"I hope if I'm ever sick and full of tubes or on a respirator, someone will come and end it", Harvey told reporters in 1987. A patrol report said the 64-year-old was beaten when an unnamed person entered his cell. His death stemmed from injuries he suffered during an attack two days earlier.
A U.S. serial killer known as the "Angel of Death" has died two days after being found beaten in his Toledo prison cell.
He quit Marymount Hospital on March 27, 1971 for undisclosed reasons, but in the 10 months that Donald Harvey worked there, he killed 15 people. "I felt what I was doing was right".
He claimed, however, to have killed 87 people - a total that included not just patients or the terminally ill who were under his care in hospital settings, but roommates, neighbors, and lovers, according to a detailed summary of his background and alleged murders compiled by researchers at the Radford University Department of Psychology.
Twenty-one of the people Harvey killed were patients at the former Drake Memorial Hospital in Cincinnati, where he worked as a nurse's assistant. Arther Ney Jr, the OH prosecutor who handled the case in 1987, told the court.
He agreed to a plea deal that allowed him to avoid the death penalty and is serving multiple life sentences.
Harvey used arsenic and cyanide to poison most of his victims, often putting it in the hospital food he served them, prosecutors said.
Others were suffocated in their hospital beds, either with their pillows or by oxygen tanks that he refused to refill.
Former Hamilton County Prosecutor Arthur Ney Jr., who prosecuted the cases in Cincinnati, said Harvey was not a mercy killer. A serial killer known as the "Angel of Death" after he admitted killing three dozen hospital patients in Ohi.
He was caught after a medical examiner smelled cyanide while performing an autopsy on a victim.
He would have been eligible for parole in 2043 at 91 years old. During his confession, Harvey said Powell had been one of two patients he had killed that day. He was convicted of killing 36 people between 1970 and 1987. After that, the bodies would typically go straight to the funeral home.
Donald Harvey, the so-called "Angel of Death", died on Thursday, March 30, 2017 after a vicious attack in his OH state prison cell. Harvey had allegedly killed almost 50 people between 1976 and 1988 before he was finally caught and put on trial for his crimes.
No charges had been filed as of Friday afternoon and the name of the suspect hasn't been released, said Lt. Robert Sellers, a State Highway Patrol spokesman.
