In fact, when Feng Yan and they found out that Cheng Fei was in high school, Xu Jiayan would most likely kneel, as long as she checked Gu Yao's identity information and found her ID card information (the resident ID number is unchanged for life), it would take a little time to know that she had changed her name.

However, without Feng Yan's 10-point analysis and accurate finding of the second devil, getting his testimony, and knowing that Cheng Fei is gay, the police would not have thought of investigating Gu Yao at all.

I have to say that at that time, Feng Yan suggested to investigate the situation of Cheng Fei in high school, and he must find the second devil of the year, which is really wise to the point, and this has also become the key to solving the case.

As a result, Wu Yu began to investigate according to Feng Yan's prompts, aren't you Gu Yao clever and choose to evaporate from the world after graduating from high school? I don't need to check you Gu Yao now, and I don't have that time, I just need to check Xu Jiayan.

started doxxing through Xu Jiayan's ID number, and found that she had changed her name, she was called Gu Yao before, and through this identity information, she found out that she had been in Beijing for many years, and she had plastic surgery, and the photos before plastic surgery were compared with high school, and they were the same person, who were Cheng Fei and Zhou Yang's classmates.

Xu Jiayan joined a media company while in Beijing, and when she contacted the media company, her former colleague provided the reason why she had been unpopular and the situation during her employment, and a gossip female colleague provided information that she was unwilling to uncover the rules. also found the train entry record of her return to Yunhai City 1 year ago.

The identities of Gu Yao and Xu Jiayan overlapped, and after the investigation of Qian Yiyun reached a conclusion, it was explained why Xu Jiayan wanted to play Qian Yiyun and the police. It was a trick, not a retaliation.

The first is because Xu Jiayan is not so capable.

The second is that although her uncle and aunt raised her since she was a child, she has feelings, but she has not reached the level of helping them retaliate against Qian Yiyun and the police, which can be seen from the fact that she stopped contacting her aunt not long after she graduated, and she didn't take her aunt's feelings seriously at all.

The third is because Qian Yiyun didn't kill her uncle, but just treacherously refused to compensate through the contract loophole, strictly speaking, it was true that her uncle didn't see the contract clearly at that time, which is an act without business ethics. It can be said that Qian Yiyun is not a thing, and it can also be said that Yiyun Insurance is an unscrupulous company, but people did not do anything illegal, on the contrary, Qian Yiyun still won the lawsuit through legitimate legal means. There is nothing wrong with the police's approach, you lost the lawsuit and ran to other people's homes to make trouble, so it's not too much to arrest you, right? In order to protect the safety of citizens in the later stage, it is also possible to monitor you.

Let's say there is no emotion, there must be some, so Xu Jiayan decided to be disgusting and disgusting before killing Zhou Yang, Yi Yun Insurance and the police, on the one hand, she avenged the revenge of the year, and on the other hand, it was also her real purpose to satisfy her fanatical conceit.

Then the police found out that two months ago, that is, when Xu Jiayan and Zhou Yang were together for three months, she drove to Shanghai, and then frequently went in and out of Shanghai and Yunhai, how to determine her license plate number? That's interesting, Wu Yu really listened to Fengyan's first point of advice, and went to check the records of Yunhai and Wanning Expressway in recent months, through big data comparison, there is a license plate in a certain week, frequent round-trip between Yunhai and Wanning, this week, the car with this license plate went back and forth 7 times, that is, 14 one-way trips.

Do? What about playing? Take advantage of the fact that the oil price is about to rise, hurry up and refuel the oil?

checked the license plate and found that the owner was Xu Jiayan, and she didn't fake the owner's information, and she couldn't think of it.

As mentioned above, once Feng Yan's method of trying to find the suspect vehicle is located, through the owner of the car, the murderer can almost be locked, is it so coincidental? You, a Xu Jiayan related to the case, like to drive back and forth on the highway so coincidentally?

Xu Jiayan didn't expect that someone would check this kind of record at all.

After locking Xu Jiayan's license plate, the rest of the matter is much simpler and faster. Through the records of entering and exiting the expressway, as well as the entry and exit records of various parking lots, communities, shopping malls, and hospitals, it was found that Xu Jiayan often went to Fan Qihao's community during this period, and the monitoring of the community was retrieved, and the picture of the two entering and exiting together was also adjusted, and it can be basically determined that Fan Qihao's girlfriend is Xu Jiayan.

But the basic certainty is basically certain, if there is no witness, this can only be speculation, and Fan Qihao must admit that Xu Jiayan is his girlfriend before this matter can be determined. But Fan Qihao just doesn't spit out, what should I do?

The police found the picture of the pregnancy test form in Fan Qihao's mobile phone, and after a little identification, it came to the fact that this was a fake pregnancy test form, as expected, Xu Jiayan and Fan Qihao's WeChat and mobile phone numbers chatted were all registered with fake ID cards, and her name to Fan Qihao was fake, so naturally it was impossible to determine that the person in Fan Qihao's mobile phone was the same person as Xu Jiayan.

But when the police told the situation of this fake pregnancy test sheet and the general situation of Xu Jiayan's murder, Fan Qihao went to the bottom of it, and as soon as the photos were compared, it was immediately determined that Xu Jiayan was his girlfriend, and he was not a fool, this is a murder charge, before he thought that Xu Jiayan was pregnant, and thought that he would take the blame and let Xu Jiayan and the child live.

The situation is like this, when Xu Jiayan separated from Fan Qihao for the last time, she told him that she was going to do a big thing, and asked Fan Qihao if someone bullied her, would he help her, of course Fan Qihao had nothing to say.

Later, when the police found Fan Qihao, remembering the last face-to-face conversation, Fan Qihao immediately became vigilant in his heart. The Shanghai police didn't get the evidence of the lullaby at first, but only asked him about the relationship with Cheng Fei and other topics, Fan Qihao was very strange, but he told the truth about his relationship with Cheng Fei, and after he went back, he contacted his classmates in Yunhai City, only to learn that Cheng Fei's husband Zhou Yang died in a car accident, and the cause of death was fatigue driving.

He immediately contacted Xu Jiayan, Xu Jiayan cried that she put Fan Qihao's lullaby into Zhou Yang's car, making him doze off and fall into the river, Xu Jiayan said that Zhou Yang had killed her before, and she was taking revenge.

When Fan Qihao was summoned for the second time, he had already come to his senses, but he still wanted to resist, but when the police released the song, he knew that everything was useless, so he decided to help Xu Jiayan carry all the guilt.

This is also the reason why Fan Qihao probably knew the process of killing, but he didn't know the details as well as Cheng Fei, because Xu Jiayan didn't tell him the details, and it was impossible to tell him.

Later, after the police learned that this was a fake pregnancy test report, they used this as a breakthrough and told Xu Jiayan all the things that were interspersed between him, Zhou Yang and Cheng Fei, Fan Qihao felt that he was a stunned young man, and naturally he would not help Xu Jiayan to take the blame again, and tell the two of them about this time.
