The “independent” law firm that Fairfax County Public Schools hired to investigate its handling of a groping case involving an illegal immigrant provides pro bono immigration assistance and coaches clients on how to elude deportation authorities.

Earlier this year, FCPS retained McGuireWoods, the largest law firm in Virginia, as an “objective” investigator to review whether the Northern Virginia school district properly dealt with a string of sexual assaults on school property committed by now-convicted illegal immigrant Israel Flores Ortiz.
