BOISE - Convicted child killed and rapist Joseph Duncan is en-route to Riverside, Calif., after being extradited by California prosecuting officials.

Duncan was taken into custody in Riverside County Friday morning.

In February 2007, California Governor Arnold Schwarzenegger made a plea to Idaho Gov. Butch Otter to have Duncan come back California to stand trial for allegedly killing 10-year-old Anthony Martinez who was kidnapped from a neighbor's home in Beaumont, Calif., in 1997.

Riverside County District Attorney, Rod Pacheco, said last summer he was eager to try him.

"He's the worst of the worst and we aim to prove that," Pacheco said. "He's not getting away with this. He's not and it doesn't matter what he does, he's coming back to Riverside County and we're going to prosecute him and seek the death penalty."

Authorities believe Martinez was abducted at knife point from Beaumont and murdered. Authorities believe the abductor was Duncan.

"This is a monster who preys on those most vulnerable in our society, children," Pacheco said.

Duncan was convicted of kidnapping Shasta Groene, then eight years old, and her brother Dylan, 9, from their Northern Idaho home in May 2005, and shooting Dylan to death at a campground in western Montana.

Duncan received the death penalty for those crimes.
