Federal agents executed search warrants Tuesday at the Contra Costa County Assessor's Office in Martinez and two East Bay residences as part of an ongoing investigation, the FBI confirmed. The searches targeted the assessor's office, a home in Martinez, and a property in nearby Pacheco, all linked to outgoing Assessor Gus Kramer and Assistant Assessor Vince Robb, who won the June 2 election to succeed Kramer.
According to the San Francisco Chronicle, citing the Mercury News, one warrant sought evidence of wire fraud and other potential crimes. The warrant was signed by a federal magistrate judge on June 4.
No arrests or charges have been announced, and authorities have not identified any specific targets. The assessor's office determines taxable property values across Contra Costa County, which directly affect property tax bills and funding for local governments, schools, and special districts.
Robb won the election with over two-thirds of the vote and is set to replace Kramer, who has served as assessor since 1994 and is retiring at the end of his term. The FBI has not released further details.
