The United States Postal Service building in the 6500 block of Crown Boulevard in South San Jose is temporarily closed after sustaining major damage from a vehicle that was driven into the facility early Sunday morning.

The brother of the late NFL player and U.S. Army Ranger Pat Tillman is suspected of driving into a South San Jose post office early Sunday morning, officials said.

The U.S. Postal Service is now leading the investigation and told KPIX-TV that Richard Tillman is the brother of Pat Tillman. U.S. Postal Inspector Matthew Norfleet told the outlet that the motive for the alleged arson is under investigation. Photos from the scene show the words “Viva la me” were spray-painted on the front of the building.
