After Luke finished speaking, there were footsteps outside the door, and a tall man walked into the conference room with three of his subordinates.
Liu Fei quickly led everyone to welcome him out.
After a while of greetings, Liu Fei learned that the person who came to lead the team this time was a deputy director of the Technical Investigation Department, that is, the tall man named Zhang Tianzuo. He was an expert official with a doctorate. After Zhang Tianzuo arrived,
There was no day to stop, and he directly asked to enter the scene to check. Naturally, Liu Fei and others wanted to do so, and immediately took Zhang Tianzuo and others to the crime scene.
After entering the crime scene, Zhang Tianzuo carefully checked the situation at the scene, then took a miniature tester from several of his men and turned on the switch. After a while, when a series of English letters were displayed on the tester
Afterwards, Zhang Tianzuo was shocked, nodded vigorously and said: "Awesome, awesome, it is the latest toxin like phenyl ether, and it is also a synthesized version on site, master, master!"
Liu Xun also had some knowledge of this toxin, and quickly asked: "Director Zhang, you said that this toxin is actually a synthesized version on site. What's going on?"
Zhang Tianzuo stood up, pointed to the two pots of violets placed in the room and said, "Have you seen those violet flowers?"
Everyone nodded, and Zhang Tianzuo continued: "Those two pots of flowers usually look beautiful and charming, and have a strong fragrance, but when they encounter a colorless, odorless and non-toxic gas called benzene, those pots of flowers will
It will become a fatal killer. When the aroma of flowers and phenyl ether come together, a deadly poisonous gas similar to sarin gas, phenyl ether, will be generated. This gas is also colorless and odorless, but it can
It destroys people's central nervous system in an instant, causing people to die unconsciously. Have you seen the way those people died? The expressions before death still remain on their faces. This is the unique effect of phenyl ether!
This combination was discovered by a scientific research institute in the United States in August last year. Once it was announced, it caused a strong shock in the world. Later, two murder cases using this combination occurred one after another, so Interpol and Internet search engines
The company cooperated and deleted the news quickly, so not many people know this information. I didn’t expect that there are such masters who know this in Dongning City, it’s really not simple.”
Liu Xun asked: "Director Zhang, since phenyl ether can be fatal in an instant, how did the murderer escape? Did he just need to block his nose and he would be fine?"
Zhang Tianzuo shook his head slightly and said: "That's not possible. Phenyl ether can enter the body directly from the pores of the human body and spread quickly. Unless the murderer wears biochemical protective clothing, it will be difficult to leave calmly. However, there is an easier way.
A practical way to ensure that the murderer is not poisoned is to hold a piece of violet rhizome in his mouth when committing the crime. After returning home, he can use the rhizome to make a glass of water to drink, and there will basically be no problem!"
"Ah, so magical?" Everyone was shocked. Although the people from the Provincial Public Security Department had rich experience in handling cases, this was the first time they heard of such an unbelievable murder method.
Liu Fei immediately said to Liu Xun: "Liu Xun, you immediately take people to search Jiang Biao's office and carefully separate all communication tools and suspicious evidence!"
Liu Xun said with some worry: "Secretary Liu, is this...is this good?"
Liu Fei waved his hand and said, "Don't worry, I'm sure Jiang Biao is the murderer! All we lack now is evidence!"
Seeing that Liu Fei was so sure, Liu Zhen waved to Jiang Biao and others without hesitation, and rushed to Jiang Biao's office. At this moment, Jiang Biao was detained at the scene because he was a key suspect. He followed everyone and heard
After Liu Fei's instructions, his face immediately turned pale, but he quickly calmed down.
From the beginning to the end, the corner of Liu Fei's eye never left Jiang Biao's face. After seeing the change in his face, Liu Fei couldn't help but reveal a sneer on his lips.
More than twenty minutes later, Liu Xun rushed over with a group of his men. His expression was a little ugly. When he walked to Liu Fei, he only had a PDA in his hand, but nothing else!
"Secretary Liu, there is only one piece of equipment found at the scene. There is nothing suspicious about the others." Liu Xun said with a frown.
Liu Fei smiled and patted Liu Xun on the shoulder and said, "Don't worry, just give me the pda!"
After speaking, Liu Fei took the pda and connected it to the laptop with a data cable. He tapped the keyboard in his hand. Soon, all kinds of data and logs on the pda quickly fell out! Wait for Liu Fei to operate.
After finishing everything, he asked *** to print out various logs. Liu Fei's sharp eyes fell on Jiang Biao's face and said coldly: "Director Jiang, you are really a master hacker! Silent intrusion
I went to the database of the city bureau monitoring center server and deleted nearly 20 seconds of video recordings. All of this was done flawlessly!"
After listening to Liu Fei's words, Jiang Biao looked a little embarrassed. He said with a cold expression: "Secretary Liu, where did your words come from? How could I invade the monitoring center database! Do you have any evidence?"
Liu Fei said coldly: "The evidence is here, see for yourself!" After saying that, Liu Fei slammed the stack of log records printed out by the police and threw them in front of Jiang Biao and said: "Jiang Biao, yourself
Take a look! Don’t think that you are the only one who is a master hacker! In fact, you are still young!”
When Jiang Biao picked up the diary record that Liu Fei threw over and took a look, his face was pale and his hands were trembling. When he raised his head and looked at Liu Fei, his hands were already trembling and his voice was a little hoarse.
Said: "Liu Fei, how did you retrieve these logs? I have already erased all these records!"
When Jiang Biao asked this question, everyone basically knew that the real murderer was right in front of them, but how did Liu Fei find out? You know, Liu Fei is a layman! So,
Everyone turned their attention to Liu Fei.
Liu Fei glanced at Jiang Biao with disdain and sighed: "Jiang Biao, your technical level is considered to be one of the best in the entire Baiyun Province, not to mention Dongning City. It's a pity that you met me!
Even if your technical level is 10 times higher, you can't do it! The reason why I can tell that you are the murderer is because after watching the video surveillance footage, when you went to the scene of the crime, I carefully studied the video footage and found out that
The surveillance video lacked about 2o seconds of data. Following this clue, I found that a computer with an IP address of 192.136.1.132 had invaded the monitoring center server host. After asking the network administrator of the information center, I confirmed that this IP
The address is your computer. At this time, your computer happened to be on, so I followed the network and entered your computer. After some searching, I found that you are a very smart person. There is no information on your computer.
There is no operation record left, but a PDA remotely controls the server through your computer. I believe you must have found many reasons to explain why your computer shut down, but I can tell you clearly.
You, all this is in vain."
After Jiang Biao heard this, he smiled bitterly and said, "Then how are you sure that I am the murderer? You know, I was in the cinema at the time! Deputy Director Wu can testify for me."
Liu Fei sneered and said: "Huh, maybe you once entered the cinema with Deputy Director Wu, but I asked Deputy Director Wu before. Halfway through the movie, he remembered something and wanted to ask you for advice.
But I found that you were not in the movie theater. He was a very responsible comrade. He even searched the toilet in the movie, but he couldn't find you! Although you later went back after the movie was over, you forgot that although you
The remote control controls the spherical camera inside the municipal bureau to turn away when you climb over the wall, but you have forgotten one thing. The municipal public security bureau is very close to the intersection, and the intersection also has spherical cameras that rotate regularly for monitoring.
And the place you want to climb over the wall is exactly the surveillance range of that camera! After the period of time when my data was wiped, I immediately asked the traffic police team to monitor the intersection for 30 minutes near that period.
The video recording was sent to me! Take a look for yourself!" As he said that, Liu Fei took the laptop, clicked on a video, and after dragging a video forward, a short and fat man quickly flashed across the video screen.
Although the scene of the man climbing over the wall is not clear due to the distance, the body shape is very similar to Jiang Biao!"
Jiang Biao said coldly: "Liu Fei, you should know that there are no my footprints at the crime scene. Why do you say that I have been to the crime scene?"
Liu Fei sneered: "Liu Chen, are the people from the anti-smuggling team here?"
Liu Xun nodded and said, "We just called them here."
Liu Fei smiled and said: "Let them come in!"
Soon, ten members of the anti-smuggling team came in with ten German black shell dogs and reported to Liu Xun and Liu Fei one after another.
Liu Fei asked the members of the anti-smuggling team to command the police dogs to smell Jiang Biao's body, and then asked the members of the anti-smuggling team to take the police dogs to search for a pair of shoes with Jiang Biao's body odor! Half an hour later, a member of the anti-smuggling team took his
The police dog returned to the scene with a pair of shoes and placed the shoes in front of Jiang Biao.
At this time, Jiang Biao's face turned completely pale and his legs began to tremble.
Experts from the Provincial Department of Mechanical Investigation saw the pair of shoes and immediately said loudly: "Yes, it is the shoe prints of these shoes that have not found the owner."
Liu Fei glanced at Jiang Biao and said coldly: "Jiang Biao, what else do you have to say? Now you can explain who is the mastermind behind this matter!" n
