The Underworld Detective

I checked the body and concluded that the time of death was between nine and ten hours, consistent with the bartender's statement.

I smelled tobacco and alcohol on the deceased, probably contaminated in a nightclub, and I listened to the viscera with bone wood, and everything was fine, just a little stiff in the lungs.

I noticed some scorched yellow marks on the fingers of the deceased, saying: "The deceased smokes pretty good and the lung fibers are hardened! ”

Huang Xiaotao nodded: “According to her friends, the deceased is a smoker with thirty cigarettes a day. ”

Sun Bingxin exclaimed: “Wow, Brother Song Yang, your ears are more sensitive than x-rays, you can hear them all. ”

I explained to her roughly how to hear bone defense, and she still finds it amazing.

I found some stains on the deceased's chin and chest. At first glance, there was a smell of alcohol. There were signs of acid corrosion on the back of his teeth. He probably vomited before he died, but I was not sure if it was alcohol or poisoning.

The vomit from the poisoner is also very important physical evidence, and when I asked Huang Xiao Peach, she said: "The vomit from the deceased has been loaded back and is being tested in the technical group, and the results have not yet been obtained. ”

Sun Bingxin praised: “It's too professional, I think of all the details...”

Wang Dali said quietly: "Am I the only one who feels disgusted? ”

We whispered to him, and Wang buried his head in shame.

In addition to the taste of alcohol, I smelled something else. I smelled it carefully in the mouth and nose area of the deceased. I took some nasal residues from the cotton swab and asked Wang Dali to give it to Zhou for testing. I suspect it was chloroform.

He was just leaving, and I thought of something, and I took a bottle of potion out of the bag, and there was supposed to be a freezer in the lab, and I asked him to freeze the potion into a little ice, and I was going to use it later.

Sun Bingxin and I wore plastic gloves, cut off the victim's clothes with scissors, checked the victim over and over again, and finally found a needle eye in her waist, judging by the subcutaneous bleeding reaction, it should have been stuck in her lifetime.

This needle eye was probably left by the killer's injection, but I'm not sure. I took off my gloves and said wait a minute.

At this time, I asked Huang Xiaotao: "Is the victim Cheng Yahui's patient? ”

Huang Xiaotao nodded: “We found a medical record at the victim's house. Three months ago, she went to see Cheng Yahui. ”

Sun Bingxin glanced at him: "Top wind? Isn't this guy crazy? Aren't you spying on him? ”

Huang Xiaotao said: "Yes, according to the reaction of my officers, Cheng Yahui went to this bar last night, and the suspicion grew. I have asked the Dynasty to take him under control. I'll probably bring the body back after the experience. Meet him directly in the interrogation room! ”

Sun Bing said excitedly: "Can I interrogate the prisoners too? ”

Huang Xiaotao said: "Sure, but the interrogation record needs to sign the name of the interrogator, and then show it to the director. Are you sure? ”

Sun Bingxin was exasperated: “Forget it! ”

Then Wang pushed the door in and said, "Yoko, it's been tested. The victim's nostrils are indeed chloroform! ”

I said, "Where's the ice I want? ”

He took out an ice lattice: “It's a little short, not too cold. ”

I looked at the following: "That's enough! ”

I put on my gloves, picked up a piece of ice, and rubbed it again and again around the needle eye, only to see the blood vessels slowly appearing under my skin, and in addition to the normal red blood vessels, a vein appeared clear purple.

Sun Bing shouted in surprise: "Wow, what is this thing? It can make blood vessels appear. ”

I explained, "Ephedra made the potion. ”

Sun Bingxin thought about it and said: "Ephedrine can constrict blood vessels. It's a smart solution, but why not use alcohol? ”

I said, "The principle of alcohol shrinking blood vessels is that they evaporate quickly to cool the skin down. Is it useful for dead people without a body temperature? ”

Sun Bing's heart spit out his tongue and smiled: “I'm not good at learning! ”

I wiped it with ice all the way down that purple vein, and this is the path through which the toxin spreads, and finally it goes all the way to the chest, where it spreads, and I said, "It's a poison in the lungs, and it seems that the stiffness in the lungs of the deceased is not due to smoking overdose, but to lung failure. But what is it? Cyanide, hydrocyanide? Incorrect sign... carbon monoxide, no, that's gas... castor? It doesn't look like...”

Sun Bingxin took some blood from the needle's eye with a cotton swab and said: “I'll take it to the next room for testing. Brother Song Yang, shall we give the results before anyone else! ”

I said, "Okay, let's have a meal! ”

She laughed: "Ha ha, then wait for me to eat. I'll be there first. ”

As she picked up her suitcase and left, Huang Xiaotao laughed: “You have to work hard, don't lose to Miss Sun. ”

I laughed bitterly: "I'm really not sure this time..."

Testing for poison is like a literature exam. I don't know, I can't think of any poison.

But I couldn't give up on myself. I checked the hidden parts of the deceased. Wang Dali threw up the trough: “Why do you look at it every time? Is it nice? ”

I said, "Some of the poisons are diuretic, like the nitrite that was tested that day, and that's exactly why I thought of it when I saw residual urine underneath the victim. ”

However, this poison has no diuretic function, and not only that, it does not show any obvious signs throughout the body. This makes me sad. I don't care about winning games. I hope Sun Bingxin gets results as soon as possible.

At this time, Sun Bingxin suddenly pushed the door in, wearing plastic goggles for experimentation on his forehead, smelling like a chemical agent, and shouted: “Brother Song Yang, I have tested it! ”

Wang Dali was surprised: “Oh, my God, Yoko lost! ”

I said, "I'm not good at testing poison because I have a specialty in art. Give me an answer, Icy Sister! ”

She laughed: "Three words, guess what! ”

I laughed bitterly: "I thought I wouldn't be here for half a day. ”

She shook her head: "You must know, this poison my dad and Uncle Wang smoke every day. ”

I suddenly realized, "Nicotine! ”

Sun Bingxin clapped his hands and shouted: “Correct, the poison is high concentration of nicotine, enough to kill people. ”

And I was like, "Smart, too smart! ”

Sun Bing-hearted blushed: “Geez, I'm not even embarrassed. If you hadn't said it was poison in my lungs, I wouldn't have remembered it if I didn't take another breath to eliminate so many drugs. It would have been too fast. ”

“I'm not complimenting you. I'm talking about the killer!” I replied.

Sun Bingxin's face suddenly became ugly. Huang Xiaotao covered his mouth and laughed. I only realized that he had just said this without thinking about it and exposed my emotional weakness.

But Sun Bingxin was naive and lively, and soon returned to normal: “Brother Song Yang, why did you say the killer was smart? ”

I said, "You know, the girl with the white collar has a stomach disease, she poisons the stomach pills; the girl student loves plastic surgery, she does hands and feet in botulinum; the model's private life is bad, the poison is on the condom; the victim is a smoker, so she kills with nicotine! It is poisoned entirely against the characteristics of everyone, and the deceased is unaware of it, and this meticulous mind is something that no one can do. ”

Sun Bingxin said: “Our teacher said that everything in the world is poisonous. The difference between toxic and non-poisonous is just the dose. Even if you eat too much salt and sugar in your daily life, you will die. The killer must know a lot about pharmacology. If you make hands and feet on the dose, you will turn botulinum and nicotine into killer poison! ”

I glanced at the deceased, and if it weren't for the needle eye on his waist, it would have been a case where the cause of death could not be found, after all, there would have been a lot of nicotine in his lungs.

To think of it, I feel a little sorry for the murderer, and if the criminal manoeuvres were to be a little older, it would almost be a perfect crime.
