Overview

• Officials said the August 11 deaths in a São José motel bathtub resulted from exogenous poisoning favoring heatstroke, leading to organ failure.
• Investigators reported the tub’s water temperature exceeded about 50°C (122°F) and a room heater was set high, creating hazardous conditions.
• Toxicology tests found very high blood alcohol levels and traces of cocaine, which forensic experts said can blunt awareness and defensive reactions to extreme heat.
• Civil Police said they found no evidence of carbon monoxide poisoning, drowning, electric shock, or third‑party involvement after examining the room, car, and security footage.
• Relatives of Ana Carolina Silva dispute that she used drugs and allege possible forced ingestion, calling for a rigorous and transparent investigation.
