The crackdown on organized crime began with the arrest of the mother-in-law.

Chapter 673 Identity Confirmed, A Familiar Taste

Qin Chuan did not stay at the scene for long; the High-tech Zone Criminal Investigation Brigade was in charge, so there was no major problem.

There are strict procedures for handling crime scenes in such criminal cases.

For example, conducting on-site investigations and taking photos.

On-site investigation and photography are required, and different sites have different needs. Currently, this site is a relatively typical indoor site.

First, take wide-angle photos, then medium-angle photos, and finally close-up photos. All photos must be numbered.

In addition, depending on the specific situation of the object, such as comparing the correction position of the skin with the space of other areas, detailed photos also need to be taken.

The time spent on-site investigation and photography is not just a matter of taking a few photos and finishing in a few minutes; it often lasts for an hour, two hours, or even longer.

Because it's impossible to completely reproduce the original size of an object during the photo-taking process, a scale bar is sometimes needed when viewing photos online.

This is why sometimes in movies or TV series, you see photos of crime scene investigations with a 10-centimeter or 20-centimeter ruler next to them. This comparison allows viewers to intuitively understand the size of the objects photographed during the crime scene investigation.

In addition, the spatial orientation required for on-site survey photography differs from that of general photography.

In addition to on-site investigation and photography, there are also strict procedures for forensic doctors to enter the site.

Generally, the investigation of criminal cases begins with on-site investigation, where criminal police officers enter first to complete the on-site investigation and take photos, and then forensic doctors enter the scene.

There is only one reason for a forensic doctor to be present: to examine the body, which is commonly known as an autopsy.

The full name of an autopsy is forensic autopsy.

Generally, at the crime scene, forensic doctors will conduct a preliminary examination of the body's surface. However, under normal circumstances, this preliminary examination cannot completely determine the cause of death and the time of death.

If there are any doubts, a further autopsy will be performed, which is often referred to as a post-mortem examination.

However, an autopsy doesn't necessarily mean shooting the body three times, cutting it into pieces, and then putting everything back together.

Sometimes only local examinations and pathological analyses are needed.

In addition, the consent of the deceased's family must be obtained before an autopsy can be performed.

When there are doubts about the cause of death and an autopsy is required, the police will consult the deceased's family.

If the other party does not agree, the police generally cannot force the practice, but this does not apply to criminal cases.

In criminal cases, the police have the right to conduct an autopsy, even if the deceased's family does not consent to it.

However, in this case, relevant personnel from the procuratorate and third-party citizens unrelated to the case are required to witness the proceedings.

Qin Chuan had studied these procedures when he was in school, but to be honest, he didn't have a very thorough grasp of them. After participating in case handling for the past year, he basically forgot them because he wasn't actually doing related work.

The on-site investigation is underway, and forensic experts have begun their inspection of the factory. The investigation results from the school are also being processed.

Soon, a morning had passed, and Qin Chuan held the first case analysis meeting at the High-tech Zone Branch.

The deputy director in charge of criminal investigation at the High-tech Zone Branch, as well as the director, were both present.

"Director Qin, let me report on the basic facts of the case."

Zhang Qiang and his team gained a relatively detailed understanding of the crime scene after a morning of work.

"First and foremost, we identified the deceased this morning."

Zhang Qiang gestured to his assistant to operate the projector, which displayed a half-body photo of a man.

"Gao Yunfeng, male, 18 years old, a local of Linzhou City, is a sophomore majoring in international finance at the School of Economics and Management of Linzhou University."
