Tucson police have been joined by FBI agents and a large contingent of deputy U.S. Marshals as they search for a 6-year-old girl who went missing from her house.

Isabel Mercedes Celis was last seen by her parents late Friday and they discovered her missing at about 8 a.m. Saturday.

Sgt. Maria Hawke says police are searching the area of the Arizona city around East Broadway Boulevard and Craycroft Road using street patrols, canines, detectives and a helicopter.

Police say they are investigating all potential scenarios, including the possibility that Isabel got up and wandered out of the home she shares with her parents and two brothers or that she was kidnapped.
