Jose Baez on Casey Anthony: What a Head Case! >>Hollywood

In his new book, Casey Anthony's defense lawyer Jose Baez says the accused child killer lived in a "fantasy world" and has "serious mental health issues."

Presumed Guilty, Casey Anthony: The Inside Story is Baez's account of last year's sensational trial. In it, he says Casey's lies to police weren't proof of guilt.

Instead, he says they're indicative of her obvious mental problems.

As for why Baez decided to write a book about the trial, he says:

"I wrote the book because there was so much that people didn't know, and still don't know. This book is more than 420 pages of nothing but the inside story."

"My goal wasn't to change anyone's minds. My goal was to tell the story and if people change their minds, it will be because [they learned] more facts."

"I think people's reaction will be surprised at how much they don't know."

For instance, describing in the book why Casey Anthony took police officers to Universal Studios to look for her daughter, Caylee Anthony, Baez writes:

"[Detectives should have realized] right away, 'Wait a minute, we're clearly not dealing with someone who is playing with a full deck.'"

Anthony originally told the police Caylee was taken by a babysitter named Zanny the Nanny (Zaneida Gonzalez is suing her for defamation) and that she'd been searching for her for a month before reporting Caylee missing.

During the trial, Baez argued that Caylee accidentally drowned in the family's swimming pool while Casey and her father, George, were at home, and that George allegedly hid the body, which George denied adamantly.

In the end, Casey was found not guilty of murder, if not in the court of public opinion. She has been in hiding for almost the entire year since.

Baez also details why Casey Anthony did not testify at her trial.

"We had everything to lose and very little to gain," he says.

He also criticizes the media, Prosecutor Jeff Ashton and some of Judge Belvin Perry's rulings, though he did respect his ability to choose a fair jury.

Baez reveals that Casey had a cheeseburger, fries and milkshake from Steak 'n Shake for her first meal after being released from jail last July.

Then, he writes, she flew via private plane to St. George Island on the Florida Panhandle before going to New York and vanishing into hiding.

Anthony is now back in Florida on probation for check fraud.
