly.

But Lin Qingshan said with great gratitude.

"Officer Luo, I still want to thank you anyway."

But even though Lin Qingshan said this.

But Luo Fei told him.

"Officer Lin, actually speaking of it, there is something I wanted to tell you before."

"Now since you happen to be awake, I might as well talk to you about it together."

Luo Fei's tone was solemn.

This made Lin Qingshan a little curious.

"Officer Luo, what are you talking about?"

"That's right, I want to ask you, can you consider letting Su Fangfang go with me to meet the person who reported the crime tomorrow?"

Luo Fei's suggestion made Lin Qingshan hesitate.

But the next second.

He understood Luo Fei's intention.

"Officer Luo, do you want to see Su Fangfang's reaction after seeing that person to make sure that he is not a bad person?"

"Yes, if the other party is from Wang Chuan, then Su Fangfang might have seen her."

Luo Fei said and reminded.

"Just doing this will probably deepen Su Fangfang's psychological shadow, so I hope you will discuss it with her before making a decision."

"Okay, I understand Officer Luo, leave this matter to me."

Come down with the promise.

Lin Qingshan's expression also became more determined.

But I'm afraid he won't be able to sleep well tonight.

"Officer Luo?"

After a while.

Luo Fei suddenly heard someone calling him.

He also looked up suddenly.

"Ms. Tang, aren't you still asleep?"

At this time, Tang Shiyu bit her pink lips.

Her little hands were tugging at the hem of her skirt, as if she was hesitant to speak.

"Officer Luo, I can't sleep..."

Luo Fei couldn't help but be curious.

"Miss Tang, what can you do?"

It was obvious that Luo Fei was looking at him with some confusion.

Tang Shiyu explained quickly.

"Officer Luo, it's actually nothing. I just thought that instead of staring and losing sleep upstairs, I might as well come down and watch the surveillance again with you. Maybe we missed something last time and maybe we can find it this time. "

"I just don't know if Officer Luo will mind. Do you think I'm your scapegoat?"

Tang Shiyu suggested this, her beautiful eyes full of expectation.

It was obvious that she really wanted to help.

Luo Fei also moved to the side.

"sit down."

Tang Shiyu finally breathed a sigh of relief when he saw that he didn't reject her.

It's just that I'm watching the surveillance video.

But Luo Fei didn't know what he wanted to see.

There is no goal at all.

So you can only watch it carefully from the first minute, and don’t miss every frame.

This way you won't miss any clues.

"Officer Luo?"

at this time.

Tang Shiyu suddenly spoke.

Luo Fei couldn't help but wonder, what was she trying to say?

"Officer Luo, actually I think Su Fangfang is too pitiful."

"We should do something to help Su Fangfang, including victims of training classes like her."

Tang Shiyu's suggestion made Luo Fei nod.

"Miss Tang's idea is good. I think we can set up a charity foundation. If we encounter children similar to Su Fangfang again, we can help them through a charity foundation."

Tang Shiyu didn't expect that he and Luo Fei would coincide with each other.

So she readily agreed.

"Officer Luo and I really have the same idea!"

See her smile.

A smile appeared on her pretty face.

Luo Fei also smiled lightly and said, "If Su Fangfang knows this news, she will definitely be very happy."

"She will also be grateful to you and think you are a good person."

Tang Shiyu's face turned red when she heard Luo Fei's praise.

"Officer Luo, thank you very much. I did this not for her to thank me, but for my brother. Because I don't even know if he is still alive, so I don't want others to make the same mistake again, let alone watch those unscrupulous people People with bad intentions who want to make money get away with it.”

…

"Miss Tang?"

I don’t know how long it took.

Luo Fei felt something soft and fragrant leaning on his shoulder.

He took a closer look.

It turned out to be Tang Shiyu, who fell asleep because he was too sleepy.

"No wonder, it's already past 1 a.m. now."

At this time, Tang Shiyu's body exuded the delicious fragrance of shower gel.

There was still a trace of crystal clear hair hanging from the corner of her moist mouth.

It has to be said that the sleeping Tang Shiyu changed from his usual reluctance to others and became very cute.

Luo Fei just carefully put a pillow under her head.

He covered her with a blanket again.

Then continue to watch the monitoring.

…

"I found Miss Tang, I finally found it!"

I do not know how long it has been.

Luo Fei called out softly.

Tang Shiyu just woke up from his sleep.

He rubbed his sleepy eyes.

"Officer Luo, what did you say you found?"

As he woke up, Tang Shiyu realized that he actually slept next to Luo Fei last night and leaned on his shoulder.

Just thinking about it made her pretty face heat up.

"Ms. Tang, look carefully. In this video, there is a person wearing a work uniform!"

Luo Fei said, pausing the video and pointing at the screen.

Just looking at this man who is 1.85 meters tall.

And he was also carrying a tool box.

Tang Shiyu didn't see any clues.

"Officer Luo, are you mistaken? Isn't this person Officer Lin?"

She blinked.

But Luo Fei played the video backwards.

"No, Miss Tang, please take a closer look."

As Luo Fei played the video backwards.

Tang Shiyu saw it.

in the screen.

It was Lin Qingshan who took off his mask.

I asked someone in the office building where the bathroom was.

Not long after, a repairman came out of the bathroom.

Still holding his suitcase.

Moreover, the two people before and after entering and exiting the bathroom were almost the same in height and figure. In other words, they were the same person!

"Officer Luo, I really don't understand. Isn't this person just Officer Lin? I really don't see anything wrong with him."

But Luo Fei said.

"No, the person you saw coming out of the bathroom was not Lin Qingshan, but another person."

? ?

Tang Shiyu instantly became energetic and no longer sleepy at all.

"Officer Luo, you mean that Lin Qingshan was changed in the bathroom?"

But there is no secret passage in the bathroom. No matter which one of the two people leaves the bathroom, there will always be one person left inside.

"Ms. Tang, I actually thought at first that this man and Lin Qingshan were the same person. But after thinking about it, I felt something was wrong."

Luo Fei said, zooming in on the video screen.

He pointed at the left little finger of the person coming out from behind.

"Have you noticed that this man's little finger on his left hand is a bit unnatural."

"He also has his signature habitual action of a heavy smoker, which is to go to his jacket pocket to get a cigarette."

Luo Fei's reminder inspired Tang Shiyu.

"Yes, when we went to the maintenance company, even the manager said that Lin Qingshan never smokes."

"And his uniform didn't smell like cigarette smoke."

Although Tang Shiyu does not smoke.

But she had been to an Internet cafe at school before.

But just once, she never wanted to go again.

The reason is also very simple.

Because the leather sofas and keyboards in Internet cafes will have an indelible smell of cigarette oil, and most of them don’t know how to open the windows, so the air is really bad.

"And if Officer Lin smokes, he should also have the smell of smoke on his body. You can smell it without getting too close. But I didn't smell it in the car."

"That's right."

Luo Fei didn't finish his words.

Just then Lin Qingshan came out of the bedroom.

"Officer Luo, you guys got up so early?"

Luo Fei actually didn't sleep all night last night, but that didn't matter.

He just excitedly dragged Lin Qingshan to the screen.

I explained to him what I had just discovered.

And after listening to his reasoning.

Lin Qingshan also suddenly felt his blood boiling.

"Ms. Tang, when I went to your company that day, I didn't go to the restroom. I just happened to be able to reach the air conditioner outside through the restroom window. So I first asked my colleagues to put down the tractor and go outside the window so that I could go up and work. .”

Lin Qingshan explained this.

It was enough to prove that Luo Fei's judgment was correct.

Tang Shiyu also suddenly understood.

"I understand. This person entered the office building and then disguised himself as Officer Lin. After Officer Lin went to the outer wall of the building from the restroom window, he used the time difference to come out of the restroom so that he could cover his body without being noticed. And retreat.”

But soon, Tang Shiyu felt that such speculation was simply incredible.

"But how did this person enter the company? What was his purpose of sneaking in?"

Tang Shiyu was really scared, and she made up her mind. As soon as she returned to the company, she told the company's employees to strengthen patrols.

Suspicious persons must not be allowed to enter the office building casually.

Otherwise, the consequences would be unimaginable.

Who knows if someone with evil intentions will break in?

"But Miss Tang, I discovered it after careful observation just now."

"This person didn't just enter the building and dress up as a maintenance worker. He started out disguised as a security guard."

Luo Fei said, locking the screen.

When he saw a man wearing a building security uniform, his gestures and movements were exactly the same as the fake Lin Qingshan just now.

Tang Shiyu was even more curious.

"Why did this person enter the company? He probably wanted to steal confidential information. But in my office, unless I and the cleaning lady have access cards, no one else can enter."

Tang Shiyu was really scared, so he was uneasy.

Luo Fei also quickly comforted him.

"Ms. Tang, although it is not yet certain what his purpose is, from the approximately three hours of video, I found that he appeared in three places in total."

Luo Fei said and pointed at the screen.

"The first is to get on the elevator, and the second is to come out of the bathroom."

What about the third place?

This is a question shared by Lin Qingyun and Tang Shiyu.

Looking at the expressions of the two people who were so curious that they exploded.

Luo Fei took a deep breath and said.

"Although it may be a bit scary to say this, the last place he appeared was on the roof. And judging from the video, Ms. Tang was supervising the work on the roof at that time."

? ?

"Does he want to sneak in and push me downstairs next time?"

Tang Shiyu covered her mouth.

Fear and anxiety were written on his face.

Luo Fei also had to admit it.

"Ms. Tang, I know that this kind of reasoning may make you a little scared. But judging from the current situation, this possibility cannot be ruled out."

Lin Qingshan also analyzed.

"Is this very possible? After all, Miss Tang happened to have recently acquired Lotus Manor. As the police investigation deepens, you are likely to become more and more unable to accept the truth, and even more so, you will feel broken down by what happened to your brother."

"The other party can completely use this idea to create the illusion that you can't bear too much mental pressure and negative news, and eventually commit suicide by jumping off the building."

The two people's analysis suddenly made Tang Shiyu even more frightened.

"Officer Luo, what should I do? You must save me!"

Tang Shiyu's beautiful eyes flashed with an uneasy look.

Luo Fei quickly comforted him.

"Ms. Tang, it doesn't matter even if the other party wants to harm you. After all, we will all be by your side, and we will not let you be in danger."

Although Luo Fei said it very seriously.

But Tang Shiyu was still a little uneasy.

"But Officer Luo, if someone wants to harm me, you can't stay with me 24 hours a day, and I don't want to affect your work."

"It doesn't matter. Anyway, there is no progress in the case now. Everything has to wait until the autopsy report comes out. It doesn't hurt that we all take turns to accompany you during this period. After all, you are our important informant."

Luo Fei readily agreed.

But as soon as Lao Han got up, he saw Tang Shiyu wrapped in a blanket and nestling next to Luo Fei.

This made him suddenly feel gloating.

"Lao Luo, I'm going to talk about you. Miss Tang is a rich woman, how can you let her stay up all night in the living room with you?"

"If Miss Tang gets sick, wouldn't it be easier to become a target for criminals?"

Tang Shiyu blushed immediately after hearing this.

She originally wanted to explain that she was not staying up late with Luo Fei.

But I am afraid that I will become darker and darker.

Luo Fei didn't bother to explain.

Fortunately, there was a knock on the door.

"Lao Luo, Lao Han, are you there?"

I heard the voice of Guan Songhu.

Luo Fei was also a little surprised.
