Escape From the Library

【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 few cars on the street, and the road was smooth. The police car blew its whistle and headed for the scene of the crime as quickly as possible, and arrived at the Xinghe Building in 10 minutes.

Team Lin found the corpse hanging on the billboard on the third floor, asked Yue Xingwen a few words, and then led someone to knock on the door.After knocking on 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 policemen, and he was very cooperative during the investigation.

From the beginning to the 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 Galaxy Group.

Team Lin later took him to take notes and asked him, "Do you know Zhou Ziyang?"

He said, "I don't know."

Team Lin asked, "Where are you tonight? Did you see any suspicious people walking into the Xinghe Building?"

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

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

The initial investigation was directed at Chen Yueqin and Qi Zhao who stayed in the building. One was the mistress of the deceased, and the other had conflicts with the deceased at work. Both of them had motives for killing.

Immediately afterwards, Xingwen discovered that on the night of the crime, the detail that "two elevators are on the first floor" in the Xinghe apartment across the street proved that someone had gone out. On behalf of the friend group, and then found out the rape case of Shen Haibin five years ago.

Everyone followed the clues, peeled off the cocoons, and finally discovered to their surprise——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!

Looking at the photos on the computer, Jiang Pingce frowned and said, "Has 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."

Adults can voluntarily change their name. If he is called Zhao Jianming directly, the building’s daily “security duty list” will list the list and contact information of the night shift security guards. When lawyer Zhou sees the name “Zhao Jianming”, he will think of ten The case that he represented years ago made him vigilant.

After changing his name, he was lurking in the Xinghe Building. As long as he didn't meet Lawyer Zhou head-on, Lawyer Zhou would certainly not suspect that a mere passer-by security guard had anything to do with him.

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

He can seize the best time to commit crimes!

Ke Shaobin said: "We checked the surveillance carefully. On the day of the incident, three maintenance workers went to the roof to repair the drainage pipes in the afternoon, and they came down in half an hour. After that, no one went to the roof. The surveillance only captured the scene of the deceased climbing up the roof. 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 didn't the surveillance camera capture him?"

Before locking the door, the security guard must stay in the duty room and cannot leave his post without authorization.

Locking the door at 22:22 is the regulation of Xinghe Building. Zhao Cheng (Zhao Jianming) did lock the door at [-]:[-] that night. There was also a picture of him going to lock the door on the surveillance in the lobby on the first floor. After locking the door, he returned to his duty room.

If he committed the crime, he could only climb onto the roof after 22:[-].

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 person most likely to be exposed to surveillance. The deceased fell from the building at 0 o'clock in the morning. I went downstairs with Senior Sister Lan and Senior Sister Lin. It took a lot of time to find the dead body in the heavy rain. At 00:15, I saw the dead body hanging on the billboard and called the police. The police rushed to the scene at 00:30 and knocked on the door for security to open."

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

Moreover, since the elevator stopped on the first floor when going out, it took a lot of time to wait for the elevator and cross the road.This resulted in a 1-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: "Has he tampered with the monitoring?"

Security guards will see the surveillance in the duty room before the police have access to it.Thinking of this, Ke Shaobin immediately opened the monitoring folder of Xinghe Building, found out the footage captured by the camera installed in the stairwell on the 40th floor, opened the video, 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 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 roof. Therefore, 99% of the footage captured by this surveillance is the empty stairwell, there is no Variety.

Whether it is the police or Ke Shaobin, it is impossible to stare at the blank surveillance for 8 hours without missing a second. For the efficiency of investigation, everyone plays it at double or even quadruple speed, and only pauses when people appear on the screen. , to play in slow speed.

Now, everyone speculates that the monitoring may have been modified, and they simply stared at the screen from 22 o'clock without missing a second.

The stairwell is always empty in the picture.

22:30 minutes.

22:50 minutes.

The picture without any change made everyone's eyes sore, and they didn't find anything wrong.

When I kept seeing 23:01, suddenly, Jiang Pingce said in a low voice: "Go forward 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 intently 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 noticed this, and immediately said: "The surveillance video was cut for 2 minutes!"

It was only a short period of 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 were investigating the case, because there were too many surveillance cameras copied back, it was impossible for everyone to watch it second by second. If you watched it like that for a few days, you would not be able to finish watching it.

The murderer just grasped this psychology.

The 2 minutes of disappearing is the key!

Jiang Pingce said quickly: "Call out the monitoring of the two elevators, and watch them from 22 o'clock in the evening."

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

If you look at the screen, 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 is missing for 2 minutes!"

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

Jiang Pingce said: "Call out the monitoring of the corridor on the 40th floor, and watch it from 22:47."

柯少彬将40楼走廊的监控找出来，从22:47往后播放，果然发现，监控的时间条，从22:47跳到了22:49：“又缺了2分钟？！”

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

江平策紧跟着说：“22:47，凶手出现在40楼的大厅，大厅的监控也会拍到他，因此，22:47-22:49的40楼大厅监控同样被剪掉。”

Yue Xingwen said: "After the murderer came to the 40th floor, he probably hid temporarily in the men's room. The toilet is not monitored. At that time, Lawyer Zhou and Chen Yueqin were intimate in the women's room. If he hid in the men's room, he would not be caught by the two men." Personally, I found that the two were immersed in the excitement of the affair, and did not hear the slight footsteps in the toilet next door. The murderer climbed up to the roof through the stairwell at 23:01, and the stairwell surveillance from 23:01 to 23:03 was the same was cut."

The elevators, stairs, and corridors of the Xinghe Building did not monitor blind spots.

So, why didn't the murderer appear in the surveillance?Could 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 at the first time, and then cut out all the surveillance related to him.

The surveillance video that was finally copied to the police was cut and processed by video software. Of course, the police had no way of finding him from the surveillance!

1号电梯，22:45~22:47的2分钟监控缺失；

40楼大厅和走廊，22:47~22:49的监控缺失；

40楼通往天台的楼梯间，23:01~23:03的监控缺失。

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

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

In the massive surveillance video of Xinghe Building, the missing few minutes are really hard to notice if you are not careful enough, especially when you are looking for someone and playing at double speed, who would notice that the time bar in the upper right corner suddenly skipped 2 minutes?

Yue Xingwen's meticulous analysis combined with Jiang Pingce's detailed observation ability 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."
