The dusty past of the first criminal investigation department

After the inspection, Bai Yumo stood up and took off his mask and said: "The time of death was around [-] o'clock. There was no soot in the mouth and nose. He died before the explosion. He was shocked by electric shocks before he died, and there are many traces of electric shocks on his body. It may have been frightened before. The cause of death is uncertain and needs to be taken back for investigation."

Bai Yumo stopped a person from the third department and asked him to bring over the wallet he had just found in the pocket of the deceased, and show it to Feng Chen and the others, "The name of the deceased is Liu Qi. Judging from the photo on the ID card, it should be him. I, but I have to wait for the landlord to confirm."

After Bai Yumo finished speaking, he called people to put the body in the body bag together, and went to the living room to wait for the landlord.

After Bai Yumo left, Qin Yang and An Mu rushed over, and Bai Luo repeated what Bai Yumo had just said to them.

Bo Hao picked up a few things that had been burned into black charcoal from the room and threw them together, pointing to the broken chair in the living room and said: "This should be a chair, it's made of solid wood, it's been burned into charcoal, look The bombs are all over the house, and it is estimated that they are very close to the bomb."

"No," Feng Chen squatted on the ground and looked at a few pieces of black charcoal, "The bomb is tied to the chair, including the dead, with scotch tape." , When the deceased was just lifted up, there was still tape on his body.

The dead man tied to a chair, electrocuted, frightened, what does the murderer want to do, revenge?Or torture?

The landlord came, An Mu and Qin Yang went to get information about the deceased, Bai Luo frowned and showed something to Feng Chen.

It was a white paper tube with burnt black marks on the inside, "This should be the tube shell of the ****." Feng Chen said after looking at it.

Bai Luo nodded, "This is homemade. The shell is made of paper layer by layer with a super glue. Now there are no paper shells on the market, because the paper shell is not strong enough to withstand pressure. , easy to absorb moisture, and it is easy to resist explosion after being damp. Therefore, the plastic bags with paper shells are generally homemade. Also, I...may have seen this kind of plastic bags.”

"Have you seen it?" Bo Hao looked at Feng Chen, Xiao Bai seemed very disturbed!

Bai Luo paused and said, "Boss, you should still remember the serial bombings in W City more than half a year ago. At that time, my brother in a dormitory was about to go abroad, and everyone in our dormitory went to give him a farewell party. Only Wang Yihang made a quick appearance. In college, he had the best relationship with the classmate who was going abroad, thinking that he might have something to do, so after dinner, the classmate who was going abroad and I went to his police station to look for him. At that time He was involved in the case, and he didn't tell us too much. I just saw this kind of paper sex on his desk, because the chemical composition was analyzed, and he asked us to help search for it. Glue. But we compared almost all the glues on the market, and none of them matched. Therefore, we guessed that it might be the glue made by the murderer himself. This kind of glue will be very hard after being solidified. I studied the shell for a while, and I was very impressed, this paper shell is very similar to that one, the paper used is white paper, the outside of the paper shell is not damaged, only the inside has burnt black marks."

Feng Chen took the paper shell in his hand and pinched it, and the paper shell was not deformed at all, "This paper shell seems to be strong enough, and it is covered with a layer of glue inside and out, so you don't have to worry about moisture. So it may not be homemade. of."

Bai Luo said: "That's right. Later they found someone to make this kind of glue. The composition is very close, and the cost is very high. It is even higher than the cost of copper pipes. In order to save costs, the most expensive pipe shells on the market are all Blued iron pipe shells, even copper pipes are rarely used, and paper shells are not easy to process. So it should be self-made."

Bo Hao said to Bai Luo: "Then what are you worried about?"

Bai Luo pursed his lips, "That case has been closed, the evidence is solid, the murderer was shot half a year ago."
