The town of Windsor has requested that a grand jury get involved in the investigation of Mayor Dominic Foppoli. Officials made the formal request yesterday as they move forward with their bid to recall Foppoli, who has been accused of sexual assault by at least seven women. The Sonoma County District Attorney Jill Ravitch had recused her office from the investigation after Esther Lemus, a deputy prosecutor in Ravitch’s office, accused Foppoli of sexual assault.
