afternoon.

Jiangnan City Furong Branch, Criminal Investigation Group Three Office.

Yuan Shasha was at the printer, organizing the documents sent by forensic assistant Gao Chuanfeng into a volume, binding them with a binding machine, and quickly sent them to Gu Chen's desk.

"Brother Gu, the evidence test on Zhu Lei's family has come out. Also, the Municipal Bureau's Technical Section has done a DNA test on Zhang Lan's father. The results are as you speculated. It's the same as the cleaned blood stain DNA."

It matches, this is Zhang Lan’s bloodstain.”

"What about the bloody cloth? Have you detected Zhu Lei's blood?" Gu Chen raised his head and asked again.

"Yes, they are all there." Yuan Shasha quickly opened the documents on Gu Chen's desk to the second page, then pointed to a piece of content and said, "Look here, everything is explained."

"Forensic doctor Liu and assistant Gao Chuanfeng have collected Zhu Lei's blood. According to repeated comparisons between Zhu Lei's blood and the bloody cloth strips, the results are the same. Although there are some blood stains of Zhang Lan among the blood stains,

Some of them belong to Zhu Lei."

"Great." Lu Weiwei turned around excitedly and said, "Junior Brother Gu, with these evidences, we are not afraid that Zhu Lei will not explain clearly."

"If he had no evil intentions, why would he sell the bloody sofa bed? This shows that there was a lot of blood on the sofa bed and he had no choice but to deal with it."

"That's right." Gu Chen agreed very much with Lu Weiwei's opinion. He leaned his hands on the back of his head and said relaxedly, "I guess this bloody piece of cloth is just a damaged piece of cloth on the sofa bed."

"After Zhu Lei committed the murder, perhaps it was because the cloth strip was stained with too much Zhang Lan's blood, and when he was handling the sofa bed, he accidentally wiped the blood stain with the fallen cloth strip."

"But in order to prevent others from discovering the flaw, I temporarily hid the strip of cloth behind a cardboard box in the crawl space."

"And I bet he was probably going to put the bloody strip there and deal with it later, but then he forgot about it."

"Yes." Officer Wang came to everyone with wolfberry tea and said: "I agree with Gu Chen's opinion. After all, you think, he, Zhu Lei, has even wiped the blood stains on the floor tiles and the blood stains on the tiles carefully.

."

"He even flushed all the blood residue into the sewer. If he could do it so meticulously, it means that Zhu Lei also wanted to deal with all the evidence at the scene, but he forgot to sell the sofa bed and the paper hidden in the crawl space.

The little strip of cloth on the back of the box.”

"That's right." Lu Weiwei listened to Officer Wang's words and nodded silently: "And the DNA we extracted from the bloody cloth once again confirmed that the DNA in the blood was consistent with that of the victim Zhang Lan.

Father matches."

"And the most important thing is that we also found traces of Zhu Lei's blood. With all this evidence, I don't believe that Zhu Lei has not pleaded guilty."

"These are enough." Gu Chen put the information on the table, paused, and asked Yuan Shasha: "Xiao Yuan, where is Zhu Lei now?"

"We're waiting in Interrogation Room 2." Yuan Shasha said.

"Let's go to Interrogation Room 2." Gu Chen put the information under his arm, picked up the police hat on the table and walked out.

When Yuan Shasha and Lu Weiwei saw this, they also picked up their belongings and trotted behind them.

Only Officer Wang was the only one who followed everyone, whistling like a seasoned veteran.

…

…

Interrogation Room 2.

Zhu Lei, who was sitting in the interrogation chair, had been mentally disturbed since he was brought here.

Gu Chen investigated the evidence collected at the scene and sent it to the Municipal Bureau's Technical Section for inspection.

Zhu Lei knew that he would come back sooner or later.

Looking at the Peppa Pig tattoo on his arm, Zhu Lei felt like he was a pig waiting to be slaughtered.

Suddenly he heard footsteps outside, and Zhu Lei subconsciously raised his head.

Seeing the door of the interrogation room opened, Gu Chen, Lu Weiwei, and Yuan Shasha walked in talking and laughing.

It can be seen that the moment they saw Zhu Lei, everyone's expressions immediately became serious.

Gu Chen sat in the middle of the interrogation table.

Lu Weiwei chose to sit on the right side.

As for Yuan Shasha, as a rookie trainee police officer, she wisely set up the tripod in the room, set up the camera and adjusted the switch, and then hurriedly came to sit on Gu Chen's left side.

Officer Wang came last, closed the door, sat on the side next to Yuan Shasha, and threw the documents heavily on the table.

This action made Zhu Lei tremble in fright.

Obviously, older comrades are better than young police officers at putting pressure on those being interrogated.

Just a small gesture can let the other person know that things are not that simple.

"Tell me your name, age, and ID number." Gu Chen opened the transcript and asked.

Zhu Lei swallowed a mouthful of saliva and then said weakly: "I...my name is Zhu Lei. I am 29 this year. My ID number is..."

According to Gu Chen's prompt request, Zhu Lei disclosed his personal information.

After Gu Chen wrote some words, he also took the inspection document faxed from the Technical Department of the Municipal Bureau in his hand and said:

"I just got this test report. All the evidence shows that it was you who killed Zhang Lan in the rental house."

After putting down the test report, Gu Chen took the transparent evidence bag containing half of the bloody cloth strip in his hand and said, "The blood stains on this cloth strip belong to both Zhang Lan and you."

"And this piece of cloth is obviously from the sofa bed in the basement on the first floor, but you said you didn't know there was blood on the sofa bed. It's just nonsense."

Seeing that Gu Chen was a little angry, Zhu Lei was too frightened to raise his head.

"And..." Lu Weiwei on the side continued to add: "We did experiments with fluorescent agents in the living room on the ground floor of your house. Of all the fluorescent spots, only the sofa bed was vacant.

There was no blood and the outline was very obvious."

"This is enough to prove that you are a liar. In fact, you are the murderer of Zhang Lan. What else do you have to say?"

"I..." Zhu Lei looked a little desperate at this moment.

Although he has various tattoos all over his body, he dresses and looks like a social person, but under the bombardment of various evidences, Zhu Lei seems somewhat unable to refute.

Seeing the four striking words "Leniency for those who confess, severity for those who resist" on the back of Gu Chen, Zhu Lei looked sad and nodded weakly:

"No...that's right, I killed Zhang Lan, but I was only protecting myself. If I didn't kill her at that time, she might have killed me. I was completely helpless. Who knew she could be like this?

people."

Gu Chen frowned, glanced at Lu Weiwei beside him, then turned around and asked again: "If you want to clarify, what exactly happened to you at that time?"

"That's it, Officer Gu." Zhu Lei sniffed and then regretfully said:

"I lost a lot of money at the mahjong parlor that day. Not only that, I also owed a lot to others, so I... I went home to Zhang Lan and asked her for some money."

"But Zhang Lan was having conflicts with me at that time. During this period of time, she and I were arguing almost every day, so I tried to reason with her. I said don't think I don't know that she was dating other men in private at the same time.

matter."

"But it's okay not to mention it. It seemed to irritate her. I don't know where she pulled out a machete. Oh, by the way, it's the one you found at the scene."

"Actually, that knife is not mine, but Zhang Lan's."

"Not only did she have a machete, but she also had saws, electric drills, various scalpels and tweezers, the same things they used to dissect frogs in the laboratory at the School of Nursing. She brought almost all of them home."

Gu Chen frowned and asked Zhu Lei: "Does Zhang Lan have a hobby of torturing cats?"

"Yes, yes, she has a hobby of torturing cats. She killed all the dead cats buried in the yard."

When Gu Chen heard this, he couldn't help being surprised. He exchanged looks with his colleagues and seemed to understand.

"Zhang Lan's online name is..."

"It's called Nuan Mao, and she seems to have a cat abuse group. He said he used her trumpet to open it." Before Gu Chen could finish speaking, Zhu Lei had already explained everything.

"No wonder she didn't live broadcast on time that day. Did she waste time chatting with us on the basketball court?" Officer Wang also felt a sense of fear.

All the timelines, and the dead cat in the yard, seemed to explain everything.

"I don't believe it either. How could such a gentle girl have such a hobby?" Zhu Lei also raised his hand, wiped his forehead with the back of his hand, and then said:

"When I met her, she was not like this. She was very gentle. But later I discovered that it was all an act."

"I was deceived by her gentle appearance on the basketball court of their school. After getting along with her for a while, I realized that she has an irritable personality and can become violent at every turn."

"And you know, Officer Gu, if I don't agree with her, she will threaten me and say that she will dissect me like those dead cats. I was so scared that I quickly hugged my vital parts, for fear that she would be there."

When I am asleep, let me cut off the queen."

"So scary?" Yuan Shasha couldn't believe it, thinking that she was completely different from the Zhang Lan she saw on the basketball court that day.

How could a girl who blushes easily when she talks could be a cruel cat abuser?

Yuan Shasha glared at Zhu Lei and warned: "If we know you are lying, you will know the consequences."

"Don't dare, comrade police, their cat abuse is a collective industry chain. She and the other administrators in the cat abuse group are all from nearby schools. I have even met them."

"If you want to know if it's true, I can tell you the information about those people now. You can see if I'm lying."

After Gu Chen made eye contact with Lu Weiwei, Yuan Shasha and Officer Wang, he said: "Okay, even if what you said is true, why did you kill Zhang Lan so cruelly? You haven't explained clearly yet."

"It's unfair, comrade policeman." Zhu Lei said in frustration: "I asked her for money, but she didn't give it. The two of them had a big quarrel, and she wanted to chop me with a machete."

"I was so scared that I almost peed. This was a real guy. After I dodged a few stabs, I picked up a stool and threw it at Zhang Lan."

"But who knew that she used too much force and the stool hit the blade of the knife in her hand and bounced back, accidentally injuring her carotid artery."

"I was terrified at the time. The whole room was splattered with blood. Zhang Lan was sitting on the sofa bed. There was no movement after a while."

"I knew at the time that I was in trouble, but I was also afraid. I didn't want to go to jail, so I kept doing nothing. I secretly buried Zhang Lan in the yard while the night was quiet."
