Ola May Redenbarger was an 85-year-old White woman who died at Vermillion County Hospital in Clinton, Indiana, on November 22, 1994, under suspicious circumstances. Her death came during a sharp rise in patient mortality at the small rural hospital between 1993 and 1995 that later became the focus of a criminal investigation tied to a licensed practical nurse employed there.

Investigators found the hospital’s death rate climbed dramatically during the nurse’s shifts; an epidemiologist testified a patient was nearly 43 times more likely to die when he was on duty. Exhumations and toxicology testing identified lethal injections of potassium chloride and epinephrine in multiple victims. Prosecutors later linked the pattern to Orville Lynn Majors; he was arrested in December 1997 and ultimately convicted in 1999 on multiple murder counts and sentenced to 360 years in prison.
