FBI raids Contra Costa tax office and homes amid wire fraud probe

The FBI executed three search warrants in Contra Costa County, including the Martinez tax assessor's office and the homes of the current and outgoing tax assessors, amid allegations of wire fraud and other offenses. Authorities have not disclosed what they sought; the warrants cite possible wrongdoing connected to property valuations. Long-time assessor Gus Kramer and incoming official Vince Robb are linked to the case, with Robb set to take office in January.
