The FBI is now offering a $200,000 reward for information leading to the arrest of a man sought for a 2004 Arizona robbery in which an armored car guard was killed.
The original reward for Jason Derek Brown was $100,000.
He's sought for the killing of Robert Palomares, the guard who was gunned down as he left a Phoenix movie theater with more than $56,000 in cash.
An Arizona warrant charges Brown with first-degree murder and armed robbery. A federal warrant charges him with unlawful flight to avoid prosecution.
"The last sighting that we have that was credible was up in Portland. The exact timeframe there was shortly after the incident had occurred, but it has been several years really that we have had any credible evidence of location," said FBI Special Agent Mark Hoffman.
Brown was added to the FBI's most-wanted list in 2007.
