Chapter 1306: Norms

Changyang Prison.

On the huge, ten-meter-long gate stone, the four sauce-red characters were eye-catching, dignified, profound, and daunting.

Only the telescopic gate on the outermost circle made the majesty of the gate stone next to it greatly reduced. If you don't look at the text content, it feels like the gate of a school.

In fact, the gate of Changyang Prison is not even as high as the gate of Changyang Vocational School of Technology. It is just a very ordinary telescopic gate, painted with white paint. When a car needs to enter or exit, it shrinks, and when it's gone, it expands. The height is only 1.5 meters. Anyone with a certain athletic ability can climb over this gate.

Because it is a low telescopic gate, looking in from the roadside outside the prison, the environment inside Changyang Prison, at least the external environment, is so clearly open.

This is composed of a main road, with greening in the middle, extending straight for a long distance in a flat area. On both sides of the main road, which is as wide as six lanes, are low buildings. Only further inside are gray high walls, intercepting the prison area.

The prison warden had been waiting outside for a long time. Seeing the motorcade of Jiang Yuan and others, while letting people open the gate, he greeted them enthusiastically.

Yu Wenshu, who was accompanying him, hurriedly got out of the car. Everyone is not in the same system. At this time, being polite is still very necessary.

Jiang Yuan and Huang Qiangmin also got out of the car and greeted a group of people opposite.

What the prison warden brought was not only many administrative personnel of his own, but also departments such as the procuratorate waiting on the side.

For the prison, the procuratorate has always been a sword hanging over their heads. Regarding various behaviors, various operations, and countless accidents in the prison, there are clear regulations, most of which are handled by the procuratorate.

It is like if an unexpected death occurs to a prisoner, there is a regulation that the direct management personnel must arrive at the scene within 3 minutes. If they don't arrive on time, they are suspected of dereliction of duty and can be sentenced to 3 years in court.

Of course, if it is indeed an accidental death, or suicide, etc., and the direct management personnel arrived at the scene according to the regulations and handled it according to the regulations, at most, they will be fined bonuses, and the sub-prison warden, prison warden, and even the prison warden above can save a disciplinary action.

The situation of a homicide case is naturally more complicated.

"This is Lin Qingyun, Prosecutor Lin." After the prison warden shook hands with Jiang Yuan, he immediately introduced the prosecutor next to him, and added: "Next, I will trouble Director Jiang to cooperate with Prosecutor Lin. I have to avoid suspicion. Of course, if you have any requirements, I will listen to the command."

He didn't speak very smoothly, and it was indeed a bit difficult.

For the prison, the death of a prisoner is almost the most troublesome type of situation.

Huang Qiangmin didn't wait for Jiang Yuan to speak, stood out first, and said: "We are just here to help, help within our power. At present, let's look at the surveillance first?"

Prosecutor Lin Qingyun nodded solemnly: "We have been watching the surveillance for the past two days, um, let's watch it and then talk..."

Jiang Yuan and Huang Qiangmin looked at each other, slightly relaxed.

Liu Jinghui rubbed his hands silently, as if he had smelled a delicious green fly.

Whether surveillance can be seen is a watershed for this case.

In the current prison, especially in the last ten years, domestic prisons have achieved full coverage. Professional personnel install professional cameras, ensuring to cover every corner of the prison, which in terms of hardware, first eliminates the existence of surveillance blind spots.

If everything is done according to norms, everything the prisoner does in the prison is under surveillance, including going to the toilet and taking a shower, and naturally including the death process of a prisoner.

If this is a premeditated murder, and a premeditated murder that escaped the routine review of the procuratorate, it can also be called a locked-room murder.

The locked-room murder of the new era is still a locked-room murder displayed before everyone's eyes!

A group of people took the prison car and soon arrived at the office building.

In the process of walking inside, prison police officers coming and going would intentionally or unintentionally observe Jiang Yuan and others.

Liu Jinghui and Jiang Yuan would also observe the other party.

Changyang Prison normally detains more than 4,000 prisoners, corresponding to more than 600 staff members. Regardless of which number, it is not simple for criminal investigation.

In addition to extremely strict management, the scale and operation mode of a prison are no different from a large factory or mine. In fact, the scale of industries in the prison is not small. For example, Changyang Prison has a copper coil factory and its own cattle farm, strictly implementing an 8-hour working system every day.

In the past, many prisons had three shifts. Later, the difference-based appropriation was changed to full appropriation, and after the prison enterprise's income was fully handed over, the prison's production enthusiasm was gone.

Now, prison and enterprise are separated. Changyang Prison also independently established a group company. The general manager of the company is equivalent to the prison warden, and they are also police officers, which is also a relatively special existence.

The atmosphere in the prison inevitably affected Jiang Yuan and others.

Everyone walked into the surveillance duty room in silence, and saw screens all over the wall, and a separate area composed of a small screen in the depth.

"We have been watching the surveillance here for the past two days." Lin Qingyun explained, and added: "After watching today, we have to take some hard drives back."

"Then let's look at the situation at the scene first, the surveillance of the deceased falling to the ground." Jiang Yuan didn't care about so much, anyway, he had to see the surveillance first.

A prison police officer didn't say a word, stepped forward, waited for a while, and then released the surveillance.

The scene of the deceased falling to the ground in the cafeteria had long been carefully checked. At this time, it was released, directly multi-angle shots of the nine-grid, including a panoramic shot of the cafeteria from front to back, a panoramic shot of the cafeteria from back to front, as well as one facing the case table, one facing the door, and a camera in the next room when the incident happened.

Jiang Yuan has LV3 technical defense surveillance technology. He can see that these surveillance locations are arranged according to norms, and the selected surveillance is also carefully selected, and there is no perfunctory component.

Of course, the selection of surveillance is only one aspect, specifically the content of the surveillance...

You can see the deceased was originally kneading dough, suddenly clutching his stomach, stumbling and falling on the floor.

Immediately after, the cellmate who worked in the cafeteria together shouted, and then a middle-aged man in prison uniform ran over quickly, shouted at the deceased twice, and then ran to call a police officer over.

The police officer came over and asked a sentence, then started to call with a walkie-talkie, and then started to perform cardiopulmonary resuscitation on the prisoner who fell to the ground.

The whole process went very quickly. Although the cafeteria was in a mess, it could still maintain roughly the same order.

The prison police officer who released the surveillance introduced at this time: "The first one who shouted was the supervision post. It is the user we selected. The daily performance is very good. The police officer he called over is the direct management personnel of the group, Wang Zhai..."

He roughly introduced the characters appearing in the environment, and then closed his mouth.

"What do you think?" Prosecutor Lin Qingyun asked impatiently.

"Looking at it like this, was poison used? I have to go back and do an autopsy before I can be sure." Jiang Yuan frowned slightly.

Investigating poisoning is actually not easy. What is difficult is not solving the case, but determining the type of poison, especially some cold biological toxins. If you check blindly, you might not be able to find it in a lifetime.

Liu Jinghui gave an "Hmm" and said: "Looking at the whole video, there is nothing to say. Only this part of saving people, several cameras, all filmed the backs of the prisoners. Whether they took this opportunity to do something is not certain." ===== CHAPTER 1307 =====
