The Underworld Detective

I said, "How did you get poisoned? ”

She pointed to her leg and said, "Here's a needle eye. It must have been injected with some kind of poison. Is it suicide? ”

I shook my head: "Don't rush to conclusions. The most taboo thing about autopsies is that they are preconceived. ”

Sun Bingxin stared at me laughing. I asked her why she was laughing. She said: "Brother Song Yang, I think you are mature now, more than a senior forensic doctor! When you told me the story of the Song Tzu case, when I heard it, I knew you must be a great person in the future. ”

I chuckled, "I'm flattered. I've only seen so much. ”

Sun Bingxin said: "What should we do next? Wait for the cops to take the body, autopsy, lab test? ”

This is the normal procedure for forensic doctors, but the work can be done in the field, and I said, "Let you see the Song family is out of school! ”

I took out the heartwood and started listening to the internal organs of the deceased, the internal organs were not very abnormal, and then I put the head of the deceased on the yin and yang pillows, and I listened to the sound of the inside of the skull, and I actually heard the sound of liquid.

I suspected that I had heard wrong, hit the yin and yang pillows repeatedly with my fingers, and finally confirmed that I was right.

I said, "The victim's guts are intact, but there's a lot of fluid in the skull. ”

Wang Dali shouted, “Wow, what's wrong with you? ”

I glanced at him and he buried his head in embarrassment. Sun Bing said in surprise: "Brother Song Yang, can you hear me with a little wooden stick? ”

I said, "I'll explain it to you later, and my conclusion is that it's a neurotoxin that dissolves the brain. ”

“Brain lysis, muscle lysis?” Sun Bing-hearted thought.

Don't tell her, I don't even know what poison it is. I think of the waxed man medication in the Prison Break Mystery. It's said to dissolve the whole body muscles. The deceased is like a waxed man, but the symptoms of the body don't look very similar.

I tried to speculate from other sources that the deceased was naked, wearing only a pair of underpants, with no signs of struggle or aggression. Because there was no sunshine, I couldn't use the coroner's umbrella, so I blew some seagrass ash on the victim, and she had only her own fingerprints on her.

I walked into the lounge and found her clothes thrown on a small bed, and I pulled two of her papers from her clothes, one a student ID and one a cafeteria pass. The deceased's name was Xiaoli, and she was the hard-working, thrifty girl called by the culinary master.

I looked around with hollow eyes and found something under the bed, pulled out an empty syringe bottle, no words on it, and an empty syringe.

I took all this out and showed it to Sun Bingxin. Sun Bingxin asked: “Do you want to bring this back for testing? ”

I said, "Testing also needs a big direction, so let's start with reasoning. ”

Sun Bingxin drew a line: “From the position and perspective of the needle eye, the victim gave herself an intravenous injection. Is it really suicide? ”

I said, "If that's the case, it's too painful. Why don't you pick some poison that will kill you more?" And you see the victim's movements, struggling to open the door, but falling to the ground. One more thing, the buttons on the victim's clothes were torn, and the victim should have taken them off herself, and she was very anxious to take them off, so why? ”

“Did she have a fever?” Sun Bingxin asked.

I picked up my clothes and smelled them. Some poisons make people warm up, some sweat evaporates, but not on them, and I shook my head: "You can rule that out. ”

Sun Bingxin suddenly said: “Show me the medicine bottle. ”

She took the bottle and looked at the light for half a day and said: "Brother Song Yang, there are some black residues! ”

I stunned and suddenly had an idea. I opened my ID and showed Sun Bingxin: “Do you think this girl looks good? ”

“It's pretty, Brother Song Yang, why are you asking?” Sun Bing doubted the way.

"I already know the answer, four words of poison, think about it! ”

Sun Bingxin said: “Are you testing me? Let me think, four words of poison... dinitrophenol? No, the symptoms are different... creatine kinase? But the brain won't dissolve..."

I intend to take Sun Bingxin's exam to see if she is solid enough to learn. In a short time, she has said more than a dozen names of poisons, some of which I do not even know. It seems that she has learned very well in toxicology.

Wang Dali never caught the opportunity to intervene and suddenly said: “Is it the legendary sight of blood sealing the throat! ”

I glanced at him and said, "Where did you see blood? ”

Sun Bingxin suddenly said: “Ah, I'm so stupid, you just reminded me, you asked me if this girl is beautiful! ”

She picked up her ID and looked again and again, excited to say, "Yes, she did! Botulinum! ”

I laughed, "That's right! ”

Wang Dali asked stubbornly, "What is botulinum? ”

Sun Bingxin explained: “Botulinum, as girls know, is a plastic needle. ”

Botulinum can dissolve proteins, precisely because this property is widely used in plastic surgery, but the vast majority of lovers do not know that it is also one of the most poisonous poisons in the world! Formerly used by the military as a biological and chemical weapon, it was expressly prohibited in the Geneva Conventions.

One milligram of botulinum can kill 200 million mice. Botulinum levels used in plastic surgery hospitals are negligible and it is absolutely impossible to reach a lethal dose in humans. Nevertheless, there are still many female stars who suffer facial paralysis or neurospasm as a result of injecting this drug.

Botulinum is an anaerobic bacterium that cannot survive in the air and will die quickly. Gangsun Ice Heart said there was black residue in the bottle, so I thought of it all at once!

The girl bought botulinum presumably to lose her legs and suddenly discovered that her body's muscles were dissolving rapidly after the injection, so she panicked and undressed to check. Botulinum poisoning quickly penetrates the brain, making the whole person unconscious. She couldn't get her clothes on and tried to open the door for help, but fell all the way down and never got up.

Botulinum continues to thrive in her body, dissolving her muscles and brain into a zombie in just half a day!

Sun Bingxin said: “This girl probably has no money at home and wants to be beautiful. She bought herself a botulinum needle from the Internet to fight, and this tragedy happened. It's pathetic! Brother Song Yang, it was just an accident. Am I right? ”

I coldly said, "It wasn't an accident, it was a well-planned murder! ”

“Why?” Sun Bingxin surprised.

I lifted the bottle: “Black residues can be seen with the naked eye, and even black heart merchants cannot put so much botulinum in a bottle of potion unless they deliberately retaliate against society. I think this bottle is likely to have been tampered with. In any case, it's definitely a murder! ”

Sun Bing nodded. “You're right. What are we going to do next? ”

“Protect the scene and wait for the police!” I glanced at the cook who was still in a coma and said to Wang Dali: “Go wake him up, I have to ask him something. ”
