While police are investigating their disappearance, the girl’s father is afraid they may have run away. However, he does find it unusual the girl’s left their glasses behind, reported NBC 4 Washington.

"They left with nothing," Ramon Matos, the girls' father told NBC 4. "They've got nothing with them. They got no money, no clothes, nothing."
