Chapter 48 Reversal of Verdict: Shen Yuanyuan Case

"Fang Rui, I think you have some talent for crime! But," Mu Mian retorted, "we didn't detect the ingredients of that kind of aphrodisiac in Lin Qianjie's body. This possibility is ruled out."

Fang Rui felt that it was unlikely that Chen Dongdong had poisoned Lin Qianjie. He had a close relationship with Lin Qianjie. If he really wanted to poison him, he could have chosen a time when he was not around and let Lin Qianjie die from the poison.

And Wang Xiaoya was his girlfriend. If he only wanted to poison Lin Qianjie, he could have stopped Wang Xiaoya from drinking the poisoned wine.

In this case, Xu Qin was very suspicious.

Fang Rui focused on investigating Xu Qin.

"Boss, Xu Qin and Shen Yuanyuan are from the same high school," Xiao Zhang said, holding a photo. "This is their graduation photo. They were in the same class for three years in high school. From the photo, it seems that they have a good relationship."

There are three girls in the photo, and they are all smiling happily.

The third girl in the photo is Shen Meilin. She did not go to college after graduating from high school, but she also works in Jiangzhou City, so she has contact with Shen Yuanyuan. When Shen Yuanyuan was in court before, she was by her side.

Shen Meilin works as a waitress in a hotel.

"Oh, I should have stayed with Yuanyuan at that time," Shen Meilin sighed, "After the lawsuit failed, Yuanyuan suffered from severe depression. At that time, I accompanied Yuanyuan for many days together with Prosecutor Nie who was in charge of Yuanyuan's case. Later, Yuanyuan cheered up and found a job. We thought she had recovered from her illness and started to live a new life, but she suddenly jumped off the building and committed suicide!"

Fang Rui took out the photo and asked, "What about Xu Qin? How did she react after Shen Yuanyuan committed suicide?"

"How can such a gold-digger react? It's her fault that Yuanyuan is like this. If she hadn't introduced Yuanyuan to Lin Qianjie, would Yuanyuan have suffered such a tragic fate? She is so vicious! At that time, she even dragged me to meet Lin Qianjie. Fortunately, that scumbag didn't like me. Xu Qin, that bitch, I scold her every time I see her!"

Shen Meilin became more and more excited. Shen Yuanyuan and she are from the same village. The two grew up together and have a very good relationship.

"How is the relationship between Xu Qin and Shen Yuanyuan?" Fang Rui asked.

"Very good! Originally, Yuanyuan and I were close friends, but after Xu Qin came along, I became a marginal figure in this friendship. That's why I was so angry. Yuanyuan trusted her so much, but she knew clearly about Lin Qianjie's crimes, but she refused to testify in court, causing Yuanyuan to lose the case."

Shen Meilin sighed, "Yuanyuan hated her before she died, so she specifically called her downstairs and fell to death in front of her. If she still had a conscience, she probably wouldn't be able to sleep for the rest of her life."

"Okay, thank you for your cooperation."

On the way back, Xiao Zhang analyzed: "Boss, do you think the murderer is Xu Qin? If she and Shen Yuanyuan are really good friends, then she must resent Lin Qianjie. On the day of the incident, Lin Qianjie won the lawsuit again. Maybe it stimulated Xu Qin, and she couldn't help but poisoned Lin Qianjie."

Fang Rui felt that Xiao Zhang's analysis made sense. When taking notes for Xu Qin before, she mentioned Wang Xiaoya with disdain on her face, and said that Wang Xiaoya would feel guilty about Lu Tian's affairs. Could this be her self-projection?

"Let's go talk to Xu Qin again!" Fang Rui said.

Xu Qin studied fine arts and now teaches children to paint in a counseling institution. When Fang Rui found her, she was instructing a child to color.

Xu Qin took Fang Rui to her office.

"Officer Fang, Officer Zhang, please have some tea!" Xu Qin poured two cups of tea for Fang Rui and the others, then sat down on the sofa.

Fang Rui didn't drink the tea. He noticed a sketchbook on the table, so he picked it up and flipped through it.

The painting was in color, but the lines were blurry. It didn't look like a painting, but more like colors smeared randomly on paper. Although Fang Rui didn't understand psychology, it could be seen from these paintings that the mental state of the people who painted these paintings was not very good.

He took out his phone to take a picture, intending to let Mu Mian see it later. Mu Mian has been receiving painting therapy for a long time, so he should know a lot about this.

"Ms. Xu, did you draw these paintings?" Fang Rui asked casually, "They are very special!"

"Yes," Xu Qin nervously snatched the album and stuffed it into the drawer, "I've been obsessed with modernist painting recently. I just painted them for fun. They are very abstract, right? Modernism is in this style."

Seeing that Fang Rui didn't drink the tea, Xiao Zhang didn't dare to drink the tea either. He was afraid that Xu Qin would poison the tea and kill them both.

Xiao Zhang asked, "Ms. Xu, do you still remember Shen Yuanyuan?"

Hearing this name, Xu Qin froze. She asked cautiously, "What does this case have to do with Yuanyuan? Yuanyuan's parents are farmers. They couldn't have poisoned Lin Qianjie to death. Don't harass her parents. It's already very pitiful that they have to send their son to his grave."

Fang Rui asked, "Do you feel guilty about Shen Yuanyuan's death?"

"Why should I feel guilty? I didn't rape Yuanyuan, nor did I push her down the stairs. Why don't you blame Lin Qianjie? Why do you blame me? I can't help it. I don't want this to happen..." Xu Qin was a little out of control, tears kept pouring out of her eyes, "Yuanyuan's death was not caused by me!"

Xiao Zhang asked, "Then don't you hate Lin Qianjie? He killed your best friend, and you still followed him. Aren't you afraid that Shen Yuanyuan will die with regrets?"

Xu Qin's mind once again appeared Shen Yuanyuan's bloody body and her wide-open eyes. These scenes became her lingering nightmares.

Her spirit was a little broken, and she tried to defend herself: "This society is a place where the strong prey on the weak. Even the law can't do anything to him, so what can I do? If I help Yuanyuan, I might be the one to die!"

Xu Qin finally realized Fang Rui's purpose, "Officer, I didn't poison Lin Qianjie, it wasn't me!"

"If it wasn't you, then it could only be Chen Dongdong." Fang Rui said, "Did he do anything suspicious on the night of the incident?"

"Wang Xiaoya likes Lin Qianjie, and she has always been flirting with him. No man can tolerate being cuckolded."

Xu Qin continued, "He also knows a lot of people in the underground market, and can often buy contraband. It is also easy for him to buy poison. I think he is the murderer!"

Xu Qin recalled, "Before going to the pier that day, I saw Wang Xiaoya and Chen Dongdong arguing, and the argument was a bit fierce. Could it be that Chen Dongdong wanted to poison Wang Xiaoya, and maybe Lin Qianjie accidentally drank the glass of wine, so he poisoned Lin Qianjie to death? Officer Fang, you should investigate Chen Dongdong carefully, he might be the murderer!"

It was dark when Xu Qin left the counseling center where she worked.

"Boss, judging from the motive of the crime, both Chen Dongdong and Xu Qin had the motive to commit the crime; and they also had the opportunity to commit the crime, but it is difficult to prove who is the murderer. If the poison was first put into the cup, it would be difficult to leave evidence."

The clue of the source of the poison could not be carried out. There is no clear sales channel for rat poison, and it is difficult to trace the source of the poison.

When Fang Rui returned to the bureau, he found that Mu Mian was still working overtime. She was lying on the table with papers on it, and seemed to be doing calculations.

Fang Rui put his phone in front of Mu Mian, on which were paintings by Xu Qin: "Mu Mian, these paintings are very strange. Can they reflect the psychological problems of the painter? For example, antisocial personality or something like that?"

Mu Mian looked at the colors that were smeared together. She thought for a while and said: "According to the principle of the painting test, the painter is likely to have depression. She needs psychological treatment."

"These paintings were painted by Xu Qin. I thought these paintings represented that she was very aggressive. Now it seems that she is not the murderer."

"But the murderers of many poisoning cases are not aggressive. The murderers of such cases are usually women. They can't retaliate through violence, so they can only use poisoning." Mu Mian said while continuing to calculate on the paper.

"What are you calculating?"

"Liquid concentration." Mu Mian replied, "I've finished the calculation."

Fang Rui took a look. The paper was full of formulas and he didn't quite understand them.

"What's the point of this?"

Mu Mian drew two glasses of wine on a piece of paper, one of which was marked as poisoned wine, and the other three were blank. Mu Mian pointed to the poisoned wine and said, "I analyzed the ingredients of the west glass of wine. This glass of poisoned wine has the same ingredients as the other three glasses, except for the addition of rat poison. But their alcohol concentrations are very different."

"This glass of poisoned wine has more rat poison, which will definitely affect the alcohol concentration. Do you suspect that the murderer put a lot of poison in it?"

Mu Mian sighed. She felt that Fang Rui was a little stupid now.

"Mu Mian, tell me the correct answer first." Fang Rui couldn't help but ruffle Mu Mian's hair, "Don't complain about me being stupid in your heart!"

Mu Mian explained, "This shows that this glass of poisoned wine has been diluted."
