TUCSON, Arizona (AP) - Tucson police say they still haven't eliminated any possibilities as the search for a missing first-grader enters its third week.
Police spokesman Lt. Fabian Pacheco said at a Saturday media briefing that investigators looking into the disappearance of 6-year-old Isabel Mercedes Celis have fielded about 900 leads since she was last seen.
Pacheco says police don't have any reason to believe Isabel isn't alive.
Sergio and Becky Celis say they last saw their youngest child in her room the night of April 20 and discovered her missing the next morning.
Pacheco says detectives are still looking at every possibility and that no one is a focus of the investigation. No one has been eliminated, either.
About 15 to 20 detectives and analysts are working through the weekend on the case.
