Canine units gave police a clue today that sent them in a "new direction" in the search for missing Arizona 6-year-old Isabel Mercedes Celis—a direction that led them to ask Isabel's family to leave the home from which she allegedly disappeared over the weekend, police tell NBC. Authorities didn't specify what that new direction was; the local police chief tells NBC that they have more than 100 leads in the case, but that they're not "closing our mind to any possibility."
"We don't have an actual piece of evidence that points us in one direction or another," a police spokesman tells ABC. "For example, we don't have a piece of evidence that says she was definitively taken from the residence." The police chief did, however, confirm that Isabel's bedroom had a window, and that the screen had been removed. He also said officers had served at least two search warrants, in addition to searching the local landfill and transit station. (Read more Isabel Mercedes Celis stories.)
