More than a thousand pages of documents have been released in the state's case against Casey Anthony, the central Florida mother charged in her daughter's death.

Among the information released Thursday were reports of unconfirmed Caylee Anthony sightings; FBI requests for polygraph tests of witnesses; and records of Casey's ex-fiance, who was enrolled in the police training program but resigned in 2008 for personal reasons.

There are also interview transcripts with the grandparents, which are not new.

Caylee's remains were found in woods near her family's home in December. Casey Anthony has pleaded not guilty and says a baby sitter kidnapped Caylee.

Casey's brother is being questioned under oath Thursday by prosecutors about the murder case.
