It was found that Grandma Luo died of poisoning, and Grandma Luo's body was taken over by the police and sent to the refrigerator. At the same time, Jiang Caiyue also formally investigated the case.

Su Ji didn't interfere in the investigation, and he believed in Jiang Caiyue's ability. With Jiang Caiyue's help, he finally saw Grandma Luo's body in the morgue. Looking at the old man lying quietly on the white bed, he almost lost his voice.

At the same time, there is also fear, fear of death.

First, Vice President Ye’s fiancée, now Grandma Luo, and they all died of misfortune. This made Su Zui feel a sense of fear, inexplicable fear, as if there was always a breath of death that enveloped him.

On the other hand, Jiang Caiyue has already started investigating the case. The first thing to know is, what poison was the deceased infected?

After testing, we learned that this is a chemical agent and there are residual ingredients of sleeping pills. After taking it, people will not have any special reactions. If they cannot be discovered in time, they will die in a deep sleep within two hours and will not have symptoms such as vomiting.

So who drew this poison? When?

The biggest suspicion is Yang Anzhi's wife Zhou Mei, who lives in her house because the deceased lives. When visiting neighbors, he found that Zhou Mei was a bit rude and mean in her daily life.

"I didn't use poison! How dare I! Besides, although my relationship with my mother-in-law is not harmonious, I don't have to use poison to kill her!" After Zhou Mei was summoned to the interrogation room, she immediately made a pity with tears in her nose.

"I didn't say you were the ones." Jiang Caiyue looked at her coldly.

Zhou Mei was choked a little, her face flushed with embarrassment, but she hurriedly said, "I just said it wasn't the poison I made. How could I be so cruel?"

"I didn't say it wasn't yours." Jiang Caiyue was not angry.

"It's really not what I did." Zhou Mei shouted loudly.

Jiang Caiyue ignored her and directly interrogated: "When will the deceased rest last night?"

"Last night...it was about nine o'clock!" Zhou Mei replied with great thoughts.

"What did the deceased eat after supper?"

"After supper, my mother-in-law has bad teeth and never eats snacks or anything else."

"So did she take any medicine?"

"Medical? No, my mother-in-law is actually in good health. At most, drink some water before going to bed. By the way, my family and the boss bought her some nutritional supplements... It could not be a problem with nutritional supplements, right?" Zhou Mei was so scared that her face turned pale.

"Nutritional products?" Jiang Caiyue raised her eyebrows slightly, notifying the people who searched in the past to pay attention to this matter.

"According to the test, the chemicals did appear in a bottle of oral liquid, with a little sleeping pills." A colleague from the police station came back to report to her, holding a bag in his hand, which was a proof.

"Have you extracted the fingerprints on it?" Jiang Caiyue asked.

"It has been extracted, but only the deceased's fingerprints are obvious. The poisoner also knows this, probably because he is wearing gloves or wrapped in something." The policeman replied.

The clues were broken again.

The 100 ml glass bottle can be opened, so poisoning is naturally no problem. The main problem now is, who caused the poison? The incident happened at Yang Anzhi's house, and Jiang Caiyue immediately retried their family. In the end, the biggest suspicion was Zhou Mei.

"Zhou Mei, did you have an argument with the deceased yesterday, right?" Jiang Caiyue asked indifferently.

"...I just talked to my mother-in-law." The constant interrogation has made Zhou Mei's spirit almost collapse.

"That's why you poisoned your mother-in-law to death?" Jiang Caiyue suddenly raised her voice.

Zhou Mei trembled, but quickly denied: "No. I really don't. Yesterday, my mother-in-law and I just stumbled on each other, so how could we take the blame?"

"If it weren't for you, why were you nervous to let Su Zui see the body of the deceased?" Jiang Caiyue asked expressionlessly.

"I... I accidentally saw my mother-in-law's body turn black at noon today. I was worried that my mother-in-law wouldn't think about it and committed suicide. She thought it was because of the quarrel with her yesterday afternoon, so she didn't tell anyone, but her heart was discovered." Zhou Mei said hesitantly.

"Is that?" Jiang Caiyue said without comment. However, she said again: "So far, only you have important suspicions. According to regulations, we will detain you for 48 hours. Apart from eating and sleeping normally, the rest of the time will be constantly interrogated. Otherwise, who else will be suspected of murdering your mother-in-law besides yourself?"

After hearing this, Zhou Mei's mind was blank, and she was eager to clear her suspicion. She said, "Brother Yang Anyi! He came to ask her mother-in-law for the demolition payment the day before yesterday, but because he asked for too much, her mother-in-law didn't give it to him!"

Jiang Caiyue was shocked. Although Zhou Mei had many suspicions, she did not think that such a woman was the murderer. At most, she was a shrew who was unfilial to her mother-in-law.

But Yang Anyi is different. He is the No. 2 suspect, but his motive for committing the crime was not found before, so Jiang Caiyue did not alert the enemy.

"Tell me carefully about what happened the day before yesterday, and don't hide anything." Jiang Caiyue said to her.

After reviewing Zhou Mei, Jiang Caiyue focused on investigating Yang Anyi and found that he was interested in gambling. This time he lost hundreds of thousands of dollars, including more than 500,000 yuan in debt. Helplessly, Yang Anyi thought of the millions of dollars in demolition compensation in his mother's hands, and came over to ask for one million the day before yesterday, but was rejected.

"Yang Anyi came to the deceased's residence twice the day before yesterday."

"I guess it was the second time I came here and took the opportunity to poison me."

"But what's strange is, if it was poisoned the day before yesterday, why did he die of poisoning last night?"

"You go and ask when did you buy this nutrient solution?" Jiang Caiyue ordered the police officer under her.

"Yes, captain."

The nutrient solution was bought by the second son Yang Anzhi. Grandma Luo has been taking it for several months, but this bottle was bought at the pharmacy downstairs five days ago and opened the bottle that night. The old man was not flexible, so his grandson personally opened the bottle cap for her.

"Five days ago, the dosage was one cup per day, which is 10 ml. Until last night, it was supposed to have taken 40 ml, but now there are 70 ml in the bottle, which means that one day I forgot to take it, probably the night before, the day before yesterday, the day the murderer was poisoned."

"So, Yang Anyi's poison was drunk last night, and the deceased only drank it... collect evidence immediately and arrest Yang Anyi!" Jiang Caiyue ordered.

Although it was already late at night, the captain had an order and had to follow him. He immediately started to collect relevant evidence and arrested Yang Anyi overnight.

At first, Yang Anyi refused to plead guilty, but when Jiang Caiyue told him one by one about his motive, the crime process, and the presentation of a small bottle that had been discarded by him, the evidence was conclusive, and Yang Anyi, who had a mental breakdown, had to plead guilty and punish him.
