Family members say they are suspicious about the way the cousin of a 2-year-old girl told authorities the child went missing from outside a northwestern Indiana convenience store.

Authorities continued a search Thursday for 2-year-old Jada Justice of Portage. The search began when 18-year-old Angelica Castillo told Gary police the child was gone when she returned to the car Tuesday night after buying a gallon of milk.

Gary police Cmdr. Anthony Titus says Castillo was being held as a person of interest, but she doesn’t appear to have done anything to do with the toddler's disappearance. The girl's uncle, Mike Valdez, says he doesn't understand why search dogs could not pick up Jada's scent if she had just been in the car seat.
