Chapter 484 Half a Pill

This time it turned out to be cell strengthening.

The last reward related to cells was the cell division controllable gene lock. That reward allowed Chen Yan to heal the wound quickly when he was injured.

Of course, that ability has some side effects, that is, Chen Yan is very edible after using it.

This time it turned out to be cell enhancement. From the name, it should increase Chen Yan's defense.

Moreover, compared with the last auditory enhancement, this cell enhancement is likely to be an advanced task reward. After the first enhancement, it is possible to start a second enhancement.

According to Huang Guojun, Wang Xia was managed in strict accordance with relevant regulations and procedures during her detention, and she had no contact with any foreign objects or external personnel.

In other words, Wang Xia's death by suicide can basically eliminate the interference of external factors.

"Team Huang, is Zhang Hui's death scene still preserved?"

Huang Guojun nodded: "The scene is still there. Zhang Hui died on July 12, and we detained Wang Xia after that."

"Because Wang Xia has not cooperated with the interrogation, everything at the scene, except that the body has been autopsyed, is still under lockdown."

"Okay, so... Team Huang, please make a copy of the video of Wang Xia's prison for me last night. I will take a closer look at it when I have time tonight."

"Let's go to the scene where Zhang Hui was killed now."

The scene of Wang Xia's suicide was in the inner cell of the detention center, and her suicide process was evidenced by video footage.

Therefore, Wang Xia's death process is clear, so now we need to find out why she committed suicide.

And whether she was wronged or not.

In other words, the root cause of Wang Xia's suicide was still the case of Zhang Hui's murder.

What's more, the impact of Wang Xia's suicide is indeed very bad.

Not only the Hulu City Detective Team, but also the Provincial Detective Brigade was under great pressure.

A murder suspect in custody actually committed suicide during detention and interrogation, leaving a bloody note on the wall saying "I am wrongly accused and I did not commit murder."

If the news spreads, what will public opinion think?

As soon as Chen Yan left the detention room, the comrades from the Liao Provincial Detective Brigade's Correction Team came over.

Their job is relatively simple, which is to confirm whether Wang Xia was interrogated in any way that did not comply with the rules while in custody.

Such as torture to extract confessions, fatigue interrogation, etc.

Room 301, Unit 1, Building 3, Zijin Garden, is the home of Wang Xia and Zhang Hui. Five years ago, Zhang Hui was killed here and Wang Xia was also captured here.

This unit building has two staircases and five households. Zhang Hui's house is a side house, door-to-door house 305 is also a side house, and houses 302, 303 and 304 are in the middle.

When Chen Yan walked out of the elevator, someone happened to be moving.

"The tenants of 304 are moving today, and the people living in the other three houses finished moving two days ago."

On a floor where a murder occurred, it would be strange if the residents didn't move out if they had the means.

"Have all the residents on this floor... been investigated?"

Huang Guojun nodded: "Although Wang Xia was caught at the scene of the crime, we also visited and investigated the four neighbors."

"On the day of the crime, it was 10:08 pm. Among the four neighbors of Zhang Hui's family, except for 302, who lives next door to his house, there are people in three households."

"The person who reported the crime at the time was a resident of 305. He heard the shouting and came out to watch the commotion over whose couple was quarreling. But he saw the door of room 301 opposite was open, Zhang Hui fell at the door, and Wang Xia was sitting on her knees. In the pool of blood, he still had a sharp knife in his hand."

"Did the other two households hear the sound?"

Huang Guojun nodded: "I heard it too, but they didn't go out. They came out after 305's neighbor reported the incident and got knocked on the door by 305's neighbor."

The person who reported the crime knocked on the neighbor's door... which is consistent with common sense.

However, this person from resident 305 is quite courageous.

What is the average person's first reaction after seeing a murder?

Calling the police?

No!

It's running!

It's a cry for murder!

Definitely not going to check and then call the police, unless the person is brave.

Of course, most of these situations are reactions to emergencies. According to Huang Guojun's description, when the other party came out, Wang Xia was already kneeling in a pool of blood, which meant that the person had been killed.

If the other party is more courageous, there is a certain possibility that he will not run or hide in his house.

It is also normal to call the neighbors out later.

It's not weird to see people killing people.

"Have the residents of 305 also moved out?"

"They moved out the next day. The residents on this floor, except for 301 and 302, 303, 304 and 305 are all renters."

"The house was rented. If something like this happened, of course we would move out immediately."

Turning aside to let the stevedores move the furniture, Chen Yan got out of the elevator and turned left, facing the door of Room 301.

The door was now cordoned off. The detective behind Huang Guojun stepped forward, took out the key and opened the door.

The entrance was stained with blood that had dried to dark brown.

There are obvious scratch marks extending from the doorway to the living room.

As soon as he entered the scene, Chen Yan activated the visual gene lock and the olfactory gene lock.

First of all, in terms of smell, the smell in the whole room was mixed. The smells of dozens of people who had been here before were intertwined, mixed with the still fishy smell of blood.

Five days have passed since the incident, and it has been very difficult to find any clues from the smell.

It's not that Chen Yan can't distinguish these smells, but there are dozens or hundreds of smells intertwined. Who is the murderer?

There was no way to investigate, and of course after the reporter reported the crime, many neighbors came over. The smell of so many strangers made it impossible for Chen Yan to make an effective judgment based on this.

The visual gene lock is also turned on.

Judging from the blood spraying and dripping at the scene, the deceased should have been stabbed next to the coffee table in the living room.

Then he fell to the ground and crawled towards the door, leaving obvious traces of blood friction.

On the insole at the door, there were blood stains left after kneeling on the ground, which should be where Wang Xia was kneeling at that time.

This seems a little strange.

If Wang Xia was the murderer, then she should have stabbed Zhang Hui near the coffee table.

Afterwards, Zhang Hui fell to the ground injured and crawled out.

Since Zhang Hui fell to the ground at that time, it means that he was seriously injured, otherwise he would not have fallen to the ground immediately.

As he crawled, there were bloody footprints following him step by step, until he knelt down at the door.

There is only one possibility: Wang Xia is finishing the attack.

Zhang Hui, who was stabbed near the coffee table, was seriously injured at the time, but it was probably not fatal. He crawled towards the door in search of a chance to survive, while Wang Xia was stabbing him all the way behind.

Until the other party opens the door...

Um?

Huang Guojun said that when the residents of 305 reported the crime, they saw the door of 301 opposite was open, Zhang Hui was lying on the ground, and Wang Xia was kneeling in a pool of blood.

But who opened the door at that time?

Zhang Hui or Wang Xia?

The answer is obvious, it must be Zhang Hui who opens the door.

Because Wang Xia should have been following Zhang Hui to finish the attack, she had no chance of crossing Zhang Hui to open the door.

There was no need for her to open the door.

Why did she open the door to let everyone know that she was killing someone?

However, if Zhang Hui opened the door, why was there no blood on the door handle?

Zhang Hui was stabbed near the coffee table and fell to the ground, crawling all the way to the door. There were not only traces of blood rubbing against the ground, but also bloody fingerprints.

Judging from the size of the palm, it was definitely not Wang Xia's, which meant that Zhang Hui's hand must have been stained with blood at that time.

So why was there no blood on the door handle when he opened the door?

Approaching the door handle, Chen Yan took a closer look and found that there was indeed no blood.

Could it be that this guy is very particular about hygiene and wiped off the blood on his hands before opening the door?

Don't be ridiculous, people are almost dead, do they still have the energy?

"Captain Huang, have you cleaned this doorknob?"

Um?

"No, nothing at the crime scene has been touched. Compared to the day of the crime, nothing has changed."

Chen Yan nodded and continued to observe.

The layout of Zhang Hui's house is three bedrooms and two living rooms. There is a study room on the left side of the living room and two bedrooms on the right side.

The second bedroom is clean and tidy, with basically no signs of use.

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

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

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

This shows that Wang Xia should use these cosmetics regularly.

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

Chen Yan picked up the medicine bottle and looked at the production date on it. It was produced a year and a half ago, and the medicine bottle was unopened. It seemed that it should be a backup medicine.

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

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

Something flashed past the corner of my eye just now...

Many people have an unconscious habit of seeing something they just took a look at, and when they turn around, the image of that look still appears in their minds.

At this moment, Chen Yan's mind was fixed on the scene he had just seen in the drawer of the dressing table.

Turning around, Chen Yan reopened the drawer of the dressing table.

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

"Team Huang, give me a clip."

During the survey process, there are special clamps for clamping small objects.

"OK!"

In a few breaths, Huang Guojun came back and handed a small folder to Chen Yan.

Gently picking up the white medicine in the hollow of the debris, Chen Yan just looked at it, put it under his nose and smelled it.

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

Fluoxetine!

The half pill 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 used for?

Fluoxetine is the most common drug used to treat depression, anorexia, obsessive-compulsive disorder and other diseases.

This drug is a psychotropic prescription drug that cannot be purchased privately. It must be purchased with a doctor's prescription and can only be purchased at a hospital that is qualified to sell it.

This stuff is not even available in some pharmacies.

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

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

"This is……"

The drawers in the dresser were naturally searched during the inspection.

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

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

Only basic information such as fingerprints and blood stains were collected.

For example, although I have looked at the items in the dresser drawer, there is nothing abnormal about them, so no major inspection has been done.

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

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

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

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

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

Open the drawer and really just take a look.

At first, Chen Yan didn't find anything wrong.

Originally, the drawers had been closed, but the half of the potion that he caught at the last glance always made Chen Yan feel uneasy if he didn't look at it.

It can really be said to be an accident.

Moreover, this half tablet of fluoxetine is similar to an ordinary sleeping pill. They are both white. What is the difference?

If Chen Yan hadn't received the drug cognitive map rewarded by the system, he wouldn't have cared about this half tablet, and he wouldn't have been able to tell that it was half a tablet of fluoxetine that could treat depression.

Chen Yan pointed to the evidence bag in Huang Guojun's hand: "This drug is called fluoxetine. It is a kind of antipsychotic drug. It is mainly used for the treatment of depression."

"This drug is a psychotropic prescription drug, and it is strictly controlled. The source can definitely be traced."

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

depression?

Huang Guojun suddenly realized.

If this is the case, a lot of things can be explained.

Even without investigating, Huang Guojun could guess that the person suffering from depression must be Wang Xia.

As for why Wang Xia didn't cooperate with the detectives' interrogation at all after being detained, it turned out that she might be suffering from depression.

So it's really hard to say what her suicide was.

It is also difficult to determine whether the murderer of Zhang Hui is Wang Xia.

What is depression?

Let me tell you the pathogenesis and causes of depression. In fact, the medical community still does not have an exact explanation.

What kind of people are more likely to get this disease, what kind of people are less likely to get this disease, what kind of environment or external factors stimulate them to get this disease, and whether it is hereditary. In fact, now There is no particularly accurate statement.

It is only during long-term medical practice that some inhibitory drugs have been discovered that have relatively good effects on depression.

But there is no particularly direct method that can cure it.

Mild patients can recover in a short time after active treatment, but there is still a possibility of recurrence.

However, it is difficult for severely ill patients to recover and can only be controlled with drugs.

The typical characteristics of depression are reluctance to communicate with others and suicidal tendencies.

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

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

Such as resisting, such as calling the police.

It's not that he doesn't want to, it's that his behavior can't do what he thinks a normal person can do.

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

In other words, she had no way to resist.

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

The second bedroom was clean and had nothing but a bed.

After 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 was a simple and normal decoration, but what caught Chen Yan's attention was the computer keyboard on the desk.

Although Chen Yan is not a computer enthusiast and does not know much about some computer accessories, he often played games when he was in the police academy.

Chen Yan was familiar with some particularly cool computer equipment accessories.

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

A desktop computer that costs at most three to four thousand yuan is equipped with a keyboard that costs nearly ten thousand yuan!

what's the situation?
