On April 11, 2025, forensic experts from the Medical Legal Institute (IML) in São Paulo conducted the exhumation of the body of educational counselor Tatiane Cintra dos Santos Cardozo in Franca, SP. Authorities suspect that Cardozo may have died from poisoning, prompting an investigation into the circumstances surrounding her death, which occurred when she was 42 years old. The Civil Police are analyzing the case, including her troubled relationship with her husband, William Ferreira Cardoso, who is also under investigation for possible involvement in her death.

William Ferreira Cardoso's lawyer, Letícia Antinori, was present during the exhumation and stated that her client is cooperating fully with the investigation. She emphasized their belief in his innocence and confidence in the work of the forensic team, the Civil Police, and the Public Prosecutor's Office. Antinori expressed optimism that justice will be served appropriately for all parties involved as the investigation continues.

The exhumation, which took place in the Jardim das Oliveiras Cemetery, lasted approximately twenty minutes, during which forensic experts worked on gathering evidence to determine the cause of Tatiane's death. The ongoing investigation aims to uncover the truth behind her untimely demise and whether foul play was involved, as her tragic story raises significant concerns about domestic relationships and the potential for violent outcomes in troubled marriages.
