Lin Qianqiu is the captain of the technical investigation brigade and has an almost persistent obsession with everything related to technical investigation.∞79,︾o＠When Shi Dongming picked up these broken glass in the Mercedes-Benz car and stuffed it into a sealed bag, he had already left the scene and accompanied Wang Xinxin to the Provincial Police Department's Physical Evidence Identification Center to send mosquito corpses. This is not to say that Lin Qianqiu thinks that Wang Xinxin can't do this alone. After all, Wang Xinxin has a father who serves as the deputy director of the Police Department. The Physical Evidence Identification Center of the Police Department must not dare to offend Wang Xinxin easily, the daughter of the director, but doing so violates the usual practice, because

According to convention, key cases like May 27, which are registered, generally require the technical investigation officer of the municipal police station below to send the physical evidence that needs to be identified to the police department. One is to reflect the importance of the municipal police station below to this work, and the second is mainly for the reciprocity of level. If Wang Xinxin is sent alone, the people from the physical evidence appraisal center of the police department will not dare to make things difficult for Wang Xinxin, but Lin Qianqiu will be considered ignorant by the person in charge of the physical evidence appraisal center of the provincial department. If Wang Xinxin leaves the technical investigation brigade in the future, those people from the physical evidence appraisal center of the provincial department will definitely find opportunities to let Lin Qianqiu have a better memory.

It was so complicated. In short, Lin Qianqiu accompanied Wang Xinxin to the provincial department's physical evidence appraisal center after Wang Xinxin took out the mosquito corpse. He didn't know that after he left, Shi Dongming took a few pieces of broken glass in the Mercedes-Benz. He then left Wang Xinxin in the provincial department and hurried back to attend the case seminar, and had no time to communicate with Shi Dongming. At this time, he saw Shi Dongming taking out a few pieces of broken glass, so he was naturally happy to see the hunting and did not care about the order of superiority and inferiority. Without waiting for Jiang Fangchang to talk to Reading, he snatched the plastic self-sealed bag from Shi Dongming, stood next to the window, and studied the broken glass in the self-sealed bag with the help of the bright light outside the window.

Jiang Fangchang and Reading met with a look, and both of them laughed helplessly. Both of them were veterans of criminal investigation. Although they were not professional in technical investigation, their attainments in technical investigation were not low. Seeing Shi Dongming taking out a few pieces of broken glass, their first reaction was naturally to take over the self-sealed bags containing broken glass and study what special places were on these pieces of broken glass for Shi Dongming to pick them up and bring them back. But they did not expect that before their hands were stretched out, Lin Qianqiu had already stood up and snatched the self-sealed bags in Shi Dongming's hand. Their movements were so fast that they were even faster than when they flew to rob the murder weapon in the criminal suspect at the critical moment.

"This guy!" Jiang Fangchang laughed and cursed, and reached out to stuff a cigarette into his mouth.

Reading shrugged his shoulders, held up the teacup with both hands, and looked at Lin Qianqiu with a smile, wanting to see what problems this captain of the technical Investigation Brigade, who was two years older than him, could see from these pieces of broken glass.

"Oh! Such obvious signs have been ignored by our technical reconnaissance brigade! Fortunately, Mr. Shi, you went to the scene again! Otherwise..." Lin Qianqiu only looked at it for a few seconds and saw that the trick was coming. He thrashed his thigh in annoyance.

"I said to Lin Qianqiu, don't just hammer your thighs. If you see something, share it with your comrades!" Jiang Fangchang said.

Lin Qianqiu smiled awkwardly and raised the self-sealed bag in his hand high. "Actually, the characteristics are very obvious. When these pieces of broken glass are pieced together, you can see that there is an irregular circular hole in the middle, which is very similar to the hole left by using a slingshot to shoot steel balls through the car window glass in the video material played by Mr. Shi just now. Obviously Mr. Shi was not wrong in his analysis. This car window glass was shot through by the suspect with steel balls!"

"Is that so? Let's take a look?" Jiang Fangchang had actually guessed the answer, but at this time, he could not help but snatch the self-sealed bag containing a few pieces of broken glass from Jiang Fangchang, and held it in front of him to observe.

"Hey, don't say it, it's true! Director, look!" Jiang Fangchang leaned over and raised his self-sealed bag in front of Bao Feiyang, and pointed his finger at Bao Feiyang.

"Well, it's not bad, I can indeed piece together a small circular hole." Bao Feiyang obviously guessed the answer. He also knew that Jiang Fangchang understood that Jiang Fangchang's move was to please him, so he nodded in appreciation.

Then Reading took the self-sealed bag and observed it for a while, and passed it to the people around him. So the plastic self-sealed bag went around the venue and finally returned to Shi Dongming's hands.

Shi Dongming slowly spit out the bubble gum that had been chewed in his mouth, which had no smell in his mouth, and then put it in the ashtray in front of him. Then he opened his mouth slowly.

"From the reaction of the comrades, they should have recognized that the May 27th theft case is a new type of theft case that uses marbles? There should be no disagreement, right?"

As he said, Shi Dongming slowly swept across the venue. As he said, after seeing the pieces of broken glass he had retrieved from the scene in the plastic self-sealed bag, all the members of the task force had agreed to Shi Dongming's judgment on the suspect's tools for the crime.

"Although everyone has no different opinions on this point, I also want to say that the third reason why I judged that the marble theft case was used in the marble theft method, which was the time of the crime." Shi Dongming stretched out his right hand that had bent his index finger and thumb, and slowly bent his middle finger, "I said before that the parking lot of Fenglin First People's Hospital is relatively large. According to the on-site statistics of the parking lot of the First People's Hospital today, a vehicle in and out occurs in three or four minutes on average. According to the on-duty security guard at the gate of the parking lot, the traffic in and out of the First People's Hospital parking lot is almost the same on weekdays, and at least one vehicle in three or four minutes. The time period for the theft case was on May 27, because it was just a matter of looking at the time of the stolen case.

During the peak of the disease, traffic flow will only be more dense. If you follow the traditional theft method of smashing car window glass with hammers or bricks, even a very skilled veteran will take at least five minutes from the start to get the property in the car to the scene. If you consider avoiding the loud noise when smashing the car window glass by the car owners who go to the parking lot to hear the window period, the suspect's crime time will be extended to at least seven minutes. Obviously, the conditions at that time were not left for the suspect to have such a long crime time. From this point of view, only by using the new theft method of marble theft can the suspect be able to successfully steal property from Chairman Wei of Sihua Group."

All the members of the task force nodded, and it was obvious that Shi Dongming's analysis was impeccable.

"According to the above three points, the crime tool used by the suspects of the 527th century is obviously a new type of criminal tool, a slingshot, that has never appeared in the car smashing and theft case in Fenglin City before." Shi Dongming put down his outstretched hand, "We will discuss the crime tool for the suspects of the 527th theft case. Let's discuss the number of suspects."

Speaking of this, Shi Dongming opened the notebook in his hand, looked down, and looked up at Jiang Fangchang, "According to the previous discussions by our task force, everyone tends to think that the suspect committed the crime alone, right?"

Although Jiang Fangchang did not serve as the leader of the 527 task force at that time, he still kept the closest attention to the task force's handling process. After all, this case was personally confessed by Zhang Zhichao and Mayor Shu Qinghua, two Fenglin City party and government giants. Although Jiang Fangchang had already prepared to evade responsibility with Luo Fengcheng's care, he did not dare to relax his attention to the case itself. At this time, Feng Guobing, the former head of the task force, had left the task force, and Jiang Fangchang, the new leader, naturally had to answer Shi Dongming's question.

"At that time, most of the task force's people did tend to think that the suspect committed the crime alone. After all, the members of the task force did not understand the new method of committing crimes, such as marble theft, and their thinking and consciousness remained on the crime tools used by the suspect were heavy objects such as iron hammers, hammers or bricks. The traditional way of smashing car windows and stealing property in the car was too much noise, and it was more convenient for a single suspect to escape." Jiang Fangchang half-answer answered half-answer.

"This is understandable." Shi Dongming nodded, "But now that the comrades have changed their understanding and have learned that the crime tool used by the suspect is a slingshot, then should we rethink whether the suspect commits the crime alone or a gang?"

There was silence in the venue, and the members of the task force looked at Shi Dongming while thinking.

"What do I think is that there should be two suspects in the 527 theft case." Shi Dongming did not leave much time for the task force members to think, so he continued to tell the story. "One reason was that according to the marble theft case statistics of the new theft case cracked by the Xiguan police, more than 93% of the cases of this new marble theft method were conducted in pairs by two suspects, one looking at the wind and the other committing theft. Another reason was that it was analyzed based on the specific situation of the First Parking Lot in Fenglin City."

Stopped and took a sip of tea, Shi Dongming continued to analyze, "We have said many times before that the traffic flow in Fenglin First People's Hospital is very high and vehicles enter frequently. Therefore, no matter how fast or fast the new criminal method, the criminal suspect must consider the possibility of being knocked out. Arrange a partner who is Wangfeng can easily solve the huge risk of being discovered."

Speaking of this, Shi Dongming turned on the slide projector and put out a photo.

"Comrades, please see, this is a photo taken by Comrade Liu Dapao at the crime scene this morning. Most of you should have been to the crime scene. Now looking at this photo, are there any new discoveries?"

Today is the third update, this is the first update.
