ClickOrlando.com: ORLANDO, Fla. -- The state attorney's office on Thursday released more than 1,400 pages of new documents in the Casey Anthony case.

Anthony, 23, remains jailed on first-degree murder charges in the death of her daughter, Caylee, whose remains were found in December. Caylee was 2 years old when she was reported missing last July.

According to one of the documents, Casey Anthony's attorney, Jose Baez on March 19, 2009, turned over a box full of items to the FBI. Among the items in the box were a Spiderman toothbrush, Tylenol drops, three children's books, toy food and utensils, a pillow case, a bed sheet and a pink hat.

The defense team also gave the FBI an umbilical cord, presumably for DNA testing.

Hair samples from Casey and Caylee Anthony, and Casey's mother, Cindy Anthony, as well as DNA swabs from Casey Anthony were also provided, the documents show.

It's unclear why the items may be significant or why they were handed over to the FBI just a few months ago.

The defense also presented a four-page report entitled "independent forensics DNA testing and technologies." It's not know if the report was put together by Casey Anthony's defense team.

The documents also show that Cindy Anthony tried to provide detectives with proof that the mysterious baby sitter Zenaida Gonzalez existed.

Shortly after Caylee's disappearance, Cindy Anthony gave investigators several items that the baby sitter would have likely touched, such as toys and DVDs that Caylee reportedly took to Gonzalez's house.

The Orange County Sheriff's Office tested the items for fingerprints, but the results are unknown.

Investigators, however, have repeatedly said that the baby sitter does not exist.

Of the 1,400 pages released, about 700 of them involved a public-records request made by Local 6 News investigative reporter Tony Pipitone more than a year ago of the Orlando Police Department.

The documents show the work history of former probationary police Officer Jesse Grund, the one-time fiance of Casey Anthony.

The records show that other officers were sometimes not comfortable with Grund's performance prior to his resignation for personal reasons in June 2008 -- the month Caylee disappeared.

Also released was a letter from the FBI confirming that Casey Anthony's family -- parents George and Cindy Anthony and her brother, Lee Anthony -- declined to take polygraph tests.

Other documents show reports of unconfirmed Caylee sightings. There are also interview transcripts with the grandparents, which are not new.

Meanwhile, Lee Anthony, was deposed by prosecutors on Thursday, and likely faced questions about the days leading up to Caylee's disappearance.

Local 6 News reported that prosecutors are trying to get a better idea of the kind of witness Lee Anthony will be on the stand and whether his testimony would be more beneficial to the defense or the prosecution.

Prosecutors will also try to see if there will be any inconsistencies in Lee Anthony's statements.

Lee Anthony's attorney, Thomas Luke, said nothing his client says will be used against him because in the days after Caylee was reported missing, Lee Anthony spoke to his sister several times, with many of the conversations recorded on jailhouse video.

"He would have use immunity for this deposition. He's already received his subpoena, so I'm unconcerned that they would prosecute him for any sort of perjury or anything else like that," Luke said.

Local 6 News reported that Casey Anthony's father, George Anthony, will likely be deposed next week.

Casey Anthony's trial will not begin until 2010.
