In the meeting of the 527 task force, Bao Feiyang sat in the center, with Jiang Fangchang, the head of the criminal investigation detachment, on his left, and Shi Dongming, a specially appointed consultant expert of the 527 task force, on his right. &#读书, Reading of the Deputy Detachment of the O Criminal Investigation Detachment and Lin Qianqiu, the Captain of the Technical Investigation Brigade, sat next to Jiang Fangchang and Shi Dongming respectively. As for the rest of the task force, they all sat in their own positions according to their accustomed positions.

Bao Feiyang took out a cigarette, put it under his nose and sniffed it, smiled and snorted, and said: "Although I am the chief of the police department, and I am temporarily in charge of the criminal investigation work, I will not tell you that I am a layman who knows nothing about criminal investigation work. Just discuss it and leave me alone! ”

"Director, you are so humble!" Jiang Fangchang hurriedly said, "Although you have not engaged in criminal investigation work before, there is a good saying, called 'the authorities are confused, and the bystanders are clear', there are many things, we are easy to walk into the dead end of thinking according to the traditional criminal investigation thinking, and we can't find the answer, while outsiders do not have the mindset of traditional criminal investigation routines, but can look at the problem in an eclectic way, so as to give us a way to solve the case from another angle." ”

Jiang Fangchang's sycophant shooting was full of flowers, making people unable to find fault at all, which made Reading who was sitting on the other side couldn't help shaking his head in admiration, no wonder Jiang Fangchang could be the leader of the criminal investigation detachment, just the level of this sycophant, is far inferior to his deputy!

"Hehe," Bao Feiyang also laughed, knowing that Jiang Fangchang had just thrown himself into himself, and he didn't have a bottom in his heart, so he would be so explicit and find every opportunity to express his loyalty to himself. From this point of view, although Bao Feiyang doesn't like to be slapped like this, it is not easy to show it, so as not to dampen Jiang Fangchang's enthusiasm to move closer to him.

"Old Jiang, let you say that. I also feel that I, as a layman, also have strong confidence in criminal investigation work! However, although the thinking of the bystander sometimes says that it can look at the problem from some other angles, it is not the norm after all. To carry out criminal investigation work, the vast majority of you still have to rely on the rich criminal investigation experience accumulated by you cadres and police comrades who have been working on the criminal investigation front for a long time to improve the efficiency of case investigation. Like these old comrades of the criminal investigation front who are here. Especially Shi Dong Mingshi Lao, it is our biggest reliance on this time to solve the 527 theft case! ”

Speaking of this, Bao Feiyang smiled again, "Okay, that's all for the opening remarks." Next, I will ask Shi Lao to talk about his findings from this on-site survey. ”

"Director Bao, regarding the discovery of a mosquito corpse containing the blood of the suspect on the vehicle where the crime occurred, I have reported to you before, and I have also made a detailed analysis to the comrades of the Jiang Detachment, the Lei Detachment and the task force. I won't repeat it here. Now Wang Xinxin, a police officer of the technical investigation brigade, has sent the mosquito's corpse to the physical evidence identification center of the provincial police department for testing, and it is expected that the DNA test report of the blood sample in the mosquito's corpse will be obtained within three days at the earliest. ”

Shi Dongming still spoke at a slow pace, and his voice was not high, but he made everyone in the conference room hear every word he said clearly.

Bao Feiyang nodded. It's 199, and DNA testing isn't as widespread as it was later. In the Northern Province, only the Physical Evidence Identification Center of the Provincial Police Department has the technical capacity to do DNA identification, and the Fenglin City Police Department does not currently have the equipment and technology to do so.

"Shi Lao. It is undoubtedly a huge breakthrough to be able to find the DNA sample of the suspect. But it's not enough to have a DNA sample of a suspect, so how can we find a suspect based on this DNA sample? ”

Bao Feiyang raised the question in his heart, which he wanted to raise when Shi Dongming reported to him in the office just now. However, thinking that a task force discussion meeting was about to be held, Bao Feiyang decided to put this issue at the task force discussion meeting, and Shi Dongming would have to talk about it again when he got it. In this era, DNA testing is still a very cutting-edge technology, and it has not been popularized in China for a long time, so within the police system, even if some DNA samples of criminal suspects are kept. It is only a very small number, and there is no large-scale DNA sample bank for criminal suspects. Therefore, it is not possible to use the DNA sample of the suspect to search for the suspect in the DNA sample bank.

"Director Bao, there is indeed the problem you mentioned." Shi Dongming looked like he was full of bamboo, and every wrinkle on his face was shining. "But this problem is not difficult to solve, we can delineate specific target groups, and then conduct DNA sampling on these specific target groups, and then compare them with the DNA samples of the suspects we already have, so that the suspects in the 527 car theft case can show their original form." ”

"Shi Lao. How to choose this specific group of people? Jiang Fangchang couldn't help but interject and asked, "In case this suspect is a rogue from out of town and left our Northern Province after completing the case, then where do we go to collect his blood sample?" ”

"It is very unlikely that this case was committed by a wandering criminal, and the biggest possibility is that our local habitual thief in Fenglin City did it!" Shi Dongming replied.

"The possibility of a fugitter doing it is very small? The biggest possibility is that our local habitual thieves in Maple Grove City did it? Reading was also very surprised, "Master, where did you judge it?" ”

"It's not difficult to judge this, please look at 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 position where Chairman Wei Sihua's Mercedes-Benz vehicle stays belongs to the inner side of the parking lot, except for the south exit, and then there is a very inconspicuous exit on the root road of the rear wall. According to the comrades of the security department of the city's First People's Hospital, this small exit is a special exit for transporting medical waste from the hospital, and it is hardly locked in normal times. After walking out of this exit, there is a small remote alley outside, and you have to zigzag around more than 200 meters to get to Qingquan Road......" Speaking of this, Shi Dongming paused, "If it weren't for the locals who are very familiar with the city's First People's Hospital, they wouldn't know that there was this exit." ”

"According to the analysis of the suspects in the theft of smashing car window glass, when they choose the target of the theft, they will first observe the way out, in case the theft is found to be blocked inside and unable to escape." Shi Dongming continued, "Therefore, if it is a crime committed by a wanderer, it will not choose the vehicle near the location where Chairman Wei Sihua is parked as the target of the theft, because it seems that there is only one exit, and it is easy to be blocked inside." ”

"And according to the information on the car smashing and theft cases that have been detected, most of the locations where the smugglers committed the crime were near bus stations and railway stations, so that they could quickly flee to other places when committing the crime." Shi Dongming turned another page, and the screen showed a projection of a page of information, "In a place like the First People's Hospital of the city, which is far away from the bus station and railway station, there has never been a case of smashing and stealing cars by wanderers. Therefore, I recommend that DNA collection start with our local habitual thieves in Maple Grove. ”

"Even if you start collecting DNA samples from our local habitual thieves in Maple Grove City, it's a very large number!" Jiang Fangchang pondered for a moment and said, "According to the information I have at hand, there are four hundred habitual thieves who have registered in our Fenglin City police system, and if the DNA samples of these people have to be collected and tested, whether it is the cost of time or the capital cost of technical testing, it is an extremely large amount of data!" ”

Bao Feiyang nodded, Jiang Fangchang's concerns were not unreasonable. If the DNA of these more than 400 habitual thieves is tested, it is said that it is the cost of capital, according to the cost of testing the DNA of a criminal suspect of 3,000 yuan, it will require more than one million yuan of funds, which is undoubtedly an extremely large capital expenditure for the Fenglin City Police Department, which is not too rich in funds!
