After rebirth, he surrendered with the stolen goods.

"Take over women of different heights and sizes and let them take a look. Remember to cover their faces and necks. Don't let them know they are women. Modify the photos a little."

After hearing what the other party said, Zhao Zhiguo thought for a moment and said.

Although it can be seen from the interrogation of Huang San and Li Sha that they are very sure that the suspect is a male, there is one thing that Zhao Zhiguo has to consider.

When they met, the other party never showed his true face. The same was true in all the found video images. In the very hot weather, he was wearing long sleeves.

Wearing a mask is nothing strange now, but wearing long sleeves while walking outside in the summer is questionable.

Of course, it may also be that the other person has some obvious features on his arm, such as a tattoo or a birthmark.

However, all doubts need to be verified or broken one by one. This is also a way for them to undermine the case.

As for why the female features in the photos were hidden, it was because they were afraid of direct denial from Huang San and Li Sha.

Another point is that the other party's hair is also quite long, which is also one of the reasons why Zhao Zhiguo is suspicious.

Nowadays, it is not strange for women to have short hair, not to mention that the other party's hair is not short, but the hairstyle is commonly used by men.

"Okay, I'll send it to the technical department and let them help with it."

"Well, go ahead and let them finish this first, and then send it over as soon as possible for Huang San and Li Sha to identify it."

03:30 am

Hanhan, who had already woken up from sleep, stretched his head out of the car window in high spirits and looked at the silent campus in front of him, full of emotion. He did not expect that the final result would be as Zhao Zhiguo speculated.

When identifying people, Huang San and Li Sha jointly identified a teacher who had just joined the No. [-] Middle School in the city.

This teacher is Wang Bo, who was specially recruited to enter the city's No. 27 Middle School this year. He graduated with a doctoral degree at the age of [-] this year, and the course he teaches is chemistry.

With the opponent's knowledge, it is completely easy to use the school's chemistry laboratory to make a simple bomb.

City No. [-] Middle School is a day school, so at night, except for people in the staff dormitories, there is no one else. When the police arrived, they kept quiet and tried not to make any noise.

After a jc briefly communicated with the man on duty in the security room at the entrance, the school door opened directly.

The car soon arrived below the laboratory building. A person in charge of the school was already waiting downstairs. When he saw Zhao Zhiguo, he walked over quickly.

"Principal Liu, I didn't expect that I would need to trouble you to come over so late at night."

"Haha, Director Zhao, you see what you said, isn't it our responsibility to cooperate with you? Besides, given our friendship, do we still need to say this?"

The two people shook hands briefly and briefly said that they needed the other party's cooperation, but the specific details of the case were not disclosed to the other party.

After listening to what Zhao Zhiguo said, Principal Liu immediately took out a bunch of keys, opened the door to the laboratory building, and then went inside to turn on the lights.

After doing this, Principal Liu handed the keys directly to Zhao Zhiguo. Each key on it had the corresponding house number written on it, which was very easy to identify.

He knew that he could not get involved in the following matters, so he readily handed over the key to Zhao Zhiguo without waiting for him to say anything.

After this was done, a group of people were arranged to follow Principal Liu to the suspect Wang Bo's dormitory to arrest him, while Hanhan was left in the laboratory building for inspection.

In addition to Hanhan, there are two other explosive detection dogs. Their task is to check whether there are explosives in the experimental building.

No one knows whether Wang Bo, with his madness, would place a bomb in the laboratory building and wait for JC's arrival.

Based on the information on Wang Bo that has been investigated so far, the reason why the other party did this has not been found at all.

Wang Bo's family is considered a well-off family. Both his parents are teachers. With the help of his parents, he has a house and a car at the age of 27.

Things went smoothly at work. After graduation, I joined the city's No. [-] Middle School as a teacher and became a specially recruited teacher.

The salary is also very good.

Except that he has never had a girlfriend so far, he thinks that his life is better than most people.

You can hardly find a reason for the other person to do this.

The JC involved in handling the case has not yet determined whether it was Wang Bo who did all this.

If Huang San and Li Sha hadn't been so certain that they were each other, and they also found figures that looked like each other in the surveillance video, neither of them would have come over.

The laboratory building has six floors in total, with four chemical laboratories on each floor. Hanhan is responsible for the first and second floors.

The three jcs took apart the key chain, and each person was responsible for following a police dog and opening the door of the laboratory after their inspection.

As for why you don't open it directly, haha, you will have no surprise later.

(Many seemingly unreasonable requests often have one or more histories of blood and tears behind them)

When facing such a smart suspect, you must be cautious. After all, the laboratories in the laboratory building are not used every day. It is normal for some to not be used for several days.

Hanhan sniffed carefully at the door of the first software laboratory. In order to prevent missing something, he specifically asked Zhao Feng to pick him up and sniff the door.

After making sure it was safe, he nodded to JC beside him.

So jc is already used to Hanhan's performance. This is not the first time they have cooperated, and they know Hanhan's IQ.

But there is nothing surprising. Police dogs that are so smart are not too rare in police dog bases.

Of course, this means that he has never really seen Hanhan's IQ, otherwise he wouldn't think so.

After opening the door, Hanhan walked into the laboratory and sniffed every corner of the laboratory carefully.

The entire laboratory is filled with a variety of pungent odors, which greatly affects the ability to smell. What originally took one minute may now take three minutes to complete.

(Some odors may no longer be smellable to humans after they are ventilated, but they are still very obvious to dogs with a sensitive sense of smell)

Hanhan searched a laboratory for more than ten minutes before finishing the inspection.

The second laboratory may not have been used for several days, so the smell inside was not too strong. Hanhan's inspection speed was much faster, and the inspection was completed in a short time.

When Hanhan came to the third laboratory, he smelled a familiar smell without even sniffing carefully when he walked to the door.

When Hanhan was put down by Zhao Feng, he nodded to the two people next to him, indicating that there was no problem.
