ORLANDO, Fla. -- About 1,500 pages of new information have been released in the search for Caylee Anthony, whose mother, Casey, reaffirmed her not guilty plea in her daughter's disappearance.

Thousands of tips called in to investigators about the missing 3-year-old, who was last seen in mid-June but was not reported missing until a month later, were released on Tuesday.

The majority of the tips reviewed by Local 6 News were submitted by seers and psychics, who phoned in visions and dreams.

Some of the tips included photographs of where to search, while others were very vague.

None of the tips reviewed by Local 6 News involved a sighting of Caylee being alive.

Anthony's attorney, Jose Baez, requested the information two weeks ago to help prepare his case.

Trial Date Set

Meanwhile, Casey Anthony reaffirmed her not guilty plea at an arraignment on Tuesday and will stand trial, which is scheduled to start Jan. 5.

Casey Anthony was not present at the arraignment on Tuesday. The 22-year-old had entered a written not guilty plea on Oct. 17 to a charge of first-degree murder.

Casey Anthony said she left Caylee with a baby sitter. The girl has not been found.

Attorney: Evidence Weak At Best

A veteran defense attorney on Monday said the evidence in the case is weak at best.

Attorney Diana Tennis said she is not sure the state's case against Anthony is solid.

"There's a big difference between interesting science evidence and evidence that actually gets to a jury," Tennis said.

Authorities on Friday released a report from a Tennessee lab that found five compounds consistent with body decomposition. Tests found evidence of decomposition on a hair strand found in the trunk, described as "microscopically similar" to one found on Caylee's hair brush.

"This whole talk about the 'body farm' and these interesting tests that this one organization is doing is very, very fascinating. It may be good information, but it's also possible that the jury is never going to hear about it," Tennis said.

Tennis cited the example of lie-detector tests, which law enforcement agencies consider credible but courts do not.

"No matter how good the science may be, that doesn't mean the judge is going to let the jury hear about it if it's not completely trustworthy," Tennis said.

Anthony Family Attends Ceremony

Caylee's grandfather, George Anthony, said a ceremony held for missing children at Florida's Capitol was "gut-wrenching."

George and his wife, Cindy Anthony, joined 13 other families and Gov. Charlie Crist at the annual Missing Children's Day commemoration Monday. Cindy Anthony said the other families in attendance offered comfort and inspiration.

Cindy Anthony said her family continues to believe Caylee is alive.

A national search for Caylee continues.
