Sandra, a native Honduran, was with a group crossing the Rio Grande River to enter into the United States from Mexico on June 4, 1989. Her brother stated that she made it across safely but was left behind by the group. She has family members in the Brownsville, Texas area, but she never contacted them after her supposed entry. She has not been seen again. Some agencies may list December 1, 1991 as the date of her disappearance.
