Netherworld Investigator Chapter 142: Everything in the world is poison

lnmao.org, the fastest update to the latest chapter of Sin Hunter (Detective of the Underworld)!

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

I smelled the scent of tobacco and alcohol on the deceased, which was probably contaminated in a nightclub. I listened to the internal organs with ossicles. Everything was normal, except that the lungs were a little stiff.

I noticed some burnt yellow marks on the fingers of the deceased, and said: "The deceased smokes a lot, and the fibers in his lungs are hardened!"

Huang Xiaotao nodded: "According to her friends, the deceased was a smoker with 30 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 the principle of listening to bones, and she still found it magical.

I found some stains on the chin and chest of the deceased. I opened the mouth and saw a smell of alcohol. There were traces of gastric acid corrosion on the back of the teeth. It was probably because of vomiting before death, but it is not clear whether it was because of drunkenness or poisoning.

The vomit of the poisoned person is also very important material evidence. When I asked Huang Xiaotao, she said: "The vomit of the deceased has been loaded back, and it is being tested by the technical team, and there is no result yet."

Sun Bingxin praised: "Too professional, I have thought of such details..."

Wang Dali said blankly: "Is it the only one who feels sick?"

We gave him a blank look, and Wang Dali buried his head in shame.

In addition to the smell of alcohol, I also smelled some other odors, and then took a closer look at the nose and mouth of the deceased, and took some nasal residues with cotton swabs, and asked Wang Dali to give it to Xiao Zhou for testing. It was suspected that it was chloroform. .

He was about to leave. I thought of something. I took out a bottle of potion from the bag. There should be a freezer in the laboratory. Let him freeze the potion into small ice cubes. I will use it later.

Sun Bingxin and I put on plastic gloves, cut the clothes of the deceased with scissors, and checked the deceased over and over again. Finally, a needle eye was found on her waist. Judging from the subcutaneous bleeding reaction, it should have been stabbed during her lifetime.

The eye of the needle was most likely left by the murderer's injection of poison, but I'm not sure. I took off my gloves and said to wait a while.

Taking advantage of this time, I asked Huang Xiaotao: "Is the deceased Cheng Yahui's patient?"

Huang Xiaotao nodded: "We found a medical record in the deceased's house. She went to Cheng Yahui to see a doctor three months ago."

Sun Bingxin's eyes widened: "Fight against the wind and commit crimes? This guy is too rampant, aren't you watching him?"

Huang Xiaotao said: "Yes, according to the response of my police officer, Cheng Yahui went to this bar last night. The suspicion of this person is growing. I have asked Wang Yuanchao to take someone to control him. Wait for the corpse to experience I’ll probably bring it back when I’m finished, so go directly to the interrogation room to see him!"

Sun Bing said excitedly: "Can I interrogate prisoners together?"

Huang Xiaotao said: "Okay, but the interrogator's name must be signed on the interrogation record, and then it must be shown to the director for review, are you sure?"

Sun Bingxin was discouraged: "Let's forget it!"

At this moment, Wang Dali pushed the door and said, "Yangzi, it was tested. The deceased's nasal cavity is indeed chloroform!"

I said, "Where is the ice cube I want?"

He took out an ice grid: "The time is a bit short, and the freezing is not too strong."

I read and said: "It's alright!"

I put on my gloves again, picked up a piece of ice, and rubbed it repeatedly near the eye of the needle, only to see the blood vessels under the skin slowly showing up. In addition to the normal red blood vessels, one vein showed a clear purple.

Sun Bingxin exclaimed in surprise: "Wow, what is this that can show blood vessels."

I explained: "The potion made from ephedra."

Sun Bing thought for a while and said: "Ephedrine can shrink blood vessels, a smart way, but why not use alcohol?"

I said: "The principle of alcohol contraction of blood vessels is to quickly evaporate to cool the skin. Is it useful for dead people without body temperature?"

Sun Bingxin smiled with his tongue out: "I'm not good at learning!"

I used ice cubes to wipe down the purple vein. This is the path for the toxin to spread. Finally, it reached the chest and spread there. I said, "This is a poison that enters the lungs. Look The lung stiffness of the deceased was due to excessive smoking, but lung failure. But what kind of medicine? Cyanide, hydrocyanic acid? The signs are wrong... Carbon monoxide, no, that is gas... Castor beans? Not like it. ..."

Sun Bingxin took some blood from the eye of the needle with a cotton swab, and said, "I will get the test next door, Song Yang brother, should we compare the results first!"

I said: "Okay, let's bet on a meal!"

She laughed and said: "Haha, then you wait to invite me to dinner, I will go by first."

Said she took her small suitcase and left, Huang Xiaotao smiled and said: "You have to come on, don't lose to Miss Sun."

I smiled bitterly: "Actually, I'm not so sure this time..."

A drug test is like a liberal arts exam. I don’t know or I don’t know. I can't figure out what kind of poison it is.

But I can’t give up on myself. I checked carefully, including the hidden parts of the dead. Wang Dali vomited: "Why do you look there every time, is it good-looking?"

I said: "Some poisons are diuretic, such as the nitrite tested that day. I thought of it precisely because I saw residual urine under the deceased."

However, this poison has no diuretic function, not only that, there are no obvious signs throughout the body. This made me feel worried. I don't care about winning the bet, but hope that Sun Bingxin can get the result as soon as possible.

At this moment, Sun Bingxin suddenly opened the door and came in, wearing plastic goggles for testing on her forehead, and smelling of chemicals, and exclaimed excitedly: "Big Brother Song Yang, I have checked it out!"

Wang Dali was surprised: "Oh my God, Yoko actually lost!"

I said: "There is a specialization in the surgery industry, I am not good at drug testing, sister Bingxin, tell me the answer!"

She smiled and said: "Three words, guess what!"

I gave a wry smile: "If I could think of it, I wouldn't stay here for a long time."

She shook her head: "You must know that my father and Uncle Wang **** this poison every day."

It suddenly dawned on me: "Nicotine!"

Sun Bingxin clapped his hands and shouted: "That's right, the poison is high concentration of nicotine, the concentration is enough to kill."

I said with emotion: "Smart, so smart!"

Sun Bingxin blushed and said, "Oh, I'm embarrassed to praise me. If you didn't say that it was poison that entered the lungs, and you eliminated so many drugs in one breath, I wouldn't be able to think of it. Go ahead and board first."

"I didn't praise you, I was talking about the murderer!" I replied.

Sun Bingxin's face suddenly became ugly, Huang Xiaotao secretly laughed, and I realized that I had just said this without thinking about it, which exposed my emotional intelligence shortcomings.

However, Sun Bingxin was innocent and lively, and soon returned to normal: "Brother Song Yang, why do you say the murderer is smart?"

I said: "You think, a female white-collar worker has stomach problems, so she poisoned her stomach medicine; female students love plastic surgery, so she uses Botox for hands and feet; the model’s private life is improper, and the poison lies in contraception. Put it on; this deceased is a smoker, so he just kills with nicotine! It is completely poisoning the characteristics of each person, and the deceased is not aware of it. This kind of meticulous thinking is absolutely impossible."

Sun Bingxin said: "Our teacher said that everything in the world is poison. The difference between toxic and non-toxic is only the dosage. Even eating too much salt and sugar in daily life will cause death. The murderer must be very pharmacological. , By doing tricks on the dosage, it will turn botulinum and nicotine into killing poison!"

I glanced at the deceased. If it were not for the needle eye on the waist, it would have become a case where the cause of death could not be found. After all, the deceased had a large amount of nicotine in his lungs.

When I think of this, I feel sorry for the murderer. If the crime method can be more sophisticated, it is almost a perfect crime.
