ST. PAUL, Minn. (AP) — A Guatemalan woman who was deported after she was convicted in a 2008 school bus crash that killed four children in southwestern Minnesota pleaded guilty Monday to illegally re-entering the United States, federal prosecutors said.

Olga Marina Franco del Cid, 36, pleaded guilty to one count of illegal re-entry after removal and one count of false representation of a Social Security number, the U.S. Attorney’s office said. Sentencing is scheduled for June 11.

Franco del Cid was arrested in November by federal immigration officers after they received a tip that she returned to the U.S. and was back in Minnesota.

Franco del Cid was convicted of criminal vehicular homicide after crashing a minivan into a school bus near Cottonwood in 2008, killing four students. She served eight years of her sentence and was deported after being released from state prison.
