Yao Gang seems to be a bear child in the mouth of the nanny, so the nanny's evaluation of Yao Gang is not high.

Like most families with two children, Yao Xin's parents don't seem to be doing a good job of balancing the pampering between their two children.

At least it seems to Yao Gang that his parents' love for his sister Yao Xin is higher than Yao Gang's, which can easily make Yao Gang jealous.

"Have you ever done something excessive between those two siblings, such as fighting?" Gu Chen asked again.

The nanny thought for a few seconds before she said, "If you want to ask that, there really is." ”

"Let's talk about it. Gu Chen said.

"When the two siblings attended a relative's birthday party before, Yao Xin, as the little princess of the family, wanted to perform on stage, but his brother Yao Gang was stunned and cut the clothes that his sister was going to perform. ”

"Cut your clothes?" Lu Weiwei was also stunned, and said thoughtfully: "This little boy is too naughty, isn't he?

"Isn't it? The nanny also sighed helplessly: "Yao Gang made such a fuss, which led to the fact that at this birthday party, when Yao Xin was about to walk the catwalk, his suspender pants slipped off directly, which made Yao Xin very embarrassed." ”

For this reason, Yao Xin ran to complain to her parents, and her parents only blamed a few words, after all, the palms and backs of her hands are full of meat, and it is not good to blame anyone. ”

"Another time was when Yao Xin won the championship in the competition, and the family prepared a celebration banquet for Yao Xin, and specially invited a chef from a star-rated hotel, but Yao Gang went to fill urine in the cup where his sister Yao Xin drank drinks. ”

There is also the sheet on which Yao Xin sleeps, Yao Ganghui often pours some cat and puppy feces on it, and even once, Yao Xin found feces on Christmas gifts. ”

"It's too much. When Officer Wang heard this, his whole person was stupid: "This Yao Gang, he is not very old, he has done all the bad things, how can he engage in such a prank at such a young age? Especially to his sister." ”

The nanny also said: "So this child is too bearish, my parents can't cure him, as long as they don't do too much, they will let it go." ”

"I'm an outsider, just working as a nanny in his house, what can I say? After all, it's not my own child. ”

"If this is my child, I have to hang him up and beat him, but Yao Xin is still quite qualified, and he doesn't care about Yao Gang every time. ”

But the more he didn't care about Yao Gang, the more this kid liked to play pranks, and Yao Xin was scared and cried several times by Yao Gang pretending to be a ghost. ”

"Anyway, the relationship between the two siblings is not too good, and they basically spend their time in fighting. ”

Yao Xin often competes on major catwalks because of her agent Wu Qian, and she is rarely at home, so the two siblings don't actually stay together for a long time. ”

The nanny also explained Yao Gang's personality and the relationship between the two siblings to the police in 1510.

After hanging up the phone, Officer Wang suddenly fell silent.

Seeing this, Lu Weiwei hurriedly asked Officer Wang, "Lao Wang, do you have any ideas?"

"I have a lot of ideas. Officer Wang looked at Lu Weiwei and said, "This Yao Gang, if I hadn't heard what the nanny said before, maybe I didn't have any thoughts about him, but now it's different, I feel that Gu Chen's previous speculation is reasonable." ”

"Just imagine why his sister was so happy and excited when his sister was killed, and he didn't seem to care. ”

"This is too indifferent and ruthless for a brother, right? This is also his sister, it can be seen that this little Zheng Tai Yao Gang seems to have no family affection for his family. ”

Of course, Officer Wang said this completely out of feeling, after all, he heard so much about Yao Gang's bad deeds on the phone.

To be honest, if Yao Gang was his own child, Officer Wang would have the same idea as the nanny, that is, to hang up and teach a lesson.

Even if you cut off the costume of your sister's performance, you can also get some cat and dog feces on your sister's gifts and sheets, normal people don't do this.

It can be seen that Xiao Zhengtai Yao Gang is not a normal person, but a spoiled bear child.

At least the son is not the fault of the godfather, and the first person to be held accountable should be Yao Gang's father.

Looking at Gu Chen, who was thinking, Officer Wang asked him, "Gu Chen, what do you think?"

"I have the same opinion as Senior Brother Wang. Gu Chen looked up at him and said with some doubts: "But from this alone, it is difficult to conclude that there is any key connection between Yao Gang and Yao Xin, at least the motive for the murder is not clear." ”

"You mean......" Lu Weiwei said suddenly.

Gu Chen said: "The nanny's words at least show that the relationship between the two brothers and sisters is not very good, Xiao Zhengtai Yao Gang is jealous of his sister Yao Xin, but it is not easy to conclude based on this alone." ”

"Because even if Yao Gang is the murderer, the fake scene in the basement, I think that with Yao Gang, the little Zhengtai, he can't complete such an operation at all. ”

"And think about it, that kidnapping letter was obviously written by an adult, what does it have to do with Yao Gang?"

When Gu Chen said this, Lu Weiwei, who originally felt a breakthrough, instantly became even more confused.

"It's not that either, I feel like this case is a bit cumbersome. Lu Weiwei also crossed her waist and said a little impatiently: "If you follow the previous reasoning, maybe Yao Xin's mother is more likely, but Yao Xin's brother Yao Gang is also a little abnormal." ”

"But the most important thing is, what is their motive for killing? That's the key. ”

Seeing Lu Weiwei's tirade, Officer Wang also said helplessly: "Let's not talk about this for now, let's see what new discoveries there are on Forensic Doctor Liu's side later, right, Gu Chen?"

Officer Wang turned his head to look at Gu Chen.

Gu Chen nodded: "Okay, just do it according to Senior Brother Wang." ”

Several people continued to wait......

It was also after more than ten minutes that Forensic Doctor Liu came out of the testing room and came directly to the waiting room.

Seeing Forensic Doctor Liu enter the house, everyone stood up at the same time and came to Forensic Doctor Liu's side together.

"How is Forensic Doctor Liu?" Gu Chen took the lead in asking.

Forensic Doctor Liu hesitated for a moment and said, "The test results are already available, the time of the little girl's death should be yesterday, almost two or three o'clock in the afternoon, and the cause of death is preliminarily determined to be suffocation." ”

"What about the blunt object hitting the head?" Gu Chen asked.

"Because the little girl was hit in the head first, causing the skull to almost split in two, I concluded that the little girl should have been brain dead at that time. ”

However, the murderer was afraid of revealing his modus operandi, or because the murderer thought that the little girl was dead, so he strangled a strangulation mark on the little girl's neck, which caused the little girl to suffocate to death. ”

"What...... What? The little girl was brain dead before, and then she was strangled to death?" Lu Weiwei's eyes moistened when she heard this.

Although as a police officer of the criminal investigation team, Lu Weiwei has never seen any winds and waves, but this little girl is the only one who took a photo with herself a few days ago.

Lu Weiwei has even liked this little girl since then, and she feels really a sensible child.

Although he is already well-known and has a good performance on the international catwalk, Yao Xin gives Lu Weiwei the feeling that she is the kind of low-key good child.

But the good boy was suddenly gone, and he was still beaten in two with a flashlight, and then strangled to death with a rope.

Thinking of this, Lu Weiwei was in a bad mood.

"Senior Sister Lu. Gu Chen also saw that her eyes were moist, and hurriedly handed her a napkin.

"Thank you. After Lu Weiwei took it, she dipped the corners of her eyes and said: "I think this murderer is too cruel and cunning, but it seems that it is difficult to judge who the murderer is now based on these clues alone." ”

"Oh yes. At the same time as Lu Weiwei threw out her doubts, Forensic Doctor Liu said: "After technical testing, I found that the little girl had eaten dragon fruit in the time before she was killed. ”

"Dragon fruit?" Gu Chen's eyes lit up, and he hurriedly said, "By the way, when we were searching for clues earlier, I found that there was a plate of dragon fruit in Yao Xin's refrigerator, and there seemed to be uneaten dragon fruit in it. ”

"That's right. Lu Weiwei suddenly said: "Yes, I also found out, we should check that thing, but I didn't know at the time." ”

"And. Seeing that everyone instantly ignited their wits, Forensic Doctor Liu said again: "I extracted a DNA from the little girl's pants that is not the little girl herself, I want to ......."

"You mean...... It is very likely that this is the murderer's DNA?" Gu Chen hurriedly asked him according to the ideas provided by Forensic Doctor Liu.

Forensic Doctor Liu nodded: "That's right, that's what I meant, because the little girl's clothes are messy, I think she seems to have been torn before she was killed, so this DNA is very important." ”

"I have to know who in the little girl's family matches this DNA, and I need to collect other people's DNA for investigation. ”

"This is very simple, we can go to Yao Xin's house again, it happens that the little girl eats dragon fruit, we can also investigate it and see if we can find new clues." ”

Gu Chen had long been suspicious of Yao Xin's family.

The reason is simple, if it was really an outsider who committed the crime, for ransom, then he would not casually throw the body in the basement of the victim's home.

Because once it is discovered that the person is dead, then his ransom will be lost.

Regardless of whether you tear up the ticket or not, at least you have to disguise it as if the kidnapped person is still alive, right?

Several people hit it off, so they prepared to return to Yao Xin's house and make another argument on the evidence they already had.

Forensic Doctor Liu also worked tirelessly, followed closely with the forensic assistant, and followed the third criminal investigation team to the villa in the western suburbs.

At this moment, the Yao family is still immersed in the grief of losing Yao Xin, and they also see the police coming again.

Yao Xin's father was the first to walk out of the door and hurriedly asked, "Officer Gu, has my daughter's investigation progressed?"

"There has been some progress. Gu Chen first comforted him to stabilize Yao Xin's father's emotions, and then said: "But there is still some evidence collection work that requires Yao Xin's clues. ”

"Of course. Yao Xin's father agreed very happily, and said directly: "As long as you can find the murderer who killed my daughter, you can let me cooperate as much as I want." ”

"We need to do another search of your home. Lu Weiwei also walked over with the information book and said, "Also, I need the DNA of all of you." ”

"Yes. Yao Xin's father didn't bargain, and his answer was quite refreshing.

Gu Chen smiled with satisfaction: "Mr. Yao, don't worry, it may not be long before the murderer who killed Yao Xin can be found." ”

Yao Xin's father waved his hand: "I don't care how your police investigate, where you should cooperate, I will fully cooperate, I only want the truth, I want justice for my daughter......"

Yao Xin's father has been talking there for a long time, but time is running out, Gu Chen, Lu Weiwei and Officer Wang don't have time to listen to his complaints, and Forensic Doctor Liu doesn't have time.

So, Forensic Doctor Liu collected DNA from Yao's family and collected all people's fingerprints by the way.

Gu Chen, on the other hand, put on white gloves and came directly to Yao Xin's kitchen.

opened the refrigerator, and when he saw the uneaten dragon fruit on the plate, Gu Chen immediately breathed a sigh of relief, and then took out the dragon fruit in the refrigerator and recorded the fingerprints on the plate.

After some operations, Gu Chen took advantage of the moment when Forensic Doctor Liu was collecting, and came to Yao Xin's mother and asked, "Can you be sure that your son Yao Gang had been sleeping when his daughter was kidnapped?"

was also asked again by Gu Chen, Yao Xin's mother was suddenly stunned, but quickly responded: "Of course, Yao Xin has been sleeping in the room from the time she was kidnapped by the kidnappers to the time her father and I arrived, and he didn't know anything about the outside at all." ”

"Really?" Gu Chen looked at Yao Xin's mother with sharp eyes.

Yao Xin's mother was also a little afraid of such eyes, but after looking at each other for a short time, Yao Xin's mother still said with great certainty: "That's right, these are true, Yao Gang has been sleeping, and he doesn't know anything." ”

"Yao Gang. Gu Chen then turned his head to look at Xiao Zhengtai Yao Gang and beckoned him to come over.

Yao Gang didn't seem to be too willing to cooperate, so he came to Gu Chen's side half-pushed and asked, "What are you doing?"

"Did you sleep all the time when my sister was kidnapped yesterday? Or did you wake up and see something, and then fall asleep again in a daze?"

Xiao Zhengtai seemed to be stunned by Gu Chen's question, stretched out his right hand and scratched his head, then turned his head to look at his mother, and then nodded: "Yes, I've been sleeping, I don't know what happened to Yao Xin." ”

At this time, Lu Weiwei took the remaining dragon fruit and put it on the table with several other fruit plates in the refrigerator, and asked, "Did Yao Xin and Yao Gang both eat dragon fruit yesterday?"

"No...... I don't know. Yao Xin's mother shook her head and said thoughtfully, "Did they eat? I don't remember much." ”

"Then is this dragon fruit from yesterday?" Gu Chen asked again.

Yao Xin's mother nodded: "That's right, it was yesterday." ”

"Then can we bring these fruits back to investigate?" Gu Chen said.

Yao Xin's mother still nodded: "But ...... Yes, you can take it. ”

"Thank you. After Gu Chen finished speaking, with Lu Weiwei's cooperation, the fruit in the refrigerator, along with the plate, was put into the evidence bag.

Forensic Doctor Liu also completed the operation at this moment, and was about to pack up his things, and Officer Wang was helping.

And Gu Chen and Lu Weiwei have also put the evidence in the evidence box.

Because Yao Xin had eaten dragon fruit before he was killed yesterday, these dragon fruits were the key.

Of course, taking the other fruit bowls with you is also the starting point of not missing any clues.

Everyone still returned to the technical section of the city bureau.

This time, Forensic Liu operated more quickly, and soon detected Yao Gang's fingerprints on the plate containing dragon fruit.

Turning his head to look at everyone, Forensic Doctor Liu said, "The fingerprints belong to his brother." ”

"Sure enough, it's Yao Gang's, but hasn't Yao Gang been sleeping? Could it be that Yao Gang was also there when Yao Xin was eating dragon fruit?" asked Lu Weiwei.

Gu Chen glanced at Forensic Doctor Liu and asked, "Forensic Doctor Liu, is there only Yao Gang's fingerprints on this plate, and what about their parents' fingerprints?"

Forensic Doctor Liu shook his head and said, "There are fingerprints of Yao Xin's parents on other fruit plates, but only this dragon fruit plate has the fingerprints of Yao Gang and Yao Xin. ”

"This shows that Yao Xin and Yao Gang have both eaten dragon fruit, if you look at the information you have learned before, it seems that the two brothers and sisters are fighting for everything, and it does not rule out the fact that the two children are competing for dragon fruit to eat. ”

After listening to Forensic Liu's detection and reasoning, Gu Chen suddenly set his eyes on the flashlight of the transparent forensic bag.

He immediately picked up the flashlight and asked, "What about the flashlight? If it was a little boy, would his strength be able to smash Yao Xin's head into such a serious injury?"

Forensic Doctor Liu nodded and said, "I have asked my assistant to do an experiment before, and I have re-simulated whether the little boy can use a flashlight to do that kind of damage. ”

"Experiments have proven that it is completely possible, and it does not require a lot of force, and the angle and force of the injury are very consistent. ”

"That is to say......" Gu Chen's right fist smashed on his left palm: "That is to say, Xiao Zheng is too Yao Gang, it is completely possible to create such an injury, and the scar on Yao Xin's head is very likely to be caused by Yao Gang?"

"Hiss......" also heard Gu Chen's reasoning, Lu Weiwei couldn't help but gasp and said, "This ...... This is too terrifying, isn't it? What kind of hatred does my brother have for my sister, I want to use a flashlight to smash Yao Xin's skull like this, and this is almost split into two, and if you don't die, you have to be brain dead. ”

Lu Weiwei suddenly felt that the world of children did not seem to be so simple.

At least Xiao Zhengtai Yao Gang seems to be the kind of bear child who doesn't play lightly or heavily.

Afterwards, Lu Weiwei looked at Gu Chen and gave her reasoning: "Senior Brother Gu, do you think the situation will be like this, this plate of dragon fruit was cut and made by Xiao Zhengtai Yao Gang first, but Yao Xin came over and found that her brother was eating, so she also ate a few pieces." ”

As a result, he was discovered by his brother Yao Gang, Yao Gang warned his sister not to let her eat, but her sister Yao Xin didn't listen and continued to eat, so Yao Gang picked up the flashlight on the table and slammed it at her head. ”

Yao Xin fell unconscious, her skull was almost split in two, and she was brain dead. ”

"Then moved my sister to a small room in the basement and created the illusion of the scene before, what do you think of Senior Brother Gu?"

......
