After her mother-in-law came, she had diarrhea and vomited, and died a week later!

On March 22 this year, in the southeastern Brazilian city of Ribeirão Preto, 37-year-old Pilates teacher Larissa died in her apartment.

On the day of the incident, her husband Luis did not see his wife when he returned home. He searched several rooms in the house and finally found his wife lying on the bathroom floor, unconscious.

The husband is a surgeon. He claimed that he immediately carried his wife to the bed and gave her first aid, but she still did not wake up, so he called the emergency number again.

After the medical staff arrived, they confirmed that Larissa died on the spot and was registered as a suspicious death.

The police began to intervene in the investigation. The first autopsy did not find the specific cause of death. It was only found that her lungs and heart had lesions, and there was foam around her mouth and nose, which is usually the case for drowning people.

The police also conducted a toxicology test on Larissa, and this time they found the problem-

They found a toxic ingredient called chumbinho in Larissa's body. This ingredient is used to make pesticides, but in Brazil, this pesticide is not sold for home use.

In addition, Larissa's body contained trace amounts of lead.

Obviously, she was poisoned to death.

After investigation, the police quickly locked in the suspects, who were the deceased's husband Louis and mother-in-law Elizabeth.

When the police arrived at the scene on the day of the incident, Louis's behavior aroused their suspicion.

"From his reaction after discovering Larissa's death, we all suspected that he was involved."

"Because she had already had rigor mortis at the time, and he was cleaning the apartment, as if he wanted to destroy evidence."

As for Larissa's mother-in-law, she was the last person Larissa saw before she died.

A witness said that about 15 days before Larissa's death, he saw the mother-in-law looking for a place to sell lead, which made the police begin to suspect that she and her son had teamed up to kill Larissa.

The police found that the mother-in-law had called a friend to ask about lead.

Moreover, she called a friend who was a farmer and asked if she had that kind of pesticide on her farm. The friend said no, and the mother-in-law then asked where she could buy it, but in the end the friend neither gave her the pesticide nor recommended a seller to her.

But it seems that the mother-in-law still found a way to get these poisons and really did it.

The police found that in the week before Larissa's death, her husband and mother-in-law should have been poisoning her, and she was gradually poisoned.

Larissa told her friends a few days before her death that every time her mother-in-law came to their house, she would feel unwell, nausea, vomiting, diarrhea...

At that time, these symptoms did not attract her attention, but now think that she should have been poisoned at that time.

The police have basically confirmed that it was the mother and son who planned to poison and kill Larissa.

The suspect was found, but the motive was missing. The police soon found the reason why Larissa was killed.

She had just discovered that her husband had cheated on her and was planning to divorce him...

A relative of Larissa provided clues to the police.

In March this year, she found a wine cork with a date and a box of sex toys in her husband's car.

These discoveries made her begin to suspect that her husband, who had been married for 18 years, had cheated on her.

Relatives said that Larissa had confided in her that her husband had gone to Sao Paulo before, and it seemed that he was not alone. She wanted to video call her husband at the time, but he did not answer.

A few days later, Larissa found the apartment building where her husband's lover lived, squatted at the door, and filmed her husband entering the building.

Later, she confronted her husband with the video, but her husband denied cheating and said that Larissa was crazy.

Relatives said that a week later, Larissa began to feel unwell, and her mother-in-law had cooked soup for her and her husband had prescribed medicine for her.

It seems obvious that the husband was cheating on his wife and was discovered by his wife. He simply went all out and poisoned his wife with his mother.

In addition to Larissa's husband, the police also investigated his lover because he and his lover went to the cinema the day before the incident. The police suspected that the lover wanted to provide him with an alibi.

When the police found her with a search warrant and a seizure order, they were surprised to find that she was actually in the apartment where Larissa and her husband lived.

This Tuesday, Elizabeth and Louis were arrested on suspicion of poisoning and murder.

Although Louis's lover was not arrested, she is still under investigation, and the mobile phones of her and the suspect's mother and son were seized by the police.

Someone anonymously sent the police a photo of Louis and his lover. The police questioned him with the photo and made him admit to cheating.

He also confessed that after his wife was killed, he went to spend the night with his lover.

The truth of the case was revealed, but this was the result. I feel sorry for Larissa...
