Mystery Case Tracing [Criminal Investigation]

"Comrade police, I really don't have permission to copy surveillance records to 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 the authority, call the authorized person to come over immediately. The police officer's ID has also been shown to you, and you have called to verify your identity. Now it is the police who is handling the case. Are you obstructing law enforcement?" Qi Chuchen pulled out from behind his waist. Handcuffs directly to the desk and patted "You want to interfere with official duties, I can just handcuff you away."

Gao Rui shivered beside him, always feeling that Brother Qi, who had returned from sick leave, had changed! Various roles are seamlessly connected. I used to be a gossip tabloid reporter, and now I am a domineering president. My temper was bad before, but now it is getting worse.

"Police officer! Then, can I call the leader right away? Soon, give me two minutes." The voice of the white shirt on duty was shaking 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 block the scene. When the time comes, a dozen policemen will be sealed, and the headlines of the major media tomorrow will be the front page of your community. It's big." Qi Chuchen casually pulled over an office chair and sat down, tilting Erlang's legs and shaking his feet.

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

"Police officer, I called our manager and he will come over right away. I can take you to the monitoring room now. You can watch whatever you want to monitor. Later, the manager will come over and copy it for you. Can you see it?"

Qi Chuchen waved his hand: "Go."

The white shirt Pi Diandian 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 the monitoring of the elevator exiting his door, all the monitoring records from Wednesday night to the present."

"C2802" Luo Zheyu said a room number next to him.

"Good, good." The staff knocked a few times on the computer in the middle, then turned to Qi Chuchen and said, "The police officer is alright. If you want to fast forward and rewind, press these two arrows. Pause and resume playback are all space keys. , Very simple". Qi Chuchen waved his hand to indicate that he could go out.

Gao Rui sat in front of the computer and started fast-forwarding monitoring: Most of the time the corridor was empty. Occasionally the elevator door was opened.

It was not until 11 o’clock on Friday morning that the elevator door opened again, and a young girl came out: her shoulder-length hair was slightly curly, with light make-up, and curvy willow eyebrows. She looked very white and delicate, with double eyelids and eyelashes. He is very cocked, with big eyes, painted with bean paste color lipstick; wearing a high-neck linen long-sleeved tight-fitting gauze, the hem is tucked into a plaid skirt, a pair of flesh-colored silk stockings on his legs, and a pair of **** high heels on his feet. Carrying a dark red one-shoulder small satchel, nails are also painted big red.

Qi Chuchen stretched out his hand and paused, 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 blank space, and the monitor continued to play.

The girl walked out of the elevator, walked to the door of Luo Zheyu's house, knocked on the door a few times, and then rang the doorbell again. After waiting for half of the payment to see that no one was opening 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 and took out a pair of slippers to put on, took out the key from the bag and opened the lock, and pressed his fingerprints. .

The door clicked open. Three people were shocked! !

"Chen Jia." Luo Zheyu's voice was incredible.

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

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

When the girl walked out of the elevator, Qi Chuchen reached out and paused. Extend your right hand to make gestures on the screen.

"There are just a few wall bricks next to the elevator door. The length of this brick is usually a multiple of 5. Just now when we were waiting for the elevator, I paid attention to it. Your height is a little bit higher than the fifth wall brick. You are a little taller than me. , I’m 1.79 meters, you should be in the early 1.8 meters. This brick should be 45*45 cm." Qi Chuchen pointed to Luo Zheyu, and then pointed back to the computer display.

"This person's height is not up to the upper edge of the fourth wall tile, and I feel that it is less than one-sixth? The distance is about two inches. The height is estimated to be about 1.74 meters." Qi Chuchen continued to press play, smoothly. Click to fast forward. When the girl stood and knocked on the door, she clicked the pause again, and pointed to the foot position on the computer screen: "Calculated by wearing shoes of about 1.74 meters, this pair of high heels should be seven or eight centimeters of stiletto. Without a water platform, this person is very thin. Wearing a seven-eight-centimeter stiletto heel should increase the height by about five or six centimeters. The actual height of this person is less than 1.67 meters, which is about 1.68 meters. Gao Rui, Chen Jia What's the height written in it?"

Gao Rui thought about it, then took out his mobile phone and checked the intranet. "1 meter 69." Qi Chuchen reached out and clicked to play.

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

Without turning his head back, Qi Chuchen waved his hand outside the door, "Go out and wait, I'll look for you later."

The door behind you opened and closed...

Surveillance video began to remain unchanged for a long time. Gao Rui started to fast forward and fast forward for a while. Seeing that the system time should have passed forty minutes, the door of Luo Zheyu's house opened again. The girl walked out and hung a handbag on her left wrist, holding a toilet paper ball in her palm. Close the door with his right hand, Shi Shiran walked to the elevator and went downstairs.

...

"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, went to the outside office, pulled a chair and sat down opposite the black suit.

"Property manager, right? There are several doors in your community, how do you get in?"

"Comrade police, there is a gate in our community, where cars and people go through this gate. People entering the door are automatically opened after facial recognition and fingerprint verification are passed, and cars are automatically opened by recognizing the license plate. If visitors come, the owner must come out in person. Otherwise, the security will not open the door." The property manager replied.

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

"After employees enter the job, they also enter their facial features and fingerprints. Entering and leaving the community is the same as the owner. When entering the building, there are also doors that require facial recognition and fingerprint recognition. Therefore, the elevator is not equipped with extra settings, and is used the same as ordinary elevators."

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

"Wait a minute, I will check the information." The man in a suit walked to the file cabinet and looked through it for a while, found a thick decoration contract, opened it and flipped it quickly.

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

"You face recognition is quite advanced~~!" Qi Chuchen said with a strange yin and yang.

"It is the best commercially available on the market. It is processed and identified based on more than 80 points of the face, with infrared remote sensing, and it is impossible to take a photo, and with fingerprint recognition, in addition to the owner, the owner’s family members, and the property Staff, guarantee that no one else will come in." The property manager introduced it seriously.

"Then I'm going to have a plastic surgery, do you still recognize this machine?" Qi Chuchen is not good to directly ask if the man pretends to be a woman.

"It depends on how you do it. If it’s the popular micro-surgery, it’s okay to apply hyaluronic acid or cosmetic injections. If it’s bone grinding and bone grinding, you may not recognize it. We haven’t encountered this in detail, so we can’t give it Tell me exactly." The manager's words are very clear, the micro-integration system can recognize it, and makeup is not a big deal. Just how did Chen Jia think of the change? Why do you want to change clothes? ?

"This facial recognition, fingerprint database who manages the entry, who manages the data, and what is the management method? Is it possible to leak?" Qi Chuchen continued to ask.

"This is managed by me personally. Deletion and addition require the owner's authorization. Only the owner passes the identity verification before I can add or clear data. There is no way for anyone other than the owner to apply for adding or clearing data." The property manager said.

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

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

Luo Zheyu was stunned for a moment to understand what Qi Chuchen meant.

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

Qi Chuchen thought about it and followed in, and Gao Rui also followed in.

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, pointing to a fingerprint collector placed under the camera, and let Luo Zheyu press his fingerprint first, and then after the facial recognition passed, the computer page automatically popped up. Luo Zheyu's house number. The property manager and Luo Zheyu checked the number of the next house. After 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 is added after the Spring Festival, and the identity is family.

The property manager said: "You have a total of two pieces of identification data, one for yourself and the other for your family. Should you clean up the family member?"

Luo Zheyu hummed. The property manager clicked a few times on the keyboard, pressed his fingerprint again, and then told Qi Chuchen, "After the cleaning, it is irreversible. After the cleaning, this person cannot enter the door again."

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

The property manager nodded and started to call. After the call, he told Qi Chuchen: "It's arranged. After ten minutes, the worker who changes the lock will come over here. I'll take it 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, his calf twitched.
