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

The study room is neat and clean, the beckoning cat on the desk is rhythmically shaking its paws, and by the oblique light, there are still a few old fingerprint marks on the desktop.

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

"Collected, the technical team has made a comparison, it is a fingerprint of Zhu Pleasant, this study, it is estimated that it will only be used when Zhu Happy comes back, you look at this room, there are a few books scattered around, and the wine on the bookshelf is more than the wine cabinet outside."

"Wine is a catalyst, in addition to catalyzing the little things between men and women, it can also catalyze the beating of thoughts in a certain aspect of the brain, I think it doesn't hurt, tasting wine and reading a book, it is a mood."

"No valuables were lost in the house, nothing was missing." Qin Gang said.

Li Yi nodded, "The thief unexpectedly woke up Ms. Lin, the matter started in a hurry, there is no time and no chance to go any more items, or the wallet can always be smoothed, there is not much cash but there will always be a bank card, and I believe that Ms. Lin has more than one card in her wallet, go out to find an ATM, put the card in and try the password casually, such as 123456 or six ones that are not like passwords, many people have set bank card passwords like this, including my old father." Even if it's wrong, it doesn't matter if it's swallowed. ”

"It's good to be able to run away, in this case, either subduing the Lord, or pulling out his legs and flashing people, and trying to follow things, is asking for self-defeat. Moreover, the most valuable gold and silver jewelry is in the cupboard. ”

Li Yi pointed to the couplet on the wall that was signed on the right, "This pair of words, if it is genuine, the price in the market is in 6 figures, if it can enter the auction house, someone will hype it, and it is not impossible to have 7 figures." If I were a thief, it would be good if I came in and rolled up this word and left, how much trouble would I save, it would be easy to obtain, and I would steal the treasure quietly. ”

Qin Gang sighed, "Reading and literacy, growing into culture, and our parents have educated us since childhood, it's really not a waste of words." ”

"If the goods can know the value of this couplet, they will not be reduced to being a thief, they don't need to go into the bedroom, they just go into the study and roll the couplets and leave, and there will be no subsequent murder, injury, theft and armed wounding, these are two different crimes, and the punishment is also very different."

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

Valuable gold and silver ornaments and other items, small pieces are easy to carry, any pocket on the body can be fitted, there is no need to prepare a bag for thieves to be dirty, and it is not troublesome and trivial to shoot, which is the second choice for burglary.

Jewelry and diamonds, although the value is expensive, but first of all, you have to know the goods, and you also need to have a special channel to sell dirty, otherwise you can't ship the goods and can't be realized, but it is also a second choice, and it must be easy to carry.

Antique calligraphy and painting such works of art, it is a higher grade, first of all, it is inconvenient to carry, and secondly, few people will receive the goods in private, formal channels or into the auction house, with the ability of ordinary thieves, basically unable to get through, usually will not be in the scope of consideration of thieves.

And cash, is the first choice, can be used without a trace, do not have to worry about dew or leave a trace, so, in any case, the thief will enter the room to search, judging by the common sense of a thief, cash is usually placed in the bedside table in the bedroom, it can be determined that the criminal is an ordinary thief, taking advantage of the high wind and the dark moon, randomly found a family to fight the autumn wind.

It's just that in this era of the prosperity of the Internet, there are not many families who can put 1,000 yuan in cash at home.

"This thief doesn't think the level of education is too high, although he continues to commit crimes, but his methods are not clever, he is purely a thief, but his brain still hasn't kept up with the development of modern civilization." Li Yi said.

"How can you see that he doesn't steal this couplet with at least six figures, but goes to great lengths to rummage through the cabinets in the room? And unexpectedly woke up the victim, stealing turned into hurting, and the crime was added to the crime? Qin Gang asked.

"Do you remember the security video on the lakeside greenway?" Li Yi asked Qin Gang.

"Remember, the thing climbed the wall and showed his face, and the process of running was all filmed, do you see anything abnormal?"

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

Qin Gang stared at Li Yi with no confusion in his eyes.

"Did you bring anything with you when you watched the thing run away in the video? For example, carrying a bag or carrying a bag. ”

Qin Gang thought for a moment, "No, empty-handed." ”

"Yes, there is nothing on hand, including the knife that committed the murder, and there are no accessories such as backpacks or bags to store dirt, combined with the previous cases, although there is no video in the first few times, but you can reason."

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

Knives, ropes, bags for dirt.

"The knife did not appear in the previous 4 cases, because the victim talked to Zhou Gong and did not know that a thief entered, and the thief left easily after committing the crime. And this time, it was because he woke up the victim, and in order to intimidate and threaten and subdue the victim, he showed the murder weapon, but it didn't work. The rope appeared in every case, the thief needed to use the rope to slide down the balcony of the victim from the roof of the roof, and then slip through the main entrance after committing the crime, so this tool was left every time, but the rope was not the climbing rope we saw in the professional outdoor store, so it was not easy to trace the suspect backwards from the rope, which is also the reason why this type of case happened repeatedly. ”

Li Yi looked at Qin Gang, hoping that his words had hit the string in Qin Gang's head, but Qin Gang still didn't react.

"In the first four times, in addition to a little cash, I also lost mobile phones and laptops." Li Yi pointed to the laptop on the table, "This 15-inch screen is so big, and the laptops lost in the previous cases in the report are all 14-inch screens, four-fifths." Li Yi gestured with his hand.

"Yes, these items are small, you can walk with them in your hands, but it's not convenient to climb the wall with things in your hands."

"Just loosen a belt and stick it in your waist."

Li Yi stood up and stuck the laptop on the table on his waist, "Actually, the rope can also be tied to the body like this, wear a loose clothes, cover it casually, no one can see that there is anything wrong." ”

Qin Gang let go of a belt, stuck the laptop in his waist, and took two steps, feeling a little weird, except for some, he didn't feel anything wrong.

"Understand, you mean to say that the goods never brought a backpack or a bag, and he never thought about what to carry, and he went into every household's house with the purpose of cash, but when he left, he took whatever he could with him. And every time I left the rope as a tool for committing crimes, I think the brain circuit is a little indebted, not a witty thief. Qin Gang realized what Li Yi meant.

That's what Li Yi meant, in this era, cash is scarce, and if you really need to put a lot of cash at home, it will definitely be locked in a safe.

"It's likely to be a wandering criminal, fighting a few autumn winds in every place, and then changing places."

"Are you sure?"

"Let's be tentative, until the case is closed, everything is tentative."
