It was rare to find that there was no case on Friday afternoon, and when I thought that I could easily spend the weekend, the captain's face changed after receiving a phone call......

"Come over to me, go to the police collectively, go to my house, his grandmother's, my house has been burglarized." The captain answered the phone and came out of his office with a black face and shouted to everyone.

As soon as the captain finished speaking, Xiao Su muttered in a low voice: "This case of home theft seems to be under the control of the police station, not the criminal police team......

As soon as Xiao Su's words fell, the captain's eyes immediately looked at me and Xiao Su, and said as he looked, "Well, what you said makes sense." Then you, you go and cooperate with the work of the police station to help investigate the case, you just go directly to my house. Your sister-in-law is taking notes at home and at the police station. By the way, Xiaomei, you go with you. ”

After the captain finished speaking, I suddenly felt like I was going to be ruined on the weekend, and hurriedly smiled and said, "Boss, I didn't answer, Xiao Su said it himself." ”

The captain didn't pay any attention to my words at all, and pointed to the door and motioned for me and Xiao Su to go out. Out of the office, the captain said to the two of us: "You two come to my house and pay attention to the wedding photos of me and my wife hanging on the wall in my bedroom, if it is still hanging on the wall, you don't need to notify, if you are not on the wall, call me immediately, okay."

On the way to the captain's house after leaving the police station, I stared at Xiao Su and said, "Sister, why do you owe so much?" It seems that this weekend will not be able to rest again. ”

Xiao Su also said with a displeased face: "I'll just tell the truth, shouldn't we be in charge of this matter in the first place, it's obviously a fake public benefit." ”

When the two of us arrived, the captain's house was already investigating the scene with police officers from the district police station, and Xiao Su and I took out our documents to explain our intentions, saying that we were helping to solve the case and began to inquire about the situation.

A police officer who handled the case said: "The informant told us that when she went home, she saw that the house was turned over and messed up, and she immediately reported the case. Although it was turned over, nothing was lost, a mink coat and a small safe were lost. ”

When I was talking to the police handling the case, Xiao Su didn't know what to talk about with the captain's wife. After Xiao Su finished speaking, he saw the captain's wife walk into the bedroom and take down the wedding photo hanging on the wall. I took a look, it turned out that there were more than ten hundred-yuan bills pasted on the back of the wedding photos, it seems that the captain secretly hid private money, and it is estimated that this time it will be confiscated.

Just as I was analyzing the captain's private money, a policeman who handled the case said to me: "I just finished surveying the door lock, there is no trace of damage, it should be technically unlocked, and now there are too many people who can use this skill, and it is estimated that they can't find it." The thief entered the room with gloves and foot covers, leaving no traces. And this is an old building area, and there is no monitoring at all. ”

After listening to the police, Xiao Su and I came to the door to observe the door lock, and I saw that there was a very small amount of liquid flowing out of the keyhole. I dipped my hand in the liquid and said, "This thief should be very old, and he is a habitual thief, and he must have been out of touch with society for a long time, at least seventeen or eight years." Check to see if any of them have recently been released from the Long Prison Prison. ”

After I finished speaking, Xiao Su stared at me and said, "Are you going to write now?" Analyze the portrait? ”

I shook my head and said, "I'm not that good, the soapy water coming out of the keyhole is a very old way of unlocking, and it's almost gone." Cut the soap into small slices and fill the keyhole, and then burn the soap in the keyhole with a lighter after the door is opened, which is not used by thieves nowadays. ”

After listening to my words, the police handling the case said: "I have never heard of this method. ”

I nodded and said, "You're about the same age as me, and you've definitely never seen this method, and I've consulted someone before." This method has been lost more than ten years ago, so I said that this thief must have been out of touch with society for a long time, because in recent years, tin foil lockpicking is easier than his. He must have just been released from the long prison. ”

After hearing this, the police who handled the case immediately went to check the information of the recently released prisoners. Xiao Su and I saw that the captain's family was about the same, so we helped my sister-in-law clean up the house. Now that we have a general direction of investigation, the rest will be handed over to the police station, and Xiao Su and I can rest for a while......

"Eighteen, eighteen, joined the guerrilla ......" was woken up by the sound of a mobile phone on Saturday morning.

"Hey, who's calling early in the morning."

"I, you call Xiao Su immediately, you two come to my side of the police station to let you two help, hurry up."

"Oh, sir, hey, I'll go, I'll take it. I'll go right away. ”

After hanging up the phone, I immediately contacted Xiao Su and went to the police station in charge of the theft of the captain's house yesterday. When we arrived at the police station, we saw that the captain was already waiting for us in the police station. Seeing this, Xiao Su and I couldn't help but laugh in our minds, making up the scene of the captain being beaten by his sister-in-law last night for hiding private money.

The captain glared at us like this and said, "I'll settle accounts with you both later." I asked you to come here today because the upstairs of my house was also stolen in the middle of last night, and the loss was heavy, with 110,000 yuan in cash, about 20,000 yuan in gold and silver jewelry, and a laptop. You two will go up and see if it was the trick that stole my house yesterday. If it really can't be solved here, the two of you will take over the case directly at the scene and take over the management of the criminal police team. ”

After the captain explained, Xiao Su and I immediately followed the police from the police station to the scene of the theft. When I arrived at the scene, the policeman who handled the captain's case yesterday said to me: "Just like yesterday, the door lock has not been broken. But colleague, I touched the keyhole without soapy water. It shouldn't be the same person. ”

I squatted in front of the door while listening to him and observed the door lock, I looked at Xiao Su and said, "Do you have an ear plucker or a small tweezer, borrow it from me." ”

After Xiao Su handed me the ear picker, I carefully put the ear picker into the keyhole and scraped it in the keyhole little by little. After a while, I said to Xiao Su, "Give me a tissue." After I finished speaking, Xiao Su immediately handed me the tissue, and I poured the scraped thing from the ear scoop on the tissue, which was some black powder.

Xiao Su immediately asked me after reading it, "What is this?" ”

I didn't answer her, turned to the police and said, "Report this case to the criminal police team together with yesterday's case, and yesterday's case should be done by one person or the same group." ”

After I finished explaining to the police, I smiled at Xiao Su and said: "This time we met a master, the unlocking methods in these two cases are lost methods, the keyhole is the fuel on the match head, the thief made the fuel on the match head little by little into grinding powder and blew it into the keyhole, and directly lit the lock with fire." ”

Xiao Su looked at me with a puzzled look and said, "Why are you definitely a match head?" ”

I smiled wryly and said, "KClO3, MnO2, and S are the ingredients of match heads, so you can go home and check the books yourself." ”

Xiao Su didn't answer me at all, but said to me with a curious face: "I just found out why you have such a good understanding of locks?" Last time you found out in the jewelry store that there was a problem with the lock. ”

I smiled and replied, "My grandfather used to pick the lock." Let's go, report back to the leader. ”

The long-lost traditional method of unlocking has reappeared. Although this method is more time-consuming than the current technology, the probability of leaving traces for the thief is almost zero, far exceeding the probability that some technologies such as tin foil unlocking will leave fingerprints near the keyhole when unlocking, because in both cases, the thief burned the keyhole with a lighter, which would destroy all the clues that could have left fingerprints on the keyhole part of the unlock. It seems that I have met a master this time......
