【Death of a Lawyer-17】

Jiang Pingce remembered all the details since entering the examination room.

That night, after Yue Xingwen reported the case, the criminal police brigade was dispatched immediately. Due to the heavy rain, there were not many cars on the street, and the road was smooth. The police car honked its horn and headed to the scene of the crime at the fastest speed, and arrived at the Xinghe Building 10 minutes later.

Team Lin found the corpse hanging on the billboard on the third floor, simply asked Yue Xingwen a few words, and then led someone to knock on the door. After smashing the door for half a minute, a security guard came to open the door. The middle-aged man had gray hair and sleepy eyes. He was surprised when he saw a group of police officers, and he was very cooperative during the investigation.

From beginning to end, he behaved like a passerby who had nothing to do with the case.

The security guard's name is Zhao Cheng, and he is a very inconspicuous member of the security team hired by the Galaxy Group.

Team Lin later took him to make a transcript and asked him, "Do you know Zhou Ziyang?"

"I don't know," he said.

Team Lin asked, "Where are you tonight? Have you seen any suspicious people walking into the Galaxy Building?"

The security guard replied: "I locked the door on time at 22:00, and then took a nap in the duty room. Didn't I see anyone coming in?"

Team Lin quickly put him back, and Jiang Pingce didn't associate the case with him at all.

The initial investigation direction was Chen Yueqin and Qi Zhao, who were left in the building. One was the mistress of the deceased, and the other had a conflict with the deceased. Both had motives for murder.

Immediately after, Xingwen discovered that on the night of the incident, the details of "two elevators are on the first floor" of the Xinghe apartment across the street proves that someone has gone out. After finding Zhang Ronghua, a mysterious man who went out in the middle of the night, Fu Er behind Zhang Ronghua was involved. On behalf of the group of friends, they found out about the rape of Shen Haibin five years ago.

Everyone followed the clues, and finally found out to their surprise that the security guard who was ignored by everyone at first was actually the biological father of the victim of the Shen Haibin case five years ago!

Jiang Pingce looked at the photos on the computer and frowned: "He changed his name?"

Yue Xingwen said: "His current name is Zhao Cheng, not Zhao Jianming. He should have changed his name and ID card."

An adult can voluntarily change his name. If he calls Zhao Jianming directly, the building's daily "security duty list" will list the night shift security guard list and contact information. When lawyer Zhou sees the name "Zhao Jianming", he will think of ten. The case he represented a few years ago made him alert.

After changing his name, he was lurking in the Xinghe Building. As long as he didn't meet Lawyer Zhou directly, of course Lawyer Zhou would not doubt that a passerby security guard would have anything to do with him.

The security guards on night duty can walk around the building at will after locking the door of the Xinghe Building.

He can grasp the best time to commit crimes!

Ke Shaobin said: "We looked at the surveillance carefully. On the day of the incident, three maintenance workers went to the rooftop to repair the drainage pipes in the afternoon, and they came down in half an hour. After that, no one went to the rooftop. The surveillance only captured the scene of the deceased climbing on the rooftop. Since the security guard locked the door at 22 o'clock in the evening, he must have been on the rooftop after 22 o'clock, why did the surveillance not capture him?"

Security guards must remain in the duty room until the door is locked and cannot leave without permission.

Locking the door at 22 o'clock is the rule of the Galaxy Building. Zhao Cheng (Zhao Jianming) did lock the door at 22 o'clock that night. The monitor in the lobby on the first floor also showed him going to lock the door. After locking the door, he returned to duty. room.

If he committed the crime, he could only climb to the rooftop after 22:00.

Yue Xingwen thought about it carefully and analyzed: "The security guard must be very familiar with the environment of the building, and he is the easiest person to come into contact with. The deceased fell from the building at 0:00 in the morning, and I went downstairs with Senior Sister Lan and Senior Sister Lin. It took a lot of time to find the body in the rainstorm. At 00:15, I saw the body hanging on the billboard and called the police. At 00:30, the police rushed to the scene and knocked on the door for the security to open."

Yue Xingwen observed the Xinghe Building in the apartment across the street and saw that someone seemed to have fallen from the roof of the building. It was raining heavily and his vision was blurred. He couldn't rashly call the police until he found the body. What if his eyesight was dazzled?

Moreover, since the elevator stopped on the 1st floor when went out, it took a lot of time to wait for the elevator and cross the road. This resulted in a 30-minute window between Zhou Ziyang's death and the arrival of the police at the scene.

Jiang Pingce looked at Yue Xingwen: "In other words, he has 30 minutes to deal with the scene and destroy the evidence."

The two looked at each other and said tacitly, "Was he manipulated the surveillance?"

Security guards would see the surveillance in the duty room before the police had access to it. Thinking of this, Ke Shaobin immediately opened the surveillance folder of the Galaxy Building, found the picture captured by the camera installed in the stairwell on the 40th floor, opened the video, and quickly slid the mouse to around 22 o'clock in the evening, and asked, "You mean, Has this video been processed by him?"

Yue Xingwen nodded: "Let's not fast forward, let's play it over slowly from the beginning."

From 15:00 p.m. to 23:50 p.m., for 8 hours, no one passed the stairwell leading to the rooftop. Therefore, in this surveillance video, 99 were all empty stairwells, and there was no change at all. .

Whether it's the police or Ke Shaobin, it's impossible to keep staring at the blank monitor for 8 hours without a single second. In order to investigate the case efficiently, everyone is playing at double or even quadruple speed, and only pauses when a person appears on the screen. , slow playback.

Nowadays, everyone speculates that the monitoring may have been modified, and they simply stared at the screen from 22:00 for a second.

The picture has always been an empty stairwell.

22:30.

22:50.

There was no change in the picture, which made everyone's eyes sore, and nothing was wrong.

When I saw 23:01, suddenly, Jiang Pingce said in a low voice, "Go ahead for 2 minutes!"

Ke Shaobin froze for a moment, paused the mouse, and rewinded the screen for 2 minutes to start over. Jiang Pingce stared at the time bar in the upper right corner of the monitor, and saw that the time bar suddenly jumped from 23:01 to 23:03!

Yue Xingwen also discovered this, and immediately said: "The surveillance video was cut for 2 minutes!"

It was only a short 2 minutes. Since the screen was motionless, it was impossible to see it during fast-forward playback. You had to keep staring at the time bar to discover this subtle clue.

When the police investigated the case, because there were too many surveillance cameras copied back, it was impossible for everyone to watch it every second, and it would take a few days to watch it all.

The murderer has captured this mentality.

2 minutes of disappearing is the key!

Jiang Pingce said quickly: "Call out the monitoring of the two elevators and start watching from 22:00 in the evening."

Ke Shaobin quickly separated two windows and turned on the monitoring of the two elevators in Xinghe Building. From 22:00 onwards, he did not miss a minute and a second, and the two elevators remained motionless for a long time until 22:40. The time bar in the upper right corner of an elevator suddenly jumped from 22:45 to 22:47.

If you look at the picture, the elevator in the video still hasn't moved, and you can only find the loophole by staring at the time bar.

Ke Shaobin said excitedly: "The monitoring of the elevator has been missing for 2 minutes!"

This is also a detail they didn't notice at all when they fast-forwarded the playback.

Jiang Pingce said: "Call up the monitoring of the corridor on the 40th floor and start watching from 22:47."

Ke Shaobin found out the surveillance in the corridor on the 40th floor and played it from 22:47 onwards.

Now, the monitoring time bar has jumped from 22:47 to 22:49: "Another 2 minutes missing?!"

Yue Xingwen quickly took out a piece of paper and said while recording: "The elevators in the Xinghe Building are all express elevators. It only takes 2 minutes to run to the 40th floor and descend back to the 1st floor. At 22:45 that night, the murderer took the 1st floor. Elevator No. 1 went to the 40th floor, and he was photographed in the surveillance of the elevator, so he cut off the 2-minute surveillance."

Jiang Pingce followed: "At 22:47, the murderer appeared in the lobby on the 40th floor, and the surveillance in the lobby would also capture him. Therefore, the surveillance in the lobby on the 40th floor from 22:47 to 22:49 was also cut off."

Yue Xing Wen said: "The murderer is likely to hide in the men's toilet temporarily after he came to the 40th floor. The toilet is not monitored. At that time, lawyer Zhou and Chen Yueqin were intimate in the women's toilet. If he hid in the men's toilet, he would not be caught by these two. Personally found that the two were immersed in the excitement of cheating, and did not hear the slight footsteps in the toilet next door. The murderer climbed to the roof through the stairwell at 23:01, and the monitoring of the stairwell from 23:01 to 23:03 was the same. cut off."

The elevators, stairs, and corridors of the Galaxy Building are not monitored for dead spots.

So, why did the murderer not appear in the surveillance? Will he be invisible?

In fact, surveillance caught him. However, he erased all traces of his existence!

Only the security guard knows the location of all the surveillance cameras in the building, and can see himself from the surveillance records for the first time, and then cut off all the surveillance related to himself.

The surveillance video that was finally copied to the police was cut and processed by video software. Of course, the police could not find him from the surveillance!

No. 1 elevator, the 2-minute monitoring from 22:45 to 22:47 is missing;

In the lobby and corridor on the 40th floor, the monitoring of 22:47~22:49 is missing;

In the stairwell on the 40th floor leading to the rooftop, the surveillance from 23:01 to 23:03 is missing.

This is the trajectory of the murderer on the night of the crime.

Yue Xingwen handed the sorted timeline to his teammates, and everyone looked at each other in dismay.

In the massive surveillance video of the Galaxy Building, it is really hard to detect the missing few minutes if you are not careful, especially in the case of finding someone and playing at double speed, who would have noticed that the time bar in the upper right corner suddenly skipped2 minutes?

Yue Xingwen's meticulous analysis and Jiang Pingce's detailed observation skills finally found traces of the murderer's existence.

The two looked at each other and said, "It seems that we have to talk to this security guard in person." w, please keep in mind:,
