Du Dayong couldn't help but applaud, and finally gave Wang Qian a thumbs up.
"That's right. It seems that you really worked hard when you were a co-police officer! The analysis is quite good and the starting point is quite reasonable. I will not comment for now and will listen to what Tu Qijun has to say."
"Du Suo, I still listened to what you said. I went to the wall on the other side of the dirt road with my flashlight. There were no traces of people stepping on the wall, but there were traces of people staying for a long time near a bush. I
I looked at the dead leaves on the bushes again, and found that there were basically no dead leaves at all in one area, but there were scattered dead leaves in other places, so I had to suspect that the suspect had certain counter-investigation capabilities."
"So I think that in that area, the suspect may have changed his clothes. Then when we get information from the outside, there is no way to get the information about passing by wearing a black sportswear. Then I consider the crime
Since the suspect was able to change his clothes, he must have carried a backpack or a bag in and out. After all, I didn’t find any traces of buried clothes in that area, so the clothes he changed must have been taken away. Then the man who ended up with a backpack or a bag
That’s the key suspect I’m looking for.”
Wu Shengning looked at Tu Qijun with some head scratching.
Du Dayong understood at a glance that Tu Qijun probably didn't share this situation with these two people. It was probably that the three of them observed it together when he was using the flashlight. Tu Qijun deliberately didn't say anything because he wanted to see if the two people would
You can see or think of this possibility.
Thinking of this, Du Da looked at the three people with encouraging eyes and said.
"You are all right. Tu Qijun obtained some intelligence information before you did. This is also to train your analytical ability and thinking expansion ability. Don't think that he deliberately didn't tell you. At least I don't think Tu Qijun is like that.
of a policeman.”
"Wu Shengning's idea of starting from age and then searching for suspects through platooning is correct. But where is the deviation? In my opinion, there is only one point. The certainty of the assumption is too strong. In layman's terms, it is too subjective.
Strong, objectivity is a little weaker, this needs to be corrected in the future. If you want to become a criminal policeman in the future, this is a big taboo. Subjective judgments must be denied objectively. Only when objective conditions cannot deny the subjective judgments, can we think
This subjective judgment is basically reasonable, remember, it is still basic, because it cannot be ruled out that other factors that appear in the follow-up period of the case will affect the previous subjective judgment."
Wu Shengning nodded repeatedly as he listened, and the words on his notebook were written like dragons and phoenixes.
"Wang Qian, the insights and opinions you put forward show that you have put in the hard work. Here I will briefly talk about your shortcomings. You must know that the cause of a case is often not just one or a few things.
You said that the criminal suspect may be laid-off and unemployed, have a normal family, and may be a man living in such a dormitory. These opinions only include part of the elements of the case."
"Since we can think of these, we must have extended considerations. Even if a person reaches the point you mentioned, he will definitely commit robbery? Because you also said it is obscene, it may mislead our police, so let's take this now
Putting it aside. Who would commit robbery in the situation you mentioned? You also mentioned the reason of low family status and the need to bring money home, more or less. The most important point is
What is it? Does the suspect commit crimes frequently?"
"Assuming that Xi Juan is just one of the people who dared to report the crime, then there is only one man who has called the police so far. What does that mean? The frequency of criminal suspects committing crimes is far less high than you think. Now he works normally in Zaozhuang and earns a monthly income How much is it approximately? Three to four hundred should be about the same, right?"
Wang Qian nodded as he listened, and like Wu Shengning, he quickly took notes and wrote down what Du Dayong said.
"It is known that the two cases that were reported to the police were separated by a period of time, 227 and 11, adding up to 238 yuan. I plan to have some cases that were not reported to the police, and they should all be small amounts. Really The amount is so big, who can care about their face and not call the police? Is this robber really a laid-off and unemployed person? I hold the opposite view to yours. This robbery is half true, and the obscenity is completely true."
"Since the criminal suspect can wear a special black sportswear, it means that this black sportswear must be universal. Don't forget that there are technical schools and technical secondary schools in our jurisdiction, and there must be many students with such a set of black sportswear. In this way, even if the victim reports this problem, will our search range be very wide? Will the probability of finding him be reduced? "
Wang Qian nodded sheepishly and smiled.
"Judging from the frequency of crimes committed by criminal suspects, robbery victims are more likely to mislead our police, asking our police to investigate people who are short of money. So are there more people who are short of money or people who are rich?"
"Du Suo, there must be more people who are short of money." Wang Qian said quickly.
"When we investigate people who are short of money, we will lessen the investigation of those who have money, or even not investigate them, because people have a habitual mentality. If you have 100,000 yuan, will you rob others of 11 yuan?"
"I can change my clothes. I also know that many people in the student group have black sportswear. They just want to be obscene. I'm not financially strapped. Is there any consideration?"
After Du Dayong asked, the three of them shook their heads.
