That night, Jun Tang worked overtime in the company until morning 1, and then hurried home. He lives in the single dormitory of the municipal electric wire factory, which closed down due to poor management, and this dormitory was rented out by the factory in exchange for the living expenses of the employees.
In front of the dormitory is the gate, which is also the back door of the electric wire factory. It is closed all the year round, and Jun Tang comes in and out from here every day. He went to his door on the fourth floor in the dark, just took out his key, and suddenly heard a "dong" sound from downstairs, and then someone shouted, "thief, catch thief-"
Jun Tang was surprised, turned his head and looked downstairs. There were two swaying figures in the corridor on the second floor, and he immediately ran downstairs. When Jun Tang ran to the second floor, two shadows had reached the first floor, and he hurried down to the first floor. On the first floor, a young man in vest and shorts is walking around and looking around. Jun Tang recognized Zhu Zizhen who was renting on the second floor. Zhu Zizhen turned to look at him, pointed to the gate and said loudly, "Where did you escape?" Tang Junchao looked in the direction of Zhu Zizhen's finger. Sure enough, he saw a black shadow flash across the gate.
Urgent, two tandem quickly ran past. There is a road outside the door. A taxi is parked on the side of the road. A middle-aged couple stood by the car. This man is counting money for the driver in the car. In addition, there is no one else.
Strange, the thief has disappeared! Zhu Zizhen went over and asked the couple, "Excuse me, did you just see a man running out of the gate?"
"I didn't see anyone running out." The woman replied.
The man asked, "What's the matter?"
Zhu Zizhen said, "A thief has escaped. Where did this guy go? "
Jun Tang stood there, very different. He and Zhu Zizhen followed. As long as thieves have no wings, it is impossible to disappear from their eyes in a few seconds!
Not finding the thief, Jun Tang and Zhu Zizhen walked slowly to the dormitory. Zhu Zizhen said, "I was awakened by a bubble of urine when I was sleeping. As soon as I opened the door, I heard something moving next door, and then I saw a man running out. " As soon as he saw me, he turned and ran, and I immediately chased him down. "
"Are you next door?" Jun Tang wondered, "Why didn't he chase the thief?" Zhu Zizhen said, "I don't know. Ask him. "
Two people on the second floor, there is a door wide open, dark inside. Zhu Zizhen said, "That's it. Is he still sleeping? " Jun Tang reached out and knocked on the door and said, "Hello! There are thieves in your house. " There's no one talking inside.
Zhu Zizhen stretched out his hand and touched the switch by the door. 1 of "pa", the light came on. I saw an iron drum lying on the ground in the middle of the room and a man lying on the bed. Both of them were surprised, looked at each other, walked into the room gently, gave him a look, and lay in bed with a face of death. ...
A murder case occurred in the single dormitory building of the city electric wire factory. After receiving the alarm call, the police quickly rushed over. The deceased named Tian Chao, a technical backbone of the Municipal Meteorological Bureau, was strangled in bed. The callers were Jun Tang and Zhu Zizhen, who rented the same building.
There are signs of burglary in Tian Chao's home, especially in the drawer of the computer desk, and everything inside has been turned out. The footprints and fingerprints of the thief when he entered the house were extracted, and the thief who broke into the house was suspected of murder.
After investigating the scene, Xiao Fei, the captain of the criminal investigation team, reached out to open the computer of the deceased and found that it could not be turned on. After a brief thought, he immediately asked the technicians to unload the hard disk on the computer and take it back.
That night, a car accident happened on the road not far away, and the victim died. According to the driver's account and the on-site surveillance video, the victim rushed out of the roadside in a panic and wanted to cross the road. At this time, a truck was speeding along the deserted highway. The driver didn't expect someone to cross the road quickly in front, and there was no time to brake. The victim's body was thrown into the sky like a ball, and there was blood everywhere on the road.
Xiao Fei thinks the two murders should be related. He specially invited Jun Tang and Zhu Zizhen to identify the bodies of the car accident victims. As expected, the two men recognized this man as an escaped thief from his clothes and figure. Later, according to the local police station, the man was a habitual thief. The suspect's footprints and fingerprints extracted from Tian Chao's home are exactly the same as those of the car accident victim. The murder suspect is dead, so the case should be closed. Who knows, then something strange happened.
Back at the station, Xiao Fei connected the computer hard disk unloaded from Tian to his laptop. He found nothing on the hard disk. An hour later, his laptop was infected with a virus.
After the operation of computer technicians, the virus was eliminated. Technicians told Xiao Fei that this virus is a sophisticated Trojan horse program, specifically for the weather forecast system, tampering with meteorological data. This virus is only effective in a specific system environment. If other systems are infected, the computer will not start. At present, meteorological data are automatically collected and analyzed by computers. This virus will adjust the data in the weather forecast system to predict light rain as moderate rain and moderate rain as heavy rain. ...
Xiao Fei was surprised. It is not difficult to design a hacker Trojan and tamper with meteorological data. The question is, who can benefit from tampering with meteorological data? Why does a technical backbone of the Meteorological Bureau do this?
In the afternoon, the vice captain of the criminal investigation team came back from the Meteorological Bureau. According to his investigation, Tian Chao was assigned to work in the Meteorological Bureau from other places last year, and the housing in the bureau was tight, so he was subsidized to rent a house in the city wire factory. He works hard, treats people sincerely, has no girlfriend, likes reading books and stock trading, and has not had any work or economic problems so far.
Xiao Fei mused, "He studied meteorology, not computer, so the Trojan horse program in his computer must have been developed by someone else. In this case, there should be a USB flash drive, so where is this USB flash drive now? "
In the evening, Xiaofei is on duty at the station. He picked up the interrogation record during the day and read it carefully. Suddenly, his eyes were fixed on a sentence that Jun Tang said in the transcript: "When we chased him, he disappeared outside the gate in just a few seconds ..."
It disappeared in a few seconds. How did this happen? Xiao Fei frowned.
Half an hour later, Xiao Fei appeared again in the city electric wire factory. He and Jun Tang stood in the empty apartment downstairs in the dormitory, listening to Jun Tang's story of chasing thieves in the morning and looking at the gate. Suddenly, a shadow flashed through the gate, and Jun Tang exclaimed, "This is the shadow I saw last night." Phillips saw it, too, and said in surprise, "That's from the headlights on the road!"
There are some trees outside the gate. When the lights on the road are on, the light source moves and the shadow moves in the opposite direction. This simple principle actually caused Jun Tang's illusion.
"It's headlights! I thought it was a figure, but it was actually a tree shadow. I was cheated! " Jun Tang said gloomily.
Xiao Fei thought nervously and said, "When you saw the moving shadow of the gate disappear, you mistook it for a figure. But what would happen if you ran down a few seconds earlier? "
Jun Tang thought for a moment and said, "If I had run down a few seconds earlier, I wouldn't have been cheated, and I would have seen the thief."
Xiao Fei said: "That's right. Zhu Zizhen ran downstairs before you. He must not have been deceived by the shadows. He should have seen the thief, but he pointed to the moving shadow of the gate and told you the direction in which the thief fled. This shows that Zhu Xi is really leading you to be fooled and deliberately letting the thief get away. "
Zhu Zizhen's suspicions have increased. After investigation, Zhu Zizhen has been speculating in futures and bought a lot of soybeans in his futures account. The day of clearing the field was actually the day when Tian Chao was killed. He made a lot of money.
"I see, the virus in Tian Chao's computer was developed by Zhu Zizhen." Xiao Fei said to the police, "I thought about it. Who can benefit from tampering with meteorological data? Now I understand that Zhu Zizhen's speculation on futures is also speculation on the weather. Think about it, soybeans are a specialty of our city. If the weather forecast at this time says that there is a meteorological disaster in our city, then soybean production will definitely decrease. Once futures speculators know, soybean futures prices will soar. If someone buys a lot of soybeans at a low price in advance, they will become rich overnight. At that time, there was glutinous rice in Jiangnan and rubber precedent in Hainan. "
After the trial, Zhu Zizhen confessed that after he and Tian Chao became next-door neighbors, he learned that he was a technician of the Meteorological Bureau and liked to speculate in stocks. First, add the other person as a QQ friend and constantly instill in him the benefits of speculating futures on QQ. When the time was ripe, he handed Tian Chao a USB flash drive and put forward the dividend conditions. There is a Trojan horse file in the USB flash drive, which contains a tutorial. Tian Chao read it only once. He accepted Zhu Zizhen's terms, connected Trojan files to the intranet, and infected the server. From that day on, the computer analysis system of the Meteorological Bureau began to appear deviation. The weather forecast itself is uncertain, so it is obviously a rainstorm, and people will not notice why there is no rain in the sky
Until Zhu Xi really thought it was time to clear the stock and get the USB flash drive back. So that night, he knocked on Tian Chao's door and strangled Tian Chao. Then, he dug out the USB flash drive from the computer desk. When he left, he erased his fingerprints and footprints, deliberately put an iron drum in the middle of the room, then opened the door and slipped back to his room. He knows that the back door of the wire factory is wide open day and night, and thieves often patronize it. He wants the thief to enter Tian Chao's room, so that the thief will become a murderer.
Sure enough, a habitual thief appeared. As soon as he entered the door, he knocked down the iron drum in the room and gave a "dong" sound. Zhu Zizhen, who had been eavesdropping in the next room, rushed out at once and shouted to catch the thief, hoping to scare the thief away. Unexpectedly, Jun Tang quickly ran down from the fourth floor. Zhu Xi really knows that thieves can't be caught. To drive away the thief is to drive away the murderer. As long as the police lock the absconding thief as the murderer of Tian Chao, they will be safe. At that time, the thief hid under the stairs. He saw it at a glance, but he deliberately let Jun Tang run outside the door so that the thief could escape. Jun Tang mistook the moving shadow outside the gate for a figure, which helped him a lot.
After closing the case, Jun Tang inexplicably asked Xiao Fei: "Why did Zhu Zizhen kill Tian Chao?" Xiao Fei said: "He and Tian Chaoda have become mutually beneficial conditions. It is illegal to manipulate futures trading in disguise for his own profit, so he killed someone. "
