Search on for Tucson Girl, 6

Tucson law-enforcement officers scoured the city Sunday for 6-year-old Isabel Mercedes Celis, who was last seen Friday. Close to 100 officers are looking for the first grader in a case that police have said may involve a kidnapping. While Celis’s friends and family have fanned out with fliers in their Arizona neighborhood, police combed the city’s east side with helicopters and bloodhounds. The police also searched the girl’s home, where she lives with both of her parents, for signs of a possible break-in, and a police spokesman said the case is being treated as a “possible abduction.”
