Jasmen Gonzalez was last seen at about 11:45 Saturday night. She and her parents are from Oklahoma City and were visiting relatives at an apartment complex in the 1300 block of Walnut Street, near the intersection of Belt Line Road and Interstate 35E.
Police said Jasmen might have wandered out of the house after going to bed. She is unfamiliar with the area.
The Dallas police helicopter, a Child Abduction Response Team and the FBI have all joined in helping Carrollton police search for the missing child. A Carrollton police spokesperson said while they are involved in many cases of missing children, this one is "unique."
