National Forensic Doctor

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 created homogeneous object is too easy. In fact, ground-penetrating radar is used to detect road defects in engineering, which means that you don’t need to hide anything underground, you can find any cracks or the like.

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 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 cheerful. He kept Li Yujing here just to let his mood fluctuate. Otherwise, it would be more difficult for a noble young master like this who has inherited a large amount of family property to have too many unrealistic expectations and get a direct result 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 looked back at the laptop on the trolley, and then ordered: "Video, take pictures, detect the light, take the traces and then smash the wall."

As his order was issued, 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 can easily leave marks. Several technicians happily turned on the survey lights and changed the light source to take pictures. After taking the photos, use various electrostatic adsorbers, flat footprint extractors, etc. to remove the traces that can be removed.

This step was also carried out because of Jiang Yuan's request. After all, a destructive operation was required. Otherwise, ordinary trace extraction would not be comprehensive to this extent. The workload is too heavy. For ordinary cases, not to mention that the staffing level cannot reach this level. Even moving equipment would exhaust a few people to death.

After all the preparations were done 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 whispered.

The technicians who were planing the wall didn't even ask a question, 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 at all. Just follow the standard procedures. It's just a purely physical job.

Compared with smashing the wall, digging the ground took a little less time. It wasn't until there was a "ding" from below that the two technicians stopped.

As seen by 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 the decoration.

Several people looked at Li Yujing with interest.

Li Yujing is also 40 years old, but his complexion has deteriorated beyond recognition. At this moment, you can't even tell whether his mood has become worse, or particularly bad, or 12% bad, super bad, or extremely bad...

But Li Yujing still has an IQ. I don’t know if he has done it before. He probably has some training over the 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 Me. You were invited by my brother, that stupid guy is bad at doing things and has a way of hurting people."

"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 in the ground. 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 you to Captain Jiang, who is the top trace inspection expert in our country. When you buried the box, did you wear gloves throughout the process? When you bought the box? When you transported the box?"

Li Yujing was completely speechless.

He himself was not a very cautious person. He was lucky enough to remember to wear gloves at critical moments, and he did not consider the option of wearing gloves throughout the process.

On the other hand, wearing gloves throughout the process itself was too strange.

Jiang Yuan leaned over the iron box and began to extract fingerprints.

This kind of box placed in concrete must have a huge loss of fingerprints. Even Jiang Yuan needs to be extra careful and attentive.

"Take the person back." Captain Hao felt that the demonstration to Li Yujing was enough. As for what was opened in the box, Li Yujing himself should know better than them.

Two criminal police officers took Li Yujing away.

Li Yujing, with long hair, shook his head, as if he wanted to resist, but he was pinched before he could even exert force.

The criminal police of the criminal police detachment did not handle many cases, but it was still very easy to catch a second-generation.

Jiang Yuan took fingerprints and other traces, then took the iron box to the side, laid a plastic sheet, and then opened it under the camera.

When he saw it, he saw a blue-faced Patek Philippe, staying inside.

…

Lanyue City Criminal Police Detachment.

A young man "clicked" on the keyboard, constantly adjusting the font size, and finally put it on the big screen behind him when he was satisfied.

"Dai Zhi, do you think this font and color are okay?" The young man asked Dai Mingsheng modestly.

"One size bigger, adjust it to the middle." Dai Mingsheng nodded.

The young man smiled and put the final format that he had prepared long ago on it - the big words "Li Yaoji murder case scene meeting" appeared in bold on the projection screen of the conference room.

Dai Mingsheng nodded with satisfaction, then turned to his subordinates and said, "I don't need to say much about the importance of Li Yaoji's murder case. Next, after Jiang Yuan and the others have made preliminary preparations, we will hold an on-site meeting to discuss the resources and personnel arrangements needed. All teams must be notified and come to the on-site meeting. One reason is to participate in the investigation and brainstorm. The other is to express their opinions!"
