I, Naruto, become stronger with critical hits

Chapter 123

Li Xiangbin, Song Ting and others came to the forensic office.

Two corpses, lying on the cold dissecting table.

Song Ting has not yet sutured the dissecting wound.

From the perspective of anatomical position, her key part of investigation is the heart.

Cardiac arrest.

The problem must be near the heart.

Especially heart muscle fibers.

Song Ting said: "In the past two days, our forensic department has conducted a comprehensive investigation of the two corpses. "

"From head to toe, nothing is missing."

"Unfortunately, no human wounds have been found."

"Wang Ze, do you think there's anything wrong here?"

The words fell, and everyone looked at Wang Ze together.

In the meeting room, they can express their opinions on the case to their heart's content.

But in the forensic office.

It's hard for them to interject.

Including Li Xiangbin.

After all, there is a specialization in the art industry.

There are very few people like Wang Ze who are in full bloom, very few, almost none.

Facing everyone's eyes, Wang Ze did not immediately answer Song Ting's words.

Instead, he circled around one of the corpses a few times.

This is Yan Jiakui's body.

Judging from his face, the deceased's face was hideous, his facial muscles contracted, and his pupils dilated.

Obvious post-frightening performance.

A few seconds or more before he died, he must have seen something terrible.

This.

Now there is no doubt about it.

That's the point.

A cremation chemical company that comes into contact with dead people every day.

A person who is almost immune to so-called paranormal events.

Scared to death.

It's really weird.

There should be a deeper reason for this.

After observing and thinking for a while, Wang Ze put on gloves and gently opened the dissecting wound.

The blood has largely clotted.

But a little bit of liquid blood can still be seen.

"Cotton swabs."

Wang Ze leaned closer and stared at the heart of the wound.

At the same time, reach out.

When the forensic doctor on the side heard this, he hurriedly stepped forward and handed Wang Ze a cotton swab.

Wang Ze took the cotton swab and carefully took a blood sample near the heart muscle fibers.

Seeing Wang Ze's movements, Song Ting couldn't help but say, "Do you still want to test for blood drug residues?" "

"We've tested it twice and there is no toxic reaction."

"What's more, there were no injection-type wounds near the deceased's heart."

"Even if someone does it, it shouldn't be this method."

Wang Ze straightened up, looked at the blood on the cotton swab for a closer look, and said, "Regardless of how the murderer did it." "

"Let's assume that there is a problem with the blood."

"There is no poison reaction, so what if it is decomposed?"

Hearing this, Song Ting was stunned: "Decomposition? "

"However, when the compound is decomposed, it becomes an ion."

"If, according to the hypothesis, how do we determine what the murderer used?"

Wang Ze turned around and came to the laboratory table and said, "Then it depends on our luck." "

"According to the periodic table, start with the most probable, and look it up one by one."

"The one who takes concentrated hydrochloric acid and dilutes it to a hundred milliliters."

Medical examiner: "Okay. "

Wang Ze: "Inhibitor solution, add sodium citrate and sodium nitrate. "

Medical examiner: "Okay. "

Looking at Wang Ze's testing process, Song Ting fell into deep thought.

Didn't speak, waited quietly.

Although Li Xiangbin and the others couldn't understand it, they also knew that they couldn't be disturbed at the moment, and they stood there quietly.

In the entire forensic room, only the busy voices of Wang Ze and the forensic doctor remained.

An hour later.

Wang Ze turned on the electrode.

The numerical value is out.

Song Ting hurriedly stepped forward.

"This conductivity..."

"Fluoride ions?"

She knows.

Wang Ze uses a simplified version of ion chromatography.

The presence of specific ions can be accurately detected in a short period of time.

But this requires a premise.

That is, it is necessary to know in advance what the ions to be detected are. (If you read a violent novel, go to Feilu Novel Network!) ）

Other words.

The first thing Wang Ze detected was fluoride ions.

"It seems that our assumptions were correct, and we were lucky."

Wang Ze took off his gloves and spoke.

Song Ting was a little surprised by this result.

It wasn't the test results that surprised her.

It is Wang Ze's judgment.

"How do you know it's fluoride?"

Song Ting said.

Wang Ze: "When I was in the police academy, I happened to read a book of inorganic compounds. "

"It can cause a person to suddenly go into cardiac arrest without a trace."

"At the moment, there's only one possibility."

At this time, Li Xiangbin couldn't help it and said, "What do you mean?" Let's put it bluntly. "

"Is the cause of death determined?"

Wang Xiaotong and the others also looked at Wang Ze with a curious expression.

Wang Ze turned around and said, "Hydrogen fluoride." "

"Hydrogen fluoride is an inorganic compound."

"Under normal conditions, it is a colorless, pungent odor toxic gas with very strong hygroscopicity."

Li Xiangbin was stunned: "Gas? "

"What do you mean? Did the deceased inhale toxic gases before his death? "

Wang Ze shook his head: "I haven't finished yet." "

"This hydrogen fluoride is easily soluble in water and can be infinitely miscible with water to form hydrofluoric acid."

"The point, on hydrofluoric acid."

"When hydrofluoric acid enters the human body, it enters the blood circulation and affects the tissues of the whole body."

"Especially bones."

"Why bones, because the toxicology of hydrofluoric acid mainly attacks calcium ions to form insoluble calcium fluoride."

"Specific clinical responses, including rapid reduction of serum calcium."

"Thus, causing arrhythmias, and even... Cardiac arrest. "

After listening to Wang Ze's words, Li Xiangbin and the others changed their faces.

They probably understand.

But the last four words are the most noticeable.

Cardiac arrest.

"Did the deceased really be poisoned?"

Li Xiangbin was surprised.

Song Ting looked at Wang Ze.

As a senior forensic doctor, she knew that the other party must have something to say.

Wang Ze said: "It's poisoning, but it's not oral." "

"The murderer obviously understands the principle and effect of the toxicity of hydrofluoric acid very well."

"Oral administration, you can't achieve the effect of being scared to death."

"The safest way is to inject fluoride into the blood near the heart to destroy the myocardial fibers."

"Fluoride is not highly toxic, it takes time to react, and it doesn't necessarily really kill."

"But if at this (good time), a strong external stimulus is applied to the injected person, causing the other party's blood flow to increase and hit the ventricles."

"Then, there will be a great probability that people will be scared to death."

Li Xiangbin's eyes widened.

I didn't expect that the truth would be like this.

"Wang Ze, you really provoked the whole case by yourself."

Li Xiangbin subconsciously spoke.

It is up to him to investigate the case.

Unexpectedly, even the autopsy had to be done by him.

If you do this, it will look like the rest of our criminal investigation team is very stupid.

Wang Xiaotong and Bao Qu also looked at Wang Ze with admiration.

Putting aside the case, it's a bit of a suspicion of smashing the forensic department.

Didn't you see those forensic doctors, they were already blinded?

Song Ting is better.
