Chapter 36 Chapter Thirty-Five

At this moment, Wang Gedong obviously never dreamed that Xu Zeng's American friend was the murderer.He asked for Chen Jin's phone number, just to restore Gan Jianing's past interpersonal relationship through different people. Since the incident, there are few clues, and the murderer never showed up when he killed. Wang Gedong repeatedly considered the case and looked for a breakthrough in the investigation, but it was still difficult to make progress. This can only be done through Gan Jianing's interpersonal relationship. The whole case is divided into two stages, one is the process of the murderer killing Jiang Xiaobing that night and transporting him out of Anle Road; the other is the kidnapping process in the next few days.

The second stage of kidnapping leaves almost no room for police investigation.The mobile phone number used by the murderer can’t be traced. The murderer’s voice must have used a voice changer. The chemical materials used in the crime can almost be determined to be made by himself. The criminal tools, such as two suitcases, are even more ordinary. up.In addition, the terrain of the Nanhu Reservoir is remote, and there is no surveillance on the road. Obviously, there will be no witnesses to see the murderer hiding the box and sinking the corpse at the bottom of the lake. The only thing that is of any use is the first stage of the crime.

The murderer deliberately showed up on the surveillance. Wang Gedong asked someone to adjust the surrounding surveillance on the night of the crime to carefully search for the fat man to see if he took off his hat and mask when he passed by other surveillance cameras, but the fat man never appeared in other surveillance.It seems that after he walked out of Anle Road, he left around other unmonitored road sections. But after all he showed up, and his height and build were recorded. According to the analysis of imaging experts, the murderer's height is about 174 to 176, which is the height of wearing shoes. Visually, it is a pair of leather shoes, and the height of the shoes is generally about three centimeters.Adding some margin of error, the actual height of the murderer with his shoes off should be between 170 and 174.Due to the heavy clothes in winter, it is impossible to accurately judge the weight. We only know that the murderer weighs at least 150 catties.

With the basis of height, if the murderer is really Gan Jianing's classmate, it will be easy to handle.Just retrieve the physical examination reports of the students of Gan Jianing's five years before and after—because you have to consider that the murderer may not be a classmate of Gan Jianing's class. In the physical examination report, all those whose height meets the standard are listed, and then excluded one by one. The Department of Chemistry is a small major. There are more than 100 students in the fifth grade. It is estimated that there are at most 60 to 70 men who meet the height standard. It is necessary to check one by one. Although the workload is still a bit heavy, it is the most feasible at present. Method.

As for the weight, it can only be used as a reference. After all, the weight in the physical examination report back then is very different from the situation more than ten years later, only the height remains unchanged.Of course, after listing all the people who fit the height, we can see who are fat people one by one, and the scope of the investigation can be greatly reduced. Wang Gedong knew very well that as long as the murderer was Gan Jianing's old classmate, he would definitely fall into the police's sight soon. But there are at least two murderers. Jiang Xiaobing transported them out by car.The car that drove off Anle Road that night, among the more than fifty car owners, Fatty had already been excluded.This shows that one of the more than fifty people is Fatty's accomplice, but the other party has a good psychological quality and was not questioned by the police.In the absence of evidence, it is almost impossible to directly ask who is the accomplice from more than 50 people.

So the goal is to go back to the known fat man. Among the two murderers, one must have a professional background in chemical engineering.None of the more than 50 car owners has it, so it proves that the fat man has a chemical background. ——Of course, there is another possibility that the background experience of more than 50 car owners is faked, but it is undoubtedly a more difficult job to check the detailed background information of more than 50 people. Now I can only hope that the background experiences of more than 50 car owners are true.Then we only need to investigate Fatty. Since the current assumption is that the fat man has a chemical background, if the murderer is really a classmate of Gan Jianing or a relative or friend in the chemical industry, this person is undoubtedly the fat man, not one of the car owners.

But Wang Gedong still couldn't figure out one thing. In such a big case to be executed, the fat man came to avenge the crime. Why would the accomplice who is not in the chemical industry help him? Is the accomplice male or female? What is the bond of interest that makes the two people unite and dare to commit a major shooting case? This problem can only be figured out when the fat man is captured. Now the idea is clear, as long as the fat man's height and weight are compared with Gan Jianing's acquaintances and classmates one by one, are you afraid that you won't be able to find it?

The subsequent detection work has a clear direction. The first is to check the physical examination reports of the five classes before and after Gan Jianing, listing those who meet the height requirements and currently weigh more than 150 catties. The second is to give some of Gan Jianing's former acquaintances and classmates the photo of the fat man wearing a hat and mask to identify who he looks like in appearance. The third is to continue to investigate the owner of the car on the night of the incident, maybe there will be unexpected gains. The fourth is to quickly restore Gan Jianing's interpersonal relationships from her acquaintances and classmates, including interpersonal relationships after work, and find out all her relatives and friends who are engaged in the chemical industry.

Well, I have finally broken down many problems that I didn't think to understand before. Next, I will talk about the situation with Xu Zeng's friend Chen Jin today. Wang Gedong considered that the other party is in the United States, with the opposite time difference. If he calls during the day and the other party is still asleep, how can he cooperate with you in handling the case? The police are very good in China, no one dares not to cooperate with the investigation, but the other party has lived in the United States for more than ten years, his whole family has immigrated, and he does not plan to return to China to make a living, how can he give you face from the county police bureau?

So Wang Gedong waited at the county bureau until 10:30 p.m. for the sake of being polite, and then he called a policeman with a master's degree who had just been admitted to the civil service to make a call for him. Because Wang Gedong could not speak English, although Chen Jin was Chinese, it might not be him who answered the phone, so Wang Gedong asked the master student to stay with him before leaving get off work. When the time came, his subordinates dialed the phone according to the instructions, talked to Ji Ligulu for a few minutes, and hung up. Wang Gedong asked strangely: "Why did you hang up? I haven't spoken to him yet?"

The master student said, "This call has been changed." Wang Gedong couldn't help wondering: "What's going on?" "The person who answered the phone was a young American. He said that they had rented this house through an intermediary more than three weeks ago. I asked him if there was a Chinese named Chen Jin. The other party said that the owner of the house in the rental contract was named Chen Jin, I heard from the agent that the owner of the house was sent by the company to work in other states, so the house was vacated for rent. I asked him if he had the contact information of the owner, and he said no. Boss, should I ask the other party to provide the contact information of the agent? , let's find Chen Jin's latest contact number through an intermediary?" Wang Gedong shook his head and said, "Forget it, it's really troublesome to deal with people across the country. Anyway, Gan Jianing has more than one classmate, and I can't get in touch with him here. Let's find other people in China." At least this phone call didn't make Wang Gedong suspicious of Chen Jin yet.It is precisely because the house was only rented out three weeks ago that Wang Gedong never dreamed that he actually returned to China two months ago.But he will ask Gan Jianing's classmates for verification, and he has the "fat man"'s height and weight data. As Gan Jianing's classmate, can Chen Jin run?
