Donald Harvey, an Ohio hospital orderly who described himself as an 'angel of death', was sentenced to triple life terms after pleading guilty to poisoning 24 patients. Harvey claimed to have begun killing in 1970 to ease the suffering of the terminally ill, smothering his first victim, 88-year-old Logan Evans, with a pillow at Marymount Hospital in London, Kentucky. His methods expanded to include arsenic, cyanide, morphine, insulin, and suffocation, deployed across multiple hospitals over 17 years.
Harvey ultimately claimed 87 murders, with 37 confirmed victims. To avoid execution, he pleaded guilty and received 28 life sentences in total. He died in custody at Toledo Correctional Institution on March 30, 2017, one of the most prolific hospital killers in American history.
