The ground-penetrating radar that Tang Jia brought back was just a cart, with the main unit of the radar underneath and a laptop on top, connected by a hard tube in the middle. In terms of appearance, it was actually not as good as the engineer mine detector in the movie.
But it is already the equipment of the new era. The thick box integrates the transmitting unit and the receiving unit. What is transmitted and received are electromagnetic waves. Although the upper laptop is just an ordinary laptop, after installing the supporting software
, which can basically display the underground situation synthetically.
The technicians from Ningtai County pushed it around the villa and found out everything hidden under the ground and in the walls.
For ground-penetrating radar, the field environment is still a little challenging, and this artificially manufactured homogeneous object is too easy. In fact, ground-penetrating radar is used for road defect detection in engineering, which means that it is not necessary at all.
Whatever is hidden underground, in some crack or something, you can find it.
However, this slightly new equipment is a bit unfamiliar to ordinary people, so when the ground-penetrating radar stopped behind Li Yujing, his mind was filled with all kinds of doubts.
He doesn't understand technology.
Human nature, he felt he understood.
Li Yujing turned his head hard, trying to see who was betraying him.
Captain Hao was happy. He kept Li Yujing here just to let his mood fluctuate. Otherwise, this kind of noble young master who has inherited a large amount of family property has too many unrealistic expectations, which is relatively unreasonable.
It is difficult to get the result directly from the interrogation.
Liu Jinghui came up from behind, and when he saw this, he just glanced at Captain Hao without saying a word, and secretly labeled Captain Hao: scheming.
Jiang Yuan turned back and glanced at the laptop on the trolley, then ordered: "Video, take pictures, detect the light, take the traces and then smash the wall."
Following his order, a team of technicians filed in and began to remove fingerprints and other traces from the wall under the camera's full recording.
Li Yujing's large villa is luxuriously decorated, and the walls are all covered with wainscoting, which is a material that is easy to leave marks. Several technicians happily turned on the inspection lights and changed the light source to take pictures. After taking the pictures, they used them again
Various electrostatic adsorbers, flat footprint extractors and the like can be used to remove traces that can be retrieved.
This step was also carried out because of Jiang Yuan's request. After all, it is a destructive operation. Otherwise, ordinary trace extraction will not be comprehensive to this extent. The workload is too large, and ordinary cases, let alone the staffing, cannot reach this level.
At such a level, moving equipment would exhaust a few people to death.
After all the preparations were completed and tarpaulin was spread on the ground, the police happened to come up with a sledgehammer and a newly purchased impact drill.
Chug tug tug...
80,80…
When everything calmed down, they saw that the walls of the villa had been smashed into pieces.
Captain Hao and others stretched their necks to look over, frowning.
After waiting for a while, Captain Hao came to Jiang Yuan and asked, "Can't you find it?"
"Under the wall." Jiang Yuan babbled.
The technicians who were planing the wall didn't even ask, so they went up with the impact drill.
The positioning of ground penetrating radar is extremely accurate. For technicians who can see and see, there is basically no secret. Just follow the standard operation. It is a purely physical job.
Compared with smashing the wall, digging the ground took a shorter time. It wasn't until there was a "ding" from below that the two technicians stopped.
As seen from the ground-penetrating radar, there is an iron box below the ground, which is entirely embedded in the cement of the floor. It must have been inserted during decoration.
Several people looked at Li Yujing with great interest.
Li Yujing is also 40 years old, but his face has deteriorated beyond recognition. At this moment, you can't even tell whether his mood has become worse, extremely bad, extremely bad, super bad, or still
Extremely bad...
But Li Yujing still has an IQ. I don’t know if he has done it before. He has probably been trained a lot in recent years. I heard him snort twice and said: "I know what you want to do, you just want to frame me and put the blame on
I, you guys were invited by my brother, right? That stupid guy is not good at doing things and has a way of harming others."
"This is your house, and you decorated it yourself." Captain Hao looked at Li Yujing and laughed, and said, "If you want to accuse someone of frame-up, you'd better find some suitable evidence."
"You have no evidence to prove that I buried it!" Li Yujing naturally didn't want to admit it.
"You really need to talk to your lawyer about the burden of proof." Captain Hao paused for a moment, and then said in a serious tone: "You are not what we want in the iron box buried underground.
Bar?"
He won't name the specific stolen goods,
Li Yujing was about to answer, then stopped and said, "How do I know what you want? You just want to put the blame on me."
"You damn duck has a tough mouth." Captain Hao prepared to overwhelm him with his momentum.
At this time, Jiang Yuan opened his mouth to direct the technicians, saying: "Camera. I'll take the fingerprints."
Captain Hao immediately looked at Li Yujing next to him, and was not surprised to see his expression change drastically.
Captain Hao felt very comfortable. Jiang Yuan fully understood his purpose of keeping Li Yujing. This kind of cooperation was excellent.
Liu Jinghui looked at this scene with pride and helplessness.
To ordinary people, the dragon is a powerful and mysterious existence. Every move of the dragon will naturally cause ordinary people or ordinary knights to exclaim.
Captain Hao turned to Li Yujing and smiled, saying: "Let me introduce to you, Captain Jiang is the top expert in trace inspection in our country. When you buried the box, did you wear gloves at all times? What about when you bought the box?
?What about when shipping boxes?”
Li Yujing was completely speechless.
He is not a very cautious person, so it would be nice if he could remember to wear gloves at critical moments. He did not consider the option of wearing gloves at all.
But on the other hand, wearing gloves the whole time is just too weird.
Jiang Yuan leaned over the iron box and began to extract fingerprints.
This kind of box placed in concrete will definitely cause great damage to fingerprints. Even Jiang Yuan needs to be extra careful and attentive.
"Take the person back." Captain Hao felt that the demonstration given to Li Yujing was enough. As for what was in the box, Li Yujing himself knew better than they should.
Two criminal police officers escorted Li Yujing away.
The long-haired Li Yujing shook his head, as if he wanted to resist, but was pinched before he could exert any force.
The criminal policemen of the criminal police detachment don't handle many cases, but it's still extremely easy to deal with a second-generation criminal.
Jiang Yuan took fingerprints and other traces, then took the iron box to the side, covered it with plastic sheeting, and then opened it under the camera.
Upon entering, you will see a blue-faced Patek Philippe, staying well inside.
…
Lanyue City Criminal Police Detachment.
A young man was typing on the keyboard, constantly adjusting the font size. Finally, when he was satisfied, he put it on the big screen behind him.
"Dai Zhi, do you think this font and color are okay?" the young man asked Dai Mingsheng humbly.
"Size up one size and adjust it to the middle." Dai Mingsheng nodded.
The young man smiled and put up the final format that he had prepared long ago - "On-site meeting to solve the murder case of Li Yaoji" appeared in bold letters on the projection screen in the conference room.
Dai Mingsheng nodded with satisfaction, then turned to his subordinates and said: "I don't need to explain the importance of Li Yaoji's murder case. Next, after Jiang Yuan and the others have made preliminary preparations, we will open a scene first.
We will hold a meeting to discuss the resources needed and the personnel arrangements that need to be made. Each team must be notified, and they will all come to the scene to solve the case. One is to participate in the investigation and brainstorming, and the other is to express their position!"
