Cheng Wei looked at himself in the surveillance video, and was sure that it was the video when he left that night, his face was blushing, and he didn't speak.

"And this, this is the shoe print you left on the iron railing behind the community, we have already compared, it is the shoe print you left." Luo Fei said and threw out two shoe prints taken in the technical room.

The expression on Cheng Wei's face was even more ugly.

"And this, this is your consumption record of online shopping in the past three months, and on January 7th, you bought a knife online, which is the same model as Lin Gang's."

"Now you can explain to us why you were there on the night of the crime, didn't you say you were with your girlfriend all the time? And why do your shoe prints appear on the iron railing behind the community? How could you buy a knife that is exactly the same as Lin Gang, and where is this knife now? Luo Fei asked coldly.

"I don't know." Cheng Wei leaned back in his chair, and Tie Qing's face slowly returned to normal.

Luo Fei stared at Cheng Wei expressionlessly, Cheng Wei's attitude was clear that he wanted to resist to the end and refuse to admit it.

"Cheng Wei, do you think you'll be fine if you don't admit it? With the evidence currently in the hands of the police, it is completely possible to prosecute you for murder, and it doesn't matter whether you admit it or not. Luo Fei said coldly.

Cheng Wei still leaned back in his chair and didn't say a word.

Luo Fei looked at Cheng Wei coldly, the evidence currently in the hands of the police is indeed enough to prosecute Cheng Wei, but there is still one thing missing, that is, the motive for the crime, why did Cheng Wei kill Cheng Zhiyou? can't find the reason why Cheng Wei killed Cheng Zhiyou, even if he can sue, there is a high probability of losing the lawsuit.

What is Cheng Wei's motive for committing the crime?

Luo Fei and the others suspected that Cheng Zhiyou abused Cheng Wei, but through investigation, this reason was untenable, and through Cheng Zhiyou's relatives, friends and neighbors, they learned that Cheng Zhiyou was kind and did not beat Cheng Wei at all.

Then why did Cheng Wei kill Cheng Zhiyou? For a son to kill a father, either he hates his father very much, or he has a perverted antisocial personality.

Judging from Cheng Wei's performance, the possibility of the latter is relatively low, which means that Cheng Wei should be the former, and he hates Cheng Zhiyou very much, so he will kill him.

So why does Cheng Wei hate Cheng Zhiyou so much?

For a son to hate his father so much, it must be something Cheng Zhiyou has done, and it is something that Cheng Wei cares about very much, and it is even so serious that Cheng Wei wants to kill his father.

What a normal person usually cares about most is nothing more than family affection and love, apart from these two, what else?

Love?

It's not quite like that, Luo Fei has seen Zhao Yi, and from the conversation, he can know that there is no problem with the relationship between Zhao Yi and Cheng Wei, it shouldn't be the bloody father who violated his son's girlfriend, and the son took revenge and killed his father, and the most important thing is that the relationship between Cheng Wei and his father has not been good since he was a child, that is to say, Cheng Wei's heart to kill Cheng Zhiyou may have been very young, and Cheng Wei should not know Zhao Yi at that time.

Affection?

Suddenly, Luo Fei remembered that when investigating the deceased's neighbor before, the neighbor had said that Cheng Wei's relationship with his father was not good since childhood, and Cheng Wei's mother died of cancer when Cheng Wei was very young.

Could it be that Cheng Wei's hatred for his father is related to his mother? This thought suddenly welled up in Luo Fei's heart.

"Cheng Wei, I know you hate your father because of your mother?" The next moment, Luo Fei said suddenly, staring at Cheng Wei, he wanted to verify this idea.

Sure enough, Cheng Wei's emotions obviously fluctuated greatly when he heard Luo Fei's words, although he tried to keep his face calm, but his slightly trembling lips had betrayed him, Luo Fei was sure that Cheng Wei's killing of Cheng Zhiyou had a great relationship with Cheng Wei's mother.

Then a bolder guess surfaced in Luo Fei's mind, Cheng Wei hated his father so much that he even wanted to kill him, did it mean that Cheng Wei's mother's death was related to his father.

"It was your father who killed your mother, that's why you hate Cheng Zhiyou so much that you even want to kill him, right?" Luo Fei stared at Cheng Wei and continued to ask.

Hearing Luo Fei's words, Cheng Wei's face turned red, the green tendons on his neck were highlighted, and he grabbed the desk in front of him with both hands.

Seeing Cheng Wei's reaction, Luo Fei knew that he had guessed correctly, it should be Cheng Zhiyou who killed his wife, and Cheng Wei happened to know or even see it, and then this incident became a pain that Cheng Wei could not erase from the bottom of his heart.

"You killed Cheng Zhiyou to avenge your mother, right?" Luo Fei continued to stimulate.

"That's right, if I kill him, he deserves to die, can you imagine a husband actually killing his own wife with his own hands in order not to let his wife drag him down?" Cheng Wei said loudly, tears slowly flowing down his cheeks.

"My mother had cancer, obviously she could go to the hospital for surgery, but he knew that surgery would cost a lot of money, and he would need to spend money on chemotherapy after surgery, so he gave up, he didn't take my mother to surgery, but bought some medicine for her to eat, and as the days passed, my mother's health became worse and worse, and she could only lie in bed and need help with eating and going to the toilet."

"His attitude towards his mother is also getting worse and worse, sometimes his mother calls him, he also pretends not to hear, there are many times when his mother wants to go to the toilet, he pretends not to hear, his mother can't help it, every time that time, his mother will feel ashamed and embarrassed, life is better than death."

"From that time on, I became disgusted with him, he was a hypocritical and shameless fellow, dressed in the clothes of a chameleon, one in front of the man, one in the back of the other, but if it was all there was to it, it would be fine, but he was not only a hypocritical and shameless fellow, he was also a beast."

"That day is Children's Day, I got the three good student certificate, after the event, I can't wait to take the certificate home, I want to let my mother know that I got the certificate, my mother will be very happy and proud of me, when I was a child, she loved me the most, but when I ran into the house, pushed open the bedroom door and ran in, when I saw the scene in front of me, my whole head was blank."

"The bastard was holding a pillow and covering his mother's mouth and nose, and I saw my mother's hand holding his arm, and my mother was struggling, but she couldn't let go, and I was a coward, and I was so scared that I just stood there and did nothing, and watched the beast kill my mother in front of me."

"I regret it, I regret that I didn't do anything at that time, if it was really possible, I really want to go back to that point in time, slap that timid self hard, and then go and stop that beast from killing his mother, but nothing ifs."

"Do you know what that beast told me after killing my mother? He first threatened me, saying that if I told the story, he would beat me to death, and then he told me that it was all for me, that if he didn't do it, sooner or later my mother would drag us both to death, and that my mother was better to live than to die, and it was better to die than to live. Cheng Wei said with tears streaming down his face.

Luo Fei frowned, he didn't expect Cheng Wei to kill Cheng Zhiyou.

"Let's wipe it." Seeing that Cheng Wei's face was full of tears, Luo Fei handed over a tissue.

Cheng Wei took the tissue and continued: "At that time, I was still young, and I was very timid, I was afraid that that bastard would kill me like my mother, so I didn't dare to tell anyone else about it, but I secretly swore in my heart that when I grew up, I would definitely avenge my mother." ”

"Now that it's been so many years since your mother left, hasn't the hatred in your heart changed at all? And how could you think of killing Cheng Zhiyou now! Luo Fei asked suspiciously, it stands to reason that so many years have passed, no matter how much you hated it at that time, how strong the hatred was, it was diluted by time, not to mention that the two were still father and son, and they had been with each other for so many years.

"I have never forgotten this matter of revenge, and I have planned everything a long time ago, I was just waiting for an opportunity, that bastard won 100,000 yuan on the day of the Spring Festival, I felt that the time had come, I started my plan, and successfully killed Cheng Zhiyou, but I didn't expect the police to find me, I really thought that my plan was seamless, I thought that when I killed Cheng Zhiyou, I would marry Xiaoyi, and then take Xiaoyi to leave this place and live in a place with the sea, But now I can't make that happen. Cheng Wei's mood slowly recovered.

"What about the murder weapon?" Luo Fei asked.

"The murder weapon was under the bed in my girlfriend's room, but this incident has nothing to do with her, she doesn't know anything." Cheng Wei said as he spoke, and the expression on his face became nervous.

It was actually at Zhao Yi's house, Luo Fei and Wang Yong had also been to Zhao Yi's house at that time, but at that time, Luo Fei didn't think that Cheng Wei would do it himself, nor did he think that there would be a murder weapon hidden in Zhao Yi's house, so he simply asked Zhao Yi and left, and he didn't check the house at all, so he missed the opportunity to find the murder weapon.

"Zhao Yi should know that you are going to murder Cheng Zhiyou!" Luo Fei asked lightly.

"I don't know, Zhao Yi doesn't know anything at all, she's so simple, I didn't tell her anything." Cheng Wei shook his head vigorously and said, at this time, he was still thinking about the other party, and it could be seen that Cheng Wei really cared about Zhao Yi.

Luo Fei looked at Cheng Wei with a somewhat complicated mood.

You say Cheng Wei is bad! He was so bad, he instigated his friends to steal money and blame his friends, and he plotted to kill his father.

But are you going to say that he is so bad? It doesn't seem to be bad to the end.

He killed his father because his father killed his mother, and he wanted to avenge his mother.

His love for his mother and his love for his girlfriend are all sincere.

It can only be said that fate plays tricks on people.

Outside the interrogation room

"What do you say is all this, the son kills Lao Tzu, Lao Tzu kills his wife? It's. Zhao Dong couldn't help complaining.

"Yes! It's really complicated, but when the murder weapon is found, the case will be settled. Yang Su sighed heavily.

At this time, Luo Fei and Sun Jun also walked out of the interrogation room.

"Team Zhao, team leader." Luo Fei said hello, but his eyes skimmed to Yang Mei behind Zhao Donglai, and said that he wanted to invite Yang Mei to watch a movie, but he saw that the interrogation room was coming.

Yang Mei saw Luo Fei looking at her, her eyes turned to the other side unnaturally, and her face was slightly red.

"Good work." Zhao Donglai patted Luo Fei on the shoulder.

"It should." Luo Fei replied.

"In this way, you and Yang Mei, Wu Xiaoyue, and Sun Jun will go to Zhao Yi's house again, and bring the murder weapon and Cheng Wei's girlfriend Zhao Yi back for interrogation, I suspect that Zhao Yi was also involved in this murder case." Zhao Donglai commanded.

"Yes" Luo Fei said firmly, Luo Fei saw Zhao Yi that day, Zhao Yi had a black gas on his head but it was very light, it was obvious that Zhao Yi should have known that Cheng Wei was going to kill Cheng Zhiyou, and he must have known that Cheng Wei hid the murder weapon in her house, but for the sake of Cheng Wei, she chose to conceal it, and it was obvious that Zhao Yi was guilty of covering up.

Leaving the interrogation room, Luo Fei drove the police car, and the four of them drove to Zhao Yi's residence.

Luo Fei originally wanted to say that if Yang Mei sat next to him, he could also talk to Yang Mei, but Sun Jun's wooden head would not come to the problem, so the girls sat together, and he sat directly in the co-pilot, letting Yang Mei and Wu Xiaoyue sit in the back row.

Not long after, the four of them arrived at Zhao Yi's residence, where Zhao Yi was painting at home.

When he saw Luo Fei and a few people coming to the door, Zhao Yi suddenly realized that something had happened to Cheng Wei, and his face became pale.

Then Luo Fei found the same knife as Lin Gang's under the bed in the bedroom.

At this time, Zhao Yi was completely sure that Cheng Wei had been caught by the police, because except for her and Cheng Wei, no one knew that the knife was hidden under the bed.

"Ms. Zhao, we suspect that you have something to do with Cheng Zhiyou's murder case, please come with us." Yang Mei said.

"Cheng Wei, how is he?" Zhao Yi asked softly, his voice very gentle.

Yang Mei said: "Cheng Wei has already explained everything."

Hearing this, Zhao Yi bit his lip lightly, and his face became even paler.

As soon as he returned to the criminal police team, Zhao Donglai asked Luo Fei to interrogate Zhao Yi.

Zhao Yi did not have any objection to her shielding Cheng Wei, she admitted that she knew that Cheng Wei was going to kill Cheng Zhiyou, and she also admitted that she knew that Cheng Wei hid the murder weapon in the room.

So far, the murder case of Cheng Zhiyou has been completely solved.

On the sixth day of the Lunar New Year, the criminal police team held a case summary meeting.

At the summary meeting, Zhao Donglai focused on praising the three groups and the technical room, this time the case can be solved, the two squadrons have a lot of credit, of course, the biggest credit is Luo Fei's three groups, which everyone knows well.

When Zhao Dong came to praise Luo Fei, he didn't forget to poke the connotation of the other squadron leaders, so that they could learn more from Luo Fei, which made the other squadron leaders have a lot of resentment towards Luo Fei.

Cheng Zhiyou's case also brought Luo Fei 400 gold coins, plus the remaining 200 gold coins before, Luo Fei has accumulated 600 gold coins at present, but if you want to exchange for the next fusion gene, you need to solve at least three more cases, the speed of this gold coin accumulation is indeed much slower than before, but Luo Fei does not have any dissatisfaction, with the evil eye, it is only a matter of time before he saves gold coins to buy fusion genes.
