Since ancient times, the human heart is the most unpredictable.

Luke understood this sentence very early and roughly guessed Jin Xiuhui's motive for committing the crime.

When Kim Soo-hui was young, her conditions were better than those of her cousin Li Shan, and she always helped her cousin.

There is a certain amount of affection between the two.

But the world is full of changes, and so are the relationships between people.

With the help of Jin Xiuhui, Li Shanmei established a foothold in Los Angeles, found a good husband, and her life was getting better and better, and she was getting richer and richer.

On the contrary, Jin Xiuhui's life is still going on in the same place, and she even divorced her husband.

Before interrogating Jin Xiuhui, Luke also conducted some research on her situation.

Jin Xiuhui's financial situation is actually not bad. Although she and her ex-husband are divorced, she can receive alimony every month. Even if she does not go out to work, she can still guarantee her basic life.

People are afraid of comparison.

Seeing that my life was going in a blur, my cousin's life was getting more and more prosperous and she even became the owner of a supermarket. Their identities and situations also changed unknowingly.

Her cousin, who used to be inferior to her in all aspects, is now better than her in everything. It is inevitable that there will be a gap in Jin Xiuhui's heart.

It would be fine if the two people never met, but they both live in a Korean community and meet many times, so this sense of gap comes to mind every day.

Over time, psychological problems may easily occur.

To sum up in one sentence, it's not that Jin Xiuhui doesn't want her cousin to be well, she just doesn't want her cousin to live a better life than herself.

The truly difficult to detect poisoning cases are random poisoning cases, where there is no grudge or interest, and the poisoner does not know who will be poisoned.

This kind of case is the most difficult to find clues.

The red wine poisoning case is not a random poisoning case, and it stands to reason that it is not difficult to detect.

Because such purposeful poisoning cases are often accompanied by interests and grudges.

For example, if you ask the victim who he has conflicts with or conflicts of interest with, the person who can benefit from it will have a motive for committing the crime and may be a poisoning suspect.

In summary, benefit yourself at the expense of others.

The difficulty of this case is that there is no conflict or conflict of interest between Jin Xiuhui and her cousin.

To put it bluntly, she had no clear motive and could not gain any practical benefit from this poisoning case.

Even if Luke tells Li Shanmei that Kim Soo-hye poisoned Jiangnan Supermarket, the other party may not believe it.

Jin Xiuhui is a person who harms others but does not benefit herself.

It doesn't matter if I don't get any benefits. As long as you have losses and you are unhappy, I will be happy.

This kind of mentality is terrible and must be avoided.

But it's not uncommon.

It’s just that many people exist in the stage of thinking.

The person who is really suffering at this stage is you, and the other person doesn't know.

And Kim Soo-hye did it.

The result is that both people are miserable.

Once the other party's motive for committing the crime is figured out, the entire case will become clear.

Luke continued the interrogation, "Describe in detail how you committed the crime."

Jin Xiuhui wiped her nose with a tissue, "You already guessed it just now."

"You need to tell it yourself."

"Huh..." Jin Xiuhui sighed, "I really don't want to remember it anymore."

"You have to do this." The red wine poisoning case is just the appetizer. What is really important is the Weisen brand mineral water poisoning case.

Both poisoning cases occurred in Shanyuan Supermarket, and the time was close and the methods were similar. Based on Luke's experience, it is speculated that it cannot be a coincidence, and there must be some kind of connection.

It may even be the same poisoner.

So, the battle has just begun.

"Can I have a cup of coffee?"

Luke nodded.

Xiao Hei poured a cup of coffee and handed it to Jin Xiuhui.

"Thank you." Jin Xiuhui picked up the coffee cup and took a sip before saying slowly, "I bought red wine at Wiggins Supermarket in advance and put the laxative into the red wine.

During that time, I was very conflicted and always hesitant about whether to do this.

I also knew that there were certain risks, and I thought about giving up.

One day I received a notice that there would be a power outage around the supermarket on August 3. I knew that the cameras in Jiangnan Supermarket would also be out of power. This was an opportunity.

That bad thought took over again." Jin Xiuhui looked regretful and wiped her tears again.

"At around 11 o'clock that night, I put three bottles of poisonous red wine into my backpack and took it to Jiangnan Supermarket...and then I left.

I originally thought no one would know or see.

But an accident happened the next day. Jiangnan Supermarket was stolen. I was stunned at the time. I didn't expect that things would turn out like this.

I also had some regrets at the time... If I had known this would be the result, why would I have taken the risk and poisoned myself?

I was also worried that someone would see me, but after more than ten days there was no movement, so I felt relieved.

Until you find Jiangnan Supermarket...

I'm really stupid, why would I do something like this? Not only is it not good for me, but I'm also worried about it all day long.

I regret it so much, wuwu..."

With this confession, the case of red wine poisoning is almost certain.

Luke listened carefully, wrote down the key points in his notebook, and continued to ask,

"Tell me about the second poisoning case?"

Jin Xiuhui asked, "What is the second poisoning case?"

"There have been two poisoning cases in Shanyuan Supermarket. The first was the poisoning of Kafila brand red wine, and the second was the poisoning of Weisen brand mineral water.

Describe the reason and process of your second crime."

"No, I have not poisoned Shanyuan Supermarket, not even once. I have nothing to do with the Weisen mineral water poisoning case." Jin Xiuhui denied.

Luke stared at the other person's expression, "The two cases occurred at the same place, at a similar time, and with similar committing methods. If you say it has nothing to do with you, do you think the jury will believe it?"

"I really haven't done it.

I have seen the news, but it really has nothing to do with me. I have already admitted to the Kaffir red wine poisoning case. You can no longer throw dirty water on me. I really have nothing to do with the mineral water poisoning case."

"Have you ever bought Weisen brand mineral water?"

"No."

"Have you ever gone to a subway station to release poisonous mineral water?"

"Really do not have."

"Do you know who poisoned the Weisen mineral water?"

"have no idea."

Luke asked several questions in succession, but saw no sign of lying in the other person's expression.

Is it true that the other party has nothing to do with the Weisen brand mineral water poisoning case?

Could it be that my guess was wrong? The two poisoning cases just happened to happen at the same place, at similar times, and with similar techniques.

Coincidence is not impossible, but the probability is really low.

There are many coincidences, but the deep connections and patterns cannot be seen.

Luke calmed down and thought about it. Assuming that his conjecture was correct and the two poisoning cases were indeed related, assuming that Jin Xiuhui did not lie, she had nothing to do with the mineral water poisoning case.

So what is the connection point between these two cases?

Shanyuan Supermarket.

Luke suddenly thought of something and asked abruptly, "You said before that you put three bottles of poisonous red wine in Jiangnan Supermarket?"

"Yes."

"Did you leave any fingerprints?"

"No, I did it all with gloves on."

This is a problem. According to Rocky, he stole two boxes of Kaffir red wine from Jiangnan Supermarket. Osmond, the owner of Shanyuan Supermarket, also bought two boxes of Kaffir red wine, with six bottles in each box. A total of

Twelve bottles.

Among them, Shanyuan Supermarket sold six bottles of red wine, and there were still six bottles of red wine left in the warehouse. Luke had someone identify the remaining six bottles of red wine, and found that the remaining six bottles of red wine had not been poisoned, and there were no signs of damage to the packaging.
