On April 16, 1990, "Doctor Death" Jack Kevorkian began his campaign of assisted suicide, sparking an ethical debate over the practice of physician-assisted suicide and a terminal patient's right to die. Dr. Kevorkian claimed to have assisted in over 130 patient suicides, where he famously stated that "dying is not a crime." In 1999, he was arrested and tried for playing a direct role in a case of voluntary euthanasia. He was convicted of second-degree murder and served eight years of a 10-to-25-year prison sentence. Dr. Kevorkian died in 2011 at the age of 83.
