Thirty-four-year-old Democratic Rep. Jose Miranda and 28-year-old Michelle Wilson are charged with perjury, criminal conspiracy and conflict of interest. A preliminary hearing is scheduled Feb. 4.

Prosecutors allege that he funneled a public salary to his sister through a ghost worker because state ethics rules barred her from being on the payroll.

A grand jury said Wilson received part of the $36,000 annual salary paid to Timothy Duckett. He held the title of legislative assistant but apparently never showed up at district offices, working instead at an auto repair shop.
