Chapter 1163

3:30 AM.

The phone rang.

Zhang Dinghui opened his eyes all of a sudden, and then felt his heart pounding wildly, and his temples were bulging, as if he were about to break through to the innate stage.

As the director of the Meiyang Municipal Bureau, although Zhang Dinghui had to answer countless calls every day, calls in the early morning were extremely rare, especially at 3 AM, a time when normal people were already fast asleep. Calls that were not particularly urgent would not come in. It was only during the period when Jiang Yuan came to solve the explosion case that news would come at 3 AM for no reason...

Zhang Dinghui's eyes were wide open, as if a martial arts master before death was thinking: Jiang Yuan, really is in Meiyang City.

Zhang Dinghui skillfully grabbed a medicine box from the bedside table, twisted it open, and poured it into his mouth. Then, he pressed his temples with his hands, took two more breaths, suppressed the nausea in his chest and abdomen, picked up the phone, and said, "I am Zhang Dinghui."

Wang Sheng also knew it was late at night, so he explained as quickly as possible: "Director. Jiang Yuan confirmed here that the criminal suspect Ren Kuangshan abandoned the car in Zhuyuan County the day after the case occurred, walked along the tracks into Zhuyuan County Train Station, and took the 2*** rapid train to leave the border."

"Left the scope of Meiyang City?" Zhang Dinghui felt relieved for no reason.

"Yes, he left, but the investigation in Zhuyuan County still needs our cooperation. Jiang Yuan has already set off for Zhuyuan County. In addition, the leaders of the ministries have also set off from Changyang City, taking a helicopter, and are expected to arrive at Zhuyuan County Train Station in about two hours." The last sentence Wang Sheng said was the main reason for the call.

Zhang Dinghui steadied himself and repeated: "Taking a helicopter? Is it that desperate?"

"It's been five days since the case occurred, the leaders are probably anxious too." As a criminal police detachment leader, Wang Sheng understood the feeling of a sudden breakthrough when such a major case was difficult to solve; it was even more exciting than a wife giving birth to a child, even stronger than a fuck buddy getting pregnant, similar to a fuck buddy's child not being one's own.

Zhang Dinghui looked at his watch, understood Wang Sheng's meaning, sighed, and said, "Fine, let's go to Zhuyuan County too."

"Yes." Wang Sheng paused and added, "I sent a police car to pick you up, it will take about 10 minutes to get downstairs."

"Good. Thank you for your hard work." Zhang Dinghui had nothing else to say, turned over and got out of bed, washed up, and started putting on clothes.

"Is there a case?" In the next room, his wife was also woken up. The two had been sleeping in separate rooms long ago, otherwise, Zhang Dinghui's phone ringtone would have created two heart attack patients.

"Yes. You continue to sleep." Zhang Dinghui didn't say much about the case, dressed carefully, and went out the door.

Outside the door, the secretary was already waiting.

The car drove extremely steadily, with a police car leading the way, and it was past 3 AM, so there was no need for traffic control.

Sleeping all the way to Zhuyuan County, when Zhang Dinghui opened his eyes again, it was already dawn outside.

"The leader's helicopter will land in 10 minutes. You drink some water, and we should go over." The secretary thoughtfully handed over a thermos cup.

Zhang Dinghui drank more than half in one breath, not worried at all that the water in the thermos cup would burn his mouth.

Power is a cage. When it covers a thermos cup, it narrows the range of temperature change of the water inside the thermos cup. The greater the power, the narrower the range of temperature change.

"Let's go." Zhang Dinghui put on his shoes, tidied his collar slightly, and stepped out of the car door.

Outside the door, subordinate comrades were already waiting.

"Everyone worked hard, you were all woken up at night. How is your heart?" Zhang Dinghui nodded to everyone, chatting while walking.

"It's a matter of 12 quick-acting heart pills."

"16 pills."

"I used nitroglycerin."

Everyone was talking half-jokingly, and they didn't walk far before they arrived at the place. Without anyone guiding them, they automatically and consciously stood in the positions they should stand in.

Woo woo woo...

The noise of the propeller was annoying, the wind blew up the dust on the ground, and also blew up the smiles of the people on the ground.

The helicopter landed.

Song Tiancheng opened his eyes, glanced out the window, drank some water, put on his shoes, and drilled out of the helicopter.

Outside the door, local comrades were already waiting.

Zhuyuan County Train Station Police Station.

The train station police station vacated both the conference room and the director's office, but still couldn't hold such a large group of people.

Leaders bringing people out all need to work. Leaders can hold teacups and talk with smiles, but subordinates all have to find places to write speech materials, etc.

Huang Qiangmin brought people out to greet the leaders and said, "Jiang Yuan is watching the scene on the platform, I'll call him..."

"No rush, wait until he finishes watching and comes back. Our group of people are all here to understand the situation, not to make trouble." Song Tiancheng looked left and right and added, "The most powerful clue now is provided by Jiang Yuan. Don't complain about the cook being slow when eating."

Turning his head, Song Tiancheng greeted Zhang Dinghui again: "Director Zhang, thank you for your help this time..."

This case is not the responsibility of the Meiyang Municipal Bureau, and the latter only needs to cooperate with the work. Song Tiancheng pointed to his own subordinates and said it specifically to avoid Zhang Dinghui misunderstanding.

This time, Zhang Dinghui was already more active than usual, which was also giving face to Song Tiancheng and Jiang Yuan.

Last time, the gambling den explosion case in Meiyang City was when Song Tiancheng brought Jiang Yuan to descend, which was also a favor that should be returned.

At the same time, Zhang Dinghui and Song Tiancheng had known each other for a long time. Zhang Dinghui was full of smiles and said, "We belong to being kitchen helpers."

"Hahaha." Song Tiancheng pretended to be amused, his expression was not so serious, said two more sentences, turned his head and asked Huang Qiangmin: "Jiang Yuan ran over to watch the platform specifically, why? Is the surveillance video unclear?"

If the surveillance is unclear, the reliability of the clue will also be discounted.

Huang Qiangmin shook his head: "The surveillance is suitable. However, the car that the suspect Ren Kuangshan got on is a slow train, and the stop time is very long, 12 minutes. During this period, there were also trains stopping in the adjacent lane. Jiang Yuan is worried that the suspect secretly crossed the platform and got on another train."

Song Tiancheng's eyelids jumped. For him, who is responsible for the case, this answer can be called a horror story, so he couldn't help but say: "Isn't it said that the suspect's target is the northeast? He is also going all the way to the northeast."

"Normal reasoning is like this, Jiang Yuan is mainly to prevent accidents." Huang Qiangmin knew what Song Tiancheng was worried about, and he also felt that Jiang Yuan's guess was a horror story.

The train next to it is heading east. If the suspect really secretly got on it, and the group of people on his side mobilized the masses to run to the northeast, the story would make people shudder just thinking about it.

Huang Qiangmin felt that if he were the person in charge of the special task force, encountering this kind of thing once would leave a shadow for a lifetime. Because Ren Kuangshan will eventually be caught, even if he runs away now, this level of criminal will definitely be on the red notice in the future.

Therefore, unless he dies silently in a foreign land, otherwise, after Ren Kuangshan is brought to justice in the future, if he confesses such a story of going in the opposite direction, even if time has passed, the investigators of that year will never be relieved in their hearts.

Song Tiancheng also became serious all of a sudden: "Jiang Yuan's thinking is rigorous. This guy is a person born to be a police officer."

"Now it's called a born criminal police holy body." Zhang Dinghui said a newly learned term.

Song Tiancheng laughed loudly again.

Not long after, Jiang Yuan returned with a group of technicians.

"How is it?" Song Tiancheng was not afraid to show his urgency. He had already taken a helicopter over, he was really anxious.

"From the situation at the scene, he did get on this train. He got on carriage 6." Jiang Yuan said the information seen in the video, which was not unexpected.

Song Tiancheng breathed a sigh of relief: "It's good to be confirmed, it's good to be confirmed. In this way, it seems that the suspect did go to the northeast."

"From the time point of view, he should have already gotten off the train." Liu Jinghui looked at his watch: "We are two days late."

Song Tiancheng's expression moved slightly: "Ge Zhibing has already gone to the border to deploy defenses, I don't know if he can block him."

His eyes looked at Jiang Yuan: "Surround and intercept, in terms of pursuit, Jiang Yuan, what do you need?"

"The train's stop time and location are clear, and the surveillance inside each train station is also complete. Now it is to collect surveillance from various stations to see where the murderer got off the train. I have already sent the request for assistance to the command center. For this part, I don't need much time to watch the video, it just depends on how long it takes for various places to send it over."

Jiang Yuan answered quickly, obviously having thought it through.

Rapid trains basically stop at every station, and it is very normal to stop at twenty stations along the way. Even so, even if each station has a stop time of 10 minutes, it stops for a total of 200 minutes. In the case of doubling the time, it is 400 minutes of stop time. During this time, the surveillance at the entrance and exit of a train and the platform, whether it is ten, eight, or more, the total time of the video is always countable.

In the case where the target person is very clear, Jiang Yuan doesn't need to watch these videos alone, he can completely organize an image investigation team to watch together. For qualified image investigation, watching this kind of video is daily life.

In addition, domestic AI systems have been applied to gait analysis as early as 10 years ago. Besides this, face recognition can also be pulled out for use.

The systems of train stations or airports are set relatively strictly, belonging to situations where the similarity is relatively high before reminding. Now that there is a determined time and location, the requirement for similarity can be completely adjusted lower.

As for why it couldn't be used at the gas station, it is because the setting and clarity of the gas station's surveillance are different, while the train station has professional portrait checkpoints.

For example, the surveillance of portrait checkpoints is not just stupidly filming to compare faces. First, it needs high definition, second, it needs fill light, third, the shooting position must also face the front face, and there can be slight left and right rotation and up and down rotation, but shooting from top to bottom, or from left to right is not okay.

Therefore, the positions where portrait checkpoints and vehicle checkpoints are arranged are often very particular, and there are many things that need to be coordinated. These are all things that gas station surveillance does not have.

Finally, the large amount of shooting by surveillance means a large amount of storage or transmission volume. Assuming the flow of people is 10,000, it is not strange that the photos taken by the checkpoint exceed 100,000. In places with demand, accommodating these photos is no problem, but in places without rigid demand, there is no need to do so.

Song Tiancheng listened to Jiang Yuan's brisk answer, and his mood suddenly became brisk: "Good, very good, that someone, hurry up and call to contact, let each place report the time they need themselves, rank them and bring them to me to see, I will contact them personally."

"Yes." That someone immediately went to do it.

Liu Jinghui said gloomily from the side at this time: "Slow train entering the station, also have to guard against the suspect jumping off the train in advance."

Song Tiancheng's brows wrinkled again when he heard this.

Liu Jinghui added: "Generally can't jump, the train attendant is guarding at the door. But in case there is a situation, the train attendant may hide it without reporting, must ask one by one clearly."

"This is good!" Song Tiancheng breathed a sigh of relief, as long as there is a solution. There are not many train attendants on a train.

"It is best to find some passengers, such as people who bought seats in carriage 6, you can ask if they have an impression of Ren Kuangshan. Sitting on the train for several hours, more than ten hours, the people around are all familiar." Liu Jinghui paused and added: "Ordinary people may just sleep, or are not sensitive to the people around them, you can pay special attention to the occupation of passengers, retired soldiers, people who have worked in the military and police system, including some individual households, small vendors, people who have been in prison, these people will pay more attention to the people around them, and it is not limited to carriage 6..."

Liu Jinghui is talking about the skills of traditional criminal police, which is not a rare trick, but when really used, it obviously also requires a lot of manpower and material resources.

Song Tiancheng arranged it without a stumble. This kind of investigation is a burden for ordinary criminal police teams, but for the special task force, it belongs to parents teaching children, nothing more.
