Barren County authorities are trying to decide how to prosecute a convicted murderer in Indiana who confessed to the 1998 killing of a Kentucky woman.

Barren County Sheriff Chris Eaton says 35-year-old David M. Bell admitted to killing 42-year-old Nancy Daddysman in a four-hour interview this week.

Bell is serving a 63-year sentence for the 2005 murder of Claire Ellis in the Indiana State Prison in Michigan City, Ind.

Officials say he is also a suspect in an Arkansas case.

Daddysman's body was found two years after she went missing, partially wrapped in a piece of upholstery fabric just outside a cave off Iron Mountain Road near Park City.

The Bowling Green Daily News reports Bell is ineligible for parole until 2037.
