Former suburban Philadelphia multimillionaire John du Pont has lost a bid for parole.

A jury in 1997 found the heir to his family's chemical company fortune guilty of third-degree murder but mentally ill in the 1996 shooting death of Olympic gold medal-winning wrestler David Schultz.

Du Pont was sentenced to 13 to 30 years in prison, but first was treated for three months at Norristown State Hospital.

His attorney, Tara Wochok, says the 70-year-old du Pont is now at the state prison at Mercer in western Pennsylvania. Wochok says du Pont's parole petition was turned down last month.

Delaware County District Attorney Michael Green says that was because of the brutal way in which Schultz died, and because du Pont has not taken responsibility or shown remorse.
