BOISE, Idaho (AP) - Joseph Edward Duncan III, convicted and sentenced to death for the kidnapping, torture and slaying of a northern Idaho boy, has been transferred to a federal death row prison in Indiana.

Duncan, 45, was given three death penalty sentences last year for the 2005 kidnapping, sexual abuse and torture of Dylan Groene, 9, and his 8-year-old sister Shasta, along with Dylan's murder.

He snatched the children from the Coeur d'Alene home after killing their brother, mother and her fiance.

Duncan had been incarcerated in the Ada County Jail, but is now at the federal prison in Terre Haute, Ind., according to the Federal Bureau of Prisons.

Defense lawyers are appealing his death sentences in the 9th U.S. Circuit Court of Appeals.

Meanwhile, prosecutors in Riverside, Calif., say they are working to bring Duncan back to be tried for the abduction and slaying of a 10-year-old boy in 1997.
