The first thousand two hundred and two chapters can't afford time and money
During the meeting of the 527 task force, Bao Feiyang sat in the middle. On his left was Jiang Fangchang, the captain of the Criminal Investigation Detachment, and on the right was Shi Dongming, the special consultant expert of the 527 task force. Reading, the deputy detachment of the Criminal Investigation Detachment and Lin Qianqiu, the captain of the Technical Investigation Brigade, sat next to Jiang Fangchang and Shi Dongming. As for the other task force members, they all sat down according to their usual positions.
Bao Feiyang took out a cigarette, put it under his nose and smelled it. He laughed and called out, "Although I am the director of the police station and I am temporarily in charge of criminal investigation work, I will tell you that I am a layman who knows nothing about criminal investigation work. Therefore, today's protagonist of this case discussion is the elites on the criminal investigation front. I am here today to listen to the study. You just need to discuss it, don't worry about me!"
"Director, you are so humble!" Jiang Fangchang said quickly, "Although you have never done criminal investigation before, there is a saying that goes, "The authorities are confused, and the bystanders are clear." There are many things. According to the traditional criminal investigation thinking, we are prone to going to the dead end of our thinking and cannot find the answer. However, outsiders do not have the traditional criminal investigation routine thinking pattern, but can look at problems in a wild way, so as to give us a way to solve the case from another perspective."
Jiang Fangchang's flattery made people feel full of flowers, which made Reading, who was sitting on the other side, shook his head and admired. No wonder Jiang Fangchang was able to be the top leader of the Criminal Investigation Detachment. The level of flattery alone was far inferior to his deputy!
"Haha," Bao Feiyang also laughed, knowing that Jiang Fangchang had just turned to him and had no idea, so he looked for every opportunity to express his loyalty to him so explicitly. From this point of view, although Bao Feiyang does not like being flattered like this, it is not easy to show it, so as not to discourage Jiang Fangchang's enthusiasm to move closer to him.
"Old Jiang, let you say this. I also feel that I, an outsider, have strong confidence in criminal investigation work! However, although the bystander's thinking sometimes can look at problems from other perspectives, it is not the norm after all. In criminal investigation work, most of you still have to rely on the rich criminal investigation experience accumulated by you comrades who have been working on the criminal investigation front for a long time to improve the efficiency of case investigation. For example, the old comrades on the criminal investigation front here, especially Shi Dongming, are our biggest reliance on the May 27th theft case this time!"
Speaking of this, Bao Feiyang smiled again, "Okay, let's say so much about the opening remarks. Let me ask Mr. Shi to talk about his discovery of this on-site survey."
"Director Bao, I have reported to you before about the finding of a mosquito corpse containing the blood of the suspect on the vehicle that occurred. I have also conducted detailed analysis to the comrades of Jiang Detachment, Lei Detachment and the task force. I will not repeat it here. Now, Wang Xinxin, a police officer from the Technical Investigation Brigade, has sent the mosquito corpse to the Physical Evidence Identification Center of the Provincial Police Department for testing. It is expected that the DNA test report of the blood sample in the mosquito corpse will be obtained as soon as three days."
Shi Dongming still spoke slowly and his voice was not high, but it made everyone in the conference room hear every word he said clearly.
Bao Feiyang nodded. It is now 199, and DNA detection technology is not as popular as it will be in the future. In northern provinces, only the Provincial Police Department’s Physical Evidence Appraisal Center has the technical capabilities for DNA identification. The Fenglin City Police Department does not currently have equipment and technology in this area.
"Old Shi. Being able to find the DNA sample of the suspect is undoubtedly a huge breakthrough. But it is not enough to have the DNA sample of the suspect. How can we find the suspect based on this DNA sample?"
Bao Feiyang raised his own question, which he wanted to raise when Shi Dongming reported to him in the office just now. But when he thought that he would hold a special task force discussion meeting, Bao Feiyang decided to put this issue at the special task force discussion meeting, so Shi Dongming had to talk about it again. In this era, DNA testing is still a very cutting-edge technology and has not been popularized in China for a long time. Therefore, even in the police system, even if some DNA samples of criminal suspects are retained, there is only a very small number, and there is no large-scale DNA sample library for criminal suspects. Therefore, it is impossible to use the DNA samples of criminal suspects to search for criminal suspects from the DNA sample library.
"Director Bao, there is indeed the problem you mentioned." Shi Dongming looked confident and every wrinkle on his face was shining with the glory of wisdom. "But this problem is not difficult to solve. We can enclose specific target groups, then DNA samples of these specific target groups, and then compare them with the DNA samples of the suspects we already know, so that the suspects in the 527 car smashing and theft case showed their true colors."
"Old Shi. How do you choose this specific group of people?" Jiang Fangchang couldn't help but ask, "What if the suspect was a wandering criminal from another place and left our northern province after the case was completed, then where would we collect his blood samples?"
"The possibility of this case being committed by a traitor from other places is very small. The biggest possibility is that the local theft criminals in Fenglin City are doing it!" Shi Dongming replied.
"The traversing offenders may be very small? The biggest possibility is that our local theft criminals in Fenglin City did it?" Reading was also very surprised, "Master, where did you judge it from?"
"This is not difficult to judge. Please see the photos of the crime scene!" Shi Dongming stood up, turned on the slide projector, and projected the photos of the crime scene onto the screen behind him.
"The location where Chairman Wei Sihua's Mercedes-Benz's vehicle is located on the inner side of the parking lot. In addition to the exit in the south, there is a very inconspicuous exit on the wall-mounted corridor behind the wall. According to a comrade from the Security Department of the First People's Hospital of the Municipal People's Hospital, this small exit is almost locked out of the hospital for transporting medical waste. After walking out of this exit, there is a remote alley outside, which has to be twisted and turns and turns to walk more than 200 meters before you can reach Qingquan Road..." Speaking of this, Shi Dongming paused for a moment, "If it weren't for a local person who was very familiar with the First People's Hospital of the Municipal People's Hospital, he wouldn't know that there was this exit."
"According to the analysis of suspects in the theft case of smashing the car window glass, when they choose the target of theft, they will first observe the retreat to prevent theft from being blocked inside and unable to escape when the theft is discovered." Shi Dongming continued, "So, if it is a crime committed by a wandering crime, the vehicle near the docking position of Chairman Wei Sihua will not be chosen as the target of theft, because it seems that there is only one exit and it is easy to be blocked inside."
"And according to the data of the car smashing and theft cases that have been solved, most of the places where the tramp commit the crime are bus stations and near the railway stations, so that they can quickly escape to other places when committing the crime." Shi Dongming turned another page, and a page of information was displayed on the screen. "There have never been any tramping and theft cases of tramping and theft cases in the bus station like the First People's Hospital. Therefore, I suggest that the collection of DNA starts with the local theftsmen in Fenglin City."
"Even if we start collecting DNA samples from local thieves in Fenglin City, it is a very huge number!" Jiang Fangchang pondered for a moment and said, "According to the information I have at hand, there are 400 thieves registered in our Fenglin City police system. If all DNA samples of these people need to be collected and tested, it is an extremely huge data, whether it is the time cost or the capital cost of technical testing!"
Bao Feiyang nodded, Jiang Fangchang's concerns were reasonable. If these more than 400 DNAs that were used to steal were tested, they would not consider the time, just say that the capital cost was the cost. According to the cost of testing a suspect's DNA of 3,000 yuan, it would require more than one million yuan. This is undoubtedly an extremely huge capital expenditure for the Fenglin City Police Department, which is not too abundant!
