Lin Wanyu did not delay, and directly swept a shared tram and rode to the police station.

Looking at the photos stacked in front of him, Lin Wanyu's brows furrowed deeply.

"Are these all done by Lu Xiao?"

Although Gu Chi just let her see it and didn't say anything, she could guess it in her heart.

"That's right, these may be the preparations he made for the murder of his father."

Lin Wanyu shook his head and couldn't help but sigh for Lu Xiao.

"Now that the chain of evidence has become much clearer, I believe that it will not be long before the truth will come out."

Sure enough, the medical examiner took her lover's body back to the police station for splicing and testing, and found a small amount of skin debris in her fingernails.

After this discovery was announced, Gu Chi immediately thought of the wound on Chen Guifen's arm.

"Immediately compare the DNA of the skin fragments in her nail cracks with Chen Guifen's!"

At the same time, he interrogated Chen Guifen again.

"I don't need to say more about the rules, right?"

Gu Chi's eyes glanced at the decibel machine on the side, Chen Guifen immediately understood, and shook his head busily: "Comrade policeman, you believe me, what I said is true!" ”

"It's not really up to you, it's me who has the final say."

As he spoke, Gu Chi took out a stack of photos from the folder and still looked in front of her, "Take a good look, this is copied from your home computer, they are all photos of your husband and his lover, you should be familiar with it, right?" ”

Chen Guifen, who saw those photos, was like a poisonous snake that saw its prey, and her eyes flashed with a venomous light: "Of course I know!" I only found out about his dirty affair with that slut when I saw these photos in the first place! ”

"Do you know who took these pictures?"

"Didn't the two of them shoot it?"

It seems that Chen Guifen also did not know the origin of these photos.

"Have you ever seen your son do biological experiments?"

"Biological experiments?" Chen Guifen was a little puzzled, "What is a biological experiment?" ”

"It's just dissecting small animals, bloody."

Chen Guifen shook her head busily: "Impossible!" My son is quiet on weekdays, and he hasn't even brought chicken to the killing shop, so he definitely won't do this. ”

"And what are these?"

Gu Chi threw the photos of those dissected animals in front of her again.

The bloody photos made Chen Guifen's face change greatly.

"This ...... Is this a small one? ”

"That's right, it's all your son's handiwork. We found it under your son's bed, what else do you have to say? ”

Chen Guifen bowed her head gloomily, her lips trembling and she couldn't speak.

"Your son didn't kill anyone, you know best in your heart, I hope you can take the initiative to tell the truth, instead of letting me use extraordinary means."

"Team Gu!"

Ye Ziyue slammed open the door of the interrogation room, "The team member in charge of the community search has made a new discovery!" ”

"Go out and talk."

Gu Chi glanced at Chen Guifen and left the interrogation room with Ye Ziyue.

"The murder weapon that killed Lu Yi has been found! It's in the flower bed of their neighborhood. ”

Ye Ziyue laid out the floor plan of the community on the table, and marked the deceased's home and the location where the murder weapon was found.

"Where is this murder weapon...... It's in the corresponding place of their small room. ”

Gu Chi lowered his head slightly and muttered for a moment, and immediately discovered the strangeness in it.

"Yes, that's a crucial point. The first scene of the murder was in the basement of their residential building. We suspect that Lu Xiao followed his father to the basement, stabbed him with a knife in his father's body, and then carried the body to the trash can on the ground when there were few people, and we found Lu Xiao's DNA on the basement wall. ”

"Okay, you've worked hard, let's get busy first."

Gu Chi immediately thought of Lin Wanyu, and he wanted to hear her thoughts.

"The murder weapon was taken from the basement and thrown down at home?"

Lin Wanyu tilted his head and thought for a while.

"Could it be that after Lu Xiao killed someone, he wanted to go upstairs to clean the knife and stuff it into the knife holder, but found that he couldn't wash it and simply threw it downstairs again?"

"No," Gu Chi shook his head, "Lu Xiao is a very calm person, every step has been carefully planned, and he won't know that the luminol solution can react with the washed bloodstains." ”

Lin Wanyu pouted and looked at the floor plan of the community, without a clue.

"Hmm...... Is it possible that he is going to do something with this knife? ”

Lin Wanyu thought hard, and suddenly, an idea came to her mind, "Will he still use this knife to kill people?!" ”

"Murder?"

Gu Chi still didn't quite understand.

"Kill that lover? Wait until the next time you meet and then use this knife to kill? This way it won't cost two knives. ”

"That's not right," Gu Chi shook his head and slammed the floor plan on the table, "He's going to kill Chen Guifen!" ”

"Huh?"

Lin Wanyu's eyes widened, "Why did he kill Chen Guifen?" Isn't it nice to him? I don't understand. ”

"Maybe it's because the family atmosphere has been too depressed for a long time, so that his heart has been extremely distorted, so he has a grudge against every family member, so he wants to kill all his family members and then commit suicide; Maybe it's because he is afraid that Chen Guifen will find out that he killed his father when he goes home, so he wants to strike first? ”

"It's cruel......"

Lin Wanyu was a little embarrassed in his heart, "Chen Guifen probably didn't expect that the son he had been defending would want to put himself to death, which is really touching." ”

"There's no way, a murderer like Lu Xiao often leaves his feelings, including family affection, behind him a long time ago, so he can commit such a crime without scruples."

Gu Chi shook his head, and there was no trace of turmoil in his heart.

He has seen a lot of cases like this, how many children have killed their parents for money, so in comparison, people like Lu Xiao who committed crimes because of lack of love seem to be more worthy of forgiveness and sympathy.

"What about you? Is the family good to you? On a whim, Gu Chi asked Lin Wanyu on the other side.

Lin Wanyu, who was mentioned about his family situation, suddenly became anxious, and hurriedly fled the office under the pretext of going to the bathroom.

A person like Gu Chi, who seems to have a wealthy family and is pampered, would definitely look down on her if he knew what her father had done, right?

She didn't want to know the outcome yet, at least not yet.

However, Gu Chi didn't have time to dwell on this issue, and not long after Lin Wanyu left, the police officers from the technical department sent the test results of the knife.

Although the knife body has been carefully cleaned and even polished, there are still Lu Yi's blood stains and a few Lu Xiao's fingerprints on it.

The chain of evidence is complete, Gu Chi no longer hesitates, and gives an arrest warrant to Lu Xiao, Yang Zhixun, who is near the school, serves as the main force, and the net collection operation has finally begun!
