Chapter 572 Puppet on Strings

Case handling cannot be based on guesswork.

Evidence, everything requires evidence.

Dan City Detective Team.

Chen Yan is organizing the first case analysis meeting.

First, Zhang Yaoming explained the basic situation of the case.

"Wang Luyao, female, 36 years old. At 7:59 this morning, the jurisdictional team received an alarm call that someone died in Runhua Community."

"I personally led the team immediately and arrived at the scene of the crime at 8:11. After that, the on-site investigation investigators of the detective team conducted a preliminary investigation of the death scene of the deceased."

On the projector was a photo of the living room where the deceased died.

"First, the time of death of the deceased Wang Luyao was 3 o'clock this morning. The fatal injury was a knife wound that nearly penetrated the abdomen and injured the spleen. The cause of death was death from excessive blood loss."

"Secondly, before death, the deceased was stabbed 32 times in his body. There were multiple stab wounds on the inside and outside of his left arm, chest, abdomen and legs, most of which were minor exploratory stab wounds."

"Because there were too many stab wounds on the deceased's body, we immediately suspected it was homicide and then conducted some detailed inspections of the room."

"However, we found no traces in the living room where the crime occurred, no strange fingerprints, hair or footprints."

"After analyzing the blood stains, we also concluded that there were no traces of outsiders at the scene."

"In addition, we checked the security door of the house and found no signs of damage, ruling out the possibility of someone breaking in intentionally."

"At the same time, we reviewed the video of the deceased Wang Luyao in the corridor after she came home from work last night, and found no trace of strangers entering."

"Through some findings at the scene, we have initially concluded that Wang Luyao died of suicide."

"However," Zhang Yaoming changed his voice: "Out of caution and because Wang Luyao suffered too many stab wounds, the team reported the case to the Liao Provincial Detective Brigade."

"Team Leader Chen, these are the details of the case we discovered earlier."

Chen Yan nodded and looked around: "We are all old acquaintances. This case is very difficult."

Chen Yan's expression was a little serious, and he took the projector pen from Zhang Yaoming's hand: "The previous work of the Dan City Detective Team was carried out in strict accordance with the process."

"From a process perspective and from the importance Team Zhang attaches to the case, there is no problem."

Chen Yan affirmed Zhang Yaoming and the Dan City Detective Team's previous work.

This is not a polite statement, Zhang Yaoming's early work was indeed very solid.

Personnel investigation, video review, on-site trace inspection, etc., every aspect is in place.

Generally speaking, on these basis, the case can basically be characterized.

However, out of caution and suspicion about the manner in which the deceased committed suicide, Zhang Yaoming reported the case without hesitation.

Only then did Chen Yan come over to take over the case.

"Before arriving at the scene at noon, Team Zhang had already reported the details of the case to me, and then I carefully read the file records."

"At the scene, I compared the situation at the scene with the previous inspections conducted by the Dan City Detective Team, and I also came to the conclusion that the deceased committed suicide."

"But." Chen Yan switched the projection.

Above is the shape of a corpse stain at the base of the thigh on the back of the deceased.

"While transporting the body for autopsy, we discovered that the spots on Wang Luyao's body were abnormal."

Everyone present has experience with the characteristics and patterns of corpse spots.

All corpses develop body spots after death.

Wang Luyao's posture after her death was lying diagonally on the sofa. Judging from normal conditions, there would be corresponding compression marks on her back and buttocks.

However, the photo projected above is clearly different.

There are a row of button-like marks on the body's back, and oval-shaped marks on the lower sides of the legs.

This situation...

"When the deceased died, he would only have such traces of body spots if he was sitting on someone else."

"Moreover, the other party should be wearing a buttoned coat!"

"That is to say, when Wang Luyao died, there must have been other people at the scene!"

Wow!

After speaking, many people began to communicate.

"Team Leader Chen, judging from the shape of the body spots, it is indeed a bit strange, but there was no trace of anyone else appearing in the living room of the deceased's home."

The speaker was Han Lei, deputy captain of the Dan City Detective Team: "Especially the blood trace analysis, I led the team to do it myself."

"I can confirm that the blood traces of the deceased are very natural. If the deceased was killed, how did the other party avoid so much blood stains?"

"Wang Luyao was stabbed 32 times, and all the blood in her body was almost gone. There were blood stains everywhere in the living room. If the other party was at the scene, it would be impossible not to leave any traces."

Han Lei's judgment was actually correct.

The more complex the scene, the more traces the murderer may leave behind.

Judging from Wang Luyao's death scene, if there was someone, unless they were floating in the air, they would definitely destroy the blood stains.

Chen Yan looked at Han Lei: "What Vice Captain Han said is correct."

"In such a complicated scene, if there is really a murderer, it is impossible for the other party to avoid all the blood stains without leaving any clues."

"But... what if all the movements of the murderer and the deceased overlapped?"

Overlap?

"what do you mean?"

Chen Yan left his seat and walked to the projection: "Everyone, look at this picture."

"The deceased was lying sideways on the sofa. I once reconstructed the entire process of the deceased stabbing himself at the scene."

"It can be determined that the wounds on the deceased's body were caused by the deceased's right hand being able to hold a knife."

"However, you can see several stab wounds on the deceased's arms and outer thighs."

"There are no arteries in these locations. Cutting these places, no matter how deep the wound is, will not be life-threatening."

"However, Wang Luyao left multiple stab wounds on her left arm and outer thigh."

"A stab wound in this position is not consistent with Wang Luyao's intention to commit suicide."

"Also, please pay attention to the order of these wounds."

The projection switched, and all the wounds on Wang Luyao's body were marked with serial numbers: "From the shape of the deceased's wounds and traces of bleeding, we measured the order of the 32 stab wounds on the deceased."

"The injuries to the arms and thighs appeared first, then the stab wounds to the chest, and finally the stab wounds to the abdomen."

"Why this order?"

"And we measured the time when the first stab wound appeared and the time when the last stab wound appeared. The interval was about an hour!"

"In one hour, Wang Luyao committed suicide, not torture!"

"From a general psychological point of view, if a person decides to commit suicide, he or she will generally want to end his life as soon as possible."

"But Wang Luyao's suicide process actually lasted an hour!"

"It doesn't make sense."

Chen Yan turned to look at Han Lei: "As for what Captain Han said, why there are no traces of the murderer at the scene, because the murderer and the deceased have been keeping synchronized movements during the entire process."

"In other words, the murderer controlled Wang Luyao to complete the so-called suicide!"

"control?"

"Yes, it's control!"

"Chaoyang, Wang Gang, come here."

"Chaoyang sat on the sofa, and Wang Gang sat on Chaoyang."

The two sat next to each other according to Chen Yan's request. Afterwards, Chen Yan casually handed the air conditioner remote control on the table to Wang Gang.

Then, Chen Yan asked Zhang Chaoyang to hold Wang Gang's right hand, and Wang Gang held the remote control in his right hand.

"Wang Gang, don't move, don't use force with one hand. Chaoyang, control Wang Gang's right hand and stab Wang Gang in the abdomen."

Stab in the air!

"Everyone...do you understand?"

Marionette!

It turns out that’s what Chen Yan meant!

Han Lei looked excited and ran to Zhang Chaoyang and Wang Gang, looking forward from behind them.

"So that's it!"

"Team Leader Chen, you mean that Wang Luyao's suicide was actually caused by someone controlling her behind her back!"

"And with such a sitting position, the murderer is equivalent to overlapping the deceased, so he will not affect the direction of the blood spray from the wound at all, and naturally will not destroy the blood stains!"

Gan!

This murderer... is a bit awesome.

He was actually using a puppet method to manipulate Wang Luyao to "commit suicide!"

No wonder it left no trace.

What happened!

【Ding! The strongest police training system mission is released. 】

[Detect a suspenseful suicide case. The deadline is five days. Complete the task and you will be rewarded with three cell enhancements. If you fail or exceed the deadline, the task reward will be cancelled. 】

The nature of the case is determined and the system issues tasks.

"But...how did this person enter Wang Luyao's house, and how did he leave?"

Han Lei has also seen the surveillance video, there is no doubt about it!

After hearing Han Lei's question, Chen Yan fell silent slightly.

This was also the most doubtful part in his mind.

Chen Yan had discovered a loophole in the method of entering Wang Luyao's home.

It is the 5 minutes it takes for the surveillance video system to restart.

But how did the murderer get out?

After Wang Luyao's mother called the police and before Zhang Yaoming brought people here, Chen Yan responded one by one to everyone who entered the room.

There are 12 property management personnel, not one more person.

It is impossible for the murderer to hide in the room in advance, then blend in with the property staff, and then evacuate.

Therefore, Wang Luyao’s death time can be determined to be 3 o’clock this morning.

After this time, the surveillance system was normal. The video statement in the corridor of Wang Luyao's floor was personally viewed by Yan Yan, and no one went out.

So, how did the other party leave?

window?

Not likely either.

At the crime scene, all windows were closed.

Wang Luyao lived on the fourth floor. If the murderer had used a rope, it was still possible to escape through the window.

But if the other party really escaped through the window, where was the rope?

Why are the windows closed?

Chen Yan has checked the windows in Wang Luyao's house. They are plastic steel windows that were installed during the construction of the community. They cannot be closed from the outside, but can only be closed from the inside.

This is inconsistent with the findings at the scene.

Faced with Han Lei's questions, others had no way to explain.

Because these clues originally showed that Wang Luyao committed suicide.

However, because Wang Luyao suffered too many stab wounds, Zhang Yaoming decided to report the case and ask the crime team to take over.

"Team Leader Chen...is this a secret room murder?"

Zhang Yaoming can only guess in this direction.

First of all, Wang Luyao’s corpse had unknown marks on the body spots, which definitely did not appear for no reason.

This clue can determine that someone must have been with Wang Luyao before her death.

Of course, now we can't say that the person with her must be the murderer.

This depends on subsequent evidence.

However, judging from the logic of handling the case and the number of wounds on Wang Luyao's body, this person should be the murderer.

After all, even if a normal person commits suicide, he would not stab himself more than 30 times.

In particular, many stab wounds are not fatal injuries but exploratory stab wounds.

As an adult, it is impossible for Wang Luyao not to know where the fatal wounds are, and to cut so many knives on her arms and thighs is not so much suicide as torture.

However, the doors and windows of Wang Luyao's home were closed, and the camera in the corridor at the door was always on. The time of Wang Luyao's death was 3 a.m. this morning, and it was determined that no one came in or out after that.

And the windows can only be locked from inside. What is this if not secret room murder?

Chen Yan frowned.

Chen Yan agrees with Zhang Yaoming's judgment.

However, Chen Yan had never been exposed to so-called secret room murders.

From a scientific point of view, there is no such thing as secret room murder in this world.

The so-called secret room murder is nothing more than two possibilities.

First, before the secret room was formed, the people in the secret room were already dead.

The simplest example of this situation is fake suicide, for example, the victim is given chronic lethal drugs in advance, and the victim dies in the secret room only after the secret room is formed by the victim himself, forming the so-called secret room murder.

In fact, strictly speaking, this situation means that the victim is already destined to die before entering the secret room.

It's just that the time is delayed.

Second, it is a secret room formed by the murderer using some loopholes after death.

For example, the secret room murder case that Chen Yan solved last time was a so-called secret room, but the furniture in the secret room was used to block the exit.

Let the victim mistakenly believe that a secret room is formed.

The scene where Wang Luyao was killed obviously couldn't be the first one.

Because there were traces of other people's presence at the scene.

The special corpse spots on Wang Luyao's body are proof of this.

So, how did the other party achieve the second type of secret room murder?

"Like this," after a moment, Chen Yan decided to temporarily arrange other work. This is how solving a case is, not every clue can be solved, and not all questions can be answered at the beginning.

"Now, based on the special corpse spots on Wang Luyao's back and legs, it can be concluded that there were other people around Wang Luyao when she died."

"Although we have not yet discovered how this person entered and left Wang Luyao's house."

"However, finding this person is undoubtedly the key to our solving the case."

"Team Zhang," Chen Yan looked at Zhang Yaoming: "As for Wang Luyao's identity and background investigation, our Dan City Detective Team is responsible for it."

"Telephone call records, WeChat chat records, colleague relationships, bank statements, etc., the more detailed information about Wang Luyao, the better."

"yes!"

"Second, we need to investigate all surveillance videos in Wang Luyao's community."

Chen Yan looked at Liu Qingshan: "Liu Captain, you are responsible for this matter."

"The door lock of Wang Luyao's home shows no signs of damage, so there are only two ways for the other party to enter Wang Luyao's home."

"Either this person used a key to open the door of Wang Luyao's house, or he entered Wang Luyao's house through the window."

"Judging from the current situation, only Wang Luyao's husband and Wang Luyao's parents have the keys to her home."

"Judging from the current clues, these people have no time to commit crimes, so who can have access to the key to Wang Luyao's house?"

"Check whether there are any records of lock changes and property maintenance records in Wang Luyao's home."

Under normal circumstances, it is impossible for an acquaintance to have the key to the home. No matter how good the relationship is, the key to the home will not be given to others.

Therefore, there is a high probability that the other party came into contact with Wang Luyao's house key due to work reasons.

"On the other hand, if the other party entered or exited through the window, it is likely to leave clues. Check the window to see if there are any traces of climbing, and see if there is any surveillance record."

"yes!"

"in addition……"

Chen Yan thought for a moment and looked at Zhang Yaoming: "I'll go meet Wang Luyao's husband in person."

The first case analysis meeting is over.

Interrogation Room No. 1 of the Dan City Detective Team.

Chen Yan met Wang Luyao's husband Zhao Guang.

Zhao Guang, who was sitting opposite Chen Yan, looked a little dazed, his eyes were bloodshot, and he looked unusually tired.

"Officer, it's impossible for my wife to commit suicide. You must find out how she could commit suicide!"

Before Chen Yan could speak, Zhao Guang spoke first.

"Mr. Zhao, please forgive me. You said that Ms. Wang Luyao could not commit suicide. What evidence do you have or why are you so sure that she will not commit suicide?"
