Forensics

"That day..."

Xu Ziyue stopped her tears and took a deep breath, "That night, when my sister came home, she was arguing with my mother. Even if I wore earphones, there would still be harsh sounds, which made me unable to concentrate. At that time I am doing my graduation internship and preparing for the postgraduate exam.”

"I don't know what they were arguing about. They were arguing very fiercely. Later, my sister went into the house to pack her things and said she was going to move out. I said, 'If you go out to live, don't come back.' Angered at her, she came over and fought me. She said, 'Did you talk bad about me when I wasn't home? Did you think I'd just walk away and leave everything to you little bitch?' She Grabbing my hair and pushing me with my knee, I pushed her unbearably, and the back of her head hit the bedside table, she bled a lot at that time, and then she stopped moving..."

Xu Ziyue began to break down and cry again: "I called her, but she didn't answer me. I went to touch her nose, but I couldn't feel the air flow. Me, I didn't mean to..."

She scratched her hair with her fingers: "My mother came in later, and I asked my mother if she wanted to take my sister to the hospital. My mother said..."

Suddenly, a noise at the door interrupted her.

A woman's voice sounded from outside the door, faintly.

"Why did you arrest her? She doesn't know anything..."

Xu Ziyue hesitated.

It was Tang Lu's voice. Gu Yanchen ignored her. He took a step forward, pressed the armrest of Xu Ziyue's interrogation chair with his hands, and looked directly at the girl's eyes with his long and narrow eyes: "What did she say?"

Feeling a surge of pressure, Xu Ziyue replied subconsciously, and said in a trembling voice: "She said, don't call an ambulance, don't call the police, she will deal with it."

According to the autopsy results, Xu Yapei probably suffered a head injury and fell into a coma during the fight with Xu Ziyue at that time, which caused shock.The unconscious person's breathing was weak, so Xu Ziyue thought she had killed her sister.

After Xu Ziyue finished his confession, Gu Yanchen opened the door of the interrogation room.

Tang Lu stood at the door, still wanting to argue, but when she saw Gu Yanchen, she lowered her head and swallowed her words.

No noise is allowed inside the police station, and she knows this.

Xu Ziyue originally said that she would go home for dinner tonight, but after she finished the meal, she didn't wait for her daughter, so she realized that she rushed to the city bureau.

Now, Tang Lu stood aside and prayed silently, hoping that Xu Ziyue didn't say too much.

As long as you don't say too much, you can still hire a lawyer, and there is room for turnover...

Gu Yanchen said, "Ms. Tang, your second daughter has already confessed her crime. Now, you are the suspect who killed your eldest daughter Xu Yapei."

After speaking, he opened the interrogation room opposite and made a gesture of invitation.

Tang Lu was stunned for a moment, feeling her body suddenly fell into the icy lake.

She was still late.

Daughter has already spoken.

Tang Lu walked mechanically and walked into the interrogation room, looking at the four walls and the police on the opposite side.

Then she sat in the interrogation chair across the table.

After a few seconds of silence, the woman regained her composure. She straightened her back and said, "At the beginning, Ziyue killed Abbott by accident. I transported Abbott's body to a deserted amusement park, and left the body behind. There..."

Gu Yanchen looked into the woman's eyes, and since the afternoon when he recognized the dead body, he noticed something wrong with the woman.

But at that time, there was no direct evidence to prove her relationship with the case.

At this point in the trial of the case, a key point appeared, did Tang Lu know that Xu Yapei was imprisoned alive?

If she knew, it would be intentional homicide.

If she didn't know, then Xu Yapei just died of an accident.

Lu Ying asked: "Abandon the corpse? Then why did you lock that room?"

Tang Lu said, "I did this because I didn't want anyone to find her body."

Gu Yanchen didn't go around in circles, and directly pushed a picture of a female corpse's fingers in front of her. The peeling and broken nails were shocking to see: "The forensic autopsy and the traces at the scene all proved that Xu Yapei was still alive when he was imprisoned. "

Tang Lu looked down, then raised her head, her eyes were calm and indifferent: "I don't know. I just heard this."

Gu Yanchen looked at her with a frown, no guilt, no surprise, this is definitely not a mother's natural reaction when she finds out that she killed her child by mistake.

Now, he felt more and more that this was an intentional murder.

But how difficult is it to prove this through testimony and physical evidence?

If Tang Lu bites this point to death, it is likely to change the outcome of the trial.

Looking at the indifferent woman in front of him, Gu Yanchen thought, how can he break through her psychological defense?

At this time, Shen Junci had already changed into his work clothes, and came to the criminal investigation building with a few inspection reports.

He walked into the observation room and saw Bai Meng who was in charge of recording. Shen Junci put the inspection report aside: "The DNA comparison results came out, the deceased is Xu Yapei, and the blood stains at the door are the direct blood relatives of the deceased." The ones left have the same blood type as Tang Lu."

Then he asked Bai Meng: "How's the situation?"

Bai Mengdao: "Xu Ziyue confessed, and Team Gu is questioning Tang Lu. At present, her statement is that Xu Ziyue pushed Xu Yapei down, causing her head injury. Tang Lu only admitted that she helped her second daughter throw away the body, not that she killed anyone."

Shen Junci heard this, and looked at the interrogation room through the observation window on the side.

Bai Meng said: "Don't worry, Captain Gu is a human-shaped lie detector. You can't hide anything from him. It's just that this woman has a very good psychological quality. I don't know when this trial will end."

In the interrogation room at this time, Gu Yanchen lowered his eyebrows, looking at the information on the paper.

Tang Lu was answering his question: "I didn't stay there for a long time. After dragging her in, I sat at the door for a few minutes and then left."

While answering Gu Yanchen's question, she reached out to grab a scar on her left arm.

Gu Yanchen also noticed this detail: "The wound on your arm was cut at the scene?"

Tang Lu looked down, without denying it, she lowered her head and said, "It was scratched when Abbott was dragged in."

Shen Junci squinted his eyes and looked carefully. It was a nail scratch. On the left forearm, the wound was four centimeters long. According to the length of the iron nail and the degree of blood staining at that time, the depth of the wound was about 1.5 centimeters. At that location, only one branch of the vein can be cut.

Shen Junci listened for a while, then he suddenly thought of something, stood up and said, "I have a way to prove that she is lying."

Bai Meng asked curiously, "What method."

Shen Jun said: "It may take a little time."

Bai Meng said: "Don't worry, this woman will be detained inside tonight."

Shen Junci returned to the forensic building. There were not many forensic doctors on duty in the building, and the whole building was quiet.

He found a few photos of the crime scene, one of which was about the bloodstain on the ground, and there was a ruler on the side to measure the length, width and area of ​​the bloodstain. Although the blood had dried up, the area of ​​the blood could still be basically calculated. It is possible to count how many drops of blood flowed to the ground.

There was no surveillance at the scene, so they didn't know how long Tang Lu had been sitting there.But this piece of blood can be used as physical evidence to illustrate this point.

According to Shen Junci's estimation based on experience, it is definitely not a trace that can be left in a few minutes.

If you want to measure time more accurately, the best way is to do a simulation experiment.

Shen Junci took out the blank paper with a checker.

Rubbing the edge of the bloodstain, then placing glassware on top.

Deploying artificial blood and testing requires the cooperation of someone, and the error is relatively large.

The best way is to use someone with the same body fat percentage as Tang Lu...

Thinking of this, Shen Junci calmly rolled up his sleeves and looked at the same position.

He chose a similar nail and sterilized the arm and the murder weapon.

The height of the chair needs to be exactly the same.

Ready, Shen Junci's hand was steady, and he stabbed in towards the arm.

After a short period of pain, the bright red blood dripped down, gradually draining away every minute, and he also began to gradually approach the truth...

Gu Yanchen was still in the interrogation room, asking Tang Lu.

He couldn't believe that this woman was as utterly devoid of emotion as she appeared on the surface.

Tang Lu is a smart woman. She was a Ph.D. in her early years and worked in a research institute, researching advanced chemical materials.

After her husband died, she did not choose to remarry, but took her two daughters to adulthood.

It is said that a tiger's poison does not eat its offspring, Gu Yanchen is a little puzzled, how can Tang Lu completely ignore her daughter who is dependent on each other, and have no feelings at all?

The details of the case, the process of the case, before and after the case, witnesses and material evidence, all the details were asked one by one.

A confession gradually enriched.

Time passed by, and Tang Lu had been locked up here for two hours.

She seemed to be very cooperative and knew everything, but she always guarded the wall in her heart, biting herself to death thinking that her daughter was dead, and she was just throwing away the body.

"At that time, if you called the hospital, Xu Yapei might still be saved."

"I didn't know it at the time."

"Why didn't you call the police?"

"I thought that if the police were called to the police, Xu Ziyue's affairs would be exposed. In the spirit of protecting my second daughter, I did not call the police."

Tang Lu has been maintaining her rationality, as if the discussion with the police is not about her daughter's life or death, but a chemical formula.

"Xu Yapei is your first child, don't you have any feelings for her death?" Gu Yanchen asked, he no longer asked Tang Lu whether she knew whether Xu Yapei was dead or alive when he finally locked Xu Yapei in the room, but Start playing the emotional card.

He hoped that she could arouse even a little guilt for her daughter's death.

"There are still some feelings." Tang Lu straightened her hair and said, "It was an accident to be pregnant with Abbott. She almost ruined my job. It was my husband who insisted, so I didn't kill her. She was born prematurely. At that time, it was only four pounds and two pounds, just as big as a kitten. At that time, my husband said that she might not be able to support her. The nurse put her in the incubator, and she stretched out her little hand and stuck to mine. hand……"

Speaking of this, something else finally flashed in Tang Lu's eyes, which was the only warmth she had as a person and a mother.

Gu Yanchen asked: "But later, why did you..."

Tang Lu's voice slowly said, "Why did the relationship get worse, right? I'm very busy with work and often neglect to take care of them. She was always taken care of by the elderly until she was two years old. countable."

"Until I had Ziyue again. Abbott was excellent since she was a child, but she was not an obedient child. Her height, temper, and personality were not like mine."

She paused and said, "You probably have never had children. You will only find out when you face your parents and children. The relationship between parents and children has never been equal. They are only obliged to feed and clothe their children, and provide them with everything they can provide. This kind of non-equivalence exchange will make people look forward to it, give feelings, money, and want to return. Want Children are obedient, study well, and treat themselves well, but children will not give adults these things."

"Just like children have favorite dolls, toy cars, and dinosaur models, children have their own favorite toys. Adults also have their own favorite ways and children. Completely equal love does not exist. As long as there are two If there are more than one child, there will be comparisons."

Tang Lu talked freely in the interrogation room, as if she was talking about her parenting experience and discussing her life experiences with her friends.

Gu Yanchen brought the topic to the small black room: "Your daughter said that when they were young, you would lock them in the small room without food or drink."

In front of a weak girl, a small room will produce helplessness and fear.

It will also have a huge psychological shadow.

"That's because they are too disobedient. When Abbott was five years old, my husband found out that she had stolen money from the family and locked her in a small dark room as a punishment. At that time, I felt that such a The method seems to be good."

Tang Lu paused, and continued, "Children are different from your imagination. They are an independent individual, and they will suddenly say something that you have never taught, and even lie. Parents, they all lie, they get into trouble, and they make mistakes that they can't afford the consequences of."

"So Abbott and Ziyue, which daughter do you care more about?"

"In the beginning, I focused on training Abbott, but after she rejected my request, I turned to Ziyue. Later, I found that my preference for Abbott can inspire Ziyue's fighting spirit."

"So you're going to let them compete with each other and challenge each other?"

Tang Lu said: "Isn't that what the society will experience? The resources of this society are limited. If they don't become the top, they will be eliminated. I hope they realize this early. The competition in the school, the job position Haven’t you guys experienced all the intrigues and deceptions in the world?”

Speaking of this, Tang Lu lowered her head and said: "I think I'm already an enlightened parent. I didn't even force them to have children. I just asked them not to associate with bad men. It's for their own good. But even Such a small request, Abbott is deliberately disobeying me..."

"Why did you choose that juvenile activity center to dispose of the body?" Gu Yanchen asked.

"That's the place I would definitely take my children to during the previous holidays. If you study well, the one who is more obedient recently will be rewarded and play in it for a whole day, while the one who is not obedient will be locked up. In the activity center, listen to the teacher's lecture for a day. There are often some popular science education there, and there are some small exhibitions, such as the dangers of drug abuse and the heroic deeds of the revolutionary martyrs. I will let them memorize the words above."

"Are you using these to replace the ideological education of children?" Gu Yanchen asked again.

Tang Lu thought for a moment, then nodded.

"My life is under a lot of pressure. It is a disaster to work overtime for days and meet noisy children. So sometimes I will be a little irritable and may cause some harm to the children. I also reflect on these later."

"But what I give to my children is always the best. As long as others have it, they have it. No matter how busy I am at work, I will cook three dishes and one soup for them so that they can grow up well. I sacrificed my own During the break, take them to various training classes..."

While chatting with Tang Lu about the past, Gu Yanchen suddenly thought of a sentence.

Children are waiting for an apology from their parents, and parents may be waiting for gratitude from their children. ※

"I think your two daughters may be very different from the direction you want to raise. The current result also shows your failure." Gu Yanchen said coldly, "You killed Xu Yapei, and you let your second daughter Daughter Xu Ziyue thinks that she killed her sister, and you use this as an excuse to blackmail your second daughter so that she will not dare to resist you."

Tang Lu's hand trembled slightly, as if she had been stung, then she raised her head, as if comforting herself, and said, "Officer, those are just your speculations, Xu Ziyue just injured her sister. Xu Yapei's death , was an accident. Whatever the law will order me, I will accept. This is the end of the matter."

This is a self-defeating lie.

After that, no matter how Gu Yanchen asked her, Tang Lu kept repeating these words.

Their conversation seemed to be at a dead end, in a circle.

Gu Yanchen could feel that the woman had set up a shield in front of him, and there was no gap in it.

It seems that no matter how many questions you ask, you will never reach the core, and everything will return to the original point.

Gu Yanchen was thinking about how to change the interrogation strategy.

At this time, there was a knock on the door suddenly.

The criminal policeman in charge of recording opened the door, and Shen Junci was standing outside the door.

He wore a white forensic suit over a black shirt.

Shen Junci looked at Gu Yanchen: "Captain Gu, can I ask her a few questions?"

Gu Yanchen gestured for him to enter.

The interviews in the interrogation room are all recorded, and there must be more than two police officers present. Forensic doctors can also participate in the interrogation and provide some information.

Shen Junci put a stack of laboratory reports and test results on the small table in front of Tang Lu.

"Tang Lu, according to the bloodstains and traces at the scene of the crime, the time you stayed at the scene was not just a few minutes, but at least an hour and a half. Even if you took actions to stop the bleeding, you would stay for more than two Hours. Can you tell me what you were doing during that time?"

He has confirmed that the veins on the arm side are injured, and the blood flow is very slow, but the wound will be difficult to heal, and it will take a long time to leave such a pool of blood.

"I..." Tang Lu froze for a moment. She looked down at the test data and couldn't refute it because it was a fact.

She lied from the beginning, that is, the time she stayed at the scene of the crime.

She did sit in that chair for a long time.

Those were the most difficult two hours in her entire life, and her heart became cold when she sat there.

Tang Lu sorted out her thoughts and tried to calm herself down: "I probably sat for a while, I was too tired at that time. I don't even remember how long I sat."

Shen Junci put another autopsy sheet on the table: "Xu Yapei's injury at the back of her head can only cause her to go into shock for a short time. You and Xu Ziyue put her in the car and transported her to the east of the playground alone. door. You dragged her into the activity center, skin-to-skin, for such a long time, you didn't find out the fact that she was still alive?"

There is a big difference in the sense of touch between a living person and a dead person. A living person has a temperature and will not experience rigor stiffness. Even if they are in a coma, they will still have weak breathing.

The inexperienced Xu Ziyue would get confused in a panic, but her mother, who had been in contact with Xu Yapei for a long time later, dragged her into an abandoned playground, how could she make such a serious mistake?

"I really didn't pay attention at the time." Tang Lu's voice began to tremble.

Shen Junci continued to ask: "If you don't want to say it, then I can make a reasonable guess. Regarding those two hours, when you were sitting at the door of the room, what you were thinking in your heart was whether to leave her there?"

Tang Lu turned her head to avoid his question and did not answer.

"And at that time, Xu Yapei is very likely to wake up, she may cry, struggle, and call your mother..." Shen Junci's voice was very soft, not harsh.

But these words suddenly pierced through Tang Lu's defense like a sharp spear point.

Her body suddenly trembled: "Don't, don't say it..."

Shen Junci did not let her go.

He took out a frontal photo of Xu Yapei's corpse and pressed it on the table: "This is what you don't want to see when you recognize the body today. Your daughter looks like now."

In the photo, the withered corpse has an almost unrecognizable appearance.

Tang Lu didn't want to look, but she still saw something out of the corner of her eye. The withered corpse made it difficult for her to connect with her daughter.

Tang Lu's head began to throb and throb, and she seemed to hear Xu Yapei's cry again.

The voices intertwined and overlapped, getting louder and louder.

"Mommy mommy……"

These two words pierced through her head like a magic sound.

When she was a child, she would pull a disobedient child into the room, and the child would cry and yell loudly.

And a year ago, when Xu Yapei woke up, she also made such a cry. She kept beating and kicking the door in front of her: "Mom, I was wrong, let me out quickly..."

"Mom, I don't dare anymore, please forgive me. I dare not lie to you again!"

"Mom, please, I'm going to die!"

At first she was begging, but when she found out that her mother would not open the door, she started cursing and cursing.

She talked about her childhood misfortune and everything she experienced later.

She screamed and cried in despair.

The voice echoed in the empty amusement park.

For so long, no matter how Tang Lu pretended to be nothing, the shrill cry was still imprinted in her heart.At that time, she was sitting on the chair by the door, feeling helpless in her heart.

Tang Lu's back could no longer be straightened, and her body shrank into a ball.

This became the final blow that crushed Tang Lu, her hard armor cracked and shattered into pieces.

"I have always wanted to give them the best, but I didn't expect it, I didn't expect it..." Her tears flowed down, choked up, and said the second half of the sentence, "I didn't expect it, that would make the She died."

Shen Junci asked her: "So, when you locked her in, you already found out that she was alive?"

"She is so disobedient. I originally thought that I should lock her up for a while and let her suffer. I also thought about whether I should let her out...but then she started scolding me like crazy, and I I left cruelly. When I went back the next day, there was no sound inside."

Tang Lu finally admitted that she killed her daughter with her own hands.

Her shoulders trembled, and an unprecedented gaffe appeared on her body.

Finally got the most important testimony.

Even if Tang Lu later retracted the confession, this video will be used as evidence to allow the judge to make a more correct judgment.

Gu Yanchen looked at Tang Lu, then looked up at Shen Junci.

Shen Junci lowered his head, packing up the test results and reports, under the light, his skin was particularly pale.

The one-night interrogation finally came to an end. Tang Lu and Xu Ziyue were detained separately, waiting to be transferred to the detention center tomorrow morning.

Gu Yanchen waited for Shen Junci to leave work together as usual.

In the car, Shen Junci hugged his little train, and the two remained silent, as if they were still immersed in the previous case.

The difference between the happiness and misfortune of the original family is so great that it can change the trajectory of a person's life.

Those unfortunate children may not be able to heal childhood trauma in their entire lives.

When I was young, I may feel that I can escape when I grow up, but its impact is like an empty room with a closed door, which will attack and trap people to death after many years.

Reconciliation is just a good wish.

But anyone who has experienced it knows it.

Forever, there is no way to reconcile.
