ORANGE COUNTY, Fla. -- New documents were released Thursday in the case against Casey Anthony that reveal what George and Cindy Anthony told investigators in the hours and days after Caylee Anthony was reported missing.

The State Attorney's Office released 700 pages of new documents in the case Thursday and they show that George Anthony told investigators he felt something was wrong from the very beginning. The documents focus a lot on interviews George and Cindy Anthony did with sheriff's deputies.

When sheriff's investigators questioned Casey's father George nine days after Caylee was reported missing, George told them he had "bad vibes" the very first day he got his car back and smelled the smell in the trunk, a smell, he said as a former law enforcement officer, he knows and would never forget.

Casey's father George told investigators, "I don't want to believe that I have, have raised someone and brought someone in this world that could do something to another person. I don't want to believe that."

George also told them, "I, I, I believe that there's someone dead back there and I hate to say the word human. Um, I hate to say that."

George told them, when he opened the trunk of the car, he said to himself, "Please don't let this be my Caylee."

But Thursday, Cindy told Eyewitness News she's holding on to hope.

"No one's brought me a body. No one's proven that she's dead. I'm not gonna give up on someone that I love that easy. And if I did, then what kind of person would I be? I'm not that person," she said (full interview).

But George also told sheriff's investigators that the very first night they found out Caylee was missing, Cindy told him, "We lost her. We lost her." When he asked who, she said "Caylee."

George also told investigators his daughter Casey lives on the edge, that she takes things as far as she can take them and then she piles on more. He said they caught her in lies about work and money and said she's really good with computers.

Casey spent the Tuesday through Saturday around the 4th of July with Amy Huizenga, her former best friend. She told Amy that Caylee was at the beach with the nanny and with Cindy, but no one's met the nanny.

Amy also told investigators that Casey made up a story that she saw Amy counting money while she was sound asleep. Amy later figured out that $400 was missing and never could find it.

Not only did Casey Anthony lie to her family, friends and investigators, George says she lied to her attorney Jose Baez. She told him she had $5,000, even though she didn't and then she told him that he'd get the rest after she gets out of the situation.

STATE WANTS GAG ORDER, ATTORNEY WANTS TIPS

Prosecutors in the case against Casey filed a motion to "shut up" Jose Baez and the Anthony family (read motion).

The state attorney is asking for a gag order on several key players in the case, saying that attorney Jose Baez has "succumbed to the lure of the national spotlight" and frequently expresses his opinion about the case.

They also accuse the Anthony family of turning every opportunity to talk about Caylee into an attack on the prosecution.

Meanwhile, Baez has filed his own motion, demanding more of the 5,000 tips the sheriff's office collected (read motion). The 450 they've already released were mostly from psychics.

A judge will consider the requests on Monday.

CINDY ANTHONY RELEASES STATEMENT

Cindy Anthony is reacting to defense attorneys' claims that her granddaughter may have died from an accidental overdose.

In a statement released Thursday, she wrote:

"I feel that a good attorney will plan for the worse case scenario and hope for the best. I know that Casey's attorneys know that she is innocent, but they cannot ignore how the media has already spun the facts and convicted her.

"Casey has been severely attacked by the media since she was first arrested, and anyone would be a fool to ignore that. All of the negative spin has done her an injustice. Just look at what it has done for poor Caylee. The media already has given up on looking for this child, when there is simply no credible or concrete evidence to prove that she is dead.

"The defense and the family will never give up on looking for Caylee. We continue to believe she is alive, and so should everyone else who has a conscience. I would ask anyone to ask themselves just how quick would they stop looking for someone that they loved?"

Casey Anthony's attorneys have claimed little Caylee was simply missing. But in a 30-page document to prosecutors, the defense argued if Caylee is dead then it was almost certainly an accident. The change may be a possible attempt to spare their client from the death penalty.

DEFENSE: IF CAYLEE'S DEAD IT WAS ACCIDENT

Publicly, Casey Anthony's defense team has always insisted that Caylee Anthony is alive, even after Casey was arrested and charged with her daughter Caylee's murder.

"We all believe she's alive," attorney Jose Baez said during a hearing at the Orange County Courthouse on Wednesday.

However, Eyewitness News has learned that, behind the scenes, the defense team sent 30 pages of documents to prosecutors. In those documents, Casey's lawyers argued that if Caylee is dead that it was "almost certainly a tragic accident."

The documents also said Caylee could've been poisoned by chloroform or she could have died while she was sedated. They said the cause of death could have been an unwitting overdose of a sedative.

The defense documents went on to describe Casey as troubled and possibly depressed. They said her behavior had been erratic ever since Caylee's birth and particularly in the months before the little girl's disappearance.

Also, the documents state that Casey's lack of emotion after Caylee's disappearance is proof that she is not normal and could possibly be suffering from mental or emotional stress.

The defense used those documents to argue that the death penalty is not an appropriate sentence in Casey's case, because she is young and she's never had a criminal record. However, the documents never mention Casey's story that a babysitter took Caylee and disappeared with her.

Eyewitness News also learned that dissention among the defense team may be behind the release of those documents. The death penalty-qualified attorney, who is helping Jose Baez, said he wanted Casey to be evaluated by a nationally-known psychologist who was involved in the Unabomber and the Elizabeth Smart cases. The attorney thinks Casey is mentally ill, but Eyewitness News learned Baez rejected his suggestion.

The latest development comes after Eyewitness News caught a major slip-up by Casey's defense team on national TV last month, when a spokesperson for her attorney admitted Caylee Anthony was dead.

"This is a very serious case involving not just the life of a little girl, but the loss of whatever is going to happen with Casey Anthony," said Black.

Jose Baez's spokesperson Todd Black made that statement during a phone interview with CNN.

Last week, Baez replaced Black on his defense team with another spokesperson.

EQUUSEARCH BACK IN ORLANDO

Organizers for the Texas based group EquuSearch were back in Central Florida Thursday preparing for the latest search for Caylee Anthony's remains. EquuSearch expects nearly 5,000 people to show up for Saturday's search effort. A former medical examiner, divers, marines, and pilots, everyone they need for any type of search, will be on hand.

It's expected to be the largest search in national history for a single person. An all out effort to find Caylee's body is set to begin this weekend. The search team tried in October to search for the little girl's remains, but Tropical Storm Fay brought too much water and hindered the search efforts.

"Water has receded and vegetation has died off and we think that's going to greatly improve our ability to search the area," said Texas EquuSearch worker Mandy Albritton.

Albritton told Eyewitness News the search team plans on covering 25-square miles of land around the airport. Records show Casey Anthony used her cell phone in that area when her daughter disappeared.

EquuSearch will use horses, ATVs and 3,000 to 4,000 volunteers. The team will build a command center with toilets, sinks and generators at the intersection of Lee Vista Boulevard and Shadowridge Drive.

Eyewitness News reporter Mark Boyle asked if George and Cindy would be participating in the search and the family released the following statement Thursday afternoon in response: "We will not take part in any search for a dead Caylee. We do searches EVERYDAY for a live Caylee."

BOUNTY HUNTER APPEARS ON NANCY GRACE SHOW

California bounty hunter Leonard Padilla told CNN's Nancy Grace that he thinks Anthony's lawyers are creating a defense before EquuSearch resumes their search for Caylee's body on Saturday.

"The notation about if there was a death or if it was accidental doesn't surprise me at all. They know we are going to find the body by Monday and at that time all bets are off. The state prosecutor doesn't have to make a deal," Padilla said.

Padilla plans to be a part of the search team on Saturday.
