After finding the murder weapon, Luo Fei immediately called Zhao Donglai, who then ordered the arrest of Liu Wei.

Luo Fei called Sun Jun and Zhang Fan, who were monitoring Liu Wei, and asked them to arrest Liu Wei.

At nine o'clock in the evening, in the interrogation room of the criminal police team, Liu Wei was sitting on a chair in the interrogation room with his hands cuffed.

Outside the interrogation room, squadron captains Yang Su and Yang Mei, who had just received the news, had just arrived at the criminal police team.

"Luo Fei, you kid, your speed is too fast. I just went back to take a shower and eat. With such skill, you caught the murderer. You are so amazing." Yang Su The expression he looked at Luo Fei was as if he had seen something incredible.

"But okay, Luo Fei has caught the murderer. He can sleep peacefully tonight, and he doesn't have to worry about working overtime every day in the next few days." Zhang Fan said jokingly.

"How did Luo Feiqian catch the murderer?" Yang Mei asked very curiously.

"Okay, okay, Luo Fei still wants to interrogate the suspect. If you have any questions, please wait until Luo Fei's interrogation is over!" Zhao Donglai said with a smile. Just as Zhang Fan said, Luo Fei caught the murderer. I can sleep peacefully tonight. I instantly feel much more relaxed and in a much better mood.

"Captain, I'm in." Luo Fei finished talking to Zhao Dong, greeted Sun Jun, and the two walked into the interrogation room.

When Liu Wei saw Luo Fei and Sun Jun coming in, there were no expressions on their faces, as if he had known this would happen.

"You killed Jin Dayuan and his family, right? We found the murder weapon in the hotel you rented. It's useless for you to defend yourself." Luo Fei asked directly without beating around the bush.

"I didn't want to defend myself. I killed Jin Dayuan's family." What Luo Fei didn't expect was that Liu Wei directly admitted it.

"Tell me, why did you kill Jin Dayuan's family of four?" Although he was surprised, Luo Fei still asked calmly.

"I originally just wanted to kill Jin Dayuan, but I don't know why. I felt like I was possessed by an evil spirit. I couldn't control myself." Liu Wei's always calm expression became a little painful.

"What happened? Why did you kill Jin Dayuan?" Luo Fei continued to ask.

Liu Wei was silent for a while, and then said, "If it weren't for him, Huang Ying would not have had a miscarriage, and we would not have lost the child. The doctor said that Huang Ying's miscarriage caused damage to her uterus, and she will not be able to get pregnant in the future. All of this has It's Jin Dayuan's fault, if it weren't for him, there wouldn't be so many things, he really deserves to die."

Then Liu Wei told the whole thing one by one. It turned out that Huang Ying fell and had a miscarriage because Jin Dayuan lost money and went to Huang Ying's house to borrow money. However, Jin Dayuan had already borrowed a lot of money from Liu Wei and his wife, so Huang Ying didn't want to borrow it. He gave him the money, but Jin Dayuan, relying on the fact that he was Huang Ying's brother, went straight to grab Huang Ying's wallet. Upon seeing this, Huang Ying quickly reached out to stop him.

Unexpectedly, Jin Dayuan pushed Huang Ying hard in anger. Huang Ying fell to the ground without paying attention, which caused the fetal fluid to move. Huang Ying bled on the spot, but Jin Dayuan turned a blind eye and took the wallet. I hurried to the casino with the few hundred dollars in my pocket.

Huang Ying endured the pain and called Liu Wei. After Liu Wei received Huang Ying's call, he went home and quickly took his wife Huang Ying to the county hospital. However, she was still late. The doctor said that the child could not be saved, and even Huang Ying's future Neither of them could get pregnant anymore, which was a huge blow to both Liu Wei and Huang Ying.

Huang Ying did not tell the truth to Liu Wei. She only said that she fell. She was afraid that Liu Wei would lose his mind for a while and settle the score with Jin Dayuan.

Until last night, the hospital informed Liu Wei that his previous payment had been spent and he needed to pay again. Liu Wei didn't have any extra money at all, so Liu Wei waited for Huang Ying to fall asleep and went to Taohua Village overnight, hoping to Ask Jin Dayuan to get back part of the money he lent to Jin Dayuan to pay for medical expenses.

But Liu Wei didn't expect that Jin Dayuan, relying on himself as Huang Ying's brother, acted like a rogue and never thought about paying back the money. He also kept mocking Liu Wei, saying that he was blind before his sister married Liu Wei, and there would be no benefits from marrying Liu Wei. No, he even scolded Huang Ying for having no conscience. After marrying Liu Wei, she forgot about her brother and refused to even borrow some money.

While talking, Jin Dayuan accidentally mentioned that Huang Ying refused to lend him money that day, so he grabbed Huang Ying's wallet and pushed Huang Ying down. Liu Wei suddenly realized that it was Jin Dayuan who pushed Huang Ying that day, not like Huang Ying fell down by herself.

Looking at Jin Dayuan who kept mocking and cursing him and Huang Ying, he thought about Jin Dayuan causing him and Huang Ying to lose their child, and Huang Ying would never be able to get pregnant again.

Liu Wei instantly felt a surge of anger rising from the bottom of his heart. Then he picked up the hammer placed under the coffee table and hit Jin Dayuan on the right side of his head.

Jin Dayuan was still talking loudly, but the next moment he was hit by Liu Wei with a hammer. With a look of disbelief, he lost consciousness, slowly fell from the sofa and knelt on the ground, his head falling on the On the coffee table.

At this moment, Liu Wei felt that there was a devil's voice in his mind, which kept urging him to kill the ugly man in front of him, so he hit Jin Dayuan's head hard again.

Jin Dayuan was smashed to death, but the anger in Liu Wei's heart did not fade away. He looked around, the voice in his mind was still there, kill him, kill him, kill him. Just then he heard the movement in the living room. Jin Dayuan's wife came out of the bedroom and wanted to see what was going on in the living room.

But when Jin Dayuan's wife saw the situation in the living room, she only had time to scream, and then she was frightened and stood stupidly at the door of the bedroom, not daring to move.

Liu Wei took the hammer and walked towards Jin Dayuan's wife. At this time, Liu Wei had only one thought in his mind: kill him, kill him.

So without any surprise, Liu Wei hit Jin Dayuan's wife to death with a hammer. Then Liu Wei saw the two children who were still sleeping in the bedroom. He walked towards the two children with the hammer and killed them without any hesitation. Had two children.

After Liu Wei killed all four members of Jin Dayuan's family, Liu Wei suddenly felt conscious.

"I looked at Xiaofang and Xiaoxiang on the bed, who were beaten to a bloody pulp by me. I completely collapsed. I never thought that I would do such a cruel thing. I really never thought about killing them. ." Liu Wei said, with a somewhat painful expression on his face.

Luo Fei looked at Liu Wei. Liu Wei's expression didn't look like he was lying, and it didn't make much sense for Liu Wei to lie at this time. Liu Wei killed four members of Jin Dayuan's family. No matter what, his ending was doomed. .

interrogation room
"If Jin Dayuan suffered the consequences himself, then his wife and children were really unjust. They obviously did nothing, but suffered such an unreasonable disaster and lost their lives in vain. It can be said that the fire at the city gate affects the fish in the pond." Zhao Donglai sighed.

"Team Zhao, Liu Wei just said that there was a demon in his mind that kept telling him to kill him, kill him, and then he would kill Jin Dayuan's wife and children. Do you think Liu Wei might have a split personality or something like that?" Zhang Fan, the leader of the second group, asked suspiciously.

"Probably not. It was probably Liu Wei's first time to kill someone, and he was emotionally stimulated, so he reacted this way. Liu Wei's behavior was similar to that of Wang Yuan who accidentally killed his wife in the Jiangzhou City incident on May 5.13. He was mentally disturbed. The case of being stimulated and then killing his father-in-law and mother-in-law is the same." Zhao Donglai thought for a while.

While several people were discussing, Luo Fei and Sun Jun came out of the interrogation room.

"Well done, you worked hard today." Zhao Donglai patted Luo Fei on the shoulder and said, then looked at everyone, "That's it for today, Yang Mei. The DNA comparison results of the blood stains on the murder weapon in the technical room must be made as soon as possible, Luo Fei After you go to work tomorrow morning, try to write the case summary report and hand it over to me together with the interrogation record as soon as possible." Zhao Donglai ordered.

It was already ten o'clock when I got off work in the evening.Luo Fei was the last one from the third group to leave the office. When Luo Fei came out of the office, the offices of the first and second groups were already empty. Only the lights in the technical room were still on.

Thinking that Yang Mei hadn't gotten off work yet, Luo Fei walked over.

Sure enough, in the laboratory, Yang Mei was wearing a white coat and a ponytail, and was still doing DNA comparison experiments.

Luo Fei knocked on the door of the laboratory. When Yang Mei noticed the sound at the door and nodded towards him, Luo Fei walked into the office and walked next to Yang Mei.

"Will it take a long time?" Luo Fei asked softly.

"Come on, I'll just compare the last set of DNA." Yang Mei looked up at Luo Fei for a moment, then continued her work.

"Okay, let's go together when you're done," Luo Fei said.

"Okay" Yang Mei nodded.

Then Luo Fei sat nearby and watched Yang Mei do the experiment. He didn't say anything for fear of affecting Yang Mei.

It is said that boys who work hard are the most attractive to girls, but girls who work hard are also good-looking.

After about 10 minutes, Yang Mei finally finished comparing the last set of DNA.

"Is it over? What's the comparison result?" Luo Fei asked quickly.

"Two different DNAs were extracted from the murder weapon, which completely matched the DNA of the deceased Jin Dayuan and his wife." Yang Mei replied.

"In this way, with Liu Wei's confession and the hammer evidence, this case can be considered solved."

"Wait for me, I'll go change clothes first." Yang Mei said and walked into the dressing room next to her.

"Yeah" Luo Fei nodded.

After a while, Yang Mei came out, changed into a long gray coat, and let down her ponytail hair.

"I've changed, let's go," Yang Mei said.

After closing the laboratory lights and door, Luo Fei and Yang Mei walked down the stairs one after another and arrived at the playground.

"Yang Mei, have you had dinner? Let's go get something to eat!" After thinking about it, Luo Fei turned to look at Yang Mei next to him and said.

"Okay, I did eat it, but you probably haven't had dinner yet!" Yang Mei asked with a smile.

"I haven't eaten yet, but I'm starving now." Luo Fei said with a smile.

"Then I'll drive first. Just wait for me. I'll take you to a delicious restaurant. I guarantee you will like it very much. Her porridge is delicious." Yang Mei said as she walked toward the parking lot. Walk away.

"I'll go with you." Luo Fei quickly caught up.

The two drove the car to Xinjie and parked the car.

Good porridge road

"This is the place. Her porridge is delicious. Xiaoyue and I like to eat her porridge the most." Yang Mei introduced to Luo Fei.

"Is it so delicious? Then I have to try it tonight."

"It's really delicious. Trust me, you will definitely like her porridge." Yang Mei said with a smile and walked into the store skillfully.

"Yang Mei, are you working overtime tonight? Are you alone? Where is Xiaoyue?" A woman in her 50s greeted Yang Mei in the store. It seemed that Yang Mei and Wu Xiaoyue were indeed regular customers here.

"She's not here. This is Luo Fei, a new colleague from the criminal police team." Yang Mei introduced Luo Fei to the woman, and then introduced to Luo Fei: "This is the boss Aunt Tang. The porridge she stews is the best." .”

"Are you two?" The woman looked at Luo Fei, then at Yang Mei, and then asked with a smile on her face.

"No, no, don't make random guesses, Aunt Tang, hurry up and cook us porridge, and make some barbecue by the way, we are going to starve to death." Yang Mei quickly interrupted the middle-aged woman, and then urged.

"Okay, okay, I'll cook porridge for you, you two sit down first." The middle-aged woman said and walked to the kitchen.

"Do you often come here to eat?" Luo Fei asked doubtfully.

"Yes, as long as my parents are not at home and I am too lazy to cook by myself, I will eat at Aunt Tang's place." Yang Mei replied.

"It's not that delicious, right?" Luo Fei asked doubtfully.

Yang Mei looked at Luo Fei seriously and said: "This is just one reason, there is another reason. Aunt Tang's husband is actually from our criminal police team and is my master. He was involved in the 3.11 case last year in order to investigate this case. , was killed.”
