Chapter 9 7. No trace

The forensic doctors in the identification department are very efficient, and they are also the busiest people in the police station, working almost 24 hours a day.I heard from Lao Cheng that it is common for those people to eat and sleep next to the bloody remains of severed limbs. Therefore, there is absolutely a scientific basis for saying that the people in the appraisal department are the most nervous people. Compared with the corpse, what Team Wang sent was much more ordinary, such as soil samples, soot, cigarette butts, and a few pieces of plants.If you can find clues like fingerprints on these things, it will help a lot.Especially things such as cigarette butts that are in direct contact with the human body will inhale a small amount of human saliva, thus providing more clues.

Zhuo Yang from the identification department brought news to Team Wang: "No fingerprints were found, and those things are surprisingly clean." Lao Cheng was surprised: "How is it possible!" Team Wang thought for a while and said, "I can't rule out the possibility that they wore gloves. But isn't there even saliva on the cigarette butt?" Zhuo Yang said: "No. He probably used a cigarette holder." Cleanliness, everyone ignores this point, but it is really rare to see people who use cigarette holders even when they smoke. One suspect smoked earthy cigarettes, which burn completely and leave no butts; hopes of finding valuable clues in the butts left by another suspect were also dashed.

Lao Cheng sighed: "People who deal with us are very cautious. They knew that it doesn't matter if they keep those things, so they left things generously." Wang Dui sat blankly, without saying a word. I asked, "No clues were found at the previous scene?" "There were no soot and cigarette butts found at the previous scene, only footprints. The suspect should not have waited long for the target to be hunted in the previous few times. There was hope to obtain fingerprints on Dong Yu's necklace, but the The necklace was bought by Dong Yu at a street stall on the day of the incident, and Dong Yu had passed it on among his friends, so it was covered with all kinds of fingerprints..."

Handling a case is not like watching a detective movie. It is really ideal to see the situation of "discovering evidence with the suspect's fingerprints on it" in the movie.Real case handling is much more difficult than that. Team Wang suddenly spoke up: "Since we can't get more clues, let's first investigate based on the information we have so far. Visit and inquire around the street where Li Xiaomeng disappeared, looking for a tall man and a short man, and a neat and high-end dress. , two people who are dressed plainly and have such different styles will not go unnoticed when they walk together. And judging from the number of cigarette butts they dropped, they went to the street to wait for their prey a long time ago, I don't believe that Li Xiaomeng is the only one walking this street."

I said: "It's getting late now." I also wanted to go back to the dormitory to take a hot bath and go to bed early.By the way, I've been at the police station for so long, and I haven't bothered to arrange a dormitory for me. "The sooner the criminals are caught, the more stable the life of the citizens will be. Work first, rest second. This is the fourth lesson today. You are a newcomer, so there are no hard requirements for you. If you want to go back, go back, the two of us first Let's go." Lao Cheng took the car keys and followed Team Wang out the door.

I followed them out and got into the car with them.
