Chen Yi came to the door of the study.

The woman was still a little frightened, although there were police inside and outside the villa now, but it could not give her a sense of security.

Obsessive-compulsive disorder made her sneak into the study from time to time, and quickly diverted her gaze.

Pale complexion, sweaty forehead, tight nerves.

This woman should be scared a lot.

In their thirties, many of them have never seen a dead person, and most of their elderly relatives are still alive.

Suddenly encountered, the average psychological quality must be afraid.

"I ...... That's all I know. ”

"I'm just a worker, and I have nothing to do with it!"

Zhuo Yun's conversation with her was almost over, and the woman estimated that she had watched too many TV series, and tried to clear her suspicions, although she knew that it was useless.

Zhuo Yun: "Okay, I probably know. ”

"You go downstairs first to calm down, if there is any problem, we will look for you again."

The woman nodded lightly and turned to leave.

Chen Yi stepped forward and looked at her back as she left, Zhuo Yun spoke: "When I came to knock on the door and ask Tang Yiping if he needed supper, I pushed the door in and found that the other party was dead." ”

Chen Yi nodded slightly: "When will Tang Yiping return home?" ”

Zhuo Yun: "It's about nine o'clock." ”

"Judging from the distance between the city bureau and here, it should be that I didn't go anywhere after leaving the city bureau, and went home directly."

"According to what the nanny said, Tang Yiping didn't do anything after returning home, didn't even eat, and went directly into the study."

"During this time, the nanny came to deliver a cup of hot water."

"When I came again, I just asked the other party if they needed a supper, and the interval was about three hours."

"So, the time of death is within three hours."

Hearing this, Chen Yi raised his head and glanced at all corners of the ceiling.

Seeing this, Zhuo Yun said: "There is no surveillance, but there is one in the study, and Jiang Xiaoxin is calling up video materials." ”

It is not surprising that such a big boss installs a surveillance camera in his study.

It may be for anti-theft, or it may be for other purposes, but in short, there are many functions.

Since the crime scene is monitored, it makes it less difficult for the police to investigate.

As long as there is no fault in the monitoring, it means that Tang Yiping's death process has been mastered.

This is quite rare in homicides, and it saves the police a lot of investigative work.

Chen Yi fell into a deep groan, he still hadn't reacted a little yet, mainly because Tang Yiping's death time was too strange.

He was framed for rape just now, and died inexplicably at home a few hours later.

There won't be any connection between the two, right?

It's not right, Tang Yiping just went to the city bureau for a walk, what connection can he have?

At the moment, I don't know anything about the lack of clues, so I can only wait for the results of the investigation at the scene.

And......

Tang Yiping's death seems to be the same as Wang Lihua's, and it doesn't look like he killed him on the surface.

Before he died, he covered his chest with a painful expression, did he have a heart problem? Or poisoning?

In a few seconds, Chen Yi habitually went through the questions he encountered at the moment in his mind.

"Chen Yi, do you think there is something wrong here?" Zhuo Yun spoke, interrupting Chen Yi's thoughts.

Chen Yi raised his head: "Are you referring to Wang Yan's false accusation?" ”

Zhuo Yun nodded: "That's right." ”

"I was falsely accused of going to the city bureau at night, and I died in the early hours of the morning when I came home."

"This is too suspicious, isn't there a connection between the two things?"

Chen Yi said: "Normal thinking should be...... There is a connection, but there is no evidence or clues to support it now. ”

"The top priority is to determine the cause of death first, and find out what Tang Yiping died."

Zhuo Yun nodded: "Yes." ”

Time passed slowly, and during this time the forensic assistant also arrived and joined the work of the autopsy.

About half an hour later, Chen Yi and Zhuo Yun walked into the study and stood next to Fang Shuyu.

"How's it going?" It was Zhuo Yun who spoke.

Fang Shuyu squatted there and was silent for a moment, then raised his head slightly and said, "Cardiac arrest." ”

"Cardiac arrest??" Zhuo Yun was stunned for a moment, and then spoke: "Died unexpectedly?!" ”

Fang Shuyu didn't answer Zhuo Yun's question, and said to himself: "The pupils are dilated, the face is cyanotic, the expression is distorted, and there are no wounds on the whole body for the time being, which is in line with the clinical manifestations of cardiac arrest." ”

"So far."

"If you want to further determine the cause of death, you need to go back to the city bureau for a full autopsy."

"And you need to find out if there's something wrong with his heart."

Zhuo Yun: "Uh......"

As a result of cardiac arrest, he was a little surprised.

Is it a coincidence that he left the city bureau and died?

Chen Yi stared at Tang Yiping's corpse, then turned his gaze to the mobile phone that fell to the ground, and then turned his head to look at the nearby window.

"From the scene of death, the inference of cardiac arrest can also be demonstrated."

"Tang Yiping should have been standing in front of the window on the phone before he died, and suddenly felt discomfort in his chest, covered it with his left hand, his expression began to be painful, and then he slowly fell to the ground."

"The best time to rescue a cardiac arrest is four minutes, and more than six minutes is very dangerous."

Hearing this, Zhuo Yun subconsciously spoke: "Then why is the nanny calling the police?" Didn't the caller notice that something was wrong? ”

Chen Yi glanced at him and said, "Brother Yun, you got to the point, and you reacted quickly. ”

"That's right, who is Tang Yiping talking to on the phone, and the other party didn't notice anything abnormal?"

"This matter lacks reasonableness, unless the moment the phone just hung up, Tang Yiping suddenly felt unwell."

Hearing this, Zhuo Yun couldn't help but straighten his waist.

After the previous cases, he had already classified Chen Yi's IQ into the category of demons, and he felt very comfortable to be praised by the other party.

It's not that bad to represent yourself.

Several people naturally didn't know Zhuo Yun's careful thoughts, and Fang Shuyu spoke at this time: "After checking the call records, it will be clear immediately." ”

"It's really weird, I don't think it's going to be that coincidental."

She also participated in the analysis of the case, probably because she had been with Chen Yi for a long time recently.

Zhuo Yun stepped forward, put on gloves and picked up the mobile phone on the ground.

The screen automatically lights up, with facial recognition and password, which needs to be brought back to the bureau to unlock.

Or, check the call history directly, both methods are fine.

Putting the mobile phone into the evidence bag, Zhuo Yun handed it to the police officer next to him.

Chen Yi spoke: "Brother Yun, when the on-site investigation is over, let everyone go back to rest first, and talk about it when it is dawn." ”

"The forensic doctor, I'll keep an eye on it, and I'll do it instead."

In the early morning of a sudden murder, the division of labor must be clear, and you can't leave it alone, and you can't put it all into work, otherwise the efficiency of the next day will be very low.

The most important and urgent thing is the autopsy, so the forensic department needs to work overtime.

Other questions such as testing and visits, can be done first.

Zhuo Yun nodded: "Okay, I know, it will be arranged." ”

"Don't be too tired, after you have the results, you can rest quickly, you can sleep more, and the preliminary investigation can be handed over to me."

Chen Yi snorted and said, "By the way, let Sister Jiang leave the surveillance video, I want to take a look." ”

Zhuo Yun: "No problem, I'll explain it to her." ”

The rest of the time, Chen Yi came to the window, looked carefully centimeter by centimeter, and finally came to the conclusion that there were no tiny holes.

He's seen a lot of bizarre things.

If Tang Yiping died of homicide, if there was no second person in the study when Tang Yiping died, then there is a possibility, the murderer used a sophisticated firing device to penetrate the glass and hit with one blow.

At the moment, it doesn't seem to be.

……

City Bureau.

Forensic Medicine.

It was already past three o'clock in the morning, and Chen Yi did not participate in the work of the full autopsy, but sat there and waited.

Fang Shuyu and the forensic assistant are busy.

According to the data, Tang Yiping no longer has immediate family members, and the dissection work can be carried out directly, but it has not yet reached that step.

After a long time, the forensic assistant took off his mask and looked at it.

"There are no suspicious wounds on the whole body, and there are no signs of poisoning for the time being, and toxicological tests are needed to determine the possibility of blood drug residues."

Chen Yi: "Let's dissect, the focus is on the heart, I'll go see the surveillance video." ”

"After that, you can go back and rest, and the autopsy report can be placed in the case handling hall."

Fang Shuyu: "Okay, don't worry." ”

Chen Yi nodded, got up and left the forensic office.

In the case handling hall, Chen Yi sat in front of the computer and clicked on the video file left by Jiang Xiaoxin.

The screen lights up.

This is Tang Yiping's study, the camera position is facing the desk, the angle is very wide, although there is a blind spot, it is not big, and it can almost achieve full coverage.

At this time, Tang Yiping was sitting there quietly, drinking the boiled water in his hand one by one.

He didn't look at the papers, he didn't look at his phone, he just sat there in a daze, not knowing what he was thinking.

At this time, it was around twelve o'clock.

Tang Yiping sat like this for nearly an hour, and at this moment the mobile phone on the desktop lit up, and he picked it up and connected it.

There is no sound in the video, indicating that the surveillance camera does not have built-in audio equipment, so it is impossible to hear what Tang Yiping is saying at all.

It seems that Tang Yiping also took into account his privacy, although he installed a camera, but only stayed on the image.

After dozens of seconds of talking, Tang Yiping suddenly stood up and walked to the window.

He looked at the night in the distance and continued to make phone calls.

From this angle, Tang Yiping's right hand and mobile phone blocked the side of his face, and he couldn't see his expression.

Time passed slowly, and at a certain moment, Tang Yiping raised his hand to cover his chest, staggered under his feet, and slowly fell to the ground, his phone falling to the side.

This is the whole process of Tang Yiping's death.

From beginning to end, there was no second person in the study.

Chen Yi had already checked the window glass before, and there were indeed no sharp pinholes, and the glass was not thin, and if the needles penetrated, it should leave a spiderweb-like diffusion crack.

"Accidental death?"

Four words popped up in Chen Yi's mind.

According to the conversation with Tang Yiping last night, this person seems to be a bit problematic, coupled with Wang Yan's false accusation incident, as well as the precedent of Wang Lihua's killing.

This made Chen Yi very skeptical of this conclusion.

"Let's get some sleep."

Chen Yi is not iron-clad, affecting his thinking and judgment all night, he turned off the video and got up to find a folding bed, and quickly fell asleep.

At about ten o'clock in the morning, Chen Yi opened his eyes and was woken up by the chaotic sound of work.

He sat up sharply and glanced at the time, then tapped his newly awakened brain.

Seeing that Chen Yi was awake, Zhuo Yun came over with a glass of water and handed it to the other party.

"Thank you."

Chen Yi took it.

When Chen Yi was drinking water, Zhuo Yun spoke: "Tang Yiping's call record has been checked, guess what?" ”

Chen Yi didn't raise his head and said: "Black card, I can't find the owner." ”

Zhuo Yun was stunned for a moment: "How do you know??" ”

Chen Yi stood up from the folding bed, put the water cup on the table, and said: "I have watched the surveillance video, the phone was not interrupted when Tang Yiping died, but the other party did not choose to call the police or call an ambulance." ”

"There are two possibilities for this scenario."

"First, the other party's purpose is not pure, so the call record is a major clue, and the police will know it as soon as they check it, but anyone who is smart will choose a black card."

"Second, the relationship between the other party and Tang Yiping was originally very poor, and the call so late may be because of a private matter, but after sensing that Tang Yiping was suspected of having an accident, he decisively chose not to care about himself and hung it high."

"If it's the second possibility, you won't let me guess, but just say the name."

After listening, Zhuo Yun's face froze: "Uh...... Chen Yi, you don't even let go of my psychology, a bit of analysis, right? ”

Chen Yi chuckled: "It's just subconscious, get used to it." ”

"Well, can you find the source?"

Now the mobile phone number is a real-name registration for the whole people, but the black number still exists.

The current scale is: you can use it yourself, but you can't sell it to others.

Before Tang Yiping died, he received a call from a black card, which undoubtedly directly told the police that there might be some problems with his death.

But what exactly the problem is, it is impossible to know now.

Zhuo Yun shook his head: "I can't find it, where can I check it." ”

"Since the other party chose to use the black card, he obviously didn't want the police to find out his identity, in this case, Tang Yiping's death would not be right."

Chen Yi snorted and said, "This is one of the questions, and there is another. ”

"Why did the other party make this call? Is it necessary? ”

This question made Zhuo Yun ponder, and he said, "Yes, why do you have to fight?" ”

"If the caller has something to do with Tang Yiping's death, he can do nothing at all, unless he ......"

"Make a phone call and taunt two sentences, out of anger? Or tell Tang Yiping that you are dying, I am very happy. ”

"Does it matter?"

Chen Yi nodded: "Reasonable, and the possibility is not small." ”

"But if you can't find anyone, let's let it go first."

After speaking, he picked up the autopsy report on the table, it should have been placed here by Fang Shuyu in the early hours of the morning.

"Where's Shuyu?"

Zhuo Yun: "Go back and rest, I'll let her rest and come back in the afternoon." ”

"How's it going, enough friends?"

Chen Yi wondered: "As a team leader, a senior criminal police officer of the criminal investigation detachment, shouldn't he care about his colleagues?" What does it have to do with me. ”

Zhuo Yun was speechless: "Pretend, you will continue to pretend with me." ”

"Okay, let's not talk about this first, the test results of that glass of water have come out, it's normal, it's just ordinary water, and there are no other ingredients in it."

"I have also read this autopsy report, and the toxicology test is normal."

"The only thing that is abnormal is Tang Yiping's heart, there seems to be a problem, but he has no history of heart disease, is it an acquired illness that he didn't have time to investigate?"

"All I can say is that it increases the likelihood of accidental death."

Hearing this, Chen Yi raised his eyebrows: "Oh? ”

It seems that Zhuo Yun has almost done the investigation work in the early stage, and has obtained all of Tang Yiping's medical records.
