The issue drew attention in September, when 4-year-old Larissa Guajardo, a U.S. citizen, died of heart problems after crossing the Hidalgo-Reynosa international bridge on the way to a hospital. Family members blamed a delay caused by immigration officials, who would not let the mother enter the country. The mother lacked paperwork and had crossed the border illegally before.TRANSLATION: Mommy made it across the border illegally, and had the child on US soil so she could then use her position as the child's guardian to petition herself into the USA legally.
