Wu Kaiyue has not slept all night.
As the captain of the graphic reconnaissance team, Wu Kaiyue's work is actually not too busy.
The Scouting Brigade has grown rapidly in recent years, and it lacks neither people nor money.
Although as the captain of the map scout, Wu Kaiyue's job promotion path is not that wide, it is still more than enough.
Ordinary cases are not his turn to pay attention to.
But the traffic accident case that happened yesterday was different. Qin Yong called him personally and made sure to find the complete video of the deceased.
After the superiors gave the order to die, Wu Kaiyue dragged the elite members of the team to work all night, but there was no big gain.
Office of Chen Kun, the top expert of the Pictorial Reconnaissance Team.
Chen Kun is of course the main force in the investigation team for such a big and important case.
At this moment, several group leaders are also in the conference room.
"The first and second groups have checked all 13 intersections and 328 cameras in the direction of Binzhou Road last night."
"The deceased was not found anywhere. According to these surveillances, the other party should not have come from the direction of Binzhou Road. "
The work of reconnaissance is basically to find the needle in the haystack, looking for the few seconds of footage you want to find in the massive surveillance videos. .
"How about this side of Yingbin Road?"
The incident occurred at the intersection of Binzhou Road and Yingbin Road. Wu Kaiyue divided his groups into two directions. One direction was Along Binzhou Road, comprehensively check all surveillance videos.
In the other direction, follow Yingbin Road and check all the surveillance videos.
“Nothing was found on Yingbin Road. There were 419 cameras at 21 intersections. We checked them all last night and checked them half an hour before and after the incident. No video of the deceased was found.”
No video found, still not found.
Wu Kaiyue exhaled a breath and looked around: "Let's talk about it, everyone. Let's talk about whatever ideas we have."
"Chen Kun, you speak first."
Chen Kun put out the cigarette butt in his hand: "I am responsible for the technical aspect. I have enhanced some of the unclear videos yesterday."
"But there is still no scene where the deceased appears."
"I think there is no problem 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."
< br>"Yes, I agree with Lao Chen's opinion."
The person who expressed his opinion was a group leader: "The other party may not appear at the intersection on foot, but may also be in a car."
"There is relatively little traffic at the intersection where the crime occurred, and no witnesses have been found so far."
"So, I think we can start investigating the vehicles passing through this intersection during the time of the crime, and maybe we will find something." Definitely."
Of course Wu Kaiyue also thought of this.
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 are other people's opinions?"
Everyone, look at me and I'll look at you.
After staying up all night, I now have panda eyes, and the target does not appear in the surveillance.
As for investigating vehicles, it is not a matter of visual investigation.
“Okay, I’ll report to Team Qin.”
Wu Kaiyue feels that the existence of the Scout Brigade seems to be getting weaker and weaker recently.
In previous cases, most of the direct clues were given by the detective.
The results have failed recently, and the current survey aspect is obviously more prominent than the other aspects.
Taking a deep breath, Wu Kaiyue dialed Qin Yong's phone number.
"Captain Qin, it's me, Xiao Wu..."
The results reported by Wu Kaiyue did not exceed Qin Yong's expectations. He had already made preparations for this. The murderer's method of killing Sun Hao was so secretive. How could he not take into account the existence of surveillance cameras.
So, the vehicle inspection work has already started.
One hour before the incident, all vehicles passing through the intersection had been found.
Now, Sun Jun and the others are investigating.
However, it is difficult to say what findings can be found from such a large-scale investigation.
So, Qin Yong also arranged for a group of people from Ren Qiang to investigate Sun Hao's social background.
Sun Hao was killed in such a secretive way. What was the murderer’s motive?
In addition, Sun Hao has indoleamine substances in his body, which are not accessible to ordinary people.
Is this related to the other person’s profession?
doctor?
Pharmaceutical staff?
How could Sun Hao, a guy who works in engineering, get involved with these people?
Thirty-six hours have passed since the incident occurred.
Except for the picture scout who has clearly reported the results, several other groups have not returned yet.
"Have you seen this person yesterday when you were driving at the intersection of Yingbin Road and Binzhou?"
"This... I don't have much impression. I was driving very fast at the time. I caught the green light and went over. "
Sun Jun's group is investigating the vehicle that passed the intersection yesterday.
"Boss, if we keep checking like this, when will we be the boss?"
Sun Jun shook his head, there was no other way.
They have 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 party drove by the intersection and asked them if they noticed a pedestrian on the side of the road...
If it were a beautiful woman wearing a particularly cool outfit, someone might still be able to make an impression.
A middle-aged man...
"Let's check first. The forensic doctor said that the target's blood contains hallucinogens, which will cause the other party to behave disorderly. Maybe someone can have an impression."< br>
The current survey office.
"How is it, are there any results?"
Lao Bai brought tea to Lu Chuan: "You have been working for more than ten hours, do you want to take a break?"
< br>Yes, Lu Chuan has not rested since he extracted the trace substances from the deceased's shoelaces.
I have been in the underground laboratory for more than ten hours.
After taking the tea, Lu Chuan turned his head in a circle, his cervical vertebrae crackling: "It's okay, it's almost done, there are still a dozen bags left, we'll be done with it."
Lu Chuan collected the items on the pair of shoelaces. DNA information is extracted from the obtained biological materials.
Not only is it difficult to collect trace physical evidence, the testing phase is also very time-consuming.
Now, Lu Chuan has completed most of it, and there are still a dozen bags left that are almost finished.
“How’s 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.
Old Bai shook his head: "That's not possible at all. The fingerprints are too small. Let alone identification and analysis, there are only one or two characteristic points."
"You can finish this later. Come on, go up and take a look, we can't figure it out."
Lu Chuan nodded. He collected the fingerprints himself, so of course he knew how difficult it was to identify them.
"I've got half an hour left, I'll be up soon." (End of Chapter)
