Evidence hunting forensic 4 unsolved case code

After lunch, Lin Dong convened a meeting with members of the serious case team of the unsolved case team and leaders of various departments to report on the progress of the investigation and seek opinions.When there are too many people in the meeting, the meeting room will inevitably be filled with smoke. Non-smokers try to sit by the window as much as possible.It was drizzling outside, and the sliding windows were wide open. When people came in and out, the air was convected, and the cold wind mixed with humidity was blowing in, blowing away a little smoke.In the past few years, the smoke alarm in this house was smoked once, which triggered the automatic fire extinguishing device and soaked the water all over the white shirts present.But no one has a long memory, whether it is time to smoke or smoke, but the alarm is wrapped up by someone with a tape.

After hearing the briefing and reviewing the compiled investigation report, Chen Fei, the person in charge of the serious case, said: "This case has been dragging on for a while, and now that Team Lin and the others have an idea, let's continue to pursue it, that Ronaldinho, today you sort out all the materials of the case at hand, and hand it over to Miao Hong and Yuan Qiao to go through the process, and you lead Ou Jian and the unsolved case to pursue Chen Jun's case, and we will try to solve it a year ago."

When Luo Jianan heard this, his eyebrows tended to droop slightly.It was obvious that Fade Chen asked him to serve as Lin Dong's maid, but the case was left unsolved in his hands, and it was also true for the dwarves.Having said that, how many serious cases are piled up in a day?If you give him enough effort, he can work hard on a case like Lin Dong, and he can't fail to solve it.While people were researching and replying to the post in the office, he and the outside were busy identifying people at the scene, visiting the victim's home, and taking statements at the hospital.

Feeling uncomfortable in the heart is the feeling of being uncomfortable in the heart, but on the surface it is okay, he can only forcefully answer the boss's order with the corner of his mouth raised.Ou Jian, who was sitting behind him, was very active. He sniffed and was blown out by the cold wind, and said happily: "Got it! Team Chen! We promise to complete the task!"

For Ou Jian, it doesn't matter if he can be a servant girl to anyone, as long as he doesn't throw him in a mental hospital for another month.It was Luo Jianan who forgot about his work before, and there was no mobile phone in there, so the child almost drove him crazy.But he has also seen all kinds of things in the world, and has a deep understanding of the ups and downs of mentally ill patients. At least from his point of view, those people are cute when they are not ill.Many of them have high education and high IQ. There is a professor of mechanical engineering in the room with him. His biggest hobby is designing "Noah's Ark". The parts are drawn more delicately than those modeled by 3DMAX.

The direction of screening replies proposed by Lin Dong was unanimously approved.After discussions among the people, the key words were locked on related words such as "interrogation", "truth serum", "tell the truth" and "confess the truth".Since Ou Jian has a background in communications, Lin Dong threw him to work with Yang Kelin on information investigation.Yue Lin can't use it for the time being. He just called his family and heard from his father that the child had a fever of 39°C and was going to be sent to the hospital for IV drip.

After screening, many people have the knowledge that LSD can be used as a means of interrogation, although this statement has not been officially certified.The selected replies are still massive, and it is difficult to compress the scope further down, so Lin Dong applied for a confirmation letter and asked Yang Kelin and Ou Jian to contact the platform to provide the selected user registration information, with the provincial salary Lord, a second round of screening will be conducted.

Tang Zhexue believes that the scope can be further reduced to the scope of this city.From the analysis of the suspect's behavior, this person is not only familiar with the inside of the hospital, but also the surrounding areas, so he should be from the city.But Lin Dong's consideration is that the patients admitted to the mental hospital are not limited to the city's household registration population. Many of them come from other places, as do their family members.

This link is more time-consuming. Some platforms must register and log in to leave a message. Users of this type can obtain relevant information such as mobile phone number, ** number, WeChat or Weibo number through the platform, and then bind with the patient through the real-name system. Family information cross comparison.However, on some platforms, visitors can speak without registration. For such users, the platform can only provide the IP address when they post.And IP addresses can be found everywhere, including many overseas IPs. Even if the user is in China, they can jump in multiple directions through the proxy server and cannot be traced.

Three days have passed, and the cross-comparison of the real-name system information is fruitless.Realizing that this road will not work, Lin Dong fell into deep thought again.Technological means can help the police locate the target in the vast crowd, but the Internet is too illusory, so we still have to start from the most fundamental point—the motive of the criminal suspect.

What's so good about interrogating Chen Jun?Apart from the Sunflower case, there seems to be no other solution.The woman went to see Chen Jun wearing a sunflower-patterned dress, fed him hallucinogenic drugs, and all of the above, it looked like...

"Reconstruction of the scene?" Luo Jianan's mind was finally free to study the case. In the past few days, he has made up the files of the Sunflower case. ? Use some special items that can evoke the memory of the witness, give some hints to guide the thinking, or take them to the scene of the crime, so that the questions you ask are basically eight or nine times the real situation."

In the unsolved case team office, everyone looked at each other and agreed with Luo Jianan's opinion.

"So, the suspect is not necessarily a family member of a patient in a mental hospital, but a person related to the Sunflower case." Lin Dong said, frowning slightly, "Xiao Luo, you have checked Jin Wanwan's family, right?"

Luo Jianan immediately said: "Then it must be her family members who came to investigate, parents, sister, and no time to commit the crime. Team Lin, I am not an afterthought. In fact, we also thought about investigating the family members of the patients in the mental hospital at that time. But the scope is too large, and Ou Jian didn't find out for a month."

Ou Jian on the side turned his head, and silently rolled his eyes, "I'm to blame?", and asked Wen Yingjie to look straight at him.Wen Yingjie stretched out his arm and patted his leg to show comfort.

"Could it be someone who was implicated in this case?" Tang Zhexue put forward an idea, turned back and took out the workbook of his father from the drawer, and opened it, "It is written in my father's work log that in order to check Jin Wanwan In this case, the task force interviewed thousands of people, and the number of interrogators exceeded 24... At that time, it was not as disciplined as it is now. They had to be released after being interrogated for more than [-] hours. Some people left for several days without notifying their families. , the impact on the reputation of the person being interrogated is often great, so...maybe someone has a grudge because of this?"

"How did the suspect know that Chen Jun was involved in the case? When Chen Jun was tracked down, we did not release any media information. Even now, the three people involved in the case, Chen Jun, Sun Yongping, and Su He, have all died. Didn't release even a little bit of news to any media, could it be..." Lin Dong said, looking around the entire office, scanning everyone's face one by one, "The news leaked from one of us? "

"..."

Everyone looked at each other with doubts in their eyes.I don't know who cast their eyes on Wen Yingjie first, and after a while, everyone stared at him.Only his family has a media person present here, and his stepmother Qiu Ying tried to get in the way of the "Innocence Paradise" case before, and the news leaked from him. It can be said that there is a lesson from the past.

Realizing that everyone suspected him, Wen Yingjie's expression froze, and he immediately raised his hand to swear: "I never brought any information about the Sunflower case home, I swear."

"Yes, Yingjie won't be so careless." He Lan spoke up to support him.Although she also doubted for a moment, she was willing to believe that, with Wen Yingjie's personality, at least he would not deliberately leak case information to Qiu Ying.

In the silence, Yang Kelin stretched out his hand to Wen Yingjie.

Wen Yingjie was taken aback, and subconsciously rubbed his chair back: "What are you doing?"

"Give me the phone," Yang Kelin asked calmly, "I'll see if I have the virus."

This request made Wen Yingjie feel a little unhappy, and his tone suddenly became a little displeased: "How is it possible, I never install software that is not on the green list. Checking mine is worse than checking yours. You play games and go online every day."

Yang Kelin didn't speak, but still stretched out his hand stubbornly.From Wen Yingjie's point of view, this move was aimed at him.The reason is simple, Yang Kelin likes Rong Sen, and Rong Sen treats him well. Although there is no established relationship, he is still a nominal rival in love.

During the stalemate, Lin Dong took out his mobile phone and handed it to Yang Kelin, and gave an order in the tone of a leader: "Everyone give Yang Zi their mobile phones and check everything."

The results of the inspection were unexpected. Except for Yang Kelin's mobile phone, all the mobile phones of the unsolved case team were spared, and all suspicious processes were detected.After a brief shock, Lin Dong called Hou Chu from the technical department and told the truth about the situation.This is considered a network security incident. If the higher-ups really want to investigate it, the technical department will have to follow suit.

After receiving the news, Hou Chu also expressed his shock, after all, it was the first time he encountered so many cases of poisoning of police officers' mobile phones.After carefully studying the process code, he made a professional judgment: this is an embedded virus, and according to the system log, it had been implanted into their mobile phone a few months ago.

Tang Zhexue instantly recalled the matter of his previous phone calls, and said in surprise: "When I asked Yunfei to check the phone, there was no warning of poisoning!"

"Didn't you just run the anti-virus software at that time? The anti-virus software can't recognize this virus at all!" Hou Chu's eyebrows were frowned, and his eyes never left the program analyzed on the screen. "The person who wrote this virus is a master, Yangzi, Take a look at this embedded camouflage method..."

In terms of technology, Tang Zhexue listened to the conversation between Hou Chu and Yang Kelin. Lin Dong had worked in Internet security, so he understood a little bit. The more he listened, the more he frowned.As Hou Chu said, the virus writer is a master.Embedded virus is very difficult to write. It needs to embed the virus into a specific program, pretend to be a part of the program, and run as a non-core thread of a process after startup. It is extremely concealed and difficult to be found and terminated.The reason why Yang Kelin's mobile phone is able to survive alone is because it has an anti-virus program written by himself, which can prevent viruses from modifying the startup items of the registry.

Closing his eyes and taking a heavy breath, Lin Dong opened his eyes, facing Luo Jianan's serious gaze.From the gaze of the other party, he deciphered a chilling fact——

This person is here for you.
