Attending ex-girlfriend's wedding, arresting the groom's officer on the spot

Wu Kaiyue has not slept all night.

As the captain of the graphic investigation brigade, Wu Kaiyue's work is actually not too busy.

The graphic investigation brigade has developed extremely fast in recent years, and there is neither shortage of people nor money under its command.

Although Wu Kaiyue's promotion path is not that wide as the team leader of Tusun, but it is more than enough than the top.

Ordinary cases are not his turn to pay attention to.

But yesterday's traffic accident case was different. Qin Yong called him personally and made sure to find out the video of the deceased.

The superior gave the order to die, and Wu Kaiyue dragged the elites of the team to work all night, but there was no big gain.

The office of Chen Kun, the top expert of the Graphic Investigation Brigade.

Of course, Chen Kun is the main force of the graphic investigation brigade for this kind of big and important case.

At this moment, the leaders of several groups are also in the meeting room.

"For Group 320 and Group [-], last night, the [-] forks in the direction of Binzhou Road and the cameras of [-] were checked."

"The deceased was not found to have appeared in these surveillance cameras. The other party should not have come from the direction of Binzhou Road."

The work of image investigation is basically to find a needle in a haystack, looking for the few seconds of the picture you want to find from the massive surveillance video.

"How's it going on Yingbin Road?"

The incident took place at the intersection of Binzhou Road and Yingbin Road. Wu Kaiyue divided several teams into two directions. One direction was along Binzhou Road to thoroughly check all surveillance videos.

In the other direction, follow Yingbin Road and check all the surveillance videos.

"Nothing was found on Yingbin Road. We checked all the nine cameras at 21 and 410 intersections last night. We searched for half an hour before and after the time of the incident, and found no video of the deceased appearing."

Not found, still not found.

Wu Kaiyue let out a foul breath and looked around: "Everyone, talk about it, and talk about what you think."

"Chen Kun, you go first."

Chen Kun snuffed out the cigarette butt in his hand: "I'm in charge of technology. I strengthened some of the unclear videos yesterday."

"But there is still no picture of the deceased appearing."

"I think there is nothing wrong with our inspection here. The other party did not appear in the surveillance. It should not be that we missed the inspection, but that the other party did not appear in the surveillance."

"Yes, I agree with Old Chen."

It was a team leader who expressed his opinion: "The way the other party appears at the intersection is not necessarily on foot, but also by car."

"There is relatively little traffic at the intersection where the incident occurred, and no witnesses have been found so far."

"So, I think we can start to investigate the vehicles passing through this intersection during the time period when the incident occurred. Maybe there is no discovery."

Of course, Wu Kaiyue also thought of this point.

In fact, if you want to determine how the victim appeared, you only need to check the surveillance video closest to the intersection of Binzhou Road and Yingbin Road to see if there is any figure of the target.

Expanding the scope is just in case.

"What about other people's opinions?"

You look at me, I look at you.

After staying up all night, they have become panda eyes now, and the target did not appear in the surveillance.

As for the investigation of vehicles, it is not a matter of map investigation.

"Okay, I'll report to Team Qin."

Wu Kaiyue feels that the presence of the Graphic Investigation Team seems to be getting weaker and weaker recently.

In previous cases, most of the direct clues were given by Tuzhen.

As a result, it has failed recently, and the current survey is obviously more prominent than the other aspects.

Taking a deep breath, Wu Kaiyue called Qin Yong.

"Captain Qin, it's me, Xiao Wu..."

The results reported by Wu Kaiyue did not exceed Qin Yong's expectations.

He had already prepared a plan in this regard. The murderer's method of killing Sun Hao was so secretive, how could he not consider the existence of surveillance cameras.

Therefore, the vehicle inspection work has already begun.

An hour before the incident, all vehicles passing through the intersection had been found.

Now, Sun Jun and the others are investigating.

However, it is hard to say what can be found in such a large-scale investigation.

Therefore, Qin Yong also arranged a group of Ren Qiang to investigate Sun Hao's social background.

Sun Hao was killed in such a secret way, what is the murderer's motive?
In addition, Sun Hao has indoleamine substances in his body, which are not available to ordinary people.

Whether this has something to do with the other party's occupation.

doctor?

Pharmacist?

How could Sun Hao have anything to do with these people when he was just an engineer.

It has been 36 hours since the incident happened.

Except for the clear feedback on the results from Tu Scout, the other groups of people have not come back yet.

"Did you see this man yesterday when you were driving at the intersection of Yingbin Road and Binzhou?"

"This... I don't have any impression. I was driving very fast at the time. I caught up with the green light and passed."

A group of Sun Jun is investigating the vehicles that passed the intersection yesterday.

"Head, if you keep checking like this, when will you be a head?"

Sun Jun shook his head, there was no other way.

They have already locked 92 vehicles, and are looking for the owners of these vehicles one by one through the information provided by the traffic police.

However, the other person drove past the intersection and asked if they noticed a pedestrian on the side of the road...

If it's a beautiful woman in particularly cool clothes, maybe some people will still be able to remember her.

A middle-aged man...

"Let's check first. The forensic doctor said that the target's blood contains hallucinogenic substances, which will cause the other party's behavior to be disordered. Maybe someone can have an impression."

Surveying the office now.

"How, is there any result?"

Lao Bai brought tea to Lu Chuan: "It's been more than ten hours of work, do you want to take a break?"

Yes, Lu Chuan has not rested since extracting trace substances from the deceased's shoelaces.

It has been soaking in the underground laboratory for more than ten hours.

After receiving the tea, Lu Chuan turned his head around, and his cervical spine creaked: "It's okay, it's almost over, there are still a dozen bags, and it's almost done after finishing."

Lu Chuan is extracting DNA information from biological materials collected on shoelaces.

Not only is it difficult to collect trace evidence, but the test phase is also very time-consuming.

Now, Lu Chuan has completed most of the work, and there are more than a dozen bags that are almost finished.

"How about the fingerprint analysis up there?"

Lu Chuan was doing experiments below, and he didn't have time to get the fingerprints extracted from the shoelaces yet.

Liu Guodong and the others took it up for appraisal.

Lao Bai shook his head: "Not at all, the fingerprints are too small, not to mention identification analysis, there are only one or two feature points."

"After you finish working here, go up and have a look, we can't figure it out."

Lu Chuan nodded. The fingerprints were collected by him himself. Of course, he knew the difficulty of identifying those fingerprints.

"I'm almost half an hour away, I'll go up right away." (End of this chapter)
