Gloria Ramirez, also known as “the toxic lady,” died of kidney failure due to advanced cervical cancer. However, medical attendants at the hospital where she was taken began experiencing symptoms such as vomiting and passing out. Investigating this phenomenon, scientists at the Forensic Science Center discovered dimethyl sulfone (DMSO2) in Ramirez’s blood. They proposed a hypothesis involving the conversion of DMSO to DMSO2, which then turned into the powerful poison gas DMSO4, potentially causing the symptoms experienced by the medical staff. Another theory suggests that the hospital where Ramirez was treated may have been a secret lab for producing methamphetamines. However, this theory is uncertain and hasn’t been tested.
