The state Comptroller’s Office has agreed to work with the Ulster County District Attorney’s Office to investigate the Kingston Fire Department. District Attorney Holley Carnright said he spoke directly with state Comptroller Thomas DiNapoli in requesting the assistance and that DiNapoli agreed to assign a state auditor to the case.The investigation comes in the wake of Kingston Mayor Shayne Gallo announcing within the last month that he had asked Carnright’s office to investigate the city’s two most recent fire chiefs — Chris Rea and Richard Salzmann — over “time in attendance” issues.
