Tokyo Police

With the full cooperation of the sixth headquarters, we found a total of 22 burglary cases in Bunkyo, Chiyoda, and Minato. A common feature of these cases is that most of the houses that have been burglary have been unoccupied for a considerable period of time, and when the victim finds out that he has been burgled, it has been too long since the incident happened. Forensics. So most of these cases are unsolved. For these cases, the police can only temporarily hang up, and continue to follow up when relevant clues are found in the future.

Lin Xiuyi made a comparison between the places where these cases took place and the area where Kandagawa Printing & Advertising Co., Ltd. advertised. It turned out that, as he had imagined, the stolen homes were all located in the business area where Kandagawa Co., Ltd. advertised.

22 cases of theft, what is the probability of not leaving any evidence? If the probability of a perfect theft happening is one in 30. Then the probability of 22 burglaries leaving no evidence is 1 in 30 to the 22nd power. This probability means that this is unlikely to happen.

So when Lin Xiuyi and his colleagues from the sixth headquarters checked all the evidence in the 22 theft cases. They had no trouble finding a slew of potential incriminating leads.

For example, in a building in Akasaka, a leaflet printed by Kandagawa Co., Ltd. was found at the site of the theft, and this leaflet is now kept in the evidence room of the Metropolitan Police Department. Soon someone took this leaflet and went to the forensics class to apply for fingerprint identification.

For another example, in the courtyard of the robbery site in Koishikawa-cho, several clear footprints were found, and an indistinct mark was found in the middle of the footprints. When the case was just investigated, because the markings were worn out, no forensics and scientific research could give the exact pattern printed on it. Lin Xiuyi, with a brand-new investigation idea, immediately linked the pattern to the shoes distributed by Kandagawa Co., Ltd. The employees of Kandagawa Co., Ltd. travel around all year round, so their shoes are all customized by the company. So it's not surprising that the company's pattern is on the sole.

In addition, clear tire tracks were found outside the Kasuga-cho crime scene, and some climbing shoe prints were left on the walls. These things were originally isolated. Because from a burglary perspective, the locations are very scattered, although each of them occurred in unoccupied houses. But this is not a distinct criminal feature, and few burglars dare to commit theft while someone is in the house. In addition, the items lost at the scene did not have any notable features. In some cases, valuable jewelry in the house was lost, and in some cases, brand-name clothes and bags were lost, and in some cases, the loss was mainly in cash. In short, there is no obvious pattern in these cases, and there are six departments in the Sixth Headquarters responsible for theft cases. Each department has an average of a dozen police officers, and only one or two of them will be responsible for one of the cases.

With so many cases distributed in the hands of so many police officers, it would have been impossible to consolidate these cases if Lin Xiu had not thought about it from the perspective of successive theft cases from the very beginning. Parallel case analysis is the basic skill of criminal police. You must know that Lin Xiu used to be a case-solving expert in the Criminal Police Brigade. The Criminal Police Brigade in China would not divide various cases into such fine detail like the Metropolitan Police Department. Chinese criminal police are all-rounders. Usually, murder, robbery, rape, and even drug-related cases occur in the same jurisdiction. Basically, the same criminal police team is responsible. However, in Tokyo, different divisions are responsible for different cases under the investigation section. Some divisions are specialized in homicide cases, while others are exclusively in charge of robbery cases. Lin Xiuyi's sixth headquarters, Department 2, is specialized in dealing with sexual crimes. It is already a fixed procedure of the Metropolitan Police Department to deal with different types of cases according to the division of labor. But this time, the Shenmu Police Department and the others suffered the loss of the Metropolitan Police Department's fine division of labor.

I saw that 22 cases were found at the sixth headquarters, and many cases were still being screened. The people sent by the Shenmu Police Department felt that one head and two were big, they quietly pulled Lin Xiuyi aside, and asked Lin Xiu in a low voice: "Police Department, there are so many cases, we people can read all of them within 48 hours. The information is good, this…”

"Don't worry, don't you think you found tire and shoe prints just now? Go to Kandagawa Co., Ltd. and detain the car that Hayato Ishihara drove when he was working there, and let the forensics class investigate. The tire marks on the car are worn. If it can be confirmed that these tire marks are indeed consistent with some of the tire marks found in these 22 theft cases, we can continue to detain the suspect Hayato Ishihara for the crime of theft. One is to go to his house, UU read www.uukanshu.com and the place where he used to work to see if there are any shoes he has worn. Bring it back for analysis of shoe prints and footprints, I don’t believe that he will not be able to keep him this time ..." Lin Xiuyi confidently instructed the subordinates of the Shenmu Police Department.

"Haha!" Shenmu's subordinate responded excitedly, and then said goodbye to Lin Xiuyi to collect evidence.

Lin Xiu turned around and walked into the office. A police department serving as the head of the department handed Lin Xiu a cup of coffee and said happily to him, "Mr. Xiu Yi, you have helped us a lot this time. If these 22 cases can be handled in one go, If we detect it, our sixth headquarters will definitely impress Mr. Sato with admiration!"

"There, senior, it's just my luck this time. You usually have so many cases to deal with. If it wasn't to help me, would you have the time and energy to look through so many case files? After all, I I want to thank you all very well! It's all thanks to the help of the seniors, I'm really thankful for causing so much trouble to everyone!" Lin Xiu bowed deeply to all the police officers present.

Now the six departments responsible for theft and search in the sixth department no longer regard the re-examination of the case file as an extra job to help Lin Xiuyi. Instead, they are eager to find a few more similar cases. If these unsolved cases can continue If it was incorporated into the series of robberies by Hayabusa Ishihara and Shinichi Nakamura, it would have saved a lot of things.

An hour later, the original 22 burglaries increased by 4, making a total of 26 cases. These case files are now all placed on a separate table. Lin Xiuyi and the rest of the police department are all around this table. 26 thefts, nearly a thousand pieces of evidence found at the scene. Lin Xiuyi swore that if he couldn't open Hayato Ishihara's mouth, he would eat all the files on this table.
