An attorney for Jack Kevorkian said the assisted-suicide advocate will probably not survive another year if kept in prison, as he again asked the state to grant his client a pardon or commute his sentence.

Lawyer Mayer Morganroth said he applied to the state Parole Board and Gov. Jennifer Granholm on Friday seeking a pardon, parole or commutation, citing the 77-year-old's deteriorating health.

"Kevorkian has become increasingly frail and has fallen twice, injuring his wrist and fracturing two ribs," Morganroth said in a statement.

The former doctor is serving a 10- to 25-year sentence for second-degree murder for giving a fatal injection of drugs in 1998. He is eligible for parole in 2007.

In 2003, 2004 and 2005, Granholm followed the parole board's advice in denying applications for a commuted sentence or a pardon.

Kevorkian has said he assisted in at least 130 deaths, but has promised that he will not assist another if released.
