Don't pick up your boyfriend at the crime scene

The murder weapon was thrown at the first scene of the crime, and it was thrown into the dirty cesspit after the crime was over? In the process of criminal investigation and solving a case, collecting clues is always a hard job, and it is never strange to dig out feces with your hands Things, as long as someone can pull out the first knife from this cesspit, the rest of the people will continue to collect and search for fear of missing any clues.

When Wei Qichen drove over, he felt that the stench near the scene was overwhelming and thicker.

"Captain Wei." As soon as Chen Lin saw the person, he immediately said, carrying the murder weapon that was already in a plastic bag and still stained with dirt, "Have you found the murder weapon? No place on the hand? No, but fortunately, some blood was found at the junction of the handle and the blade. The colleagues in the forensic department have just done blood extraction. It stands to reason that there should be fingerprints on the handle, but this... ................"

Chen Lin looked at the kitchen knife in the bag in embarrassment, and he said to Wei Qichen, "The little girl in the forensic department just now was vomiting and crying, with red eyes, and told me that it was really impossible? There is no way to deal with it, the handle of the knife is full of excrement , If you don’t wipe it, you can’t extract it, and if you wipe it, the fingerprint will be destroyed.”

Wei Qichen glanced at the bag in Chen Lin's hand. He received a phone call in the morning and left the house in a hurry, so he didn't make it in time for breakfast. His stomach was empty and he felt quite hungry, but now it's good. Just looking at the scene and standing there for a second instantly reduced the hunger by 80.00%.

"It can't be done. I have changed two groups of people to go down. I haven't found anything else. It's just some messy and miscellaneous garbage. I don't know if it belongs to the victim or the murderer. No? There is no investigation value."

Wei Qichen was listening to Chen Lin's report on the situation, when he saw a dirty and smelly man coming out of the toilet built in the slate house.

It looked like he had just crawled out of the cesspit. As soon as he stood still, someone beside him pulled a water pipe to help wash away the filth on his body.

Wei Qichen didn't? He didn't think it was dirty? He didn't think it was smelly. If he himself was in a hurry before, he also jumped down the sewer with Qin An and buried him in the sewage, just to catch a cunning suspect. Dirty and smelly ones are a piece of cake for criminal investigators like them, not to mention exaggeration, even if they just came out of the stinky and bloody crime scene, they gang of old men can hold it by themselves A bucket of instant noodles squatted at the door and began to eat.

Even if you are not hungry or even a little nauseous, you have to do it in order not to affect your work and survival? Eat normally to preserve your energy.

Wei Qichen said to the slightly pale man standing under the sun and being rinsed by the cold water pipe, "I really can't get it? Just bring up everything else. Any messy things in the toilet They are all thrown in, even if we salvage all the things, it may not all have the value of forensic inspection."

The man who climbed out of the pit was still washing his calf with the water pipe. After hearing this, he raised his head and grinned. How can a person who never stops cleaning out this cesspit still take the initiative today? Stop shouting?"

Chen Lin smiled and took a clean towel and went over, "Since Team Wei is calling to stop, why are we so worried? I probably have an idea, so let everyone stop busy and come up."

"Okay, then I'll call everyone to withdraw."

He sped up the flushing action a little more, the man cleaned himself up, and then walked into the crime scene covered in moisture again, calling for other colleagues who were still hanging in the cesspit to come up.

Chen Lin was busy tidying up, when he suddenly saw Wei Qichen waving at him, so he hurried over.

"Captain Wei called me?"

Wei Qichen asked, "This one? Where did you fish out the kitchen knife?"

Chen Lin said, "I was supposed to do the last on-site inspection in the morning, but it turned out that the sun was particularly good today. When a colleague was collecting the remaining broken shoe prints where the victim was squatting, he suddenly noticed the hole. There was something shiny on the head under the seat, and I called someone to come in to look again, only to find that it was a kitchen knife blade that reflected light in the sun, so everyone immediately took off their shoes and jumped off to give the thing to ? Fished it up."

Wei Qichen frowned, "So that means, this kitchen knife was just thrown under the pit where the victim was killed?"

Chen Lin nodded, "No? That's right, Captain Wei, did you find anything else?"

Wei Qichen walked forward? Taking a step forward, he stretched out his finger to the slate room and analyzed, "The murderer and the victim should know each other well. For some reason, the two detoured here to go to the bathroom away from the teaching building. It was Friday, and it is reasonable to say that it is the day when the students return home. If people from outside the school want to sneak in while a large number of students are leaving the school, it shouldn't be too difficult, but there is one thing that is very troublesome. Yes, even if he can sneak in with others, but there is no way to escape the door? The uncle who checked the leave slip will go out in a fair and honest way."

Chen Lin said, "Is there any? Is it possible that someone escaped?"

"Not really? It might be." Wei Qichen denied, "I went to check the school's fence on the day the incident happened. The one that blocked the wires and smashed the glass, outside the fence? It's the restaurant in the town, all around the school. If he went out in a gang, it's impossible to leave no traces? What's more? Immediately after the murder, the murderer threw the murder weapon into the cesspit, if it was someone outside the school, why didn't he take the murder weapon away with him?"

Chen Lin thought for a while, and he said, "Impulsive? Committed a crime, and I was very flustered when I killed someone, so I just threw away the kitchen knife and then ran away?"

"If it was an impulsive crime, would you carry a kitchen knife with you? This is clearly a premeditated murder."

Chen Lin hesitated a little. He tentatively asked, "Captain Wei, do you still suspect that this case was done by the victim's friend?"

Wei Qichen turned around, and while walking outside, he asked Chen Lin, "Did you have any girlfriends when you were in college?"

Chen Lin followed him, and the young boy stretched out his hand to touch his head in embarrassment and said, "I talked about one when I was a sophomore, but everyone was too busy with their studies, and then the contact gradually decreased and ended without a problem. gone."

"But even if we break up, there will always be a period of passionate love."

"Of course there is a period of passionate love." Chen Lin said, "But it didn't last long, maybe only half a year. Anyway, it didn't last until the end of my junior year and we broke up."

Wei Qichen continued to ask him, "If it was the period of passionate love, and your girlfriend was going to the bathroom, and you suddenly walked in, how would she react?"

Chen Lin touched his chin with his hand, "If it's a girl, unless she asks me to go in, if I approach by myself, there is a high probability that she will scream loudly."

"Then what do you think? She will take the initiative? Tell you to come in."

"Did you find it after going to the toilet? Bring paper."

"There was a pack of unopened tissues in the female victim's schoolbag. This cannot be the reason."

"Then... When you want to change the sanitary napkin, you find out that you don't have a sanitary napkin?"

"She's not on her period either."

"This..." Chen Lin didn't know anymore, so he asked Wei Qichen, "What do you think, Captain Wei?"

"When the forensic doctor came out with the autopsy results, I basically ruled out murder. First of all, the female victim was a very typical good girl at school and at home. Studying, going home on weekends to help with the family's business, she has no time or possibility to fall in love with outsiders outside the school, etc. Secondly, the first time Yan Zhao came with me, he had already pointed out that the murderer In the process of entering and getting close to the victim, the victim didn't raise her head, which means that she didn't have any doubts about the fact that the murderer would walk into the women's restroom and get close to her. No? There was no scuffle, and he was killed with a single blow."

Chen Lin asked, "Because the victim didn't look up, do you believe that the murderer is a girl?"

Wei Qichen said with a smile, "Then if you are squatting in the toilet for convenience, and a girl suddenly comes in at this time, note, this girl may be your girlfriend, or your girlfriend, or your colleague, or It may be ordinary women who are pursuing you but you have not promised, if they suddenly walk into the toilet you are using, what will you do?"

"I......" Chen Lin frowned to imagine the scene, "If it was a girl? A friend, I might ask her why she came in, but if it was Female colleagues and other ordinary women, I guess I would have to grab my pants and jump up on the spot."

"That's it? It's a problem. If you want to ask her why she came in, will you definitely raise her head? Will you lower your head and ask her why she came in?"

"Probably not." Chen Lin shook his head.

Wei Qichen asked again, "Then what if I pushed the door open and walked in while you were going to the bathroom?"

Chen Lin said, "Come in as soon as you come in. I can't just fart to welcome you."

"This is the difference between normal people seeing the same sex and seeing the opposite sex when it is convenient for them, so I concluded that the murderer should be a girl and a student in school." Wei Qichen said, "After committing the crime, the murderer threw the murder weapon directly. Go to the toilet, and then return to the dormitory, she pretended that nothing happened, even to confuse our police, so she deliberately released false news that the female victim had an off-campus boyfriend, think about it , if she really has an off-campus boyfriend, everyone is in the same class, a dormitory, and a town, will it really happen? Has anyone seen it, no? No one knows, and even all adjectives must be used. Maybe, it seems, it seems Is it? I just asked a few words by the way, and all the students immediately said, I don’t know, and I just heard it. Do you think such a reaction is really normal?”

Chen Lin finally understood, so he nodded and said, "Captain Wei, are you suspicious of that woman? He is the victim's roommate, right?"

"One of the target suspects."

"Then we want to sign a form to interrogate her?" Chen Lin asked, "And that locked cabinet? Do we need to sign a search warrant to open it?"

"Not in a hurry." Wei Qichen waved his hand, "After all, they are all students, so it's not appropriate to interrogate them alone. You will work hard this afternoon to bring all the girls in their dormitory to the Municipal Bureau for interrogation."

"Yes, Team Wei."

"By the way, what about Qin An? He's been talking about it since yesterday, but he didn't meet someone else on such an important occasion today."

"He's not feeling well today. Should he stay in the Municipal Bureau? Come out."

"It's uncomfortable." Wei Qichen complained, throwing the car keys in his hand and striding outside, "You guys look like just an embroidered pillow. You take care of the aftermath. I'll go back and see if he's gone again." What's wrong."
