Serious Crime Unit 1

Chapter 790 The Death of the Judge (4)
Jiang Yiming drove to the Public Security Department. The Public Security Department is located in the southwest of Jiangdong District, diagonally opposite to the Municipal Bureau. The straight-line distance is 20 kilometers and the driving distance is about 25 kilometers. There was no traffic jam on the road. Half an hour later, Jiang Yiming drove the car into the underground of the Public Security Department. Parking lot and then walk out of the parking lot.

The Public Security Department is a 38-story building. The main building is majestic and majestic. The five-star red flag flutters in the wind on the roof. The light blue glass curtain wall shines in the afternoon sun. There are 12 marble steps in front of the building, which set off the building. Be more majestic and spectacular.

Jiang Yiming hasn't been to the Public Security Department for almost half a year, but he is very familiar with it. He knows what each floor is used for and what leaders work in which offices.There are six deputy directors in the Public Security Department, and they all work on the 6th floor. Guo Zhicheng is in charge of criminal investigation, so Jiang Yiming has the most contact with him.

He took the elevator to the 38th floor. After getting off the elevator, he walked through the corridor and came to Guo Zhicheng's office. He gently rang the doorbell and then quickly let go of his finger, because Guo Zhicheng could see the screen on the wall opposite his seat. to see who the visitor is.

Guo Zhicheng saw Jiang Yiming outside the door and used the remote control on his desk to open the door and let Jiang Yiming in.After Jiang Yiming entered, Guo Zhicheng motioned him to sit down on the chair opposite. Jiang Yiming gave him a military salute and then sat down.

"Captain Jiang, Director Fang has already reported the specific case to me. Because the two deceased persons who were killed had special identities, I just remembered that I haven't seen you for a long time, and I am free today, so I called you here. What happened? This is a special case, I still want to ask, when can you solve the case?" Guo Zhicheng is gentle but serious. He is only 52 years old. He has taken this position at such a young age. His ability is extraordinary.

"This... I think the case can be solved within a month or two." This question is very difficult to answer. Even the Minister of Public Security cannot answer it, because no one knows how long it will take to solve the case. However, Jiang Yiming relied on the speed of solving cases in the past. answered.

"What I'm worried about is what if there is another shooting case?" In fact, Guo Zhicheng doesn't want to know the exact time of solving the case, but is afraid that the murderer will continue to kill.

"Judging from the current situation, this kind of thing should not happen again."

"Why do you say that?" He moved his eyes from the table to Jiang Yiming's face.

"Because today we have found the murder gun left behind by the murderer, which is the Barrett sniper rifle that killed people. Therefore, we all believe that the murderer has completed the murder mission and the possibility of another shooting murder is very small."

"Oh, I didn't hear Director Fang say this. Why did the murderer leave the murderous gun to us?"

"I'm sorry, I haven't reported it to the Bureau in time, so the Bureau doesn't know... I can't figure it out either, but after comparing the bullet marks, the bullets that killed Tang Mingshi and Fang Weihai were indeed fired from that gun .”

Guo Zhicheng's expression softened: "Actually, I'm not putting pressure on you. The two deceased are about the same age as me and have worked together before. Their families also called me, hoping that I can urge you to solve the case as soon as possible. I It would be nice to have an explanation for the family of the deceased."

"Well, I know it's not easy for you to be a leader. Fortunately, these two cases were not exposed by the media, otherwise the pressure on you and us would be even greater."

Guo Zhicheng nodded: "I trust your ability very much. We will talk about this today. In 10 minutes, experts from the neighboring provincial public security department will come to discuss the case with me. Young man, do your best. I am optimistic about you. If you If you have any difficulties, you can call me at any time and I will do my best to help you.”

"Thank you, Director Guo!" Jiang Yiming stood up and saluted Guo Zhicheng again, then turned and walked out of the office.He felt a little relieved. After all, Guo Zhicheng did not put a lot of pressure on him. Of course, it was not that he did not give it, but he gave it tactfully and easily, and at the same time he was encouraged. A good leader will not make promises to his subordinates easily. Once he makes a promise, he must Keep your promises or you will break your promises.

When Jiang Yiming returned to the criminal police team, Lu Yingying came to the office to look for him, as if she could see through things.Lu Yingying said: "Captain Jiang, I carefully inspected the sniper rifle and found that the murderer did not shoot and kill Fang Weihai at the sniper site. The sight of the sniper rifle can be connected to the wireless network, and the trigger and gun body have receivers. All All actions can be controlled remotely, including targeting Fang Weihai, and the murderer killed Fang Weihai via remote control online."

"Ah? So advanced? Why does he have to go to such lengths?"

"He must be afraid that we will use Fang Weihai as a bait and capture or kill him when he is about to snipe Fang Weihai, because our city bureau or armed police force has more skilled snipers than him."

"This murderer is so smart. He has considered everything we didn't expect. It's really scary. Can we find his IP address?" Jiang Yiming felt scared.

"The IP address is encrypted using the RSA method, which is currently the most influential and commonly used public key encryption algorithm, and is encrypted with multiple digits and multiple symbols. There is no reliable attack in the world. RSA algorithm. As long as the key length is sufficient, information encrypted with RSA cannot actually be cracked. But today, as distributed computing and quantum computer theories become increasingly mature, the security of RSA encryption has been challenged and questioned. But don't expect me to crack it." "Is the sniper rifle registered?"

"Xiao Ke said no, and it was not found in the integrated ballistic identification system, so the gun should be smuggled."

"It's so clever! It was done without leakage." Jiang Yiming once again praised the murderer.

"Captain Jiang, have you become stupid? Don't you always love to talk about Rocca's Law in front of us? There is no perfect murder in the world!"

Jiang Yiming saw Lu Yingying making faces at him and smiled easily. He had never smiled so easily since the shooting incident.Of course, Lu Yingying teased him like this because she found the sniper rifle.

"I think Tang Mingshi and Fang Weihai were killed by the murderer after jointly handling an unjust case. It is a better way to look for clues in this direction."

"But they have been prosecutors and judges for most of their lives and have handled countless cases. If they investigate based on this clue, how much police force and time will be invested? Besides, restarting the investigation process requires approval from the city procuratorate and the court. If they have handled it All cases must be reopened for investigation, and even one year of the city’s criminal police time is not enough. This is not a good idea,” Jiang Yiming said.

"There is no need to restart investigations in all cases. Let us first draw the line: first, homicide cases that have been sentenced to suspended death, death penalty, or life imprisonment, because suspects who are not in these three situations will generally not retaliate for murder; second, those cases are under appeal and have been continuously Suspected unjust cases that have been appealed for many years but have never been vindicated; third, suspects who have been released from prison and are still appealing. If you grasp these three points, you may have a breakthrough." Wu Jiang answered.

"Yes, this narrows the scope a lot." Liu Xiaowei said that he and Shi Wei both participated in the discussion meeting of the No. 1 Major Crime Team.

"What Lao Wu said makes sense, but we all know that many prison guards use this as a condition to prevent prisoners in murder cases from writing appeals in exchange for the prisoner's sentence being reduced. When the prisoner repeatedly writes appeal materials to no avail, he loses If they lose hope, they will follow the advice of the prison guards and stop appealing. After they are released from prison, they will retaliate against Tang Mingshi and Fang Weihai. In this case, it will be difficult to find the murderer."

"Captain Jiang, the situation you mentioned does exist, but it is rare. I think we still need to investigate the murder case from the prisoner. I don't think there have been more than 30 murder cases in Jiangbei District in the past 300 years, right? And I think that I was murdered. There are fewer unjust cases, so as long as we mobilize all police forces and re-examine the disputed or appealed cases, we will definitely find clues from them," Shi Wei said.

"Why set the deadline within 30 years?"

"We assume that the suspect was unjustly accused in his 20s. He has been in his 50s since he was released from prison. It is impossible for a person in his 50s to be a sniper. Also, Tang Mingshi became the chief prosecutor in 1998. , Fang Weihai also became the president of the court in 2000, so the 30-year limit has been extended for a long time."

"Shi Wei's analysis makes sense. We can go to the Jiangbei Branch to check the files of all homicide cases in the past 30 years. All of our criminal police team are involved in reviewing the files. Including the criminal police from the Jiangbei Branch, there are already more than 300 people involved. Each person can read the files. I think it won’t take long to find clues.” Jiang Yiming agreed.

"We will also send people to visit the Provincial No. [-] Prison to see which homicide cases in custody have been writing complaint materials. This is also a shortcut." Wu Jiang said.

"Okay, let's do it this way. Lao Wu and Xiao Ke will visit the No. [-] Prison in the Province, and I and others will go to the Jiangbei Branch to check the files." Jiang Yiming announced that the meeting was adjourned, and each went to take his own people to the Jiangbei Branch to check the files.

The Provincial No. 32 Prison is located in the eastern suburbs of Urata City, [-] kilometers away from the city center. The prison is built in a field. The surrounding fields are all planted with rice seedlings. The green rice seedlings are blown by the breeze, turning over layers of green waves and emitting waves. The sound of rustling makes people feel relaxed and happy.

After Wu Jiang and Xiao Ke's car got off the Changpu Expressway, they turned left and headed towards the No. 20 Prison. All prisoners here were serious prisoners, with sentences of at least 24 years or more, as well as those with suspended sentences and death row prisoners. Therefore, The prison is very tightly guarded, with guards on duty [-] hours a day and snipers to prevent murderers from escaping.

There are surveillance videos everywhere here, there are no blind spots.Infrared thermal imaging cameras are installed at the entrances and exits. Its main purpose is to monitor the temperature distribution in the environment, because human body temperature is normally higher than the ambient temperature. If there is a living person hidden in the carriage, the display screen of the thermal imaging camera will A human-shaped heat source feedback will appear, and it will be more difficult for the prisoner to escape than to reach the sky.
