Evidence hunting forensic 4 unsolved case code

In the office of the unsolved case team at midnight, only the computer screen in the corner was still emitting a faint light, softly covering the person lying on the table.The rapidly switching images on the screen suddenly stopped, and the machine made a crisp beep.Yang Kelin woke up suddenly, straightened up and calmed down, rubbed his eyes, picked up the water glass with his left hand, moved the mouse with his right hand, and dragged the personnel information compared with the sketch into the folder.

To compare the three portrait sketches of the two cases, one by one was too slow. He spent half a day writing a plug-in for the face recognition software so that the three pictures could run at the same time.But the load on the machine is a bit heavy, the CPU, memory and graphics card are not enough, and heat dissipation is also a problem.The machine he used was air-cooled, and he wanted to change to a water-cooled one, but there was no approval from the above.So sometimes even if he knows that it is an illegal operation, he is still willing to take the work home to do it. At least the two-way CPU, 12G independent display, 512GB memory and 6T solid-state hard drive fully water-cooled machine that he assembled at home can run. Much faster than the unit.

But the work that needs to be applied to the internal database cannot be taken home, and can only be done in the office.Sometimes when everyone else is away from work, he is alone in the office all day long, so he is happy and quiet.When running the database, he can let himself go and play games with his mobile phone.People often think that he is lying down to catch up on sleep, but in fact he is playing games with him with his head down, quietly and with a very weak sense of presence.Before Lin Dong found out that he was playing games with the mobile phone issued by his unit, he was severely criticized, because downloading green software that has not been certified by the system is likely to cause the mobile phone to be planted with viruses.

Regarding Lin Dong's criticism, Yang Kelin didn't take it seriously.He is somewhat conceited in this regard, at least none of the hackers he has contacted so far can cause viruses in his machine.Of course, there are people out there, especially in hacker circles.Those little-known masters will not easily let others discover their small actions. Even if they are discovered, they will have already retired.

But he had to listen to what the leader said. He deleted the game and tested all possible loopholes with the program he wrote to make sure nothing went wrong.Now he plays with his mobile phone, Yue Lin sees that he sometimes struggles to score, and asks him why he doesn't write a cheat, so as not to be abused.

Regarding this, Yang Kelin's attitude is: "If I don't even leave this fair opportunity to others, then what fun do I have in playing games?"

Yue Lin rolled his eyes when he heard this—chuck, pretending to be struck by lightning.

After a while, the machine beeped again, and Yang Kelin browsed through it roughly, and dragged and dropped the information into the folder.He is in charge of the technical part, and the work of analysis and judgment is done by others.Compared with the above images, he will conduct some preliminary screening to eliminate those who obviously do not meet the possibility of suspects, so as to reduce the workload of his colleagues.

Just as he left the mouse, the phone rang, and it was a call from Rong Sen.

"Ah, I'm working overtime tonight, please lock the hidden lock."

Yang Kelin knew what he was going to ask, so he answered it directly.Sure enough, it hung up without saying a word.Rong Sen's house was decorated by himself, which gave full play to the creativity of a UI designer.The furniture and interior decoration perfectly conform to the ergonomic design, the arrangement of daily necessities is very logical, and the household appliances are basically fully intelligent.Yang Kelin once watched him stand by the stove, from cleaning and preparing ingredients to serving dishes, he finished a spicy crayfish without moving one step at a time.The craftsmanship is not bad, at least much better than his.

At the same time, Rong Sen pays great attention to personal privacy. He never lets Yang Kelin enter his room, and he must lock the door and bedroom with built-in locks when he sleeps.This kind of built-in lock is custom-made and cannot be opened from the outside, so if Yang Kelin works overtime and returns home in the middle of the night, he has to be knocked out of bed to open the lock.After going back and forth several times, as long as he didn't come home after twelve o'clock, Rong Sen would have to make a phone call to ask him if he was still coming back, so that he could hold the door for him.

To be honest, he really likes this way of getting along between the landlord and the tenant. They don't interfere with each other, and the sense of distance is maintained very well.Although Rong Sen is not as socially awkward as him, he is also a dead house. Except for necessary purchases and things that must go out, he basically doesn't go out very much. The only outdoor activity is to visit his mother in the mental hospital.Sometimes he feels that he is lucky compared to Rong Sen, at least his parents are still alive and mentally healthy, and he keeps a distance because he doesn't want to disappoint them.But Rong Sen's loneliness is passive, his father died early, his mother became crazy and didn't even know her own children, and he didn't see any relatives, and he didn't seem to have any friends. It can be said that no one in this world would care about his life. good and bad.

Once, the door of Rong Sen's room was not closed tightly. He was in the living room, through the thin gap, looking at the profile of the computer screen shrouded in soft light, inexplicably feeling a little lonely for the other party.At that time, his thinking was that if one day he saved enough money to buy a good house and move out, who else would fill Rong Sen's life and give this lonely person a little warmth and care.

He picked up his phone and called Rong Sen back.I had nothing to talk about, so I asked about Yingjie below.As I was talking, I suddenly felt a little funny, but my colleague had to ask the landlord about his condition.A little earlier, Wen Yingjie sent him a message. He didn't mention his illness at all, but asked him to find time tomorrow to send his office laptop to the hospital. If you are not idle, you are idle.

"leukemia?"

If it hadn't been for what Rong Sen said, Yang Kelin wouldn't have known what kind of disease Wen Yingjie had. The last time he went to the hospital to see Wen Yingjie, he obviously lived in the internal medicine ward, but this time he went to the hematology department.

"You don't know?" Rong Sen sighed, "Then just keep pretending you don't know. He didn't tell me. I asked his father to find out."

This is depressing news, Yang Kelin suddenly felt like a stone was pressed on his back: "No wonder he always has a fever, and the nosebleeds can't be stopped."

"Well, fever is an abnormality of white blood cells, and blood flow is not just a problem of coagulation."

"I didn't realize that you know medicine." Yang Kelin suddenly realized that he had lived together for almost a year, but he knew very little about the landlord.

There was nothing there for a few seconds, and he said, "I don't understand, I just heard what the doctor said, well, I still have work to do, so I'll hang up first."

"Well, go to bed early after work."

After finishing speaking, Yang Kelin was taken aback.It seems that he hasn't said it for many years, or he has never said it.Perhaps it was because of the loneliness of the night, he felt that some things he would not say or do during the day filled the lonely air under the night.

However, the leader didn't make him lonely for too long. A few minutes after he hung up the phone, Tang Zhexue called and asked him to call the information of the immigration system immediately to check whether a Vietnamese named Ruan Wenxiong had left the country.Tang Zhexue and Luo Jianan followed the clues of the roses to search the hotel, one after another, and finally someone recognized the guy in the sketch, saying that he looked like a Vietnamese chef at their place, but he had left the job for several months.

After investigation, Ruan Wenxiong has no record of leaving the country in the near future. The record of entry was three years ago. He holds a work visa and his registered residence address is Room 1503, Building C, Jinquan Garden.After getting the address, Tang Zhexue and Luo Jianan immediately rushed to Jinquan Garden, gathered the property staff on duty in the middle of the night, and identified whether the occupant of Room 1503 was Ruan Wenxiong.

The person in the property looked at it for a long time, shook his head, and said that there were only three foreigners in the community, one black and two whites, and there was no other place in his impression.The main thing is that Ruan Wenxiong looks almost like a Chinese, and he can't tell he is a foreigner even if he is thrown into the crowd.Luo Jianan went downstairs to look again, and found that the windows of 1503 were all dark. He didn't know if he was asleep or no one was there at all.At such a time, it is inevitable to come to the door to startle the snake, if Ruan Wenxiong is really the murderer.But they couldn't waste their time, so the two of them decided to put on a classic scene - Luo Jianan pretended to be drunk and went to the wrong door to see if he could knock him out of the room.

In view of the fact that what he needs to face may be a professional killer, in order to avoid being detected by the other party, Luo Jianan went to a convenience store and bought a bottle of sorghum wine to rinse his mouth, so that his mouth would be full of alcohol when he spoke.After performing a full set of plays, he poured half a bottle on his clothes, and he could smell the alcohol on him five meters away.

Taking the elevator up to the fifteenth floor, Tang Zhexue went to guard at the entrance of the corridor. Luo Jianan's shoulders slumped, he shuffled while leaning on the wall, his face changed in a second, and he looked like a drunk.Acting like anything, this is his forte.When he reached the gate of 1503, he raised his fist and began to beat, howling while beating: "Open the door~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~… I'm back~~~~~~~~~"

Tang Zhexue stood at the exit of the safe passage and watched Luo Jianan act. He felt that if this guy really drank too much and went home to beat the door, and put aside Qi Ming's temper, he would definitely let him sleep in the corridor overnight.Or why sometimes Luo Jianan drank too much and ran to him and Lin Dong to rub the sofa?It must have been cruelly rejected, and I have a long memory.

As a result, I knocked on the door for more than ten minutes, but there was no movement inside.Are you not here?Tang Zhexue frowned in doubt.Or do you see it through the cat's eyes, but ignore it when you find that you have gone to the wrong door?Just as he was thinking about what method he could use to carry out the work, the elevator door swung open, and he immediately tensed up, and dodged to the side of the safe passage, and at the same time reached back to the side holster— —Because the murderer might be a professional killer, the first thing Lin Dong did when he returned to the bureau in the afternoon was to apply for two guns, one for each of them.

Luo Jianan's serious case is to carry a gun for a long time, but right now no matter who comes, he has to continue to pretend to be a drunkard, with his back to the elevator door, slamming the door like no one else is there.As the footsteps approached, a big hand suddenly patted his shoulder heavily, and at the same time came a stern question: "What are you doing? Why are you howling in the middle of the night? Do you know if you disturb the people? What about your ID card? Take it out! "

This sounded a little familiar, Luo Jianan's heart skipped a beat, thinking that the food was broken, what the hell... He squinted, turned around crookedly, and his vision was immediately filled by the navy uniform——Fuck !You guessed it right!It's the police at the police station!The law enforcement recorder takes a face shot!

His breath was filled with the smell of alcohol, and the tall policeman frowned, without giving the drunk man in front of him a chance to explain, he twisted Luo Jianan's arm with his backhand, escorted him to the elevator, and reprimanded him as he walked: " What time do you not sleep! What are you making trouble with here! Go! Go back to the institute with me to sober up!"

Fuck!Luo Jianan is considered a dumb eater of Coptis chinensis, he can't tell the pain.I don't know which "enthusiastic masses" called the police, and the police station came to arrest him.The other party hit very hard, and his arm hurt a lot from being broken by him. However, if there is anyone in the room who doesn't know, it is impossible for him to show his identity in the corridor.

This is called flooding the Dragon King Temple, and my own family does not recognize my own family.

Tang Zhexue couldn't come out, so he could only stay where he was and listen to Luo Jianan being taken into the elevator by the police.After waiting for a while, seeing that there was no movement at 1503, he turned around and went down the stairs to find Luo Jianan along the safe passage.

All the sensor lights in the stairwell were turned off, and everything returned to calm. A few minutes later, the door of 1503 was opened quietly.In the silent darkness, a pair of black and white eyes scanned everything around vigilantly.
