　　Luo Bixin nodded: "Exclude the compression of the chest cavity."

　　As for sexual suffocation, the possibility is even lower.

　　It will only happen if both parties are willing, and the body is ill and in a state of semi-suffocation.

　　That way, it won't be broken into pieces.

　　Then, there is only one possibility left.

　　Luo Bixin turned his head and said, "Suffocated"

　　Fang Ze said: "Continue, how?"

　　Luo Bixin pursed his lips and said, "Towels, pillows, bedding, all are possible."

　　After reasoning to this, Luo Bixin shook his head helplessly, and said, "I can't think of it, what suffocation is used in 87?"

　　Fang Ze picked up the photo on Luo Bixin's hand and said, "The autopsy results of the file are here, and the conclusion is suffocation."

　　"As for how he died of suffocation, the Yangcheng police did not give an answer at that time, but I have already thought of it."

　　Luo Bixin asked curiously, "What is it?"

　　Fang Ze pointed to the photo and said: "The mechanism of suffocation is that the mouth and nose are blocked, resulting in the inability to exchange oxygen inside and outside the human body, resulting in death from suffocation and hypoxia."

　　"In general, death by suffocation is a long process."

　　"You often go online, you should know that there are many strange people in the world who can hold their breath for a long time."

　　Luo Bixin nodded and said, "I know, the Guinness World Record is twenty-two minutes and twenty-two seconds."

　　Not breathing for such a long time is indeed very difficult to do.

　　However, there is always a shortage of talented people in this world.

　　Fang Ze said: "Yes, if we want to pass a foreign object and suffocate a person, our first reaction is that it will take a long time."

　　"But the longer the time, the greater the possibility that the victim will wake up. It can be said that [-]% will wake up."

　　"Once the slain wakes up and struggles hard, the expression of death will not be what it is now."

　　The refill of Luo's pen is a little smudged.

　　"Why can't I understand?"

　　"Is it suffocating?"

Chapter 237 The murder process deduced by reasoning [1]

　　Fang Ze said: "Don't worry, let me tell you slowly."

　　"If it's a towel, a pillow or a quilt, you'll find that these murder weapons all have one thing in common."

　　"Common ground"

　　Luo Bixin was puzzled.

　　There is nothing in common that is difficult to achieve. Fang Ze, a fabric product, looked at Luo Refill and chuckled: "The so-called common ground must of course be from a forensic point of view."

　　"These things, at the forensic level, are soft objects."

　　"What is a soft object that can change shape and has poor air permeability."

　　"Generally, suffocation caused by soft objects pressing on the mouth and nose will leave a very obvious pale area near the mouth and nose."

　　"These pale areas are irreversible and difficult to recover."

　　"Even after secondary processing, clues can still be found."

　　"But it's not in the photo."

　　"In addition, these soft objects such as towels, clothes, etc., although the air permeability is poor, they are still breathable."

　　"So, if the murderer wants to use these things to kill people, he must use a lot of strength to press the nose and mouth of the deceased."

　　"At least, there will be scratches."

　　"In severe cases, the nose may be crooked or flattened, and the bridge of the nose may even be broken."

　　"There are bruises and lacerations on the lips, gums and tongue."

　　"There have been cases in the past where the murderer used a towel to suffocate people, causing the deceased's teeth to loosen and fall out."

　　After listening carefully to Fang Ze's words, Luo Bixin felt that she had gained a lot of knowledge.

　　She quickly grabbed the photo from Fang Ze's hand and looked at it again.

　　There are no traces of those symptoms.

　　"It's not suffocation caused by squeezing of soft objects!"

　　"what would that be"

　　Fang Ze said: "I haven't finished speaking yet, the second new question."

　　"That's choking time."

　　"As I said just now, if the suffocation takes too long, the deceased will wake up suddenly from sleep."

　　"At that time, the death of the deceased will be more exaggerated and terrifying. These facts do not match."

　　"So, the suffocation time of the deceased should be relatively short, no more than one minute, which is between thirty and fifty seconds."

　　Luo Bixin was stunned for a moment, and said, "No more than one minute"

　　"No way"

　　"Holding your breath for more than a minute, most people can do it."

　　"Even if the lung capacity is low, it will be very uncomfortable, but it will not be fatal. At most, the lack of oxygen will cause dizziness."

　　Fang Ze smiled and said, "Forensic medicine has a term called total asphyxiation."

　　"Total suffocation"

　　"right."

　　Fang Ze nodded, "In human waiting, if a full-scale suffocation without space is applied, it can be suffocated to death in the shortest time."

　　"And, don't look too much."

　　"Because when the dead have just woken up, they are dead."

　　Luo Bixin seems to be listening to a story.

　　After understanding Fang Ze's meaning, Luo Bixin took a deep breath, "How on earth did the murderer create a comprehensive suffocating environment?"

　　"Is it a high-tech vacuum space"

　　"No no no."

　　Fang Ze waved his hand and said with a smile, "It's not that complicated. It's actually very simple. It only needs one thing to do it."

　　"what"

　　"Plastic sheeting."

　　"

　　Plastic sheeting! It's that simple"

　　"That's right."

　　Fang Ze nodded with a smile, and said, "Plastic cloth, plastic wrap, everything is fine."

　　"While the deceased was in a coma, the murderer put a plastic sheet or plastic wrap over her head and sealed it."

　　"When the deceased has just woken up due to massive hypoxia, he is already dead."

　　"This is also the reason why the deceased died of suffocation, but the face was not exaggerated."

　　Luo Bixin stared blankly at the photo in his hand.

　　She would never have imagined that a simple-sounding method of murder would require such complex and meticulous reasoning.

　　To do this, not only the sharp thinking of criminal police, but also the professional knowledge of forensic medicine is required.

　　Perhaps only Fang Ze can do it alone.

　　Luo Bixin was silent for a while, then said: "That is to say, the murder process is very clear."

　　"The murderer secretly gave Diao Aixin a small amount of sleeping pills."

　　"While Diao Aixin was sleeping, the murderer used plastic wrap or plastic wrap to suffocate her to death."

　　"Then, use a rope to strangle the victim's neck."

　　"Then, dismember Diao Aixin's body, fry it, and throw it in the city."

　　Fang Ze nodded and said, "Well, this is the complete murder process."

　　"As for the streak, whether it is the murderer's anxiety or the purpose of confounding the cause of death, it is still uncertain."

　　"Anyway, the murderer is very calm when he kills. It can be said that everything has been planned since the meeting."

　　"So we have to think that this is a murder case."

　　"It's not random killing, it's not serial killing, there is definitely a reason for Diao Aixin's death."

　　Luo Bixin said: "Diao Aixin, such an introverted girl, was brutally shredded for what reason?"

　　"I really can't imagine."

　　"Could it be rape"

　　Fang Ze shook his head: "No, the remaining organs, there is no trace of sexual assault."

　　Luo Bixin frowned: "That's weird"

　　Fang Ze said: "Everything is speculation now, without any supporting evidence."

　　"If you want to solve this case, there is a long way to go."
