Prosecutors have filed federal charges against the woman accused of causing a fatal school bus crash near Cottonwood in southwestern Minnesota.

Twenty-four-year-old Olga Marino Franco del Cid is charged in federal court with two counts of aggravated identity theft and two counts of false representation of a Social Security number.

Prosecutors allege she gave authorities a false name and Social Security number after the crash February 19th, when four students were killed when a van she drove crashed into their school bus.
