Chapter 56 Chapter Fifty-Five

In the afternoon, Lin Jie came back to report: "Boss, Liu Zhiyong has made arrangements to watch him 24 hours a day. His cell phone has been monitored and all calls will be recorded." Wang Gedong let out a tired breath, sank deeply into the chair, closed his eyes slightly and said, "But I don't think Liu Zhiyong will be the murderer." "Why? Didn't he lie, and he went to the county the day after the incident, and his height and occupation meet the requirements of a murderer." Wang Gedong shook his head: "The problem is that he arrived in Jin County the next day. If he really did it, why did he drive his own car on the expressway blatantly to our county on the second day after the incident?"

"He may have done this deliberately to conceal that he was in the county on the night of the 19th. After the attack, he returned to the urban area and drove on the expressway in the afternoon of the 20th, making us mistakenly think that he left the urban area on the 20th. , to stagger the incident time." Wang Gedong still shook his head: "There is no need for this. The murderer committed suicide from a distance in the two crimes. So far, we have not been able to obtain any direct evidence such as footprints and fingerprints of the murderer. Of course, the murderer himself is very clear about this. We With the clues we have, we can't directly suspect a specific individual. If Liu Zhiyong really did it, why did he deliberately attract our attention before we can't suspect him? In addition, he came to the county on the 20th to visit He's house. And he has never been there before, the murderer will not deliberately expose himself, let us investigate him."

Lin Jie said, "Perhaps he just did the opposite, and intentionally made some unreasonable actions?" "Then let me ask you, why did he hide that he was Gan Jianing's ex-boyfriend?" Lin Jie looked blank: "Yeah, why did he? What did he say?" "He said that because his relationship with Gan Jianing was very short and the development was not deep; on the other hand, he hid the past in his heart and didn't want to mention it, nor did he want to cause trouble for us and himself. If he is the murderer, it doesn't make sense We will deliberately conceal the information that he is Gan Jianing's ex-boyfriend, because sooner or later we will know this information by asking their other classmates."

Lin Jie sighed in frustration: "If he is not the murderer, then this case will be difficult to handle. Just at noon, I received news that Wu Gang has been working in Canada, and he has canceled his domestic household registration. People from the Municipal Bureau sent a fax to the local police A letter confirming that he had never left the local area. The investigation of car owners on Anle Road that day has reached a deadlock. Except for some people who have firm alibi, most of them said that they were at home at the time. Eliminate suspicion." Wang Gedong rested his head on his hands, pondered for a while, and pursed his lips: "This case has been done so far, and the road is very narrow. The other party is too cunning, and has not left any substantial clues except for the clear motive of the crime. The most important thing is the murderer. It is two people, and their identities, genders, and relationships are unknown, which greatly increases the complexity of solving the case."

Lin Jie also had a bitter expression on his face. He had never seen such a vile but sophisticated crime since he was a police officer.In the past, the most important method for the police to handle cases was to visit, but this time they did not get any relevant clues from the surrounding people.Secondly, the monitoring probe, the tool that the police rely on most at present, except for the images deliberately exposed by the murderer, all the surrounding surveillance, including banks, stores, gas stations and other social surveillance, failed to find this "fat man". The environment is extremely familiar, avoiding all monitoring.In addition, there are two murderers. As we all know, gang crimes rarely occur in vendettas that are not for money. It made the whole case even more confusing.

After thinking for a long time, Lin Jie was at a loss as to what to do next, and he only listened to Wang Gedong's arrangement: "Boss, what else can we investigate next?" Wang Gedong took a deep breath, straightened his body, and said in a deep voice: "The conventional detection methods such as investigation of vehicles on Anle Road in the early stage, inspection and monitoring, and surrounding visits have yielded nothing so far. It is difficult to continue to carry out these three tasks. Let's put these three pieces of work aside for the time being, and re-arrange all the manpower. First, we must firmly grasp the direction. The criminal motive of this case is very clear, and it is for Gan Jianing! Second, the murderer's criminal methods clearly expose his identity. We have thoroughly investigated Gan Jianing’s background in chemical engineering, and there were only a few of her colleagues with this level of chemical engineering skills. They have already been ruled out, and the rest are her old classmates or teachers from the chemistry department. We I also know that among the teachers in their department, there is no close relationship with Gan Jianing, and Gan Jianing does not know anyone from the chemistry department of other schools. The rest are her classmates from this school. So although the road we can walk is very narrow now , but the direction is clear and unmistakable, which is to check her classmates from previous and previous classes!"

He paused, and continued: "Dare to avenge and kill the dead Gan Jianing, this feeling must not be simple. From what I learned from many people recently, to restore Gan Jianing's past interpersonal relationships, except for Wu Gang who strongly chased her, Liu Zhiyong once I have been her boyfriend for a month or two. Among the other male classmates, many people have a good impression of her, but it seems that no one is particularly close. But it may also be someone who is emotionally introverted and has a bitter love. Gan Jianing, but did not attract the attention of others, such a person is not uncommon among top science and engineering students."

He continued: "Next, all other work will be put down, and everyone will concentrate on quickly finding out the men who meet the height requirements in Gan Jianing's five previous years!" "Okay, I understand. By the way, what about Liu Zhiyong?" "Find out where he was on the night of November 19th and December 6th. If he is indeed in the urban area, no matter whether he is at home or outside, there will always be several surveillance cameras that will capture him. If he is ruled out as a suspect, Just let him go. Of course, if none of the surveillance cameras have recorded him, then... hum, then you won't be polite to him." Wang Gedong's eyes showed a fierce look.

Lin Jie thought for a while, and said, "Boss, I think we have a problem now. Even if we know who the murderer is, we have no evidence now. If the murderer disposed of all the chemical materials, there is no evidence or physical evidence now. It’s also difficult to deal with suspects.” Wang Gedong frowned: "This is indeed a bit troublesome, but it's not a big problem. As long as we can identify the murderer and arrest him for interrogation for a few days, even if the other party has cleared up all the evidence, we can make him confess." Lin Jie understood what Wang Gedong meant. As long as he knew who the murderer was, he would be caught in the county bureau and interrogated for several days and nights.

Of course, the premise of doing this is that a specific person can be clearly suspected to be the murderer.Now that the police have given up the previous conventional detection methods and concentrated their police forces to investigate Gan Jianing's classmates one by one, how much time does Chen Jin have left to hide?
