Mysterious case search [criminal investigation]

"Comrade police, I really don't have the authority to copy the surveillance records for you. It's really not that I don't cooperate." In the property center of Yuhe Mansion, a man in a white shirt looked like he was about to cry.

"If you don't have authority, then call someone who has authority to come over immediately. I showed you the police officer's ID card, and you called to check your identity. Now the police are handling the case, are you trying to obstruct law enforcement?" Qi Chuchen pulled out from the back of his waist The handcuffs were slapped directly on the desk, "If you want to interfere with official duties, I can just handcuff you away."

Gao Rui shivered beside him, feeling that Brother Qi, who had returned from sick leave, had changed!Various roles are seamlessly connected. Before that, he was a tabloid reporter, and now he is a domineering president. His temper was bad before, and now it is getting worse.

"Officer! In that case, can I call the leader right away? Quickly, give me 2 minutes." The voice of the white shirt on duty was trembling when he spoke.

"Hurry up, if you still can't cooperate after hanging up the phone, then I have to call our colleagues over and seal off the scene. At that time, more than a dozen police vehicles will be sealed up. Tomorrow, the headlines of the major media will be on the front page of your community. Big." Qi Chuchen randomly pulled an office chair nearby and sat down, crossing Erlang's legs and starting to shake his feet.

A few minutes later, the white shirt respectfully ran up to Qi Chuchen,

"Officer, I called our manager, and he will come right away. I can take you to the monitoring room now. You can watch whatever monitoring you want, and the manager will come over and copy it for you in person. Can you read it?"

Qi Chuchen waved his hand: "Let's go."

Pi Dian Dian in the white shirt led Qi Chuchen and his party into the monitoring room, and temporarily called out the security guard sitting inside.

Qi Chuchen pointed at Luo Zheyu, "I want to see all the surveillance records from Wednesday night to the present of the surveillance of the elevator at his door."

"C2802" Luo Zheyu said a room number beside him,

"Okay, okay." The staff typed a few times on the computer in the middle, and then turned to Qi Chuchen and said, "Okay, officer, if you want to fast forward and back, press these two arrows, pause, and continue playing with the space bar , very simple".Qi Chuchen waved his hand to signal that he could go out.

Gao Rui sat in front of the computer and began to fast-forward the monitoring: most of the time the corridors were empty, and occasionally when the elevator door opened, the cleaning lady came out to mop the floor, wipe the walls, and clean, or the maintenance staff came up to check the equipment.

Until after [-]:[-] on Friday morning, the elevator doors opened again, and a young girl came out: shoulder-length hair slightly curly, light makeup, curved willow eyebrows, skin that looked fair and delicate, double eyelids, eyelashes She is very upturned, her eyes are relatively large, and she wears bean paste-colored lipstick; she is wearing a high-necked linen-colored long-sleeved tight gauze dress with the hem tucked into a plaid skirt, a pair of flesh-colored stockings on her legs, and a pair of nude-colored high-heeled shoes on her feet. He was carrying a small dark red shoulder bag, and his nails were also painted bright red.

Qi Chuchen reached out and pressed the pause, then turned to look at Luo Zheyu: "Do you know this girl?"

Luo Zheyu shook his head, "I haven't seen it." Qi Chuchen tapped the space, and the monitoring continued to play.

The girl stepped out of the elevator, walked to the door of Luo Zheyu's house, knocked on the door a few times, and rang the doorbell after a while.Waiting for half a day and seeing that no one opened the door, he leaned forward and approached the door, put his ear on the door and listened, then turned around and opened the shoe cabinet, took out a pair of slippers to put on, took out the key from the bag to unlock it, and pressed his fingerprints .

The door clicked open.The three were shocked! ! !

"Chen Jia." Luo Zheyu's voice was full of disbelief.

"I'm caocaocao, this is Chen Jia???" Gao Rui called out directly.

"Go back and read it again." Qi Chuchen interrupted Gao Rui's exclamation.

When the replay was played until the girl walked out of the elevator, Qi Chuchen reached out and pressed pause.Stretch out your right hand to make gestures on the screen.

"There are just a few wall bricks next to the elevator door. The length of these bricks is usually a multiple of 5. When we were waiting for the elevator just now, I noticed that your height is a little bit higher than the fifth wall brick, and you are a little taller than me. , I am 1 meters, you should be in the early 79 meters. This brick should be 1*8 centimeters." Qi Chuchen pointed to Luo Zheyu, and then pointed back to the computer screen,

"The height of this person does not reach the upper edge of the fourth wall tile, so it feels like the difference is less than one-sixth? The distance is about two inches. The height is estimated to be about 1 meters." Qi Chuchen continued to press play, and he went smoothly Click fast forward.When the girl stood up and knocked on the door, she clicked pause again, and pointed to the position of her feet on the computer screen: "According to the 74 meters of shoes, this pair of high-heeled shoes should be stiletto heels of seven or eight centimeters by visual inspection. , without a water platform, this person is very thin, and wearing a 1-74 cm stiletto heel should increase the height by about 1-7 cm. The actual height of this person is less than 1 meters, which is about 68 meters. Gao Rui, Chen Jia’s information What is the height written in it?"

Gao Rui thought for a while, then took out his mobile phone and checked on the intranet, "1 meter 69." Qi Chuchen reached out and clicked the play.

At this time, the door of the monitoring room was pushed open, and a man in a black suit walked in: "Hello, officers, I am the property manager of the community."

Qi Chuchen didn't even turn his head, and waved his hand towards the door, "Go out and wait, I'll find you later."

The door opened and closed behind...

The surveillance video began to show a long period of unchanging scenes again. Gao Rui started to fast-forward, and after a while, it seemed that forty minutes had passed by the system time, and the door of Luo Zheyu's house opened again.The girl came out with a handbag hanging on her left wrist, and she was pinching a ball of toilet paper with half-closed palms.After closing the door with his right hand, Shi Shiran walked to the elevator and went downstairs.

…………

"Quickly rewind, fast forward, and write down the time when Chen Jia got out of the elevator and the time when he left." After Qi Chuchen finished speaking, he walked out of the monitoring room, walked to the outer office, pulled a chair and sat opposite the black suit.

"Property manager, right? How many doors are there in your community? How do you get in?"

"Comrade police, there is only one gate in our community. Both cars and people go through this gate. When people enter the gate, the door will be opened automatically after passing the verification of face recognition and fingerprint verification. For cars, the door will be automatically opened by recognizing the license plate. If visitors come, the owner must come out in person. Answer, otherwise the security will not open the door." The property manager replied.

"What about your employees? How do you use the elevators in your community?" Qi Chuchen asked.

"After employees join the company, they also enter their facial features and fingerprints, and entering and exiting the community is the same as the owners. For the elevator, because there are doors that require face and fingerprint recognition when entering the building, there are no additional settings for the elevator, and it works like an ordinary elevator."

"What is the size of the tiles pasted next to your elevator door?" Qi Chuchen asked again.

"Wait a minute, I'll check the information." The man in the suit went to the file cabinet and looked through it for a while, found a thick copy of the renovation contract, opened it and quickly looked through it.

"The wall tiles next to the elevator are a 45cm*45cm square."

"Your face recognition is quite advanced~~!!" Qi Chuchen said in a strange way.

"It is currently the best commercially available in the market. It is processed and recognized based on more than 80 points of the face. With infrared remote sensing, it is impossible to take a photo. Moreover, fingerprint recognition is added. In addition to the owner, the family members recognized by the owner, and property employees , to ensure that no one else will come in." The property manager introduced it seriously.

"Then I'm going to have plastic surgery, do you still recognize this machine?" Qi Chuchen couldn't help but directly asked the man disguised as a woman if he recognized it.

"It depends on how you do it. If it's the micro-surgery that is popular now, it's okay to use hyaluronic acid or cosmetic injections. If it's bone cutting and grinding, you may not recognize it. We haven't encountered this in detail, so we can't give it to you. Tell me exactly." The manager's words are very clear, the micro-adjustment system can recognize it, let alone makeup.It's just how did Chen Jia think of cross-dressing?Why do you want to dress up? ?

"Who is in charge of the facial recognition and fingerprint database entry, who manages the data, and what is the management method? Could it be leaked?" Qi Chuchen continued to ask.

"This is managed by me personally. Deleting and adding requires the authorization of the owner. Only when the owner passes the identity verification can I operate to add or clear data information. People other than the owner cannot apply for adding or clearing data." The property manager said.

At this time, Gao Rui had recorded the time in the notebook and walked out with the notebook.

"Okay, first delete two data for him." Qi Chuchen pointed at Luo Zheyu.

Luo Zheyu froze for a moment and instantly understood what Qi Chuchen meant.

"Then this gentleman, please come to this machine to verify your identity first." The property manager took Luo Zheyu to an office in the back.

Qi Chuchen thought for a while and followed in, and Gao Rui also followed.

The property manager asked Luo Zheyu to stand in front of a computer with an external camera. Qi Chuchen walked behind the property manager and watched him operate.

The property manager adjusted the external camera next to the computer to face Luo Zheyu, pointed to a fingerprint collector placed under the camera, and asked Luo Zheyu to press his fingerprint first, and after the facial recognition passed, the computer page automatically popped up Luo Zheyu's house number.The property manager and Luo Zheyu checked the room number, and when there was no problem, they clicked OK and entered a page with two pieces of information: one was added five years ago, and the identity was the owner.The other one was added after the Spring Festival, and the identity is a family member.

The property manager said: "You have a total of two pieces of identity data, one is yourself, and the other is your family members. Do you want to clean up the family members?"

Luo Zheyu hummed.The property manager clicked a few times on the keyboard, and pressed his fingerprints himself, and then told Qi Chuchen, "It cannot be recovered after it is cleared. After cleaning, this person will not be able to enter the gate again."

"You immediately find a lock repairer to change the lock, key, and fingerprints of the entrance door of his house." Qi Chuchen pointed to Luo Zheyu.

The property manager nodded and started making calls. After the call, he told Qi Chuchen: "It's arranged. In 10 minutes, the workers who change the locks will come over here. I'll take them for you. You can go home and wait."

"No hurry, just wait." Qi Chuchen took the notebook in Gao Rui's hand and turned it over.

As soon as the property manager heard the word "not in a hurry", his calf immediately twitched.
