I'm in a mental hospital, and a rich and beautiful woman forced me to be her boyfriend

Chapter 123

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

Two bodies were lying on the cold dissection table.

Song Ting had not yet sutured the dissection wound.

From the dissection position, her key investigation area was the heart.

Cardiac arrest.

The problem must be near the heart.

Especially the myocardial fibers.

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

"From head to toe, nothing is left out"

"Unfortunately, no man-made wounds were found."

""Wang Ze, do you think there is something wrong here?"

After the voice fell, everyone looked at Wang Ze.

In the conference room, they can express their opinions on the case as much as they want.

But in the forensic room, it is difficult for them to interrupt, including Li Xiangbin.

After all, everyone has their own expertise.

There are very few people like Wang Ze who are so versatile.

Facing the gaze of the crowd, Wang Ze did not answer Song Ting's words immediately.

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

This was Yan Jiakui's corpse.

From the face, the deceased had a hideous face, his facial muscles contracted, and his pupils dilated.

It was obviously a manifestation of fear.

He must have seen something terrible a few seconds or more before he died.

This point is no longer in doubt.

The point is that a cremator who comes into contact with the dead every day, a person who is almost immune to so-called supernatural events, was scared to death.

It is really strange.

There should be a deeper reason here.

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

The blood has basically coagulated.

But a little liquid blood can still be seen.

"Cotton swab."

Wang Ze moved closer and stared at the wound near the heart.

At the same time, he stretched out his hand.

Upon hearing this, the forensic doctor on the side hurriedly stepped forward and handed Wang Ze a cotton swab.

Wang Ze took the cotton swab and carefully took a little blood sample near the myocardial fibers.

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

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

"Moreover, there was no injection wound near the heart of the deceased."

"Even if someone did something, it shouldn't be done this way."

Wang Ze stood up and looked at the blood on the cotton swab from a close distance. He said,"No matter how the murderer did it,"

"Let's assume that there is something wrong with the blood."

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

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

"However, after decomposition, the compound will become ions"

"According to the hypothesis, how can we determine what the murderer used?"

Wang Ze turned to the test bench and said,"That depends on our luck."

"According to the periodic table, start with the most likely one and check one by one."

""Hey, bring concentrated hydrochloric acid and dilute it to 100 ml.""

Forensic doctor:"Okay.""

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

Forensic doctor:"Okay."

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

Without saying a word, she waited quietly.

Although Li Xiangbin and others could not understand, they knew that they could not be disturbed at this moment, so they stood there quietly.

The whole forensic room was left with the busy sounds of Wang Ze and the forensic doctor.

An hour later.

Wang Ze connected the electrode.

The value came out.

Song Ting hurried forward

"This conductivity……"

"Fluoride ions?"

She knew.

Wang Ze used a simplified version of ion chromatography.

It can accurately detect the presence of specific ions in a short period of time.

But this requires a prerequisite.

That is, you must know in advance what the ions being detected are. (To read the novels of Bao Shuang, go to Feilu Novel Network!)

In other words,

Wang Ze first detected fluoride ions.

"It seems that our assumption is correct, and we are lucky."

Wang Ze took off his gloves and said.

Song Ting was a little surprised by this result.

She was not surprised by the test results.

But Wang Ze's judgment

"How do you know it's fluoride?"

Song Ting asked.

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

"Can cause a person to suddenly suffer a cardiac arrest without leaving any trace"

"At present, there is only one possibility."

At this time, Li Xiangbin couldn't help but said,"What do you mean?"

"Have you determined the cause of death?"

Wang Xiaotong and the others also looked at Wang Ze with curiosity.

Wang Ze turned around and said,"Hydrogen fluoride"

"Hydrogen fluoride is an inorganic compound"

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

Li Xiangbin was stunned:"Gas?"

"What do you mean? The deceased inhaled poisonous gas 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"

"Focus on hydrofluoric acid"

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

"Especially bones"

"Why bones? Because the toxicity of hydrofluoric acid is mainly to attack calcium ions and form insoluble calcium fluoride."

"Specific clinical response, including rapid decrease in serum calcium"

"Thus, it can cause arrhythmia and even... cardiac arrest."

After hearing Wang Ze's words, Li Xiangbin and others' faces changed.

They probably understood.

But the most noticeable thing was the last four words.

Cardiac arrest.

"Was the deceased really 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 else to say.

Wang Ze said:"It was poisoned, but not orally."

"The murderer clearly knew the toxicity and effects of hydrofluoric acid."

"Oral administration will not result in 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 may not actually kill you."

"However, if at this time, a strong external stimulus is applied to the person being injected, causing the blood flow to speed up and impact the ventricle,"

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

Li Xiangbin's eyes widened.

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

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

Li Xiangbin spoke subconsciously.

It would be fine if he was the one to investigate the case.

I didn't expect that he would have to do the autopsy.

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

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

Putting aside the case, it seems like he is destroying the forensic department.

Didn't you see that those forensic doctors were already confused?

Song Ting was better.
