I examined the corpse and determined that the time of death was between nine and ten hours, consistent with the confession of the barmaid.

I smelled the scent of cigarettes and alcohol on the deceased, probably contaminated in the nightclub. I listened to the internal organs with bones, everything was normal, but my lungs were stiff.

I noticed the burnt yellow marks on the deceased's fingers and said, "The deceased usually smokes very hard, and the lung fibers have hardened!"

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

Sun Bingxin was surprised: "Wow, Brother Song Yang, your ears are more sensitive than X-rays, you can hear them."

I explained to her the principle of listening to bones, and she still felt amazing.

I found some stains on the chin and chest of the deceased. When I opened the cavity, there was a smell of alcohol, and the back of the teeth had traces of gastric acid corrosion. I probably had vomited before death, but it was not clear whether it was drunk or poisoned.

The vomit of the poisoned person is also very important evidence. When I asked Huang Xiaotao, she said: "The vomit of the deceased has been loaded back and is being tested by the technical team. No results have been found."

Sun Bingxin praised: "It's too professional, such details are thought of ..."

Wang said vigorously, "Is it just me who feels sick?"

We glared at him in unison, and Wang buried his head with great shame.

In addition to the smell of wine, I also smelled some other smells. I sniffed the nose and nose of the deceased carefully. I took some cotton swabs to collect some nasal residues and asked Wang to give them to Xiaozhou for testing. It was suspected of chloroform.

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

Sun Bingxin and I put on plastic gloves, cut the deceased's clothes with scissors, turned the deceased over and over again, and finally found a needle eye on her waist. Judging from the subcutaneous bleeding reaction, it should have been pierced before birth.

The needle eye is probably left by the murderer's injection of poison, but I'm not sure, I take off my gloves and wait for a while.

During this time, I asked Huang Xiaotao: "Is the deceased a patient of Cheng Yahui?"

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

Sun Bingxin's eyes widened: "The crime is committed? This guy is too crazy, aren't you watching him?"

Huang Xiaotao said: "Yes, according to the response of my police officers, Cheng Yahui went to this bar last night. This person is getting increasingly suspicious. I have asked Wang Yuanchao to take someone to control him. Wait until the corpse experience is complete. Bring it back and go directly to the interrogation room to meet him! "

Sun Bing said excitedly, "Can I also interrogate the prisoner together?"

Huang Xiaotao said: "Okay, but the name of the interrogator should be signed on the interrogation record, and then you should show it to the director. Are you sure?"

Sun Bing was discouraged: "Never mind that!"

At this moment, Wang pushed in the door vigorously and said, "Yangzi, it was found out that the dead man's nasal cavity was indeed chloroform!"

I said, "What about the ice cubes I want?"

He pulled out an ice lattice: "It's a bit short, and it's not too cold."

I looked down and said, "Yes!"

I put on my gloves again, picked up a piece of ice, and rubbed repeatedly around the eye of the needle, only to see the blood vessels under the skin slowly appear. In addition to the ordinary red blood vessels, a vein showed a clear purple color.

Sun Bingxin cried in surprise: "Wow, what is this thing that can make blood vessels appear?"

I explained: "The potion from ephedra."

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

I said, "The principle that alcohol constricts blood vessels is that rapid evaporation cools the skin. Is it useful for dead people who have no body temperature?"

Sun Bingxin smiled out his tongue and said, "I am not good at art!"

I wiped the ice vein along the purple vein. This is the path of the toxin spreading. It finally reached the chest and spread there. I said, "This is a poison that enters the lungs. It seems that the lungs of the dead Partial stiffness is due to excessive smoking but lung failure. But what medicine is it? Cyanide, hydrocyanic acid? The signs are wrong ... carbon monoxide, no, it is a gas ... castor beans? Not like ... "

Sun Bingxin took some blood from the eye of the needle with a cotton swab and said: "I got the test next door, Brother Song Yang, let's get the results first!"

I said, "Okay, bet on a meal!"

She laughed: "Haha, then you wait to invite me to dinner, I'll pass first."

Talking about taking her own small box and leaving, Huang Xiaotao laughed: "You have to cheer, don't lose to Miss Sun."

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

The drug test is like a liberal arts test. I do n’t know but I do n’t know. I ca n’t figure out what kind of poison it is.

But I ca n’t give up on myself. I checked it carefully, including the hidden parts of the deceased, and Wang vigorously said, "Why do you look there every time? Is it good?"

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

However, this poison does not have a diuretic function, and not only that, there are no obvious signs throughout the body. This made me worry. I didn't care about winning the bet. I hope Sun Bingxin's side can produce results as soon as possible.

At this time, Sun Bingxin suddenly pushed in the door, wearing plastic goggles for experiment on his forehead, and a smell of chemicals, exclaimed: "Brother Song Yang, I can check it out!"

Wang vigorously surprised: "Oh my god, Yangzi lost!"

I said, "I have a specialty in surgery. I wasn't good at drug testing. Sister Bingxin, tell me the answer!"

She laughed: "Three words, guess what!"

I smiled bitterly: "I can't stop here for a long time if I can think of it."

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

I suddenly realized: "Nicotine!"

Sun Bingxin clapped his hands and called, "The answer is correct, the poison is high concentration of nicotine, which is enough to kill."

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

Sun Bingxin blushed and said, "Oh, I'm so embarrassed. If it weren't for you saying it was a poison to the lungs, and then I ruled out so many drugs, I wouldn't be able to remember it. "

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

Suddenly Sun Bingxin's face became ugly. Huang Xiaotao covered his mouth and grinned. Then I realized that the words had just been spoken without my brain, and exposed my emotional intelligence shortcomings.

But Sun Bingxin was naive and lively, and soon returned to normal: "Brother Song Yang, why do you say that the killer is smart?"

I said, "You think, if a female white-collar worker has a stomach problem, she poisons her stomach medicine; when a female student loves cosmetic surgery, she makes her hands and feet in botox; if the model's private life is not checked, the poison will be on the condom; The deceased was a smoker, and he simply killed him with nicotine! It was completely poisoned according to the characteristics of each person. The deceased unknowingly said, this kind of meticulous mind is absolutely what anyone can do. "

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 if you eat too much salt and sugar in daily life, you will die. The killer must know the pharmacology very well. If you do something, you can turn botox and nicotine into killing poison! "

I glanced at the deceased. If it weren't for the needle on my waist, I'm afraid it would be a case where the cause of death could not be found. After all, the deceased already had a lot of nicotine in his lungs.

Thinking of it, I feel sorry for the murderer. If the crime can be more sophisticated, it is almost perfect crime.
