Lu Weiwei had actually said everything Gu Chen wanted to say.

But Gu Chen still knew that if this was really the case, what was the kidnapping letter about?

The kidnapping letter, which had more than a hundred similarities with Yao Xin's mother's handwriting, obviously could not have been written by a little boy.

There is also a basement, where various divine operations are formed.

Let alone children, even adults may not be able to distinguish it clearly after seeing it.

If the cause and effect of all this may be caused by the dragon fruit, what happens next?

Yao Gang said that he had been sleeping, which was obviously a lie.

Could it be that Xiao Zhengtai's mental quality can be so strong?

He killed his biological sister by mistake, and still showed excitement and seemed indifferent to the death of his sister Yao Xin?

That seems crazy, doesn’t it?”

"Senior Sister Lu." Gu Chen also looked at Lu Weiwei and said what he was thinking: "Your previous reasoning was correct, but it also had flaws."

"Flaws...flaws?" Lu Weiwei was confused.

Gu Chen nodded and said: "Correct logical reasoning can prove the answer based on clues, but there are several questions here that are completely impossible to complete by Yao Gang."

"Is it the kidnapping letter and the disguise in the basement?" Officer Wang quickly answered.

"That's right." Gu Chen walked up to the two of them and continued: "Senior Brother Wang, Senior Sister Lu, I have always had doubts about Yao Xin's death. Many evidences point to her family."

"But this is completely unreasonable, because there is no motive for killing. Why would the family kill their cash cow daughter? But it is different now."

"Is it because of Yao Gang?" Lu Weiwei said.

"That's right." Gu Chen nodded happily and said, "That's Yao Gang."

"Because Yao Xin's death was most likely caused by Yao Gang's wrongful killing, and it was also very likely because Yao Xin's mother wanted to protect her son."

"So after Yao Xin's skull was cracked, she continued to strangle Yao Xin's neck with a rope, creating the illusion of being strangled to cover up Yao Gang's crime."

"And Yao Xin's mother can also clean up the flashlight that Yao Gang used, because children don't understand these things. Once clues are left, it is likely to be discovered by the police. These are not things that children should understand."

"That's right." Officer Wang also agreed with Gu Chen's opinion and said directly: "This kind of trick of cleaning up traces and pretending to be a scene in the basement can only be done by adults. Children don't understand it at all."

"And the kidnapping letter." Gu Chen also breathed a sigh of relief at this moment and said: "Before, I could only judge the author of the letter 50-50."

"But there's no need for it now. I can definitely conclude that this kidnapping letter must be a play put on by Yao Xin's mother to protect her son Yao Gang after moving her daughter into a small room in the basement."

"But she never expected that Yao Xin still had signs of life at that time, but they were very weak."

"It turned out that when she strangled Yao Xin's neck with a rope, Yao Xin died of suffocation. This is why forensic doctor Liu said he died of suffocation."

"No...that's right." He was also fascinated when he heard it, but Gu Chen suddenly called her name. Forensic doctor Liu immediately said: "The little girl did die of suffocation. She suffered severe head injuries before, and she may be brain dead at most."

"That means Yao Xin's death was caused by Yao Gang and his mother together?" Officer Wang was shocked, as if his three views at the moment were overturned.

Seeing that everyone was in disbelief, Gu Chen continued: "I can surmise that after completing these operations, Yao Xin's mother felt panicked."

"So she broke the window to create the illusion of being kidnapped by an intruder, then went back to the living room and started writing the essay in her notebook."

"In order to cover up her handwriting, Yao Xin's mother deliberately made drafts to practice, destroyed four sheets of draft paper, and then called the police."

Lu Weiwei snapped her fingers and said, "Yes, that should be it. This can also explain why the kidnappers had to draft the kidnapping letter when they wrote it."

"Because Yao Xin's mother wanted to deliberately conceal her handwriting at that time, she used a writing method that she was not very good at. But even so, Junior Brother Gu was able to find 100 similar places."

Forensic Doctor Liu also said thoughtfully: "Yes, it is almost impossible to temporarily change your handwriting, because personal habits and handwriting methods have been honed over decades.

Just making temporary changes is more difficult than reaching the sky."

After thinking about it, Forensic Doctor Liu added: "But according to Zhao Chen's reasoning, Yao Xin's mother is really a terrifying person. She can create such an illusion in a short period of time, which ordinary people cannot do."

"There must be other breakthroughs." After Gu Chen thought for a moment, he suddenly remembered forensic doctor Liu's previous explanation of DNA, so he asked again:

"By the way, Forensic Doctor Liu, you said before that you found Yao Xin's DNA on Yao Xin's pants. Whose DNA does it belong to?"

"I'm still asking the assistant to test. The results should be available soon." Seeing that Gu Chen was too concerned, Forensic Doctor Liu added:

"But I guess there won't be too many clues, because if it is left by Yao Xin's family, it doesn't mean anything. If it is the DNA of an outsider, it will be troublesome."

Officer Wang pulled up his stool, spread his hands and said helplessly: "Then what else can we do? We can only continue to wait."

So everyone waited together in the waiting room for nearly an hour. At this time, the forensic assistant came to hand over the report to Forensic Doctor Liu.

"How is it?" Forensic Doctor Liu asked after receiving the test report.

The forensic assistant said: "According to our several verifications, the results show that the DNA remaining on the deceased's pants was not left by her family at all."

"Left by a stranger?" Lu Weiwei opened her mouth in surprise: "Oh my god, is there anyone else among them?"

"It's over, it's over." Officer Wang was also quite disappointed, feeling that the little sign he had just seen seemed to have been extinguished by this damn DNA.

This chapter is not finished yet, please click on the next page to continue reading the exciting content! Forensic Doctor Liu also said with a headache: "It seems that it is not just Yao Xin's family members who are involved, but there seem to be other accomplices?"

While everyone was discussing heatedly, Gu Chen was still leaning against the corner, carefully recalling the scene.

"All the clues basically point to Yao Xin's family. However, when Yao Xin was killed, her clothes were in a mess, but the remaining DNA did not belong to Yao Xin's family. What should we do?"

Seeing that Forensic Doctor Liu was still confirming with his assistant, Gu Chen sighed and used his expert memory to start thinking about DNA-related knowledge.

Gu Chen had read a lot of books before, including some about DNA conclusions. After thinking over and over a lot of arguments, Gu Chen suddenly opened his eyes.

Seeing that Gu Chen was a little abnormal, Lu Weiwei hurriedly came over and asked him: "Junior brother Gu, everyone was discussing just now, but you are the only one who is thinking quietly here. Have you made any new discoveries, or a new breakthrough?"

"Is there such a possibility..." Gu Chen suddenly raised his head, looked at everyone in front of him and said, "Maybe we were just misled by the DNA on Yao Xin's pants."

"Misled by...?" Officer Wang became more and more confused as he listened, and quickly asked Gu Chen: "Why did you say that?"

Gu Chen said: "Because this stranger's DNA is most likely the DNA of a clothing manufacturer. Isn't it possible?"

"Eh?" After being reminded by Gu Chen, forensic doctor Liu immediately had an idea and said: "It's very possible. It might actually be the DNA of a clothing manufacturer."

"But..." Forensic Doctor Liu turned to look at Gu Chen and continued: "But everything must be verified. If we can't prove that this stranger's DNA has nothing to do with the case, then our workload will be huge."

"This is easy to handle." Also considering that Liu Forensic Doctor has always been famous for his skills, any possible conditions need to be verified, so Gu Chen said directly: "Otherwise, let's buy some random clothes and see what's on these new clothes.

, will some strangers’ DNA remain?”

"Hey, I think it will work." After hearing Gu Chen's suggestion, Lu Weiwei was the first to agree: "Just in time, I'm going to buy some coats, so leave this job to me."

"That's okay." Seeing Lu Weiwei volunteering, Officer Wang immediately pointed to the street outside the window and said:

"When you go out of the city bureau, turn right, then turn left and keep driving until you reach the business district. You can ask Gu Chen to drive you there, that's almost enough. The key is to verify Gu Chen's statement. Don't treat it like shopping."

"Look what you said." Lu Weiwei also smiled: "Of course I will make a quick decision. Forensic Doctor Liu still needs to test the results. Don't worry, I will be back soon."

Suddenly buying clothes can become a task. This is the first time Lu Weiwei has encountered it.

However, Lu Weiwei basically doesn’t have any bad habits like shopping.

Also in a hurry, Gu Chen drove the police car directly to the side of the road.

The two of them wore police uniforms at the same time and walked into a sports brand store together, instantly making the store clerk envious.

Several female shop assistants suddenly started talking quietly.

"Oh my god, driving a police car to go shopping, this policeman is so cool."

"Does this count as private use of the bus? The two of them are still wearing police uniforms. They should be at work at this time, right?"

"Perhaps I'm just passing by and buying some clothes for a business trip? Aren't there many salesmen on business trips who came to our store to buy clothes before? Many of them went to the north to buy some thick coats temporarily."

"Anyway, my attention is on that handsome policeman. Are what you said important? It doesn't seem to be important."

"Haha, then I have to go over and say hello. Maybe I can even ask for my phone number as a member."

A tall female clerk immediately straightened her hair in the mirror and then came directly in front of Gu Chen and Lu Weiwei.

"Are you two buying clothes? Couple clothes or something?" the female clerk asked.

"Oh no, I don't buy it, she does." Gu Chen pointed at Lu Weiwei and said.

The female clerk raised her lips, turned around and asked Lu Weiwei: "Excuse me, this female police officer, what kind of clothes do you want to buy? We have down jackets, casual jackets, and sports suits here..."

"Just the size according to my figure." Before the female clerk could finish her words, Lu Weiwei directly interrupted: "This, this and this, please pack them for me."

"Ah?" The female clerk was stunned for a moment. After selling clothes for so many years, she has never seen a girl buy clothes like this. She just glanced at them and packed them up, or even bought three pieces at a time?

This is different from the female customers I met before. If every female customer could be as generous in shopping as Lu Weiwei, it feels like all the store employees would wake up smiling every day.

"You...can you apply for a membership card? Membership cards offer discounts and you will get points for future purchases. The points can be used for a lot of discounts. Can I fill out a form for you?" The female clerk looked at Lu Weiwei with bright eyes.

Lu Weiwei waved her hand: "No, just wrap it up for me. I'm in a hurry."

The female clerk was stunned again and quickly asked other clerks to help get the clothes.

As a result, Lu Weiwei carried three bags of clothes and drove away with Gu Chen without even asking for an invoice, leaving only the clerk in a mess.

Everyone was still waiting, and Officer Wang even played with some pesticides.
