George Shirakawa Jr. can no longer afford his legal bills, according to his top-dollar lawyer. As a result, county taxpayers will now start picking up the tab. In court Wednesday, attorney John Williams told Judge Risë Jones Pichon that the disgraced former county supervisor needs a public defender to represent him on a felony charge of false personation. That case, as well as a sentencing hearing for Shirakawa’s admitted misuse of campaign funds and perjury, will be heard next week.
