It was found out that Grandma Luo died of poisoning, and Grandma Luo's body was also taken over by the police and sent to the cold room.

Investigation Su did not interfere, 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 fear, the fear of death.

First is Vice President Ye's fiancée, and now Grandma Luo, and they all died unexpectedly, which made Su Zhi have a kind of fear in his heart, an inexplicable fear, as if there was always a breath of death enveloping him.

On the other hand, Jiang Caiyue has already started an investigation into the case, and the first thing to know is what kind of poison the deceased had?

After laboratory tests, it was learned that this is a chemical agent, and there are also residual ingredients of sleeping pills, and after taking it, people will not have a special reaction, and if they can't find it in time, they will die in a deep sleep within two hours, and there will be no symptoms such as vomiting.

So who gave this poison? When was it ordered?

The biggest suspect is Yang Anzhi's wife Zhou Mei, because the deceased lived in her house, and a visit to the neighbors found that Zhou Mei was a little rude and mean to the deceased on weekdays.

"I didn't give the poison! How dare I! What's more, although my relationship with my mother-in-law is not harmonious, I will not poison her to death! After Zhou Mei was summoned to the interrogation room, she immediately avenged her grievances with a handful of snot and tears.

"I didn't say you ordered it." Jiang Caiyue looked at her coldly.

Zhou Mei was choked a little, and her face was flushed with embarrassment, but she was busy saying: "I just said that it wasn't me who poisoned me, how could I be so cruel?" ”

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

"I really didn't do it." Zhou Mei shouted.

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

"Last night...... It's about nine o'clock! Zhou Mei replied thoughtfully.

"What did the deceased eat after dinner?"

"After dinner? My mother-in-law has bad teeth and has never eaten snacks or anything like that. ”

"Did she take any medicine?"

"Medicine? No, my mother-in-law is actually in good health, so drink more water before going to bed. That's right. My family and the eldest bought her some nutritional supplements...... It can't be a problem with nutrition, right? Zhou Mei's face turned pale with fright.

"Nutrition?" Jiang Caiyue raised her eyebrows slightly, noncommittal, but she informed the people who searched in the past to pay attention to this matter.

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

"Did you extract the fingerprints on it?" Jiang Caiyue asked.

"It has been extracted, but only the fingerprints of the deceased are the fingerprints, and apparently the poisoner also knew this, probably wearing gloves. Or wrapped in something. The officer replied.

The clue is broken again.

100 ml glass bottle, the lid can be opened, poisoning is naturally not a problem, now the main question is, who is poisoning? The incident happened at Yang Anzhi's house, Jiang Caiyue immediately retried their family, and the biggest suspect in the end was Zhou Mei.

"Zhou Mei, you had a quarrel with the deceased yesterday, right?" Jiang Caiyue asked indifferently.

“…… I had a couple of words with my mother-in-law. "The constant interrogation has made Zhou Mei's spirit close to collapse.

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

Zhou Mei shuddered for a moment, but quickly denied it: "No." I really didn't, yesterday my mother-in-law and I just stumbled a few words, how could I be poisoned. ”

"If it weren't for you, why would you be nervous about letting Su go to see the body of the deceased?" Jiang Caiyue asked expressionlessly.

"I ...... I accidentally saw my mother-in-law's body blackened at noon today. I was worried that my mother-in-law couldn't think of what she drank and committed suicide, thinking that it was because of the quarrel with her yesterday afternoon, so she didn't tell anyone, but her heart was discovered. Zhou Mei said in a hurry.

"Really?" Jiang Caiyue was noncommittal. But he said: "So far, only you have important suspicions, according to the regulations." You will be detained for 48 hours, except for normal meals and sleep, and the rest of the time will be constant interrogation. Why don't you tell me, besides yourself, who else is suspected of murdering your mother-in-law? ”

Zhou Mei's brain was already blank after hearing this, and she was also eager to clear her suspicions, so she opened her mouth and said, "Big brother Yang Anyi!" He came to his mother-in-law the day before yesterday to ask for the demolition money, but because he asked for too much money, his mother-in-law didn't give it to him! ”

Jiang Caiyue's spirit was shocked, although Zhou Mei had many suspicions, she didn't think such a woman was a murderer, at most she was a shrew who did not respect 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 startle the snake.

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

After interrogating Zhou Mei, Jiang Caiyue focused on investigating Yang Anyi, and found that he was actually a good gambler, and he lost hundreds of thousands of dollars this time, including more than 500,000 arrears. Helpless, Yang Anyi thought of the millions of demolition compensation in her mother's hand, and came to ask for one million the day before yesterday, but was refused.

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

"I guess I took the opportunity to poison it when I came for the second time."

"But the strange thing is that if it was poisoned the day before yesterday, why did you die of poisoning last night?"

"Go and ask when you bought this nutrient solution." Jiang Caiyue instructed the police officers under him.

"Yes, Captain."

The nutrient solution was bought by the second eldest Yang Anzhi, and Grandma Luo has been taking it for the past few months, but this bottle was bought at the pharmacy downstairs five days ago, and she opened the bottle and took it that night. The old man's hands are not flexible, and the bottle cap is opened by her grandson himself.

"Five days ago, the daily dosage was one cup, that is, 10 milliliters, and as of last night, it was supposed to have taken 40 milliliters, but now there are still 70 milliliters in the bottle, which means that one day during this period I forgot to take it, probably the night before yesterday, the day the murderer poisoned it."

"Therefore, Yang Anyi's poison the day before yesterday, the deceased only drank it last night...... Collect evidence now and arrest Yang Anyi! Jiang Caiyue ordered.

Although it was already late at night, the captain had an order and had to immediately start collecting relevant evidence and arrest Yang Anyi overnight.

At first, Yang Anyi refused to admit guilt, but when Jiang Caiyue told his motive for committing the crime, the process of committing the crime, and showing a small bottle that had been discarded by him, the evidence was conclusive, and Yang Anyi, who had a mental breakdown, could only plead guilty and surrender to the law
