Barbara Jankavski Marquez, the Brazilian influencer known as “Human Barbie” and “Boneca Desumana,” was found dead in São Paulo on November 2, 2025, aged 31. São Paulo’s Public Security Secretariat initially attributed her death to intoxication by an unspecified chemical substance. A later report by RedeTV! described a more specific finding involving cocaine, alcohol and cocaethylene, but the underlying forensic report and an official confirmation of that account were not available in the sources cited here.
What was Barbara Jankavski’s reported cause of death?
The first publicly reported forensic finding was that Jankavski died from intoxication caused by a chemical substance. SBT News and UOL reported the finding on December 2, 2025, citing São Paulo’s Public Security Secretariat (SSP-SP); UOL said the substance had not been identified publicly.

On May 6, 2026, RedeTV! reported that an examination conducted after Jankavski’s exhumation attributed her death to cocaine-and-alcohol intoxication involving cocaethylene, which the outlet said resulted in a fatal heart attack. This is a more specific account than the initial public finding, but RedeTV!’s report is secondary coverage: the underlying forensic document and an official primary-source confirmation were not available in the sources cited here. The later account should therefore be attributed to RedeTV!, rather than presented as independently confirmed.

What happened before she was found?
Jankavski, 31, was found dead at a residence in west São Paulo on November 2, 2025, according to CNN Brasil. Early coverage reported that police noted an injury near her left eye and marks on her back. A man who was with her reportedly told authorities that they had used illicit substances and that she became unresponsive after falling asleep.

Those details are reported observations and accounts, not proof of how the injuries occurred or of criminal responsibility. CNN Brasil also reported that a witness said Jankavski had slipped and fallen, causing the eye injury. The available reporting does not establish that explanation as a definitive finding.

Not in the reporting cited here. CNN Brasil reported that police requested a necropsy and toxicology examination and initially treated the death as suspicious. On December 2, UOL reported that the São Paulo Public Prosecutor’s Office said an intentional crime could not be ruled out and referred the matter to the jury court.
Rank #2
That referral is a procedural development, not a finding that a crime occurred and not proof that anyone was charged or convicted. The latest official investigative or legal disposition was not established by the cited sources, so it is not possible to say from them whether the case has been closed.

What remains uncertain?
- The initial public forensic finding identified intoxication by a chemical substance but did not publicly name it in UOL’s account of the SSP-SP statement.
- RedeTV!’s later report names cocaine, alcohol and cocaethylene, but its underlying forensic document and an official confirmation were not available in the cited sources.
- The circumstances behind the reported injuries and the final investigative or legal outcome are not established by the cited reporting.
