A Brazilian doctor and his mother have been arrested on suspicion of poisoning his wife. The case, initially treated as a suspicious death in Ribeirão Preto, took a turn after toxicology reports revealed the presence of a substance commonly used as rat poison in the victim’s body.
Extramarital Affair and Alleged Evidence Tampering
The alleged crime occurred in March. According to investigator Fernando Bravo, the behavior of Dr. Luiz Antonio Garnica raised suspicions upon arrival at the apartment after the death of his 37-year-old wife, Larissa Rodrigues, a fitness instructor.
Bravo stated that Garnica appeared to be attempting to clean the apartment, “as if he wanted to erase evidence.” He also noted that Rodrigues’ body “was already in rigor mortis.”

Investigators learned that Rodrigues had discovered her husband’s extramarital affair and had confided in close friends about it.
Garnica’s alleged lover is also under investigation, and her phone, along with those of Garnica and his mother, have been seized by police. Bravo said Garnica was reportedly seen at a movie theater with his lover the day before Rodrigues’ death, perhaps establishing an alibi.
According to the police report, garnica claimed he found his wife collapsed and unconscious when he returned home on March 22. He stated he attempted emergency procedures before calling for an ambulance.
Mother-in-Law’s Role and Suspected Progressive poisoning
Garnica’s mother, Elizabete Arbaça, was reportedly the last person to see Rodrigues alive.
Testimony indicates that Arbaça inquired about purchasing rat poison days before Rodrigues’ death. “She called a friend asking about the poison about 15 days before,” Bravo said.

“She even called a farmer to find out if he had this substance on his farm. When his friend told him no,he asked him to recommend where to buy it,but they did not give him or recommend anything,” he said. “This gave us certainty that she, along with her son, killed Larissa,” Bravo stated.
Police suspect the poisoning was progressive, as Rodrigues had reported feeling unwell each time she saw her mother-in-law. “It presented some symptoms that, today we realize, they already indicated poisoning,” the detective said.
