He defended her BUT now lawyer JOSE BAEZ defames former client CASEY ANTHONY as having “serious mental health issues” in his new book.

Presumed Guilty, Casey Anthony: The Inside Story, Baez said the detectives working the murder case should have realized that Casey was living in a “fantasy world,” and that she was someone with “serious mental health issues.” reports that Baez writes in his book that when Casey took detectives to Universal Studios where she pretended to work, they “should have stopped and realized, ‘Wait a minute, we’re not dealing with someone who is playing with a full deck.”

Baez dishes more details about the sexual abuse Casey allegedly suffered by her father George Anthony, and he says this contributed to her mental health issues.

George’s attorney, Mark Lippman, declined to comment, saying he hadn’t read the book yet.

Baez also gives details about how Casey fled from Orlando upon her release from jail.

He said once he and Casey, in a bright pink Polo shirt, got into the SUV they went to a parking garage and then got into another car while four of the same decoy cars left at the same time.

With Casey he boarded a private plane and went to the Florida Panhandle resort community of St. George Island and members of their legal team and their families met with them.

Casey then went to New York, where she remained until she was ordered to return to Florida to serve her probation.

Jose also revealed what Casey’s first meal was after being released from jail – a cheeseburger, fries and a milkshake from Steak ‘n Shake.
