Wang Wei, a technician from the Network Investigation Section of the Haigang City Police Department, is not only a computer expert, but also a rare talent in network investigation.

Internet investigation is essentially different from other criminal investigations in that it is based on the Internet.

Wang Wei is the technical director of the Network Investigation Section. The memory card storing the video found in Yaxin's head was processed by Wang Wei.

Wang Wei adjusted his black-rimmed glasses and had an elegant smile on his face. He was not very tall, his skin was a little fair, and he looked a little bit cowardly and kind. He didn't look like a cybercriminal investigator at all.

"Is the victim's phone unlocked?"

Liang Yi finally heard the best news. There was so much personal information in his cell phone that the victim's identity could almost be determined by restoring his cell phone.

Various bank mobile apps and other real-time social communication software have real-name authentication, which is very helpful in determining the identity of the victim.

The first step to determine the identity of the deceased is a crucial step and the beginning of the entire investigation. If the identity of the deceased cannot be determined, solving the case under such premise is like finding a needle in a haystack, which is almost impossible.

"I have some special discoveries. Captain Liang, please follow me to the Network Technology Department." There is a lot of content on the phone, and Wang Wei needs to analyze the specific situation in detail.

Liang Yi looked at Han Qi with gentle eyes and pointed to the food bag placed on the table in the office next door, "I bought you your favorite fried pork with bamboo shoots. Go eat first. People are like iron rice and steel.

If you are exhausted, I will have no confidence in solving the case."

"Thank you!" Han Qi also knew that Liang Yi was not good at expressing herself. She bought some rice for her, including her favorite stir-fried pork with bamboo shoots. It was obvious that she had a good attitude of admitting her mistake.

"Remember to eat! You are still a doctor. People will secrete some digestive juices during three meals. If you don't eat at that time, it will have a great impact on your organs." Liang Yi said calmly, "I will go to Wang Wei first.

, I’ll come over later, I have something else I want to tell you.”

Han Qi saw a flicker of emotion in Liang Yi's eyes. Liang Yi had something to say. It didn't seem like a business matter, but a personal matter.

Han Qi continued to lower her head and study the horrific corpse.

Wang Wei and Liang Yi walked out of the forensic studio one after another and walked towards Wang Wei's Network Technology Office on the fourth floor.

Wang Wei's work office is just like a hacker's office. Wang Wei is relatively young and sometimes sleeps in his office at the Haigang City Police Station.

What makes Liang Yi feel strange is that many IT technical files often don't have a lot of hair, but Wang Wei's hair is unusually lush.

"Did that phone belong to a boy or a girl?" Liang Yi guessed in his mind that it must belong to the girl. At the same time, Liang Yi was thinking about what Han Qi said. The phone was doused with gasoline and the fire burned so badly.

It is impossible for electronic products to survive in a fire.

Deliberately leaving the key evidence of a mobile phone is to induce and guide the police to solve the case step by step.

There may even be some key perjury that cannot be refuted and have a causal relationship. Under crucial circumstances, this kind of perjury is likely to become real evidence, just like the case of Qin Peng molesting Zhang Yaxin.

Apart from what Liang Yi saw with his own eyes, the most powerful evidence is Qin Peng's animalistic behavior lying on Zhang Yaxin's body. The most critical evidence is the fluid from Zhang Yaxin's private parts and the girl's private parts. That fluid has been identified and analyzed by the technical department.

, the DNA does belong to Qin Peng, this is almost a death certificate.

Liang Yi has found a key piece of evidence. Qin Peng suffered from very serious diabetes at that time, which caused great damage to his kidneys. Qin Peng took a lot of drugs. At that time, Qin Peng basically couldn't move.

The probability of a man who cannot be hardened to engage in such beastly behavior is very low. Besides Qin Peng's personality, it is really hard to imagine that Qin Peng could do such a thing.

But Qin Peng’s case has been decided!

Han Qi's words served as a reminder to Liang Yi.

In the death case of Zhang Yaxin, the death of Du Yan in Huaigang City, Haigang City, and the death of a man and a woman in the fire, the surviving mobile phone will be the most critical evidence, guiding the police to explore step by step.

Liang Yi had an intuition.

The real murderer must be squatting in a dark corner, with a ferocious smile on his face, looking at the police happily, tangled up in the ants on the hot pot, and finally the police were led by him.

"Captain Liang must have guessed it, it's a girl! And I also know this girl's identity and very detailed personal information about her family."

Wang Wei was very confident, his eyes shining with justice, "This time the murderer may have been careless and did not expect to leave his mobile phone at the scene of the crime. The name of the girl who died was Yang Yan, a senior student at Harbor University. From the mobile phone

Judging from the stored photos, I have a very good relationship with Lin Wei. It must have been a few months ago, I don’t remember the details clearly. I went to the hospital and had an abortion, and there is a list of his hospital bills in the photos on my mobile phone.”

Liang Yi's head roared.

This result was beyond Liang Yi's expectation. Under such circumstances, Professor Lin Wei of Harbor University was the key suspect.

"Is there anything else?"

Wang Wei pushed open the office door and closed it. He lowered his voice and said, "Yangyang's phone was seriously damaged. I replaced it with a touch capacitive screen and found a battery that matched the phone model. Through Yang Yan's phone

Through the browser browsing history, I got a very scary secret."

"Go on..." Liang Yi realized the seriousness of the problem.

"I went to the official website of Harbor University and conducted a search on the Student Affairs Office website. Yang Yan majored in electronic information engineering technology. Although she is a girl, she seems to be particularly talented in this area. Yang Yan's father is also a teacher."

"No need to foreshadow, let's get straight to the point! Is Yang Yan related to the two previous death cases?" Liang Yi made a guess. Han Qi's words were very forward-looking. He left this key evidence on his mobile phone.

, guiding the police step by step to solve the case.

Even if the police know.

This mobile phone is very likely to be left behind intentionally by the criminal. However, the evidence clues in the mobile phone have triggered other evidence that is directly or indirectly closely related to the case. The police must also investigate one by one. They cannot

Let no one go.

"Yang Yan completed a transaction with a person through offline communication chatting on the mobile browser, and purchased virtual currency online to avoid our detection. These are not the main points."

Wang Wei's eyes lit up, "Yang Yan, a senior female student at Ocean University, provided the time bomb Zhang Yaxin placed near her head on the board."

bomb?

Liang Yi didn't hear clearly, "You mean, the time bomb placed on Zhang Yaxin's head was made by Yang Yan?"

"This is almost certain. Their chat records are all in the browser cache. Yang Yan majored in electronic information technology. It is not difficult to make this time bomb! In the university laboratory, almost all the materials can be gathered together.

"

"If we can contact the party who gave Yang Yan the time bomb! Then we will basically find the murderer of Zhang Yaxin."

Yang Yan will be involved in Zhang Yaxin’s death case!

This is the information that Liang Yi and the Haigang City Criminal Investigation Team have been investigating for such a long time but failed to obtain.

This way.

Yang Yan and university professor Lin Wei were whispering at the Lotus Lake on the university campus, and there were some problems.

There are two truths that need to be investigated before Liang Yi.

The first truth is, Yang Yaner had an abortion a few months ago. Whose child was she pregnant with?

The second truth is, who is the person who bought the time bomb through the virtual currency transaction with Yang Yan?

Liang Yi thought that if a girl could completely accomplish something, she must have a helper, and it was most likely Lin Wei.

"Are there any other clues?" Yang Yi didn't expect to find out from the scene that this mobile phone could have so much valuable information. Even if this was "perjury" deliberately left by the murderer, Liang Yi must pursue it.

.

"There is another very important news! I investigated Yang Yan's call records in the past two days and found that she made more calls to Lin Wei. There is another person with an unfamiliar number, and the other person is someone you know."

Liang Yi frowned slightly, "Who is it?"
Chapter completed!
