(Portland, OR) -- A months-long manhunt for a suspect in a Washington murder is now in custody. Raphael Smith, who's accused in the robbery and murder of 41-year-old Kevin Young, was arrested Wednesday by U.S. marshals in Portland. Authorities believe Smith shot Young to death in August at a Tacoma motel. The U.S. Marshals Service says Smith had assumed the identity of a man from the Dominican Republic while in Portland.
