Jack Kevorkian said Tuesday he has a new mission to educate and inform the masses about their rights as citizens following his release from prison.

"My new mission is not assisted suicide," Kevorkian, 79, said during his first news conference since he left prison Friday. "My work is effectively done there. ... I'll do what I can to have it legalized."

The retired pathologist claims to have helped at least 130 people die from 1990 until 1998, the year he was charged with murder in the death of a 52-year-old Oakland County man with Lou Gehrig's disease.

He was convicted and given a 10- to 25-year sentence for second-degree murder. He spent eight years behind bars, earning time off his sentence for good behavior.

Kevorkian has promised not to help in any other assisted suicides, and could go back to prison if he did.
