Aliayah Lunsford, 3, of Weston, disappeared September
24, and has been the object of a widespread search.

FBI Special Agent Jeff Killeen said Friday the FBI is narrowing its focus of the investigation and has a specific timeline of events.

He also said the chances of finding the toddler alive is very slim.

Killeen said the FBI is combing through a lot of photographic and video surveillance evidence. Officials are using digital enhancement techniques and they have captured a lot of video from homes and businesses in the south Weston neighborhood.

Killeen said that more than one person could been involved and did not rule out a "conspiracy."

The FBI says the missing child is either a kidnapping, concealment or homicide and are considering filing both federal and state charges.
