Due to professional habits, Li Yi entered the study room next to the living room.

The study room was neat and tidy, and the Lucky Cat on the desk was shaking its paws rhythmically. Under the slanting light, there were still a few old fingerprint marks on the desk.

"There are fingerprints." Li Yi pointed to the table.

"It has been collected and compared by the technical team. It is Zhu Xing's fingerprint. This study is probably only used when Zhu Xing comes back. Look at this room. There are a few books scattered on the bookshelves.

There is more wine than there is in the wine cabinet outside.”

"Wine is a catalyst. In addition to catalyzing things between men and women, it can also catalyze the beating of thoughts in a certain aspect of the brain. I think it's okay. Sipping wine and reading a book can be regarded as a kind of mood."

"The valuables in the house are not missing. In fact, nothing is missing." Qin Gang said.

Li Yi nodded, "The thief woke up Ms. Lin unexpectedly. It happened in a hurry. There was no time and no chance to find any more items. Otherwise, I could always find a wallet. I don't have much cash, but I always have bank cards, and

I believe Ms. Lin has more than one card in her wallet. Go out and find a teller machine, put the card in and try the password at will. Such passwords as 123456 or six ones do not look like passwords. Many people set their bank card passwords like this.

Including my old father. Even if he makes a mistake and gets eaten, it doesn’t matter."

"It would be good to be able to run away. In this case, you have to either subdue the victim or get out of the way. If you still want to follow things, you are asking for arrest. Besides, the most valuable gold and silver jewelry are all in the cabinet."

Li Yi pointed to the couplet on the wall signed by Youren, "If this couplet is genuine, the price on the market will be six figures. If it can go to the auction house and someone hypes it up, seven figures is not impossible."

. If I were a thief, I would just come in and get away with this, it would save me a lot of trouble, it would be easy and I could steal the treasure quietly."

Qin Gang sighed, "It's not a waste of time to read, become literate, and grow in culture. Our parents have educated us since childhood."

"If that guy could know the value of this couplet, he wouldn't be reduced to being a thief. He wouldn't have to go into the bedroom, just go into the study and roll up the couplet and leave. There wouldn't be any subsequent murders, injuries, thefts, etc.

Injuring someone with a weapon are two different crimes, and the penalties are also very different."

However, Li Yi knew in his heart that compared to a thief, cash is the most practical and effective.

Precious gold and silver jewelry and other items are small and easy to carry. They can be carried in any pocket on the body. There is no need to prepare a bag specially for thieves. It is not troublesome or trivial to get rid of them. It can be regarded as the second choice for burglary.

Although jewelry and diamonds are valuable, you need to know the goods first and have special channels to sell them. Otherwise, the goods will not be sold and cannot be cashed in. However, it is still a second choice, and it is easy to carry after all.

Artworks such as antiques, calligraphy and paintings are on a higher level. Firstly, they are inconvenient to carry. Secondly, few people will receive the goods in private. It is basically impossible for ordinary thieves to get through formal channels or auction houses.

Usually it is not within the scope of consideration of thieves.

Cash is the first choice. It can be used without any trace. There is no need to worry about being exposed or leaving any traces. Therefore, no matter what, thieves will enter the room to search. Judging from a common sense of a thief, cash will usually be placed in the bedroom.

From the bedside table, it can be determined that the culprit is an ordinary thief who took advantage of the high wind and dark moon to randomly find a house to prey on the autumn breeze.

However, in this era of prosperous Internet, there are not many families who can put a thousand yuan in cash at home.

"I think this thief is not very well-educated. Although he commits crimes continuously, his methods are not clever. He is just a brave thief, but his brain has not kept up with the development of modern civilization." Li Yi said.

"Why is it that just because he kept this couplet with at least six digits in it and didn't steal it, he spent so much time rummaging through the boxes in the room? And he accidentally woke up the victim, and the theft turned into hurting, and the crime was increased?

Qin Gang asked.

"Do you still remember the security video on the Lakeside Greenway?" Li Yi asked Qin Gang.

"Remember, that guy climbed the wall and showed his true face, and the entire running process was filmed. Did you see anything unusual?"

"It's not an anomaly, it's a detail. Think about the details of his escape."

Qin Gang stared at Li Yi with confusion in his eyes.

"When you saw that guy running away in the video, did he take anything with him? For example, he was carrying a bag or carrying a bag."

Qin Gang thought for a moment and said, "No, my hands are empty."

"Yes, there is nothing on hand, including the murder knife, and there are no accessories such as backpacks or bags to store dirt. Combined with the previous cases, although there is no video of the previous few cases, we can make some inferences."

Li Yi sat down, opened his notebook, and wrote:

Crime tools, knife, rope, and bags to store dirt.

"The knife did not appear in the previous four cases because the victim was having a heart-to-heart talk with Zhou Gong and had no idea that a thief had entered. The thief left easily after committing the crime. But this time, it was because he woke up the victim and in order to intimidate and threaten him.

The victim in uniform showed the murder weapon, but it had no effect. The rope appeared in every case. The thief needed to use the rope to slide down the victim's balcony from the rooftop. After committing the crime, he slipped away from the main entrance, so he always left it behind.

This tool, but the rope is not the climbing rope we see in professional outdoor stores, so it is not easy to trace the rope back to the suspect, which is why this type of case occurs repeatedly."

Li Yi looked at Qin Gang, hoping that his words had struck a chord in Qin Gang's head, but Qin Gang still didn't respond.

"In addition to a small amount of cash, what was lost in the previous four times were mobile phones and laptops." Li Yi pointed to the laptop on the table, "This 15-inch screen is only that big. In the previous cases in the report,

The lost laptops all have 14-inch screens, four out of five." Li Yi gestured with his hands.

"Yes, these items are small and can be carried away in your hands, but it is not convenient to climb the wall with things in your hands."

"Just loosen the belt and insert it into your waist."

Li Yi stood up and put the laptop on the table on his waist. "In fact, the rope can also be tied to the body like this. Wear looser clothes and cover it casually. No one will see anything wrong.

"

Qin Gang loosened his belt, inserted his laptop into his waist, and took two steps. He felt a little strange, but other than that, he didn't feel anything wrong.

"I understand, you are trying to say that the guy never brought a backpack or bag, and never thought about putting anything in it. He entered every victim's house with the purpose of cash. He just wanted to take away whatever he could when he left.

, Just go with it. And every time, the rope is left as a crime tool. I think my brain circuit is a little lacking, and I am not a clever thief." Qin Gang realized what Li Yi meant.

This is what Li Yi means. In this era, cash is a scarce commodity. If you really need to keep a large amount of cash at home, you will definitely lock it in a safe.

"It's very possible that he is a wandering criminal. Every time he goes to one place, he hits a few autumn winds, and then changes places."

"Sure?"
