Evidence hunting forensic 4 unsolved case code

Sometimes things can't help talking.At noon, Tang Zhexuecai and Luo Jianan chatted about their student days, and in the afternoon, a friend who slept with him at the university called, and asked him to attend a class reunion during the Chinese New Year, tentatively scheduled for the sixth day of the year.Let alone the sixth day of junior high school, whether Tang Zhexue will have time to rest next Saturday is open to question, so he can only give the other party a reply of "count me in first, and see if we can see the situation".

"Hey, you said that those of you who entered the system are too uncertain." The other side complained, "I made ten calls, but nine of them couldn't be settled."

"Who is so free?"

Tang Zhexue was more curious about which one was settled.It stands to reason that the busier the police are during the holidays, especially those from their public security department, most of them fall into the police station, the legal department or the publicity department.It's better for someone like him to be transferred to criminal investigation. The number of criminal cases was high in the past year, and criminals can be more or less calmed down during the Chinese New Year.

"Ju Ling, she works from nine to five."

Hearing the name on the phone, a clear image of a beautiful woman flashed in Tang Zhexue's mind.Ju Ling is the flower of their class, she is naturally beautiful and looks sweet, but she is not a fool who relies on her face for food.Ju Ling got good grades in school, but she was admitted to graduate school and went to the court after graduation.When mentioning Ju Ling, he thought of Tao Zhihui again, because Ju Ling's postgraduate quota originally belonged to Tao Zhihui.At that time, there were rumors that Tao Zhihui's expulsion was actually related to Ju Ling's father. Her father was the director of the school's Disciplinary Committee Office, and he was in charge of the rewards, punishments, honors and disgraces of the police officers.

But rumors are rumors after all. From what Tang Zhexue saw, Ju Ling liked Tao Zhihui. A man deserves a woman. She is unlikely to give her father the opportunity to squeeze Tao Zhihui away.It was impossible to pierce the window paper because Tao Zhihui had a girlfriend at that time, and he was very affectionate, so affectionate that he would rather not have a future but stand up for his girlfriend.What's more, he committed a serious crime, and he was lucky not to go to jail. Whether to fire him is actually not something that Director Ju can decide alone.On the day Tao Zhihui was sent away from school, Tang Zhexue saw that Ju Ling's eyes were swollen like peaches, and felt that she must have cried all night.

Reminiscing about the past before the party started, Jiyou heard Tang Zhexue mention the squad leader, and sighed: "Yes, it's a pity for Lao Tao. With his ability, he will definitely stay in the department, and he also said that he can hug the department in the future. Where's Daddy's thigh?"

Tang Zhexue was dumbfounded. If he wanted to talk about hugging his father's thick legs in the department, their unsolved case team would do his part.But those are all Lin Dong's contacts, and he hasn't been formally received by ministerial leaders yet.As the saying goes, "If you are poor, no one cares about you in the busy city, and if you are rich, you have distant relatives." When Lin Dong was in distress before, everyone in the phone address book seemed to be dead. Later, when he made a comeback, those people cheated on the corpse again.

After chatting a few words, Tang Zhexue hung up the phone and continued to study the transcript of the testimony.Next to him, Luo Jianan kept talking, chewing beef jerky and complaining about logistics. Jia Yingchun chicken thief: Beef jerky sold for 19 yuan in the supermarket changed to 25 yuan in the cafeteria. If it wasn’t for lunch, it would be impossible Give Lao Jia a chance to earn his hard-earned money.

——Is that your hard-earned money?It's obviously my fault.

Tang Zhexue silently swallowed his grievances.I don't know if it was during the meal, but Luo Jianan's mouth was all used to coax Qiming to eat. When he and Lin Dong went to the cafeteria to swipe their card to buy food, this buddy came over, took his card and swiped it twice. Bag of beef jerky.However, no matter how bandit Luo Jianan was in the past, he would never steal from his colleagues. He thought that probably Luo Jianan’s meal card had been placed there by Qi Ming, and Qi Ming restricted him from eating food with too many industrial additives because of Luo Jianan’s poor stomach. Just swipe his card.Besides, Lin Yang also kept Luo Jianan in the ICU for half a month, and he had to pay the debt owed by his relatives himself.

A bag of beef jerky was eaten with hot tea, Luo Jianan patted his stomach contentedly, and turned his head to Yang Kelin who was nesting in the corner of the office and raised his chin: "Hey, Yangzi, how did you catch up with your IP address, did you get any results?" ?”

"Not so fast. The system log shows that the other party keeps changing the cloud server to attack my host. These are public IPs, which are invalid. I want to block them one by one." face, and Luo Jianan who had a face of "What did you say?"After thinking for a while, he added an explanation: "The other party sent the water from the reservoir to rush at me. I can't pinpoint which river the attack came from. What I'm doing now is to force the other party into the water storage with only one exit. Pool."

"Oh……"

Luo Jianan probably understood, and you can ask Ou Jian about the specific technical operations later. Right now, there are too many people in the office of the unsolved case team, so it's hard to be too ignorant.I didn't know that Ou Jian knew programs before, but I only knew that the other party's university major was related to computers, so he could put it in the office as a network administrator.That day, the computer crashed, and he called Ou Jian to come over to fix it. He saw that he opened the DOS command window for a while, and when he opened the internal system page, it was as smooth as Dove, and then he suddenly realized that his third child still had a bright spot. of.

Very good, he thinks, cyber crimes are becoming more and more rampant, mastering computer information technology, in the future, for police students, it may become as important as obtaining a driver's license for graduation, as many jobs now require a computer grade test when recruiting Certificate.Because of this, he came up with the idea of ​​learning a programming language, and asked Ou Jian to find a few books, thinking that he would look through them in his free time, even if he had a shallow impression in his mind, so as to save the trouble of meeting when cyber crimes were involved. Time is like listening to the bible.However, it turns out that he is not the material to learn that. Reading computer program textbooks is more hypnotic than reading Qi Ming's forensic professional books.At least he could read a dozen or so pages of Qi Ming's book and take notes, but Ou Jian gave it to him, and he fell into a deep sleep within three pages, and he didn't know where to throw the pen when he woke up.

It is true that there are specializations in the art industry. After all, not all crimes are committed on the Internet. It was not in the past, and there will be no less in the future.It is enough that someone can use the technology. He has worked in criminal investigation for more than ten years, and it is unrealistic for him to go to the dissection room to compete with Gao Ren for a job.Those who do criminal investigation, especially the older generation of investigators, are miscellaneous and know everything, but except for those who are really interested and can devote themselves to a certain professional field, most of them still rely on experience and meticulousness Observation to solve cases.

Everyone in the room was busy with their own activities when Lin Dong's cell phone rang suddenly. After answering the call, his expression was obviously serious, and he left the office in a hurry.Tang Zhexue wanted to catch up and ask, but seeing Lin Dong's performance, there must be something urgent, so it's inconvenient to disturb him at this time.After waiting patiently for more than half an hour, Lin Dong came back and put a printed document on his desk.

Standing beside Tang Zhexue's desk, Lin Dong rapped on the table with his fingers: "This is the email Qiu Ying received, about the Sunflower case, please take a look."

Everyone left their seats and gathered around Tang Zhexue to look at the copy.It was an email sent to Qiu Ying's work mailbox. A section of the report was copied earlier. The focus was on the last sentence, which was marked by Sheng Guilan with a red marker—"If the police are as conscientious as you boast , then where did our tragedy come from?".

Luo Jianan watched the lawsuit all over his head: "Us? Who are you? Where did this email come from?"

After glancing at the incoming and outgoing messages, Ou Jian immediately answered, "It's Yahoo Mail. The domestic server has been shut down since 2013, but the overseas server is still in operation, and you can log in through a proxy."

Luo Jianan frowned: "So you can't track down the IP?"

Ou Jian nodded.He has never used Yahoo mail, except for the mailbox of the work unit, there is only one Penguin mailbox that is commonly used.

Luo Jianan asked again: "Could it be the same person who sent the email and planted a virus on your mobile phone?"

He looked at Lin Dong, and Lin Dong also looked at him, seeing the same doubts in each other's eyes.If it was really done by the same person, it means that Lin Dong's method has worked. The report praising the police for their perseverance in solving unsolved cases successfully angered the suspect.

"Team leader, look at the sender's username." Tang Zhexue ordered some copy paper, "Hamlet0812, is it... Hamlet?"

Lin Dong noticed this point when he got the copy. "Hamlet", Shakespeare's masterpiece, also translated "The Prince's Revenge", was one of the English version books that he had to read when he was in school.After reading the whole article, he has a great feeling about the change of thought of the character Hamlet before and after.So from his point of view, the sender's use of this name to register an email address may mean that the other party is a person who has suffered injustice and has disillusioned his ideals, and has a deep-rooted obsession with "revenge".

So what does 0812 mean?Is it a random string of meaningless numbers, or...

"Will it be a birthday?"

Hearing Lin Dong's question, Luo Jianan immediately put forward his own opinion.He has the habit of adding his birthday 0614 to the end when he encounters a duplicate user name when registering an online account.Now it has been changed to Qi Ming’s birthday, 0218.It's not considered flattering to his wife, it's because he always forgets his birthday, but he can't forget his daughter-in-law's death.

To make a digression, Cao Yuan has a heart-warming act of recording the birthday of her colleagues and sending them blessings on their birthdays.When asked about Qi Ming's birthday, he said that Luo Jianan and Qi Ming are twins with water bottles, and their compatibility reached 100%.At that time, Cao Yuan saw that he was so beautiful that snot bubbles were about to pop out of his virtue, so she silently swallowed the second part of the sentence "Just don't quarrel, you can blow up the earth".

"Xiao Luo is right, it really looks like a birthday date," Lin Dong nodded to confirm, "Ou Jian, please do a cross-comparison of the personnel information we collected earlier to see if anyone has a birthday on August [-]th. Erji, when you go through the interrogator's information, also pay attention to the ID number to see if anyone has a birthday on this day."

When the leader spoke, everyone returned to their positions immediately.Lin Dong sat back at his desk and swiped his mouse to wake up the dormant computer.In less than 5 minutes, Ou Jian reported the result of the inquiry: "Team Lin, there is no birthday on this date in the patient's family."

Before Lin Dong could speak, Luo Jianan looked disgusted: "Then I don't know if there are any patients? Why do you have a long brain?"

Ou Jian put on an aggrieved face in an instant.Love is not good love, it is about people like Luo Jianan who are very protective when they go out, and it is easy not to give him good face in private.Having said that, even if he didn't think thoroughly enough, wouldn't it be okay to go back to the Serious Cases Office and close the door to scold him? If he had to scold people in the Unsolved Cases Office, wouldn't he lose face?

The eyes went back and forth between the two seniors, and Dong Dong, the leader of Lin's family, decided to help Ou Jian find a step down: "I didn't make it clear, Xiao Ou, please, and screen the patient's information."

Ou Jian immediately came to life: "It's sifting, right now, Team Lin!"

Before the voice finished speaking, the search results were highlighted by the cursor, and there really was one.

"I found Team Lin, called Zhou... Hey, Sister Lan Lan, what do you think this word reads?" Ou Jian knocked when he encountered an uncommon word suddenly, and turned the computer screen towards He Lan.He has a master's degree in law, and he must be better in liberal arts.

He Lan leaned forward to have a look, and said, "Recite Yao, twice."

Weekly?Tang Zhexue raised his head when he heard the words—why does this name sound so familiar?
