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

Chapter 530 Follow the clues

While in the detention center, Qin Chuan had already checked the surveillance footage and questioned the guards.

It is now almost certain that Qian Youcai's son did indeed die from an acute heart attack, and the attack occurred in a very short time; less than a minute passed between when the police noticed something was wrong and when he died.

But that's utter nonsense. Although Qin Chuan himself wasn't a medical student, he did have forensic-related skills.

Even if a person's heart is pierced by a bullet, they will survive for less than a minute. What kind of heart disease could kill Qian Youcai within a minute?

The key point is that the forensic examination results also indicate that the cause of death was myocardial infarction.

The forensic doctor stated that Qian Youcai had a pre-existing heart condition, which led to a myocardial infarction. It happened very quickly; he likely had a history of this illness. Therefore, his death from the acute myocardial infarction was extremely rapid, occurring within a minute.

Qin Chuan possesses relevant forensic skills as a reward from the system.

He knew very well that in the acute phase of a myocardial infarction, limb convulsions and foaming at the mouth would usually occur, and in such cases, without further treatment, death would generally occur within two to three minutes.

Moreover, people who die from myocardial infarction have relatively obvious external physical characteristics, such as pale complexion but purplish lips.

A corpse will become stiff after death.

Qian Youcai's body did indeed fit these characteristics. From Qin Chuan's professional perspective, he did indeed die from a myocardial infarction.

In other words, the forensic examination was without fault.

What Qin Chuan found most interesting were some clues discovered in the surveillance footage.

At first, Qian Youcai was locked in this room alone. Later, two other prisoners who had been fighting were also locked in this room.

After being locked inside, the other party and Qian Youcai did not have any direct physical contact; all three of them remained quietly in their respective positions.

In other words, based on the surveillance footage, these two prisoners were definitely not related to Qian Youcai's death, since they had never even been in contact with each other.

However, if there is any connection, it is that when Cai Da fell ill, these two prisoners did not step forward to help, nor did they even tell the police.

The two of them only got sick because they saw money.

Isn't this strange?

Qian Youcai's death was definitely not as simple as a natural death.

If Qin Chuan believes this, then his operation, or rather, his battle, has failed.

So how do we find out the reason for the previous murders? Who is the murderer? By following the clues, we can uncover the real culprit who invaded modern times.

As for the murderer?

If it were someone else, it might be impossible to find the murderer. Even if you suspect the two culprits, there's no evidence.

But Qin Chuan was different; he had the Eye of Sin, and he could tell what was going on just by scanning the heads of the two prisoners.

Even when he first entered the detention center, he had already looked at everyone he passed with evil eyes.

This is a typical case of collusion between insiders and outsiders that led to Qian Youcai's death!

The two prisoners directly targeted were those detained in Qian Youcai Prison. However, because these two had been in the detention center for a long time, they had been taught the methods and techniques used, and there was collusion between internal police officers and outsiders.

The entire criminal process was completely transparent to Qin Chuan.

Chen Guobao, male, 32 years old, with a crime value of 132, previously served 3 years in prison for robbery and intentional injury.

Two hours earlier, he used tococaine to induce a heart attack in Qian Youcai, resulting in his death.

Among the other two prisoners who were being held with their relatives and friends, one of the short men was named Chen Guobao, who was the one who directly committed the crime.

In the eyes of evil, Chen Guobao's criminal acts were laid bare.

At the same time that Qian Youcai was detained in the detention center, someone from Chen Guobao's side came to visit him.

Someone offered him a million to do this; he's destined to be rich but not rich.

There were two police officers assisting him inside the detention center.
