ORANGE PARK, Fla. (AP) - A daylong search for a missing 7-year-old North Florida girl who vanished on her way home from school has produced more than 150 leads, but the child remained missing.

More than 100 Clay County deputies, law enforcement officers from neighboring counties, the FBI and the Florida Department of Law Enforcement scoured the residential Orange Park neighborhood Tuesday looking for Somer Thompson.

Sgt. Dan Mahla, a Clay County detective, said horses, dogs, divers and helicopters have been used in the search, which began Monday afternoon when the child failed to return home from school.

Officials have no idea what happened to the child, but Mahla says they believe it is foul.

The Amber Alert was issued at 9 a.m. Tuesday by the Florida Department of Law Enforcement.
