After the technicians finished taking the photos, the two put on gloves and shoe covers and entered the scene. There were eight bunks in the cramped container house. The corpse fell face down on the ground, blood was flowing everywhere, and the smell of blood filled the nasal cavity.
Chen Shi sniffed, smelled a sweet smell, looked around and found an empty bottle under the bedside table.
This is a domestically made carbonated drink. It was emptied. Chen Shi unscrewed the cap and found a strange pattern in the cap. He glanced at the bottle and took it out of the bag where the workers emptied the bottle. Unscrew the same bottles one by one to see.
He handed the bottle cap to Lin Qiupu and said, "Look, what is this?"
Lin Qiupu looked at the light and said, "A black butterfly?"
"There is no prize redemption event for this drink. This bottle cap is suspicious. Could it be a criminal signature left by the murderer."
"A new serial killer has appeared in Long'an City?" Lin Qiupu said, what he didn't want to see the most was such a situation.
Lin Qiupu came out with the drink bottle and asked the worker. One worker said that he bought the drink. He opened it and drank it. He didn't notice any bottle cap. Later, he put it on the table. Maybe the deceased opened it and drank it.
The worker asked scaredly: "Is there poison in the drink?"
"There shouldn't be." Lin Qiupu said.
Chen Shi thought about the drink poisoning case ten years ago. Could this case be done by the murderer's brother back then? Of course, this conjecture is not yet based.
The murderer's tactics were clean and neat, and there was no trace of fighting at the scene. There is a high probability that this time it will be a serial murder.
Lin Qiupu called Chen Shi to the car and asked, "Are you dating my sister?"
"How do you tell?" Chen Shi smiled.
"Can I see her recent changes? I don't know what she likes about you, but this is her freedom!"
"The Schelling team is complete."
"Don't come here. I have something here. Go back and take a look." Lin Qiupu took out an envelope from the car and solemnly handed it to Chen Shi.
Chen Shi was about to take it apart. Lin Qiupu said, "Hey, it's important to handle the case. You can go back and see it again!"
The police officers at the scene visited the surrounding area. There was almost no surveillance video. The janitor said at first that he had been on duty, but only after realizing the seriousness of the murder did he tell the truth. It turned out that he received an unfamiliar call saying his granddaughter I was hit by a car on the way from school and my wife couldn't get through with his mobile phone. So I went to the hospital to check the situation. I walked for about an hour, but it turned out that nothing happened.
Lin Qiupu asked: "Who knows your cell phone number?"
"Just relatives and friends, I have never left it to outsiders."
Chen Shi said: "This time the murderer has great magical powers. The seemingly inadvertent killer has actually arranged everything early."
"I asked you to come, not to praise the murderer."
"I'm not a god. At this point, I'm as clueless as you are."
"I knew I wouldn't call you here!"
"But I think drinks are the key. Go to the nearby canteens and convenience stores to buy all the same drinks."
"Go ahead! I'll look for witnesses again."
Lin Qiupu carried forward the spirit of exhaustiveness, asking all the people around, and adjusting all the surveillance videos that could be adjusted. At the same time, Chen Shi ran all the convenience stores in the nearby streets and bought all of them. For beverages, unscrew and check the caps in turn.
When Chen Shi came back at half past eight, Lin Qiupu was smoking a cigarette depressed, and he knew that there was no progress by looking at his expression.
Chen Shi opened his hand, and there were three bottle caps with butterfly patterns in his hand. He said: "I found them in three convenience stores. I asked the store owner. Their supply channels are all from the same person. The monitoring hasn’t checked. You can Send someone to have a look."
"You mean, people who buy this kind of bottle cap will die?"
"Is it familiar?"
"In the beverage poisoning case ten years ago, this time the murderer upgraded it, making it more difficult and more brutal. Is the murderer Wang Sunxu who wears the name'Zhou Xiao'?"
"At present, it is very possible!"
"Check it!"
Lin Qiupu asked someone to go to these three convenience stores to look for surveillance video. He and Chen Shi found a beverage supplier on this street. The man was an agent. He claimed that he delivered the goods to the nearby convenience stores and supermarkets. Lin Qiupu asked Check his inventory.
The agent brought two people to a small warehouse and opened it to see that there were boxes of beverages. There were probably more than one hundred boxes of carbonated beverages.
Lin Qiupu originally planned to buy it for inspection, but he was stunned when he saw this quantity, and said, "Can you take it apart?"
"That won't work, no one wants to take it apart."
"I'll buy ten boxes and calculate it at the wholesale price!"
"okay!"
The agent moved ten boxes. Lin Qiupu and Chen Shi opened the bottle caps one by one. Soon there were bottle caps piled up at their feet. These bottle caps were normal. Chen Shi said, “It seems that they moved in the store. Hands and feet." As he said, he took a sip from a bottle of drink.
"If you buy this bottle cap, you will die, then you should notify the manufacturer now and ask them to stop shipping to major business points."
"The manufacturer may be too late and should inform all citizens not to buy this drink."
"Okay, let's do it!" Lin Qiupu called immediately.
Chen Shi said, "What about these disassembled drinks?"
"Pour it down, no one drinks it."
"I'll take a few bottles... No, take a box!"
"You are so kind."
After receiving the team, Chen Shi went back first. When he got home, he opened the envelope Lin Qiupu gave him. It was actually a duplicate contract with the words "Precautions for dealing with Dongxue", which listed Lin Dongxue hated to eat. Things you hate to do, things you hate to do, one party’s cheating, Lin Dongxue’s unexpected pregnancy, and other unexpected unexpected situations.
Chen Shi was shocked for ten seconds, is there such a worried brother in the world
At the end of the contract, Chen Shi was required to sign, press his fingerprints, and state that the contract was confidential. Chen Shi crumpled the two pieces of paper into a ball and threw it into the trash can outside.
The next day, Chen Shi rushed to the bureau early, and Lin Dongxue saw him and said, "Is it true? The murder of bottle caps?"
"It's just a guess at the moment, has the case been filed?"
"Team Lin has notified that they will go to the meeting later, and most of the police force in the team has joined the task force."
"Look at what he said at the meeting!"
At the nine o’clock project meeting, Lin Qiupu explained the situation. The next part of the unsuspecting police officers was shocked. Lin Qiupu’s eyes were dark and he should have stayed overnight. He turned off the lights and used the projector to show a few videos.
The video clearly shows a man wearing a black sweater walking into the convenience store and coming to the beverage shelf, slipping something out of his sleeve very quickly and stuffing it into the shelf.
The same content appeared in the three convenience stores where Chen Shi bought the bottle cap. Lin Qiupu said: “The suspect was cunning and did not show his face, but judging from his height and age, it is likely to be Wang Sunxu.”
A policeman raised his hand and asked: "Anyone who buys a bottle cap with a butterfly pattern will be killed. How is the murderer determined?"
