Cristian Romario Saenz-Argueta, a 31-year-old noncitizen from El Salvador, was arrested after an investigation into reports that he sexually assaulted a girl under 15 in a parking lot in November 2025. He is charged with three felony counts including rape and carnal knowledge of a child. According to authorities, Saenz-Argueta used social media to connect with the victim, falsely portraying himself as 18 years old before arranging an in-person meeting where the assault occurred. ICE lodged an immigration detainer against him, claiming he entered the U.S. without legal documentation. DHS used the case to criticize Virginia's sanctuary policies and the expiration of Prince William County's 287(g) agreement with ICE.
