Li Zhudao continued: "Between having a relationship with Zhang Jing or having a relationship with Wen Tao and others, the reason why Wang Kang chose the latter should not be out of protection for Zhang Jing, but because he had lost his male function at that time, and it was very likely that he had developed a hatred for women. ”

The mobile phone and number that Gui Ying assigned to Li Mei seem to have become a special plane for communication between her and the welfare home. Through a query of its records, it was found that most of the callers were leaders and staff members of the Yancheng Welfare Institute, or some children who had left the welfare home.

There are not many callers, but after a year or so, there are a lot of call records. When checking all the call logs and callers, it was found that one of the phone numbers had been logged out. The reason for the cancellation is not complicated, but it is only because the account has been in arrears for more than 3 months. In this case, it is not surprising that the caller may have changed to a new mobile phone number and abandoned the original mobile phone number.

According to the call records, Li Mei dialed the cancelled mobile phone number and spoke to her on March 29, 2019, and the call lasted 12 minutes. This indicates that the number should have been in normal use until then, after which it was deprecated and eventually cancelled. At the same time, this is also the last call record of the mobile phone number under Gui Ying's name used by Li Mei.

In addition, according to the feedback of the residents of the harmonious community and Gui Ying, the time when Li Mei disappeared in their eyes was about "more than half a year", which is highly consistent with "March 29, 2019". In other words, Li Mei suddenly disappeared after making that phone call, until the Baitu copywriting broke out, the task force intervened, and through various assumptions and counter-deductions, it was finally determined that the deceased was Li Mei.

This cancelled mobile phone number is extremely suspicious, who is the person who used it to talk to Li Mei?

After the mobile phone number is cancelled, ordinary people cannot query the personal information of the original owner through general channels. However, the public security organs are not ordinary people, and their inquiry channels are certainly not ordinary.

The mobile phone number is cancelled, even if the number is no longer bound to the individual's ID number, there are still relevant registration and cancellation cases within the operator. For the purpose of handling the case, the public security organ sent a letter to the operator to inquire about the owner's information, and the operator queried through the innermost system. The department provides relevant information about the original owner of the number.

With the great attention of the task force, the operator fed back the query results to Duan Ming. The original owner's name was Li Haijun, along with his identity card number.

After investigation, Li Haijun was not a staff member of the welfare home, nor was he a vulnerable person living in it. At the same time, there was only one word difference between Li Haijun and Li Haidong, which immediately attracted Duan Ming's attention. Through further retrieval of Li Haijun's identity information, it was found that his ID photo was exactly the same as that of the Wang brothers.

Wang An and Wang Kang, Li Haidong and Li Haijun, the dual identities of the twins can be regarded as complete. But the question arises again: Wang An and Wang Kang, which one of Li Haijun and Li Haidong correspond to?

Therefore, under the condition of only obtaining information on the student status of Wang An and Wang Kang, Li Zhudao once again divided the criminal investigation team into three and visited the schools where Wang An and Wang Kang had studied, in addition to wanting to deepen their understanding of them, trying to analyze the "long-term" causes and factors in their personalities, and seeking motives for committing the crime, but also to distinguish them and correspond them to Li Haidong and Li Haijun.

With the continuous collection of information on the visits of the two groups, the correspondence between Wang An, Wang Kang, Li Haijun and Li Haidong has become clearer and clearer.

It is worth mentioning that the mobile phone number of Wang Kang fed back by Lao Liu is the same as the mobile phone number cancelled by Li Haijun, which is the same number. This seems to mean that Wang Kang should be Li Haijun.

But the opposite is true.

"After graduating from the college entrance examination, it should be Wang An who still keeps in touch with Teacher Liu Hui. The two brothers lacked fatherly love. Judging from the information fed back by Lao Liu, when Wang An replaced Wang Kang in Shashi No. 1 Middle School, he was disciplined by teacher Liu Hui. This most likely gave Wang An an emotion of seeing him as a father. Therefore, Wang An still keeps in touch with Mr. Liu Hui after studying in college, and when he participates in life events such as work and marriage, he will call Liu Lao to report the good news, which on the surface is the student reporting the good news to the teacher, but in fact, in Wang An's view, he is very likely to regard this as the etiquette that the younger generation should have to the elders, and even a way to communicate between father and son. ”

Li Zhudao looked at the small blackboard in front of him and said. There is a small blackboard in his office, on which he notes the characters of the case and the relationships between them, as well as some important points in time, and connects these times and characters with various lines that only he can understand. Now, this blackboard reads Li Haidong, Li Haijun, Wang An, Wang Kang, Li Mei, Wang Fang, as well as the time of the crime, as well as the time of Li Mei and Li Haijun's phone call.

"Wang An's personality is extroverted and jumpy, and the 'Wang Kang' who keeps in touch with him described by Liu Lao is in line with Wang An's personality traits. The real Wang Kang, whether in terms of personality traits or from the psychological process of being raped twice, is not as described by Liu Lao. ”

In addition, Wang An gradually started his own business after graduating from university, which is consistent with Xiao Ming's feedback that Li Haijun had registered a company under his name.

Further inquiries into Li Haijun and his ID number revealed that Li Haijun had founded an agricultural development company called "Genesis" in Qinghe City, a southwestern border province, but the company had been deregistered with the industrial and commercial institution due to bankruptcy in May 2018.

The reason why Li Haijun is said to be "before his death" is because according to the query of his name and ID number, this person has died, the time of death is March 29, 2019, the cause of death is a traffic accident, and the location is Yongcheng.

What does the time of Li Haijun's death coincide with the time when he and Li Mei talked on their mobile phones? If Li Haijun made the last phone call to Li Mei, who was far away, before he died, this would make perfect sense logically. But that phone call was made by Li Mei to Li Haijun. Li Mei called Li Haijun before his death, is it a coincidence, or is there something else hidden?

In addition, Duan Ming traced the mobile phone number assigned to Li Mei by Gui Ying, and found that the signal source of this mobile phone number finally disappeared in the Baituwen community. When I first visited the scene, I found many cards, as well as traces of the physical destruction of mobile phones. Physical destruction can be done by burning or shattering with hard objects. After technical restoration, a smartphone was found, but the information could not be extracted. Mr. Li uses an old-fashioned mobile phone that requires keystrokes. This smartphone should be the one that Gui Ying equipped with Li Mei.

Li Zhudao temporarily withdrew his doubts and thoughts, and continued: "So, whether it is from Liu Lao's feedback or from Wang An's character, Li Haijun should be Wang An, and Li Haidong is Wang Kang. ”

Wang Kang's dissatisfaction with his mother Wang Fang, coupled with the two tragic experiences before the college entrance examination, caused his mood to be more depressed, his psychology more distorted, and his personality more extreme. Before the case, it is very likely that there were some contradictions between him and Wang Fang, and the dissatisfaction accumulated for decades exploded, and then he killed people and broke up his body in anger......"

Xiao Wu, who was standing behind Li Zhudao, was tall, looking like he was listening carefully to Li Zhudao's analysis, inferences and summaries.

Li Zhudao turned around and saw Xiao Wu's pair of jet-black eyes rolling around in his sockets, so he said very dissatisfiedly: "Day by day, you are always absent-minded, you have to learn something." Otherwise, what would I keep asking you to do with me? ”

"I'm listening." Xiao Wu looked directly at Li Zhudao, with a good and impeccable attitude.

"What did I just say?"

"You're saying a good job, and I'm in favor of it."

"I ask you, what did I just say."

"You're right, there's nothing wrong with that."

“……”

Li Zhudao sighed and asked directly: "Wang Kang is Li Haidong, the reason why he killed his mother Wang Fang, we may be able to speculate from the information fed back by Lao Liu and Ouyang." The shredding of Wang Fang's body can also be understood as Wang Kang's excessive dissatisfaction accumulated over the years, but why did he expose his crimes in the WeChat group? It's not to show off, but for what purpose? ”

"You don't know?" Xiao Wu's eyes widened and asked.

"You know?" Li Zhudao was a little surprised.

"I don't know." Xiao Wu still didn't change his face, and rolled his eyes with confidence.

Li Zhudao sighed secretly, and had to give up the idea of guiding Xiao Wu to use his brain again, and said, "Inform Lao Liu and Ouyang and ask them to continue to collect clues and information about Wang Kang when he was in college." Focus on whether anyone suddenly disappeared or was killed after Wang Kang re-enrolled in the college entrance examination, that is, from June 2003 to July 2005, when his classmates, friends, and even near the place where he lived, such as the university where he studied, or were killed, but the murderer has never been found. ”

"Why?" Xiao Wu suddenly became interested and asked.

"The formation of Wang Kang's criminal psychology and behavior is incoherent."

"Serial murderers often do not commit crimes intentionally for the first time, most of them are manslaughter or crimes of passion, but the murder is not solved later, which causes the murderers to get away with it for a short time, and at the same time opens the Pandora's box of their heart's desire to commit crimes. For some people, crime is like sucking. Poison, once contaminated, will become addictive. ”

"After Wang Kang was raped by Wen Tao and others in June 2002, by June 2003, his psychology and emotions should not have been completely out of control during this time, otherwise, he would not have been able to repeat his studies quietly for a year, but he should also be at a critical point of losing control."

"July 2005 was the time when Long Zhiyi disappeared or was killed, in July and August 2006, it was Li Yi and Huang Zui, respectively, and in August 2007, it was He Xiaoyue. Obviously, the disappearance and murder of these four people one after another is more likely to be Wang Kang's revenge and premeditated murder. Judging from the time when these four people disappeared and were killed, they were all during the summer vacation, and Wang Kang had plenty of time to make careful plans. ”
