The District Attorney’s investigation into George Shirakawa Jr. has some new paperwork to add to the pile, as discrepancies may have been found Monday in forms the former county supervisor filed during and after his time as a member of the San Jose City Council in the late 90s and early 2000s. The City Clerk’s Office began making copies of forms for the DA when San Jose Inside’s inspection of “Friends for George Shirakawa Jr.” campaign forms found inconsistent signatures from previous campaign treasurers Shirakawa employed for his 1998 council re-election campaign and officeholder account.
