DETROIT (AP) -- Jack Kevorkian, the retired pathologist who captured the world's attention as he helped dozens of ailing people commit suicide, igniting intense debate and ending up in prison for murder, has died in a Detroit area hospital after a short illness. He was 83.
Kevorkian, who said he helped some 130 people end their lives from 1990 to 1999, died about 2:30 a.m. at William Beaumont Hospital in Royal Oak, close friend and prominent attorney Mayer Morganroth said.
He had been hospitalized since last month with pneumonia and kidney problems, Morganroth said.
An official cause of death had not been determined, but Morganroth said it likely will be pulmonary thrombosis.
"I had seen him earlier and he was conscious," said Morganroth, who added that the two spoke about Kevorkian's pending release from the hospital and planned start of rehabilitation. "Then I left and he took a turn for the worst and I went back."
Nurses at the hospital played recordings of classical music by composer Johann Sebastian Bach for Kevorkian before he died, Morganroth said.
Kevorkian was freed in June 2007 after serving eight years of a 10- to 25-year sentence for second-degree murder. His lawyers had said he suffered from hepatitis C, diabetes and other problems, and he had promised in affidavits that he would not assist in a suicide if he was released.
In 2008, he ran for Congress as an independent, receiving just 2.7 percent of the vote in the suburban Detroit district. He said his experience showed the party system was "corrupt" and "has to be completely overhauled from the bottom up."
His life story became the subject of the 2010 HBO movie, "You Don't Know Jack," which earned actor Al Pacino Emmy and Golden Globe Awards for his portrayal of Kevorkian. Pacino paid tribute to Kevorkian during his Emmy acceptance speech and recognized the world-famous former doctor, who sat smiling in the audience.
Pacino said during the speech that it was a pleasure to "try to portray someone as brilliant and interesting and unique" as Kevorkian and a "pleasure to know him."
Kevorkian himself said he liked the movie and enjoyed the attention it generated, but told The Associated Press that he doubted it would inspire much action by a new generation of assisted-suicide advocates.
"You'll hear people say, `Well, it's in the news again, it's time for discussing this further.' No it isn't. It's been discussed to death," he said. "There's nothing new to say about it. It's a legitimate ethical medical practice as it was in ancient Rome and Greece."
Eleven years earlier, he was sentenced in the 1998 death of a Lou Gehrig's disease patient - a videotaped death shown to a national television audience as Kevorkian challenged prosecutors to charge him.
"The issue's got to be raised to the level where it is finally decided," he said on the broadcast by CBS' "60 Minutes."
Nicknamed "Dr. Death" because of his fascination with death, Kevorkian catapulted into public consciousness in 1990 when he used his homemade "suicide machine" in his rusted Volkswagen van to inject lethal drugs into an Alzheimer's patient who sought his help in dying.
For nearly a decade, he escaped authorities' efforts to stop him. His first four trials, all on assisted suicide charges, resulted in three acquittals and one mistrial.
Murder charges in earlier cases were thrown out because Michigan at the time had no law against assisted suicide; the Legislature wrote one in response to Kevorkian. He also was stripped of his medical license.
People who died with his help suffered from cancer, Lou Gehrig's disease, multiple sclerosis, paralysis. They died in their homes, an office, a Detroit island park, a remote cabin, the back of Kevorkian's van.
Kevorkian likened himself to Martin Luther King and Gandhi and called prosecutors Nazis, his critics religious fanatics. He burned state orders against him, showed up at court in costume, called doctors who didn't support him "hypocritic oafs" and challenged authorities to stop him or make his actions legal.
"Somebody has to do something for suffering humanity," Kevorkian once said. "I put myself in my patients' place. This is something I would want."
Devotees filled courtrooms wearing "I Back Jack" buttons. But critics questioned his publicity-grabbing methods, aided by his flamboyant attorney Geoffrey Fieger until the two parted ways before his 1999 trial.
"I think Kevorkian played an enormous role in bringing the physician-assisted suicide debate to the forefront," Susan Wolf, a professor of law and medicine at University of Minnesota Law School, said in 2000.
"It sometimes takes a very outrageous individual to put an issue on the public agenda," she said, and the debate he engendered "in a way cleared public space for more reasonable voices to come in."
Even so, few states have approved physician-assisted suicide. Laws went into effect in Oregon in 1997 and Washington state in 2009, and a 2009 Montana Supreme Court ruling effectively legalized the practice in that state.
In a rare televised interview from prison in 2005, Kevorkian told MSNBC he regretted "a little" the actions that put him there.
"It was disappointing because what I did turned out to be in vain. ... And my only regret was not having done it through the legal system, through legislation, possibly," he said.
Kevorkian's ultimate goal was to establish "obitoriums" where people would go to die. Doctors there could harvest organs and perform medical experiments during the suicide process. Such experiments would be "entirely ethical spinoffs" of suicide, he wrote in his 1991 book "Prescription: Medicide - The Goodness of Planned Death."
His road to prison began in September 1998, when he videotaped himself injecting Thomas Youk, a 52-year-old Lou Gehrig's disease patient, with lethal drugs. He gave the tape to "60 Minutes."
Two months later, a national television audience watched Youk die and heard Kevorkian say of authorities: "I've got to force them to act." Prosecutors quickly responded with a first-degree murder charge.
Kevorkian acted as his own attorney for most of the trial. He told the court his actions were "a medical service for an agonized human being."
In his closing argument, Kevorkian told jurors that some acts "by sheer common sense are not crimes."
"Just look at me," he said. "Honestly now, do you see a criminal? Do you see a murderer?"
