Everyone thought that Lu Yuanyuan's case had come to light, and they thought that they could spend a quiet and pleasant weekend.

The appearance of forensic doctor Li Nuofan shattered the dream in everyone's hearts.

"Nuo Fan, what's wrong with you?"

Captain Chu saw that Li Nuofan's face was covered with dark clouds, after so many years of colleagues, she must have something.

"I'm sorry to everyone here, I think I need to apologize, the autopsy report I gave in Lu Yuanyuan's case was wrong."

"You've discovered something new."

Captain Chu has always had doubts about the cause of Lu Yuanyuan's death.

"Yes, Lu Yuanyuan did not die from a fever that caused the failure of her body's organs, she was murdered."

Li Nuofan examined Lu Yuanyuan's body again and found two chemicals, dimethyl and dichlorodisyridine, which are the main components of a poison, in the infected area of the wound on the deceased's right thumb.

"What poison?"

Everyone stared at Li Nuofan in unison.

"Paraquat."

"Death water paraquat?"

Xiao Bing was surprised.

"I cut open the wound on the thumb of the deceased Lu Yuanyuan's right foot, and found that dimethyl and dichlorodisyridine can also be tested deep in the wound, but very rarely."

"What does that mean?"

"I can deduce that the wound on the thumb of the deceased Lu Yuanyuan touched paraquat at least twice, and the dose was very small, but it was all wound stained."

Finally, Li Nuofan gave Lu Yuanyuan's autopsy report, and the cause of death was high fever caused by paraquat contamination of the wound and death caused by body organ failure due to asthma.

The cause of death was murder, and the case was determined to be murder.

At the same time as convicting the deceased's case of murder, everyone guessed Captain Chu's order.

"I'm working overtime this weekend, and I'm ready to work."

Next, we need to analyze the facts of the case and see where this case should break through.

Wu Mo thought of what Lu Yuanyuan's mother had said.

"Team Chu, I think it's necessary to talk about this incident that Lu's mother told me."

"You said, as long as it is about the case, you have to talk about it, and you have to talk about big and small things."

The principle of the Youcheng Criminal Investigation Brigade is not to miss any clues, even if it is a drop in the ocean.

Wu Mo added Lu's mother's name to the whiteboard.

"Lu's mother told me about something five years ago, and now this case has been convicted of murder, and I think it's a little suspicious, so I'll tell you about it. Lu Yuanyuan was pregnant five years ago, and the child was induced in his hometown when he was five months old. The boss's daughter-in-law beat Lu Yuanyuan after she found out, and the child couldn't save the labor induction operation. ”

"It's a boss, and the child's father is not Wang Yuewei."

Captain Chu was very sure that at a certain moment, he was a little suspicious of Wang Yuewei, could it be that he had been dodging and dodging his intuition?

"It's not Wang Yuewei, Lu Yuanyuan and Wang Yuewei met three years ago. Wang Yuewei didn't know about Lu Yuanyuan's induction of labor. ”

This matter is very important, and perhaps it is the breakthrough of the case.

"Find out this so-called big boss, and his daughter-in-law will also find out."

Xiao Bing took Lu Yuanyuan's mobile phone from the Physical Evidence Identification Center and wanted to inquire about the news from Lu Yuanyuan's friend.

"Wu Mo informed Wang Yuewei to come to the team and make a record for him."

"Understand Team Chu."

Lu Yuanyuan had bought medicine, and her wound was contaminated with paraquat, so she should have found this pharmacy as soon as possible.

Xiao Bing went to check the pharmacy with the master, and Liu Muyang checked the surveillance video of the Guili community that was copied back again.

Captain Chu wanted to see Wang Yuewei and didn't go out.

Soon Wang Yuewei rushed to the criminal investigation team, probably because of the sadness and loss, Wang Yuewei looked much more decadent than in the morning.

"Wang Yuewei, we have something to ask you, I hope you will cooperate well."

Wang Yuewei was a little confused by what Wu Mo said, he thought that his family came to sign, and he thought that the case was over.

The transcript made for Wang Yuewei in the interrogation room can record everything in this room.

Captain Chu asked, and Wu Mo was in charge of recording.

"Wang Yuewei, how is your relationship with your daughter-in-law Lu Yuanyuan?"

"Captain, what do you mean by this, I love Yuanyuan very much, and our relationship has always been very good."

Wang Yuewei's mood was a little excited, and Captain Chu could see that Wang Yuewei really loved Lu Yuanyuan.

"You met three years ago, what did Lu Yuanyuan do three years ago?"

"When I met Yuanyuan, she worked in the hotel, the front desk of the hotel."

"Which hotel? Is it still in operation? ”

At this time, Wang Yuewei's eyes were full of tears.

"Shilin House, the hotel I stayed in today is there, and I met Yuanyuan in Shilin House."

Captain Chu was also compassionate, and he thought about quickly diverting the topic.

"Did Lu Yuanyuan have an enemy before his death?"

This question really diverted the topic, and Wang Yuewei immediately controlled his sad emotions.

"Captain, was my daughter-in-law killed?"

Wang Yuewei was very smart, he knew what Captain Chu's words meant.

"That's right, the forensic doctor of our criminal investigation brigade has confirmed that your daughter-in-law, Lu Yuanyuan, was murdered and died."

At this moment, Captain Chu stared at Wang Yuewei tightly, he wanted to see something from his expression, but Captain Chu was disappointed.

"Yuan Yuan is very good, she didn't offend anyone, she is very kind, who will harm her, she ......"

"When was the last time you contacted Lu Yuanyuan?"

This is the job of a criminal investigator, anyone can be suspicious, only evidence can get rid of everything.

Wang Yuewei thought for a while: "Yuanyuan called me at about nine o'clock last night, and this was our last call. ”

"Did you hear anything unusual on the phone?"

Wang Yuewei shook his head.

"I was at a drinking party, I chatted with Yuanyuan for a few minutes, she was not feeling well and wanted to go to bed early, I also told her to drink cold medicine, when I called the day before, she told me that she had a cold and fever, I didn't feel anything abnormal."

After pausing for a while, Wang Yuewei thought, "Yuanyuan said that she would surprise me when I came back from a business trip, and she said that she had good news to tell me." ”

Once again, this so-called good news was withheld.

It is also a virtue to be secretive at a certain moment.
