The man calls himself Clark Rockefeller, but his real name is Christian Karl Gerhartsreiter.
The L.A. Sheriff's Department says Rockefeller is en route from Boston, where he was serving a prison sentence for kidnapping.
He was charged in March with killing 27-year-old John Sohus of San Marino in 1985. Sohus' body was discovered nearly a decade later.
An investigation determined he was killed by blunt force trauma to the head. Sohus' wife, Linda, is still missing.
Authorities won't disclose which jail he will be sent to due to safety reasons. He is due in a Alhambra courtroom Friday and is being held on $10 million bail.
