Um?

"No, nothing has been moved at the scene, and nothing has changed compared to the day of the incident."

Chen Yan nodded and continued to observe.

The apartment of Zhang Hui’s house is 3 bedrooms and 2 living rooms. There is a study on the left side of the living room and two bedrooms on the right side.

The second bedroom was clean and tidy, and there were basically no traces of use.

The bedroom is also very clean, with two pots of green plants on the balcony and a dressing table next to the head of the bed.

Walking into the dressing table, Chen Yan picked up a few bottles of cosmetics and looked at it.

None of them are full of bottles. Nearly one-third of the foundation in the makeup box is used, and the production date is three months ago.

This shows that Wang Xia should use these cosmetics frequently.

Putting on gloves, Chen Yan opened the drawer under the dressing table, which contained several boxes of unopened cosmetics and a bottle of sleeping pills.

Chen Yan picked up the medicine bottle and looked at the production date above. It was produced a year and a half ago, and the medicine bottle was not opened, so it seemed that it should be a spare medicine.

In addition to these, there were some miscellaneous items inside. Chen Yan looked at it, closed the drawer casually, and turned around to look at the flower pot on the balcony.

But suddenly, Chen Yan turned around and continued to look at the drawer of the dressing table.

Something that flashed through the corner of your eyes just now...

Many people have an unconscious habit of seeing something that has just been taken, and after turning their heads, the scene of that glance still appears in their minds.

Chen Yan's mind was now frozen in the picture in the dressing table drawer just now.

Turning back, Chen Yan opened the drawer of the dressing table again.

In the innermost debris space, there was half a white drug object that attracted Chen Yan's attention.

"Team Yellow, give me a clip."

During the survey process, narrow objects are clamped and there are special clips.

"OK!"

After a few breaths, Huang Guojun returned and handed a small clip to Chen Yan.

He gently picked up the white medicine in the hollow, and Chen Yan just looked at it and put it under his nose to smell it.

In just a moment, Chen Yan knew what this half of the medicine was.

Fluoxetine!

This half of the drug turned out to be fluoxetine.

What is fluoxetine? It is actually a serotonin inhibitor. Taking this drug can reduce the secretion of a selective serotonin in the body.

What is it for?

Fluoxetine is the most common drug for the treatment of depression, anorexia, obsessive-compulsive disorder and other diseases.

This drug is a mental prescription drug that cannot be purchased privately. It must be prescribed by a doctor and can only be purchased in a fixed hospital with qualifications for sale.

This thing is not even available in some pharmacies.

So, where did the half tablet of fluoxetine come from in Wang Xia’s dressing table drawer and who took it?

Chen Yan put half of the medicine into the evidence bag and handed it to Huang Guojun.

"This is……"

The drawers in the dressing table were naturally searched during investigation.

But it was not recorded in the file. After all, after Zhang Hui was killed, Wang Xia knelt in a pool of blood with a weapon. It was inevitable that Wang Xia was the murderer...

Therefore, on-site investigation and evidence collection are not as comprehensive as other evidence sites.

It only collected basic information such as fingerprints and blood stains.

Like the things in the dressing table drawer, although I have seen them, there is nothing unusual, so I have never done a key inspection.

Huang Guojun naturally didn't notice this half of the potion.

Therefore, Huang Guojun didn't understand why Chen Yan took out the half of the potion, and he didn't know what this thing was.

Chen Yan did not blame Huang Guojun and the others for not carefully inspecting the scene.

Just now, the reason why Chen Yan looked through the cosmetics on the dressing table was to determine whether Wang Xia lived in this house for a long time.

Judging from the frequency of cosmetics, it can be confirmed that Wang Xia often uses these cosmetics, which means that Wang Xia often lives in this house.

Open the drawer and just take a look.

At the beginning, Chen Yan didn't find anything wrong.

The drawers were already closed, but the half-piece of the potion I saw at the last glance always made Chen Yan feel worried about not being able to look at it.

It can be said to be an accident.

Moreover, this half of the fluoxetine tablet is similar to ordinary sleeping pills, and they are all white. What's the difference?

If Chen Yan had not received a systematic reward of the drug cognitive map, he would not have cared about this half of the pill, nor could he tell that this was half of the pill that could treat depression.

Chen Yan pointed to the evidence bag in Huang Guojun's hand: "This drug is called fluoxetine, which is a psychostatic drug, mainly used as a treatment for depression."

"This medicine is a prescription medicine for psychiatric drugs, and the control is relatively strict, so the source can definitely be found."

"If this drug appears at home, it means that Wang Xia or Zhang Hui, one of them should be suffering from depression."

depression?

Huang Guojun suddenly realized.

If this is the case, many things can be explained.

Even without investigation, Huang Guojun could guess that Wang Xia must be the one who suffers from depression.

Just talk about why Wang Xia did not cooperate with the interrogation of the investigators after being detained. It turned out that she might have suffered from depression.

So what exactly her suicide was, it is really hard to say now.

There is also the murderer who killed Zhang Hui. It is hard to determine whether it is Wang Xia.

What is depression?

Tell you the pathogenic mechanism of depression, but in fact, there is no definite statement in the medical community.

What kind of people have a high probability of getting this disease, what kind of people have a low probability of getting this disease, what kind of environment or external factors can they get this disease, is it hereditary?

There is no particularly accurate statement.

However, during the long-term medical practice, some inhibitory drugs that have relatively good effects on depression were discovered.

But there is no particularly direct means that can be cured.

Mild patients can recover in a short time after active treatment, but they still have the possibility of recurrence.

However, it is difficult for severe patients to recover and can only rely on drugs to control them.

The typical characteristic of depression is that it is unwilling to communicate with others and has a tendency to commit suicide.

If Wang Xia really suffers from depression, then it is very likely that the person who killed Zhang Hui that day was not Wang Xia.

Because for a patient with depression, even if someone commits a crime in front of him, he is likely to be unable to respond effectively.

For example, resist, call the police.

It’s not that he doesn’t want to, but that his behavior cannot do something that normal people can do if they think in their hearts.

For example, if someone else killed Zhang Hui, then when he handed the knife to Wang Xia after Zhang Hui killed him, Wang Xia might not resist.

Or she has no way to resist.

After leaving the bedroom, Chen Yan walked to the second bedroom.

The second bedroom was very clean and there was nothing but a bed.

Leaving the second bedroom, Chen Yan walked through the living room and entered the study.

A treadmill, a desk, a desktop computer on top, and a bookshelf on the left.

It is a very simple and normal decoration, but what attracts Chen Yan's attention is the computer keyboard on the desk.

Although Chen Yan is not a computer enthusiast and doesn't know much about some computer accessories and equipment, he is also a main player who often plays games when he is in a police academy.

Chen Yan still knows some particularly awesome computer equipment accessories.

For example, the hot air limited edition keyboard on the study desk.

A desktop computer that costs up to three or four thousand yuan actually comes with a keyboard that costs nearly ten thousand yuan!
