Start with Psychic Forensics

　　After all, a comprehensive autopsy of the deceased will generally be carried out after the body is brought back to the bureau.

　　It's past three in the morning.

　　After all the necessary things were delivered, Fang Ze asked the others to rest and recuperate, and planned to go to the bamboo house where Li Ruicheng died.

　　Luo Bixin didn't go to sleep, but rubbed hard and followed Fang Ze's side.

　　Fang Ze did not bend her, so he had to agree.

　　At the scene, inside, Fang Ze squatted on the ground, looked at the black corpse in front of him, and slowly exhaled.

　　The corrosion of the corpse by concentrated sulfuric acid undoubtedly caused a lot of obstacles to the autopsy.

　　To get the most accurate results, even Fang Ze needs to be careful and careful.

　　Luo Bixin stood next to Fang Ze, wearing a mask, quietly watching this scene.

　　After a while, Fang Ze took the scalpel and carefully cut open the chest of the deceased, deflecting to the heart.

　　Since it is sudden death, then the problem basically lies here.

　　Fang Ze is now using not only forensic anatomy, but also pathological anatomy knowledge to ensure that the data is foolproof.

　　Zombies have begun to appear at this time, but have not yet spread.

　　Following Fang Ze's movements, a large amount of blood slowly flowed out, but it had not yet completely coagulated.

　　Generally speaking, it takes at least eight hours for the blood in the deceased to fully coagulate.

　　This is also why Fang Ze wanted to conduct an on-site autopsy, he was in a hurry.

　　It is quick to transport equipment from the bureau, but it will definitely take more time to transfer the body back to the bureau.

　　Under the bumps, some small traces may also disappear.

　　Fang Ze must ensure the blood flow to carry out the most accurate cadaver test

　　"There is no visceral breath, indicating that the internal organs of the deceased are intact and not damaged."

　　"The toxicology test was normal, and the deceased was not poisoned."

　　"Severe ischemia and hypoxia near the heart, fibrillation traces in the ventricular fibers, and everything in the precordial area is normal without any pathology. It is absolutely certain that it is cardiac arrest."

　　If it is said that Ming Chuan and Fang Ze broke up before, there is more than [-]% certainty.

　　So now the probability has reached [-]% Li Ruicheng, that is, he died of sudden visceral arrest.

　　Fang Ze put down the scalpel and fell into deep thought.

　　Beside, Luo Bixin said: "Or accidental death"

　　Fang Ze did not speak.

　　If it was an accidental cardiac arrest, then Cen Xue's departure at that time was a big mistake.

　　Cardiac arrest is not a [-]% mortality rate, and if rescue is timely, it is possible to survive.

　　But when consciousness is completely lost, if

　　If rescue is carried out, within a few minutes, it will enter the stage of death, which is almost irreversible.

　　If Cen Xue was there at the time, even a little unprofessional cardiac resuscitation might be effective.

　　Seeing that Fang Ze didn't speak, Luo Bixin continued to ask: "Didn't you say before that there are also artificial methods that can cause sudden cardiac death?"

　　Fang Ze nodded and said: "It is true, but I didn't find any such traces near the heart of the deceased just now."

　　"Then what should I do now, is it possible to determine the accidental death?"

　　At this moment, Fang Ze's brain was working, and various known possibilities flashed.

　　After a while, he turned around and took out a test tube, and dropped a few drops of blood into it.

　　"Refill, give me the copper ion solution."

　　"where"

　　"In the box next to you, with a sticker on it."

　　"it is good."

　　Luo Bixin got up, rummaged for a while in the box Fang Ze said, then took out a small bottle and handed it to Fang Ze.

　　After Fang Ze took it, he picked up a glass bottle and glanced at it.

　　After a pause, Fang Ze took out a little of the liquid in the glass bottle and dropped it into the copper ion solution.

　　Then, he poured all the mixed liquid into the blood of the deceased.

　　Raising the test tube in his hand, Fang Ze looked carefully through the light.

　　One minute, two minutes and five minutes passed, and the color of the blood still did not change.

　　Luo Bixin blinked, stared at the blood for a while, and said, "Is it the wrong direction? I didn't see any changes."

　　But at this moment, Fang Ze's face suddenly became a little dignified.

　　And this kind of solemnity comes from the test tube without any change! After a while, he said slowly: "It is precisely because there is no change that there is a problem!"

　　"what"

　　Luo Bixin didn't quite understand that she was indeed a layman when it came to forensic identification, after all, the criminal police forensic division of labor was different.

　　Almighty police officers like Fang Ze are in the minority after all.

　　The next moment, Fang Ze did not hesitate, took out a new test tube again, and replaced it with new blood from the deceased.

　　He thought of a possibility.

　　"Give me alizarin sulfonate! Stuff, in the kit."

　　Fang Zechong stretched out his hand for the refill, and the speed of his speech increased significantly.

　　Luo Bixin hurriedly got up and brought the reagent box and searched carefully.

　　"Give."

　　Fang Ze took it and put a few drops into a new test tube.

　　"Give me the salt!"

　　"Give."

　　"Lanthanum nitrate!"

　　"Give."

　　Luo refills can be found very quickly, and there are characters on them, so it is not difficult.

　　It's just that she didn't know what Fang Ze found, which caused his complexion to change.

　　Could there be any doubts about Li Ruicheng's death? Fang Ze slowly poured the mixed purple solution into the test tube containing the blood of the deceased, raised it slightly, and checked it through the light.

　　After half a sound, the red-purple color originally formed by the red of the blood and the purple of the mixed solution gradually faded and turned into a crystal clear light pink.

　　Looking at the pink liquid in the test tube, Fang Ze took a deep breath and said, "Refill, this is probably a murder case."

　　"What did you say!"

　　Feilu reminds you: three things to read, collect and push

Chapter 94 The real cause of death [Second]

　　"What did you say!"

　　Luo Bixin opened his mouth in astonishment, the reversal seemed to be a bit fast.

　　Could it be that someone really caused this seemingly unexpected cardiac arrest? Fang Ze's blood test just now, after a brief moment of surprise, Luo Bixin hurriedly asked: "What's wrong with the blood test? Is it because of drug residues? "

　　All she could think of was the possibility of drug residues.

　　This is common in forensic identification.

　　Through the detection of the blood of the deceased, special chemical substances that do not exist in the human body can be found, and then the partial or direct cause of death can be inferred.

　　Fang Ze carefully put away the two tubes of blood after the test, turned his head and said, "If it is the blood drug residue, Mr. Mingchuan will not fail to find it."

　　Hearing this, Luo Bixin thought for a while and nodded.

　　Also, she read Ming Chuan's autopsy report, it was very detailed, it could be said to cover all possibilities.

　　Pathological testing, toxicological testing, chemical testing, etc. are all normal, including blood testing.

　　It reads: The blood of the deceased is normal, and no abnormal substances have been found.

　　If this is the case, then why did Fang Ze say with certainty that Li Ruicheng died of homicide after the re-examination, with a huge doubt in his heart, Luo Bixin looked at Fang Ze, and the meaning of the inquiry in his eyes was obvious.

　　Fang Ze took off his mask and said slowly: "This murderer is not easy, we have to prepare in advance."

　　"How to say"

　　Luo Bixin's face froze.

　　Fang Ze continued: "The blood of the deceased is indeed normal, and there is no problem."

　　"In other words, there are no suspicious drugs, chemicals or even other unusual substances."

　　Luo Bixin listened quietly.

　　"but"

　　Having said this, Fang Ze paused and said, "The murderer used an extremely rare method to decompose a certain type of binary compound that could have been detected into an ionic state, preventing it from continuing to fuse."

　　Fang Ze looked at Luo Refill: "You should know that in the state of ions, nothing abnormal can be detected at all."

　　"ion"

　　Luo Bixin nodded and said, "That's right, those are charged particles. The structure diagram is the same as that of atoms. There is no special method and it is extremely difficult to detect. Especially in forensic science, it is rarely used."

　　Fang Ze's words made her understand the reason.

　　If this is the case, then the murderer's methods are too secretive, and there is almost no possibility of finding out.

　　There is only one reason: there is no way to determine the facts by testing, only by guessing the facts and then verifying them.
