Looking up at the sky in the drizzle sounded very artistic.
But in reality, if one saw such a person on the street, and it was close to ten o 'clock at night, most people would think that the person was either mentally ill or mentally traumatized.
Clearly, in the old city area in front of the station tonight, the scattered pedestrians in the rain, whether they were walking or riding, looked relatively normal. Not to mention standing in the dark to look up at the sky, there was not even one strolling in the rain.
In fact, even if someone looked up, it would be difficult to see the three drones flying at an altitude of nearly forty meters with black paint.
"Suspected target found on Drone No. 2. Further confirmation is in progress." Li Ying's voice sounded in the command vehicle.
The five people in the command vehicle and the police officers in the city bureau's command center. At the same time, they shifted their gaze to the screen of Drone No. 2 on their respective surveillance walls.
Under the night vision lens, a person wearing a dark raincoat and riding a dark bicycle was slowly riding in the rain.
Li Ying's left hand controlled the drone to accelerate and fly in front of the rider. At the same time, her right hand adjusted the high-speed camera. After locking onto the target, the lens automatically adjusted the focus.
When the rider was about to pass by a dim yellow street lamp, the high-speed camera feed back showed that the rider was wearing a red raincoat and there were a few strands of rain-soaked long bangs hanging down from her forehead.
"Eliminated. The target is female. Drone No. 2 continues to search." When the people in the command vehicle and the command center saw the rider's characteristics, Li Ying's voice sounded again. At the same time, the image of Drone No. 2 also shifted from the rider to the small courtyards on both sides of the alley.
Although the suspect was not found, the city bureau leaders in the command center and the members of the evaluation team watching from the side were fully aware of the high efficiency of the three drones.
Especially the leaders in charge of criminal investigation, each of them began to feel itchy and wondered when they would be able to truly distribute this thing. With this thing to track, lock onto, and investigate from the air, it would save a lot of trouble for the basic investigators.
Especially the reaction speed of the reconnaissance drone, it was indeed a good thing that could greatly improve the efficiency of field cases.
"Drone No. 1 reporting, suspected target found in Courtyard No. 46 in the eastern section of North First Alley." About three minutes later, Qu Sen's voice sounded from the speakers in the command vehicle and the command center at the same time.
On the surveillance screen of Phone 1, a man in a raincoat was walking through the courtyard toward the door of the main building.
The courtyard was very small. By the time Qu Sen adjusted the drone's position, the man had already crossed the courtyard and stood in front of the door. Then, he took off his raincoat and held it in his right hand. His left hand reached into his trouser pocket as if he was looking for his keys.
Qu Sen moved the drone to hover above the courtyard gate, and at the same time, the high-speed camera locked onto the man's back.
Not long after, the man took out the key from his pocket, opened the door and entered the house. The moment he turned around and closed the door, the high-speed camera captured his profile with his head slightly lowered. After the door closed, about two seconds later, the lights in the room came on.
Qu Sen controlled the drone to maneuver around the house, looking for a view of the interior. The command vehicle had already begun to compare the side profile captured earlier with Huang Ansheng's photo.
Due to the lack of facial features in the photo, the photo comparison system was unable to identify the person. However, based on visual inspection, the two were at least 50% similar.
"Car 1 requests to approach the target building and use the technical reconnaissance drone for further confirmation." Qu Sen controlled the drone to fly around the house twice. After failing to find a suitable angle, he picked up the console and asked for instructions.
"Agreed, you can drive the car to the junction of Wenying Road and Beiyi Hutong and find a suitable place to fly." The figure of the on-site commander came out of the command vehicle.
"Roger, Car 1 is in position." While Qu Sen responded with the console, the off-road vehicle driver had already started the car and drove to the junction of Wenying Road and Beiyi Hutong.
Because it was still impossible to confirm whether the target Qu Sen found was Huang Ansheng, Drones 2 and 3 were still searching the area marked out by the command vehicle.
After Qu Sen's Car 1 found a suitable place to park at the intersection, Drone 1 quickly returned. Because there was a lot of water on the ground, it landed directly on the roof of the car.
While Liu Zhiquan got out of the car and retrieved Drone 1, he placed the technical reconnaissance drone on the roof of the car. Then the drone quickly took off and flew directly in the direction of the suspected target's house.
The technical reconnaissance drone, which was less than 11 centimeters in diameter, quickly found a suitable observation position. However, although the suspect in the house was walking back and forth on the phone, it was still impossible to capture his face.
And because of the glass and the interference of the rain, it was completely impossible to collect the sound of the phone call in the house. A few seconds later, the person in the house hung up the phone and turned directly into the house on the east side.
Qu Sen controlled the drone to approach the east window and found that the curtains were tightly blocked. He could only see the shadow of the person projected on the curtains. After wandering around the house for a while, the person seemed to be lying down, and then he could no longer capture any useful information.
Qu Sen simply controlled the drone to cruise in front of the house and soon found that the window in the west room that could be opened was open. Although it was only half-open, the technical reconnaissance drone could fly in.
After adjusting to the right height in the air, the technical reconnaissance drone flew directly into the house through the window in an upward position.
"Brother, don't worry, now the police are investigating the cameras on the street. They don't have time to watch us."
…
"I did, I rode around the house before entering the yard. I leaned against the door and looked for a while. It's raining, there are no ghosts outside. "
…
"I just called Little Dongbei and told him to drive over after one o 'clock. Hmm … Hmm … Don't worry, first deal with the phone, MP3 player, and so on. Those things can't be stored for another half a month, and the market will drop a lot. "
…
"Okay, let Little Dongbei send me to Facai, pick me up after two o 'clock … Okay, I'm hanging up."
There was no interference in the house at all. The sound signal collected by the technical reconnaissance drone was very clear, but the other party spoke in a dialect, so Qu Sen didn't understand much. However, Deputy Director Xiao could understand. While listening to the voice from the laptop speaker, he quietly translated it into Mandarin for Qu Sen to hear.
"Who is Little Dongbei?" Qu Sen asked in a low voice when there was no more sound in the house.
"His name is Zhang Wenren. He grew up in Changchun's grandmother's house when he was a child and came back when he was in middle school. He has a minivan and now works all day near Lantern City. "Deputy Director Xiao gave Little Dongbei's personal information.
"Do you think the person in the east room is Huang Ansheng?" Qu Sen asked again.
"Ninety percent!" Although Deputy Director Xiao said ninety percent, from his expression, he had already determined that the person in the east room was Huang Ansheng.
Compared to Deputy Director Xiao's optimism, the people in the command center were more cautious. They judged that the suspect Qu Sen caught was most likely Huang Ansheng.
However, even if the person in the house was not Huang Ansheng, from the content of his previous phone call, he was certainly not a good person. At the very least, he was a smuggler.
Since the informant had discovered Huang Ansheng, the optimal tracking time had passed. Even if Qu Sen's suspect was not Huang Ansheng, he should have already entered a building.
The on-site command center issued an order. The second drone immediately flew to the top of the suspect's house to monitor the environment outside the room. The third drone returned to replace the battery and took over when the second drone's battery was low.
On Qu Sen's side, because the door of the east room was covered with a curtain, there was only a certain gap below. However, the gap was only about three centimeters high, and there was a high density of spikes below the curtain. The risk of the drone sneaking into the house was too high.
After a round of observation, Qu Sen simply parked the drone on the roof beam of the central room. He turned off the rotor and lens to save power, leaving only the sound pickup component working.
About ten minutes later, there was a faint sound of snoring coming from inside the house. Everyone in the first car, including Qu Sen, pricked up their ears and carefully listened to the suspect's intermittent snoring. They did not dare to be careless.
Above the roof outside the house, at a height of about fifteen meters, UAV No. 2 hovered quietly in the drizzle. The high-speed lens under the body of the drone slowly rotated, constantly capturing the movements around the house.
On the other side, the command center was arranging to investigate the peripheral information.
Previously, through the monitoring, they had obtained two names: "Little Dongbei" and "Get Rich." Little Dongbei's basic situation was consistent with what Deputy Director Xiao had said. The other person called "Get Rich" had not collected any relevant information for the time being.
The owner of the house where the suspect lived was called Yu Shengshui. He was a seafood wholesaler, and his registered residence was in the old city area. A year ago, he bought a building near the seafood market in the south of the city, and the house in the old city area had been vacant.
When the patrol officers investigated the comprehensive situation of the area, the information they collected was that Yu Shengshui had been listing the old house with a housing agent. However, the rent was relatively high, and there had been no renters for more than half a year.
When it was close to one o 'clock in the morning, more than thirty field officers from the two branches and thirteen vehicles were all on standby. The third drone took over the reconnaissance mission of the second drone. After the second drone was recovered and confirmed that it was functional, it replaced the battery and set off again.
More than two minutes later, it hovered above Little Dongbei's house, three blocks away from the target location.
At one o 'clock in the morning, the lights in the little boss's house lit up. Five minutes later, a young man walked out of the house. Through the special appearance captured by the drone's lens, the patrol officers determined that the man was Little Dongbei.
After Little Dongbei was discharged from the hospital, he directly got into his minivan. Then, the car started and drove in the direction of the suspect's house.
About ten minutes later, Little Dongbei drove past Qu Sen's off-road vehicle and drove into Beiyi Hutong. Soon, he stopped outside the courtyard of the target house.
Suddenly, a phone rang from the laptop's speaker. The moment Qu Sen heard the sound, he immediately restored the drone's power and turned on the camera. This was because he was worried that if he started it too late, the dust stirred up by the rotor would fall and alert the suspect.
