Lin Ming's call was made to Zhou Yunkai, and Zhou Yunkai was actually waiting for his call. /p

/p

"Kaizi." /p

/p

"Hmm." /p

/p

"My uncle asked me to ask you if you had any progress." /p

/p

"In fact, this case is only one step away from being solved. But there is one thing I have never figured out, I was afraid of startling the snake, so I never let the police investigate. ”/p

/p

"Which step?" /p

/p

"Computer." Zhou Yunkai said very calmly: "The murderer's house must have a computer, otherwise Y will not be able to get in touch with him." And this murderer must have a habit of writing down his troubles on the computer. ”/p

/p

Lin Ming remembered the inference of Zhou Yunkai and Zhang Shaoan, they said that Y was a master hacker and a computer elite. This kind of person will never kill people with his own hands, and even Y himself is unlikely to be a native of Cloud City, but uses the computer to remotely control the command to do the case. /p

/p

These inferences are all derived from Zhou Yunkai's understanding of Y. He knew that Y was a very thoughtful person with an arrogant personality, and if he wanted to do a case by himself, he would definitely do a very difficult and unbelievable case, rather than an ordinary burglary and murder. /p

/p

It's like in Zhou Yunkai's own opinion, if he wants to commit a crime, he will never do these crimes without technical content. There are too many criminal modus operandi in this world, which will not implicate themselves and keep themselves out of the matter, so why bother to go down to the scene to use knives and guns, and it is easy to leave flaws. /p

/p

Because of this, Zhang Shaoan and Zhou Yunkai agreed that all of Y's actions come from the computer network. /p

/p

Therefore, the inference that the mastermind behind the scenes is looking for the murderer through the computer is also logical. Even as early as the day when he fought with Zhou Yunkai on the forum, he may have hacked into Zhou Yunkai's computer because of his curiosity about Zhou Yunkai, or Zhou Yunkai aroused his sense of victory and defeat, etc., and paid attention to Hu Jie's personal information and had some ideas. Then in the online world of Cloud City, he searched for all the information related to Hu Jie, and finally found a person who wrote a diary or confided in distress on the Internet, and this person must have some deep hatred with Hu Jie, so he contacted him, formulated a murder plan for him, and directed him to commit murder. /p

/p

This is not impossible, on this point, Zhang Shaoan and Zhou Yunkai made detailed inferences. felt that it must be so, so he was suppressed by Zhou Yunkai for such a long time when he logged in to the forum, and it was not until some time ago that he sent a private message to provoke. /p

/p

Because even if you are a computer expert and a top hacker, it is not so easy to find the right person in the online world of Cloud City. /p

/p

So it took a long time, until everything was implemented, and then I came to send a private message to Zhou Yunkai. /p

/p

After listening to Zhou Yunkai's explanation, Lin Ming couldn't help but admire them. Solving the case is really a logical thing, and in a clueless case, Zhou Yunkai and Zhang Shaoan immediately thought of some key points and deduced a lot of useful things. If Lin Minglai was replaced, his eyes would definitely be black, and he wouldn't understand anything. /p

/p

"Alright, I'll tell my uncle this information immediately." Lin Ming suddenly thought that Zhou Yunkai seemed to say that he didn't understand something, and hurriedly asked, "By the way, what point did you not understand?" I'll talk to my uncle and see what clues they have. ”/p

/p

Zhou Yunkai said: "The point I don't understand is very simple, since I can guess that their criminal methods are related to computers, Y must be able to guess as well." As long as you find out who among Hu Jie's enemies has a computer, you can find clues. But I always feel that Y is not such a simple person and will not put the evidence out so easily, so I have been thinking about what kind of way Y will use to get the murderer out of investigation and suspicion. I could even imagine that the murderer's home did not have a computer at all, and even if the police came to investigate, they would certainly not find any evidence in this regard. So I've been worrying about this for the past few days, and I've never told the police about it. ”/p

/p

Lin Ming said: "Could it be that the murderer threw away the computer after killing someone?" ”/p

/p

Zhou Yunkai rolled his eyes and said, "Stupid, can't you check if you throw away the computer?" Not to mention that there are few people who can afford to buy a computer, just talking about the network cable can be easily found by the police. ”/p

/p

"Yes." Lin Ming patted his forehead, solving this kind of thing, sure enough, he is not good at it, he doesn't have that brain. /p

/p

He thought for a moment and asked, "Then should I tell my uncle about this?" ”/p

/p

Zhou Yunkai said that he never figured out what method the suspect Y would use to make the murderer's family never have a computer, in fact, Zhou Yunkai didn't think about this clearly. For example, going to an Internet café, where the murderer often uses the computer in the Internet café to post on the Internet or write a diary, can also contribute to the birth of this condition. /p

/p

But Zhou Yunkai has to be sure that this matter can be investigated by the police, after all, Hu Jie's enemies will be listed in a long list. If you check for the first time, what you will check is where these people were when Hu Jie died, and whether there was any alibi. Then the second check is to check whether these people who do not have an alibi have a computer at home. And then the last time, let's say these people don't have a computer at home, and you have to check whether they often go to the Internet café. In the end, I turned around and found that after three investigations, the murderer was still not found. Such a large investigation work is a very big waste of work and time for the police. /p

/p

That's why Zhou Yunkai said that he had to be sure before he could let the police do this kind of investigation. After all, wasting the police's time is secondary, and I am afraid that this kind of investigation is useless, and the murderer is not in the above three investigations at all, but uses other methods to hide. At that time, this kind of investigation will make the murderer more vigilant. /p

/p

Zhou Yunkai thought for a while, and finally said, "Let's not talk about it yet." I discussed with An Ye again, and I always felt that there was a point that I hadn't figured out, and once I thought of that point, the case would be solved. ”/p

/p

"Okay, hang up first." /p

/p

Lin Ming hesitated for a while, and finally hung up the phone. He didn't say anything about the restaurant, because he thought it was two cases and had nothing to do with Hu Jie's case. /p

/p

In fact, it's not just him, the police also think so. /p

/p

Because there is no evidence of a link between the two cases, the homicides were inherently irregular and at fixed times. It may not be possible for the whole city to come out all year round, and there may be four or five cases on the same day, and it is not without such a time. So neither Lin Ming nor Fang Junlong connected them. /p

/p

When Lin Ming conveyed the reply that there was no clue to Fang Junlong, Fang Junlong fell into distress again. /p

/p

Fang Junlong felt that the case of the Western restaurant was not difficult to solve, because the characteristics of the suspect were obvious, first, he must be familiar with the deceased himself and someone who had an interest in the deceased. For example, you can get an inheritance after death, or you have complaints about the deceased. The second is that hydrocyanic acid is a strictly controlled chemical substance, and it is difficult for ordinary people to get it, so there must be people who are engaged in chemical industry or have very strong chemical knowledge around the murderer. With these characteristics, Fang Junlong is very optimistic about finding clues. But Hu Jie's case really hurt Fang Junlong. There is no physical evidence or clues in this case, although there is a direction for investigation, but so far, there is no feedback. /p

/p

It's like looking for a needle in a haystack, with no clue at all. /p

/p

Let's take a look at the current investigation of Hu Jie's case. /p

/p

It is reported that there is a motive to kill Hu Jie, how long is the list? The investigation of the dossier records was piled up more than one meter high, and so far it has been found that there are as many as 127 people who have been bullied, beaten or hated by Hu Jie. At the time of the crime, except for a few people who needed to work night shifts, such as the bar waiter who was beaten by Hu Jie, most of them did not have an alibi, because everyone was sleeping at that time, even if there were husbands and wives, they could prove each other, and they could not be used as evidence. Because kinship can be perjured, not to mention that while the person next to the pillow is asleep, it is not impossible to secretly go out to kill Hu Jie, and then turn back and continue to sleep. /p

/p

The motive for the crime is currently believed by the police to be a vendetta or love killing, and Hu Jie has women everywhere, often using coercion, snatching, picking up corpses, etc., to force the women in the bar to provide services for him. It cannot be ruled out that some people are jealous and hate them, so they carry out revenge killings. /p

/p

Therefore, this is why it is very difficult to solve the Hu Jie case, because there are only so many lists of motivated murderers found in this case, and there are countless hidden in the shadows that the police cannot find. /p

/p

But if you can't find it, you have to keep looking, it's like casting a net in the sea, you never know if the next net will catch that fish. /p

/p

Hearing that Zhou Yunkai did not give clues in the Hu Jie case, Fang Junlong could only put his mind on the poisoning case in the western restaurant. /p

/p

He is now at the Golden Horn Restaurant, which is open until 8 p.m., and has now been sealed as the scene of the crime. All employees who are working today are currently being investigated and questioned by the police. The technical department and the forensic doctor have taken the teapot back to investigate the source of the poison, and it is expected that the results will be available soon. /p

/p

hung up the phone with Lin Ming, and after a while, the phone call from Director Wang, the leader of the sub-bureau, came. On the phone, Wang Ju's tone was very bad, and he said, "Xiao Fang, how is the situation at the scene?" I heard that it was a poisoning case, and the nature of it was not bad, how was the investigation going? ”/p

/p

Wang Ju has always been more supportive of Fang Junlong, and Fang Junlong told the truth: "Wang Ju, Lao Qiu smelled an obvious bitter almond smell in the teacup that the victim drank before his death, and it was preliminarily judged that hydrocyanic acid was poisoned. ”/p

/p

"Hydrocyanic acid poisoning?" Wang Ju was startled and said: "This is the most dangerous cyanide, this is what the Nazis used to kill people back then." ”/p

/p

"Yes." Fang Junlong said: "Hydrocyanic acid is an item strictly controlled by the public security department, and it is impossible to get this kind of thing without professional chemical knowledge and means." So I think the murderer should have a channel to get this kind of thing, and now the suspect is being investigated, and with this obvious characteristic, it should be easy to find the murderer. ”/p

/p

"Don't take it lightly, there have been waves of unsettled cases in the past few days, and there have been two murders in a row. Although the nature of the first case is not bad, it involves the son of the head of the provincial department, and there is a lot of concern above. Although it is not a sensational case, this kind of highly toxic case is still handled carefully. Once the murderer goes mad and spreads the source of poison, causing large-scale casualties, then you and I must take off our hats and be held accountable. When you're done investigating, call all the officers to the bureau, and we'll have a meeting to talk about these two cases. If there is no breakthrough in the case tonight, including me, everyone will not sleep. ”/p

/p

Neither the burglary and poisoning cases were sensational cases, but in fact, the poisoning cases were a bit of a sideline. But only when it involves multiple casualties, can it be regarded as the kind of vicious case that needs to be accepted by the municipal bureau, the provincial department, and even the Ministry of Public Security. /p

/p

But this is before the case is expanded, in case the murderer is not caught as soon as possible, and the murderer carries out large-scale poisoning to retaliate against society, then Fang Junlong and Wang Ju's career will basically reach its peak. /p

/p

Therefore, the leader of the sub-bureau, Wang Bureau, attached great importance to this poisoning case and decided to crack the two cases as soon as possible to avoid the possibility that the murderer might continue to commit the crime. /p
