MARTINEZ — Agents from the Federal Bureau of Investigation raided the house of a professional baseball team’s owners on Tuesday morning, the agency confirmed.

Witnesses said that at least 20 agents came to a home in the 5300 block of Stonehurst Drive that is registered to Jeff and Paulette Carpoff, the listed owners of the Martinez Clippers. The Clippers in August finished their inaugural season in the Pacific Association of Professional Baseball Clubs.

The agency confirmed that it executed search warrants on the home but did not comment on any other aspect of their investigation.

Jeff Carpoff also is listed as the Chief Executive Officer of DC Solar Solutions, Inc., a Benicia-based solar company.

Multiple witnesses on Wednesday watched the agents tow away vehicles. FBI officials would not discuss what they seized from the home.

A source with close knowledge of the investigation said agents also removed computers, cell phones and receipts.

Calls to numbers listed as belonging to the Carpoffs went unanswered on Thursday.
