Du Dayong didn't say anything, he just looked at the three people and smiled.
"Director, we heard from Tu Qijun that there was some secret in this inquiry record, and we didn't believe it at all. After all, the three of us had been studying it for a long time last night. But Tu Qijun said that this was what you said, director. Wu Shengning and I didn't believe it in the morning. As a result, Now you’ve lost a dinner.”
Wang Qian also said with a confused expression at this time.
Du Dayong took the inquiry record over, spread it out on his desk, pointed to a paragraph and said.
"What did Yang Wuyi say here? Take a look."
"I didn't say anything! I just didn't find anyone in black sportswear coming here, and I didn't hear that anyone was molested or robbed here."
Tu Qijun looked at Du Dayong curiously as he spoke.
"Let me ask you a few questions! First, how long has Yang Wuyi been hanging around this area with public toilets?"
"Nearly a month." Wang Qian replied without hesitation.
"Second, have you checked the map of Yang Wuyi's activity range?"
"Check it! He basically goes to any of the lively places in our area to ask for cigarettes and money."
"Third, Yang Wuyi said, no molestation or robbery occurred in some of the places he visited, right?"
After Du Dayong finished speaking, the three people nodded quickly.
"Okay! Where is the doorway? Can this area be roughly eliminated?"
All three people were shocked.
"Yang Wuyi wanders around this place very frequently, so his behavior is consistent. With this consistency, can we think that these places are not places where the suspect in the obscenity case likes to appear." ωωw..net
"Then can we outline the suspect? He only does things that he feels are relatively safe. Is it possible that he only commits crimes in places he is familiar with? You can now compare Yang Wuyi's scope of activities with the suspects in the obscenity case. If the radius of a person's activity range is drawn as a circle, there must be intersections, so the places where Yang Wuyi moves are relatively lively places in the jurisdiction, which means that the suspect in the obscenity case may also live in this intersection area?"
"Then the suspect in the obscenity case knew that the place where Yang Wuyi was active was an area that he felt was very unsafe?"
"If you draw a circle between the foundry dormitory area and the carriage factory dormitory area, and the radius circle in front, there will be more intersections, and do these intersections overlap with the key suspects you paid attention to in the early stage? ?”
"Even the suspects you are paying attention to for the first time should be reviewed again. The office now has more manpower. We can expand the number of people involved in the case. Don't always think that three people can definitely succeed. Most of the cases I have solved are actually We work together with many colleagues to investigate. It is important to have sparks of ideas, but teamwork is fundamental."
"If you are lucky enough to solve this case, except for the three old police officers who work with you, what do you think other people will think of you? Since everyone is free now, let's find some younger police officers and co-ops from the same station to work together. Expand your participation in detection. This is also a good thing for your growth."
"The other thing I want to tell you is that when you look at the records, you need to have a coherent response, and you need to have drawings and tools to draw pictures at any time. You need to know how to reversely analyze and predict. If you only want the kind of bright clues, then I have to ask you, Do you think the criminal suspects are all fools?"
The three people shook their heads together.
"The most important thing here is time. When does Yang Wuyi basically arrive at what time? Is it from ten o'clock in the evening to two o'clock in the night?"
Tu Qijun nodded again.
"There are only a few intervals known about the time when the suspect of the obscenity case committed the crime. Since Yang Wuyi has never seen that kind of person wandering around the public toilet, what does it mean? It means that the suspect must be there.
In this area, because he has to commit crimes in more prosperous places, will the round trip be long? Once the trip increases, it will take more time for him to travel back and forth. If he wanders outside in the middle of the night, he will not treat us as a patrolman.
Are you a cook?"
"So you can string together Yang Wuyi's time points and see when he is active, the earliest and the latest. How long does it last every time he wanders around?"
"The circle is drawn to roughly determine the suspect's living area, but what about the time? It is in these areas that you find the best way to go to the foundry and carriage factory. So will there be any discoveries in these ways? This is
You need to start running on your own."
After Du Dayong finished speaking, he threw the inquiry transcript on the table directly to Tu Qijun.
"Continue to broaden your thinking. There are still some ways inside. You can open up your ideas a little more, and you can exaggerate your reverse thinking a little more. As long as you are fundamentally cautious and don't mess up the direction, it doesn't matter if you are wrong."
What Du Dayong needs is for Tu Qijun and others to open up their minds, develop dialectical thinking, and research ideas. Only in this way can he make a difference when he encounters more cases in the future.
