California's Unsolved Mysteries The Toxic Lady of Riverside

On February 9, 1994, Gloria Ramirez, a 31-year-old woman with terminal cervical cancer, was admitted to Riverside General Hospital in Riverside, California.

Shortly after her arrival, medical staff began to fall ill due to toxic fumes emanating from her body. Despite extensive investigations, the cause of the toxicity remains a mystery.

Ramirez was in Stage 4 cervical cancer and experiencing renal failure and cardiac arrhythmia. Upon her admission, standard emergency treatments were administered. However, when a blood sample was taken, an ammonia-like smell was detected, and mysterious particles were observed in her blood.

Following this, staff members, including nurses and doctors, started to faint and feel sick, leading to the evacuation of the emergency room.

Ramirez died 45 minutes after arriving at the hospital.

The case, known as “The Toxic Lady,” prompted a large forensic investigation. Autopsy and toxicology tests on Ramirez’s body revealed no abnormalities. The Riverside coroner, under public pressure to identify the toxic substance, collaborated with various departments but could not find a conclusive answer.

A theory emerged from Lawrence Livermore National Laboratories, suggesting that Ramirez might have been using dimethyl sulfoxide (DMSO), a substance which, under certain conditions, could convert into a toxic gas. However, this theory was contested by other scientists and Ramirez’s family.

An alternative theory, presented by the New Times LA, suggested that methylamine, a chemical used in both hospital cleaning and illegal drug manufacturing, might have been accidentally administered to Ramirez, causing the toxic fumes.

This theory aligned with the known effects of methylamine exposure and the hospital’s location in a region known for methamphetamine production.

The case remains unresolved with scientific explanations contested, and the possibility of a simpler, more direct cause, like methylamine exposure.

The unusual circumstances of Ramirez’s death and the subsequent illness of the medical staff continue to be a subject of speculation and debate.
