Zhang Dinghui opened his eyes all of a sudden, and then he felt his heart beating wildly and his temples bulging, as if he was about to break through his innateness.
As the director of the Meiyang City Bureau, although Zhang Dinghui receives countless calls every day, there are very few calls in the early morning, especially after 3 o'clock in the morning, when normal people are already asleep, so it is not a particularly urgent call.
Even when Jiang Yuan came to investigate the bombing case, the news came at 3 o'clock in the morning...
Zhang Dinghui's eyes were round, as if a martial arts master was thinking before his death: Jiang Yuan is really in Meiyang City.
Zhang Dinghui skillfully grabbed a pill box from the bedside table, opened it and poured it into his mouth. Then he pressed his temples with his hands, took a few breaths to suppress the nausea in his chest and abdomen, picked up the phone and said:
"I am Zhang Dinghui."
Wang Sheng also knew that it was late at night, so he explained as quickly as possible: "Director Jiang Yuan confirmed that the suspect Ren Kuangshan abandoned his car in Zhuyuan County on the day after the incident and entered on foot along the railway track.
Zhuyuan County Railway Station, take Express 2*** to leave the country.”
"Leaving Meiyang City?" Zhang Dinghui breathed an inexplicable sigh of relief.
"We have left, but the investigation in Zhuyuan County still requires our cooperation. Jiang Yuan has already set off for Zhuyuan County. In addition, the leaders of the ministries and commissions have also set off from Changyang City by helicopter.
We expect to arrive at Zhuyuan County Railway Station in about two hours." The last sentence Wang Sheng said was the main reason for the call.
Zhang Dinghui composed himself and repeated: "In a helicopter? Are you trying so hard?"
"It's been five days since the crime happened, and the leaders are probably very anxious." As the captain of the criminal police detachment, Wang Sheng understands the mood of a sudden breakthrough when such a big case is difficult to solve. He is even more excited than his wife giving birth to a child, and even more excited than a cannon.
A friend's pregnancy is similar to the fact that the child of a sex friend is not one's own.
Zhang Dinghui looked at his watch and understood what Wang Sheng meant. He sighed and said, "Okay, let's go to Zhuyuan County too."
"Yes." Wang Sheng paused and then said: "I have sent a police car to pick you up. It will take about 10 minutes to arrive downstairs."
"Okay. Thank you for your hard work." Zhang Dinghui had nothing to say, so he got out of bed, washed and started to get dressed.
"Is there a case?" In the next room, my wife was also woken up. The two of them had slept in separate rooms a long time ago, otherwise, Zhang Dinghui's phone ringing would have caused two patients with myocardial infarction.
"Well, you can continue to sleep." Zhang Dinghui didn't say much about the case, dressed carefully and went out.
Outside the door, the secretary was already waiting.
The car drove very steadily, and there was a police car clearing the way. It was about 3 o'clock in the morning, and there was no need for traffic control.
After sleeping in Zhuyuan County, when Zhang Dinghui opened his eyes again, it was already dark outside.
"The leader's helicopter will land in 10 minutes. Please have a drink of water and we should go there." The secretary thoughtfully handed over the thermos cup.
Zhang Dinghui drank most of it in one go, without worrying that the water in the thermos cup would burn his mouth.
Power is like a cage. When it covers the thermos cup, it will narrow the range of changes in the water temperature in the thermos cup. The greater the power, the narrower the range of changes in water temperature.
"Let's go." Zhang Dinghui put on his shoes, straightened his collar a little, and stepped out of the car door.
Outside the door, subordinate comrades were already waiting.
"Thank you for your hard work. You all woke up at night. How is your heart?" Zhang Dinghui nodded to everyone and chatted while walking.
"The matter of 12 quick-acting Jiuxin pills."
"16."
"I used nitroglycerin."
Everyone talked half-jokingly, and arrived at the place without walking too far. Without anyone's guidance, they automatically and consciously stood where they should stand.
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 people on the ground.
The helicopter comes down.
Song Tiancheng opened his eyes, looked out the window, drank some water, put on his shoes, and got out of the helicopter.
Outside the door, local comrades were waiting.
…
Zhuyuan County Railway Station Police Station.
The railway station police station vacated the conference room and director's office, but did not even let go of such a large group of people.
When leaders come out with their people, they have to work. Leaders can hold teacups and talk with a smile, while subordinates have to find a place to write speech materials, etc.
Huang Qiangmin led people to welcome him out, greeted the leader, and then said: "Jiang Yuan is watching the scene on the platform, I will give him a call..."
"Don't worry, let's wait until he finishes reading and respond. We are here to understand the situation, not to cause trouble." Song Tiancheng said, looking around, and then said: "The most powerful clue now is Jiang
It’s provided by Yuan Yuan, so those who eat should not be dissatisfied that the cook is slow.”
Turning around, Song Tiancheng greeted Zhang Dinghui again: "Director Zhang, I want to 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 out his subordinates, and said this specifically to avoid Zhang Dinghui's misunderstanding.
This time, Zhang Dinghui has been more active than usual, also to give face to Song Tiancheng and Jiang Yuan.
The last time the gambling house explosion in Meiyang City happened, it was Song Tiancheng who brought Jiang Yuan there. This is 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 said with a smile on his face: "We are helpers."
"Hahaha." Song Tiancheng pretended to be amused, and his expression was no longer so serious. He said a few more words and turned to ask Huang Qiangmin: "Jiang Yuan came over specifically to look at the platform. Why? Is the surveillance video unclear?"
If monitoring is unclear, the reliability of clues will be compromised.
Huang Qiangmin shook his head: "The surveillance is appropriate. However, the suspect Ren Kuangshan's car was a slow train. It stopped for a long time, 12 minutes. During this period, there were also trains stopping in the next lane. Jiang Yuan was worried that the suspect would sneak across the platform.
Got into another car."
Song Tiancheng's eyelids twitched. For him, the person in charge of the case, this answer was a horror story. He couldn't help but say: "Didn't you say that the suspect's target is the Northeast? He also walked all the way to the Northeast."
"The normal reasoning is this. Jiang Yuan is mainly just in case." Huang Qiangmin knew what Song Tiancheng was worried about, and he also felt that Jiang Yuan's speculations were just horror stories.
The train next to me was heading east. If the suspect really boarded it secretly, and a group of people from his own party mobilized and ran northeast, the story would make people shudder to think about it.
Huang Qiangmin felt that if he were the leader of the task force, if he encountered such a thing once, he would be shadowed for a lifetime. Because Ren Kuangshan will eventually be caught, even if he runs away now, the future of a prisoner of this level will be certain.
It will be red at the meeting.
Therefore, unless he died quietly in a foreign country, if Ren Kuangshan comes to the case in the future and tells such a completely different story, even if time has changed, the investigators of the case will never feel relieved.
.
Song Tiancheng also suddenly became serious: "Jiang Yuan has rigorous ideas. This guy was born to be a policeman."
"Now it's called the Holy Body of a natural detective." Zhang Dinghui said a newly learned word.
Song Tiancheng laughed again.
Not long after, Jiang Yuan returned with a group of technicians.
"How?" Song Tiancheng was not afraid to show his urgency. He came over by helicopter. He was really anxious.
"Judging from the situation at the scene, he did get into this car. He got into compartment 6." Jiang Yuan was talking about the information seen in the video, which was not unexpected.
Song Tiancheng breathed a sigh of relief: "It's OK, it's confirmed. In this case, it seems that the suspect has indeed gone to the northeast."
"Judging from the time, we should have gotten off the bus." Liu Jinghui looked at his watch: "We are two days late."
Song Tiancheng's expression changed slightly: "Ge Zhibing has gone to the border to set up defenses. I don't know if it can be blocked."
He looked at Jiang Yuan: "Catch and block, pursue this area, Jiang Yuan, what do you need?"
"The stop time and place of the train are clear, and the surveillance in each train station is complete. Now we are collecting surveillance at each station to see where the murderer got off. I have sent the request for co-investigation to the commander.
It’s done, this part, I’ll watch the video and it won’t take long, it just depends on how long it takes to deliver it to each place.”
The general express basically stops at stations, and it is normal to stop at twenty stations along the way. Even so, even if the stop time is 10 minutes at each station, the total stop time is only 200 minutes. If the time is doubled, it will be 400 minutes.
Minutes of parking time. During this period of time, the total video time of a train's entrance, exit and platform monitoring, whether there are ten, eight or more, is always count.
When the target person is already clear, Jiang Yuan does not need to watch these videos alone. He can organize a team of picture scouts to watch them together. For qualified picture scouts, watching such videos is a daily routine.
In addition, domestic AI systems have been used for gait analysis as early as 10 years ago. In addition, face recognition can also be used.
The systems at train stations or airports are very strict and will only remind you when the similarity is relatively high. Now that there is a definite time and place, you can completely lower the similarity requirement.
As for why it cannot be used at gas stations, it is because the monitoring settings and clarity of gas stations are poor, while train stations have professional portrait mounts.
For example, portrait mount monitoring is not about comparing faces by just taking pictures. First, it needs high definition, second, it needs fill light, and third, the shooting position must also be facing the front.
It is possible to rotate slightly left and right and up and down, but it is not possible to shoot from top to bottom or from left to right.
Therefore, the positions of portrait bayonet and vehicle bayonet are often very particular, and require a lot of coordination, which are not available in gas station monitoring.
Finally, a large number of surveillance photos means a large amount of storage or transmission. Assuming that the flow of people is 10,000, it is not surprising that the number of photos taken by the bayonet exceeds 100,000. Where there is demand, there will be no problem in accommodating these photos.
But there is no need to do this in locations that are not strictly necessary.
Listening to Jiang Yuan's brisk answer, Song Tiancheng's mood suddenly lightened up: "Okay, great, whoever it is, hurry up and call and let each place report the time they need, and show me the ranking.
Contact them personally.”
"Yes." The one did it immediately.
Liu Jinghui said quietly from the side: "When slow trains enter the station, we must also prevent suspects from jumping off the train in advance."
Song Tiancheng frowned again when he heard this.
Liu Jinghui added: "Generally, if you can't jump, the conductors are guarding the door. But if something happens, the conductors may not report it, so you must ask everyone clearly."
"That's good!" Song Tiancheng breathed a sigh of relief, as long as there is a solution. There are not many conductors on the train.
"It's best to find some passengers, such as those who bought tickets for the 6-car train, and ask them if they have any impressions of Ren Kuangshan. You can sit on the train for several hours or more than ten hours.
Everyone is familiar with them." Liu Jinghui paused and then said: "Ordinary people
It is possible that you just sleep or are insensitive to the people around you. You can pay special attention to the occupation of the passengers. Veterans, those who have worked in the military and police system, including some self-employed people, small traders, and those who have been in prison will be more sensitive to the people around them.
Attention is not limited to carriage 6..."
Liu Jinghui was talking about the skills of traditional criminal police officers. It is not a rare trick, but if it is really used, it will obviously require a lot of manpower and material resources.
Song Tiancheng carried out the arrangement without any setbacks. This kind of investigation is a burden to the ordinary criminal police team, but to the task force, it is like parents teaching their children, but it is nothing.
