Jack Kevorkian's attorney is asking Michigan's governor and parole board for a third time to pardon the 77-year-old assisted-suicide advocate or commute his sentence.

Kevorkian is eligible for parole in 2007, but attorney Mayer Morganroth says he might not live that long. Kevorkian suffers from a number of ailments, including high blood pressure, arthritis, cataracts, osteoporosis and Hepatitis C, he said.

"The man is in dire shape," Morganroth said in a statement Saturday. "Prison has deteriorated him almost to the point of no return."

Gov. Jennifer Granholm has said in the past that she won't consider pardoning Kevorkian. Two previous requests with parole board, in 2003 and 2004, were denied, Morganroth said.

Kevorkian is serving a 10- to 25-year sentence for second-degree murder for giving a fatal injection of drugs to Thomas Youk in 1998, a death that was videotaped and shown on CBS' "60 Minutes."

Youk, 52, had Lou Gehrig's disease, and Kevorkian called his death a mercy killing.

Kevorkian has said he assisted in at least 130 deaths, but has since promised not to assist in more suicides if he is released from prison.
