Forensic Doctor 2003: I Became a Legend on the Front Lines of Criminal Investigation

As they were talking, the police officer on duty at the police station handed over a stack of medical records: "Look, the deceased, Li Genfu, was 70 years old this year. He was diagnosed with lung cancer six months ago, and it has now progressed to the late stage of lung cancer."

Li Jian took the medical record and began to read it.

At this moment, Jiang Chen put the on-site investigation kit in his hand aside.

He had only glanced at the body, but he already knew the key points of the forensic examination at the scene.

For forensic doctors, if a corpse does not require an autopsy, only a surface examination is needed.

Of course, the purpose of a physical examination is mainly to see if there is any possibility of a criminal case.

For corpses found in criminal cases, an autopsy is mandatory.

In theory, every corpse should, in principle, undergo an autopsy.

The purpose of an autopsy is to determine the cause of death.

Although external injuries are visible, internal poisoning is not.

Poisoning cannot be seen directly; the only way to detect it is through autopsy, which involves examining the stomach contents of the deceased to see if there are any signs of poisoning.

Later, many forensic doctors stopped performing autopsies on many corpses in order to save time and effort.

One very important reason is that many people in China are quite averse to autopsies.

After all, everyone hopes to be left with a complete body after death.

Therefore, the requirements for forensic scene investigation are particularly high.

For example, if you determine that the body in front of you died by hanging, then this case will never be brought up again.

The body will soon be buried in the ground, or even cremated.

Even if someone were to reopen this case years later, the lack of an autopsy would prevent the determination of the cause of death, thus hindering prosecution and investigation.

Even if the murderer has a change of heart years later and admits that he poisoned the victim, the law can't do anything about it and can only watch helplessly as he goes free.

Because the forensic doctor's judgment determines the direction of the case.

If you say it was suicide, then proceed as if it were suicide. The family will handle the body, and the criminal investigation team will call it a day.

If you say it was murder, then the body needs to be autopsied, the criminal investigation team needs to conduct an investigation, and they'll be working overtime all night.

Of course, we can't get the result wrong either. If we do, it will cause many people to work overtime for no reason, and the case will eventually become an unsolved mystery.

You should know that once a case is filed, it's not easy to withdraw it.

If a suicide case is eventually turned into a homicide, then there is no murderer, and the case will never be solved.

Even if it becomes a cold case, it will never be solved.

Therefore, those who conduct on-site investigations at crime scenes, especially forensic doctors, face the greatest pressure.

At this moment, Jiang Chen had already put on gloves.

Even for a physical examination, he still wore double gloves.

After all, anyone who looks healthy can have infectious diseases, especially the elderly.

Of course, in this reborn era, Phoenix Legend's songs are not yet popular, they have not yet resounded in every corner of the city, and there is no ballroom dancing for the elderly.

However, it cannot be ruled out that some elderly people may have special habits, and they may even contract highly infectious diseases while receiving blood transfusions during hospitalization.

After putting on his gloves, Jiang Chen stood up and turned to look at Li Jian: "Captain Li, I'm going to examine the deceased's body now."

Li Jian shifted his gaze from the medical record and said, "Just handle it at your own pace. I'll check on the surrounding situation."

As he spoke, he turned to look at the police officers at the police station and said, "Arrange for someone to provide lighting for our technicians so they can see more clearly."

"Okay." The officer on duty immediately instructed the auxiliary police officer next to him to shine a flashlight.

At this moment, Jiang Chen bent down and began to examine the body.

Elderly patients with advanced lung cancer often experience debilitating physical changes.

He was extremely thin, with almost all of his muscles gone; he was practically skin and bones.

There was a ligature mark on the neck. Jiang Chen then lifted the victim's chin to fully expose the ligature groove and carefully observed its edge.

He observed for a long time but did not see any bleeding.

It's important to know that people who hang themselves will bleed around the ditch.

However, because the elderly person's skin is relatively loose and the local blood vessels are very thin, even if there is no bleeding, it cannot be concluded that they were hung after death.

Next, he focused on observing the direction of the cableway.

If someone strangled someone and then hung them up, then two rope grooves would be formed, one of which would be parallel.

After all, the most effective way to strangle someone to death is to pull them horizontally, similar to how you trap a white wolf in the north.

However, if you are using a suspension system, its direction is upward.

Under the bright lights, Jiang Chen carefully observed the condition of the cableway.

There is only one groove around the entire neck, which is U-shaped and lifts upwards.

Then, he gestured to Wang Hui next to him to take a picture of Suogou.

After snapping photos, Jiang Chen immediately examined the other parts of the body.

For bodies that died by hanging, asphyxiation is the clear cause of death.

Asphyxiation can result in dark red livor mortis and conjunctival hemorrhages.

Of course, if an autopsy were performed, one would certainly see numerous pinpoint hemorrhages on the surface of the heart and lungs.

However, no autopsy was performed at the moment; we could only examine the conjunctiva of the eyelids to see if there were any pinpoint hemorrhages.

Next, Jiang Chen pried open the deceased's left eye to examine it, revealing the whites of the eye and the conjunctiva of the upper and lower eyelids.

Despite his strong efforts in prying it open, unfortunately, no pinpoint bleeding was observed.

He quickly changed his position, squatted down, and forcefully pried open the eyes, almost prying the deceased's eyeballs out, but still couldn't see anything.

At this moment, Jiang Chen felt a little uneasy.

Could there be something wrong with this corpse...?

Next, he pried open the deceased's right eyelid.

Using the same method, the eyelids were pried open to expose the deceased's eyeballs, but no pinpoint bleeding could be seen.

At this moment, Jiang Chen suddenly became alert.

Next, he examined the deceased's lips again, and there were no signs of oxygen deficiency such as cyanosis.

At this moment, Jiang Chen's mind was filled with images of the changes in lividity in hanged individuals.

According to the formation mechanism of livor mortis, it is formed by the accumulation of blood in the blood vessels.

For a hanged corpse, because the body is suspended, the blood falls down and accumulates in the lower limbs, so livor mortis will definitely appear on the lower limbs.

However, when he turned the deceased over from a supine to a prone position, he suddenly discovered a large area of ​​livor mortis on the back, and the area of ​​livor mortis was so large that it had merged into patches...
