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

"This Qin Jianbin actually meets the conditions so well?"

Seeing the clues collected so far gathered together, Liao Xingyu was extremely excited, and Zhou Fan also widened his eyes.

"yes."

Luo Fei breathed a long sigh of relief and looked at the man in the photo and his identity introduction, his eyes filled with determination.

Not only did he have the same hallmarks as the murderer, but he also worked on electronic locks, so he had the conditions to commit the crime.

"The conditions have been met, what is missing now is his real motive for committing the crime and other evidence!"

Luo Fei shook the information in his hand.

"It seems I have to go to Kangcheng Electronic Technology."

This perverted murderer is very dangerous. In order to ensure that no other people will encounter accidents in the future, the identity of the other person must be determined as soon as possible and controlled.

Let’s put aside the other three big brothers for now. The main target is Qin Jianbin, who is the most suspected.

In this way, a group of people rushed to Qin Jianbin's company.

After arriving at the company, I inquired and found out that the other person was not in the company now, and had been away for three or four days in a row. He had been quite busy recently.

Regardless of whether they asked the front desk or other department managers, they all expressed their incomprehension and ignorance about Qin Jianbin's situation.

"Mr. Qin? Oh, that's strange. I've been in a bad mental state recently. I'm always in a trance."

"Yeah, yeah, we asked around and heard that it's a relationship issue, but we can't say for sure."

"Although Mr. Qin has strong work ability and high professional level, he is always absent from work and it is difficult to explain to the boss. The chairman has reminded him many times, but Mr. Qin still goes his own way."

Everyone basically has the same testimony regarding Qin Jianbin's question.

Facing such a situation, Luo Fei was a little helpless, but since he was already here, he couldn't go back empty-handed.

Immediately, Liao Xingyu and the others rushed to the other party's office to check if there were any other clues.

If the other party is the person in charge of the electronic lock field, there must be relevant evidence here to prove that he is related to this matter, which is very important.

Although the evidence has been proved before, it is not sufficient.

Because some confidential documents were not in the other party's office, the company employees did not pay too much attention and took Luo Fei and others over.

In the office, Luo Fei saw a display of electronic locks.

"These were all designed by our boss Qin himself before. Because he was promoted from the technical department, his professional ability must be the strongest here."

"These are new products developed in the past two years, and the sales are very good. We also recommend them to people around us."

The staff on the side followed the introduction.

Luo Fei and the others were walking and looking, and were suddenly attracted by an electronic lock in the center.

"photo."

Liao Xingyu took out the content recorded on the scene before and compared it. The two of them instantly understood that it turned out that these were arranged by Qin Jianbin.

"Please help us check the user information. Have these two ladies provided business services with you in the recent period, almost half a year?"

Luo Fei gave them Jiang Qing and Guo Wei's personal information, but after seeing the information, the staff was a little embarrassed.

Logically speaking, what they are doing here is confidentiality. Some electronics offices are more strict about confidentiality and cannot leak user information casually.

Although the criminal police investigation was a business matter, he did not say it clearly and was just thinking about whether to report it to the leadership.

Seeing that the other party was a little embarrassed, Luo Fei directly told the reason calmly.

"They're all dead."

"These two ladies were accidentally killed because there was a problem with the lock at the murder scene. Don't worry, it's not a quality problem, but there are some hidden secrets, so we need to verify whether there is a relationship between the two parties."

"understand."

The staff was already a little panicked.

They didn't dare to delay such a matter where lives were at stake, so they immediately went to investigate. Luo Fei and Liao Xingyu came to the office on the first floor to wait.

Logically speaking, Qin Jianbin, as the company's department leader, would not leave at will and remain absent from his post for such a long time.

The other party's disappearance during this period is even more strange.

In addition, he led the R\u0026D and design of that lock!

Luo Fei thought quietly. If there were any details that he missed, it should be Qin Jianbin's familiarity with these locks.

If it is really possible to enter at will, then why does it need to be demolished?

It’s nothing more than a cover-up!

The information was quickly sent over. According to feedback from the staff, Jiang Qing and Guo Wei had indeed ordered their company's locks not long ago, the exact time was a month ago.

However, the accounting list was indeed in Qin Jianbin's name, and the other party used his own account.

In other words, the so-called lock change was actually prepared by Mr. Qin for the two victims.

"It's really him!"

Liao Xingyu suddenly stood up with a serious look in his eyes. Now there is basically no need to ask, this guy must have tampered with the lock.

"Find the person in charge of your technical department. We have something to discuss with them."

Luo Fei continued to look at the user information, and it seemed to be what he thought at the beginning.

There is a certain dispute between them!

All of this started after I became the top brother on the list through rewards.

Because the reward records occurred during these three months, and the locks given to the two female anchors in the name of Qin Jianbin were a month ago, which means that they must have met offline. of.

Soon two men in work clothes came, looking honest and honest. They quickly stood up after entering the room.

"Hello, police comrades, we are the technical department responsible for after-sales and maintenance. My surname is Tong and his surname is Yan."

"Okay, Master Tong, come and take a look at this lock."

Luo Fei pointed to the broken lock on the photo.

"This is the sixth-generation new electronic door lock that Mr. Qin led in research and development and led us to develop it. It is a product that integrates fingerprints, passwords, and facial recognition gestures."

"After the appearance setting of this lock is changed, is it possible that it can be opened by outsiders or cracked by staff within your company?"

The other party nodded quickly upon hearing this.

"It is possible, but it requires upper-level authority and signed after-sales service requirements before it can be used, otherwise we will not be able to restart."

When asked this question, the two masters panicked.

"Comrade police, we have all filed a record, but we don't know about this matter."

Seeing them like this, Luo Fei and Liao Xingyu smiled.

"You two have misunderstood, and it has nothing to do with you."

"Okay, thank you for your cooperation, everyone can go back."

After seeing off the two masters, Luo Fei calmly looked at the office above.

"This guy must have other thoughts. The emotional entanglement with the female anchor is now the first investigation factor, and we are preparing to arrest Qin Jianbin."

"good."

Other police officers on standby were then arranged to take action.

Not only Qin Jianbin's home, but also all the other places he haunts must be thoroughly investigated to find the other party's recent whereabouts, and this dangerous person must be targeted as soon as possible.

But at the same time, Luo Fei thought of a serious question.

It's not enough to find the other party's movements, they must be arrested as soon as possible. Jiang Qing and Guo Wei are definitely not the only victims. What will happen next time?

Now many of the company's famous female bloggers have no longer appeared, and they have chosen to broadcast collectively to protect their own safety.

But if this is the case, then even if there is an accident, I won't know it.

If you want to lock the opponent's position again, isn't this the same as crossing the river blindly?

In this case, the situation would be too contradictory.

Thinking of this, Luo Fei became a little worried. At this time, Liao Xingyu rushed over with the information.

"Luo Fei, I found a problem."

"Qin Jianbin's account has been debited for a total of four sets of electronic locks in the past month or so. I asked the accountant to check and found that they are indeed the same model. Three sets have been shown to have been installed at home, and one was just installed a few days ago. reserved."

"That is to say, only he can open it and bypass the permissions because he is qualified to restart it on behalf of the after-sales service."

Luo Fei didn't care about the second half of the sentence, but was attracted by the first half.

Four in total?

Two people are dead now, which means there are still two female anchors who are in danger.

Luo Fei quickly started collecting information and soon found the remaining two ladies.

They are also female anchors of online live broadcasts, one is named Zhou Shanshan and the other is named Wang Han. However, Wang Han's door lock has not yet been scheduled to be shipped, which only shows that the other party has been busy recently.

And Zhou Shanshan’s has been installed!

If his prediction was correct, the reason for the continuous killings was because the homes of these female anchors were easy to get into, so Qin Jianbin would take this opportunity to go in and commit murder, and then fake the traces of demolition.

"Quickly, go to Zhou Shanshan's house."

The group of people got in the car and rushed to Zhou Shanshan's home, but there was a traffic jam just outside the apartment area where the other party lived.

Seeing that there was less than one kilometer away from the apartment building, Luo Fei got out of the car and ran away so fast that everyone was stunned.

They have never seen anyone run like this! Just like the swifts crossing the river or the eagles flying across the sky.

Soon Luo Fei braked suddenly, flew over the guardrail outside the community, and rushed inside.

Following previous instructions, he came downstairs to Zhou Shanshan's apartment, but at the same time he felt that something was not good.

Because there was a car parked right next to it!

The luxury of this car is definitely worthy of Qin Jianbin's status. It is reasonable for a rich man who can be the top brother of three or four female anchors to drive a coupe worth more than one million yuan.

Maybe the other party has already killed him...

Luo Fei looked up and saw that Zhou Shanshan's family lived on the seventeenth floor. It was unrealistic to check the floors with bare hands like before, so he had to force his way in.

When he came to the elevator, he found that the elevator stopped at the seventeenth floor.

"broken!"

At this moment, Luo Fei had realized that the other party was up.

According to the previous communication with Master Tong, he knew the process and time of restarting and updating the electronic lock. If he wanted to avoid the password alarm, he had to reset the system first. The specific operation time was about five minutes. After the operation was completed, the identity could be verified. Turn on the electronic lock in factory settings and get inside.

When it comes to going up and down the elevator, I might not be able to make it in time.

If ordinary people faced such a situation, they would probably just sit back and watch the murder happen.

But I am different.

Luo Fei didn't hesitate and started running upward from the fire escape on the side.

According to his understanding of himself, it would probably take him less than ten seconds to reach the next floor by taking three steps and one step at a time.

The seventeenth floor means less than three minutes is enough!

Just like that, Luo Fei charged with extremely fast movement and leg strength.

Sure enough, he rushed to the seventeenth floor in less than three minutes.

The moment he reached the floor, he saw a door at the corner opened. The lock on the door was the electronic door lock that Qin Jianbin recommended to these female anchors.

There is no mistake, this guy has already entered!

Luo Fei rushed in quickly, and the noise of things falling and fighting could be heard in his ears.

The moment he pushed the door open, he saw an astonishing scene in the bedroom.

Still the mysterious man wearing sportswear and a yin-yang mask!

Black air lingered above the head, and the thick murderous intent condensed into a ferocious appearance. From the eyes of sin, there was no doubt that the opponent was Qin Jianbin with a life in his hands.

At this moment, he was holding Zhou Shanshan's neck with one hand and pushing her down on the bed.

At the same time, he held an iron rod in his hand and beat the opponent's arms and body, roaring ferociously while beating him.

"Hahaha, bitch, I've given you so much, but you're having a great time here!"

"In this case, then go to hell and see who will remember you after you die."

Zhou Shanshan, who was lying on the bed, kept struggling, but she was also a little exhausted. There were bruises all over her body. It was obvious that the two had just had a brief confrontation.

Luo Fei rushed over and punched the opponent away.

The power of this punch was something that Qin Jianbin, a mere mortal, couldn't handle...

After knocking the opponent to the ground, Luo Fei hurried up to check and found that Zhou Shanshan was already showing signs of fainting.

There was no other way, Luo Fei didn't care about anything else, he picked him up and walked out.

Suddenly a figure jumped up from behind, and Qin Jianbin endured the severe pain and used the iron rod in his hand to hit the back of Luo Fei's head.

At this moment, his mask has fallen off, but the madness in his eyes is even more ferocious.

"Hmph, seeking death!"

Luo Fei turned around and kicked him forward, directly hitting the opponent's chest with a forward kick.

boom--

The other party hit the wall again, and then began to vomit blood.

Fortunately, he restrained his strength, otherwise this kick would have been enough to send the opponent to heaven.

Seeing this scene, Luo Fei shook his head.

The fact that he dared to take action even though he was wearing a police uniform showed that Qin Jianbin had reached the level of madness, and if he had been a few seconds late, he might have been unable to recover.

"Hehe, I'm going to kill you... kill them all. You bitches who deceived me will not have a good death."

In the end, Qin Jianbin passed out after muttering a few words.

Luo Fei carried Zhou Shanshan into the living room, put her down, and then checked her carefully.

His arms and ribs were broken, and his legs were bleeding, but there was no danger to his life.

At this point, this perverted live broadcast murder case is finally over.
