Serious Crime Unit 1

Chapter 245 Not at the scene (18)
When Lu Yingying saw 00:13, the screen suddenly shook. Lu Yingying thought she had seen it wrong, because staring at the video for a long time would make her eyes and spirit tired, and sometimes she would have an illusion.So she rewound the video and watched it again. The screen was still shaking. Lu Yingying felt something was wrong and said to Jiang Yiming: "Captain Jiang, the video may have been tampered with or hacked."

"Has it been tampered with? Is there someone inside?"

"It is possible, but even without a mole, the video can be tampered with. As long as they invade their surveillance system and replace the real video with the fake video, then the real culprit who helped Wang Cailai escape can boldly enter and exit this door. Because the hospital monitors The system’s firewall level is not high, and ordinary hackers can destroy the firewall and tamper with the video.”

"So the person who ordered Wang Cailai to escape is the original culprit?"

"Not necessarily. The original culprit may have paid hackers to hack into the surveillance system."

"What happened should be like this: the original murderer first used anesthetic to charm the male nurse, then came to the iron gate, entered the password, entered the ward, then entered the ward, took Wang Cailai away, and took a car to Room 204, Feicui Building, Golden Harbor Community kill?"

"Yes, you can reason like this."

"How did the original culprit know the password to open the door?"

"It's too easy. You can know the password accurately by hiding secretly and watching the doctors' actions when entering the password. Because the password is only 4 digits, not to mention there are more than twenty doctors and nurses, it is easy to get it from them. password."

"It's less than three kilometers from the mental hospital to the Golden Harbor Community. There are surveillance cameras all the way. It shouldn't be difficult to find the murderer, right?" Jiang Yiming said confidently.

"It stands to reason that this is the case, but the criminal IQ of the original murderer is very high. I have never heard of him using a mentally ill person to kill people and steal money. Therefore, we may not be able to successfully catch him." Lu Yingying is not optimistic.Jiang Yiming nodded and fell into deep thought.

Lu Yingying took the hard drive storing the video back to the criminal police team and used software to identify it. It turned out that the video had been replaced for half an hour, and the original murderer had enough time to complete the task.

Lu Yingying and Xiao Ke came to the Provincial Mental Hospital again, called up the video at the entrance of the hospital, and tried to find out the person who took Wang Cailai away from the video, because the hospital is surrounded by 3.5-meter walls on three sides, and outside the wall is a bustling street, even in the middle of the night , there are a lot of people and cars, and there are surveillance cameras all around. The culprit who took away Wang Cailai would not be stupid enough to climb the wall and get in.

The time when the fake video was replaced is from 0:13 to 0:43, so you should start viewing it from 23:00. Under normal circumstances, the original culprit will not enter the hospital before 23:00, because the hospital has security patrols. The longer you stay in the hospital, the greater your risk of being discovered.

When the video was played to 24:00, a short man appeared on the screen. He wore a peaked cap, a pair of wide sunglasses on his face, a black sportswear, and a figure-eight gait.He kept his hat low on purpose so that it would be difficult for the monitor to get a clear picture of his face.He walked out from the left side of the screen, walked towards the hospital door on the right, and then disappeared from the screen.Based on Xiaoke's many years of experience, he judged that this person was very suspicious.

Xiao Ke and Lu Yingying pulled up the surveillance video of the hospital corridor, and the suspect appeared in the picture again.He walked into the corridor from the left side of the lobby, which is the door of the ward. Because there was only one light on in the corridor, the light was dim, and the suspect's footsteps were very fast, and he disappeared in a blink of an eye. It was impossible for the security guard watching the surveillance. Staring at the monitor screen every second, even if the suspect is seen by the security guard, he will think that he is in the wrong place because the ward door is locked, and the suspect will automatically turn around.

Xiao Ke asked the security guard and the dean if they knew this person?They said they had never seen it.They continued to watch the video and found that the suspect walked from the other end of the corridor at 00:40, followed by Wang Cailai. They walked toward the door together and then disappeared from the left side of the screen.

The fake video used by the suspect was removed at 00:43.This made Xiao Ke wonder: "Yingying, the suspect left the hospital at 00:40, so how did he remove the fake video?"

"It's very easy to remove the fake video. You can use a laptop anywhere with a wireless network outside the hospital to crack the firewall of the wireless network, and then invade the hospital's monitoring system. Then even hackers in the United States can remove the fake video on time." Lu Yingying told Wishful He blinked his left eye, as if laughing at him for being behind the times.

Xiao Ke ignored her: "Why is the hospital's firewall set at such a low level? Can't a high-level firewall be set up?"

"Is the firewall on German Chancellor Merkel's mobile phone advanced enough? Isn't it being arbitrarily eavesdropped by the CIA?"

"So there is no unbreakable firewall in the world?" "Theoretically, that's true."

"Your network skills are so good, can you quickly find the suspect?"

"Of course, it's just a matter of time, unless he grows wings and flies into the sky, or absconds."

"I...it's great that we have you!" Xiao Ke raised his thumb to her. Xiao Ke wanted to say: It's great that we have you.I thought it was a bit disgusting to say this, so I changed my mind.Lu Yingying is so smart, of course she understands what he wants to say, and she is secretly happy.

Lu Yingying once again published a series of articles about Wang Cailai on the Internet; she continuously broadcast Wang Cailai's photos and reward advertisements on TV.She took screenshots of the video of the short suspect and used the "FotoSoft" software to process it clearly. However, she tried several times and spent an entire afternoon without achieving the desired results.

After comparison, Lu Yingying determined that the suspect was about 153 centimeters tall, weighed 40 kilograms, and was between 40 and 45 years old. This narrowed the scope of the suspects a lot, saving a lot of time and police effort.

Lu Yingying posted blurry photos of the suspect online to launch a reward series. Although the public could only see a rough outline of the suspect, the suspect's relatives and friends should be able to recognize him, and she could not let go of any opportunity.

Jiang Yiming called Lu Yingying to have a meeting.She put down what she was doing, walked into the conference room, saw everyone there, smiled at Jiang Yiming, and then sat on the third chair at the O-shaped conference table. This was her default position because she was the last one to enter. Serious Crime Team No. 0, this person turned out to be the deceased Zuo Li. This person often reminded her to sacrifice for justice like Zuo Li at any time!
"I already know the results of Xiaoke and Yingying's investigation. Lao Wu, please tell me about the investigation with Zhou Ting." Jiang Yiming said.

"We checked the surveillance video at the entrance of Jade Building. The video showed that Wang Cailai entered the Jade Building at 5:4 on May 01. He also opened the iron gate smoothly. This shows that he had an inside job because he did not press the button when entering. There was no doorbell or key to open the door. At 50:03 in the morning, he came down from Feicui Building with nothing on him, indicating that he had not robbed a large amount of money. There is one thing I can't explain: Judging from the shoe prints extracted from the scene, the murderer's The weight is still about 00 kilograms, but Wang Cailai only weighs 100 kilograms, what a heck!" Wu Jiang said.

"Judging from the angle of the stab wound on the deceased, the murderer was at least 185 to 190 centimeters tall. How could it be Wang Cailai?" Luo Jin said.

After listening to the conversation between Wu Jiang and Luo Jin, Lu Yingying suddenly had a flash of inspiration and said excitedly: "I know why, it should be like this: the original culprit trained Wang Cailai for a long time. Everyone knows that dogs with low IQs are trained by their owners. , will act as a killer and bite people to death. Then, after Wang Cailai, whose IQ is many times higher than that of a dog, was trained by the original murderer, he used him to kill people and steal money. This is not difficult to do. Because mentally ill patients also understand emotions, and he regards the master's orders as It is his duty, but he does not know right from wrong, so he will be used by the original murderer. The original murderer is not sure that Wang Cailai is qualified for the killing task, and he must be foolproof, so he avoids the monitor, climbs to the rooftop, and comes to Feng Linghe The door of the unit where He Xiaoya lived was opened from the inside, allowing Wang Cailai to enter. Then he returned to Feng Ling and He Xiaoya's door. The original murderer sat on Wang Cailai's shoulders, tricked them into opening the door, and threatened them with a dagger. The money was handed over, and after getting the money, Feng Ling and He Xiaoya were killed. Because the original murderer was only 153 centimeters tall and weighed about 40 kilograms, Angkor judged that the murderer weighed about 100 kilograms. Luo Jin judged It is true that the murderer is over 185 centimeters tall, so the original murderer will not leave shoe prints at the scene."

"Yingying. Your reasoning is too imaginative." Zhou Ting found it incredible.

"Yingying, you are so flattering, your reasoning is very correct!" Wu Jiang strongly supported her.

"But how did the original culprit get into Feng Ling and He Xiaoya's rooftop?" Zhou Ting asked.

"The original murderer was as light as a swallow. If he practiced climbing for many years, he could climb to the rooftop without ropes and only with the help of water pipes, security windows and the like. Have you ever heard of Spider-Man? A French man, Alain Robert, used his bare hands Climbing the Petronas Towers in Kuala Lumpur and making headlines in major media, he became the people's hero. This is the so-called Spider-Man." Lu Yingying said.

"If this is true, the original culprit is too clever."

Just as he was talking, Jiang Yiming's cell phone vibrated on the table. He saw it was a stranger's number and wanted to hang up and continue the analysis and discussion, but he felt it was inappropriate. Maybe the insider called his office and no one answered, so he called him. cell phone, so he slid open the answer button and asked who the other party was?The other party said he knew where the suspect Wang Cailai lived.Jiang Yiming told him not to go away, and they would arrive immediately.

Jiang Yiming asked Luo Jin to look after the house, and the others followed him. Everyone stood up, went to the safe to get guns, and prepared to set out to arrest Wang Cailai.
