I'm just a trainee police officer. I don't really want to solve the case.

When the team members heard Su Xiaoxiao say that the murderer had been found, they all gathered around.

"Tell me what you think." Qi Lei looked at her encouragingly. This little policewoman had left a deep impression on him in the police academy. Maybe she could really open up his mind.

"Look here." Su Xiaoxiao pointed to a photo on the whiteboard. The photo was a close-up of Liu Lijuan's neck. "There are two marks here, one is a strangulation mark, and the other is a pinching mark. The pinching mark covers the strangulation mark. We all thought that these two marks were left by the same person, but what if not?"

"You mean there is more than one murderer?" Qi Lei's eyes lit up and he immediately understood the key.

"Yes, there were two murderers who took turns to kill Liu Lijuan. The first one strangled Liu Lijuan with a rope, but he thought she was dead, but she wasn't. The second one was the one who finally killed her.

We have been comparing the second person's fingerprints to the first person's, so the fingerprints will never match."

"So, what you mean is that it was one person who dumped the body, and it was another person who actually killed her. But this is not right. Let's not talk about who dumped the body, but we have also compared Zhao Quan, and it's not him." Guo Zhongliang was very confused.

"Yes, it's definitely not Zhao Quan. But don't forget, the little beggar said he saw a man dragging a woman. He said the man looked familiar, like one of the two. We all thought it was the missing Zhao Quan, but it was actually Li Dazhu."

"Li Dazhu?"

"Yes, Li Dazhu misled us and made us think it was Zhao Quan, but in fact it was he who strangled Liu Lijuan to death.

He also saw the van dumping the body, so after Zhao Quan fell asleep, he got up, put on his raincoat, and went to see what the van had dumped. I think Liu Lijuan must have had more than one purse on her. I remember she was wearing a necklace. Maybe he just wanted the necklace, but Liu Lijuan woke up, and he panicked and strangled her to death. "

Su Xiaoxiao pointed at a slight scratch on Liu Lijuan's neck.

"You can see there is a very thin scratch here, which may be left when he pulled the necklace off. The first person who wanted to kill Liu Lijuan was not after her property, so he did not touch Liu Lijuan's things. Her bag and necklace were still on her body."

The prompt given by the system was not wrong, she just misunderstood it before.

"Okay, even if that's the case, then tell me who the first person is?" another team member spoke up. Everyone was skeptical about what she said.

"In fact, we have all met this person. We just took his statement here this afternoon."

"Are you talking about Liu Chengdong?" Qi Lei thought for a moment. There were three people who had taken statements here in the afternoon, Gu Dacheng, the taxi driver, and Liu Chengdong.

The taxi driver and Gu Dacheng did not have time to commit the crime, but Liu Chengdong had no witnesses. He said that it was raining that night and business was slow, so he closed early. He had already gone to bed at that time because he lived alone above the restaurant.

If we exclude the issue of fingerprint mismatch, he does look like the most suspicious. The last place Liu Lijuan was seen was his restaurant, and the restaurant is very close to the stolen van. He may also have known that the owner was not at home that night and stole his car to dispose of the body.

But there is no evidence for this, and he couldn't figure out why Liu Chengdong did this.

"Liu Chengdong had no grudge against Liu Lijuan, so why did he kill her?" Guo Zhongliang asked the same question.

It is not necessarily true that there is no grudge or hatred. For some grudges, even the victims may not even know how they were formed.

"When I saw the wounds on Liu Lijuan's private parts yesterday, I thought the murderer must have known Liu Lijuan and hated her, so he would vent his anger in this way.

Among the people we investigated, apart from Gu Dacheng, only Liu Chengdong and Liu Lijuan knew each other. But what kind of grudge would make him treat a woman in this way?

I asked Zhang Qiang about it.

On the surface, Liu Chengdong and Liu Lijuan had no grudges against each other, and they were even victims of the same case.

Five years ago, Liu Lijuan was having dinner at Liu Chengdong's restaurant when she was molested by a drunk man. Liu Chengdong tried to stop the molestation but was also beaten by the man. It was Zhang Qiang who passed by and subdued the assailant and saved them. The man who committed the molestation was named Zhou Ye and was later sentenced to five years in prison.

In this incident, although Liu Lijuan and Liu Chengdong were both victims, the results were very different.

Liu Lijuan was only slapped and suffered some minor skin injuries. Afterwards, she became Zhang Qiang's girlfriend. It can be said that she not only did not suffer any loss, but also gained love.

Liu Chengdong was beaten to the point of foaming at the mouth. His other injuries were minor, but Zhou Ye stomped on his vital parts, turning him into a eunuch from then on.

His wife couldn't accept it and wanted to divorce him. She also aborted the baby in her belly, which might be the only child in his life.

He refused to divorce, but I heard that his wife ran away with someone else later.

This incident was a devastating blow to him.

He has not been interested in running the restaurant in recent years, and business has been bad, so he can only make a living."

"But this is not Liu Lijuan's fault, right? If he wants to hate someone, he should hate Zhou Ye." said a team member.

"Yes, rationally it is indeed not Liu Lijuan's fault, but people are sometimes irrational.

The guy named Zhou Ye was released from prison half a month ago. I checked and found that Liu Chengdong's restaurant was smashed a few days ago. It should be Zhou Ye who hired someone to do it. He reported the case but later withdrew the report. He might have been threatened by someone.

He didn’t know whether Zhou Ye would seek settlement with Liu Lijuan, but his restaurant couldn’t escape.

In this case, if he saw Liu Lijuan and saw that she was still alive and well, do you think he would think that all this was caused by her? !

After all, it all started when Zhou Ye flirted with Liu Lijuan."

Qi Lei took a deep breath. When a person is in a bad situation, he will transfer his resentment to others, even if he knows that the person is innocent.

The psychology of this kind of person cannot be judged by that of a normal person.

"Another key point is that there was a little white powder mixed in the wound on Liu Lijuan's lower body. Forensic doctor Zhang said it was flour. There was something in the restaurant that was stained with flour and matched the shape of the wound."

"Rolling pin." Qi Lei blurted out. Liu Chengdong was inhumane and could not violate Liu Lijuan, so he used this method to vent his resentment.

He already believed Su Xiaoxiao's words to about 80%, so without any hesitation, he threw away the cigarette butt in his hand and ordered his soldiers to split into two groups to carry out the arrest.

He followed him to the restaurant to capture Liu Chengdong, and was led by Guo Zhongliang to capture Li Dazhui.

The arrest went very smoothly. When Qi Lei arrived at Tuguo Street, Liu Chengdong was being pinned to the ground and beaten by several people.

When those people saw that it was the police who kicked the door in, they were stunned and were handcuffed before they could figure out the situation.

When Liu Chengdong saw the police's posture, he knew that his crime was exposed, and he collapsed to the ground without trying to resist.

Guo Zhongliang's team was also lucky. Li Dazhui was packing his luggage and preparing to leave when he bumped into him and was directly asked to get into the police car.

In the interrogation room, Liu Chengdong admitted that he had killed Liu Lijuan. When Qi Lei asked him why he killed Liu Lijuan, the expression on his face suddenly became ferocious.

"Why did I kill her? Is that even a question?!

That bitch, she deserves to die! If it weren't for her, how could I become what I am now? !

Why did she want to provoke Zhou Ye? Why couldn’t she just go along with him? It wouldn’t kill her if she touched him!

If she hadn't come that day, nothing would have happened. Why did she come to harm me? Why didn't she harm others? "

Liu Chengdong roared at the top of his lungs.

"Look at the way she's dressed, she's not a decent woman. Zhang Qiang treated her like a treasure, but she still dumped him.

She is just like my wife, a fickle and slutty woman.

They all deserve to die, all deserve to die!!”

He kept repeating "damn it" in his mouth, as if he had gone crazy.

Qi Lei was shocked when he heard this, and hurriedly ordered Guo Zhongliang, "Go check the whereabouts of Liu Chengdong's wife immediately."

"Okay, I'll go right away." Guo Zhongliang was stunned for a moment, then he understood.

"You don't need to check. I killed her. I killed her and her wild man. I dumped their bodies in the creek next to Nanshan Mountain."

Liu Chengdong suddenly calmed down and a sarcastic smile appeared on his face. They would all die anyway, so it didn't matter if one more or one less.

Everyone in the interrogation room was stunned. One life became three. This guy is really crazy.

The case was solved successfully and Li Dazhui pleaded guilty, but no one expected such a result.

[Meow, congratulations to the host for completing the task, rewards are randomly dropping...]

Hearing the system prompt, Su Xiaoxiao breathed a sigh of relief, finally completing the task before the deadline.

Last time I got the top lock-picking skill. What reward will I get this time? I’m really excited just thinking about it.
