Authorities on Wednesday evening issued an Amber Alert for 2-year-old Jason, 3-year-old Aaliyah and 5-year-old Isac Frausto. They were searching for the children's biological mother, 24-year-old Doris Camerena, in connection with their disappearance.
Camerena was last seen in Houston and was said to have been driving a 2011 Chevy Cruz LT with license plate FGJ6333. Her mother has legal custody of the children.
"She took them for pizza but didn't come back. It is sad not having them here. She's their mother, so I don't think they are in too much danger, but I want them back here," the children's grandmother told ABC13.
