TUCSON, AZ - Tucson police say they still haven't eliminated any possibilities as the search for a missing first-grader enters its third week.
At a media briefing Saturday police said that investigators looking into the disappearance of 6-year-old Isabel Mercedes Celis have fielded about 900 leads since she was last seen. Police say they don't have any reason to believe Isabel isn't alive.
Sergio and Becky Celis say they last saw Isabel in her room the night of April 20th.
Police say investigators are still looking at every possibility and no one is a focus of the investigation, and no one has been eliminated either. Detectives and analysts are working through the weekend on the case.
