Chapter 485 Recover file

Chen Yan found some clues in Zhang Hui’s house, which are quite valuable.

First, the half tablet of fluoxetine found in the drawer of the dressing table can basically determine that Wang Xia has depression or a history of depression.

Second, there is no blood on the handle of Zhang Hui’s house, which is very strange.

According to the analysis of the traces on the scene, Zhang Hui should have been hit by the knife near the coffee table, and after the knife was hit, he dragged his body and crawled towards the door.

The neighbor who reported the case said that he saw Zhang Hui’s house door open with his own eyes, Zhang Hui lying on the ground, and Wang Xia kneeling in a pool of blood with a sharp knife in his hand.

So, who actually opened the door?

And the expensive computer keyboard in Zhang Hui’s study.

A computer costing 3,000 to 5,000 yuan is equipped with a keyboard that costs nearly 10,000 yuan. Why?

Leaving Zhang Hui’s home, Chen Yan went straight to the Xishan Funeral Home where Zhang Hui’s body was stored.

The autopsy work was completed on the day of the crime. Zhang Hui was weighed three times at the time, one in the abdomen and two in the back.

Huang Guojun handed the photo to Chen Yan: “This is the part of Zhang Hui’s knife. We compared the shape of Zhang Hui’s wound and the sharp knife in Wang Xia’s hand.”

“It is certain that the murder weapon is this sharp knife.”

Then came an autopsy report.

Chen Yan put down the photo and took the autopsy report handed over by Huang Guojun. Chen Yan had no objection to the autopsy results of the Hulu Detective Team.

Zhang Hui’s death has obvious characteristics, and the fatal injury is very easy to judge.

And the murder weapon was at the scene. Just by comparing the depth and width of the knife edge on Zhang Hui’s body and the shape of the sharp knife in Wang Xia’s hand, it could be confirmed whether the sharp knife was a murder weapon.

For this, only a slightly experienced autopsy can go wrong.

What Chen Yan cared about was the description of Zhang Hui’s stab wound in the autopsy report.

Zhang Hui’s abdominal stab wound was about 4 cm deep, but no internal organs such as the stomach were injured.

Two stab wounds on the back, one on the left and one on the right.

The stab wound on the right side was 3 cm deep and stuck to the ribs on the back, but no internal organs were injured.

The left stab wound was 12 cm deep, piercing the heart, causing Zhang Hui to die on the spot.

There were three photos of stab wounds in the autopsy report, and it was these three photos that made Chen Yan a little puzzled.

Murder is not so easy to kill.

Human vitality is also very tenacious.

Especially for knife wounds, this kind of sharp weapon injury, if it does not hit the vital point, but damages the heart, arteries and other important parts, even if the average person stabs a dozen or twenty knives, it will not necessarily kill a person.

For example, if you stab a person in the abdomen with a knife, if you don’t know the location of important organs such as the spleen and kidney, and stab a few times in a row, it may not necessarily hurt the stomach and other organs.

In other words, even if injured, people will not die immediately.

It is even possible to live for a long time, and it is possible to take measures to stop the bleeding and wait for rescue to come.

Most abdominal stabs cause death not because of damage to any vital organ, but because of excessive blood loss over time.

The same goes for stabbing in the chest or back.

A stab wound anywhere other than the heart will not cause immediate death.

For example, the three stab wounds on Zhang Hui’s body, the stab wound on the abdomen and the stab wound on the right side of the back are not fatal.

These two stab wounds can only make Zhang Hui lose part of his mobility, but it is impossible to kill him. Zhang Hui’s fatal wound was the knife that pierced the heart on the left side of his back.

Chen Yan, who is proficient in fighting, autopsy skills and knife cognitive maps, knows this.

These three stab wounds give Chen Yan the feeling…

Like it wasn’t stabbed by one.

Because the knife that pierced the heart on the left side of Zhang Hui’s back was particularly accurate!

This knife avoided the protection of the back ribs on the heart, and inserted it through the gap between the fourth and fifth ribs, without hurting the bones at all.

A knife pierced the heart, severing the coronary crown, causing massive blood loss in the body.

Just this knife, Zhang Hui will be completely dead within ten seconds.

This precision…

Can Wang Xia do it?

If it was intentional, then Wang Xia would not be able to do it without special training.

If it’s a coincidence, then it’s too coincidental.

funeral parlor.

Chen Yan personally inspected Zhang Hui’s body.

As with the conclusions in the practice report, there are really no other issues.

All that’s left is to investigate the clues just discovered.

The meeting room of the Hulu City Detective Team.

Chen Yan organized a case analysis meeting.

“First, conduct a detailed investigation of Wang Xia’s past medical history.”

“We found half a tablet of fluoxetine, a controlled psychoactive drug for depression, in the drawer of the dressing table used by Wang Xia in the master bedroom.”

“If Wang Xia is determined to have a history of depression, then whether she committed murder or whether she committed suicide will have to be re-determined.”

If Wang Xia suffers from depression, then Wang Xia’s suicide is most likely because Zhang Hui’s death, which was stimulated by external factors, caused her to fall ill and commit suicide.

Or because of the environment in the prison or the stimulation of the interrogation, Wang Xia committed suicide.

However, judging from the writing on the wall before Wang Xia’s death, if Wang Xia really suffers from depression, then it seems that she may not really be the murderer.

On the other hand, if Wang Xia is depressed, are there other people at the scene on the day of the crime?

It is difficult to determine whether there are other people who killed Zhang Hui, because Wang Xia suffers from depression and has communication barriers. Even if she sees the murderer, she may not be able to express it.

“Yellow team, you follow up on this matter.”

If Wang Xia really has depression, then the treatment should also be in the hospital in Hulu City. If Huang Guojun investigates this, it should be faster.

“Second,” Chen Yan looked at Liu Qingshan: “About Zhang Hui’s background investigation.”

“After the incident, Captain Huang and the others have conducted a more detailed investigation of Zhang Hui’s background, but…”

Chen Yan operated the projection, and what was displayed was the hot air limited edition keyboard that was worth tens of thousands of dollars on the computer desk in Zhang Hui’s study.

“I found this keyboard in Zhang Hui’s study.”

“It’s a very expensive limited-edition mechanical keyboard, worth about 10,000 yuan.”

“People who use this keyboard are either keyboard enthusiasts or work with special keyboard requirements.”

“It’s unlikely that Zhang Hui is a keyboard enthusiast because we didn’t find any other keyboards in his house.”

A keyboard enthusiast cannot have only one keyboard. In a previous life, Chen Yan had a college classmate who was a keyboard enthusiast.

Living in a house with 2 bedrooms and 1 living room, there is a shelf separated from the small bedroom, and dozens of various keyboards are placed.

“While other job types have higher keyboard requirements, they are most likely to be hackers or text workers.”

“But the computer configuration in Zhang Hui’s study is not high, it is an ordinary desktop computer that costs three to five thousand yuan, so the possibility of Zhang Hui being a hacker is very low.”

“According to Captain Huang Guojun’s previous investigation results, Zhang Hui is engaged in the research of new chemical materials at the 301 Research Institute of Hulu City, not the work of writing.”

“But according to the browsing records on Zhang Hui’s computer, Zhang Hui often browses some sites.”

“So, check to see if this Zhang Hui is a part-time writer.”

“Yes!”

“Thirdly, Wang Gang, you are here to take the lead and take charge of checking all the surveillance videos in Zijin Community on the day of the crime.”

“Check all the outsiders that day!”

In the early stage, because the case was relatively clear, Wang Xia knelt in blood after killing with a murder weapon, so Huang Guojun did not do a large-scale investigation.

The murderer was at the scene and was caught at the time of the incident. What is the investigation?

But now it seems that Zhang Hui’s death is likely to be something else.

Chen Yan naturally would not let such an important clue go.

However, when Chen Yan first entered the Zijin Community, he found that there were relatively few surveillance cameras in the Zijin Community. He wondered if he could find useful clues.

Everyone started to perform new tasks according to the work arrangement, and Chen Yan was not idle.

In the office, Chen Yan was carefully reading through the case file of Zhang Hui’s death.

Taking advantage of this time, Chen Yan wanted to review the entire file.

*********

On the evening of July 12, 10:08.

The Hulu City Detective Unit 1 received a call to report the case, and ten minutes later, the detectives arrived at the scene.

The reporter Song Jun, the tenant of Unit 305, Unit 1, Building 3, Zijin Garden, is Zhang Hui’s neighbor.

The records in the dossier are very detailed, and there are also records made by Song Jun at that time.

“I was lying on the bed and was about to go to sleep, but when I was about to fall asleep, I heard someone shouting outside and woke me up.”

This is the first sentence in Song Jun’s inquiry transcript.

“My sleep quality is not good. I sleep very lightly, and I can wake up with a little movement.”

“I was afraid that they would make noise again when I fell asleep, so I went out and tried to reason with the neighbor, so that they wouldn’t be so loud at night.”

“As a result, as soon as I opened the door, I saw the door of the room opposite 301 was open. Their gentlemen were lying on the ground, and the woman was kneeling in a pool of blood with a sharp knife in her hand!”

“Damn it, it almost scared me to pee, you don’t know.”

“After I was done, I immediately called the police. I was afraid that the woman would run away, but I didn’t dare to go forward, so I called out the people in 303 and 304.”

“Didn’t you call the 302 person?”

“Shout, no one came out from that house. I have seen 302’s neighbor, who seems to be a doctor. He often works night shifts, and he should not be at home at night.”

“Not long after that, the police came.”

“Is there anything unusual about this resident of 301 recently?”

“There’s nothing unusual. I know the man from their family, but I don’t know him very well. He seems to be doing research.”

“We occasionally meet in the elevator when we go to work, and sometimes we chat for a while, but we are not particularly familiar with it.”

“When you close the door, it’s your family’s life, and you don’t usually get in touch with your neighbors.”

Song Jun’s transcript is very short, mainly explaining what happened before and after Song Jun called the police after discovering that Zhang Hui was killed.

Transcripts about 303 and 304 tenants are also very simple.

What they saw when they opened the door was basically the same as what Song Jun described, except that in their records, when they came out, Song Jun was already at the door of 305.

It was indeed Song Jun who called them out.

Judging from the file, none of the three neighbors behaved abnormally, and the scenes they described were similar.

Putting down the inquiry record, Chen Yan picked up the mobile phone and arranged work for Zhao Bing: “Conduct background checks on several of Zhang Hui’s neighbors, focusing on what these people do.”

Hanging up the phone, Chen Yan continued to review the files.

In addition to the written records, the dossier also contains many photos taken at the scene of the crime.

After receiving a call from the police and detectives arriving at the scene, Zhang Hui was confirmed dead.

According to the scene shown in the photo, Zhang Hui was in a crawling and lying position with his left hand in front and his right hand slightly behind.

The specific position is the left hand, which has just crossed the threshold, and the right hand has not crossed the threshold.

At that time, Wang Xia was kneeling in a pool of blood between Zhang Hui’s legs, holding a sharp knife in both hands, and the door was wide open.

Picking up the photo and looking at it carefully, Wang Xia’s expression at that time was a little blank, her eyes were blank, and she seemed to be staring at the sharp knife in her hand.

Looking away, Chen Yan stared at the door of the room.

Not right!

Especially wrong.

When he was at the scene just now, Chen Yan had carefully observed the entrance door of Zhang Hui’s house, and there was no blood on the door handle or on the door panel.

In this photo taken at the time, Chen Yan also did not find any bloodstains on the door handle and door panel.

This is a bit strange. According to Zhang Hui’s crawling and lying posture at the time, Zhang Hui’s left hand has already stretched out beyond the threshold.

And Zhang Hui’s left hand was covered in blood, which is strange here.

How did the door of Zhang Hui’s house open?

There is basically no possibility for Zhang Hui to open it, because Zhang Hui has blood on his hand. If he opens the door, there will definitely be blood on the door handle and door panel.

Judging from the posture Zhang Hui was lying on the ground at that time, Zhang Hui would definitely leave a lot of blood on the door handle and door panel when he opened the door at that time, but the panel and door handle were very clean and there was no blood.

So is it the door that Wang Xia opened?

It seems unlikely that if Wang Xia opens the door after killing her, and her hands are stained with blood, then blood will also be left on the door handle during the process of opening the door.

If you open the door before killing someone…it doesn’t make sense.

If you open the door of your house before killing someone, isn’t that an obvious way to tell outsiders that I’m going to kill someone?

At present, it is suspected that Wang Xia is depressed, but it does not mean that she is mentally ill.

so!

Chen Yan suspected that there should be a third person present at the scene.

If, Chen Yan assumes that there is a third person present at the scene.

After witnessing Wang Xia kill Zhang Hui and flee, is there any possibility?

Of course there is.

But here comes the problem, there are no other people’s fingerprints on the doorknob.

If there was a third person at the scene who did not participate in the killing of Zhang Hui, then this person would definitely run away in the face of the fact that Wang Xia killed Zhang Hui, because this person was afraid that Wang Xia would also kill him.

But in this case, the third person scrambled for the door and fled, and would definitely leave fingerprints on the doorknob.

Because he is running for his life, it is impossible to wear gloves or wipe off his fingerprints after opening the door at this time?

Therefore, it seems unlikely that there is a logical omission in this assumption.

The remaining possibility is that the third person at the scene also participated in the killing of Zhang Hui, and even this third person was the mastermind.

If this person is more familiar with Zhang Hui and Wang Xia and knows that Wang Xia suffers from depression, then he will put the knife into Wang Xia’s hand after the murder, frame Wang Xia as a murderer, and he will open the door and leave by himself. a possibility?

Of course there is, but this possibility is indeed very small.

Because even if the other party knew that Wang Xia suffered from depression, he could not be sure that Wang Xia would not explain it during the interrogation, right?

If there is indeed a third person who framed Wang Xia, logically speaking, everything is smooth.

Why Wang Xia committed suicide and why she left the words on the wall that she did not kill can be explained.

Because Wang Xia suffers from depression, she is unable to communicate and communicate, and has no way to tell the criminal suspect she knows in her heart, so she can only leave some clues and evidence through suicide.

This can also explain why there are no bloodstains left on the doorknob and door panel of Zhang Hui’s house.

Of course, this is just a situation that Chen Yan hypothesized based on the existing clues.

At 7:30 in the evening, Huang Guojun was the first to bring back the news.

In the conference room, Huang Guojun began to report the relevant situation: “Team Leader Chen, Wang Xia’s past medical history has been checked.”

At this moment, Huang Guojun looked very serious.

It can be seen that Huang Guojun’s investigation results on Wang Xia’s past medical history should be very valuable.

“We found a case of Wang Xia’s treatment for depression in the First People’s Hospital of Hulu City.”

“According to Wang Xia’s attending doctor, Wang Xia suffers from moderate depression and is accompanied by a very serious communication disorder.”

“Wang Xia went to the First People’s Hospital for treatment for the first time. It was two years ago, one year after she married Zhang Hui, and after one and a half years of treatment, that is, in February in the first half of this year, Wang Xia’s condition began to deteriorate. a big improvement.”

“Wang Xia’s depression has been greatly controlled. Without external stimulation, she has basically recovered, but the communication disorder is still very serious.”

“The fluoxetine tablets we found at Wang Xia’s house were prescribed by the First People’s Hospital.”

“I asked Wang Xia’s attending doctor for information about the case.”

“I learned from Wang Xia’s attending doctor that, judging from Wang Xia’s condition, the information she left behind when she committed suicide in the detention center should be true. UU Reading www.uukanshu.com”

“Patients with depression and communication impairments are unlikely to lie. From the information they have obtained from their clinical experience, this type of patients just have difficulty expressing what they are thinking or knowing. Once they express what they want to express, it is very unlikely that they will lie.”

“Moreover, according to the doctor’s judgment, Wang Xia’s behavior during her detention has indicated that she was suffering from a depressive episode.”

“The doctor’s suggestion is that from a medical point of view, Wang Xia’s suicide should have been triggered by an episode of depression. Of course, the specific reason must have come from external stimuli, such as Zhang Hui’s death!”

The information that Wang Xia suffers from depression has been confirmed.

Moreover, Wang Xia’s depression is relatively serious, it is moderate depression, and it is accompanied by serious communication barriers.

This is also the reason why Wang Xia did not cooperate with the interrogation after being arrested.

Wang Xia’s communication barrier makes it impossible for her to communicate with other people like a normal person.

Moreover, judging by Wang Xia’s condition, the information she expressed is likely to be true.

In other words, the 10 words Wang Xia wrote on the wall before committing suicide should be true.
