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.
Brown was added to the FBI's most-wanted list in 2007.
