More than 400 pages of documents were released in the discovery phase of Casey Anthony's child neglect case, including an interview with a high school friend of Casey Anthony, who said she was interested in adopting the child.

Casey Anthony was charged with child neglect and filing a false statement in mid-July, about a month after she said she last saw her then 2-year-old daughter, Caylee.

The released documents also include an arrest report and notes from detectives of interviews with Casey Anthony's friends and neighbors. During the discovery process, the prosecution must hand over documents to the defense.

According to the documents, detectives said Casey Anthony, 22, provided many details about the day she said she last saw Caylee, including that she dropped her daughter off with Zenaida Gonzalez. But Casey Anthony did not give specifics, including cell phone numbers, on how to reach friends whom she said could vouch for Gonzalez's existence, according to the documents.

The documents also stated that before detectives arrived to perform a search of the back yard of Casey Anthony's parents' home, Cindy Anthony, Caylee's grandmother, checked inside the sheds and George Anthony, Caylee's grandfather, moved a playhouse and looked underneath concrete pavers for "any evidence of foul play."

Detectives said they also noticed a strange, suspicious depression near the swimming pool, the documents stated.

Deputies have also searched for Caylee after receiving tips of possible sightings of the missing girl, including going to a Chuck E. Cheese's in Altamonte Springs and a bank near Apopka, documents said. Detectives seized videotape from the locations and confirmed Caylee was not present during the alleged sightings, according to the documents.

Casey Anthony also provided an e-mail to detectives that she said she received from her boss at Universal Studios, the documents said. The e-mail was signed by Thomas Frank, whom Casey Anthony said was her boss, but investigators said he does not exist.

Casey Anthony, who is being monitored by an ankle bracelet while on home confinement at her parents' house, made a scheduled visit to her case manager, who will verify that she is meeting the conditions of her bond.

New Theory Presented

The celebrity bounty hunter who helped orchestrate the release of Casey Anthony from jail said he believes she handed Caylee over to friends to get away from her parents' overbearing supervision.

Leonard Padilla, who helped post Casey Anthony's $500,000 bond, told Local 6 News that he believes Casey Anthony and her friends are now caught in a web of lies.

"She can't go to law enforcement and tell them the truth because she doesn't want to get her friends in a jackpot because they've already lied to law enforcement," Padilla said.

Padilla said that he intends to follow leads and tips -- without the assistance of law enforcement -- in the search for the missing girl, Local 6 News reported.

"The issue is (to) get the little girl back, call law enforcement, get immunity, tell them you lied (and say) 'Here's the child, go get her,'" Padilla said.

Padilla said he plans to prove within five days that Caylee is alive.

Spokesman: Mom Trying To Help

A spokesman for the Anthony family said Casey Anthony is trying to help her family find Caylee.

However, Casey Anthony's parents, George and Cindy Anthony, are upset with continued media coverage focusing on their daughter's possible role in Caylee's disappearance.

It has been a circus outside the Anthonys' Orlando home since Casey Anthony got out of jail on Thursday.

Cindy Anthony, Caylee's grandmother, said the frenzy is affecting the whole family.

Casey Anthony is confined with an electronic ankle device to the home. She faces charges of child neglect, making false statements and obstructing the investigation to find the girl.

Mom: I'm Innocent

Casey Anthony said "I'm innocent" while walking out of jail on Thursday and encountering a frenzied mob of reporters and photographers in a case that continues to grab national attention.

Casey Anthony left the Orange County Jail after celebrity bounty hunter Leonard Padilla helped post her $500,000 bond.

Casey Anthony's attorney, Jose Baez, said she wanted to walk out of the jail with her head held high before being rushed by the media.

"Just as we were walking out, I covered her up and she stopped me, and you may notice we stopped for a brief moment and she told me in my ear that she wanted me to take the umbrella down and she said to me, 'Jose, I'm innocent and I'm going to walk out of this place with my head held high.' We were about to do that and you all bombarded us. You could have had all of the photographs you wanted," Baez said.

Baez then threatened to cut off some media channels.

"I discussed certain things with the family and what we've decided that if there are any channels or media outlets that continue that type behavior or violate their privacy by coming on their property -- basically crossing the line -- and I think you are all adults and you know what crossing the line is and what aggressive reporting is and things like that is," Baez said. "That is not going to happen any more. If you do, we will cut off that channel from any interviews and any statements and that channel can get their news from another channel. If you want to be on that blacklist or whatever you want to call it, continue that type of behavior. We are just not going to put up with it. We don't have to put up with that."

Baez said someone tried to get underneath an umbrella shielding Anthony.

"I didn't know if they were going attack us or what they were going to do," Baez said. "I don't know any of you from anywhere. No one should be invading anyone's private space that way. I ask you and plead with you all to please respect my privacy and my client's privacy and her family's."

Baez said he was disgusted by the crowd's actions.

"No one has the right to go pushing against me or her just to get a sound bite," Baez said. "To be quite honest with you, I was really disgusted by the whole thing."
