Criminals will always leave traces, and the job of the police is to look for such traces, and then follow the clues to uncover the group of gamblers. Before finding out the truth and bringing the perpetrators to justice, the work done by the police
It is often boring or even meaningless, but they have to do it.
Xu Lang is sometimes very lucky. He is lucky to live in this era of rapid technological development. The most practical and helpful thing for the police is the application of the Sky Eye system. In the past, when the police handled cases, they often could only use the evidence at the scene and add evidence.
People's testimonies and memories can be used to deduce the perpetrator's entire crime process. If we want to truly bring the perpetrator to justice, we need to rely on a lot of other evidence to prove the restored scene. But now, everyone is different.
In the city, in every public place, and even at home, everyone is under surveillance. However, people have gradually become accustomed to it, and even ignore the existence of the Sky Eye. If you want to find the perpetrator, surveillance is the most effective way.
A good helper, monitoring is often more credible than witness, because it cannot lie, but people can.
Wang Guofu had already asked people to do the work of searching for witnesses and taking confessions after arriving at the scene. This is the most basic thing. Wang Guofu is an old policeman and he knows this very well. What Xu Lang wants to do now
I just went to see the monitoring center at the nursing home.
Such a bloody murder occurred in the nursing home, and the dean appeared immediately. After Xu Lang was kicked out by Fan Yang, the dean found Xu Lang, held Xu Lang's hand, and said something harmless.
Mandarin, and Xu Lang hated it very much.
"Dean Qian, I want to take a look at the monitoring of your nursing home, is that okay?" Xu Lang interrupted the dean's chatter, which was all nonsense, and said.
"Yes, of course. It is the obligation of every citizen to cooperate with the police in handling cases." Dean Qian said with a smile.
Xu Lang took a deep look at Dean Qian and motioned for him to take him there. Dean Qian didn't say any more nonsense and personally took Xu Lang to the monitoring room of the nursing home.
The monitoring room of the nursing home is in a room in the corner of the first floor. The room is not big, but there are several monitors. There are two uniformed employees inside, who should be responsible for watching the monitors.
When Xu Lang and the others pushed the door open, there were three people in the room. They were playing poker in the middle of the room. When they saw Xu Lang and the others come in, they quickly stood up and put away the playing cards.
The dean, who was smiling just a second ago, suddenly turned gloomy after seeing the behavior of these three people. He first glanced at Xu Lang, and then cursed at these three people.
After hearing a few words, Xu Lang became a little impatient and asked directly: "Where is the surveillance on the fifth floor? I need to check."
"Why don't you hurry up and help this police officer find him."
Dean Qian kicked one of the young men in the butt and scolded him.
The young man quickly ran over, came to a monitor, and started operating it, while Xu Lang was standing next to it.
After the other party brought up the surveillance on the fifth floor, Xu Lang patted him on the shoulder and motioned for him to get out of the way. Xu Lang sat down and started to watch the surveillance.
The other party called up the surveillance at six o'clock this morning. Xu Lang looked at it for a while and found that during this period, no one entered Ward 513, but in the corridor, many people did pass by. Among them,
Most of them are family members of patients, and some are patients and medical staff.
Xu Lang started to fast forward and quickly checked the monitoring.
After about half an hour, Xu Lang saw Li Xiong and a female nurse starting their rounds from the top ward on the fifth floor. They stayed in each room for a short time, only about five or six minutes.
When Xu Lang saw Li Xiong and the others, he looked at the time on the monitor. It was 10:57, which basically matched Li Xiong's statement that they usually did ward rounds at 11 o'clock.
Xu Lang started to fast forward again. This time, about five minutes later, Xu Lang saw Li Xiong and the female nurse entering Ward 511. After about three minutes, the female nurse came out alone. She went first
After about two minutes in Ward 512, the female nurse came out, and then she entered Ward 513.
About a minute after the female nurse entered Ward 513, Li Xiong ran out of Ward 511, first went to Ward 512 for a look, and then came to Ward 513.
Not long after Li Xiong entered Ward 513, he walked backwards out of the ward, and then shouted something loudly in one direction. According to the direction he was looking and the location of the probe, that should be the infirmary.
Sure enough, after Li Xiong called, about thirty seconds later, two female nurses ran over, and the three of them entered Ward 513 again. At this time, many people appeared in the corridor, all from other wards.
Hearing the noise, he walked out of the ward to check the situation.
Not long after Li Xiong and his party entered Ward 513, they carried a person out. Based on the clothes the person was wearing and the face that flashed past, she was the female nurse who entered Ward 513 first.
As Li Xiong and the others appeared again, more and more people were in the corridor. Many people gathered towards the door of 513. Xu Lang even saw two people walking into ward 513. However, these two people did not go in for much.
After a long time, they ran out in a panic. One of them even fell down when running out of the ward. Obviously, they saw something terrible in the ward.
At this time, Li Xiong and the others were not in Ward 513. After these two people entered the ward and were scared out, no one ever entered the ward again.
After about five or six minutes, Li Xiongcai came to the door of ward 513 while talking on the phone, closed the ward door, and then said something to the onlookers, seeming to be explaining something, and also seemed to be persuading something.
However, no one at the scene left, but looked at the door of Ward 513.
After about fifteen minutes, Wang Guofu and the others arrived at the scene. Not long after Wang Guofu and the others entered the scene, Wang Guofu walked out and made a phone call, probably to Xu Lang. After that, they were Xu Lang and Qin Mingyue.
The figure appeared in the surveillance.
After watching this piece of surveillance, Xu Lang frowned.
Judging from this surveillance video, the first person to enter Ward 513 was the female nurse, and the second person to enter the scene was Li Xiong, followed by two medical staff from the nursing home, and then two young people watching the excitement.
When Xu Lang was watching the surveillance, he discovered that the two young men had come out of Ward 511, and the last ones to enter the ward were the police.
The video was very long. Xu Lang only took a brief look at it, but he didn't see anything suspicious. However, judging from the time of the surveillance video, Li Xiong did not lie, and Ai Chengcheng did it when the female nurse entered.
He died in the ward before. If he wanted to know whether Ai Chengcheng was killed, he could only watch the surveillance video in front of him. So, Xu Lang asked someone to pull up the surveillance video in front of him.
While Xu Lang was watching the surveillance video, Dean Qian received a call, said a few words and then left. It should be a call from the media. He needed to deal with it, but Xu Lang did not stop him.
In fact, when it came to checking the surveillance video, Xu Lang took the video back and left it to Lu Xing. However, Lu Xing had never rested since he was concerned about the murder case. A few days ago, Lu Xing was still working overtime.
He carefully checked the videos around the scene of Zhao Junyi's murder. Although Lu Xing was not directly involved in the subsequent series of cases, his help was still needed on some suspicious and problematic videos. It can be said that during this period,
, the hardest one is Lu Xing.
Now, Ai Chengcheng has been killed, and his body has been taken back by Qin Mingyue for autopsy. Wang Guofu's people have already done the investigation, interviews, looking for witnesses, and taking confessions. Xu Lang can't enter the crime scene now.
, there are no new clues for the time being, so Xu Lang can only do this.
Xu Lang started watching it at nine o'clock last night.
At about nine o'clock, there was no one in the corridor on the fifth floor. Occasionally, people passed by, including family members or nursing staff from other wards. No one entered or left Ward 513.
However, at nine-thirty, the female nurse whom Xu Lang saw before began to check the wards. This time, she was alone. She started from the ward at the top of the corridor. Compared with what Xu Lang had seen before,
Ward rounds, this time, the female nurse rounds the wards very quickly. Basically, she goes in to each ward to take a look, then comes out, and continues to the next ward.
When the female nurse entered Ward 513 and came out, Xu Lang's eyes narrowed subconsciously.
Before, the female nurse did not come out during her ward rounds, but this time, when the female nurse came out of ward 513, there was another person following her.
This person has her back to the camera, but based on her body shape and the clothes she is wearing, she is a woman, and she should be the caregiver of Ai Chengcheng that Li Xiong mentioned.
After the woman sent the female nurse out of the ward, she did not return immediately. Instead, she watched the female nurse enter other wards before she returned to the ward.
After about seven or eight minutes, the female nurse looked at all the wards, and then she returned to the infirmary. After the female nurse left, about twenty minutes later, the door of Ward 513 was opened again from the inside.
It opened, and a woman came out. She was holding a bag in her hand. The bag was translucent. Inside was an insulated bucket. She also carried a bag in her other hand. The woman was wearing a mask.
After walking out of the ward, she turned around and said something to the ward.
The woman stood at the door for about a minute, then she closed the door, turned and left.
Until the woman disappeared from the surveillance screen, Xu Lang didn't see the woman's face clearly, which made Xu Lang frown.
The feeling this woman gave Xu Lang was that she was deliberately avoiding the surveillance cameras from photographing her, or her appearance, until she reached the location of the surveillance cameras.
When she came out for the second time, the woman always turned her back to the camera. Even when she turned around to talk to people in the ward, she turned around from the side facing away from the camera. When leaving the corridor,
She did not take the elevator very close to Ward 513, but took the stairwell that could not be captured by the surveillance cameras, which had to make Xu Lang suspicious of her.
Although Xu Lang was confused, Xu Lang continued to check the video footage.
Next, for a long time, no one appeared in the video. Occasionally, one or two people came out of other wards.
Someone approaches Ward 513.
Xu Lang speeded up the video playback speed again.
Soon, the time shown on the video reached two o'clock in the morning today, and at this time, no one had appeared in the corridor for a long time. Just when Xu Lang thought there would be no clues, a figure appeared.
This person came out of the stairwell. He was wearing a black sweatshirt, and it was also a sweatshirt with a hood. The other person put the hat on his head, covering half of his face. On his face, he also wore a
He was wearing a mask, and he was holding a tool box in his hand, which was similar to the medical box that medical staff in hospitals carry when they visit patients. Judging from his body shape, he was a man.
The man was 1.75 meters tall. After he appeared in the stairwell, he did not move immediately, but looked around very vigilantly. The first place he looked was in the direction of the medical room, where the staff on duty rested.
After confirming that there was no one, the man looked at other wards. After confirming that there was no one, the man took action. He went straight to ward 513 and pushed the door open.
After the man entered Ward 513, he didn't come out for a long time. Xu Lang started to speed up the video playback again.
The man appeared at 2:18 in the morning, which is when people are sleepy. After speeding up the video playback speed, Xu Lang discovered that the man appeared again around 5 in the morning.
According to the surveillance footage, when the man appeared again, in addition to the toolbox he had brought with him, he also had a large black plastic bag in his hand. Xu Lang came closer to the screen, looked at it for a while, and found the bag.
It should contain clothes and the like, and the man was still wearing black clothes. However, after Xu Lang stared at the other man's clothes for a long time, he discovered that the black sweatshirt the man was wearing was not the same one before.
It was a new sweatshirt, because Xu Lang saw the tag hanging on the back of his neck. Obviously, this was a new set of clothes, but their colors and styles were exactly the same.
It's hard to spot if you don't look carefully.
Seeing this, Xu Lang looked again at the black plastic bag in the man's hand. It should contain the clothes he was wearing when he arrived.
At 5:23, the man opened the door of ward 513. He first stuck his head out and looked around, but found no danger. Then, he quickly walked out of the ward. Before leaving, he turned around and closed the door.
The door of the ward was left.
After the man left the ward, he left through the stairwell just as he came in.
"Snapped."
Just when the man was about to disappear from the surveillance screen, Xu Lang seemed to have discovered something. He suddenly pressed the pause button, then enlarged the screen. Then, he brought his whole face close to the screen and looked at the man on the screen.
The left hand is only infinitely magnified.
When the man first appeared, he had gloves on his hands. When he walked out of Ward 513, he also had gloves on his hands. However, when he was about to leave the surveillance screen, Xu Lang discovered that he had
The glove on his left hand was taken off, and at this moment, Xu Lang saw something, something he was very familiar with and often appeared in his dreams.
tattoo.
Yes, that's right, it's a tattoo. The location of the tattoo is between the tiger's mouth and the index finger of his left hand. Although the picture became blurry and grainy after being enlarged many times, Xu Lang still had difficulty identifying it.
What kind of tattoo is it, scorpion tattoo.
The body is small but the tail is a big scorpion tattoo. Xu Lang is not unfamiliar with this tattoo at all, but is extremely familiar with it. It is a unique tattoo and a unique symbol of members of the organization 'Master Chang'.
A few years ago, when Xu Lang and the others were investigating the Chengxi Orphanage case, they relied on this tattoo and discovered a lot of truth. Finally, after the case was over, Xu Lang thought that the scorpion tattoo was just made by Ouyang Jing and the others. However,
It was later discovered that in addition to the people in the orphanage, other members of the 'Master Chang' organization also had it. Now, when Xu Lang saw this tattoo again, his mood was very complicated and his breathing became rapid.
.
After seven years, Xu Lang saw a familiar tattoo again, and this tattoo represented 'Master Chang'. In other words, the person who appeared in the nursing home and entered Ward 513 was organized by 'Master Chang'
Man, then, who is this man? What is his status in the 'Master Chang' organization? Why does he appear here and brutally kill Ai Chengcheng?
This series of questions emerged in an instant, and Xu Lang was a little confused.
Judging from the information Xu Lang had on the members of 'Master Chang' before, people with scorpion tattoos between the tiger's mouth and index fingers do not have a high status in the 'Master Chang' organization. Generally, people with high status,
Their tattoos are not on their hands, which means that this man may be just a pawn, or in other words, he is just a killer.
Xu Lang is concerned about why Master Chang's people appeared in the nursing home, and why he wanted to kill Ai Chengcheng. Ai Chengcheng is already a disabled person and can only spend his whole life in bed and wheelchair.
, such a person should not pose a danger to the 'Master Chang' organization. Is it possible that Ai Chengcheng is also a member of the 'Master Chang' organization?
