A Medical Mystery Unfolds

In late December 1996, a series of unexpected deaths at Glendale Adventist Medical Center raised alarms about the possible foul play involving a healthcare worker. Initially viewed as unfortunate outcomes due to chronic illnesses, the sudden decline and passing of patients like Salbi Esatrian and Eleonora Schlegel sparked rumors of intentional killings through IV injections. Witnesses began to report sightings of unusual behavior in one respiratory therapist, Efren Saldivar, who supposedly had a reputation among staff for causing patients to die more swiftly than others. Despite the alarming gossip, hospital investigations failed to find definitive evidence pointing to a killer among the staff until further reports prompted police involvement months later.
