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.

San Jose fire investigators on Monday inspected the exterior of the heavily-damaged Almaden Valley post office.
