National Forensic Doctor

"The clue about the gallery is a breakthrough discovery. When the victim's paintings were consigned to the gallery, they must have left a series of relevant information. Most importantly, the gallery should have authenticated the consigned paintings, which would have saved the thief a lot of effort."

"The paintings on consignment may not be authentic. It depends on the gallery. Our domestic galleries will authenticate them but they won't guarantee their authenticity. Some paintings cannot be guaranteed to be authentic."

"What's the point of that thief stealing? What's the point of bringing back a fake painting?"

"A fake painting that can make the gallery ambiguous is also worth a lot of money. The point is, what can thieves steal nowadays? Most people don't keep much money at home, and there are not many valuable household appliances. Only mobile phones are easy to sell, and they are placed by the bed one by one..."

"We like to steal gold jewelry over there."

"Zhang Daqian's paintings can be sold for hundreds of thousands even if they are sold at a 10% discount. They are more cost-effective than stealing jewelry. Gold is okay, but jadeite and Hetian jade cannot be sold at a high price."

"It depends on the grade. Some bracelets are easy to sell. We caught someone through a bracelet last time..."

In the auditorium, people talked about everything except logic and reasoning.

Honestly speaking, there are very few people who still engage in reasoning and Sherlock Holmes these days. If they must do it, they will only give the riddle a nice name when other means don't work.

As for now, just look at how fast Jiang Yuan slides the photos and you will know that the so-called other means are playing a remarkable role.

Seeing this, Liu Jinghui said, "Let's sort out this case. If we analyze it from the positive side, it's actually quite simple. The criminal first stole from the gallery. After stealing some paintings from the gallery, he also stole the gallery's customer list. Then, he used the customer list to select suitable targets."

Liu Jinghui: "In this process, the criminals should be quite special in selecting their targets. As far as we can see now, the criminals have the ability to open locks, but they probably don't have the ability to open safes, so the final targets of theft are all paintings, or at least victims whose paintings are not in the safes."

Liu Jinghui: "How the criminals determined their targets can actually be considered as a direction for investigation..."

At this time, Jiang Yuan stopped flipping through the footprint photos and turned around to say, "The criminal came to take a look once, and then came back to steal again when he thought he could steal it."

"Can it be seen from the footprints?" Liu Jinghui was surprised.

"In two cases, the footprints were relatively clear. You can see that the footprints overlapped. The suspect's footprints were covered by the victim's footprints, and then covered the victim's footprints again." Jiang Yuan finished speaking, and then added: "The criminal entered and exited through the window every time. He was very skilled in opening windows."

"Hey, the suspect went in and out through the window?" This time it was Li Zeming's turn to be surprised. He immediately opened his mobile phone and looked for photos of the window.

Although he was not personally involved in the case, he quickly read the case files after Jiang Yuan mentioned it, and did not see any obvious signs of entering or leaving the room.

"It's in these two cases." Jiang Yuan turned around and whispered to Wang Chuanxing, and then he saw the picture pulled to the front, which was the picture of the window lock taken in the previous case.

Jiang Yuan used the mouse to draw a red circle under the window lock and said, "It's not very obvious. He used an old-fashioned hook to open the lock. He was very careful and opened it slowly and seriously, so there was very little mark left. Moreover, I suspect that after he opened the lock on the first day, he would leave a gap for the second day, which would make it easier for him to enter the room the next day."

"You do it twice every time. Are you really not afraid of trouble?" A criminal policeman sitting below frowned. It was obvious that he had never encountered such a thing.

"Some old-timers like to scout the place and treat it as a drill." Another criminal police officer said, "The first time, look at the layout of the room, calculate the value of the items in the room, and observe the routes of the security and patrol personnel, if there are any. The second time, you can find a suitable time to enter based on the situation of the first time, and then quickly take away the things based on the situation of the last time. It is also convenient to go out with large and small bags on your back."

“So complicated?”

"In the past, people stole a lot of things and stole them carefully. Especially when they were gangs, they would send someone to take a look in advance, and then decide on how many people to send the next day, using bicycles or tricycles. At that time, people loved to steal electrical appliances. Televisions were big and heavy, and one person couldn't move them... There are many benefits to making a trip in advance..."

"In this case, we have previously investigated the people who entered and left the cattle farm before the theft, and it seems that no one matches the footprints at the scene."

"Maybe there were multiple people committing the crime. We can compare them with the people being investigated in other cases." Liu Jinghui listened to their discussion and made a small inference. He looked at Jiang Yuan helplessly and said, "Can you confirm the identity of the suspect?"

Jiang Yuan coughed twice and said, "There are two suspects now."

"Two people?"

"Well, we can confirm the suspect's age and height through the footprints. Combined with the information in the database, we can confirm that one of the male suspects is 50-year-old Li Zaicheng, a cultural relic dealer. Ten years ago, he was sentenced to two years in prison for counterfeiting."

Liu Jinghui smiled "understandingly". Since the identity of one suspect has been confirmed, there is nothing to investigate about the identity of the other one. Whether it is through call records and chat software, or through ticket purchase information, accommodation information, etc., there are not too many ways to investigate a suspect's companions.

The police officers in the auditorium also understood the situation clearly and wrote down their thoughts one after another.

Although we knew that it was very likely that Jiang Yuan would find out the result, the result appeared so suddenly that everyone's enthusiasm dissipated in an instant.

At this time, Jiang Yuan said, "The second suspect's unlocking method is quite special. I checked the database and found a 52-year-old male suspect, Yang Huaizhen, who was released from prison three years ago. He is good at hook unlocking. His unlocking method and characteristics are the same."

Liu Jinghui turned around and said, "No...you are also using two clues to investigate this?"

"It's just something that comes handy." Jiang Yuan, Wei Shiqian sat up straight and called out again: "Wei Shiqian, tell me about your analysis of the surveillance."

"Oh... OK!" Wei Shixun responded quickly, picked up his notebook and started speaking. Although it was useless, it was also an excellent training opportunity.
