The group of people drove to a commercial area, and the speed of the car in front slowed down.
The voice of Captain Tang, the technical detective who had just introduced it, soon came from the intercom, saying: "We will use the technical investigation vehicle to lock the location of the mobile phone. Well, for older technical investigation vehicles, this time is usually
Turn off the walkie-talkie. Let’s do a test today. To increase the difficulty a little bit, we won’t turn off the walkie-talkie.”
"Received." Huang Qiangmin responded with a smile.
On the intercom, Captain Tang continued: "When we usually find a mobile phone, we first find the base station and then locate it at three o'clock. But this situation is only useful when making a call. The other method of searching through the base station has a relatively low resolution.
, it’s okay in the wild, but the more prosperous the city, the harder it is to use. This is not the case with technical detection locking... Well, I found it.”
The car in front drove away as he spoke, and then stopped at the downstairs of a residential building with a basement.
The community here is not closed, but a mixed-use apartment model. The four floors downstairs are all shops, and it is bustling like a small commercial community. The floors above the fourth floor are all residences or apartments, with some
There are more than 20 buildings, and it is difficult to individually lock the phone in which building it is, even when the other party is not calling.
The technical investigation vehicle was different. It drove smoothly to the building of No. 6 without any hesitation.
The basic type of technical investigation vehicle is the radio direction finding vehicle that often appears in spy war dramas. It can monitor the surrounding radio waves while driving, so as to determine the location of the wireless signal as much as possible.
In the early years, when electromagnetic signals were not so wild, a radio direction-finding vehicle drove up and arrived near a building, basically determining its location.
In today's environment, the electromagnetic environment has become more complex, and the height and density of buildings have also increased. It is almost impossible to lock a building on the street and just a person as it was a few decades ago.
It was the environment that made it difficult.
So, after the technical investigation vehicle stopped, it took out a few more small boxes.
"This is an individual soldier. Its full name is an individual soldier's portable code detection equipment. Each one costs 100,000 yuan. Let's use this to solve the last mile problem." Captain Tang opened several small boxes, turned on the device and walked upstairs.
The individual soldier actually simulates the base station, calls the surrounding mobile phones, and then lets the mobile phones register, register and report on their own. The collected information can be integrated for research, or they can focus on finding a certain mobile phone.
Several technical scouts first took the elevator to the 10th and 15th floors, then explored up and down, and finally concentrated on the 11th floor.
This apartment has a four-staircase layout with sixteen rooms. The rooms are relatively small, with one door next to the other.
Captain Tang showed Huang Qiangmin and Jiang Yuan the signals on the individual soldiers, and said: "Individual soldiers can be used by the criminal police after they have been trained. As for the method, they usually only look at the signal strength. Each of our families
Find it."
"The signal of this house is 8, the signal next door is 9, and the signal next door is 8 again. Then let's go back and take another look. The signal is indeed 9, so it's in this house." Captain Tang walked around with the single soldier.
, determined the place and gave up the position.
The few detectives who followed naturally gathered at the door.
Boom, boom, boom.
Boom, boom, boom.
The detectives knocked on the door, but no one answered.
Captain Tang whispered: "The phone is inside, and the person must be inside."
This evidence is enough. Wu Junhao nodded and said: "Get ready to break down the door."
After saying that, Wu Junhao shouted: "Police, if you don't open the door again, we will break down the door by force."
Ga...
The door was opened a crack.
Wu Junhao rushed in immediately, not looking like he had just been shot three times through a body armor.
Liu Wenkai and other criminal policemen also rushed in. The criminal policemen from the Zhengguang Bureau even had Type 92 - in Shannan Province, the cannons issued were often small cannons, and the Type 92 was a high-end product, but in the capital, revolvers like
Such a shameful thing has long since been eliminated.
"Who...are you looking for?" The door opened, revealing a panicked girl with nightclub smoky makeup and black stockings, looking timid.
"Ah...where is Li Xiangming?" Liu Wenkai was holding the gun, frowning, but fortunately he didn't use too much force...
The girl shook her head.
"May I have your name?"
"Li Shunyang."
"Who are you, Li Xiangming?"
"my brother."
"Where did he go?"
The girl shook her head again.
"You stand on the edge." Liu Wenkai raised his right hand, put it down again, and then waved his hand to signal the girl to stand against the wall.
The apartment is not big, it is basically a larger one bedroom and one living room. Except for the kitchen and bathroom, there is no place to hide people.
Several police officers from the technical investigation also frowned and whispered beside Jiang Yuan and Huang Qiangmin: "Maybe you left your mobile phone behind? Do you have a mobile phone specially used for work?"
At this time, the policemen in front of Jiang Yuan all came up. Jiang Yuan looked sideways at the girl standing against the wall and said slightly: "Please control this Li Shunyang."
Wu Junhao inside hesitated for a moment, because it was not convenient for him to do anything, so he just stood aside and said to Li Shunyang: "Raise your hands flat, are you carrying any weapons?"
"You don't have to be so polite." Jiang Yuan shouted again and said: "You have to guard the team, Captain Tang, you handcuff him."
"Do you think I'm good at handcuffing women?" Liu Wenkai's character has never been very serious, but he still took the handcuffs as he was told, came to Li Shunyang, and said: "Please turn around..."
"Why... why?" Li Shunyang looked pitiful.
Liu Wenkai couldn't help but hesitate a little. If he wasn't in a hurry, he would actually tend to wait until the policewoman arrived before taking action, so as not to cause any trouble later.
Jiang Yuan took a step forward at this time, looked at Li Shunyang's feet, and said: "Because this is Li Xiangming himself. Judging from the foot shape and gait, they are undoubtedly male. They can also match the footprints in the file."
"male?"
At this time, not only Liu Wenkai and Wu Junhao, but also the technical investigators outside the door looked over.
The girl who was pretending to be pitiful also looked shocked and tried her best to say: "I'm not..."
"Turn around! Put your hands up!" Wu Junhao understood what Jiang Yuan said. He didn't care about the suspect's excuses, and his voice suddenly became louder.
The girl wanted to pretend again, but Liu Wenkai's voice next to her became fierce: "Li Xiangming! Don't cause trouble for yourself! You have enough trouble!"
There were so many police officers in the room, and they all heightened their vigilance. Li Xiangming had no luck anymore, and his voice returned to a normal male voice:
"I know. I just happened to change into a cosplay costume..."
Now, everyone was confirmed.
Liu Wenkai "clicked" twice and separated Li Xiangming's legs: "Put your hands on the wall. Let me search you now!"
Since the other party is a man, Liu Wenkai has nothing to worry about.
Liu Wenkai first lifted up Li Xiangming's short skirt to make sure there was nothing in the bulging bustle, and then pulled open the bra with the steel ring on the chest to look at it, then curled his lips and said with a smile: "It's really sexy.
."
Li Xiangming said calmly: "If you like it, I have several sets of small skirts."
"Your voice can easily cause drama." Liu Wenkai cuffed Li Xiangming's hands unmoved, and then began to inspect the objects in the room.
Several technical detectives also looked a little dazed. Captain Tang put away his single soldier and said happily: "The life of a criminal police officer is still interesting."
"You don't usually encounter this kind of thing." The criminal policeman who came with him was also watching the fun.
There were a bit too many people coming. People outside were chatting, while people inside were conducting surveys step by step.
Although it is a small case, the steps of survey are still indispensable, but the area and quantity of survey can be reduced.
Captain Tang watched for a while and didn't want to waste time anymore. He turned to Huang Qiangmin and said: "This is how our actual combat is going. As far as technical reconnaissance vehicles are concerned, the one we customized is pretty good..."
He was ready to say goodbye and leave.
At this time, Jiang Yuan stopped him and said: "Team Tang, everyone is here, let's check one more person."
"Uh...who?" Captain Tang hesitated for a moment. In theory, the call for technical investigation must be approved by the provincial department or the municipal bureau. However, this time even the technical investigation vehicle has been dispatched, so naturally it has already passed by.
process. Despite this, Captain Tang was still instinctively wary of using technical investigation methods.
Jiang Yuandao: "I took a few fingerprints on the stolen goods, scanned the police ID, and found a habitual criminal with a history of collecting stolen goods. I will ask Li Xiangming to identify his phone number. You can locate it. Let's go directly.
Grasp?"
"Then... okay." Captain Tang then took Jiang Yuan and others downstairs, got into the technical reconnaissance vehicle himself, came back through the operation, and said: "Judging from the position of the mobile phone, it should be nearby, a few hundred meters away."
."
"Then walk over." Jiang Yuan called to Wu Junhao, Liu Wenkai and Mu Zhiyang, plus a group of young and energetic policemen, and they arrived in a mighty manner...
A hotpot restaurant.
The suspect and two other people were eating hot pot and drinking iced Coke.
"Be careful with the bottom of the pot, it's very hot. Find someone to get a lid or something. If a suspect goes crazy and sets off a hot pot or something, let me control the pot first!" Wu Junhao is very experienced in arresting people. Just a few words
After the arrangements were made and the candidates were assigned, several main arresters were asked to change their clothes and then enter through the front and back doors together.
The preliminary preparation work seemed a bit cumbersome. Because of this, when it came to the arrest stage, the three suspects were captured without any knowledge and without any resistance.
"These two are also involved in a case and are on the run." Liu Wenkai checked the fingerprints of the three of them on the spot and then rounded up the two hot pot partners of the criminal who was selling stolen goods.
At the same time, several mobile phones and more than a dozen figurines were found in the backpacks of the three people.
"I'll scan my fingerprints." Jiang Yuan became interested and borrowed a private room in the hotpot restaurant and painted the figures on the spot.
