The "Angel of Death" serial killer, who admitted to killing three dozen hospital patients in OH and Kentucky during the 1970s and '80s, has died after being attacked in his prison cell.
Harvey was rushed to hospital after being found badly beaten in his cell on Tuesday (28 March) by staff at Toledo prison.
It's believed that Harvey began the killing spree on May 30, 1970, by smothering an 88-year-old patient with a pillow after he smeared feces on Harvey's face.
The State Highway Patrol says Harvey was in critical condition Wednesday. A patrol report said the 64-year-old was beaten when an unnamed person entered his cell.

But James Tyree, of Louisville, Kentucky, says "maybe the good Lord gave him what he deserved".
Harvey pleaded guilty to 28 counts of murder in OH in a deal that spared him the death penalty.
According to the New York Daily News, Harvey had worked at hospitals where he may have killed as many as 87 people over an 18-year period in the "70s and '80s".
But numerous killings involved his two favorite poisons, arsenic and cyanide, which he would administer in food, using injections, or through an IV.
Harvey admitted those Drake killings and a dozen others to escape the death penalty. Others he suffocated by letting their oxygen tanks go empty.
Donald Harvey killed at least three dozen people while working as a nurse's aide in the 1970s and 80s.
U.S. District Judge Edwin Kosik, who recently stopped hearing cases because of health problems, takes medication for memory problems, and investigators said that might have prompted his disappearance in northeastern Pennsylvania late Tuesday.
He said he was a mercy killer - putting patients out of their misery - but he also said the first patient he killed had just made him angry.
