Chapter Errors/Click here to report

The 'harmony and peace' operation of the Luxi City Public Security Brigade thundered heavily and rained little, and for two days, although some petty thefts were caught, there was still no progress in the case of smashing cars and robbing them. Please be familiar with the domain name

A large number of clues gathered in Du Long's hands, but this made the case even more confusing.

Putting aside the clues that Du Long obtained from other channels, Du Long found that this group of car smashers and robbers can be called criminal geniuses, and their criminal behavior has almost no rules to follow, and even every time they act, the members are male and female, more and less, and the crime scene is also all over the urban and rural areas of Luxi City.

However, the fact is that there are professionals who are proficient in the methods of the police to arrange the actions and report the robbers, and the robbers are well aware of the cameras everywhere.

Du Long asked the policewomen of the household registration department to help input the information into the computer, including Ouyang Ting, a large number of jù became clear after entering the computer, Du Long and other numbers jù were almost entered, he sent the number jù to Yue Bingfeng, Yue Bingfeng used the software to help him gather all the numbers together, and after the software automatically eliminated a large number of useless jù, the true face of the series of car smashing and robbery cases was gradually revealed.

On Thursday night, Du Long called the police officers in charge of investigating the case together for a meeting, and used the projector in the conference room to analyze the case.

"Now is the era of digital informatization, and when solving some more complex cases with more clues, the statistical and analytical capabilities of computers can play a great role......

Du Long said: "For example, in this case, there are so many clues, even if you read all the clues once, it will take a day or two, after reading these chaotic and large number of clues, it is estimated that the whole head has become like a paste, at least I am like this, I believe everyone is similar, right?" ”

Everyone chuckled, Du Long continued: "After using the computer to summarize the number jù and statistically, the situation is much simpler, everyone look at this picture, this is the first chart of the statistical system after entering the computer with the number jù you gave me, that is, the simplest map of the time and place of the crime, and it is dynamic, we can see when and where the most recent case happened from the first case......"

Du Long clicked the mouse, and the map changed, and he circled the location of the crime on the map with a hammer and a stick in the west, and marked the time next to it.

"I know that you may have drawn such a diagram yourself, but obviously it is not as clear as it is with the computer table, this is still the simplest computer application, and what is more useful is the next number jù statistics and analysis ......"

Du Long showed the members of the public security brigade an unprecedented, using the computer to analyze the shape of the case, the more clues entered, the more obvious the advantage of the computer, Du Long casually pulled out a delicate questionnaire, entered the recent activities of a person who has been convicted of robbery and theft, and the computer almost did not take time to rule out the suspicion of this person, and showed that the time of a certain crime contradicted the evidence of the person's alibi.

"The computer can analyze more than just the number of time, they will carefully analyze the height of the target, whether the body is left-handed, etc., you brought me a total of more than 800 survey papers, if you use human analysis one by one, it is quite time-consuming, and people often make mistakes, the computer is not, I asked the female police officers of the household registration department to help me enter the more than 800 numbers you got back, let the computer screen it...... Everyone took a closer look at ......"

Du Long pulled up a file and said, "What is in this file is more than 800 materials that you sent me, open it with this analysis software......"

A red progress bar appeared on the computer screen, showing that it was being analyzed, and the progress bar quickly ran to 100%, and then directly popped up a screen of avatars.

"More than 800 targets have become seventeen, and the workload has been reduced by hundreds of times, which is the benefit of computers, of course, to get accurate results, the computer has to rely on everyone's efforts to collect clues...... Otherwise, the computer will become blind and deaf, and the remaining seventeen target computers think it is more suspicious, and you can find that Hou Xia's subordinates are not among them...... Now I'll let it take turns for everyone to take a look at the information of these people, and after reading it, everyone will tell me who is more suspicious. ”

Du Long handed out a blank piece of paper to everyone and asked them to write down their suspected targets while looking at them, and then tapped the first avatar, and a photo of a suspect appeared in front of everyone along with various numbers.

After reading it, Du Long took back the blank paper on which his name was written, he took out Zhao Congguo's one, glanced at it, and said with a smile: "Zhao Congguo, why do you suspect these six people?" People don't have a history of smashing and robbing. ”

Zhao Congguo said: "These people are because they did not smash and rob the past, so in the previous few investigations, we did not pay enough attention to them, now seeing the results of the computer's analysis, I suddenly realized the mistakes in the past, these people I am familiar with, they used to be a theft gang, after the labor camp was dispersed, I have not heard that they are together again...... They actually left Luxi City almost at the same time and didn't know where to go, this ...... It's all too obvious......"

Du Long said: "Yes, the clues that are usually easy for everyone to ignore, once they are gathered, they will become very obvious, now, I suggest that everyone focus on these seventeen people, of which these six are the top priority, everyone should do their best to verify whether they were involved in the crime, and then find out where they went, do you have any opinions on this decision?" ”

Everyone discussed with each other and shook their heads, there were too many goals in the past, and everyone was like a blind man touching an elephant to catch who to check whom, but now that there is such a clear goal, everyone naturally has no opinion.

"Then you go and check, or Zhao Congguo is in charge, Lao Yang, what do you think?"

Yang Changxian said: "I have no opinion, just do it." ”

After the meeting, Yang Changxian sighed, saying that he had seen the use of computers to handle cases, but he had never seen such a powerful one, and said that he was old and was going to be eliminated by the times or something.

Du Long smiled: "What kind of old man is only in his early thirties...... There is nothing special about computer investigation, the real heroes are those programmers in addition to the investigators who work hard to investigate, without them to write more and more useful programs, the computer is an iron lump, Lao Yang, and when this case is over, I consider applying to the leader to build a computer automated office system, and everyone will use computers to work in the future. ”

Coming out of the security brigade, Du Long looked at the time, the police car suddenly turned into a parking lot, and when he came out of the parking lot, Du Long had already changed into a set of regular clothes, and he was still carrying a small bag in his hand, he pressed the Bluetooth headset as he walked, and asked softly: "How is the situation now?" She's okay, right? I'll be able to get to ...... in about five minutes."
