The Metropolitan Police Department, in the corner of the garage on the fourth basement floor, where a white enclosed light truck is now quietly parked. Colleagues from the research institute are conducting identification work around the car, everyone is methodically taking pictures of the truck, extracting fingerprints from the door handles, and only when this is all over is over, they will open the door to conduct further search work inside.

At this moment, Lin Xiuyi was standing behind the Kamiki Ryunosuke Police Department, quietly waiting for the results of the investigation. The fingerprints taken from the door handles and steering wheel of the vehicles will be sent to the fingerprint identification department to compare them with the fingerprints of the deceased in the Minato Pier case kept there.

"Uh......h Woo......" The mobile phone in Lin Xiu's pocket made a vibrating sound, Lin Xiuyi bowed slightly to his colleagues to apologize, and then walked quickly to the corner and connected the phone.

"Moses?"

"Police Department, Miss Chiyo did a fingerprint identification for those advertising leaflets, as you expected, there are indeed the victim's fingerprints on them, but now the work of extracting fingerprints and comparing them has not been completed, I will inform you first!" On the other side of the phone, Hanagata called Lin Xiuyi as soon as he learned the news. Although this result has long been expected by Lin Xiuyi, speculation is always speculation, and all police investigations must always speak with evidence.

Through the investigation of the surrounding environment of the crime scene, Lin Xiuyi has a more vivid understanding of the last continuous indecent assault case. As a result, two questions were formed in his mind. First, why did the suspect appear in that area, where the road conditions are complicated, and even with the help of navigation software, it is not easy to walk from the alley where the crime occurred to the park, but the suspect can easily do it. In addition, the Shenmu Police Department specially arranged for the police officer in charge of that area to identify the photo of the deceased, and the police officer in charge was very sure that this guy was not a resident here. Second, why does the suspect think that it is the ideal place to commit the crime, or why does it have both the principle of comfort and the principle of minimum effort to commit the crime?

Lin Xiuyi finally noticed the advertisements in front of the house. That residential area is the quintessence of Wenjing District, and the market price of almost every house will exceed 100 million. Because it's an upscale neighborhood, it's rare to see noisy izakaya and shops around. Hanagata said that it was secluded and there were no people to be seen. However, for most RB people, they prefer to live in a quiet place.

In this high-end residential area, there are a large number of promotional advertisements, and there are many kinds and patterns. It's easy to surmise that there is a dedicated company responsible for distributing these ads. With such a large residential area and so many advertising leaflets, it is absolutely unreasonable if there is no means of transportation.

Another thing that caught Lin Xiuyi's attention was the time on the advertisement, many of the advertising sheets were products, special promotions for catering, limited-time offers and other content. From the distribution of offer times, it is easy to arrange a chronological order for these advertising sheets. For companies like this, which are responsible for distributing advertisements, Lin Xiu used to work when he was in college, and they asked that they not keep sending advertisements to those residents who did not receive them. Because advertising companies also have to consider their own costs, after all, if this situation occurs, there is a high probability that the residents are going out.

However, the advertisements that appeared at the entrance of two households in the alley where the crime occurred took about a week. If this was done by the suspect, Lin Xiuyi was very sure that the suspect was stepping on the spot, and it was likely that the suspect had plans to burglary.

Lin Xiuyi's speculation basically explains why the suspect appeared there and why he thought it was an ideal place to commit a crime. However, for these speculations to be true, they need the help of evidence.

The fingerprints of the suspect appeared on the advertising sheet, which undoubtedly made Lin Xiuyi's reasoning begin to get closer to the facts. If it can be proved that the car that has been parked in the park for more than a month also has the victim's fingerprints, then it will be much easier to determine the victim's identity.

Just as Lin Xiuyi hung up the phone and was about to go back, the phone began to vibrate again. As soon as Lin Xiu took out his mobile phone, he saw that Miki's name appeared on the caller ID.

"Moses!"

"The police department, it's me, Aizawa and I have already confirmed with the third and fourth victims, and a few days before the incident, they both saw people posting advertisements nearby, but the first and second victims were not impressed......" Miki's words were full of disappointment.

"This is a headache, it seems that the suspect is really not the same person!" Lin Xiuyi said regretfully.

"Police, how did you get the fingerprint comparison there?" Aizawa asked abruptly on the other side of the phone.

"The fingerprints on the advertising paper can already be determined to be the suspect's, and the fingerprints on the truck are still being identified, you guys should come back now, if the results match our speculation, we can breathe a sigh of relief!" Lin Xiuyi put down the phone, and immediately returned to the Shenmu Police Department, and whispered the news from Hanagata and Miki to the Shenmu Police Department.

"It seems that your speculation should be the truth, great, Lin Police Department! But I suggest that you put aside the first two indecent cases for the time being, and fully cooperate with us in solving the case of the pier in the port area. The Shenmu Police Department patted Lin Xiuyi on the shoulder and said with a smile.

"Haha!" Lin Xiuyi replied with a bowed head.

From the car being transported back to the Metropolitan Police Department to the fingerprint extraction for identification, it took most of the day to keep the research busy. Although it was past the end of work, no one left, and they were quietly waiting for the results to be released. If the fingerprints of the victim can be found on this car, then the tedious and tedious work of checking the identity of the victim can be over. It wasn't until about 11 o'clock in the evening that the appraisal on the side of the research institute finally had preliminary results.

"We detected the victim's fingerprints on the door handle on the driver's side and on the steering wheel, which basically confirmed that the car was driven by the deceased before his death. ”

"What about the car, who does the car belong to?" asked the Shenmu Police Department impatiently.

"It belongs to an advertising and printing company in Toknai, and they reported to the Metropolitan Police Department a few weeks ago that they had lost a truck, and judging from the information in the report, it should be the one we found!" replied a colleague in charge of intelligence at the headquarters.

"Do you know the name?" asked the Shenmu Police Department.

"It's Kandagawa Printing Advertising Co., Ltd."
