TOLEDO, Ohio (AP) — A serial killer known as the "Angel of Death" after he admitted killing three dozen hospital patients in Ohio and Kentucky during the 1970s and '80s was beaten in his cell and is in critical condition, state authorities said Wednesday.
Donald Harvey, who is serving multiple life sentences, was found in his cell Tuesday afternoon at the state's prison in Toledo, said JoEllen Smith, spokeswoman for Ohio's prison system.
While details about his injuries weren't released, the State Highway Patrol said he was in critical condition Wednesday.
He was beaten after an unnamed person went into his cell, a patrol report said.
Harvey, 64, pleaded guilty in 1987 to killing 37 people, mostly while he worked as a nurse's aide at hospitals in Cincinnati and London, Kentucky. He later claimed he was responsible for killing 18 people while working at the Veterans Administration Medical Center in Cincinnati.
He told his former attorney the killings began in 1970 when was at Marymount Hospital in Kentucky.
Many of his victims were chronically ill patients and he claimed he was trying to end their suffering.
Harvey used arsenic and cyanide to poison most of his victims, often putting it in the hospital food he served them, prosecutors said. Some of the patients were suffocated when he let their oxygen tanks run out.
He was caught after a medical examiner smelled cyanide while performing an autopsy on a victim.
Harvey told a newspaper after he pleaded guilty to avoid the death penalty that he liked the control of determining who lived and died.
This story has been corrected to show that Harvey pleaded guilty to 37 murders, not 35.
